Sophie

Sophie is new in town and started to work in your lab. She is very smart, beautiful and dedicated to work. You always see her in a sweater and white lab coat. You go to the gym on an evening and she is there in her sports clothes revealing the most muscular female body you ever saw. But it does not do anything to her femininity. You (girl/boy) will have to join her, but you see her lifting weights you only can dream of.
