As my stepson matures, I want to make sure I’m there to teach him everything he needs to know about being a man. Today, I stumble in on him shaving his balls, so I lend him a hand to make sure he does a good job. Later, he asks me for some condoms before heading out to hang out with a friend. But if he’s going to be fucking around, he needs to empty his balls first so he can last a while. I fuck his tight asshole and he jerks himself until his balls are completely drained of all his warm cum.
