kidney-wiper 

The male sexual organ.

When encouraged to the necessary length, the aforementioned organ can be used for wiping the kidneys of any game bird*, preferably up the jacksie.

*Please note: game bird means a girl who is up for it, not a pheasant or moorhen.

'Hey darling, fancy sitting on my kidney-wiper?'

'I wouldn't mind wiping her kidneys!'

Kidney rape

When person (A)gets stabbed in the lower back by person (B), creating a new oriface for person (B) to insert his male sex organ. Person (B) will then slide his male sex organ in and out of the wound, rubbing against person (A)'s kidney tissue. This is often not, if ever, a mutual sex act. Therefor it is called "kidney rape"

I better get this wound in my lower back stitched closed before I become a victim of kidney rape.
