An Ordinary Teenage Sex Life

Chapter 10: Sister II

“Oh, gawd… oh, gawd… fuck me, Ben! Fuck me!”

Brandi looked so amazing bent over on all fours. She really did have a dynamite ass. And I felt incredibly lucky to have been the one to stick my face between her cheeks and lick her and suck her and squeeze her until she came all over my face.

My face. Not Brian’s. No, he was still dreaming about doing what I was doing to Brandi. And I was determined to screw my sister so well that she’d come home to me for the summer or maybe spring break, complaining about how she hadn’t gotten a proper fucking since she left and how she needed me to boink her lights out.

With that pleasant thought, I knelt behind my older sister, slipped my dick into her from behind, and then proceeded to fuck the shit out of her. I gripped her hips and really started laying the pipe, plunging into her the darkest recesses of her vaginal tunnel with every stroke.

And just when I felt myself about to cum, I reached around and tweaked her nipple, her left nipple, the one that seemed to be hardwired to her clit. And with my right hand I started strumming her clit itself, the dual stimulation enough to push Brandi over the edge and send her screaming into orgasm.

“Aaaaaahhhhh!” my older sister wailed, and then I was joining her in yelling as I flooded her pussy with my latest load of incestuous spunk.

Almost immediately after I finished sperming her, Brandi collapsed face-down on her bed and lay there, gasping for air. I managed to keep myself upright for a little longer before leaning back and then sinking my naked butt onto my heels.

When we both had caught our breath, I slid off the bed and ducked down briefly to place a soft kiss on Brandi’s butt. Then I rapidly left little pecking kisses up my sister’s spine until I got to her head, where I tilted my head to the side and gave her a warm, tongue-filled kiss of passion.

When we were done with that, the beautiful teenage brunette with blonde highlights picked her head up and propped it on one hand, supporting her head with her elbow. “Why didn’t we do this sooner?”

I shrugged. “You were waiting for me to grow up.”

She sighed. “Riiight.” She huffed. “I wish you weren’t going back to school. I’ve got two more weeks of Winter Break and I’m going to spend half the time wishing I was in bed with you, Ben.”

It was the first day of school in January. The air was crisp and filled with the hum of high school students refreshed by two weeks of vacation.

“Hiii, Ben…” Cassidy sashayed up to me and planted a firm kiss on my lips while rubbing her ample boobs into my chest. When she broke for air, I saw that there was another cute girl walking up to us.

“Hiii, Ben…” Megan neatly slid in and planted a firm kiss on my lips while rubbing her pelvis against my crotch. When she broke for air, I saw a third figure walking up to us.

“Hiii, Ben…” Kenny Doyle said in a mock-female voice, moving closer to me and obviously puckering up.

“Fuck you,” I grinned and shoved Kenny in the chest, playfully knocking him back on his heels.

“What? Too many girlfriends already?” He said in pretend-disappointment.

I grinned. “You can never have too many girlfriends. I just don’t want any BOYfriends.”

“Hey!” Megan pushed my shoulder. “You’ve got plenty enough girlfriends. Got it, buster?”

“Of course, of course,” I smiled and bowed my head in deference to her.

“Besides,” Cassidy drawled while winking at Kenny. “Didn’t the two of us completely wear you out on Saturday?”

I sighed and remembered the night before last. Cassidy’s parents had gone out to some party, leaving our trio four hours of playtime. I probably could have lasted a bit longer, but unbeknownst to my girls, Brandi had sucked a load out of me just before lunch.

“That was a fluke,” I said while puffing up my chest with as much teenaged ego as I could muster. “Only because you guys mentally drained me with your convoluted ‘decision’.”

Both girls smiled. Last week, after both returned from their family trips, my two girlfriends had gotten together to discuss our three-way relationship… WITHOUT me. Then, on Saturday, the two of them sprung their “decision” on me, each of them alternately explaining to me my role while the other gave me a blowjob to ensure I agreed to every one of their conditions.

In a nutshell, they valued their friendship over and above their love for me. They’d hated how their petty jealousies made them compete over me, and resolved to stop fighting each other. No one boy should drive them apart. At first, I’d panicked and thought this meant they would both break up with me. It just seemed logical to remove the object of conflict from the field.

But while Megan was explaining this, Cassidy was giving me a blowjob, which seemed to preclude the “breaking up” theory.

For some reason that perhaps only made logical sense in the minds of 16-year-old girls, I made each of them happy and they wanted to continue being my girlfriends. I was given a very simple set of rules: [1] Don’t cheat on them, [2] Don’t play favorites, and [3] Be ready to explain to one girlfriend exactly what I had done with the other girlfriend.

The first rule was obvious. Megan reiterated her “chopping off of my dick” warning should I violate the first rule. I knew I’d still be boinking Brandi for two more weeks, but I didn’t consider my sister to be cheating.

The second rule was designed not to inflame a woman’s natural impulse for jealousy. There would be no “first” girlfriend or any other favoritism. They were equals and both girls resolved to do their best to not try and “out-do” the other.

And the third rule was their safety check. No more secrets. No more sneaking off for a Tuesday rendezvous with Cassidy to be kept hidden from Megan. If one girlfriend tried to break the second rule, the other girlfriend could ask me about it and expect a straight answer.

Me? I thought the whole thing was a house of cards just waiting for a stiff breeze. Teenaged girls aren’t much better than teenaged boys at thinking rationally 100 % of the time and I just knew there would be some event in the near future that would force us all to move on, grow up, and see other people. But for now, I had two cute girls who both wanted to screw my lights out, starting with this afternoon’s Monday study group.

“Well, you two may have ‘worn me out’ on Saturday,” I drawled. Then I grinned salaciously at my redheaded girlfriend. “I’ll show you worn out this afternoon.”

Cassidy giggled, Megan blushed, and Kenny just sighed with jealousy and shook his head. Then he turned away to head off for his first class.

But before he could leave, a fourth figure came down the hall.

“Heyyy, Ben,” came the sultry, sweet voice from my left. I glanced over to see Adrienne Dennis cruising along as if modeling on a catwalk, her spray-painted jeans hugging her curves, a blue V-neck with lighter blue long-camisole underneath hugging her big bosoms and drawing the attention of everyone to her tits.

She slowed down and smiled at me. “How was your vacation?”

Without fear or intimidation, I squared my shoulders and just smiled back. “Good. Yours?”

“Just great.” Adrienne turned her gaze to my girlfriends and also to Kenny, who was visibly drooling as he ogled the gorgeous cheerleader. “See ya later.”

Both Kenny’s and my eyes automatically followed the sway of Adrienne’s ass as she glided away. And then once she got halfway down the hall I pulled back and glanced at my girls. Both Megan and Cassidy were glaring at me heatedly.

I shrugged. “What?”

I felt something tickle my balls, and with a start, I jerked awake.

Brandi was bobbing her head up and down in my lap, slurping noisily. But despite the wet heat and her sucking mouth, I wasn’t feeling a whole lot coming from my nether regions. I was both worn out and worried about getting caught.

“Brandi!” I hissed in a quiet voice. “What are you doing?”

She popped off with a frustrated look. “That’s a dumb question.”

I rolled my eyes. “It’s 6:30! EVERYONE is still home!” It was hard to keep my voice down with the panic rising inside me.

“Calm down, calm down,” my older sister glared at me, her eyes turning her words into an order. At least she was fully dressed. If anyone came in, she could quickly tuck me back into my shorts and we might be able to fake looking normal, especially because I wasn’t that hard.

“C’mon, Ben, what’s wrong with you,” Brandi whined while trying to jack my cock. “Don’t worry about Mom and Dad. They NEVER come check the bedrooms before breakfast.”

“It’s not them,” I sighed. “Megan and Cassidy really wore me out yesterday. I mean REALLY wore me out.” With school back in session, my girlfriends both wanted to restrict our extra-curricular activities to the Monday study group and Friday night dates. Oh, there would be the occasional weekend visits and they reserved the right to request a mid-week tryst at Cassidy’s house, but in order to focus on their studies, we were limited to two regularly scheduled fuckings per week.

So both girls really wanted to make those two times COUNT. It was like dating Megan last semester, only times two. And 16-year-old boy or not, there’s only so much a human body can take.

