She thinks this should be okay. Being comfortable in your own skin, in your own home. Is she really that wrong? I mean, what was I really upset about before, if not being able to do the same until she moved back in. Maybe big sis was right.
But as I tilted my head to reply to her, the little brother in me who’d always looked up to his big sis, wouldn’t let me turn to look right at her pussy again. “You’re right. I guess I didn’t think of it that way, sis.”
“No one does, bro, until they do,” she chirped back with pep. “But I guess, I can’t blame you for coughing up half your cereal– not everyone expects an eye-full of their sister’s pussy for breakfast!” She began laughing again.
I laughed along slightly nervously, “I guess it’s not as bad as a mouthful!” wondering if that was the right response. Her fit of laughter doubled up, putting me at ease. I joined in, turning to see she was actually clutching her gut, laughing. Her legs actually blocked my view of all of her lower parts, but somehow this was nicer than the more explicit look I’d gotten before– the big sis I’d always joked with growing up, was back on the family couch, laughing at one of my jokes. And damn if she really wasn’t a grade-A babe.
I don’t know how I hadn’t really let myself notice it before. Marissa could be one of those Onlyfans models making beaucoup bucks with strip teases, or a fashion model on the fronts of magazines if she wanted to. She kept herself in firm, petite shape with almost no effort, had a natural sense of style, and she had that blonde hair-green eyes combination that drove me nuts like no porn star could.
And here she was, right in front of me, busting a gut to one of her little brother’s jokes.
My hands leapt for her sides just like old times, before she’d left for college. My fingers knew exactly where to find her old ticklish spots.
Marissa shrieked as she realized the tickle fight was on!
My fingers, at first attacking her ribs over the silk nighty found themselves between the fabric and her bareskin as our rough-and-tumble battle moved from one corner of the couch to the other.
“OH MY GAWD, JAKE!” Marissa laughed as she tried fending off my tickle-assault with her elbows and legs.
It was probably on accident, but she kicked me right in the jaw, and before I could think straight, wrapped her legs around my torso, pulling me onto the couch with her.
“Your Turn, Little Brother!!” She laughed confidently as she twisted on top of me. One of her straps had fallen off her shoulder, threatening to reveal one of her pert little B-cups, but before I had a chance to wonder further, her nimble little fingers began tickling my own exposed sides.
It was a lot like old times, finding myself suddenly victim to my older sister dominating me in a tickle fight– I couldn’t quite stop her from tickling one of my exposed spots before she found the next one, and unfortunately, I was just as ticklish as she was.
I kept trying to inch backwards on the couch to get out from under her bodyweight, but she was doing too well at keeping her legs half wrapped around my hips. Maybe that was the reason, or maybe, it was me trying to inch back on the couch to get away from her, but my shorts slipped past my hips before I even noticed they were a problem.
Marissa was way too keen to keep the advantage in our tickle fight to notice my exposed member and kept lifting & inching her leg-locked hips up my own until–
-POP-
We both looked down at where our hips met.
There hadn’t actually been a literal Popping noise– but there may as well have been: my little brother dick was almost completely ensconced in my big sister’s pussy. There was maybe an inch and a half of me still not quite lodged in Marissa’s cunt… kind of moot in the grander scheme of things.
Marissa looked up at me, her mouth half agape, face flushed, tears welling up in her eyes. I’m sure the look on my face must’ve been similar. Except I wasn’t about to cry.
“ohmygod, Sis!” I whisper-shouted! I started to lift my left hand to her chest to help push her backwards, off her brother’s cock, but she caught my hand in hers.
“Shit-Jake! D-d-don’t move, please!” she whimpered, nearly squeezing her eyes shut. I couldn’t tell if it was pain or pleasure or anger or disgust in her voice, but she was clearly shocked.
My eyes darted back to where our siblings parts were joined. I was inside my sister’s pussy! My dick was inside an actual vagina for the first time– and it was my SISTER’S!
That fact was blaring at maximum volume in my head as I glanced back at the illicit bonding taking place at our crotches. So much so that I almost didn’t notice the blood starting to show around her netherlips, on my shaft.
Blood! My mind was worried about a whole new crisis for a moment before I put two-and-two together.
