It was an amazing feeling, we were doing some no-gi grappling at my MMA class, and I had started off with a single leg into half guard, but my opponent had a really tight grip on my leg, so I started working from an Americana to either get the tap, or to distract him so I could slip to side control. I managed to get to side control, but I kept hold on the Keylock to get the tap. Instead, he started to roll away from me on to his side, and I threw in a hook and took his back. I managed to straighten him out and get the other hook in, and put in a rear-naked choke. It felt good getting my first succesful submission after a month and a half of getting decimated xD Post some stories of your first submissions too!
