When I was 25, I was in a D/s relationship with a dom who loved watching me be used by others. He'd lock me in chastity so I didn't have a choice but to make it all about others, and I loved it.

One night when I was on the way to his place, he sent me directions and told me to meet him somewhere new. I'd been locked up for a few days and was in no position to argue, so I happily followed his instructions.

Once we were together, he walked me into a dark and seedy cruise club. If I could have gotten hard I would have. I love the smell of leather and lube that so often goes with those venues.

He guided me to their glory hole booths. They had a split level so I could stand while I serviced guys, and it meant there was no way someone would try to get at my locked cock either (wouldn't want them to be disappointed).

He locked the door behind us and told me to put my hand through the hole and wait. While we waited, he opened his bottle of amyl and forced it under my nose. He made me inhale once, twice, three full breaths of it. By half way through the second one my head was already spinning, but the third hit I was straining in my cock cage and desperate for something to put in my mouth.

Seconds later, my first visitor walked by and pushed his cock into my hand. I was eager and got his hardening member into my throat immediately so I could feel it grow. Head still spinning, my dom held my head against the glory hole so I couldn't back up and started tweaking my nipples with his other hand. I was in heaven as the cock in my throat started slowly pulling out and thrusting back in. I did my best to hold off gagging but I couldn't help it. The guy didn't care and just kept on sliding into the back of my throat trying to make his way back down it. I would have cum in a second if I was allowed to, but I just had to stand there and take it. After a few minutes my head rush tapered off and I got my hands involved, massaging his balls and stroking his cock as it left my mouth. I felt his balls begin to tighten and his cock swell in my mouth so I took as much of it in as I could and swallowed every drop he had to offer.

The cock stayed through the hole for a while longer as it softened so I kept it in my mouth and cleaned it off as best I could. As it slipped away I was happy to have had my first load for the night, and my dom whispered in my ear "one down, four to go". I was in for a long night.
