If she says so...

"I said 'should', what do you offer so I will do?" Mr. Daniels asked.

"What do you want, mister?"

"First I want you to admit that you like it and that you won't kill me. And if you cum before I do, maybe I will pull out."

Lisa couldn't deny that she was very aroused by the act. She didn't like to be vocal about it and to say so. But she also didn't want to take a chance on that, so she submitted.

"Alright mister, you won, I like it, and I won't kill you," Lisa said reluctantly.
And now her moans and gasps were less and less unwanted since she tried to really cum quickly.

"That's an honest girl. But you haven't cum yet, do you? I will not last long, you know. But it's up to you."

Lisa bit her lips and closed her eyes to focus on the pleasure in an attempt to cum before him.
