No pussy this time

"No pussy this time," you say firmly, your voice coming out far too breathy and feminine for your liking, even as your soaked cunt throbs with humiliating need, juices slowly dripping down your inner thighs. God fucking damn it... my pussy is literally weeping right now, begging to be bred like a cheap whore, but no. I'm not risking that fertile trap. Ass only. Ass is safe. At least I hope so...

You reach back with one slender hand, fingers still shaking slightly as they wrap around Jimmy's thick, veiny cock. It's rock-hard again, pulsing with heat, the fat purple head already leaking precum. Your other hand spreads one of your own asscheeks, exposing yourself completely.

Your ass is perfect — smooth, toned from years of sports, yet deliciously plump and jiggly. Two firm, rounded globes of soft girl-flesh that feel way too sensitive under your own touch. The skin is silky and hairless, curving invitingly into a tight, inviting cleft. Right in the center sits your cute little pink butthole — a tiny, puckered star, twitching nervously under Jimmy's hungry gaze.

Jimmy’s eyes go wide behind his glasses, his chubby face turning beet red as he stares. "H-holy shit, big bro... I mean, big sis...? Your ass is so fucking nice," he stammers, voice cracking with perverted awe and embarrassment. "It's all smooth and round... like those anime girls I jerk off to. And that little pink butthole... it's so tiny and cute! Looks way too small for my dick... but it's winking at me..."

Shut the fuck up, you nerdy pervert! Don't describe my ass like it's some hentai character! This is so humiliating... My own little brother is drooling over my plump butt like a total degenerate while I'm bent over presenting it to him...

"Fuck my ass instead. It's safer," you mutter through gritted teeth, guiding his fat cockhead right against your virgin pink pucker. The moment the hot, slippery tip touches your sensitive ring, you shiver hard, your firm cheeks clenching instinctively.

Jimmy groans loudly, his chubby hands sinking into the soft-yet-firm flesh of your plump buttocks, squeezing them appreciatively. "Mmmh... so squishy but so toned... fuck, your ass feels even better than it looks. Like two perfect pillows..." He presses forward, the fat head slowly forcing your tight pink ring open.

"Nngh—!! Fuuuuck... slow down, you fat idiot!" you hiss, eyes watering as your cute little butthole stretches obscenely around his thick girth. The burning stretch is intense, every inch of your sensitive anal walls being **** apart by your brother's veiny cock. Your smooth, plump asscheeks jiggle with each shallow thrust as he works more of his length inside you.

Everything feels way too sensitive... even my asshole is betraying me. It hurts but it also feels... good? Fuck, no, this is disgusting. I'm the big brother! I used to noogie this loser and now he's balls-deep in my perfect girl-ass, stretching my tiny pink shithole like it's his personal onahole...

Jimmy pants heavily, his voice thick with lust and shy excitement. "O-oh man... it's so tight... Your little pink butthole is gripping me so hard, sis. It's sucking me in... Look at how your smooth ass swallows my cock. It's all shiny and stretched around me... so lewd. I can't believe my big brother has such a cute, fuckable butt now..."

He finally bottoms out, his heavy balls pressing against your dripping pussy lips, his chubby belly resting against your toned, plump rear. Your perky C-cup tits hang and sway beneath you, nipples diamond-hard. The fullness in your guts is overwhelming — you feel stuffed, claimed, and utterly humiliated.

Jimmy starts thrusting, slow and clumsy at first, then faster, his hips slapping wetly against your jiggling asscheeks. Plap-plap-plap. Each impact makes your smooth, firm buttocks ripple beautifully.

"Ahhn! Hah... y-you're really enjoying this, aren't you, you otaku perv..." you moan, trying to sound angry but only managing a pathetic, aroused whimper. Your neglected pussy clenches hard around nothing, dripping messily onto the sheets while your tight pink butthole milks his cock.

Jimmy laughs breathlessly, one hand slapping your plump right cheek, watching it bounce. "Hell yeah I am! Your ass is way better than any hentai. So smooth... so plump... and this tiny pink hole is the tightest thing ever. Can you feel how deep I am? I'm rearranging your guts, sis~"

This is peak degradation... My little chubby brother is pounding my ass raw, calling my butthole "cute" and "lewd" while I moan like a slut. My body is burning up. My pussy is jealous as fuck. I'm gonna cum from anal... from my own nerdy brother fucking my perfect girl-ass...

His pace turns brutal. Heavy balls slap rhythmically against your soaked cunt as he rails you. Jimmy keeps muttering filthy, embarrassed compliments between moans: "Your asscheeks are so bouncy... fuck, I love how they jiggle... Your pink butthole is stretched so wide around my cock... it's beautiful..."

You bury your face deeper into the pillow, muffling your slutty cries as your orgasm builds fast. Your smooth, plump ass ripples with every savage thrust, your tiny pink ring gripping him like a vice.

"Fuuuck— I'm cumming!" Jimmy groans, slamming balls-deep.

His fat cock erupts violently inside your bowels, flooding your guts with thick, hot ropes of cum. The sheer volume makes your lower belly feel warm and bloated. At the same moment, your own orgasm crashes over you — your pussy spasming wildly, squirting clear girl-cum onto the bed while your stretched pink butthole rhythmically squeezes and milks every drop from your brother's pulsing cock.

So full... he's pumping liters of his thick otaku seed straight into my ass... and I'm cumming my brains out from it... This body is going to completely break me...

Jimmy collapses on top of you, still buried to the hilt in your cum-filled ass, his chubby body pressing you into the mattress. He kisses the back of your neck shyly.

"Best... day... of my life..." he whispers happily.

You lie there panting, your plump, smooth ass still twitching around his softening cock, cum slowly leaking from your abused pink hole.

Forty hours left... How the hell am I supposed to survive this without getting addicted to my little brother's cock?
