Every time I come around, you are always staring at me and your sister. I'm getting really annoyed with it because I just want to be able to enjoy my girlfriend in peace. But you're always fantasizing about us and wanting to watch. I'm disgusted by you. I ask you to make a deal with me: I'll show you how I like to be touched by your sister, and you leave me alone from now on at family functions. You're not allowed to play with yourself while you watch, and you can never tell ANYONE this ever happened. I remind you that you could never please me like she can. I use a little verbal humiliation to show you who is boss, and question if you can make a woman cum. I put on a little show for you, tell you how I like your sister to touch me, and lick me. I start to play with myself until you watch me make myself cum.
