Karen is suddenly abducted and taken to a secret brothel operating behind the front of a traditional restaurant. They begin conditioning her nipples so she can become the house's top attraction. Night after night, the training wears down her mind while making her increasingly sensitive, until she is forced into complete submission as the brothel's nipple slave. Word spreads and men line up around the block. Her nipples have become as sensitive as a clitoris, and customers torment them while repeatedly creampieing her. Many finish, get back in line, then return to penetrate and fill her all over again.
