You've been locked up for so long and I know you've been desperate to stroke your stupid little cock and since you've been so good, I've got a deal for you. It's pretty simple, you can ride it to the edge but you better not cum. Not even a little. As soon as you start to cum you let go. You can only cum if you aren't touching your cock. So keep pumping and stopping until you let go and a little squirt comes out. I know it was just a little and you're not done but I don't care, lock it back up, you're done.
