At that moment...
Jill's bedroom was full of sucking and slurping noise, as Jill sucked her brother-in-law's cock. She was eager to bring him up, after all, sisters needed to share and share-alike. When his cock was topped off, she looked at her sister Julie with a wicked smile.
Tony was quickly between the spread of her thighs, running the head of his cock up and down, letting her bubbly juices coat his cock head. Jill was right there next to them, reaching over, and parting Julie's lips with her fingers, holding her lips apart.
"Now that Tony has fucked me, it's your turn now sister! You're so wet and ready for it!"
Julie felt the nudging against her pussy lips, then the glorious feeling as her walls parted, she let out a purr as she felt his cock nudge past the slight resistance, mmmmmm, that wonderful feeling of welcoming acceptance quickly following, that felt so good, as Tony buried 8 inches of stiff cock, not stopping until his balls touched her ass.
Tony pulled back slowly and drove in again, oh yes, that wonderful rhythm of a good fuck starting. Her body responded, she felt her juices start to run, bathing the cock shaft, it felt so fucking good.
She saw her sister looking at her, smiling, then the throbs of excitement shaking her as Jill lifted her leg over her face.
"Now that you've eaten my cunt, it's time for you to eat my sassy ass!"
Jill was facing Tony as she lowered down, she cupped her cheeks and let Julie see her tight little hole. Jill had gone for the full waxing, her tight little ass was as hair-free as her taint and her pussy, and she imagined her sister looking at her, eager for it.
Julie was indeed eager for it, as Tony's 8 inches of cunt pleasing cock was testing the hot liquid depths of her well-heated fuckhole, the idea that she was going to lick Jill's tight sweet asshole at the same time she was being fucked made her eager to please. That tight little pucker, so fresh and clean. It gleamed, as pink and pearly as Jill's sweet cunt, and when Julie lightly ran her tongue around it, Jill moaned deep and low.
"Eat me, Julie, eat my tight little pucker, and I'll do the same to you, baby!"
With that promise of more mind-filling pleasure, Julie eagerly went at her. God, licking her sister's tight little asshole was driving her wild with lust, Jill's moans, gasps, and cries of pleasure adding to the excitement.
"Yes, oh yes my dear sweet sister, play with my pussy while you lick my ass, baby."
Eager to please, Julie drove two fingers up into the wet heat and used her thumb to rub at her stiff, hard clit.
There were three passengers on this orgasm express, and when Julie shoved a wet finger up her asshole, Jill was the first to arrive.
"Fuck, fuck, FUCK, YES FUCK MEEEEEE!"
Jill's voice rose up to a scream of pleasure, and Julie felt the rush of her sister's cum bathing her face, the tight pulsing of her holes milking at her fingers. That took Julie, and as she exploded into orgasm, Tony reached his peak, stiffening up, and letting out a roar as his prick blew his hot load into her sizzling cunt, his grunts and growls of pleasure joining his wife's shriek of pleasure, bathing her deeply with his load.
As they drifted, Julie cooed, "Tony my love, give Jill your stiff cock she can lick you clean, then my sweet sister, Tony's sweet treat is deep inside me, all ready for you."
Julie perched herself on her side, watching. The sights and sounds of her sister eagerly sucking and licking the combined juices of passion off his cock. made her pussy twitch with quickly rebuilding lust, as she cooed, "Yes, that's it, my darling sister, suck it."
