The old wooden farmhouse was dead quiet except for the low hum of the box fan in the corner. Grandma and Grandpa had turned in hours ago, their bedroom door shut tight at the end of the hall. Jake and Amy were sprawled across the big queen bed in the guest room they always shared during summer break, the only light coming from the old TV on the dresser.

They’d waited all day for this. The movie they’d picked was pure filth—some high-budget porn disguised as an “erotic thriller.” Tits bouncing, pussies getting pounded, and right now, on screen, a busty blonde was on her knees slobbering all over a thick cock, loud wet sucking noises filling the room.

Amy was only wearing one of Jake’s old t-shirts and a pair of tiny pink panties. Her smooth, tanned legs were stretched across his lap, and she kept shifting, pressing her thighs together. Jake could already smell her— that sweet, warm scent of her pussy starting to leak.

On the screen the girl moaned around the dick, spit dripping down her chin. Amy’s breath hitched. Her little hand slid up Jake’s thigh, fingers brushing the growing bulge in his basketball shorts.

“Fuck... look at her suck it, ” Amy whispered, voice already husky. “She’s so sloppy... I love that sound.”

Her fingertips traced the outline of Jake’s cock through the fabric, feeling it throb and swell under her touch. She bit her lip, eyes glued to the TV as the blonde gagged and slurped louder.

Jake smirked, voice low. “You getting wet already, little sis?”

Amy didn’t answer with words. Instead she squeezed his cock through his shorts, giving it a slow stroke. Her other hand slipped under the hem of her t-shirt, cupping one of her perky little tits and pinching her nipple. A soft whimper escaped her.

Without breaking eye contact with the screen, Amy swung her leg over and straddled Jake’s thigh. She started grinding slowly, pressing her panty-covered pussy right against the hard muscle of his leg. The thin cotton was already soaked.

Jake could hear it—the soft, wet squelch of her pussy lips sliding against the fabric as she rocked. “Mmm... you’re fucking dripping, Amy.”

She leaned down, lips brushing his ear. “I can’t help it... that blowjob scene always makes my pussy throb. I want to be that sloppy for you.”

Her hand dove into his shorts and wrapped around his bare cock. She gave it a firm squeeze, thumb swirling over the leaking tip, spreading his pre-cum around the head. Jake groaned as she started stroking him—slow, tight, twisting her wrist just the way he liked.

Amy’s hips moved faster. The wet squelching grew louder, obscene little noises every time her soaked panties dragged over his thigh. She was practically humping his leg now, little gasps turning into needy moans.

“Jake... touch me, ” she breathed, guiding his hand between her thighs.

He didn’t hesitate. His fingers pushed the soaked crotch of her panties aside and slid straight into her tight, dripping slit. Two fingers sank in easy—her pussy was molten, silky, and so fucking wet it made an audible schlick sound as he pumped them in and out.

“Fuuuck, listen to that, ” Jake growled, curling his fingers against her g-spot. “Your little pussy is talking to me.”

Amy’s head fell back, mouth open in a silent cry as he finger-fucked her harder. The wet, filthy squelching noises filled the room, louder than the movie now. Her juices ran down his wrist, soaking the sheets beneath them.

She pumped his cock faster, twisting her fist around the swollen head, using his own pre-cum to make it slick and noisy. Shlick-shlick-shlick. Her small hand looked so tiny wrapped around his thick shaft.

“I need it, ” she whined, voice breaking. “I need your cock, Jake. Please...”

Jake yanked her panties down her legs in one rough motion. Amy kicked them off and immediately climbed on top of him, straddling his hips. She grabbed his cock, lined it up with her dripping entrance, and sank down in one smooth, greedy motion.

The wet squelch as her pussy swallowed every inch was loud enough to echo off the walls. Amy’s eyes rolled back, a broken moan spilling out of her.

“Oh my god... so fucking full, ” she gasped.

She started riding him hard—bouncing up and down, ass slapping against his thighs. Every time she slammed down, her pussy made the nastiest, wettest sounds: schlick-schlick-schlick-squelch. Creamy white girl-cum coated his shaft and dripped down his balls with every thrust.

Jake’s hands gripped her tiny waist, helping her bounce faster. “That’s it, baby sis... ride my cock. Let me hear how wet you are.”

Amy leaned forward, tits bouncing in his face, and started grinding her clit against his pelvis. The new angle made her pussy squelch even louder, sloppy and obscene. She was creaming so much it was running down his balls and soaking the sheets.

“Fuck me harder, Jake, ” she begged, voice all breathy and desperate. “I want to feel you in my stomach.”

He flipped them in one quick move, pinning her beneath him. Amy’s legs wrapped around his waist as he drove into her deep and hard. The bed creaked, headboard banging softly against the wall. Every thrust produced a loud, juicy squelch as her soaked pussy took his cock to the hilt.

Amy’s nails dug into his back. “Yes—yes—fuck your little sister’s pussy! I’m gonna cum—”

Her walls clenched around him, pulsing hard. Jake kept pounding, the wet slapping sounds turning into a constant filthy rhythm. Amy came with a muffled scream, biting his shoulder so she wouldn’t wake their grandparents. Her pussy gushed, squirting warm girl-cum all over his cock and thighs.

Jake didn’t stop. He fucked her through it, chasing his own orgasm. The squelching was nonstop now, her pussy even wetter after she came.

“Gonna fill you up, ” he growled against her neck.

“Yes—cum inside me, Jake! Breed your little step-sister!”

With a deep groan he buried himself to the balls and unloaded. Thick ropes of cum pumped into her spasming pussy, so much it started leaking out around his cock with every final thrust. The wet, creamy sounds were absolutely filthy as he kept slowly pumping, pushing his load deeper.

They stayed locked together, panting, his cock still twitching inside her overflowing cunt. Amy kissed him slow and dirty, tongue sliding against his as their mixed juices dripped onto the sheets.
