I created my own list for possessive SEMES since the tags don't really do it for me since I like them super possessive and most tags have cute mangas that aren't my cup of tea, so here's my list for the best this type yaoi.
Rape might be included, so be careful if that's not something you enjoy.
I’ve received some feedback that some of these stories are not possessive, but I’ve made that clear in the desc so skip those if you’d like!
