Bill, his mouth filled with his sister's tit, looked up at her, nodding his head, eyes glowing. No longer nervous, he ran his hand along her side, over her hip, then around to feel her ass. Her skirt had come down a bit, and she lifted it so he could touch her naked flesh. Feeling his sister's round ass, he stroked it, then moved, his palm down to caress her deader thigh, too.

Tracy pulled her skirt up so his cock could touch her bare flesh. She felt his prick smearing juices about her stomach, and adjusted herself so his cockhead was moving through the silky hair of her cunt. She lifted his mouth from her tit and tilted his head, kissing him, darting her tongue into his mouth. Shoving his cock between her thighs, she let her brother fuck through them for a while, holding them tightly about his cock. Holding tightly to her brother's ass, she mewled to the sensation of his hard prick rubbing along the fiery, puffy lips of her wet pussy.

"Hold my ass, Bill," she whimpered, arching her cunt toward him. "Ohhh, hold my ass, baby!"

His mouth was devouring her tits again, going from one to the other, his hips jerking back and forth. Tracy squealed when her brother tightened his hand on her ass, grinding her cunt along the shaft of his cock. One of her hands held his bead, smashing his face against her tits. The sudden orgasm throbbing through Tracy's cunt came as a surprise to her. It bubbled hotly, her clit burning.

"Oooh, I'm coming again!" she yelped, digging at his tight ass. "Oh, Bill, I'm coming again!"

"Me, too!" he yelped, his cock gushing hot, creamy come juice along his sister's thighs and shuddering asscheeks. Spurt after spurt splashed upon her flesh, with Tracy whining in a soft voice, her cunt flexing in searing spasms.
