"Yeah, baby?" Cliff snickered as Barbara's tits bounced up and down with every movement of her body. "Go! Go!"

Cliff held her ass and guided her movements. And Linda watched from the darkened doorway, two big tears running down her checks.

Barbara stopped moving now and Cliff held her hips as he pistoned his cock in and out of her cunt. The blonde pinched and pulled her own brownish nipples, her eyes shut tight as she erupted in an orgasm.

Linda could tell her sister-in-law was having a strong come. The blonde's head rolled back and she moaned deep in her throat. Her entire body trembled and her already puckered nipples got even stiffer.

And then Cliff moved around and the couple was side by side on the bed, their legs criss-crossed like scissors and his cock sliding in and oat of her slit.

"Gonna suck your cunt," Cliff said after a few minutes.

"Oh, yes, baby!" Barbara cried.

Linda moved her hand out of her pussy and crossed her arms over her tits. She thought she and Steve had done everything, but now she knew different. Cliff and Barbara fucked like two totally uninhibited animals.

A tiny moan escaped Linda's lips, but the couple on the bed heard nothing. Cliff was crouching between Barbara's thighs and pressing his face against her wet blonde muff.

Linda watched as he parted Barbara's cuntlips with his tongue and wriggled it around her cuntflaps. He made a loud slurping noise as he began to flick his tongue back and forth over her cunt.

"Turn around!" Barbara gasped. "Wanna suck you too!"

Cliff moved around until the couple was in the classic sixty-nine position. He continued briskly tonguing her twat and now Barbara lowered her lips to his cock, and began licking.

It was too much for Linda. She sobbed as she watched Barbara work her tongue and lips over Cliff's silken cockhead. He tongue-lashed her clit while she slid more and more of his cockshaft into her mouth.
