Cow Hypnosis (gxg)

A girl had a friend that turned into a cow. However there is some side effects to it. One of them is that they'll stay as a cow forever. Most importantly the important side effect is that after you turned into a cow, you'll also turn human with cow tail and ears. Then you'll be very needy for about 7 weeks once every month.

What happens if the girl goes to the hypnosis store?