“C’mon, Ben, please? If not now, when? Brooke and everyone will be home after school.” And with that, Brandi started to open up her pajamas, bringing my hand up to her naked breast. And as she dragged her panties and pajama pants down, I felt a stirring in my dormant cock. “THERE we go…”

“If we get caught, we’re SOOO dead,” I sighed. If anyone barged in now, there would be no explaining a naked older sister. But viewing my older sister’s nude body had done the trick, and as my dick rose, we both knew there would be no further protests coming from me.

“We won’t get caught,” Brandi said confidently as she moved into a sixty-nine over my body. So with a little oral loving on my part while she rode my face, we were both soon ready and Brandi turned around and sank herself down onto my cock. And then she rode me until we both had satisfying, if muffled, climaxes.

When we were done, Brandi cleaned herself up and then redressed. Before she left, she paused and turned to me. “Have fun at school,” Brandi smiled as she blew me a kiss. And then she slipped out the door and back to her own bedroom.

“Who’s worn out now?” Cassidy teased when I dragged myself to class with big bags under my eyes.

These three girls were going to kill me.

Just before fifth period, Adrienne fell into step with me, my gaze momentarily drawn down to where her big tits wobbled enticingly in her too-tight top. “Wow Ben. You look like you’ve been fucked half to death.”

Despite my exhaustion, I couldn’t help but grin with pride. “Yeah…”

The gorgeous blonde sighed and clutched her books tighter over her chest. “I’m sooo jealous.”

“C’mon, now that football season is over, I’m sure Jake has a lot more time for you.”

Adrienne smirked. “Time, we have. Skill on the other hand…” she sighed. “Jake is all muscles and thumbs and he only knows how to fuck at one speed. Sometimes I don’t know why I’m with him.”

“Because he’s the most popular guy in school and that makes you two the most popular couple in school?” I ventured with more than a little sarcasm in my voice.

Adrienne pouted. “You say that as if it’s a BAD thing.”

I held my hands up. “Hey, I’m not going to tell you how to live your life. You’ve got every girl in school wishing she was you, including my girlfriends.”

Adrienne smiled and then stopped dead in her tracks. I took two more steps before stopping myself and turning to face her while her eyes darted back and forth for a few seconds. And then Adrienne looked up at me with a look of pure lust on her face. “If every girl wishes she was me, why do I find myself wishing I was one of your girlfriends?”

Even a confused frown couldn’t detract from Adrienne’s raw physical beauty. Her eyes sharpened and perfectly sculpted eyebrows pinched in, simply giving her a more dangerous and angular look. She stared at me for a long few moments, her jaw quivering as real anger started to come into her eyes. And then without another word, she strode past me in a hurry.

“Adrienne?” I asked.

“Fuck off, Ben,” she spat and marched away.

I’ll never understand women.

That night, just after 11pm, I cornered Brandi in the kitchen while she was pouring herself some coffee. Habit from college. Everyone else was upstairs and asleep already, so I wasn’t too worried about being interrupted.

“Look, sis. I LOVE what we’re doing, but we need to figure out some ground rules. You can’t keep sneaking into my bedroom when the whole family is still in the house! Especially in the mornings when someone might wake up!”

Brandi pouted, “I was horny. I didn’t have a single orgasm all Monday.”

“And you know I’m happy to help you out with that, but we can’t keep taking risks like that. We can tell Mom we’re driving to the mall or something; I know a few places we can park. But not in the house. There’s just too big a chance of you getting caught sneaking out of my bedroom if someone wakes up early.”

“What about now? At night? Everyone else is asleep. I’m good at keeping quiet.”

I sighed, “Maybe.” I started thinking about other ways we might get caught.

Brandi just grinned and set her coffee mug down. Then she dropped her pants and panties to the floor in one fluid motion before hopping her butt onto the kitchen counter right beside her coffee. Then she spread her legs to the sides and husked, “Eat me, Ben.”

“Brandi!” I hissed.

“Everyone’s asleep. C’mon. We won’t get caught,” Brandi said confidently.

I sighed.

“Besides, don’t you wanna taste my pretty pussy?” My sister spread her legs and I sighed again. My hormones had already made my decision for me.

Bracing my hands on the counter’s edge, I bent and took my first lick along her closed slit, sending shivers up my sister’s spine that had nothing to do with the cold granite surface.

Brandi giggled and reached down to her coffee mug, picking it up and taking a sip even while I continued licking her snatch. “Thanks, Ben. You’re the greatest little brother in the world.”

After satisfying my older sister on Tuesday night, she kept her word on Wednesday morning. She let me sleep in and didn’t sneak into my bedroom. So I woke up with my alarm clock and for a brief second, I regretted not letting Brandi wake me up with a blowjob.

The same went for Wednesday night and Thursday morning. Brandi and I quietly screwed, twice, close to midnight before nearly falling asleep together. I would have been really awkward for our parents to find us like that in the morning. Fortunately, she woke up and snuck back to her room.

That’s not to say that my relationship with my sister was nothing but late night screwing. Brandi wanted to go more than once every night, and even though I had teenaged hormones, I needed a little downtime between shaggings to recharge.

During those breaks, I learned a lot about my sister that I’d never known before. Sure, I was aware that she hated peas because Mom had to go out of her way to make an extra vegetable at dinner times. I knew stuff like that. But I’d never known that Brandi had grown up wanting to be an Astronaut; and that when I was a baby she would pretend I was her co-pilot as we flew to the moon on the couch/rocket ship. I’d never known that the only reason she was an Econ/Accounting major was because Mom and Dad put so much pressure on her to be the successful, eldest child and go into business. She really wanted to be an Art History major, and she’d spent a lot of time at all the museums in the greater L.A. area.

And I found out that Brandi never swallowed for any of her other boyfriends. She only did it with me because she loved the naughty little thrill of knowing she was swallowing down her little brother’s cum, and that thrill outweighed the bad taste. I certainly would never have known that under any other circumstances.

So I learned a little more about her each day. And the next day, things were just that much more comfortable between us hanging around in the evenings, both of us with little grins at the knowledge of what we’d get to do the later that night.

After school on Thursday, Megan and Cassidy kept their word by NOT inviting me to Cassidy’s house for sex for the third weekday in a row. We all had a ton of homework and other new assignments from the start of the new semester, and the girls were both top students and dead set on staying that way.

I did make one mild complaint when I parted ways with Megan in the parking lot while Brooke and her little boyfriend, Perry Anderson, were giving each other goodbye smooches. I whined to Megan, “I know you said nothing regular, but I WAS hoping for the occasional mid-week or weekend.”

Megan giggled, “Men. Always thinking with your dicks. It’s only been THREE DAYS, Ben.”

“Okay, okay,” I didn’t want to press the issue. That was part of my reputation, I never pressed the issue. And because I didn’t press, my girlfriend was very happy with me and gave me a very passionate goodbye kiss to let me know she was very happy with me. Megan wanted a loyal, understanding boyfriend who would complement her life, not dominate it, and I was dedicated to being that boyfriend.

Besides, even though I really wanted to have a threesome with Megan and Cassidy, I’d still get to have a late night sex session with Brandi. I could survive until my Friday night date with the girls.

It’s just that I wanted BOTH.

But Megan and Cassidy didn’t know that. They just thought I was a patient and understanding boyfriend who had my libido in check. And that meant that my girlfriends were even happier with me as their boyfriend.

I had a very near-perfect situation. Not only did I have TWO cute 16-year-old girlfriends whose ideas for a good time were to tag team me and never stop until I was sexually satisfied, but I also had a beautiful older sister whose idea of killing time during Winter Break was to fuck me every night and take my incestuous spunk deep in her clasping pussy.

Of course, perfect situations never last for long.

“Brandi… Brandi…” I huffed. “This is dangerous…”

“Relax, Ben. We won’t get caught,” my sister took her mouth off my cock and panted for air, licking her lips. “I told you, the twins are gone for the day and Brooke walked to Jennifer Vo’s place. With Mom and Dad visiting Aunt Mary, you’ve got nothing to worry about.”

Brandi then grinned at me and pushed at my torso, shoving me back into the armchair so that I slumped lower and pushed more of my dick into her mouth. I did try to relax. I let my body sag into the backrest. I closed my eyes. And I put my hands on top of my sister’s head as she bobbed up and down my prick. It was a lazy Saturday and everyone was out of the house. I had nothing to worry about.

And yet I couldn’t get the little alarming tingle out of the back of my head.

Presently, Brandi deemed me hard enough for fucking and she quickly stood up and dropped her panties. She was wearing a skirt this day and simply hiked the material up to her waist, showing off her toned thighs, and then she straddled me and tugged my cock into position.

