Tell her the truth

You can't think of a good excuse and begin to feel bad that you were essentially stalking such a fine black fuck-slut.

"I'm sorry," you say, "I just graduated from high school and I've had these fantasies about fucking you."

She looks at you, obviously a little annoyed.

"I've seen some of your movies. Like Down the Hatch where you take Lexington Steele's cock in your ass."

"He was pretty big," she says.

"And I've just dreamed about having my cock between your big tits," you say.
