Supergirl ["Kryptonite Cock Ring']

That title isn't a joke, it's the actual plot. Kara has an obsession with reproduction and loves being the bottom of her sweet human companion. But if she gets too excited, her super strength can turn a hot night into a total disaster. Introducing the Kryptonite Cock Ring: a handy little device made with black market kryptonite, weak enough to tame her powers and make her feel nice and submissive. Attach it to your strap on, your penis or whatever you have and get ready for some wild fun. Just pray it doesn't break, because death from Super Snu-Snu is a very real possibility.
