Taphel's manga / #oneshot(234)

But I think I remember a yaoi where the uke kept being kidnapped and raped throughout different stages of his life? What I remember most clearly is that he was kidnaped during high school and constantly bound and raped for a few weeks and when he was freed he was so used to the constant sex that he was desperate for it and the manga ended with him going looking for the rapists again (in a public bathroom?) and the rapist going 'I told you guys so,'.
