Afflicted

You plunge into your little sister's bald twat with your impossibly hard cock, her panties still at her ankles and her legs pinned open. She grumbles and moans but she lays still and takes her pussy pounding with rosy red cheeks and a crinkle in her freckled nose. She's so tight but feels so good. You slam forward again and again, overexcited and hyper stimulated. You already feel so close and you know you shouldn't cum inside her. You wouldn't say she's hit puberty but it just feels risky. Lots of girls get their first period by 11 and there's plenty about your sister you don't know.

Trying to play it safe, you tug your sis's tank top up her body, forcing her to wiggle from side to side to help you lift it higher. You tuck it right up to her armpits, just barely exposing the nipples of her flat chest. You graze your fingers across them then run your hand down the front of her tiny torso, all the way down to grab your slick cock as you pull out of her. A few quick pumps and fireworks light up in your brain, your hand squeezing and slinging multiple ropes of cum out over your sister's belly while you spasm in ecstasy.

Of course it's just like before; you haven't softened in the least and as soon as the fireworks stop you feel as fresh and virile as ever. You wipe the cum from the tip of your dick across your sister's puffy vulva then split her lips and get right back to fucking her. She just moans some more as you stuff her full, silently complaining. You have no idea how many times you can do this before you're done, but this curse sure feels like a blessing right now.

You stare down at the half dozen streaks of jizz covering your sister's stomach, one of them resting right alongside her belly button. Even more excited than before, you want to coat her in your jizz. You work her tank top even higher, eliciting some annoyed whines from her. She doesn't seem to mind that you're stripping her, it's more about the fact that she has to help you do it. You have only just got her top past her head, her hands stretched above her, when you know you're out of time. You pull out with a sharp back stroke, buck forward to slap your dick onto her semen smeared stomach, then orgasm without a single extra stroke, your cock twitching as you lean onto your sister's wrists, pinning them down onto the bed. Explosions rock you again and your stiffy spews your seed even further than before, coating the center of her underdeveloped chest right up over her collarbone with a messy attempt at a pearl necklace.

"More?" she asks as you pull her up into a sitting position.

"Uh-huh." You pant briefly as you gain your breath back. "Try sucking it."

Your sis gingerly grabs your meat, clearly put off by this new idea. It's a little slick from fucking her, but you just smeared your shaft and balls through the puddle of spunk on her stomach with your latest orgasm, so now it's coated almost as badly as she is. But she's a trooper and starts a slow jerk after wrapping her slim fingers around your slimy cock. Unfortunately that's not what you asked for. You want her to suck it.

You grab the back of her head and guide her down. She nervously slips your glans into her mouth, her lips just closing around your ridge, the tip of your foreskin tapping the outside of her lips as she jerks you. She sucks on you like a straw but not sure what to do with her tongue. It ends up pressed against your frenulum, rolling gently along your ridge with her active sucking. Does she always do that when using a straw? Her sodas are so lucky. But it's too much for you.

You sink deeper into her mouth as you're overwhelmed yet again, a fresh load of cum cascading over her tongue. She freezes up, no longer jerking you as you flood her mouth, but that hardly matters. It takes a few shots before she tries to pull away. You have just enough of your faculties to hold her in place but she opens her lips and lets you dribble down her chin for a moment before you take one of your hands and help her close her jaw.

"Swallow," you command more than ask, your brain still awash with pleasure. She hesitates for only a moment, her growing sense of panic more apparent by the second, before she squints her eyes and forces back a thick gulp with your dick still resting on her tongue. Her tongue flexing upward as she swallows makes you shudder and coaxes an extra little spurt out of you. She has to swallow once more to get all of the rest of your semen out of her mouth, but once she's finished she manages to relax and open her eyes, looking up at you to seek your approval.

You feel amazing after such an incredible orgasm. You're even about to let her go when a wave of stamina replenishes your body and your cock stiffens back to full form. You feel like you never even came. And here is your little sister with your cock resting in her mouth.

