Standing up.

You grab hold of the underside of her right thigh and lift it up, exposing her snatch. She reaches up and wraps her arms around your neck, staring into your eyes as you slide your erection into her hot cunt.

"Oh yeah!" Alex moans when the last inch of your shaft is stuffed into her tight pussy. "I love having your big, fat cock in me!"

"And I love having my cock in your tight pussy," you chuckle before thrusting upwards.

"UH!" she lets out a grunt before kissing you fiercely.

You hold her close with your free arm while you kiss her back. You ram your cock in and out of her pussy for what feels like several minutes but luckily before either of you slip and fall from your precarious stance in the wet tub, Alex breaks your kiss to let out a cry of pleasure as her pussy convulses around your shaft.

"Oooh... God..." she moans as she slowly comes down from her orgasm. She looks at you and smiles, "You're still hard?"

"I need to fuck you somewhere else where we won't slip and fall," you grin.

"Where do you have in mind?" she giggles, playfully squeezing your cock with her pussy muscles.
