You haven't seen your cousin in years, but for this Thanksgiving your family decides to get together again. You get to their house and to your surprise your cousin is all grown up and hot! Well maybe not as grown up as you think...While she's showing you the guest room she bends over and you catch a glimpse of something beneath her skirt. Is that a diaper?? She leaves with her mom to go to the store and you can't help your curiosity. You sneak into her room and find a stash of diapers in her closet. So she really was wearing one! When she gets back home you and your family are all in the living room catching up. Your cousin is sitting on the couch and you can see her diaper peeking out from beneath her skirt. She catches you staring, but then turns more towards you and gives you a better look beneath her skirt. Why did she do that? Soon you can actually see her start to pee herself in the goodnites. Right in front of your family, but no one else knows but the two of you. Later she goes to her room and you follow her in. You confront her about her naughty behavior, but she quickly turns it on you saying you were the one staring at her trying to catch a glimpse of it! You bicker with each other until she suddenly changes her demeanor. She admits that the thought of you looking while she pissed herself with all your family around turned her on...She runs her hand up the diaper and you can't help but feel turned on too. You quickly start getting hard and she takes notice. Are you getting hard?? Geez I was just joking! I'm your cousin...It's too late for you though. You're horny and you want to watch her pee fill up those goodnites again. You convince her to piss herself again in front of you. She stands up and you watch as she goes and leaks all over! You soon start rubbing it despite her warnings that you two shouldn't be doing this. But she can't resist either. She's still leaking so you go into the bathroom and fuck her good over the toilet with her diaper pulled to the side. Then you cum into her diaper!! Soon after you finish her mom calls you for dinner. She starts to take the goodnites off, but you tell her not to. You really want to make me wear this soaked, cummy diaper to dinner?? I guess it can be our little secret...
