I think the bri is trying to hypnotized him that what they're doing is normal bro stuff and make him remember it or something, but deep down Mc kinda have this feels that its wrong and f**d up, but since his body is kinda used to the s*x of course he'd like it, that it maybe the hypnosis didn't work and that he remembered all they did and that he's being hypnotized and made to do shit, so now he's trying to pretend and go along with it...? ┑(￣Д ￣)┍
I hope they explain that further next chapter(〜￣△￣)〜
Oh I understand your take on it. I want them to tell us what's going on tho
So basically what's happening is he's probably pretending in the first chapter of season 2. Either that or when he's hypnotized he remembers now
