Spelunking

The act of engaging in any form of rectal/anal penetration both medically or sexual in nature.

I went to my monthly physical, and my Doctor spent a good amount of time spelunking during his time below.

Last night my girl let me go spelunking for the first time in months. It was a rough time going deep in there.
