text: give me a premise for a short story about a college woman from a conservative upbringing one summer discovering that she has love for being unclothed as an artist model. Include her working clothed before her offering unclothed after discovering the artist (painter) used nude models in the past. The artist has a glass walled studio in the middle of a garden on this estate. Once unclothed she discovers that she loves the freedom, empowerment, sensual feeling it gives her but with each session she fights to overcome the guilt, embarssment and the feeling of vulnerability she gets from doing it.  Eventually she over comes them and volunteers to work with other artist as she gets adicted to the rush she gets from  modeling.
