When I was young, I hated her. Now every time I visit, I want to fuck her so bad. She knows it and plays up to me. She flirts outrageously with me and has in recent times flashed me her breasts, pussy and ass. When I lived at home, not long before I had to move out, she caught me masturbating and stood there watching for what she said was around five minutes. Way before I noticed she was there. She's such a good looking woman, now at thirty eight years old. And that's why I resented her when my dad met, moved her in and then married her. I didn't want my mom replaced, but as I grew older, I obviously knew she hadn't. My dad's much older than her and as far as I can tell, they hardly ever if ever make love any more. I know this to be the case, because I asked my dad in a round about way when we were fishing together. Saying to him "She must wear you out in the bedroom". He answered by telling me "She used to. Now I prefer fishing".
My dad goes away shortly for his annual sea fishing trip. His wife has asked me if I'll keep her company and maybe stay over. I know in my heart what she wants. I also know in my heart it would be wrong to cheat on my dad. But I don't think I'll be able to refuse her, or my sexual urges to fuck her for all I'm worth.
