It's Simple

There are some trans women who's cocks I'd suck, and some I wouldn't. Simple as that.

If she's super fem, really put the time and effort into her appearance, grooming, makeup, hair, hormones, and just happens to have a dick, so be it. I'll validate the hell out of that thing, give her a good time.

I don't think she'd want it, but if she wants my ass, I think I'd just have to let her have a go (condom preferred). I'll take hers if she asks (again, condom please).

I'm not letting all that effort go to waste, even if it ends with her strange cock in my mouth. So come on over, darling, I'll take good care of you. We'll play house.
