D-don’t you dare continue if you get close

Still blushing furiously, your cheeks burning hot enough to melt steel, you mumble in a shaky, embarrassed girly voice:

"D-don’t you dare continue if you get close, kiddo..."

Fuck, I sound so pathetic... like a needy little sister begging her brother not to knock her up. My face is on fire. I'm literally lying here with my legs spread like a whore, perky tits out, pussy dripping, while my chubby otaku little brother has just the fat head of his cock inside me...

Jimmy’s eyes glaze over with pure lust. His hands tighten on your smooth thighs, fingers digging into the soft flesh as he stares down at where your tight pink pussy lips are stretched obscenely around the head of his thick cock.

"Just... just the tip, right? I promise, sis..." he mutters, voice thick and trembling with excitement.

But the moment he says it, his hips twitch forward — "accidentally" — driven by overwhelming virgin lust and the irresistible heat of your fertile cunt sucking on him.

SCHLICK.

With one sudden, deep thrust, Jimmy buries every single inch of his fat, veiny cock balls-deep inside your tight, soaking pussy.

"NNNGH—!! FUUUUCK!!" you cry out loudly, back arching sharply off the bed. Your perky C-cup tits bounce wildly as your eyes roll back for a second. The sudden fullness is overwhelming — his thick cock stretching your velvety walls completely, the fat head kissing directly against the entrance to your womb.

OH MY GOD— he’s all the way in!! I told him just the tip and this pervert slammed everything inside me! My pussy is getting wrecked... I can feel him throbbing right against my cervix... This is so fucking dangerous! My womb is literally kissing his cockhead right now...

Jimmy lets out a deep, shuddering groan of pure bliss, his chubby belly pressing against your flat stomach as he bottoms out. "Haaah—!! S-sorry sis... it slipped... your pussy just sucked me all the way in... it’s so fucking tight and hot inside you... way better than your ass..."

He doesn’t pull back. Instead, he grinds his hips in slow, deep circles, stirring your insides while his heavy balls rest against your plump asscheeks.

Your smooth, toned legs tremble around his waist. Your cute pink pussy is stretched obscenely wide around the base of his cock, creaming messily all over his shaft. Just below, your previously fucked pink butthole is still leaking his earlier load, adding to the filthy sight.

"Ahhn! Y-you idiot... you’re too deep... pull out— nngh!" you moan, but your hips betray you, rolling up slightly to meet his grinding.

Jimmy looks down between your bodies with wide, perverted fascination. "Look at that... my whole cock disappeared inside my big brother’s new pussy... Your smooth puffy lips are kissing the base... and your tits are bouncing so nicely every time I move... You’re really wet, sis. Does it feel good having your little brother balls-deep in your fertile cunt?"

This is so humiliating... I’m getting fucked raw by my own chubby virgin brother and my body is loving it. My pussy is clenching and fluttering around him like it wants to milk him dry. Every throb of his cock against my womb makes me feel like I’m going to cum... I’m supposed to last 48 hours without getting knocked up and I’m already letting him stir my insides... What a pathetic big brother I am...

Jimmy starts thrusting — slow but powerful strokes, pulling almost all the way out before slamming back in, making your plump ass jiggle and your tits bounce with every impact. The wet plap-plap-plap of his heavy balls slapping against your leaking butthole fills the room.

"Fuck... your pussy is gripping me so hard... like it doesn’t want me to pull out..." he pants, one hand moving up to grope your soft tit, pinching the stiff nipple. "Can I keep going just a little longer? Just until I’m close... I promise I’ll pull out..."

Your mind is melting from the overwhelming pleasure. Every deep thrust makes your clit grind against his pubic bone and sends sparks straight to your core.

He’s lying... I can feel how much he wants to breed me... and the worst part is... I’m not even sure I want him to stop anymore... This body is turning me into such a cock-addicted slut...

Your breathing turns into ****, slutty moans as another orgasm starts building fast.
