Mother masturbated, and the son crawled out and received a sexual lesson

Mother read an erotic book and masturbated on the protagonist of a handsome man in the living room of the house. The woman thought that she was at home and a sexual scene in the book so relaxed that the hand herself crawled to the clitoris. I thought that to masturbate quietly to the arrival of my son from a training session, that I did not hear how he came. The guy burned his mother for masturbation and crawled quietly to touch her pussy. He himself did not notice how his mother accepted his hand and continued to caress the clitoris. So the son received a sexual lesson from his mother and gave her a tail.
