So I just read Match App de Mitsuketa Goshujin-sama ni Jinsei Bukkowashite Moraimasu (542191). And I really want more kinds of doujins where a character (male or female, idc) willingly becomes a sex slave / makes a contract without any kind of mind control or the like being involved. I tried to search for more, but unfortunately there aren’t any tags that are particularly helpful in this case.
If anyone has read something similar I would greatly appreciate sharing the sauce
