"Bare ass?" she breathes, "um, mmmm, um, if I successfully massage your prostate to orgasm you can smack my ass with a belt one time, 5 smacks on my dry bare ass." No wet shower spankings for her thank-you-very-much she thinks to herself, "and only if you finger fuck me at the same time."
"Twice, 15 smacks each time, dry ass and finger fucking goes without saying" he fires back, his thumb still circling her ass, teasingly.
"One session, unlimited smacks" her ass wiggling under his thumb, she knows there was more, what was it, oh right "dry ass, final offer" she blurts out.
"Deal" he says as he pulls his hand away and smacks her ass. He then sets to cleaning her ass and pussy so thoroughly, she's sure it will squeak when she walks!
They reverse positions with his ass pointed in the air and she gently spreads his ass cheeks to soap the area. Massaging his perineum she's rewarded with a low moan from him. She pushes and rubs the area in gentle circles first one way then another with her thumb. Circling his hole with a finger she gently pushes at the edge without penetrating; today was about getting him used to the idea and letting her see an area she's never viewed from that angle before.
Rinsing off the soap she takes a deep breath, leans down and licks his hole; a quick, flickering lick to see his reaction. His ass jerks in surprise, she grabs it tightly and licks again, then she pushes her tongue past the barrier, a slow invasion that elicits another moan from him. She repeats the process, lick, push, lick, push, then she adds in massaging his perineum, drawing her fingers down his scrotum, again and again, pushing a little harder each time and his moans get louder. Reaching between his legs she grabs his now-hard cock and gives it a few, strong strokes before giving his ass a final lick and standing up.
"That's all for today" she starts to say, but she barely opens her mouth to speak when he spins around grabs her and pushes her out of the shower stall, turning her again he bends her over the tub deck and she barely has time to brace herself with her hands before his cock is assaulting her cunt. He slams into her, pulls back and slams in again, this time she's ready and she pushes back meeting him thrust for thrust. Thrilled at this reaction she feels an orgasm building with each thrust. If this is the response to teasing his ass, what will happen when she gets him off with her finger?
He's pounding her pussy for all he's worth, gripping her hips hard to maintain pace, he can't remember the last time he was this hard. Thrusting into her again, burying his cock as deep as it will go, hearing her moans, and cries, his balls tighten up and his cock thickens getting harder and his orgasm spills from him at the same time she grips his cock with her pussy in the throes of her own orgasm. Both of them gasping for breath they remain in that position for a moment, she chuckles softly and says, smugly "You liked."
"mmmmmm" was all he could manage.
