The concept was the uke's sex toy would be link to the seme's dick so when he uses it the seme can also feel, I really can't remember it huhu
I know a manhwa with same story but the roles are opposite ... The sex toy seme has is linked with uke's hole - "link in the hole"
i think i know this, but i forgot the tittle. is it this one? https://www.mangago.zone/read-manga/saeki_kun_ni_tsunagatchau/
no! wrong sorry its different. this one is the seme sex toy is linked witht he ukes XXX
I'm really hoping to find a yaoi/BL manga where there was past bullying particularly the seme being bullied by the uke and time skip uke falls for the current seme and seme take revenge, or anything similar to that trope, bonus if the seme is younger and possessive
