Fucking my Dad feels like getting payback

I know how this posts sounds but I don't really think of what he's doing as abusive or at least not anymore. Even back when it felt much creepier it felt like I was getting worshipped in this kinda fucked up way, and I didn't put up much of a fight.

I'm in my early 20s and my dad is divorce and already in his early 50s. Before he was divorced it was obvious that he was embarrassed about me not being a jock like he was at my age, and even made a few comments about friends of mine, made it even more obvious that he thought I should be more athletic like him. I read between the lines and realized he thought they were more manly than me.

When I went to college, he got divorced and I didn't see much of him until I was trying to move back home to save money after a falling out with a roommate. Since going to college I began lifting and he hadn't really seen much of me since I made visible progress. When he agreed for me to move back in and saw how my body had changed, his attitude toward me changed over night.

At first the was a lot more friendly around me, which turned into comments about my progress at the gym, my body, and hints about my sex life. I realized quick that he was at least bisexual due to some comments he made about other men, he realized I knew and the filter came off even more.

When I started coming home from the gym I started noticing him basically waiting for me, asking me about my lift or copping a feel of my shoulders or biceps, which turned into pushing me to pose for him, taking my shirt off to do it, or letting him feel my arms while I did it.

The more he pushed for this, it was obvious it was sexual and I pretended like I didn't know. When he was greeting me at the door he was wearing less clothes until he was in his underwear and instructing me to do the same thing. What made it impossible to ignore was flexing both my arms for him, watching him open his mouth, stick out his tongue and lick my biceps down to my pits. When I lowered my arms he whined for me to keep flexing, I lifted them, and he kept licking me.

I didn't know how to react to him coming onto me that aggressively but I continued to play dumb a little as he kept pushing for more. Honestly watching his attitude change in front of me was the best part, feeling like now that I actually have a body that I'm somehow "manly enough" for him and, in some kinda fucked up way, he's treating me like the man of the house.

It's past the muscle worship, way past that, when I stopped playing dumb and realizing the control I could have over him I started taking advantage of it and it's gone past sex. I've already fucked my dad more times than I can count.

Not sure who's into this kinda fucked up dynamic with him, but if you are, hmu over DMs.
