(Her Secret Fantasy, continued by Mxyzptlk98...)

“Well, you know I’ve always had a BBC fantasy,” Rachel says. “I feel really comfortable with you and don’t get me wrong, I am attracted to you. It’s just that when I watch interracial porn I can’t help but notice how much bigger theirs are compared to yours, and if I’m being honest, I always imagine myself being the girl getting stretched open. I follow along with the rhythm of their thrusting and imagine it’s me.”

Your girlfriend reaches over and strokes your cock a little bit.

“What do you say, honey? Do you want to watch me fuck a big black cock in front of you?”

She speeds up the stroking.

“Wouldn’t it be hot watching your tiny little girlfriend being used by a guy twice your size?”
