The hand a person, generally male, uses to operate a
computer to browse pornography, whilst masturbating with the other. This is to avoid the spread of anything from the genitals to the mouse and keyboard.
The hand in question
will ideally never touch the genitals, and can therefore be used to click a computer mouse, or type on a keyboard, whilst keeping the desk and
computer area as hygenic as possible.
It took me ages to type
www.youporn.com, because I could only use my clicking hand.
My
mum walked in on me wanking the other night. She caught me with one hand stroking my bishop, and my clicking hand clasped firmly on the
mouse.
