But you start thinking about her, and those curves and those legs and her hot, thick body and your cock wakes up. The next thing you know, the water in the shower is turning cold because you've used up all the hot water as you masturbate to thoughts of fucking her!
"No, not really," you admit.
She sits back, the tilt in her head conveying her disapproval. "Really. How unfortunate. Here I was hoping that you had a *good* reason!" she titters.
"I can do better," you assure her quickly.
