two in the rung and one in the dung

Inserting two fingers into the vagina while another finger is in the anus.

In most cases the index finger and middle finger are extended while the ring finger and thumb are curled and the pinkie finger extended.

Have you ever put two in the rung and one in the dung
Yeah to my ex she went crazy for it!
Two for the pink, one for the pink I always think!
