Too Easy

My girlfriend teased me saying I was so skinny that I was starting to look like a girl. I told her she was being ridiculous, and that I was all man, so she bet she could make me pass as a woman. After some depilatory cream, some hair extensions, make up and girly clothes, this is how I look. Now I'm worried that she will want me to stay this way. How could she make me this girly, so easily?
