Nobody had ever done this to her before and the effect truly took her breath away. Something about that bite on her shoulder hit the nerves deep in her pussy. Different from the effect her nipples had on her clit, it made her whole vagina quiver. That coupled with his hands treating her nipples so torturously made her pussy physically drip down her legs. Her knees were weak, and she thought she might cum right there. Her body started to shake with anticipation.
Right then, he stopped biting and moving. She opened her eyes and could see him looking right at her reflection. They were looking at each other without looking directly at each other. "You have a new rule my pet," he said. "From now on, when you and I are together, you are not allowed to cum without permission. You must beg. And when you beg, you had better be ready to cum as soon as I tell you that you can. Do you understand?"
"Oh fuck!!!!" she thought. More rules and she knew instantly that he would torture her with them. The whole week had been about this. Making her practice withholding. He wanted to control her every action and now he would control her orgasms too. It seemed so unfair. She wanted to scream "HELL NO," but knew he would only accept one answer. "Yes sir. I understand." She basically whimpered this while wanting him to continue with what he had been doing.
"And remember, you beg your Master, you answer your Sir," he instructed and then resumed biting her shoulder and rubbing her nipples.
"Huh?! What the fuck did that mean," she thought for a brief second before the pleasure overtook her scrambled brain. She couldn't process correctly and she could only contemplate wanting sweet release! She needed it. Her hips ground against his cock wedged between her ass cheeks.
His hands started to squeeze and massage her tits and pinch from light to painful, but he never stopped biting and grinding the tender shoulder flesh between his teeth. Finally, his right hand started to travel down to her pussy. She trembled with expectation. She spread her legs before the hand arrived and his finger split her soaking wet lips and pushed in an inch before drawing up to her clit, circling and pressing it. It took mere seconds before she made her first request, "May I cum sir?" She felt so lost in the euphoria of the moment.
His left hand pulled away from her breast and he shifted enough to the side to slap her left ass cheek hard. The sharp impact shocked her into opening her eyes and looking at his reflection again. His other hand came up and grabbed her throat. He held it firmly, but didn't choke. Three more hard spanks. Her ass grew hot quickly and she could only wait for an explanation, confused. "You beg your Master. You answer your sir," he repeated somewhat slowly drawing out the words. He resumed the treatment from before. This sudden shift took her a moment to recover, but within a minute or two she fell back into the same euphoric zone.
"Please may I cum Master?" she begged, almost pleading.
"No," came his simple answer while he continued to tease and play with her body, chewing on her neck again.
Her body wouldn't stop shaking and grinding. She could feel the orgasm swelling in her belly. She panicked with fear that her body would betray her. When it felt truly imminent, she desperately warned, "I can't stop it sir. I'm going to cum. I…have to cum. Please Master! Please let me!! Please Master!" she begged with her whole heart. Her insides were in turmoil as she tried to resist every impulse in her body.
Then he grabbed her by the hair in that way that he did. She didn't really know how he did it so easily. His fingers wound themselves right at the base of her hair at the scalp. He had total control of her without really hurting her. It pulled all of her hair equally at the same time. He pulled her to the bed like a rag doll, sat down, and pulled her across his lap.
He sat at a little bit of an angle at the edge of the bed so she could bend at the waist over his lap with her head turned and flat on the bed and her feet dangling to the ground. His right hand now free, it came down again and again on both ass cheeks. The intense pain made her want to scream despite her best efforts to stay calm. "You only cum when I tell you, you understand!?" She knew he had asked rhetorically and didn't answer and suffered through another half dozen spanks.
Then he stood her up. He reached into the bed side table. He pulled out the cuffs and put them on her while she lifted her legs and arms obediently. Next, he pulled out a larger thinner cuff and put it around her neck and fastened it. It held close to the skin without being tight enough to make it hard to breath. It had d-rings like the other cuffs. To Sarah it felt like a dog collar. For all she knew, it could be. She felt more and more like a true pet to her Master.
Next came nipple clamps. He secured them tightly to each nipple. She sucked in a deep breath with them fully attached. They were already hurting her very oversensitive nipples. There as a long thick string attached to the middle of the chain. She didn't know it's purpose, but didn't have much time to consider. He pushed her forward over the bed. The clamps twisted her nipples more as her tits were pressed into the bed and sent new levels of pain through her body.
She felt lube slide down the crack of her ass and then his finger started pushing in large amounts of it into her butthole. He used one finger and then two. They slide in fairly easy and without too much pain helped by her remembering to bear down after the practice with the butt plugs. She knew he planned to ass fuck her next. Then she saw him grab a butt plug like her number 4 plug. The curved one with the looped handle. She felt it go in and winced only a little as the head pushed past her sphincter. If he had done that the previous week, she would have screamed in pain. But her week of anal training made it much easier and she actually felt appreciative he had demanded it.
"On the bed. Hands and knees. Facing me." His instructions were simple and to the point. She jumped to comply. He brought over the camera with the light and set it up at the edge of the bed pointed right at her face. On top of everything else, he had turned her into quite the porn star with a large quantity of very explicit material. But she had more important things to worry about.
