We didn’t take Joey with us because it seemed best to not put him in a position where he felt pressured to share more than he was ready for. Joey transitioned early. While it has made things easier for him physically, his age has limited the amount of exploration and social support he has had. It means that he still has trust issues. I have had some extra challenges building a relationship with him.

At the same time, as his new stepfather, I feel a responsibility to help his mother set boundaries to keep him safe in a world that is not always welcoming to young transmen. I would have been concerned about any young man his age putting sexually explicit material out on the internet, but especially so under the circumstances.

When I walked in on Joey in the den a few days ago the fact that he was taking selfies didn’t surprise me… but, my own reaction did. I was turned on by him. His sweet, slender, androgynous body was, well, hot! I couldn’t stop thinking about how smooth and silky his skin would feel under my fingertips and wondering whether my rough adult hands would make him tremble with desire when I stroked his body.

I didn’t know if he was a virgin, or not, but I knew he didn’t have much experience. His bonus hole was still tight and innocent. I would have been shocked if he had experienced being filled up by a grown man’s fat dick and being fucked the way an experienced man knows how to fuck.

Still, I didn’t think he wanted me. He was barely even speaking to me. That next morning, though, everything changed. I knew I shouldn’t do it. We had been married for less than a year and I was cheating on my wife with her barely-legal trans son. I guess I told myself that Joey and I had finally found a connection and I didn’t want to spoil it. I rationalized that we would talk about it later, and it would be a one-time thing.

It hasn’t been a one time thing, though. This morning, Ellen called to say she was coming home from her business trip. Reality came crashing back in, in a very real way. This had to stop. Just as I was getting up the determination to talk to Joey, I saw him strutting across the hallway flaunting his cute peach of an ass in a jockstrap. Twice.

I went downstairs and confronted him. He denied trying to turn me on, even at the same time that he was stroking my thigh and asking if it turned me on. Of course it did, dammit! Before I knew it, he was climbing into my arms, we were kissing, and I had a couple of fingers thrust up into his warm wet bonus hole.

I just couldn’t help myself, and Joey is a horny twenty year-old with a new favorite toy and no intention of giving it up. Before I knew it I was naked, hard, and fucking the day-lights out of my stepson. Again. He is just so cute, and innocently sexy. He doesn’t really know what he’s capable of doing to a man. His hot wet bonus hole is made to be fucked by a strong horny man who knows what sexy little slut like him is made for. A strong horny man like his own stepdad.

This has to stop! We just can’t keep doing this… after Ellen gets home three days from now.
