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.
