You ask Alex a question

While laying in bed after a hard fuck, you ask, "Do you remember that first time we fucked over at Carolyn's house?"

"Of course, I do, silly. How could I ever forget when we first hooked up?"

"Well, you said something about Carolyn going down on you?"

Alex punches you in the shoulder. "Oh, you guys are all the same! You want to watch the lesbian action, and then have them both fuck you! The dream threesome! Pervert!"

You can tell she's only mock-angry. "Well, of course. Or foursome, maybe?"

Alex sighs. "Have you talked to John about this?"

"No!"

"Don't." She kisses you hard with lots of tongue and grasps your cock, squeezing and pulling it. You roll on top of her. sliding into her easily, moaning.

Alex's groans, and, after a few strokes, says, "Now you've got me thinking about you and John filling me from both ends, and then watching you stuff Carolyn." She gasps. "Oh, baby, that's good." She pulls your head down to kiss you as you plow her, and she wraps her legs around your back. Her feet urge you to go faster.

She breaks the kiss. "I'll talk to Carolyn and see if she's game. Unh! Yeah! Right there!" She squeals and bucks beneath you. She continues breathlessly, "Then she'll talk to John ... Oh! ... and convince him it was his idea. Oh, fill me up, baby!"

She stops talking and just grunts and moans, because you speed up your thrusts and suck her nipple. You have the best girl imaginable. She's going to arrange a foursome with her best friend and your best friend. You jackhammer Alex with images of fucking Carolyn's Asian cunt into next week.

Alex arches under you and screams in time with your strokes. Her pussy quivers and squeezes you as she comes. Your fantasy of Carolyn and Alex both sucking you off and Alex's spasming cunt make you explode inside Alex's hot body.

The two of you cuddle until you have to leave. Neither of you mention anything more about foursomes.
