Dani whimpered. Michael had left her hanging in a harness which didn't let her move at all, with a vibrator running on low in her pussy, held in by a leather pad and straps. She was doing her best to cum, but it was set too low, she just couldn't manage it. That didn't stop her from trying. She knew she was close, and she knew he told her that if she came four more times, she would get to go home. She wasn't sure why, but she trusted him. But every time she thought she was starting to get close, it turned out she wasn't, causing her to cry in frustration. It was always wishful thinking.
When Michael came back into the room about an hour later, he saw Dani alternating between moaning and crying. He smirked.
"So, did you cum?"
"Fuck you! Turn it up so I can cum!"
"Tsk, you'll have to be more polite if you want me to do that."
Dani stared, then lowered her head. "Please turn it up so I can cum."
Michael walked over and roughly squeezed a breast. Normally, this would have made her wince, and she knew it, but instead Dani gasped and moaned, finally feeling like she might be close.
"I'm altering the rules slightly."
Dani stuttered, "W-what?"
"Oh, you still get to leave after four more orgasms. But I have to be present for all of them -- they don't count otherwise. I realize I'll have to unhook you from this harness at some point, and we can't have you rubbing that hungry cunt to a few quick cums, can we?"
Dani grit her teeth and her face turned red, and it looked like she was about to yell at him, when he turned up the vibrator to medium, causing her to inhale sharply. She could feel herself get closer, her hips were rocking. Mike said, "Do you have a problem with that?"
