Cuckold my brother's wife

It started well, but ended meh. I don't know what happened. It had everything to be Poison's best netorare: a situation where the netorare was deserved, the protagonist was a real go-getter, no prudishness, and the sister-in-law's attitude was perfect for defil. But nothing. Around the halfway point, it turns into a netori. Basically, the protagonist and his sister-in-law just start having sex without any further explanation. In fact, the blackmail subplot almost seems thrown in for no real reason, just to make it seem like netorare, when it's really just a guy and a woman having great sex. There's no real love for the husband. What really bothered me was that they reused scenes. But those bastards included three scenes in the bonus features that they could have easily used instead of the reused stuff. In fact, I couldn't care less that they put it in the extras because the girl doesn't put up any resistance anymore. They should have included those extra scenes at least before the Netori started, but oh well. At the very least, I'll say that the positive thing is that the sister-in-law maintains her attitude until the end, and that's appreciated because usually the girls end up as generic whores without a trace of what attracted us to them in the first place. Anyway, I'll give it a three because the first part of the game is what they promise, Netorare, and because the girl maintains her exquisite attitude in the long run, but beyond that, it's not a game I'm going to play again.
