Alex gets you to join them

Alex motions to you to her, while John's cock is in her mouth, and then she slaps her ass.

Aha! Foursome action! You walk into the room, get behind Alex, and slip into her pussy as Carolyn licks her clit. John looks up and smiles, giving you a thumbs-up.

You give it to Alex from behind and John fucks her face -- Carolyn's little Asian tongue laps at her clit. Her breasts swing like pendulums from the double fucking. Then you both switch and fill Carolyn, who moans, making her tits jiggle wildly as her body shakes from the double impacts. Alex licks her. You switch back to Alex's pussy and John stays in Carolyn's, and both girls eat the other one. After a few more strokes, he switches to Alex's mouth and you also go for Carolyn's mouth. You notice that the girls are now using their fingers.

Then you both take pussy, you in Alex and John in Carolyn, and you both pound them hard and fast. Carolyn is the first to climax, followed closely by Alex. Their passionate shouts filled the room until you start grunting as you fill Alex's cunt with white lava. John ends with a roar.

Everyone is sucking air, as Alex slides to the floor. You lay next to her, and John lays next to Carolyn. You all just lay there stroking skin and tits and cocks.
