The more correct tag would be netorase. but since we don't have it on fakku i suppose that NTR works for people to understand more about what the story is.
Netorare means cuckold. A cuckold is the husband of an adulterous wife. Wether it's willing or unwilling is beside the point. This is NTR, more spesifically netorase.
...Huh. Sometimes I think we need a completely different tag for a cuckolding fetish or something, because it just doesn't feel like NTR if the guy not only likes it, but kind of encourages it.
That second panel on page 6 really threw me for a loop, didn't realise why it looked so weird until I realised the artist drawn him with a set of upper central incisors on the lower jaw and no laterals... it looks so weird, you'd think he'd google what a human mouth looks like before drawing a close up.
I was happy seeing the triple green tag of netorare, cheating and housewife but it's an arranged/set up NTR..... not bad though, the art was great enough to fill the void.
First things first, Satomi is smoking hot and I really liked her expressions while being reamed. Secondly I kinda saw that end coming a few pages in, but I still enjoyed the story. Awesome work Sendou Hachi sensei.
