OKAY THIS MAY SOUND WEIRD AS FUCK BUT like please let me And help me cook? So like okay here me out Mulan plot right but adult and turn that shit into a Yaoi romance story. With the uke being in the place similar to Mulan but is found by the seme a commander/ high ranking officer of the huns after the uke is near death. The seme saves them as they see the death of someone so strategically smart as a waste and it ends sparking a relationship where the seme finds them helps them go from looking like a girl to looking like a femboy and the seme sees the uke as a boy and treats him as one while still being sexually attracted to them too. Obviously everyone is adults. Lots of male x transmasc. The main character getting taught by the seme how to masturbate, suck cock, and ride dick like a good boy he is.