While Brandi mounted me and impaled her pussy on my dick, I slid the shoulder straps of her shirt down her arms and tugged the neckline down to expose her tits. The high-set, round melons were lightly supported by her bra, but I reached around and unsnapped her to free her tits enough so that I could pull them up and fasten my lips around a nipple.

“Ohhh… fuck me, Ben…” Brandi crooned into my ear while clutching my head to her chest and bouncing herself up and down my rod.

I did as requested, using the springiness of the couch cushion to help my thrusting while I pinched both of my sister’s breasts together so that I could feast on them together.

And that’s when we heard her.

The light whimper was quiet, very quiet. But I was between grunts and Brandi was between gasps, leaving a vacuum of silence in which the little whimper was just loud enough to carry across the room.

I immediately froze and went straight into a panic. We were caught! My worst nightmare had come true! Who had caught us? Was it Mom, back home unexpectedly to find her two eldest children committing incest? Or heaven forbid, was it the twins, who would be forever scarred by witnessing such a depraved sexual act before their immature minds could handle it?

Even worse, was it one of my girlfriends come to visit me? I didn’t consider screwing Brandi to be cheating, since she was family and no possible threat to displace them as girlfriend, especially once she flew away in another week. But even if I didn’t consider it cheating, Megan or Cassidy might. I would miss my dick if Megan followed through and chopped it off.

But while I froze and panicked, Brandi was much more decisive in her actions. She immediately spun to look for the intruder and quickly spotted the skulking teenager trying to hide behind the loveseat opposite us.

“Brooke!” Brandi screeched in an angry and annoyed voice. “What the FUCK are you doing here?”

Almost instantly, our 14-year-old little sister popped her head out with wide-eyes locked onto the fucking couple in front of her. Nervously, she stammered. “Uh… Jennifer’s family was out. No one was home. So I came back.”

“How long have you been watching us?” Brandi frowned and pinched her eyebrows together. She did not, however, make any move to get off my dick. At least I figured her skirt would be covering most of our joining from view. And since Brooke was in a position behind Brandi, I figured she would not have had a view of me nibbling on our older sister’s tits. Maybe it wasn’t so bad, no real skin observed.

Brooke just shrugged and replied, “Since you were giving Ben a blowjob.”

Oh, crap. That meant that my little sister had now seen my erection. How would I be able to even look at her across the dinner table or while driving her to school without knowing that little fact? Immediately, I felt myself going soft inside of Brandi’s pussy.

My older sister felt me deflating inside her and she sighed. Shaking her head, Brandi winced and pleaded, “You can’t tell Mom and Dad.”

Brooke nodded, but then that evil little gleam came into her eye. You know, the one she had when she wanted to blackmail me into setting her up with my best friend Kenny. Damn devious 14-year-olds. “I won’t tell,” Brooke promised, “if you do something for me.”

Brandi looked defeated and just sighed, “Anything.”

It was at this point that I noticed the flush in Brooke’s skin and saw that her jeans were unbuttoned. She must have been masturbating while watching us, and now I remembered how Brooke had looked while we listened to Brandi and her potential boyfriend Brian having phone sex. Just a little bit, I felt my cock stirring with new life. And then Brooke smiled and said, “I want you guys to teach me how to give a blowjob.”

Brandi erupted, “What? Oh, HELL no. No, you’re too young!”

Brooke frowned. “How old were YOU when you gave your first blowjob?”

“I was too young,” Brandi insisted stubbornly. “I wasn’t ready and it was horrible experience.”

“That’s why I’m asking YOU,” Brooke reasoned. “You guys can teach me the right way. Not with some fumbling in the backseat of a car when neither of us knows what we’re doing. Now I’m going to end up trying it one way or another, whether you help me or not. Wouldn’t it be better if you taught me first?”

Brandi was out of breath, frantically looking around while her mind whirled, trying to figure out what to do. She seemed to completely forget that she was impaled on my cock, which had gotten back to half-hard with the sexual nature of our subject matter. With jaw quivering, our eldest sister sighed and nodded. “Okay, okay. You don’t rat us out and I’ll teach you. Let me go get my dildo.”

Brooke pouted. “Why? Ben’s right here.”

Brandi’s eyes flew open as she realized what Brooke was implying. “What? No! He’s your brother! That’s disgusting!”

Brooke pointed right at our crotches, where in her twisting, Brandi’s skirt had ridden up and we could all clearly see that my rod was still buried in my older sister’s twat. “YOU don’t seem to find it so disgusting. And I don’t either. I think Ben’s very sexy.” And with that, I felt myself get to full hardness. The thought of Brooke sucking my dick was just too viscerally arousing to ignore.

As if only now realizing what position we were in, Brandi quickly jumped off my lap, my stiff erection exiting her vagina with a wet squishing sound. And then Brandi stomped over to Brooke, grabbing the younger girl’s hand in her own and tugging her away. “No, no, no,” Brandi huffed.

“Why?” Brooke pouted. “You just trying to keep him all to yourself?”

“No! He’s not even mine. He has girlfriends. Two of them, remember?”

Brooke shrugged. “He was having sex with you. So why not me?”

“You’re TOO YOUNG,” Brandi insisted.

“I’m fourteen!” Brooke exclaimed. “I’m old enough to have my period and old enough to have breasts and I’m old enough to be really, really horny!”

“I made a mistake, Brooke. I committed incest. I crossed that line. And nothing I do can ever change that,” Brandi sighed. “But not you. You haven’t crossed the line. You’re still pure. Stay pure, Brooke.”

Brooke folded her arms over her chest and turned to look pointedly at me, where I was still in a half-daze from shock and pleasure. My wet dick was still upright and bobbing in the air.

“What if I don’t want to stay ‘pure’?” Brooke clearly had no internal moral conflict with ogling my naked body. “Looking at Ben like this gets me all squishy inside.”

“For God’s sake, Ben. Put your shorts on!” Brandi yelled at me. And at the command tone in her voice I automatically moved to obey. Then Brandi whirled back to our younger sister. “You can’t do it to Ben, Brooke.”

“Then I’ll rat you out to Mom and Dad,” Brooke glared coldly at her older sister, that evil glint back in her eye.

“Whatever, I don’t care,” Brandi huffed. “I can’t change the mistakes of my past; but I can keep you from doing the same. Even if it means Mom and Dad finding out about me and Ben. C’mon, Brooke.”

With that, Brandi grabbed the younger girl’s hand and started tugging her down the hallway. “You’re going to your room. And you’re gonna stay there. You’re grounded.”

“What for?” Brooke whined. As eldest child, Brandi had been given some disciplinary privileges, although she rarely invoked them.

“For trying to blackmail us.”

Curious, I followed after the girls as they went to the stairs. Then, once they got to the upstairs landing, Brandi turned and gripped both of Brooke’s shoulders. “Listen to me carefully, Brooke. If you tell Mom and Dad about what me and Ben have done, it could really fuck up this family. They could send me away and never let me come home. They could send BEN away; because he’s a boy and they might worry he’ll do the same to you. You don’t want to ruin this family, do you?”

Wide-eyed, Brooke shook her head ‘no’.

“Look, I can still teach you. I’ve got dildoes we can practice on and I’ll teach you everything you want to know. But not on Ben, okay? Not. On. Ben. That’s morally wrong.”

“Why?”

“Because it IS, okay?”

Brooke pouted. “It’s not like I can get pregnant from giving him a blowjob.”

Brandi sighed. “It’s not that. Blowjobs make you want to do other stuff, stuff that CAN get you pregnant. You’re not even on the pill, Brooke.”

Brandi then glanced at me with a worried expression before turning back to face her little sister. Again she shook the younger girl’s shoulders. “I KNOW what’s going through your head. I was 14 once, too. Brooke, PROMISE me you won’t try to seduce Ben or do anything sexual with him. PROMISE me.”

“But—”

“No buts. PROMISE me.”

Brooke grimaced, rolling her eyes. “FINE. I promise.”

Brandi sighed with visible relief. “Now go to your room and stay there till Mom and Dad come home. You’re still grounded until then.”

“But you said you’d teach me!”

Brandi exhaled. “Let me talk to Ben first. I’ll bring you the dildoes and I’ll start teaching you today.”

Blinking, Brooke nodded and then went into her own room, but not before giving me a significant look. This wasn’t over yet.

“I’m going to hell.”

