Я учу 18-летнюю, как подрочить

I ask an 18 year old how his day at school was, and he says, "fine," but I can tell from his face that something is on his mind. He divulges that his friends have been talking about jerking off, and wonders if I can show him how. At first I tell him that I think it's inappropriate, but he convinces me that he is of age and that I have always said we learn best by doing, not by explaining. I proceed to show him what makes me feel good, and ask him to explore his body, taking off his clothes as I grope my cock, balls, pinch my nips and finger my hole. We start stroking together, and I ask if he's getting close. Then I tell him we're going to cum on each other, as I shoot my load.
