She makes it interesting. (Sexfight)

She lies down on top of you, her breasts pressing against your body as she smiles playfully, looking at you straight in the eyes. For one moment, you felt like you were being sized-up as if you were prey before the eyes of a very hungry predator.

"Shall we make a bet?" Her smile widened, eyes sparkling with manic confidence. She rubbed her crotch against your hard-on, and you fail to suppress a moan. She giggles in your ear, making your cock twitch even more.

"I bet... I can make you cum in say.... 7 minutes. Maybe less. If you can survive that, I'll let you have me for the night. If you can overpower me and make me cum before the time runs out... I'll introduce you to some of my friends."

She slips her tongue into your mouth and makes out with you slowly and sensually, before pulling away. Your mind is already gone, slack with lust. You must have her. Before you could reply, however, she places a finger on your lips, quieting you.

"If you lose, however... you're mine for the rest of the night, to do with as I please..."

You stare at her dumbly, and nod - sealing your fate.
