You mean the PA lock that interlocks with the PA in my dick? That is perfect for proper safety - making it impossible to pull out of the cage. You can buy cheap PA locks in lots of places, I have a titanium one from Steelworxx.

It was such a thrill to be fastened with chains, handcuffs and the neck iron and to be at the mercy of You, Master, and the dice ... 🥵

It's a remodelling of a HolyTrainer cage, specifically from the German EDD24 online shop, called "Femboy V2 Small". 😳

For a cheap model, it is remarkably durable and reliant - Master just had to file out the two air holes on the side a bit for the PA lock to fit through.

The most important picture element is front and centre, as it should be. 🤤👅

Being locked up in Your basement dungeon and being allowed to roll Your die before Locktober is even better than cake or dinner, Master! 🤤⛓️🎲

Oh, okay then, Master. 😢😏

Being such a musical doggo, I think we should try to have another concert very soon. 😇🎼🎶

I loved every second of it. Thanks a lot again, Master! Looking forward to the next session and letting you have your way with me! 🤤😇

I guess the cage had to be taken off for the stretcher and so you just used the free dick for some electro torture spontaneously. A very intense decision. 🥵🤩

... or another layer 🤔

Yellow is just such a nice colour, isn't it? And I'm not quite sure if I was in heaven or hell. I guess we need to repeat the process until I find out a definite answer. 😇

Yes, Master, I was quite helpless - even when the feeling of my balls being stretched or pressed turned into from a nice sensation into a prolonged pain. But I was glad to get such a deserved severe treatment. 🥹

Yes, Master, most definitely. 🫣

If it can fit a boy, it can easily fit a doggo. 💡
