Not something Sabrina can win.

"I'm going use this on you," Becca said, brandishing the powerful vibrator, "and I'm going to time how long you can last without having any orgasms." She switched the thing on to a low setting and was surprised at how strong the vibrations felt even through the handle. This thing was the real deal. She smiled devilishly. It was going to be so fun watching her busty friend writhe. "Now, I have a duration in mind, and we're going to play for at least that long. If you come early, I'll deduct time from your progress and we keep going. If you come again, I'll deduct more time, so you'll have to go longer. Understand? The game ends when you reach the goal time."

She lowered the buzzing head to brush against Sabrina's nipple and the girl jumped with a gasp. "Oh wow!" Then, after a pause, "Oh, no."

"Oh, yes." Becca didn't really have any idea of the units for her game, but that didn't matter. Sabrina was her plaything in the moment; she could do whatever she wanted. She'd figure it out as she went. "Let's begin!"

Sabrina wiggled a little in her bonds, as if trying to escape, but Becca had no problem forcing her onto her back to **** the rubberized head of the device between her bound thighs towards her sex. Sabrina gasped and twitched as Becca found her clit, and then let out a long, low moan of great pleasure. "Ohh fuck, that's good."

"Okay, starting the timer." Becca pulled out her phone and started a stopwatch instead of a timer. It didn't matter how long it took; Becca was going to sit and wait for Sabrina to succumb before the game really began, and she wanted to know how long it would take. She was sure she'd have a lot of opportunities to use information like that. Now all she had to do was sit back and enjoy the show. Of course, she also snapped several pictures and took some video for herself. It was too good to pass up.
