She continues to ride you.

"God!" Alex cries out, cupping her breasts, when she slams her ass down on your cock one last time.

You reach out and caress your hands down her back until you grab handfuls of her ample ass cheeks.

"You're still hard," she grins, looking over her shoulder. "You're a first!"

"Believe me I want to cum but I want to get my hour's worth with your pussy," you declare.

"Hey, if you can make me cum again who am I to complain?" she giggles.

"Challenge accepted!" you laugh. "Turn around, please."

You groan as she swivels on your erection, swinging one leg over you until she faces you.

"Like this?" she asks.

"Yup," you reply and grip her slim waist as you start thrusting your pelvis up.

"Uh!" she grunts and, resting her hands on your chest, lowers herself to counter your thrusts.

You crane your neck up and try to latch your mouth to one of her swinging tits. Alex helps you out, cupping a breast and offers a nipple for you to suck on.

"Ooooh fuck! Uh yeah!" she repeats as she bounces madly on your cock like a child on a pogo stick.

You feel your balls tighten. You don't know how much more you can handle of her riding you.