“We’re not even Christian, Brandi.” We were both sitting on Brandi’s bed, a place I’d been a few times recently in more intimate situations. This time, however, we were fully clothed and sitting a couple of feet apart.

“I’m still going to hell,” my older sister moaned.

“For what? For doing what makes you feel good?” I shrugged. I was still very horny from our coitus interruptus.

“Ben, you don’t get it, do you? What we’re doing is wrong.”

“I know, you told me,” I replied. I reached up and tapped her head. “Up here, right?”

Then I reached for her left hip, wrapping my hand around to her ass and palmed her breast with my right hand. “But here… it feels so right, doesn’t it?”

“Ben…” Brandi whimpered. “Don’t tempt me.”

I swooped down so that my face was just half an inch away from hers, my lips puckered and ready. She was breathing hard and her eyes were wide as she stared back at me. I could feel the lust pouring off of her. But I didn’t kiss her. I didn’t want to force the issue. Yeah, I was a bastard for tempting her this far, but I wouldn’t take her by force.

I didn’t need to. Brandi hesitated just another second before she leaped forward, planting her lips on mine and clutching my head tightly to her. Her kiss was just as passionate as ever, perhaps even fiercer as she was still fighting the internal conflict between her desires and her morals.

But then a few seconds after she started kissing me, Brandi abruptly pulled away and scooted herself two feet down the bed to distance herself from me. She shuddered and looked at the floor.

“Ben, I need you to promise me…” she said in a halting voice. “I know Brooke promised, but I can’t trust her. I know what it’s like to have these desires… to feel this lust. Please Ben, I desperately need to trust you. You once promised me that no matter what, you would always be my brother. That you would always love me. I need to believe that.”

“I do. I love you, Brandi.” My eyebrows canted to the sides and I gave my sister the most honest and reassuring expression I could. I was still a little horny, but I recognized Brandi’s need for some more traditional family loving.

“You can’t do anything with Brooke. She’s too young and if you fuck her brains out, you’re really gonna mess her up for other boys. Lord, if you did to her half the things you’ve done to me, she’d fall in love with you and never let you go.”

“Whoa, whoa,” I held my hands up. “I’m not gonna.”

“Promise me. Promise that you won’t do anything sexual with Brooke.”

I shrugged, “Of course.” While I was turned on my an aroused female, period, Brooke wasn’t really a sexual creature to me. It was easy to think of Brandi as a sexy young woman. She was fully grown with nice tits and curves and all that, having developed long before me. I’d thought of my older sister as a sexual creature from the time I first thought about sex.

But Brooke? Brooke was my little sister. I still remembered when she was completely flat-chested and child-like, which was NOT a turn-on for me. Only recently had she begun to develop, but even then I still had the mental image of a child in my head when I thought of her.

On top of all that, while Brandi and I had progressed to a sexual relationship that was mutually satisfactory, we’d had to go through a lot of angst and tension to get to that point. It hadn’t been easy and it very nearly ruined our relationship. I wasn’t eager to attempt anything like that with Brooke.

“Not ‘of course’, Ben,” Brandi said harshly. “Promise me.”

“Okay. I promise,” I nodded agreement. “I won’t do anything sexual with Brooke. I’ve got perfectly good 16-year-olds to play with, without all the family complications.”

Brandi sighed and visibly relaxed. But she also hunched over and looked ready to curl into a little ball. My older sister was still quite emotionally in shock over being caught committing incest by our younger sister, and she looked ready to collapse at any moment. So I quickly slid across the bed and wrapped her up in my arms, giving her a firm but brotherly hug.

“I can’t do this anymore, Ben. I can’t have sex with you anymore,” she whimpered. “I want to. Oh, man, I sooo want to, but I can’t. I can’t handle it anymore.”

“Shhh…” I soothed. “It’s okay. It’s okay. I love you, sis. No matter what. We don’t have to have sex for me to love you. I’ll always love you anyways.”

We sat like that for a long few minutes while my older sister composed herself. My touch wasn’t sexual, but I did rub her back soothingly while she shivered and nuzzled her face against my chest.

Then at last, Brandi had gathered herself and was able to sit upright. She stood before I could, sniffling slightly and wiping the moisture from her eyes. And then taking my head in her hands, she bent and gave me a soft peck to my forehead.

It wasn’t an ordinary kiss. There was something symbolic in the way Brandi kissed my forehead. It was as if she’d reverted back to seeing me as just a brother, without even a trace of the lust that used to fill her gaze.

Perhaps ironically, once she’d done this platonic, sisterly act, Brandi immediately then dropped to her knees next to the bed and then started fishing underneath with her hand, coming back out with a small box. In it, she had a small collection of sex toys, and I arched my eyebrow at the handcuffs next to the personal lubricant, and at the monster 12-inch dildo.

Brandi selected a more normal-sized pink dildo, which was shaped like a penis, complete with veins. And then Brandi stood up, frowning at me while sniffling away the last of her tears. “Go downstairs and watch TV or something, Ben.”

I sighed and nodded. She wouldn’t be comfortable if she thought I was anywhere near her or Brooke’s bedroom right now. Standing up, something occurred to me purely out of honest thoughtfulness for Brandi, and I advised, “You should blow your nose first. You’re gonna need to breathe through it for this.”

Brandi barked a short laugh, releasing some of the tension. And then I stepped outside.

Sunday felt like I had rewound my life back to that week after Christmas. Brandi kept to herself, not being obvious about it but avoiding me nonetheless. I had been secretly hoping that despite Brooke “catching” us, she and I would at least continue our sexual relationship until she flew back to college. She was just too accomplished and fantastic a lover for me to simply walk away from.

But that was exactly what Brandi was doing: walking away. True, she couldn’t “un-cross” the line of incest, but at the moment, she had made the decision not to re-cross the line again.

She wasn’t mean or rude. She simply kept her interaction with me to a bare minimum and didn’t say much to anyone else, either. It was as if she didn’t trust herself around me, and she didn’t want to tempt herself into taking things any further than she could handle.

When I did interact with her, there were big bags under her eyes and she seemed especially haggard. She had little energy and obviously the trauma of getting caught, literally with our pants down, had shaken Brandi to a point from which she had not yet recovered. Mom even noticed and asked her what was wrong, but Brandi just complained of a hangover from visiting with friends.

I didn’t push her. I gave my sister her space. I could only hope she came around before she left. I didn’t want us to part on bad terms of any kind, not after the intimacy we’d shared together. I just wished there was some way I could show her that I was there to support her. But every time I wanted to approach her and tell her such, she held up her hands and asked me to give her some time.

Brooke on the other hand, was as normal as any other day. She chatted with me, got annoyed with me, and included me as a big brother without any hesitations or altered behavior. I wondered if that wasn’t the first time Brooke had spied on me and Brandi.

At least she was back to completely normal…

… or so I thought.

I felt something tickle my balls, and with a start, I jerked awake.

“Mmph!” somebody groaned and as I sat up I realized I’d just shoved my dick an inch into my sister’s throat. She gagged slightly and then popped off to catch her breath. And then her bangs fell back and I got a good look at the girl’s face.

“Brooke!” I hissed. “What the hell are you doing?”

“Practicing!” And before I could react, my little sister ducked her head back down and wrapped her lips around my shaft, going lower and lower until she’d taken as much of me as she could, which still left a couple inches of my shaft exposed. And then Brooke began sucking and I groaned as I felt her licking at me like a popsicle.

But then I remembered my promise to Brandi. And that memory also spiked my own protective concern for Brooke in matters of vice. She was only 14! She was WAY to young for this. Hell, I hadn’t even gotten to third base until I was 16!

“Brooke, no,” I said in a commanding tone, which caused her to at least stop sucking, even if she didn’t remove her mouth from my dick. I reached down then and took hold of her head, gently tugging upwards until she popped free, a string of saliva still connecting her wet lips to my wet mushroom head.

“Aww!” she protested and fought me for a second before finally relaxing. I quickly tucked myself back into my boxer shorts and pulled the blanket over me.

“Brooke, you PROMISED Brandi. We can’t do this.”

“Why not? It’s not like I can get pregnant,” she rehashed her previous rationalization.

“That’s not the point. We just can’t, okay? It’ll mess up our brother-sister relationship.”

“You did it with Brandi.”

“She’s older. And it STILL messed up our relationship.” I sighed. “She’s not talking to me right now.”

Brooke pouted and folded her arms over her chest, looking like she was developing another argument.