You pull her head down your shaft. She grumbles at first then relents as before. Your sister's panties are still stuck at her ankles as you bob her mouth over your length faster and faster. Everything feels so perfect, like this was always meant to be. You pull her down more and more, but when you start tapping the back of her throat she starts gagging and coughing and asking for air. You pull her off of you just long enough for her to gasp and refill her lungs before slamming back inside her still opened mouth.

It hits you more suddenly than ever. You're really just enjoying it too much. But once you climax you pull your sister down hard, desperate to fit all of your cock inside her. Of course she can't take you. Your spunk sprays out of you while your tip is pressed against the back of her throat. She can't swallow and she can't breath. Three weighty wads of cum burst out of your cock before her sinuses are full. She chokes out one cough and sends two thick ropes of jizz spraying out of her nostrils. You keep cumming and she keeps choking, a second eruption of white goo gushing from her nose a moment later.

Your fireworks haven't quite subsided when you decide to offer your sibling some relief. She instantly gasps and coughs, snorting back more of your cum as some of it leaks from the corner of her mouth.

The sight of your defiled, cum coated little sister should probably disgust you. But instead you seem to be reinvigorated faster than ever. She's still gulping for air, semen leaking from her nose, when you start to jack off again.

"Wh-why... that was mean! I... I'll swallow it if you want. Just tell me."

"Sh-shuddup. Open your m-mouth. Stick your tongue out."

Your sister once again complies, her tongue slowly slipping out into view as her jaw creaks open. She still has cum streaks from her nose down over her lips with several more thin tracks having drooled down her chin. And you're already going to make her taste you again.

You grunt and jerk as you cum as hard as ever sending semen flying towards your baby sister's face. Your aim is atrocious and you end up blasting her forehead up into her hair, then over her cheeks across the bridge of her nose, concealing her freckles with your milky white wad. She's wincing but still has her mouth open expectantly. You lean forward and jerk out a few smaller thinner ropes down the length of her tongue, grunting and panting your satisfaction.

By the time she's squinted and swallowed you're hard yet again.

"See? I promise I'll do it."

You're already pushing back on her shoulders to make her lay down.

"Yeah. I know."

"Do you... again?"

"Yeah."

You press your cock up against her flawlessly smooth pussy and wiggle back and forth to split her lips. You dive straight in this time, making your sis yelp with shock and discomfort. A few gentle thrusts serves as your apology before you jump right back into exuberantly violating your sibling's innocent, angelic little snatch.

Staring down as you fuck her, your sister drenched by your limitless cum, makes you grunt and sneer as you struggle to keep control. You said you wouldn't do it. You didn't want to risk it. But now you're desperate for release, to somehow actually finish. You ball your fists and clench your teeth for as long as you can but you can't hold the dam back forever. With an angry shout, your supernatural testicles swell and pulse and send a new warm batch of your seed hurtling down your shaft and into your baby sis. You fuck her through your entire orgasm, flooding her insides with your seed. And then you keep fucking her once your balls are dry, hoping to somehow stave off the inevitable.

"Shit. God dammit."

You don't even bother slowing your pace. With an instantly refreshed cock you pummel your poor little sis again and again, orgasm after orgasm, completely filling her adolescent womb until your bountiful seed is spurting out past her tight lips with every climax. A pool of cum starts to form under her bum and run off the side of the bed. You cum and you cum but you always need more.

It's only once she complains that she's sore that you pull out, your head filled with confusion and rage. But you can't last a minute before you lift her legs up into the air and slip your perma erection into her cum slickened asshole. This has to stop eventually. You can't stay hard forever. The next one will be the last one, you're sure of it. However many times it takes, you have to get to the end. You'll fill her belly through her asshole if you have to.

You fuck long into the night cumming nearly continuously, again and again, until you have both passed out from exhaustion, your erection still lodged deep within her. Your sister's panties are still hanging from her ankles.
