sadslime's manga / #Sister's boyfriend(1)

Shite Hoshii Koto, Oshiete Ageru.

Complete | Shiramatsu | 2019 released

Ren's a high school student in love with his best friend, but after waking up with his sister's boyfriend mistakenly entering his bed, he finds himself interacting more with Kazuya, who offers to "help him out" by touching him. As their relationship progresses, Kazuya moves from playing with Ren to feeling guilty for what he's done to him as he realizes he's causing Ren to relive his own trauma. This story is interesting, and I enjoyed it, but at the end of the day, there's no defending Kazuya as a male lead. Trigger warnings: noncon, cheating, rape, statutory rape.
