Based on the speach bubbles (more like talk frames), this seems to be extra mode (g)rape related.
The girl mentions that is her first time experiencing pain and shame (humiliation) like that.
And the referee calls MC "champion" when describing his slow hips swings as if savoring a virgin.
Problem with that is, at first, I thought the girl would be the champion, therefore in the (g)rape extra mode, she should've already lost her cherry. That means, either the referee bubble/frame is incorrect (possibly residue from "champion has his way in the ring") or the game will allow you to choose who, the girl or MC, will start as the champion. A two scenarios game, perhaps?
