My son is freshly 18, and is still a virgin! I know he masturbates, and get the sneaking suspicion he spies on me. One day I barge into his room claiming dinner is ready, knowing that I am going to walk in on him touching himself. As I come in the room he is extremely offended, and embarrassed. After a lot of coaxing I convince him to let me show him exactly what to do. First with my hand, then my mouth, and then of course my pussy. I mean, this is what a good mommy does right?
