The FIRE button

Femdom themed 3D audio (Binaural) test

I just can’t help myself, when I see some cool tech my brain goes wild trying to figure out the best way to put my perverted spin on it. Luckily 3D audio tends to go pretty well with kink. The main idea behind us doing something like this was for people who work in office’s or have commutes. You can pop your headphones in and have kink with you where ever you are.


I had to give it a go, and luckily I had a little bit of left over money for the month so invested in some recording gear (justified because it’ll be used in other things too)

As you can probably hear, I am no expert at this stuff. I know I buggered up my levels when recording. However for the first go I’m pretty happy. Looking forwards to having another stab at doing some of these




Nipple Cuffs

Not much I can say about these guys, best to just watch 🙂




If you want to download a set for yourself then you can Here


Fan cuffs – A fun little revenge toy!

Well this little toy all started thanks to this little tweet…



I just couldn’t help myself 🙂


A quick prototype of a BDSM stress position toy

This is probably my most unfinished toy but I had to share as it was so much fun.


The Tugger – Stretchy Nipples

This is by far my favourite way to use the Tugger!! Just look at the stretch on those nipples!

The Tugger – Leg Cramps

A quick video to highlight one way to use the Tugger. Miss K is forced to keep her legs high to avoid putting tension on the tugger. When her leg muscles eventually give out and her legs drop she starts getting shocked, this gives her enough encouragement to lift her legs and keep trying.

I really enjoyed seeing the exhaustion on Miss K’s face at the end of this one 🙂

The Tugger

So as you probably know I have a passion for predicament bondage. This toy ticks pretty much all of my boxes. It’s versatile and deliciously evil 😀

Chunky Chain Collar – Completed

The chain collar has been completed. I originally spoke about my design for this here. The chain was an absolute bugger to drill through. with lots of coolant I finally managed to get her drilled, Then I struggled again to do the counterbores so that the bolt heads were hidden. I tried with a step drill but it broke within seconds. in the end I did the counterbore manually with a pencil grinder and a carbide bit. It worked a treat!

I love how in real life it looks seamless. It has completely captured the sense of permanence and Miss K appears to love it too!
