OP Here, it may sound like BS, but to me the fetish comes from how much i like women.
I like them so much, and i think they're so pretty, that i want to be in their place, so to speak. One of my biggest fantasies is having a girl i like dress me up in her cute and/or sexy clothes, and taking the lead from there. It doesn't hurt that i find anal to feel very nice, either
Also, i don't know if this thread should be 2D only, cause i do have a lot of quality 3D stuff. Let me know what you think
