Stepmom teaches stepson how to have sex but he keeps fucking the wrong hole

I wanted to give my stepson the best in life and one of the most important things for a man is sexual confidence.I tried teaching him about sex with books but I could tell it just wasn't helping his confidence at all. I decided to let him practice with my body in real life so he could learn sex and I could teach him, physically. He got the idea of sticking his dick inside of me right away, the only problem was he got the wrong hole. I didn't want him to lose confidence so while I calmly informed him it was the wrong hole, I let him fuck my ass hole some too.