“Ohmygawd sis, are you okay! You’re not a virgin also, are you? I thought, I thought that–”
“Shut Up, bro, oh-my-gawd-this-is-soooo-Wrong!” She half whimpered at me, finally looking me right in the eyes again, biting her lip. “I fooled around a fair amount in college doing other stuff, but never actually… well.. it doesn’t really matter at this point…” she sniffled. She dropped her gaze, and I felt what must’ve been a couple tear drops land on my abs.
Shit– I had accidentally taken my sister’s virginity. What the actual Fuck. While losing my own?! This was SO Messed up! And yet my cock was raging harder than it had Ever been! I was sporting my most massive hard-on ever, even though I could literally see my big sister’s hymen blood around my shaft… This was going to take So much therapy.
Time seemed to slow down to a halt as we both remained motionless on the family couch. My show droned on in the background, unheard. Both of us were breathing and trying to figure out what our bodies were supposed to do in this predicament.
With one last sniffle, my sister lifted her gaze to lock eyes with me again.
“Jakey, th- this is so Bad, what’s happening right now!” she said, urgency behind her words.
“I know, sis! I’m-So-Sorry-it-was-a-Complete-accident-I-SWEAR!” I rattled off in a nervous flurry.
“Me too!” She interrupted. “We, we need to, uhh…” her voice trailed off, as I felt her vaginal walls undulate up and around my shaft.
I’d never felt something so perfect.
I knew my dick felt good when I was beating off, or when my ex would lend a hand, but How can you explain the first time you feel a vagina mould itself around your cock, and ripple its pleasure into your own.
I almost came right there! Inside my own sister’s pussy. It wasn’t even the thought of our incest that stopped me– it was some deeper imperative to not cum before my partner.
As it was, I definitely felt a half-load of precum churn out of my shaft. ‘Shit! Can precum get a girl pregnant?’ my shoulder angel tried shouting.
My big sister leaned forward and locked her mouth around my own in a passionate full-on makeout kiss before I knew what was happening.
I was definitely kissing the woman on top of me back with a fiery passion! My hands suddenly clasped behind her, our mouths our lips our tongues intertwining and parting only for a moment as I wrenched her nighty up and over her head only for our lips to realign into each other angrily. Who was this passionate succubus mounted atop me??
‘YOUR SISTER!!’ My conscience shouted back to my hormone-addled libido.
I pulled my face back from my sister’s, wide-eyed. She was panting, huffing as badly as I was, her face flushed and splotchy. Emotions raced across her eyes, her cheeks, the corners of her mouth.
“UgghhhHH!” she moaned, as her vagina rippled around me again, and then again, and again upwards more rapidly! Marissa’s back arched dramatically, her head thrown back so violently that I felt her long hair hit my legs.
‘Your sister is cumming on your dick,’ the back of my head noted absently.
I was able to start getting a hold of my breathing, and start organizing my thoughts as Marissa began to come down from her orgasm.
And then I realised how pristinely hard my shaft was. It was twitching inside big sis.
She was definitely spasming around me, simultaneously. But my cock was twitching, and I was fairly positive it was because I was in danger of blowing.
In danger. In danger? How could there be danger right now, when my body felt Better than it ever had??
Sister! The cunt you’re inside is your big sister’s! Your blood-related sister is sitting on top of your shaft!!
Is big sis on the pill?!
“Sis! Marissa!! Are-are-are you on the p-p-pill?!” I stammered, trying not to let my perverted thoughts get away from me.
Her hands dashed from my shoulders (when did they get there??) to my face.
“No, I’m not! And Jakey! You CAN’T cum inside of me right now– this is a Really bad time of month for me!!” she pleaded, locking her green eyes onto my own.
I don’t know what other choice I had– I knew she was right. She was DEFINITELY right! Brothers DON’T cum inside of their sisters.
“I love you, sis,” I told her, our eyes still locked.
“I love you more, little brother,” she whispered, her pussy clinching when she said brother.
And that’s when I came inside of her, my eyes and mouth widening into a silent gasp.
Her pussy began clinching again desperately a slit-second into my own ejaculation. “No, no, noooOO!–AHHH-YESSS!”she screamed up to the living room ceiling again, before looking down at her little brother, mounted below her.
My shaft surrrrrged jet after jet of virile jizz into my older sister’s fertile vagina. It was hard to tell how long our orgasms took… was it minutes or an hour? My breath started coming back into my focus. Marissa was still perched atop me, but leaning back onto her propped up arms. I noticed my shaft was softening rapidly, and Marissa’s vagina had stopped pulsing so much.
