I have locked my slave inside the cage under my BDSM bed. I enter the room for just a moment only to quench his thirst. The cage has a special opening for the head so he pushes his face out, looking straight up. I spread my legs, place one foot on the bed and from about one meter high I piss directly into his open mouth. He drinks everything. I leave him there. I will come back later to feed him, haha.
