Your little son keeps peeing all around the house whenever he wants to, like a dumb untrained puppy...maybe those pet training sessions are messing with his brain, but not enough to become an obedient boy: the couch and the carpet get stained when he sits to watch cartoons, and you keep finding his underwear and toys scattered everywhere, even in the front yard...

That's why you bought the tiniest chastity cage you could find in the market, it's time to teach your pet-son who's the boss.

Additionally, you have crafted and attached a little "pee sensor" to it, using some wires and tricks that will shock his little dick if he dares to pee again when he's not supposed to.
