In the heart of her private bathroom, she stands, the shower water cascading down her body, but it's the sound of shampoo being worked into her hair that truly excites her.

Her fingers work through her hair, the sound of her fetish filling the room, her body responding to the rhythmic, lewd sounds of her shampoo session.
