Bondage con nastro adesivo sulla sedia

I arrive at my office to work and out of nowhere someone ties me up and gags me with duct tape, on the heel, knee, thigh, waist, shoulders (between the breasts) and hands crossed behind me. I don't like being tied down until I start to like it and try to seduce him, he shows up again steals my belongings and leaves but thinks better of it and puts his dick in my mouth, I don't like it but I start to like it and soon enough he has sex with me in on top of the chair and cums on top of me.
