Dung Beetle 

While doing a chick doggie style, you slip both of your thumbs (with thumb nails touching) into her butthole. With both thumbs inserted in the anus, you click your thumb nails together thus, making a beetle sound.

I was banging Sandy from behind and she actually requested I give her a Dung Beetle.
