Probably not this but when you mentioned a "fucktoy" or a sex doll, I remembered this manga http://www.mangago.zone/read-manga/notpia/..kind of same plot. You can search it also in tags for you to find what you're looking for. (●'◡'●)ﾉ
Yeah, its similar but its not the one. Thanks for helping anyways. Here's some flying hearts to wherever you r
Yaoi manga between a teacher(seme) and student(uke). The teacher abducts/kidnaps the student and rapes him. I remember it not being the main story. the manga had multiple stories. The teacher and student was one of the stories. The teacher wasn't even the students teacher(he teaches second years i think) and the student was a first year. The seme even brought a dutchgirl(fucktoy) which he made the uke have sex with. Thanks in advance and if there are any good yaoi recommendation pls give em~
