Rebecca had lapped up all the seepage from Harry's cock-head, and the flushed cock glistened with her saliva. She began to lick up and down the underside of his cock-shaft, gathering up the gooey cream that had trickled down from his piss-hole.

She licked at his balls, then sucked on them. They were bloated with cum, and she moaned, thinking that very soon that cum-load would be hosing her mouth. Lifting the heavy balls with her hand, she lapped at the underside greedily. Then, she ran her flattened tongue up his cock again with a long, slurping stroke, and flutter kissed the underside of his throbbing cock-head lovingly.

"Suck it, Becky!" Harry urged her. His balls ballooned, and he knew he was about to cum. "Take my prick in your fucking mouth, baby! I wanna whitewash your tonsils!"

Rebecca was as eager to drink his jism as Harry was to feed it to her. She kissed the head of his cock, then sucked it between her lips.

Tommy watched his girlfriend's cheeks hollow in as she nursed on another guy's cockhead, and his own neglected cock bucked like a bronco. He was tormented, yet thrilled. He wondered if he was a voyeur. If so, so was his sister, who was staring at Rebecca and Harry with total concentration, and squirming on the seat. Tommy was openly feeling her up now, fondling her plump tits and taut nipples, yet hardly aware of what he was doing, and that he was doing it to his sister. His inhibitions had melted in the heat of his lust.

Rebecca's sweet lips were collaring Harry's cock just below the knob, turning outward as she sucked ravenously on his cock. His long, thick cock stood out between them, spanning the gap between her mouth and his balls.

The fat vein pounded up the underside of his cock, and his cock-head flared in her lips. His cock pumped in and out. Jism was trickling onto her tongue steadily, heralding the massive load to follow, driving her wild with the succulence of his cream.
