A naive and overly caring Mommy comes into her son’s room after his football game. He is visibly sore. She asks if there's anything she can do for him. He insists on a thigh massage and Mommy says ‘of course’. She begins to massage him innocently on his thighs, while telling him how she wants him to feel better. He tells her to go higher and higher, and she is more and more reluctant until she is massaging his crotch. He gets an erection and Mommy notices and is visibly and verbally shocked. He fools Mommy and plays it down explaining that it is a “muscle” that is also sore. Telling her she is overreacting and he is just so sore, Mommy feels foolish for thinking it was sexual and does what he asks, massaging his penis. There is no lotion so he insists Mommy spits on it, and after more convincing she complies. He asks Mommy to spit on it over and over and she reluctantly agrees each time. He tells her he feels well enough to stand up while she is on her knees and naive mommy is so happy he can stand. She is now excitedly and unknowingly wanking her son’s cock on her knees as he stands over him. Then he busts his nut all over Mommy’s shocked and disgusted face…
