Cum

You blow your load right down here throat, thrusting your hips as you do. She sucks your rod until no more can come out.

"Oh, you fucking little cunt," you say.

"Yeah, baby, I'm a cunt. And maybe we can continue this up in my room." You take a look at her naked body, and then she walks away. You sit there, contemplating whether to follow her, or leave and not worry about getting caught by your best friend.
