For two weeks, Bill had come into her office daily and demanded she suck him off, only allowing her to cum if she had his cum on her face or had swallowed it. It had come to be that she could only cum if she could taste his; he was doing a great job of training her to crave his cum. The third week, he had her swallow him or wear it in her hair without getting her off. By the 4th week, she was asking him to come to her so she could get a mouth full of his sperm, she didn't feel right without the taste of him on her tongue. At the end of the month, she was so horny from not being allowed to cum for two weeks that she swore if she rode a bike she'd have an accidental orgasm.
However, Bill had forbidden her to cum, and she wanted to please him so she didn't. There was something about being denied yet open for his use that she found intoxicating; she liked feeling like she was just a toy to be played with at his whim. And too, because she wasn't allowed to orgasm she was constantly ready, hot and wet for whenever he wanted to take her. She knew when he finally did it would be too much for her to handle and was kind of ok with not getting to orgasm, as frustrating as it was. She liked that all she could think about was his cock and how best to get his cum, liked being horny and wet and ready at all times. Her nipples had become extremely sensitive and were hard all the time; her lips were always swollen and shiny from the lip gloss she constantly applied to advertise her mouth was ready for him.
One day Bill came into her office and she was busy wrapping up a client call. It took a minute or two to get the call finished, and when it was done she hurriedly hung up and dropped to her knees. Bill came over and grabbed her hair, pushing her over the desk.
"You weren't ready. Lift your skirt."
Nina started "But I..." Bill slapped her ass hard. "Shut up. I don't care. Lift your skirt."
Nina bit her lip at the sudden pain and quickly lifted her skirt to her waist, exposing the garters and stockings he liked to see.
Bill eyed the red mark his hand had left on her cheek and adjusted his crotch.
"You weren't ready for me, and for that I'm going to spank you. 10 times. I want you to thank me after each one."
Nina sputtered "But.."
"OW!" Bill had smacked her ass again hard, this time on the other side and on bare skin.
"I told you to shut up. Unless you are thanking me, I don't want to hear a word. If I don't hear you thank me, I'm going to start over at 1."
Bill grabbed her hands and held them tight at the base of her back. This left Nina bent over, exposed and unable to move. He kicked her legs apart and softly touched her pussy, which was wet and swollen from the last few weeks of denial. The gentle touch set her afire, and when he stopped she felt abandoned.
Whack! Nina jumped, unbelieving that he was actually doing this. But she knew he would be true to his word and quickly said "Thank you!"
Whack! "Thank you what?"
"Thank you for disciplining me"
Whack! "Why do you need discipline?"
"Thank you! Because I wasn't ready for your cock when you came in."
Whack!! Nina's right ass cheek was on fire.
"Thank you!"
Whack! "What are you?"
"Thank you! I'm yours" Nina's eyes watered with the sting of his hand.
Whack! He moved to her left cheek. "Five left. My what?"
