A cage that completely pushes your dick into your body

Alice carefully looks over all the unholy items in the drawer. She watches your face for any reaction, making sure she gets the one that will torment you most. After glancing over the many items in the drawer, she eventually decides on one you do not recognize and have never seen before. You doubt this means it is any less diabolic though. Alice picks up the object and crawls onto the bed with you. The smile on her pretty blonde face is enough to scare you shitless.

She takes the object and starts to unfold parts out of it. The first thing that comes out is what looks to be a dildo coming out of the back of it on a long bit of leather. This dildo is REALLY big, it is at least 5cm in diameter and 12 inches long. She looks at the dildo for a second and slowly licks right down it. "I'm not that cruel", she whispers, "I'll at least lube it for you", Alice rammed the dildo right up your ass and you scream in pain. You have never shoved anything up your ass before, let alone a 12 inch dildo. Alice watches a tear roll down your cheek and you can tell it makes her enjoy this just a little bit more.

Next, Alice unfolds two little bits out of the area just above where the strap came out of the object. These two little circular areas had little screws coming into the middle of the circles like what you would see on the base to a christmas tree. It didn't occur to you what she would be doing with these, until she was crushing your balls with the screws. Each of your two balls was stuck in a tiny little circle area of this object, and the screws were pushing them in from all sides. It was like being kicked in the balls, but it was a constant, never ending pain. You have gone into shock at this point, you can't even scream after all she has done to you.

Alice isn't even done with your balls yet, she presses a button on the object and it rams your balls back into your body. It has completely pushed your ball sack backwards and damn did it hurt. Your tiny balls are now squashed between a heap of sharp, pointy screws, and are pulling on the skin of your ball sack in the way ball sack skin was never meant to go. Alice is loving every second of this and is laughing at the way you are fighting your bonds trying to escape her. "This isn't even the best part", she coons, "after I'm done with your tiny little shrimp dick, there are inbuilt tasers and vibrators in this thing. I can shock your balls when ever I like. And I like a lot".

Your last shred of masculinity is in your dick, and you can tell she is going to be coming for this dick next. The last part of this object has finally been unfolded, and it is a metal tube about a centimetre in diameter and about 6 inches long. It is tipped in a metal flap that connects to the rest of the object. Alice takes hold of your dick and pulls the foreskin back. She caresses the tip of your dick for a few seconds, watching you for any reaction. Then she takes the pipe, and shoves it right down your urethra. It feels like a fire burning down the inside of your dick, an object that big was never meant to be on the inside of your dick. With a look of pure satisfaction, she forces the pipe all the way down to your dick and then a bit further. The rest of the object follows your dick down as it folds in on itself. This object then flattens itself against the bit of metal already flush with your body that is holding the dildo in your ass and your balls inside your body. There is now nothing but a flat bit of metal where your once proud cock was and a tiny whole you can pee out of.

Alice looks really satisfied with her work and one look at your face could tell anyone that she had done a good job of torturing you. She crawls up the bed close to your face and gives you one quick kiss on the cheek and whisper, "enjoy" before getting up and walking towards the door. Before she opens the door and leaves, she takes out her phone and sends a sharp jolt of electricity through your balls. This is by far the worst pain you have ever felt and you want nothing but for it to stop. She blows you a kiss as she walks out, leaving you tied to the bed in nothing but pain.
