The secret life of the demon king
The uke started out as a top (as in was hesitant to even touch another mans dick & was more focused on his own) willing to bottom for money to a verse (began enjoying it but also wanted his dick focused on) relatively quickly. And then like at chapter 20 a bottom with absolutely no desire to top: he straight up didn't give a shit about his dick at this point & only wanted a phallic thing in his ass, literally all the people touching his dick were of their own directive he never once asked for it & every single fantasy he had was of Arthur fucking his ass & neglecting his dick. Pleasant. He's also a tall, thick, handsome man. Mmm delicious. And his clothing accentuates that. The Top remained a top all the way through, even when forced into a dress. He was quite feminine to. I also like how they realized how cringe the knights were & cut them out when they were no longer relevant instead of having them stick around for pointless drama.
