Masterbate

"I dare you to play with yourself for five minutes," Trevor said.

"W-what?" Naomi stammered. "Can I at least stay here?"

"Sure. This can be a more private show. Although I can't guarantee that the people around us won't want to watch."

Naomi grabbed her breasts and began massaging them in small circles. Sure enough, as soon as a soft moan escaped her lips, the people around her stood up and tried to get a better view. Naomi found that this turned her on even more, and soon she found one hand sliding down to stimulate her pussy.

"Ummggh..." Naomi closed her eyes and bit her lip to try and stifle the moans as she thrust her fingers inside. She was almost there...

"Okay, time's up," Trevor said, reaching down and grabbing her hand.

"What? No!" Naomi exclaimed. She opened her eyes and found herself staring at Trevor's large, rock hard cock.

Trevor noticed her stare and smiled. He brought her hand up to his lips and licked her fingers, covered with the scent of her juices. "Your turn," He whispered.

"I dare you to stick that cock in me. Finish me off... make me cum again... please..." Naomi moaned.

This time he didn't bother correcting her about the rules of the game.
