If you liked the Nozoki Ana manga, the Anime-Planet community thinks you'd like:
Hideo Aiba is anything but popular. Not only is he a high school virgin, he's also a part of the "Roman Club" – a group of guys with bizarre fetishes. But Hideo's unusual school life is changed forever when the mysterious Kurumi transfers into his class, joining the Roman Cub soon thereafter. Together, the two begin a strained and pleasurable relationship where Kurumi controls Hideo's very desires... and actions.
Two titles that deal with mature fetishes (voyeurism and S&M type stuff), which are quite explicit. If you liked one, you'd surely like the other.
I like to think Nozoki Ana as a lighter version of Sundome , I find both MC characters really similar and in both series MC girl manipulates MC boy , Most of the time ending up in sexual situations.
Another great pair of manga that probe the depths of human sexual depravity as a way of looking at love and relationships. The unequal power dynamic (female over male) and explicit art in both will make them enjoyable for the lover of either one.
On the surface, Nana Chigusa appears to be a typical honor student, loved by the student council and her peers, and surrounded by admirers and friends. But deep down, even good girls need a way to blow off a little steam and de-stress, and for Nana, that means secretive, intense S&M sessions with Kaoru, a well-known pervert and her childhood friend. What experiences and pleasures await this unlikely pair?
Two explicit titles that revolve around mature fetishes, with elements of S&M and/or control/power over another (Nana to Kaoru more so). If you liked one, try out the other.
Both series are about sexual secret that boy and girl hold and even people Who interrupt in their live are similar in "Nozoki Ana" and "Nana to Kaoru" if you like this manga then most probably you will like the second one.
They both cut very deeply in the ecchi/mature theme genre but they are well made or better said well written. It's been so much fun reading them they cover a romance-lovestory in a kind of "hentai" way but still got coverd the story... just check it out and you know it certainly isn't something for everyone but I'm sure there are people out there which will like a good laughter and a pretty unique story handling.
Check them out they are worthwhile.
When Akiyama booked a vacation for him and his girlfriend at Koibana Onsen – a place known for helping unite couples both mentally and physically – he had no idea that they’d break up days before the trip.

Same Author, Same Fetish, Same blackmailing girl
Enough reason to read other if u liked one, only difference is Adult content in two series NxK being in highschool has echii content while NA being in college has lot of sex scenes and other adultery making it borderline Hentai.
Story and character wise,both are almost same with main characters resembling each other in even looks
