"Unnnn, Sis… you're suckin' my fuckin' balls off!"

Melanie gobbled greedily. She wanted every drop of the fantastically delicious cum his cock was spurting into her mouth. Cum splashed against the back of her throat and she gagged. It was coming too fast. It gushed from her lips and nose and drooled down her chin and neck.

"Keep sucking!" Mike yelled, his balls still exploding. "Don't stop!" He dropped her tit, held her head with both hands and slammed his prick in and out of her sucking mouth.

Melanie choked again, but continued, to suck frantically on her brother's jabbing prick. She gulped it down, savoring the exquisite taste. Her hands went to his hips and she slammed him into her mouth, his cock cutting into her throat, hot cum squirting into her stomach.

Mike's legs weakened, his knees buckling. "Melanie," he groaned, stabbing his prick into her hot mouth, "ahhhhh!"

Melanie felt him shudder, then relax. She held his spent cock in her mouth and licked it, sucking the last few drops from his pisser. She felt it shrink and it made her angry. She sucked hard, wanting it big again, wanting more cum to drink.

"Shit, Sis," Mike groaned, yanking his cock from her mouth. "You sucked me dry."

Melanie, her face red, her eyes glowing, licked her lips. "Did you like it, Brother Dear?" she teased.

"Yeah." He heaved a sigh. "Christ, you're great."

Hotter than she had ever been in her life, Melanie stared at his limp prick. She quivered, her eyes drifting to Teddy and his long throbbing prick. "I guess it's time. I got you off, huh?" She winked, her passion making her behave like the whore she pretended to be when she played with herself.

"Yeah," Teddy groaned, his balls aching. "Open your mouth."

Melanie laughed, then tossed back her head. "No!"

The boys stared at each other, dumbfounded, then leered back at Melanie.
