this has hardcore bdsm tho so continue at ur own risk!
the manga is about sakurada who is an office worker and also a pervert along with his co-worker, mibu a really handsome guy and popular w the laides.
sakurada asked mibu to go for drinks together so that he can get with girls, but he got super drunk and he was brought somewhere by mibu.
later mibu revealed that he is actually a very popular sadist at a bdsm club and what made him like this was because sakurada as his senpai during highschool asked to grope his fat man boobs cause he was just THAT perverted.
sakurada was very surprised cause how could this hadsome man possibly be that one fat kid in highschool.
mibu now plans on developing sakurada's body into a submissive masochist.
Anything like "till our lips touch"*character were fat or ugly or what when they were younger* I've read other manga but I never had read other manga/manhwa that is colored
Recommend me some colored ones
