mud-play, suspension bondage, saliva trail (kiss), bukkake, naizuri (idk if they count as a fetish) and shota. Although they're unrelated, I somehow find it interesting. Hmm I don't know the right term to describe them lol.
Komine's route in Hadaka Shitsuji. Although it's one of my favorite games of all time, I couldn't finish his route because how much I hate most of his h-scenes.
His good/light endings didn't surprise me at all since he was mostly being ahegao and funny guy. I bought this game to try Sakuma's...
