thumb locker

Two small natural holes on the lower back of the girls.

When you see the girl lower back from behind, there might be two small holes, which will fit the thumbs of the hand if you grab the girl around the waist. That will lock the thumbs from sliding on the girls back. Thumb locker will allow the person holding the girl's waist to hold her firmly.
