Your mom's friend shows up at the house and invites herself in, just when you are having a wanking session to photos of her mouth. Your ultimate fantasy is to be swallowed by her huge, beautiful maw.  When she walks into the livingroom, she sees your laptop with her mouth wide open on it and starts asking questions. You tell her your a shrinker and you fantasize about her mouth. She is flattered and promises to never tell your mom. She sees you hard and she is aroused herself. Out of curiosity she wants to wank your dick and watch you shrinkn down. She can't believe her eyes. Now that you are the size of an apple seed she wonders what you would like to do next. You tell her you want to go into her mouth. She agrees, warning you to stay away from her teeth.  Just as she pops you in her mouth, your mom calls. With you in her mouth she talks to your mom, and the next thing you know, you have thrown yourself down her throat. There's no way to bring you back up now. I feel your wank flutters in my gut and  again, I'm aroused! I panic and head out of the house. No one must know!!!
