The hottest part of this series is Hinako's smile. NTR almost always falls into the trope of the woman "losing to pleasure" or "losing to a superior dick". Hinako is totally in control of all the games she plays, and however far the cheating goes, it'll be entirely her choice. She's getting touched by other men because she wants to be, not because she can't help it;. If she ever does 'cross the line', it'll be because she thought it's the more exciting option.
I also really like that since we only see things from MC's point of view, we can never really know what Hinako's thinking. Not only in terms of how far she'lll go, but how she feels about it. It's obvious she's delighting in being lusted after and touched by other men, but is it because of the effect it has on MC? Or does she enjoy that for its own sake, and the games with MC are an extra? Does she truly love MC and just have an immense fetish for these netorase games, or is she just getting off on playing with his emotions and libido while she engages in dangerous sexual games?
@SexPervert I completely agree with you. It's not often that we see female characters in hentai taking charge and being aware of their limits, especially in the NTR genre where corruption is a common theme. However, the latest chapter hints that Hinako is slowly losing control and giving in to pleasure. It's certainly hot to see her pushing her boundaries with other males, but I can't help but worry that the story might eventually lead to her complete corruption, following the usual trope found in other NTR works.
