I am in need of help finding an ecchi comic I found a long time ago. From what I remember, the main character was a relatively young guy who's very into shibari and bondage. he reads all the stories published by a particular erotic writer and eventually meets him. the writer invites the main character over to his house in the countryside or something to show him actual bondage taking place. the main character also has a girlfriend or something who ends up also going along with them and the writer and his submissive end up teaching the main character and his girlfriend about bondage. I can't remember much else about it, it was a collection of several chapters. pic is not related.
uhmm maybe can su try with, NANA TO KAORU is a good manga with bdsm and shibari