“Look. If you’re so determined to start giving blowjobs and you’re POSITIVE you won’t have sex, why don’t you practice on your boyfriend… uh, Perry?”

Brooke’s eyes opened up and she gave me a ‘well-duh’ expression as if I should’ve already known the answer. “Because I want to make sure I’m doing it RIGHT before I try it on him. I don’t want to mess it up. If I give him a bad blowjob, he might break up with me.”

I rolled my eyes. “Believe me, Perry won’t care. He’ll just be thrilled you’re sucking him.”

“Still,” Brooke continued pouting. “I want to do it right. Why won’t you help teach me?”

“Because I’m your brother.”

“That’s WHY you should be the one to teach me.”

“About boys in general. About how to stay safe. And maybe TALKING about sex stuff. Not actually HAVING sex.”

“Why not?”

I sighed. “I don’t know. Because I feel… weird… about DOING anything with you. You’re just too young. You’re my kid sister! And because I promised Brandi.”

“You also promised ME. Back when you didn’t want me to date Kenny Doyle. You promised ‘any favor’ at ‘any time’. This is my favor. Teach me, Ben.” And then Brooke opened her mouth and put on a sultry face, miming that she wanted to suck my dick.

I groaned. Memories of my little sister as a pre-pubescent child or not, Brooke HAD grown up into a pretty well-developed 14-year-old, complete with pretty face, coltish body, and cute tits. The male in me reacted instinctively to an arousing female, and my cock was still hard. But I was TRYING to be a responsible young man.

“C’mon, Ben. It’s just a blowjob. It’s not like I’m gonna fall in love with you or something.”

“No, Brooke. Any favor but sex. I don’t think you’re old enough and I promised Brandi that I wouldn’t.”

“But—”

“No, Brooke. I’m not talking about this anymore. You’ve gotta go. Brandi already is upset with me and you being here is NOT going to help. Please? Look, I’ll answer your questions. I’ll even buy you a dildo once Brandi leaves and teach you or help you practice or something. But not on ME.”

Brooke pouted. “FINE. Some brother you turned out to be,” she bitched as she got off the bed and turned away. “Can’t even keep his own promises.”

Seconds later, Brooke stomped out the door. She didn’t even bother to close it all the way.

I hadn’t realized how tense my entire body had gotten during that little exchange. As I flopped onto my back, I felt like every muscle in me was overtightened and it actually hurt to lie down. There was a crick in my neck and no matter what I did, I couldn’t quite stretch out my spine.

I was so busy groaning and trying to relax myself that I never heard or saw the door swing open. I didn’t know I wasn’t alone until Brandi sat next to me on the bed.

Without a word, she simply looked down at me and pulled the blanket back. Then reaching to my crotch, she slipped her hand inside my boxers and wrapped her fingers around my erection, which was still rock hard from Brooke’s blowjob and my own sexual anticipation.

Brandi squeezed it twice, as if testing its hardness. She even glanced down to inspect my pee-hole. And then, still without speaking, my older sister got up and left.

It had been a WEIRD Monday morning.

“Oh, FUCK, Ben! Are you still hard?” Cassidy moaned when my body automatically started pumping in and out of her saturate pussy in slow rhythm. I’d nutted into her not three minutes earlier, but rather than pull out, I’d stayed embedded and simply put my forehead down to the mattress while breathing heavily.

Since I supported most of my weight on my elbows, Cassidy had been in no hurry to push me off her chest. She hugged me to her and enjoyed the intimate cuddle with her boyfriend, kissing my neck and rubbing my back while she felt my semen soak into her eggless womb.

I was too busy trying to exorcise the demons from my head. I had machine-fucked Cassidy, pounding away at her with metronomic precision while my mind was elsewhere. I was going over all the mistakes I’d made in not restraining myself with Brandi. She was hot, she was sexy, and I’d wanted her body. I spent all my mental energy convincing her to just go with her lustful urges and that everything would be alright in the end. I just never stopped to consider how I might be irrevocably ruining my relationship with my older sister.

But if I had the chance to do it all over, I probably would still opt for becoming intimate with Brandi. The sex had been amazing, but the way our relationship had changed for the better was also wonderful. She wasn’t the tyrant anymore. I wasn’t the ‘too-little’ brother anymore. We were both young adults and Brandi had treated me with respect as an equal for the entire time we’d been fucking. If we could just resolve her moral quagmire, we’d be fine.

While I was lost in my mental ruminations, my body instinctively knew what to do. Once the post-ejaculate hyper-sensitivity went away, my prick realized it was embedded inside a warm, tight pussy, and slowly it sent the signals to make me pump in and out, delighting in the friction the motion produced. I wasn’t trying to fuck Cassidy again just yet, just casually using her pussy as a gentle masturbatory device to get a little pleasant, low-key stimulation.

But my other girlfriend had other plans. Megan knelt on all fours beside us, bumping her hip against my side. “If you’re ready to go, Big Ben, I’ve got two lonely holes just waiting for your visit.”

Megan’s words slowly filtered into my brain while I was gently screwing Cassidy. I actually had a delayed reaction before I turned my head and slowly pulled out, the redheaded teen beneath me whimpering as I exited her.

“Come on, Ben. Fuck my little pussy. Drill me. And when you’re ready, I lubed up my asshole for you. I’m ready for you to fuck my ass again.”

I felt my eyelids twitch as Megan’s words penetrated my brain. The raw lust in her voice cut through the fog in my head like a knife, and I pushed away my contemplative thoughts in favor of a visual observation of Megan’s nice body. Petite and slender, with gentle swells at her hips over nice legs. And my brunette girlfriend had a very cute ass which was wiggling in anticipation of my arrival.

In fact, her ass looked similar to what Brooke’s ass might look like naked. And with that thought, a surge of adrenaline pumped into me and as my cockhead settled between Megan’s labial lips, I thrust forward and pierced her pussy with a single lunge.

“Oh, fuck yeah!” Megan cried as she arched her back and felt me drive all the way into her vaginal depths.

I blinked twice while hearing my girlfriend’s voice, and then I remembered that indeed, I was fucking my girlfriend and not my little sister. Shaking my head, I dismissed the momentary thought of Brooke and concentrated on the girl currently skewered on my shaft.

I fucked Megan roughly, pumping and driving while letting the fingers of my right hand flutter over her clit. The brunette clenched her butt and bucked her hips, fucking me right back.

Cassidy was whimpering and masturbating herself beside us, scooping out little globs of my semen inside her and using it as a lubricant, rubbing my cream into her own clit. And the sounds of the two girls moaning in ecstasy were all I needed to spur me on even harder.

Megan came first, followed shortly by Cassidy. And I took that as my cue to switch holes. Ever since I’d first popped a finger up Megan’s ass, she’d loved that little extra sensation. But fingers were one thing. My thick cock was something else entirely, and even now I could see my girlfriend wincing in pain as she was stretched open wide. I thought about stopping, but I knew she could take it and Megan freely offered me her ass as an expression of love to me.

Still, even as I watched my shaft disappearing into Megan’s bunghole, I briefly wondered what this would look like going up Brandi’s ass, parting her cheeks and squirting my juices deep into my sister’s rectum.

I tried to regain my focus onto Megan, my loving girlfriend who was doing this solely for my pleasure. But I was too far gone into my lust. The fantasies of Brandi were simply too strong, and I couldn’t help but imagine I was reaming my sister out and pounded my cock through the tight ass harder and harder.

“Oh, gawd, damn, Ben. Fuck me. Fuck me. Take my ass. Take it!”

I took it. I took it hard. And presently I was grunting and growling and delirious with the sight of Megan’s body and the vision of Brandi and then I was there, cumming, blasting wad after wad of heavy cock cream into HER bowels.

I was brought back to the present by the sound of Megan screaming. At first, I worried that she was in pain, but then I realized that her sphincter was clenching around my shaft and her hips were wriggling to get me DEEPER, not out of her. Megan was in the middle of a BIG orgasm.

A pale arm was beneath my girlfriend, and I realized that Cassidy was actually fingering Megan and strumming her clit. And then all at once, Megan’s limbs gave way and we both fell heavily onto the bed, my weight pinning down my girlfriend while my cock was still fully embedded up her asshole, and we even trapped Cassidy’s hand beneath us.

And then there was nothing left but the sound of three people panting. I rolled off of my girlfriend, lest I crush her. Her anus was a gaping hole, stretched wider than I’d ever seen. And Megan and I were both sweating like pigs.

