Genderless androgenous alien vs my human male

[TheGameMaster]

I have been craving to play opposite a character who is completely gender neutral. In fact your character shouldn't have genetalia at all. It could be that you develope genetalia to match your partners after you find one or you could stay smooth down there for the entire play. Either way I'm mostly interested in your mouth.

This can be con, non-con, or something in between.
