She can't resist

Becca promised herself she wouldn't beg. She closed her eyes and tried to think of something, anything else. With each increase that became harder and harder to do. She knew if she wasn't in the straightjacket she'd be frantically rubbing herself. To make matters even worse her nipples were beginning to hurt too. They didn't like being covered up after all, and all her shaking was causing the jacket to rub against them. "Please...." She said softly, "Please Kennedy."

"Nuh uh, unless you're begging for a taste of me, don't even try." Kennedy said, sounding bored.

Becca shook her head, "Please. My nipples...you have to take off this jacket."

Kennedy laughed, "Oh shit. I'd almost forgotten. Yes, they must be on fire by now. Don't worry. I've got you." Becca opened her eyes and watched Kennedy approach. She thought she was going to free her, but instead she knelt down in front of her. Kennedy reached out towards Becca's chest and grabbed hold of the jacket. She hadn't noticed it before, but now she saw that the section over her breast was actually detatchable. In a swift motion Kennedy pulled it away, first from the left, then the right breast. Then Kennedy grabbed her tits and pulled them out, ensuring they were fully on display, "There, better now?" Kennedy sneered.

Of course it did feel better. She'd already been naked in front of Kennedy, so what did it matter that her tits were out. "Yes." She told her.

Kennedy reached out and grabbed a nipple and twisted it harshly, causing Becca to scream, "Yes? That's all?"

Becca was frantic, **** to stop the pain, "Yes Mistress." She said hurriedly. Immediately Kennedy let go.

"Mistress? Yes, I like that," Then she grabbed Becca's other nipple and twisted, "but what about a thank you?"

"Thank you Mistress!" Becca shouted.

Kennedy just scoffed and got back on the bed. That ordeal had actually provided a distraction from the vibration, but now she could ignore it no more. Her world narrowed to just the sensations coming from her piercing. She could have cum a million times, her need was so great it was all she could think about. Time lost meaning as she struggled but finally she could handle it no more, "Please! Kennedy! Mistress! May I lick your pussy!"

Becca felt Kennedy's hands on her breasts again and opened her eyes. Kennedy smile wasn't pleasant, "Oh, poor baby. Is it too much for you? Too bad you waited too long, it's already at full power. See you in an hour!" Kennedy twisted her nipples again and then everything went dark as she pulled a blindfold over Becca's eyes.

Whether or not it was really an hour was lost on Becca. It was pure **** no matter how long it lasted. When it finally shut off and the blindfold was removed she didn't hesitate, she dove forward and started licking. Even when Kennedy came she didn't stop. She couldn't stop. She ate her out over and over until finally Kennedy shoved her away, "Good job pet. Here's your reward." Kennedy pressed a button on her phone and the orgasm hit Becca. It was like her whole world exploded into pleasure. It was amazing, and as the wave crashed over her she passed out and fell asleep.