“Holy fuck…” Megan sighed. “I’ve never felt so completely FUCKED in my life!”

“We’re all young, Megan,” Cassidy sighed. “We’ve got lots of time to try and top even that!”

I was a happily sated boy when I arrived for Monday night dinner with the family. I was in such a good mood from my orgasms that I barely even noticed how quiet Brandi still was. But I did notice. And before dinner was done, I’d gone out of my way to engage my older sister in conversation and frequently asked if she wanted a refill to her drink or for me to pass her any particular foods.

Brooke, on the other hand, was giving me the cold shoulder. She was very blatant and obvious about it, and when mom asked what was going on, Brooke just snarked, “Ben is being mean to me.”

The family left it at that. The last thing I wanted was for Brooke to explain that I was mean because I wouldn’t let her suck my dick.

So I focused on trying to reconnect with Brandi. The last thing I wanted was to go through life with two sisters pretending I didn’t exist. And perhaps five minutes before the meal was done, I finally got through to my big sister. She put her hand on top of mine and said, “Hey Ben, let’s talk later, okay?”

I beamed, thinking we’d finally turned the corner. After all, Brandi had given me the cold shoulder about three weeks before, and once we got to talking after that little stand-offish period, we ended up screwing each other’s lights out.

And so I found myself sitting on my own bed, a few feet away from Brandi just to help prove I wasn’t a threat to suddenly attack her or try to rape her or anything. My older sister was still very quiet, and I gave her the extra time to compose herself before we started the conversation.

“Ben, I want to thank you.” Brandi let her hand slide across the bed towards me, and eagerly I slid my own palm over hers, squeezing gently. “Thank you for keeping my faith in you.”

I arched an eyebrow, not yet understanding. “Huh?”

Brandi managed a little smile. “I… I’ve barely slept these past couple of nights. I kept imagining that Brooke had slipped into your room and the two of you were fucking like rabbits. I was horrified at myself for feeling turned on by it. And I was also horrified at the idea that it was somehow my fault that Brooke was crossing the line of incest.”

“How could you be responsible?” I frowned. “Brooke is her own girl and she can make her own decisions.”

“Because she told me, Ben,” Brandi sighed. “That afternoon when she had me teach her the basics of giving a blowjob with the dildo, she told me everything. A month ago, she caught me going into your bedroom one morning when she had to get up to pee. She peeked in through the doorway and watched me giving you a morning blowjob. Before that, she’d never considered doing anything sexual with you. She thought you were handsome, but you were just a brother to her.”

My jaw dropped. How much had Brooke really been watching?

“She caught us fucking another time. She actually watched you ejaculating your sperm into my pussy. She saw it all. And because I seemed to be having the most wonderful orgasms, Brooke started to fantasize about you doing the same things to her. So it IS my fault she’s even thinking of committing incest. If she’d never seen me doing it with you, she never would have thought of it herself.”

I screwed up my face. “You don’t know that. I never learned from anyone but I started fantasizing about you as soon as you grew breasts.”

“You’re a guy, Ben. Of course you drool over breasts.”

I shrugged and Brandi sighed, squeezing my hand. “Ben, Brooke would have had sex with you if you wanted, pill or not. I know she certainly wanted to give you a blowjob. She told me so specifically after I showed her the basics. And when I reminded her of her promise not to try and seduce you or do anything sexual, she just shrugged like she didn’t even remember making the promise. I knew then that she was going to make a play for you. I know what it’s like to be 14 and horny.”

Brandi took a deep breath. “I told you I haven’t been sleeping. I heard Brooke sneak out of her bedroom this morning and go into your room. I stayed in my bedroom, slumped to the floor with my ear to the door. I was already picturing her giving you a blowjob and you cumming in her little mouth. I was already picturing you taking her virginity and giving her the fucking of her young life.” Brandi quivered and moaned in arousal at the image, then immediately started crying with internal shame for her naughty thoughts.

I had to admit, the idea made me hard, even though I knew I shouldn’t be thinking that way of Brooke.

It took a minute, but Brandi composed herself. She sighed and then said with a happy little smile, “But you held up your end of the promise. Less than two minutes after she went in there, she came back out and stomped none too happily down the hall. Still, I had to check. So I went into your room and inspected your prick to make sure you hadn’t cum or put yourself inside her or anything.”

I nodded, remembering how very strange it had been when Brandi walked into my room this morning.

Brandi sighed again, and this time she slid herself over to me so that her hip was pressed to mine. Instinctively, my arms wrapped around her and she hugged herself against me. “You’re a good brother, Ben. Brooke isn’t ready yet. She’s still too young to understand what she’d be getting herself into. Hell, maybe I’m too young to really understand.”

I nodded and stroked Brandi’s back.

“I love you, Ben,” Brandi turned her head up to me with tears in her eyes. “I know I shouldn’t be with you this way, but I want to. It feels too good not to,” she pinched her forehead together wistfully.

I smiled. “Me, too,” I said seriously as I pulled her even closer.

It was so natural for our faces to come together, and then our lips mashed and Brandi sighed happily as we tenderly kissed. It wasn’t an ordinary kiss. It was a kiss of lovers, the kind of kiss we’d been sharing for the past few weeks. I felt a little thrill go through me as I realized that maybe, just maybe, my sister and I would find each other as lovers once again.

The kiss went on for a few minutes, unhurried. We were exchanging more affection and love than lust, and by the time it was over, there were no more tears. Actually, the bags under her eyes already looked like they were clearing and there was a radiance in Brandi’s eyes as she looked at me.

But then that light dimmed. She sighed and looked away, saying “I still think it’s wrong for us to be committing incest.”

“That’s okay. I’ll still love you, sex or not,” I said reassuringly.

“And you won’t do anything with Brooke?”

“Nope. I promise.”

“Good. I know I can trust that,” Brandi said in a weary voice as she got up to leave my bedroom. “And I think I can finally sleep now.”

Tuesday morning I woke up with my alarm clock. There were no sisters sneaking into my room to give me blowjobs, and I was almost disappointed. But I figured Brandi was still asleep and even if she never gave me another blowjob again, I didn’t begrudge her desire to resolve the moral conflict in her head.

After all, I was getting a taste of the moral conflict myself. Brandi’s body wanted to be with me, but something in her head told her it was wrong. Now, my body was instinctively reacting to Brooke, even though my own head told me that she was too young and that it was wrong.

I was disappointed Brandi wasn’t resuming our intimate relationship. But I wasn’t disappointed that Brooke hadn’t made a second attempt on me. I was just relieved. I didn’t want to deal with Brooke and the odd mix of emotions she stirred up in me: that weird combination of lust, guilt, and brotherly affection. I was afraid that if she came to me again, I’d end up rejecting her again and things would get really bad between us.

But Brooke was cheery and smiling as she poured herself a bowl of cereal. And she chatted inanely with me on the drive to school, just like any other day. It was as if she’d never wrapped her lips around my cock and we were able to proceed as if Monday morning had never happened. I had my sister back and if Brandi was feeling the same way about me today as she had last night, I would have both sisters back.

And when I got home, the puffiness in Brandi’s eyes was gone and she gave me a casual hug in greeting. I was delighted and soon I realized that things had truly gotten back to normal. I went to play my video games, Brooke whined that I was hogging the TV, and she tried to manually power off the gaming console. But I was quick to yell and spanked her ass twice before she ran away covering her butt, giggling the whole while.

Twenty minutes later, Brandi simply kicked me out so she could watch some entertainment newsmag.

Yep, back to normal, back to the way things used to be when we were all just siblings and any notions of incest had yet to cross our minds.

Wednesday night, when I walked out after my shower wearing just a towel around my waist, I noticed that the light was still on in Brandi’s bedroom, a pale yellow glow peering underneath the door. It was midnight and I’d been expecting my sister to be catching up on lost sleep by now.

Curious, I went and knocked on her door. Two seconds later came a slightly nervous voice saying, “Come in.”

“Oh, it’s you,” Brandi said with some relief.

I smiled as I poked my head in, but before I could say anything in response I saw that Brooke was sitting on the bed, one leg pulled up beneath her as the two sisters were obviously in the middle of a conversation.

“You still awake?” I asked Brooke in a big-brotherly voice.

My little sister shrugged and nodded her head to Brandi. “We needed to talk. It’s a girl thing, a sister thing.”

Brandi nodded in confirmation and smiled serenely at me.

Brooke continued, “And we’re talking about you.”

