Blonde twink, locked in chastity

My sub who was named "Cumdump" according to his add rushed over to me carrying a simple black box in his arms. He was wearing a blue latex crop top and tight blue latex hotpants with a cut-out for his dick and balls. He also wore pads on his knees. Once he reached you he got down on his knees and raised the box to me. "Here is my collar sir, and my favourite item."

When subs wrote their add they could list their favorite fetishes, and would usually bring one item to represent that to their dom when they first met. In Cumdumps case, his fetish was to be kept in chastity by his owner, a fairly common fetish amongst subs, although most we're kept in chastity whether they liked it or not.

Cumdump had thus brought a metal chastity cage with its lock and keys attached and put them next to the collar in the box. The collar itself was made out of black leather with D-rings around it so I could attach his collar to several things around it if I wanted him to stay still. I lifted out the collar first and buckled it around his neck.
Next I took the chastity cage and keys and asked him to stand up. He did so and smiled shyly while I squated down to lock up his cock. He was so excited he'd gotten rock hard. "My my, this simply will not do Cumdump." I said and gave his balls an stern squeeze, making him yelp and his dick soften somewhat. Before the pain went away I quickly fed his dick and balls through the metal ring and then stuffed his dick into the tube and locked it all shut.

I stood up and hocked a finger through one of the rings on the collar. He was smiling, so happy to have a dom. I stroked his locked up cock with my leg, making him moan and wriggle cutely. "Enjoying yourself Cumdump?" I asked, he nodded. "Very much Master." "Follow." I ordered briskly and walked away with him in tow.
