Incest

"So Stace," You say. "Do you like incest?"

You look intently at her eyes, gauging her reaction. She furrows her brow. "Uh, not really. I mean, I don't have siblings right? And the thought of fucking my Dad sounds quite frankly disgusting."

You chuckle as the image of the fat football coach fucking your own girlfriend rushes to the forefront of your thoughts.

"Well, I can change that," you said. You hold up the marker.

She bites her upper lip. She's considering it. Experimenting with it. Would things go too far? She doesn't know. But again, the marker could do anything, right?

"Go ahead." She lifts up her top.

You scribble "INCESTUAL FREAK" and "THINKS I'M HER BROTHER" around her breasts.

Nothing seems to have changed. Until Stacey speaks.

"So what did you write on me, big bro?"
