Cassidy Lynn convinces her friend Natasha Nice to visit a seedy adult book store in the Tenderloin. What could possibly go wrong? The guys circle like sharks, the sound of sex from the movies fills the air as the girls are watching porn in their own rooms. The smells, the sounds all start working on the girls. As cocks start appearing in the holes the girls have little resistance left not to indulge their curiosity and play. What the girls don't realize is the doors do not have locks, and soon the girls are in over their heads with cock.
