Can't Resist

With his sex drive in full control, Adam smiles and grabs his sister by her ankles. He pulls her close to him, his raging cock pulsing above her wet pussy. He holds her legs up and apart, positioning his head at her lips.

"Sorry, Gwen," Adam growls, "But I'm gonna fuck you like I own you." Adam wastes no time in pistoning in and out of his younger sister. He wasn't gentle and didn't start slow. Just slam after selfish slam to quell his taboo lust.

Gwen didn't say a word. She was in ecstacy. The way he treated her, the violation, the ****, it all pushed her to the edge of climax and flung her over the side. In just a few aggressive thrusts, Gwen was creaming over her brother's dick.

Neither of them cared for the other's pleasure. They only wanted their own.

Gwen wrapped her legs around Adam's waist and pulled him further into her. She matched this to his thrusts and roasted her hips to grind on his cock head reach time it scraped in and out of her.

Adam lined down at Gwen and engulfed her tit in his mouth. He sucked and but down on her nipple, drawing out animalistic screams of pleasure from his sister. In return, she acreage at his back leaving bright red marks up, down, and across his back.

When the pain became too much, Adam straightens up and turns Gwen over. He didn't pull out, just turned her until she was **** into all fours. He grabbed a fist full of Gwen's hair and pulled, arcing her back.

He looked down, his vision completely tinted pink, and saw his sister's jiggling ass. Without hesitation, he struck one cheek with his bare hand. Gwen squeaked. He struck the other one, harder. She moaned.

"You're such a slut, Gwen." Adam said with a smile. "You wake me up with a blowjob, -slap- you swallow your own brother's cum, -slap- then beg for him to fuck you. -SLAP-

"Yes, Adam," Gwen has tears in her eyes from the pain and a moan in her voice from the pleasure. "I'm your slut, -uh!- I'm a slutty little whore for- mhh!- for my brother's cum, -ah!"

"You're gonna get it, little sister." Adam grabs Gwen by her reddened ass cheeks. "You're gonna get all my cum in your slutty, whore holes!" He gave one, violent thrust. He exploded inside Gwen.

Gwen's eyes rolled back and she gritted her teeth as the sudden hot liquid splashed inside her. Her mouth hung open in a silent scream before she collapsed onto the ground again. She passed out from exhaustion in seconds.

After he was finally spent, Adam fell backwards onto his bare ass. He didn't even notice the cold floor as the pink haze dissipated from his vision. He blinked twice and looked at his **** sister. He saw her naked, sweaty body sprawled on the floor. Her ass was as red as her cum leaking pussy. Realization dawned on Adam just as his vision blurred.

"I'm s-sorry, G-Gwe-." Was all he could say before he, too, passed out on the floor.
