I made this over a month ago as a gift for a friend. No need to name him really, he already has seen this, the wips and etc.

Always loved the ''pole between buttcheeks'' thing, like really is pretty hot specially when that ass is big, and with a butt like Mary's.
However I consider this a non-canon drawing, because according to Mary's personality, she doesn't do this kind of stuff.

This is a once in a lifetime drawing. Casual lewdness.

Hope you like.
