You mean
yanzuma? It's a decent NTR game depending on what you're after. Was popular in this thread when it came out due to it being one of the earlier games to really focus on NTR as a fetish, particularly in the protag's case.
But it isn't that long and some people dislike it for a few reasons. I know one poster who was put off due to it featuring a male on male scene with a side trap type character, though the main focus is on the wife. I can't say any more than that without major spoilers, but it is there for a good reason.
Personally I enjoyed the NTR part, was a little disappointed in the pacing and forced development. The heroine isn't exactly tough to get the pants off, and I'm not so big on heroine's who are too easy. I much prefer a proper seduction from Mr. NTR over force/coersion or a slutty heroine who will easily cheat the moment the protag isn't watching and a hot guy makes a pass.
But like I said, it's not that long. You might as well try it and see and if you hate yaoi there is only a short scene or two which you can skim through while concentrating on your text hooker and not looking at the game window. I believe there is enough enjoyment to be had to make it worth the effort, even if it isn't perfect.
