His lips made foam in Donna's cunt as he ate madly into it. Then Donna saw Skip suddenly start coming up Pam's ass, bucking and groaning. His cock raced in and out between Pam's quaking ass-cheeks, then jammed in deep. Donna could tell he was loading his aunt's sucking asshole with cum. Skip's hard bucking against Pam, as he shot his cum up her ass, made her shake more beneath his mother's bare back. Pam began crying out, feeling the jism heat her guts.

"Oh, yes, Skip, darling! Give Auntie Pam a big assful of your cum! Fill my horny asshole up!" she urged.

Donna couldn't help coming, writhing on her sister's back, getting sucked off by her son while he shot Pam's asshole full of jism. She flopped her legs out, clamped them down around Pam's hips, and just let her pussy explode in Skip's mouth.

"Suck Momma's cunt, honey! Suck her off! It's so good! Oh, I'm coming, you little cunt-lapper! Coming! Suck it up!" Donna bleated, her belly jerking up and down in orgasms.

Her furry fuck-hole gushed into he son's mouth. A lot of the pussy-juice ran down the crack of her ass and into her sister's ass-crack. Donna wondered what Pam thought, having all that cunt-juice rain, on her fucked ass, soaking the stiff cock sliding in, and out of her straining asshole.

Donna quivered as Skip kept licking her coming pussy. Then he felt her sister shudder into her own cum, begin jerking her hips up and down. Pam madly squished her asshole back around Skip's spurting prick and shoved her slobbery pussy down around her husband's cock, grinding herself on it.

Pam's naked body jerked in orgasms, every muscle knotted. The pretty brunette gasped to the bliss burning her pussy and asshole, mouth, tits and belly. Her strength was draining out of them all. Even her fat tit-nipples seemed to be exploding. Her pussy squeezed around John's cock, kept spasming with cums.
