I (your step mom) notice that you’re having a hard time with your anatomy homework. Your currently studying the penis. Being the caring step-mom that I am I offer to help you with you, I do know a lot about the anatomy of the penis (and how it can give you pleasure). Since practical learning is proven to help people retain information I ask you to take your cock out and start showing you the key parts of it. You’re a fast learner, and watching you listen to my every word makes me so hot, I know it’s wrong, but it feels so right! You do so well in our lesson that I reward you with a JOI. I give you detailed instructions on how to stroke your cock, and I lead you to a mind blowing orgasm! I’m so happy we had the chance for some quality step-mom and son time, now clean up dinner will be ready soon.
