He could fall victim to either the strength or charms of a knight, perhaps? Or is that too cliche?

He must get laid before midnight, if he fails.. the curse will turn him gay forever!! :3

How about a double gameover? Sino and Victor go to a bar to pick up chicks and end up in bed together instead!

-He could be like does not want to penetrate other fox but ends up in need of doing it and done it.
-He gets someone doing oral and anal giving+receiving to him,being used badly because he is too hot for them.
-He can't resist another handsome muscular dragon/eastern dragon/young muscular fox and he is very horny so he let him plow his ass.
-He got spitroasted by other muscular elder dragons and has plenty of cum on him.
-He ends up being powerbottom and bottom real good.
-He plays with tentacles.
-He gets penetrated by smaller dom.

That's all. Hope one or more of these help!

dirty dnd adventures with him being dommed by various monsters
