Well, I did play this a long time ago, like 7 years or so. I dont remember there being one specific scene, worse than the others? But what I remember is: rape is pretty much main dish here, every encounter except maybe few of the late game ones, is hc rape. Meaning, its not: "uwu but I poop from there" rape, or "no-o baka...ah...", but a full on "my strangely drawn square shaped dick is flaccid and my asshole bloody, I wanna die". Literally, assholes get bloody in this one, as well as dicks. Everything is weirdly coloured and textured, so dicks look like rigid wooden tubes extending from the body in a downwards arch, and bodies in general remind me of medieval christian art? Like, picture Jesus hanging from the cross, only anime proportions, getting raped by a mop. Or several nazis. Or both.
And games not even all that interesting psychologically. Its yaoi logic. Things just happen.
Just pass this one. CGs are available online, so just check it out if youre interested in how this thing looks. The only reason this game is kinda well known and (in)famous, lies in the fact that this was one of the first translated bl games, if not THE first one, back in the day. If you wanna dabble in bl and stuff, try stuff like Hadaka Shitsuji, Sweet Pool, or No thank you, if you havent already.
