Custom video: You've had a filthy crush on your own sister forever! You and your wife invited her and her husband on a tropical vacation. One day on the trip your wife finds photos you've taken of your sister on your phone, and worse, saved photos from her instagram, AND nudes of your sister meant for her husband that you stole from her phone! She tells your sister, and she comes in to see if it's true and berate you for being sick. Your sister cannot believe how perverted you are to lust after her like that. She yells at you and tells you how disgusting you are, and then she makes you take your phone out, look at the photos of her and jerk your cock! She teases you the whole time, isn't it weird how much your wife looks like your sister? That can't be a coincidence. She starts to feel bad for you and decides to show you the REAL thing, just once. She slowly strips down, and encourages you to keep masturbating for her. Finally, she tell you she wants you to cum. But not on her tits or ass, she wants you to do the most intimate thing a man can to a woman, and look her deep in the eyes while you cum inside her pussy. You love your sister that much, don't you?
