Starting off easy

He rubbed the coin with a smirk, "first, I wish that you could not stop from becoming aroused in my presence once a day until you cum." He leaned back in his chair as he watched her mind whirl. She was trying to reconcile these two realities: one where he had the coin and she needed to get it back, and the other where she was growing incredibly aroused.

"Sarah?" Mr. Boston asked, raising an eyebrow.

"P-please, make it stop...." She moaned, squirming in place. "J-just g-give it back."

"Oh no, my dear. After all, I needed it to complete my set," he said, motioning to the box inlaid with all of the other coins.

She was surprised to see more coins, but her focus was far from on them at the moment.

"Do you know what the benefit of having all of the coins is? I can make as many wishes as I want," he grinned as he moved closer to her. "I wish the only way you could come from now on was by making me cum," he said, running his fingers across the coin yet again.

Sarah fell to her knees as the arousal between her legs grew and grew and she knew she would get no relief unless... No! She could hold out. I can do it... I know I cock- can! I know I can! "You don't look too well, Mrs. Saunders. Perhaps I have the solution for you?" With her head hung, she heard his zipper open up in front of her and the sudden musk of a cock hit her nose. "It would be so easy. Just make me cum and you can get relief. Otherwise, the pressure will only keep building. I suppose you could leave, but how would you take care of your arousal? All roads lead you back to me."

She knew he was right. The only way she could get any sort of relief was to pleasure him. At least it would just be a handjob, or a blowjob at worst, right? Maybe a blowjob would be quicker? Her mind was far away from her husband and only focused on her unbelievable arousal. "Fine! Fine!" She grabbed his cock, taking in the sight. It was... so much bigger than her husband's. With a small sigh of hesitation, she took it between her lips. That was all he needed before grabbing her head and slamming his hips into her face.

"That's right! Good girl! Take my cock!" He shouted, his cock slipping back and forth between her lips. "Look up at me while I fuck your married throat!" Sarah knew she didn't have a choice, so she looked up at him. Her makeup was running down her face as she was **** to take his cock. Well, **** was a bit of a misnomer; she had chosen this... kind of. "That feels amazing! I wish you had to suck my cock every day!" He yelled absentmindedly, the coin still in the palm of his hand. Her stomach dropped even more as she heard his wish; she knew she would have to do it. She had **** now. He caught her off guard as he slammed his cock deep into her throat one last time, cumming inside of her mouth. Instead of protesting, she found her body wracked with an incredible orgasm. She shook and spasmed before falling limp.

Mr. Boston pulled away from her and leaned back against his desk, "I'll need to work on my endurance, Mrs. Sarah. But, for now, I think you owe me a word of thanks for the orgasm."

"You've got to be..." She started, trying to steady herself.

"I think that I am being rather kind, all things considered. I could turn you into a dumb bimbo who is obsessed with my cock. Or maybe I could make it so you were my wife instead," he mused, tossing the coin and catching it.

"No, no, please! Thank you, sir, for the amazing orgasm! It was so good!" She said hastily.

"Good enough. Now, I think we'll stop for today. We need to take this slow, after all," he winked. That was a complete lie, but he wanted to taunt her. He could go as fast as he wanted and she would have **** but to go along with it. "One last wish: I wish you couldn't tell your husband about what happened today or me having the coin." Mr. Boston was playing fast and loose with the rules, but he would get a handle on them. He had let his excitement get the better of him today. That wouldn't be the case tomorrow.
