Daddy's Shower Surprise

18 year old Mandy loves long hot showers. She loves the steam and hot water and the feel of her hands caressing her soapy body.
The only thing Mandy loves more is her Daddy who she fantasizes about in the shower, her bed, and everywhere else. 
One Saturday when her mother has to work, Mandy sees her daddy watching her by the pool. He heads upstairs to shower and she decides, why not join him?
