As she'd gotten the easy one out of the way...

She retrieved her brush and scoured your flesh clean a second time, as you reveled in the afterglow. After she finished, she pulled you out of the tub and toweled you dry, giving careful attention to your softening and then hardening cock, before she pressed you back down on the carpeted floor. She lifted a large jug off the table beside the tub. Your muscles tensed as you prepared to roll away, to strike back, taking her out if she attacked, but all she did was pour oil over your stomach and place the jug back on the table. Strong hands massaged the oil into your stomach, then up over your well-muscled chest. She was using her hands, arms, even her tits to rub the oil into your skin. She went down, reviving your cock and coating it in a shiny, almost glowing oil. She continued down, rubbing the oil into your legs.

By that point, her own naked body was covered in sweat smelling oil as well and you were plenty hard. Commanding liquid syllables dropped from ruby lips, before she slid up your slick body and kissed you firmly. Her firm breasts were pressed against your chest for a long moment as you grabbed her head, feeling silken hair under your fingers as you kissed her rather more thoroughly. She smiled against your lips, before rising astride you and grinding down on your cock, like a dancer, before she lined your hard prick up with her cooch and drove it deep into her with a single, enthusiastic bounce.

She moaned loudly as her tight, wet box was filled with your cock. It was much like fucking a human woman, but she’d had many more years to learn tricks of muscle control, so the walls of her cunt rippled, squeezed and sucked on your dick like she had a couple of tongues in her cunt. Your strong hands rested on her velvety hips, resisting the urge to control the riding she was giving you with some difficulty. Her breasts bounced above you, as she rode your cock, taking it in long, slow strokes that drove her rapidly towards her own orgasm. As you resisted taking control, her hands were helping her grind out her own orgasm on your cock, twisting and pinching her nipples, frigging her clit and generally doing everything she could to get herself off, quickly, though not quietly as the unpronounceable words slipping from her mouth were coming more quickly and louder as she rode you ever closer to her own orgasm. Interspersed between words you didn’t understand were moans, groans and gasps you certainly did, as you were producing your own cacophony under her cunt’s tender ministrations of your so-sensitive cock.

She beat you to the orgasm, screaming loudly as her bouncing became wild and she rode it out on your throbbing member. The muscle contractions that had been so controlled ran rampant, squeezing your cock so tightly it actually hurt for a moment. She stopped, frozen, atop your cock, hands resting on your chest, barely staying upright, as your own orgasm approached…
