Japanese rape scenes are stupid and lazy. Japanese creators who use rape in their story must be sent to mental asylums. They can't even decide whether the rape must make the viewers fap or feel sorry.
Every good VN, that fans consider as kamige - god game, seems to be filled with stupid rape.
I remember sitting half an hour clicking till my fingers got sore when I was playing MuvLuv while I slowly read each and every line about tentacle rape. I get it, rape is sad, boo hoo look at her suffering, but I don't need to go through walls of text to feel that. Walls of text of penis worm rape in another VN. The worms rape her so hard she becomes a really thirsty slut because of it. Some lovecraftian loli that's just meat and blood to a sane eye gets raped by a neighbor in another VN, and this guy is one of the greatest writers in anime. Stupid shit. There's a dog that rapes a girl who later kills herself in another one. Same VN has a stuffed doll that gets gangraped by a cult. Never touched another VN ever since.

Good rape scene in anime?
Perfect Blue, and it wasn't even real rape.
