"Jill, stop that!"

But her legs wouldn't obey her mental command to clamp shut. She just sat there.

"Wow, your panties are all wet!" Jill giggled. The blonde shamelessly rubbed her big sister's pussy, expertly stroking her cunt-slit through the sheer panty-crotch. "Oh, fuck, it really feels hot. Wow, Sylvia, you have got a super, super horny cunt."

"Take your filthy hands off me," Sylvia gasped.

But she didn't try to shut her legs. If anything, she spread them wider.

"I think you need someone to suck this horny pussy and make it feel better," Jill purred, in a baby-talk voice. "Want me to lick your cunt and make it cum?"

"No!" Sylvia gasped. "No, this is so awful!"

"Why don't you knock off the shit, big sister?"

Jill giggled as she slid off the couch, kneeling in front of it, reaching up to roughly yank off Sylvia's skirt. The panties went next, leaving her naked from the waist down except for her sandals. Roughly Jill pulled Sylvia's ass to the edge of the couch, pushing her legs wide apart, groaning shamelessly at the sight of her big sister's hot, throbbing, dripping-wet cunt.

"Wow," Jill purred. "Now that's what I call juicy!"

"Oh, no!" Sylvia whined. "No, please…" But by then Jill had already buried her face between her big sister's spread-eagled legs. Lewdly the nympho blonde pressed her mouth on Sylvia's throbbing pussy, moaning with pleasure as she smelled and tasted the heavy flow of musky fuck-juices flowing from Sylvia's fuck-slit. Sylvia trembled helplessly as Jill feverishly began licking and sucking, lapping her tongue greedily between the swollen, hairy folds of Sylvia's cunt.

"Unngghh! No, stop, no… unnngggghh!" Sylvia shuddered as the intense pleasure mounted in her loins, as her furry, drippy pussy responded to Jill's urgent licking. "No, don't do that! It's so filthy, it's… ungghhh! Oh, Jill! Oh, oh… ungggh! Unngggghhh!"
