Stepfather teaches me about anatomy with his muscular body

My stepfather is a man who knows how to teach a lesson, and when it comes to the subject of anatomy, he's the go-to guy. He's a bodybuilder with a massive cock, and he's always ready to show off his skills. One day, I found myself alone with him, and he decided to take advantage of the opportunity to teach me about the female anatomy in a more hands-on way. He started by stroking his huge cock, and then he moved on to my pussy, making me moan with pleasure. I was so turned on by his muscular body and big cock that I couldn't help but cum all over his hard shaft. It was a lesson I won't forget anytime soon, and I can't wait to see what other lessons he has in store for me.
