Take them to the mattress
From Torg Adventure
"Why are we on the floor when we could be on a mattress?" you ask. You stand and pull up the other two.
The girls run giggling to the spare mattress, and Millie strips off Tracy's skirt all the way. They arrange themselves on the bed, holding each other and caressing their breasts. "Come play with us, {firstname}," Tracy says with a big grin.
Millie kisses Tracy deeply, her tongue exploring her older sister's mouth. She plays with Tracy's pussy lips and clit. Then she breaks the kiss and pushes Tracy on her back and spreads her legs wide, her hand rubbing Tracy's clit some more. In a very sexy voice, Millie says, "Come on, {firstname}. Tracy needs your cock. You need to spray full of your swimmers. Breed us for the future of mankind."
Tracy looks at you with a deep lust in her eyes, her hands pawing at her breasts like a prom date. She whines, "I want your dick inside me, pounding me till I come and you fill me."
You climb onto the mattress and the girls kiss you urgently. Two hands play with your cock, and you squeeze a boob of each of them, making them both moan loudly. Then you get between Tracy's legs and run your cock up and down the groove of her sex, making sure to rub generously on her clit. Tracy gasps, pushing her hips up to put more pressure on her cunt and clit.
"Oh, {firstname}, your cock feel so good," Tracy moans. Then she pulls your head down onto her tits, filling your face with her soft mounds.
You line up your cock on her slit and suck hard on her nipple as you slide into her hot, wet pussy. Then you push up from her chest and watch as you penetrate your sister's sex for the first time. She has a look of surprise on her face as you enter her, her mouth open in a silent moan. You shove hard for the last two inches, making Tracy gasp as you hit bottom inside her cunt.
"Oh, God!" she exclaims. "You fill me up with that perfect cock! Now fuck me hard, {firstname}!"
You don't start slowly, like you planned, but you pull back and thrust forward hard and fast, pounding Tracy into the mattress with your strokes. She groans and squeezes her eyes shut as you fuck her.
Meanwhile, Millie divides her time between stroking your back and caressing Tracy's tits. "It's so hot watching my siblings fuck. Having a front row seat for this is the best!"
Tracy says, "I must be an exhibitionist, because having you watch has me so horny, I could fuck a platoon." Then she wraps her legs around your waist and pulls your head down for another deep French kiss. She uses her legs to push her hips and cunt up while your cock quickly descends, piercing her to the core of her being.
You just pound away at her, grunting and moaning.
