I just read it and didn't really get the same NTR feeling that I get from normal NTR works.
Not all NTR works make people feel the same way. Some NTR stories, you feel ok. Some, you don't. Most of the time, it has something to do with which character you can insert/empathize with. Sometimes, it's if you hate a character enough. Or if you just didn't care about the characters. Or whatever.
Heck, Hase Tsubura's Kyonyuu Yukujo Aya Netoraremashita would feel like a simple slut story, but it's still NTR.
Then there's Wamusato Haru's Yoroshiku NTR, which is very NTR, but if you insert into the younger dude, a lot of normals would call that "cheating" only if it didn't have NTR on its title.
