After a couple of hours at the party and a few drinks later the host invited Doug & I to join him in one of the rooms. When we entered I knew what I w...s in for. There at the far end of the room was what I would describe as a wooden stock for holding a head & hands so one couldn’t escape. At the bottom was a small platform with bindings to hold an ankle or foot. Our host smiled at me and said he’s heard from Doug that I enjoyed physical pleasure. Smiling I said yes I did.

I continued sliding my cock in slow, short strokes in.
