There is supposed to be a full moon tonight. And you're about to become a man. Mom breaks this down for you - the curse of the women in your family. When the full moon arrives, she will start... changing. She can't explain fully, but says she will become very hot... very aroused. And you must promise to keep her locked up in her room. The lock will be switched to the outside so you have full control. PROMISE TO KEEP HER LOCKED IN. You don't know how far she'll go... After locking her up, the sun goes down and you start to hear her... it sounds like she's going through something for sure. You hear her moaning and groaning, begging for you to let her out. "Don't you want to FUCK MOMMY?" she moans through the door. You step back and feel your pants tighten up. "Come on now, let me out. I'M SO HORNY. FUCK ME." You can't help your physical response... but must hold back from letting her out. Only, soon her tone changes and she's saying that she's fine now. She tells you that it's all okay and she just needs you to let her out... she's begging now, but for help! Her moans and groans are terrible and you can't do anything but open that door! She's on the bed. Smiling. She looks different. Her hair is darker, she has on bright red lipstick, and she's dressed really sexy. This is different from your Mother. This is something else... but... still her, you can sense it. She says to come to her, that she needs to relieve herself. And that you can help her with that. Once she fucks you, she'll be back to normal. And don't you want to help Mommy? Climbing onto your cock, she rides you like crazy! She's moaning wild and grinding her pussy on your cock, saying she must cum and you must cum... that her body NEEDS you to cum, and she NEEDS to do this... NEEDS TO... CUM... OH... YES! YES! YES! She's riding harder and faster, taking off her corset to allow her breasts to fully bounce and make it even more of a struggle to hold back. Don't hold back! YES! YES! YES!
