I just got done with my chores when master motioned me to his office. Once there he had me stand behind his desk. That is when he turned on the monitor and it shows me in the dungeon the night before. I froze and knew I had been caught. Trying to play dumb. Studdering "S S sir I am sorry I thought it would be ok since I had the night off. " I began to turn red some how watching myself on the screen I got hard and master noticed. He then reached in his drawer and pulled out this sheath and fit it tightly around my cock and balls. This allowed my cock to easily get hard and stay that way. But prevented me from cumming. It did have a small hole on the end so I could pee.

I smiled when master said and old friend was comming back. I thought at first was going to be andrea but he said it was subservient. "That is good master I remember she was real nice." My cock started to strain against the sheeth thinking about her. I told him yes sir and went back to my room. Over the course of the weekend I would try stroking my cock only to make it strain harder but not get any pleasure.
