8 XXX : ConfusedBoners

I have never LITERALLY been confused by my erection until this moment
That may be the most satisfying thing I've ever watched.
I didn't even notice which sub this was in, watched the whole gif, then thought to myself "why do I have a chubby?"
This is CNC (Computer Numerical Controll) Machining of what looks like Aluminium components. The reason i know is because this is my job, a CNC Machinist, this is a particularly appleaing gif to watch and not often do we make such smooth and delicate parts, but it is done from time to time
Does anyone know what they are making?
Couldn't stop watching it...
Can someone make me a buttplug like this?
Fucking mesmerizing.
Some sort of strange sex toy.

looks to be the plug in a Tema fitting, a coupling used in hydraulic lines to hook lines up to a trailer etc. Good for several thousand pounds of pressure. link : http://i00.i.aliimg.com/img/pb/929/320/547/547320929_357.jpg
