Cum on Mommy's Ass Crack - you come to the living room, your Mommy is on the sofa reading a magazine. You ask her what is she reading, she tells you she found a very interesting article about exercises to work her ass muscles, she feels like she gained a little bit of weight recently and she could use some tone up. You're contradicting her, telling her her ass is just perfect. She's a bit confused, she didn't even know that you're paying attention to her ass... that's a surprise! You're finally finding the courage to tell her that you've always been attracted by her ass, and ask her if you can look at it. She refuses at first, you are after all, her Son! She finally agrees and lets you take a look. Her ass is just perfect. She teases you with her robe, she touches her ass. All of the sudden, she turns to you and sees you got a hard on. She decides to make this day extraordinary, and asks you to wait for her to get back in a little while.