My eyebrows went up. “Wait, what about me?”

Brandi got up, took my shoulder, and guided me back out her bedroom door. With a pointed expression, she said, “Good night, Ben.”

I could take a hint. Frowning, I said, “Good night ladies.” And then I went to bed.

Thursday, I was driving myself and Brooke home from school when she said out of the blue, “Ben, you don’t have to worry about me trying to seduce you or anything.”

I jerked the wheel hard enough to make the Camry in the next lane honk his horn at me.

Brooke gave a little grin when I glared at her and she just sighed. “I talked with Brandi. I think I understand the situation better, and I decided I don’t want to complicate things just yet. I HAD thought I could just practice blowjobs and other stuff, and that we’d just be normal otherwise. Puzzles, video games, whatever. But I think I realize now that we wouldn’t be able to be normal. Things have already gotten so weird between us. This sex stuff just… it changes people, doesn’t it?”

“Completely,” I nodded. “You can never go back to the way things were before it.”

Brooke nodded. “I don’t think I want to change our relationship just yet, Ben. I like you as a big brother right now. Don’t wanna mess with that.”

“Good to hear,” I said with relief. I had enough complications in my life as it was.

“But that doesn’t mean I can’t change my mind in the future,” Brooke said with amusement in her voice. And when I arched an eyebrow at her, she merely giggled and then looked out the window.

Thursday night, just past 11pm, I went into the hallway wearing nothing but a towel just after I heard the shower stop running. A few minutes later, Brandi stepped out with wet hair and her towel wrapped around her torso, tucked between her cleavage and just barely falling below her crotch.

Not even bothering to appear surprised, I simply folded my arms over my chest, leaned against the wall, and openly ogled my sister’s nice body.

Brandi rolled her eyes. “You’re such a pervert, Ben.”

“That’s what Megan tells me.”

“Well, she’s right.” Brandi strode out of the bathroom and calmly sashayed over to her bedroom. I turned and followed her with my eyes, and just before she closed the door, she turned her head sideways to see if I was looking.

I was, and Brandi stood there for a long moment, breathing a little harder as she waged some internal war. “We’re not having sex again, Ben.”

“I know, I know,” I nodded. “But can’t I just enjoy looking?”

Brandi just let a little smile creep over her face and she nodded her acceptance. And then she just stood there for thirty seconds or so, letting me drink in her beauty.

I sighed happily, and Brandi took that as her cue that I’d had my fill. She moved her hand to close the door and I prepared to turn away and take my own shower. But with an impish grin, she dropped the towel to the floor, flashing me a wonderful view of her naked back and exquisitely tight ass.

Less than a second later, the door closed. But I allowed myself a happy smile.

On Friday night, Brandi started her shower just like always. And when she emerged from the bathroom, I was ready and in position, leaning against the wall, eager to perve on my sister.

I knew we weren’t going to have sex again; Brandi had been quite clear on that point. I’d even already blown my load tonight, twice, on my date with Megan and Cassidy. But I certainly wouldn’t mind a few more peeks at my sister’s body, or whatever else she’d give me.

After a few minutes, the bathroom door opened and Brandi waltzed out drying her hair with her towel, and the towel she was using to pat down her hair was her ONLY towel. She was otherwise buck naked and automatically my eyes went to her firm breasts and freshly-shaven pussy.

“Hi, Ben,” Brandi flashed me a saucy smile. Her skin was flushed, and not just from hot water.

“Whoa…” I exclaimed in a low voice.

“Nothing you haven’t already seen before…” Brandi’s eyebrows went up teasingly.

It wasn’t, but I still enjoyed the view. Her round tits were pulled high up with her posture and I drooled while looking at the dark nipples and small areolas, remembering what her breasts tasted like. And she even parted her legs to the side, opening up her pussy lips just enough to let me see some pink. The boner in my towel was very prominent by the time she finished with her hair.

And then without another word, Brandi strode confidently to her bedroom. Just before she closed the door, she turned to flash me another view of her naked frontside. And then she winked at me.

I stood in the hallway for a few extra minutes, my heart pounding and my dick obviously tenting my towel. I told myself that the situation was normal. I’d clearly shown a desire to ogle and Brandi had been willing to tease me, even back before we ever became intimate.

I reminded myself that we weren’t going to become intimate again while I fought to get my breathing under control. Then I reminded myself again. And again… It wasn’t easy to do now that I had a fresh image of Brandi’s naked body in mind. It was especially difficult because I still remembered what it was like to have sex with her.

I fought the urge down. I knew I was more than just hormones strapped onto a conscienceless dick. I loved my sister, and the last thing I wanted to do was hurt her again.

But I was still going to jerk off in the shower to fantasies of her.

Everything was quiet when I pulled up and parallel parked on the curb, just another lazy Saturday morning. I was returning home after dropping off the twins at a birthday party being held at the local mini-golf/climbing tower/arcade zone. I was assigned to return home and pick them back up in four hours.

Mom and Dad had left to go for one of their golf outings together. It was only January 20th, still winter. But this was Orange County, and I think Dad just really wanted to go golfing in January so that he could brag to his work associates who lived in places like New York and Chicago that “Yeah, I went golfing this past Saturday.”

There was no sign of my remaining two sisters when I walked into the house, and I headed upstairs for my bedroom. Just inside the door, I dropped my wallet and keys onto the desk and was turning around to go back downstairs when I saw that my room wasn’t empty. Brandi was reclining on my bed, wearing just a thin robe over her panties, and with no bra. Her eyes were locked onto my face while she dug her fingers inside her panties and rubbed herself.

“Holy SHIT,” I stammered. Brandi was gorgeous, her hair pulled back to show off her pretty face and her robe parted to the sides far enough for me to clearly see both naked breasts, capped with erect nipples. My memory filled in all the flesh I couldn’t see, and even her pussy lips made obvious dents in her panties.

“Hi, Ben…” my sister said in a slightly nervous voice. She turned onto one side, propping herself up on one elbow. She was tense, but there was no mistaking the lust in her eyes.

“Brandi?” I asked in confusion even as my feet carried me towards her. “What’s going on?”

Brandi quivered, her eyes drinking in my body while her left hand slid down to her own hip, the fingers dipping inwards to her pussy. “We’re going to have sex today, Ben,” she husked.

My mind immediately went to the last time we tried to have sex. “Uh… where’s Brooke?” I queried.

“At Jennifer Vo’s. I’m sure of it this time. I was there when Brooke called her to confirm. And besides… Brooke promised she would give us the time to do this without interruption.”

I arched my eyebrow at the notion of Brooke giving me and her older sister time and space to fuck.

Brandi took a deep breath and then fixed me with an intense stare. “We’re all alone, and I need you, Ben.”

By now, I’d stepped next to the bed and Brandi reached up to take my hand. I stared down at her face, comfortably ignoring her body for the moment. “Not that I’m complaining, but what happened to ‘We’re not having sex anymore’?”

Brandi sighed and tugged me down until I was sitting on the bed beside her. She pushed me so that I was slumped against the pillows and headboard, rolling onto her side so that she could put one hand on my chest. “I changed my mind. I changed a lot about the way I’m looking at this situation. And part of it was because of my conversation with Brooke.”

“Brooke?”

Brandi smiled and shook her head. “That girl can be so annoying. I’d tell her she couldn’t do something and she answered, ‘Why?’ Over and over again. ‘Why? Why? Why?’” Brandi’s voice took on a nasally, whining tone that got old really fast.

“I realized I didn’t have any good answers. I’m not raping you. I’m not molesting you. I’m definitely not doing anything against your will. So nobody’s being hurt.” Brandi reasoned. “And I’m not a 14-year-old virgin. I’ve had sex before and I’ll have sex again with other people. I know you’re just a fling and I’m comfortable flying away to school and walking away from ‘us’. The two of us fucking isn’t really so different than me stripping for you: both get us aroused and make us feel good. It doesn’t really mean anything beyond that.”

I tried to communicate with my eyes that becoming intimate with Brandi DID mean something to me. It certainly changed my relationship with my older sister.

But Brandi just looked at me with lust. “And besides… I WANT to. I want to feel you inside me, Ben. I want to feel your cum spurting into me. The only things stopping us are my mental hang-ups, and I guess I just decided that I’m hanging myself up over nothing.”

Brandi leaned in and husked straight into my ear. “I WANT you, Ben.” And then she licked my ear before moving lower and nuzzling her nose against my neck. It felt sooo erotic and I felt my skin begin to tingle.

