Tommy began to hump through her cleavage. His balls dragged up her flat stomach as his hot cock-meat hissed through her tit-tunnel. His cock-head came squeezing out and ran up her neck, nudging into the fluttering hollow of his sister's throat.

Pre-spunk was oozing out steadily from his parted piss-hole now, laying a slimy trail out of her cleavage and on up to her slender throat.

His preliminary juice was so hot that Belinda thought it might blister her tit-meat. She stared down, watching his knob emerge. Now the tantalizing fragrance of his cock-meat was embellished by the gamey aroma of spunk as she breathed in deeply over his smoking-hot cock.

Tommy shagged up sharply and drew back down slowly. He placed his hands on his sister's shoulders as she held her tits pressed together and he frigged his prick between them, his ass corkscrewing on the thrusts.

His balls were so bloated now that they seemed almost as big as the tits they were bumping against.

"Cum, Tommy cum!" Belinda gurgled, bending her head, her face only inches above the crown of his cock as it slid from her cleavage.

"It's cummin', Sis it's cumming!" he wailed.

"Yeah yeah!" she gasped.

So did her mother, lurking behind the looking glass. The horny woman was as eager to see her son's spunk spurt into her daughter's face as that lewd little mini was to have her brother spray her with slime.

He hammered his prick up through her titcleft. His balls wedged against the lower curve of her tits and exploded as his cock-head pushed out above.

Belinda gasped, feeling his iron-hard cock stalk ripple in her tit-tunnel as his fuck-juice sped up the tube. A thick jet of jism shot from his knob and sloshed against her parted lips. Her jerked back down and another spurt sprayed from his cock-knob on the recoil, skimming along her cheek.
