Parts 1 & 2 of a 4 part series. Mommy has been noticing that her boy is growing up. She always thought he was cute but now that he's getting bigger and stronger, she's becoming sexually attracted to him too. She’s at a point where she can't help herself. She wants him, but she doesn’t want to be too up front about it. So instead of trying to straight up seduce him, she wants to be sneaky about it. He's naïve and inexperienced, so she knows he won't suspect a thing. Part 1 Mommy is excited her son is done with school for the summer. She’s looking forward to a lot of days at the beach with him. She bought new bathing suits for them and everything. She decides they should try them on, so she changes into her swimsuit right in front of him. She tells him to try his on. He’s a little shy to strip down, but she won’t take no for an answer. She takes down his pants and sees that his cock is rock hard. It’s exactly what she wanted, but she tries to hide her excitement. Now that she knows he’s attracted to her too, she knows exactly what to do. Part 2 Mommy comes into her son’s room and wants to talk. She noticed his penis got hard when he was getting changed the other day. It’s ok, nothing to be embarrassed about. In fact, she can teach him a secret game to play that can help, as long as he promises not to tell anyone. To get started, she has to take his clothes off, like last time. When he’s naked, she shows him that his penis isn’t as hard as last time. She explains that a boy’s penis gets hard when he’s aroused by a girl. She shows him her cleavage and thong, and it starts getting hard again. She says she thinks it’ll probably get even harder if she reaches down and touches it, so she does. It feels really good, doesn’t it? He gets harder and harder in her hand, and she tells him that when he feels really good, just to let it go, and he cums in her hand.
