"Wanna?" she chirped.

"Yeah!" Tommy enthused.

The nubile girl dropped down on all fours, her head lowered almost to the floor and her trim, curvaceous little ass hiked up to the highest point of her posture.

Tommy knelt behind her ass.

Placing his open hands an her ass-cheeks, he pulled the smooth globes open, exposing the puckered brown bud of her tight little shit-hole.

His cock was already oiled and lubricated by her saliva and he bent down and began to lick out her asshole, getting that tiny slot ready for his reamer.

Belinda squirmed happily, shoving her ass back, enjoying having her brother rim out her shit-slot. He slobbered and slurped in her tight ring for a few minutes, juicing her up for his plundering prick.

As she watched them through the one-way mirror, Jenny was fingering her own asshole, wishing it was her son's cock buggering her. Then she licked her finger, pretending it was still Tommy's cock and that it had just come to her mouth out of her daughter's asshole.

Her cunt was creaming time and again, but she just couldn't get satisfied on her own hands, her voyeur's lust making her insatiable in her cunt and ravenous in her mouth.

Tommy gave his sister's asshole a last slurp, then rose up and moved in closer. His cock angled up, pressing into the crack of her ass as his flat belly rested against the curve of her cheeks.

He humped, stabbing his cock up and down through her ass-cleft just as he previously had pumped it through her smooth tit-cleavage.

His cock-knob loomed out over the small of her slender back and his balls dragged through her creamy crotch. She shoved her ass back, grinding against his loins.

Tommy frigged his cock-meat through the crack for a few moments, then he drew slightly back and biked his own ass up so that his cock was no longer angled upward but was pointed directly at her tiny little asshole.
