Sophia says "Fuck the rules"

"Fuck the rules," moans Sophia, "Fuck me right now."

"You can't," Emma blurts out, looking scared. "Your cock is for me."

"Baby, you're a slut, right?"

"Yes, John"

"So what do I do to you?"

"You fuck me."

"Is Sophia, your best friend who is naked and on top of me a slut?"

"Yes, Sophia is a big slut," Emma replies bitterly.

"So what do I have to do to Sophia?" you ask your girlfriend?

"You have to fuck her..." Emma concedes and without skipping a beat you slide your dick inside of Emma best friend's cunt. You got in all of the way with one motion. There was probably about a bottles-worth of natural lube already on my cock, after all. You feel a surge of excitement as you realize that Sophia's is the first new pussy you have felt since meeting Emma.
