It's Summer break, and accidentally walked in on my step-son, clumsily playing with his dick to strippers in his video game. We quickly got over the embarrassment, and as a good step-Mom, I thought it was the perfect time for a teaching moment. From what I saw, he wasn't very good at jacking off, and I felt like he needed a little instruction to push him in the right direction. I even gave him some real tits to look at, instead of his fake, video game girls. I got him some lube, and walked him through how to properly stroke his nice cock. I got a little carried away, and started playing with his balls while he jerked off to me, and got so turned on that I decided to become a more "hands on" instructor. Mama wrapped her soft hands around his stiff cock, and jacked him off until he blew hot cum all over himself. There's nothing like your step-Mother's touch
