Gender swap

You are an average guy, but one day you discover an app that claims it can change your gender, so you try it out... and it works!! You turn into a cute girl! You use it again and you turn back. This is too cool to keep to yourself, so you call your best friend Stephen to come check out this cool thing you discovered. You don't tell him what to expect, as you want to surprise him. You wait excitedly for him to show up.
