My stepfather is so kind and always drives me to driving school and I just wanted to say "thank you" when I picked him up ;). When he arrives, I sit down next to him and start playing with his trousers while I chat about driving school. At first he tries to push my hand away, but I can clearly feel the bulge and grab it. While he's driving, I lean over to him and start sucking his now incredibly hard and big cock. I briefly consider letting him have a proper go at home, but the risk of being caught by mine is too great. So I let him turn onto a forest path where he can finally give it to me!
