Courtney was face down, with her wrists tied behind her back by coarse rope and held by a large hand.  He had spread her legs and arched her back to pull her into his flat belly, the better to drive his cock deep with every thrust.  He was like a machine, driving her slowly to a second monstrous orgasm. The first had come following a warm-up whipping that had left her gasping with pain and arousal. He had taken her on her back with her pussy clutching and squeezing his cock as her pain-enhanced orgasm swept through her.  His cock was long--not the biggest she'd ever had but one that bottomed out nicely against her cervix with an exquisite dose of pain and pleasure.  It was deliciously thick, thick enough to fill her; she felt every inch of him as his cock rasped her hole.  

She concentrated on squeezing his cock each time he drew back as she had been taught, and then opening as he pushed his way back inside.  The process to learn to squeeze and release a cock had been difficult to master, but her training had been...thorough.   It had also shown her how to increase the friction of his cock for her own arousal.  Her labia, when fully engorged were like a second pair of lips sucking on a cock.  

His hand pushed her bound wrists down, forcing her to increase the arch in her back and change the angle of his entry slightly.  His metronome-like pace picked up speed as he neared his climax.  Courtney wondered if he planned to finish in her asshole, but it appeared he was going to take her pussy again.  Her own orgasm was fast approaching as she felt him begin to tense in preparation for unloading inside her.  They didn't call this the breeding position for nothing:  There would be nowhere for his semen to go but her womb as long as he held her in this position.  

With a final thrust, she felt his cum fill her pussy.  The sensation was exquisite, forcing her climax to crash over her body.  She rolled her head and shuddered, her pussy clenching the invading cock like a vise, desperate to extract every last bit of his essence.  He collapsed on her back, grinding her face, breasts, and pussy into the soft mattress, his cock still shuddering with aftershocks as her pussy continued to spasm.  Gradually she came down as his cock slowly softened.   She dozed lightly, awakening a few minutes later as his limp cock slipped slowly out of her body.  

Courtney caressed him as her tits, then her mouth moved towards his cock. She took it inside and cleaned it gently as she had been taught, savoring the taste of her juices mixed with his cum. It started to harden, and he reached for her again. Dodging his hands, she sat up on the bed.

"I'm sorry, but I think that's all I can take" she said with a pout and a smile.

With a satisfied groan, he rolled to the side, sat up and stretched, and released the rope holding her hands. She found his boxers and a shirt in the tangle of clothes near the room's couch and slipped them on. She found his pants and helped, zipping them up while on her knees, and putting on his shoes and socks.

She stood and he reached for her, caressing her breasts and gently tweaking her nipples.

"You were fabulous, I will look forward to seeing you again."

"Thank you, Kind Sir," she said smiling...pleased.

She knew he would rate her performance, and she was sure that he would approve. A bad rating meant correction and pain, something to avoid.
