There's not much "NTR" here. You either rape the girls or lose the right to rape the girl to two old farts so either way, the girls are getting raped. The "NTR" scenes are pretty a much single low effort scene recycled between all girls and both guys. Also, it's tedious and takes a long time to get.
Point is, if you're in here looking for NTR, don't, you're wasting your time. Gonna spend hours to get pretty much nothing. More than anything, this is a "mind control, rape, and dominate girls" through golf game, which is a popular genre.
