Porny Monster(2007)

Chapel Waste is the ultimate Joanna Angel wannabe who appeared out of nowhere and begged to be her protégé. Angel took on the project, thinking it might be fun to have a little pet... but Chapel quickly rose to the top, and fucked everyone in all 5 boroughs... including Joanna's boyfriend. The innocent suburban poser developed a severe addiction to dick, and transformed into something Joanna Angel never imagined she would be... a Porny Monster.
