MDR

The MDR (Munson Dry Rub) describes a sexual technique where the penis is placed between a woman's breasts and a humping motion ensues. Hence the name, this act does not include lubricant and often leaves a long red mark extending from the cleavage to the collar bone.

After giving Kristi an MDR she had to where a turtle neck for an entire week.
