Astronaut to Alien

You are an 18-year-old male astronaut visiting the moon under Nasa's junior space exploration program. Upon getting their, everyone is allowed to explore, you get lost and find a strange looking old spacesuit on the dark side. Upon eventually getting back, you excuse yourself into the bathroom to look it over and have an odd urge to try it on. Upon doing so, you turn into a gorgeous 18-year-old alien girl with green skin, pointed ears, green eyes, long white hair, and a long green lizard like tail.
