It’s a bit more complex with a trans boy as it’s the feminine mind that is such a huge turn on to me, it doesn’t really matter what’s in your pants. That doesn’t mean I still don’t love the thought of them being denied, an aching, well edged pussy is a beautiful thing, but the combination in a trans girl of the femme mind and a cock to cage up is just such fun.
I also have a weird desire to make trans boys dress up in very girly outfits, I have no idea why, it’s really fucked up, but there’s something about putting a trans guy in a very pretty dress and denying them orgasms that delights me. Go figure.
