Sir training my throat using an open mouth gag. Proper posture is ensured by the anal hook that is threaded through my collar and tied to my arms so that if I relax my arms or struggle I get choked and my asshole gets pulled apart
Sir got me an ergonomic chair to help my posture. But that didn't seem to do the trick so he stuck an anal hook up my ass and tied it to my collar with a strong elastic band. Now this is how I work... (As his secretary.)
