Cumming in Chastity

You are put in this cage and told not to take it off, but you really want to cum. you're not allowed to jerk it, that's why you are in a cage! what if you could keep the cage on and cum anyway. you'd still be obeying, you'd keep the cage on and not actually jerk. just because you have the cage on doesn't mean you cannot get off. let's brainstorm, what ways could you make yourself cum? humping is a good idea! you can hump all kinds of things, could you cum like this? what about touching the skin that isn't covered by your cage? maybe if you lubed it up and touched around it you could cum. maybe you need something else to make yourself cum, i am sure we can figure something out.
