This boy had cuffed himself to the wall before I arrived using a pair of hinged handcuffs on his wrists and another pair of chain link handcuffs to secure the hinged cuffs to an eyebolt in the conrete wall. He had also cuffed his ankles with a pair of leg irons. Since he left the only keys to the cuffs on the other side of the room, this meant he was cuffed to the wall with no way get himself out of his predicament until I arrived, and later released him. This obviously takes a lot of trust, but he knew he could trust me.
I arrived about 15 minutes after he cuffed himself to the wall. I immediately removed the blindfold that he put on himself. I replaced it with a locking hood. The hood has removable eye patches and a removable gag. I also locked his dick in a Jail House chastity cage to prevent him from getting too excited while I played with him, since I planned to put him through quite a bit of teasing. He told me he really wanted to experienced being locked in chastity, and this was only the beginning of that experience. If I was going to leave later keeping his dick locked in chastity, I wanted to make sure he was sufficiently horned up first. <grin>
I played with him for the next few hours in various ways, including what was done with him in this post. Then I left, leaving him locked in chastity for a while. Since this was his first time being locked in chastity and I know that can be scary for some, I decided to leave a combination lockbox with him which had the key to the padlock on the chastity cage. That way, if he freaked out when the feeling of being locked really set in before I returned to unlock him, release could be just a phone call away.
