I've secretly been wanting your cock for so long now. I know we are brother and sister but I dont care! I want it! I know you will be too scared so I have no choice but to blackmail you into fucking me. I have to be sneaky about it though, so I tell you that you have to watch your best friend fuck me or I will tell everyone that you still pee the bed! Which means good luck finding a girlfriend! You reluctantly agree to watch. I push throughout to get you to do want I want. Starting with having you pull your cock out and touch yourself to full blown fucking me! It works! My warm sister pussy makes you blow a fat load all over me!..Along with your best friend!
