ガールフレンドの義理の息子を誘惑

I stopped by my girlfriend's house to chat but I only found her stepson at home. I decided to hang out for a little while and wait for her. I sat on the couch with her stepson and talked to him about college. I caught him looking at my legs and started to get a little worked up. I started wondering if he had any experience with women and found out he had none.
