Gibo

I know it's not much use flaming hentai but, seriously, this deserves to be the lowest rated hentai on MAL.

I came across this when looking for a nice incest to watch, and thought it was a decent one. But I was in for a horrible surprise. It was worse than that fan-made narutoxsakura I watched some time ago.

When I watch hentai, I want my sex scenes to be well animated with as little recycled scenes as possible. But Stepmother's Sin managed to complete each sex scene with less than 8 frames. It's just a picture with the genital parts moving---like there's a magnifying glass over ... it or something. Some scenes look as if the makers just found some cardboard, drew characters on them, and just rubbed them against each other. I've seen manga that's better animated than this. And it tries to hide it's crappiness with it's dark atmosphere.

The voice actors were just as bad, if not worse. The step-mother character's VA was just so bad at making sex noises, and the only lines she says seems to be "No. Definitely no." which sounds very awkward and forced. The main guy character was a little better but he made me laugh so hard when he said "sex" "sex", and I was literally rofling when he said "I'm cumming!". This was the funniest thing i've heard in a long time. I don't remember this having any bgm except that lightning strike when the guy ejaculates.

This was a bad hentai. But I won't discourage people from watching this because they might realize just how well other hentai/anime are animated after watching this.

mostly i like how hot the stepmom is, she is very nice. the story is nice but the animation is not that great, i wouldve like to see different scenes and not the same thing over and over again, perhaps there should be a redo version of stepmother sin, i would watch it,

Gibo focuses on a young man who saw his mother having an affair as a child that made him detest women. He then goes about raping his mother and sister because he beliefs all women are sluts and shouldn't be treated like people. For a rape hentai it has a passable story, but it really isn't anything great or interesting enough to make you want to invest in to it.

The real ... killer of this hentai though was the art and animation. By itself the art was okay maybe something around a 5 or 6 out of 10, but the animation is horrible. Majority of the sex scenes are just a few frames going back and forth or even worse a still image that is just being warped to appear that there is some kind of movement. When studios make clunky animation or few frames its easy to blame budget, but when its literally just a still image being warped its just insulting to viewers. There is also awful cuts and transitions that look like something you could make in windows movie maker.

Overall this one is a hard pass on recommending to anyone. The rape and cheating make it already a niche hentai, but tossing on top some of the worst animation I've seen puts this in the garbage tier of hentai.
