She dug her fingers sharply into Sylvia's neck, wiggling her naked ass, lewdly rubbing her wet, spunky pussy all over her big sister's mouth. Sylvia shuddered with submission, her own cunt throbbing, loving the taste of her sister's pussy in spite of her guilt.

"I'm getting impatient with you, Sylvia. I want you to start licking my pussy right now!"

Sylvia obediently thrust out her tongue, feeling strangely helpless, burrowing it deeply between the hot, pouting lips of her sister's cunt. She glued her mouth to her sticky fuckhole, sucking it, vacuuming the milky cum-juice from the depths of Jill's always-horny cunt.

"That's right," Jill giggled, looking down at her. "You like the taste, don't you?"

Sylvia knew she did. The mixture of pussyjuice and jizz was intensely arousing. She almost felt starved for it eager and willing to suck every trace of her sister's pussy-juice. Her hands slid up Jill's long, slender thighs, clutching the ball-bearing globes of Jill's humping, wiggling ass. Then Sylvia started eating pussy in earnest, sucking and then licking again, sluicing her tongue busily up and down between the swollen, tingling folds of her sister's cunt.

"Ummmm, I'm getting real horny now," Jill sighed. The wanton blonde wiggled her ass in a rotating motion, making Sylvia's lips and tongue push higher on her pussy-hole. "Now lick my clit, Sylvia. Doesn't it feel all hot and swollen? I want you to suck it for me, just like yours. Oh, fuck, I'm getting so horny! Please suck my clit please make it cum!"

Jill dropped one hand, skillfully opening her pussy-folds with her fingers, letting her big sister get at her tingling, pulsing clit. Feverishly Sylvia started licking it, loving the cunt-sucking now, anxious to make Jill cum on her mouth. Jill's clit was large and located very close to her small, pouty-lipped fuck-hole. It probably got more than its share of friction every time a horny guy slid his cock inside her. No wonder her sister craved fucking so much.
