text: give me a premise for a short story about a beautiful but shy college woman Emily from a conservative upbringing one summer getting an opportunty work for an well known painter. She work for him for a while before discovering he used unclothed models in the past and volunteers to do that also to secretly accomplish one her fantasies. Once she poses unclothed she discovers that she loves the freedom, empowerment, sensual feeling it gives her but with each session she fights to overcome the guilt, embarrassment and the feeling of vulnerability she gets from doing it.  Eventually she overcomes them and volunteers to work with other artists as she gets addicted to the rush she gets from modeling. The artist has a glass walled studio in the middle of a garden on this estate. He is married and very professional but playful and kind when he works. He cannot have a relationship with models but has empathy for them as a friend and helps them overcome their mental obstacles.
