It is not uncommon for women to squirm a lot during a Brazilian Wax. I had a woman recently who moved around so much that I thought she was going to fall off the far side of the table. Between grabbing me and closing her legs, the wax was extremely difficult for me to do. On top of it all, she had a piercing in her nether regions that I was afraid of removing by accident amidst all her gyrations. I asked her very nicely to try to relax and stop moving so I could finish. She said that is exactly what the guy said when she lost her virginity. He told her to lie back and relax and it wouldn't hurt so much.