My body was getting ready, but my brain had not yet caught up. True, Brandi had been progressively moving back in this direction with her little flashes and strip-teases of the past couple nights, but I really had thought she would stick to her no-sex boundary. “Are you sure you want to do this? Brandi, I care about you. And I really don’t want to make you do anything you’re going to regret.”

Brandi sighed and brought her wet fingers out of her own crotch, popping the tips into her own mouth as her eyes fixed on me. “You’re sweet, Ben. But the only thing I would regret would be flying back to school having NOT fucked you again before I left. The last time we were together, Brooke interrupted us. I want to feel you thrusting in me, Ben. I want to feel your semen pouring into my body. I can’t help it. I’m totally hot for you.”

“But… What happened to ‘wrong’?” I pointed to my own head.

She took my hand and placed it onto her bare breast. “There’s nothing left but ‘right’.” And then she kissed me.

Any further arguments flew out of my head when she kissed me. Pleasure endorphins shot into my brain, washing all doubt away in a flood of happiness. And all my built-up longing for Brandi from the past week exploded inside me as I urgently wrapped her up in my arms, pulling her tightly against me while I kissed back so hard that I was sure I’d bruise her lips.

When we finally broke for air, I looked deep into my sister’s eyes, seeing her excitement and lust, without a trace of hesitation. My hands went to pull her robe off her shoulders while hers went to the fasteners of my jeans. I looked up and asked, “How long do we have?”

“What time do you need to pick up the twins?”

“Uh, about three-and-a-half hours.”

Brandi grinned. “Then we’ve got 3 hours and 29 minutes.”

We finally separated at around 3 hours and 35 minutes. Yeah, I was late, but the twins would live. Both Brandi and I knew that this was our last time together for the Winter Break, and possibly forever depending on how much we changed over the next few months.

We’d both gotten in the habit of getting regular orgasms for the past few weeks. I’d at least still had my girlfriends for sexual release, but Brandi had been limited to masturbation since last Saturday. And once we both understood that fucking was back on the menu, my sister was ravenous for my cock to be inside her. We didn’t even wait to get all our clothes off. Brandi got my shorts around my knees and I shoved her wet panties to the side, and then one powerful thrust later I was once again buried to my pubes in my sister’s twat.

“Oh, Ben! Fuck me, little brother! Fuck me and fill me up with your cum!”

That first fucking only lasted about five minutes before we both came. She’d been fingering herself for a good ten minutes while I dropped off the twins; and she’d already been on the edge of orgasm. Once Brandi came, the feeling of her spasming pussy muscles pulled me over that edge with her so that I splashed her innards with incestuous sperm.

We rested for fifteen minutes after the hard and fast quickie. We took our time to remove the rest of our clothing before cuddling naked. She talked about how much she would miss me and lamented about how we’d waited to long to become closer as siblings.

Eventually, her soft caresses on my dick started to get a new rise out of me, and my older sister bent over to swallow my dick and bring me back to a full erection. That second time, Brandi rode my cock while draping her tits over my face so that I could suckle at her nipples.

“Mmm… so tasty,” I growled around one boob. “I’d love to see these puppies filled up with milk. What do you think, Brandi? Would you like to see me suckling on this one while our baby drank from the other because I’d knocked you up?”

“Ohhh!” Brandi groaned.

“You like that? You want to feel your brother’s sperm worming their way into your womb to make a baby? You wanna feel that?”

“FUCK!” Brandi jerked and promptly came, her back arching while her hips swiveled around my cock.

When she was done, she stopped moving and panted heavily, her eyes unfocused for a bit before she was able to blink and start calming down. And then without warning, she reached out and slapped my cheek.

“Oww!” I exclaimed and held my cheek.

“Impregnating me,” Brandi scoffed.

“Admit it,” I teased. “The idea turned you on.”

Brandi grinned and then I rolled her over onto her back so I could give her another injection of cock cream, whispering about how my sperm were going to swim through her uterus to her fallopian tubes in search of an egg.

“Do it! Do it!” My sister urged. “CUM IN ME!”

With a grin, I did just that, blasting my incestuous sperm into the back of her womb. And after I filled her up to overflowing, the two of us cuddled and giggled at the naughtiness of our illicit thoughts.

We paused to take a shower and clean ourselves up. I happily soaped up my sister’s private parts while I ground my third erection into the crack of her ass. Brandi moaned and complained, wondering why we never showered together this BEFORE when we had all those nights alone, instead of taking showers in turn.

We didn’t screw in the shower, however. We broke for lunch and then Brandi hoisted herself onto the kitchen counter again, eating a sandwich while I bent over eating her pussy, not stopping until she’d finished her sandwich and also had two orgasms along the way. And then we couldn’t resist fucking on the dining room table, just to see what it would be like.

Like Cassidy before, Brandi felt uncomfortable on the hard, unyielding wood. But her pussy was still tight and I was having no problems. So even though my sister didn’t orgasm that round, I was able to blast her with my third cumload of the day.

We spent another hour in her bed, just talking. I spooned behind my sister while she told me about her upcoming class schedule and what life was like at college. I couldn’t wait to see if the parties were really as wild as I dreamed.

And then to cap off our day together, we moved into a missionary position and I slowly made love to my sister, undulating my hips gently while she held me with all four limbs and tried to pull me even closer.

We’d been kissing for a few minutes when Brandi pulled her head back and leaned it into the pillow while pulling my face down to her neck. Her hips rocked slowly, stimulating my prick without pushing me towards orgasm. And then she said softly, “Ben, I think I know the answer but I just need to hear it again. Will you always love me, no matter what?”

I paused from my thrusting to slowly rotate my crotch, keeping my face directly over Brandi’s. “Of course.”

Brandi chuckled. “Not ‘of course’, Ben.”

I smiled. “Yes. I will always love you. You’re my sister, and nothing can ever change that.”

“Even if we are never intimate again after today?”

I sighed. “I’d be lying if I said I wouldn’t be disappointed. You are amazing in bed, Brandi. But yes, I’ll always love you, no matter what. If we never have sex again, if you never streak in front of me again, if we go right back to being just platonic brother and sister, I will always love you.”

“Good to know you’d still love me even if we stopped fucking,” Brandi leaned up and kissed me tenderly.

She broke for air and then looked up at me with a smile. “But don’t plan on stopping.”

The next day I was assigned taxi duty. I didn’t mind and immediately jumped to help Brandi with her luggage.

“You seem to be getting along much better with your sister,” Mom commented.

I blushed for a moment. If only Mom knew just how much better Brandi and I got along. “Yeah, I think college mellowed her out.”

Brandi snorted. “Little twerp just grew up.”

We both smiled while our mom looked on cluelessly.

On the drive to the airport, there was no sexual tension between us. We’d sated our lust and I found that I was just going to miss my sister’s presence, not necessarily her body (although I would miss that, too). We chatted about nothing the whole way, and the closer we got to the airport, the more excited Brandi became.

“You happy to be heading back?” I asked.

“Yeah, I miss my friends. And believe it or not, I’m kinda looking forward to going back to class. I was starting to get a little bored.”

“What? Bored of me?” I teased.

“No,” Brandi giggled and hit my shoulder.

“Excited to see Brian?” I ventured. “He IS riding with Dayna to meet you, isn’t he?”

“Holy shit! I forgot about that!” Brandi smacked her forehead.

“You DID say he was gonna get lucky tonight,” I smiled without jealousy. I never harbored any thoughts that my sister would be exclusive to each other. What we did was a form of mutual masturbation and affection, not ownership.

The corners of Brandi’s lips went up. “Well, maybe not tonight. I only told him that because I thought I was going to be horny for four weeks straight. But YOU, little brother, took care of that department quite nicely. I’m not sure if I’m ever going to sleep with him and even if I do someday, he’s gonna have to do a damn good job not to be disappointing after the number you did on me.”

I grinned. “Well, if you ever get antsy again, you know where I live.”

Brandi smiled right back.

Fifteen minutes later, I walked my sister up to her gate and waited with her until boarding time. As we heard the announcement over the PA, I turned to my sister while she turned to me, and our eyes met with little twinkles of their own.

What came next was automatic. I sincerely hope that no one we knew was around, because I leaned in, brushed Brandi’s bangs to the side, and gave her a VERY un-brotherly kiss goodbye.

When I pulled away, she smiled radiantly at me and said, “See ya later, alligator.”
