Try the cage

The metal contraption may be very odd, but there shouldn't be any harm in it. Just put it on, open the door and get rid of it.

Putting it on is easier than you expected, somehow. For one thing, it seems to have been made for you. Each piece fits well, if rather snugly. As you slip the cover over your cock, you check twice to be sure you can take it off, but each time there is no difficulty.

Once on, it feels almost soothing, though it definitely bounces and pulls if you try to walk too fast.

No point in delaying this, you think. You tucking your shirt under your neck to keep it out of the way. You then insert the cock/key into the door.

Click!

You feel the lock close around your cock. Screaming inside, you try to pull yourself free, but cannot. Your panic only last for a moment, however, because then the door clicks and swings open, at the same time releasing you.

You find yourself on a largish landing above a stone spiral staircase. You reach down to remove the cage on your cock.

You stop in shock. A pair of steel rivets have been driven into the hinge. No matter how you push and pull, it will not come off.

Do you:
