I'm rating it like this, because it didn't satisfy my tastebuds.
If you're into the boyfriend/husband enjoying the wife cheating, and being fully into it, then give it a try, because my rating is based on how it hits my NTR fetish.
If you're into the wife cheating on the husband, without his permission, then this is not the game for you.
The choices are based on what the husband allows. The husband HAS to give the wife permission. Not judging others if they're into that, but quite frankly, I prefer it to be much more naughtier.
The wife doesn't have real choices in this game, only the illusion. It's really all down to the choice of the husband, and the choices are who to screw.
Everything else works fine, and I like what they did with the animations. Just let down. Lots of choices, but only real fetish - voluntary cuckoldry. Takes away the spice for me, but maybe not for you.
**Edit: Apparently, there is a route to straight up cuck the husband without his permission, but it's tricky to pull off. For a Netorare game, I kind of expect that route to be more obvious, instead of pushing me towards getting the husbands permission**
