James waited for her to calm down and continued to tease her. He decided to gently start rubbing her clit with his thumb and forefinger. Mary started feeling sparks of pleasure through her. She wanted to touch herself, wanted to touch her nipples and to touch James. As if he had read through her mind, James continued to play with her clit and reached to pinch and tweak her nipples. He then stopped and bowed down in front of Mary's pussy and started to lick and suck her clit. He could feel the juices filling his mouth and he had to admit that she did taste good. It was a taste that he would not get bored of. At least not real quick like the others.
James started to get impatient and starting moving his fingers inside of Mary's heat. He plunged one finger inside. He knew she liked it rough and he did not hesitate. She let out a whimper and slowly started grinding herself to the rhythm of his pace. James loved how she was warm and tight inside. He had not fucked her yet and could not stop thinking about how wonderful she would feel. He added another finger and then another. Three fingers was the maximum she could take with the small amount of teasing she just got. He continued thrusting in and out, occasionally pressing against her sweet spot. He did not want to give her maximum pleasure yet, not when he was not fucking her. With the constant thrusting and with his other hand playing with her clit, James could feel Mary tightening up and her hips moving on their own. She was moaning loudly and her eyes were shut. While still looking at her, he slowed down the pace and stopped playing with her clit.
"Please... Please!" Mary cried out in frustration. She could not stop thinking about the peak she had just been on and wanted to cry at how brutally she was being denied this pleasure that only James could seem to have ever provided her.
"You know what you need to say," James continued to slow the down the pace until he was almost closed to stopping.
Mary realized what he was about to do and did not bother to think about what he always forced her say. She screamed out in frustration and with tears falling down her cheeks, "Please Sir! Allow your slut to come. You own my pleasure, fuck."
Hearing this, James get back to his punishing pace and quickly brought her to the edge again. With one last thrust, he finally pushed her over the edge. Mary screamed as she felt the pleasure she had been seeking all this time. Her body slammed against the mattress. Her back arched, her eyes rolled back and her pussy pulsated around his fingers. The wave of pleasure was quick as it rolled into her and brought her to a sedate state. At this moment, as James removed his finger that were coated with her juices and brought it to his mouth to suck on them, Mary knew that deep inside she did not want anyone to save her. She wanted to stay here forever with James and could not wait for him to finally decide to fuck her with his cock. Her eyes lowered to his white shorts and she licked her lips as she imagined the hard cock that was restrained in those shorts on her lips. She could imagine him coming on her face or even inside her. Thinking of this warmth inside her prolonged the duration of her pleasure and watching him suck on his fingers brought more sparks to her pussy.
James, on the other hand, had seen Mary's eyes traveling to his crotch. This had made him smile. Of course, he wanted to fuck her. But what kept him patient was the thought of Mary getting on her knees and begging him to fuck her. He wanted her to worship him and with how she had reacted on merely their fourth session, he knew that he would not have to wait any longer.
After making sure the ropes' knots did not get loose, he looked at her one more time and got out of the basement. He turned the electro-unit on and programmed it to give her slightly higher voltage shocks, but still at random intervals. He promised her to get her some water. Of course, after filling the glass of water, he did not forget to put one whole white pill and waited for it to dissolve completely before heading back to Mary. The water would do more than quench her thirst. Those pills would help increase her sexual needs dramatically. She would become more dependant on his touches and actions with her body. Eventually he would be able to release her from the ropes, but he would put a hand cuff on a long chain on one wrist. He would also place the electro-unit on a belt with instructions to not tamper with it, or the consequences would be dire. While it would be on her belly, it was locked, and she would have orders to leave the wires alone. If she needed to poop, he would remove the metal plug in her ass, only to re-insert it after the bathroom visit.
