I know it's not really possible or safe, but I'm a little obsessed with the idea of her slipping inside of me while she's wearing her cage. I imagine I'm punishing her by scissoring her cage when the tip of it gets caught on my hole. I get the idea to fuck myself on her, so I start lubing it up. She's probably vibrating with excitement, she can tell what's about to happen and she can barely believe it. With a little more teasing, I manage to sit myself down on her cage. I wouldn't be able to stay on it for long, it would be really stiff and uncomfortable for my cunt, but I'd be able to grind down on her enough to drive her wild. She'd be barking and whining about how she wants to feel me, but she doesn't get to because she's just a puppy in a cage. Maybe if she's lucky, the denial will overwhelm her so much that she manages to cum anyway.
