"You want it, you'll get it," he whispered, chewing on her tits. "By God, you'll stay fucked after today!"

He began ramming her so hard, her head smacked against the headboard. His balls slipped up and down her thighs, almost grinding into her shitter as he penetrated deeply into her cunt.

Gina's eyes were glazed over, her mouth slack. A low growl of a moan escaped from her lips in a hiss as Paul slammed his full weight into her crotch. Robin didn't think it was possible to live through such a tremendous, brutal assault.

"Oh God, don't ever stop!" Gina grunted, each word punctuated with a raspy moan. "Fuck me for a million years!"

Robin turned her attention from Gina's face to Paul's ass. His tight ass cheeks bobbed back and forth with such speed and force, she could almost feel the thrusts from where she was standing. Then all at once, he too, froze, his body ribboned with the outlines of his taut muscles.

"Oh shit, baby, take it!" he grunted, slamming upward, moving the girl up the bed with his power. "Take every fucking, hot drop in your guts!"

Even from the distance, Robin could see the base of her brother's cock begin to jerk and throb. His cock seemed to grow even larger, thicker.

"Oh, that's so good!" Gina moaned. "So hot and creamy!"

Robin saw a thick trickle of milky sperm splatter out of Gina's cunt and ooze onto her brother's balls. It looked so rich and creamy it made her throat burn with desire to taste it!

"Uuuuuuuhhh!" Paul groaned, jamming the last of his load deeply into Gina's cunt. "Oh baby!"

Robin's fervor only increased when she saw her brother grind the base of his prick against Gina's cum-stained pussy opening. But her excitement grew tremendously when she saw her brother pull away, his cock flopping deliciously against his stomach. Thick wads of cum covered his prick, reflecting the light in the room.
