Yes. Use her body for your pleasure.

"Your wish," you say, thrusting forward into Jess's sopping pussy, "is my command." You groan the last part and feel Jess thrust back against you as she grips the edge of the tub for support. Her pussy has never been this wet, and you slide in with no trouble, thrusting gently in order to ensure that Jess is ready to accomodate. Jess doesn't seem to be averse to a slow fuck, and she responds warmly, rolling her hips to stimulate you. You groan as you begin responding with occasional quick thrusts, forcing Jess to react with whimpers as she shifts her hands. Your hand leaves her hips to lean forward and grip her right breast. Jess throws her head back as your fingers delicately squeeze her nipples.

Jess does her best to keep up with you, but this has never been a position either of you had practiced, and you can feel Jess struggling to support herself with the tub. You pull out and Jess whispers "No."

"It's ok, baby. Get in the shower; I'm trying to find a position that won't wear us out. Turn on the water," you remind her. Jess immeidately gets the water going, and soon a spray of hot water is covering the tub. You hop in next to her, relishing the warm water hitting your skin. Jess looks at the corner of the tub, where there is an empty space as the tub meets the wall.

"Sit there, and I'll ride you until we're both spent," Jess says, her hand brazenly stroking her pussy. Her other hand points at the spot in the corner of the tub. You lay your naked butt on the "seat," gasping as the cool ceramic hits your skin. Jess giggles but straddles you so that her back is facing you. You feel her warm hand grip your cock and she lowers herself onto you. If anything, she's wetter than she had been earlier. You groan as Jess plays with your balls while gently fucking you. Your hands immediately latch onto her tits, pulling at her nipples. Jess whimpers and she begins fucking you faster, rolling her hips as much as she can. "It feels so good," Jess whispers.

"Your pussy's so wet," you whisper. "What's gotten you so hot?" Jess just continues her fucking, clutching at your hands as you manipulate her firm tits. "Ashamed that you're excited?" you tease. Jess groans and braces herself with her hands on her thighs.

"All of this sex has gotten me hot," she breathes. "I love having this cock in me, John. Please keep fucking me." You respond with more vigorous thrusts, ignoring the splashes of water hitting your face. You slide your hands from Jess's tits to her hips, keeping control of the fucking. Jess's whimpers become rhythmic as you both slide into a pleasurable tempo. Jess begins thrusting with quick shallow strokes, and you can tell from her speedy breathing that she's getting close to climax. You try to thrust deep, your hand reaching for her clit. Jess screams, and you feel her cum coat your cock as you lightly brush her clit and she buries your cock inside her. You try to thrust, but the position has her hips pinning you to your spot. Instead, she uses your hard dick to manipulate her sensitive spots. For someone who's supposed to be pleasuring you, you realize that Jess seems to be worried about getting herself off. Not that you mind, you realize.

"What a cum," Jess whispers. "Thanks, baby. And thanks for the me-and-you time." She pulls your hand to her left tit, and pushes it forcefully into her breast. "You'd just gotten me so worked up that I couldn't go with the bet. I hope you didn't mind." You smile at her, though she can't see it. "Now how about some 'you' time?" Jess slowly slides up your cock, and then, without warning begins bouncing up and down, using her toned legs to ride you. The feeling is amazing, and you hold onto her hips again for dear life. In seconds you shout, your orgasm overpowering you. Jess groans as she pulls off of you, your cock still spurting. Jess stands up, runs her hair under the shower, and as you sit recovering, Jess drops back to her knees and licks all around your cock, looking deep into your eyes. Her tongue bastes your shaft and head gently, and she laps up the cum that isn't in her pussy. She maintains eye contact whenever possible, lapping up both your cum and Jess's.

She finally pulls away, smacking her lips. "All clean," she whispers. "I guess we should get ready for tonight, now." You groan and lean in to kiss Jess. "I love you, John," she tells you after you pull away. "I hope nothing changes how you feel about us."
