The rent on Valerie's apartment is high so she decides to advertise for two roommates, and decides on 25-year-old Sarah and 19-year-old Linda. The three women get on great, until Sarah and Linda get sloppy and neglect their household chores. As an alternative to finding someplace new to live, the roommates agree to a discipline regime where two of them will administer a bare-bottomed spanking to the one who has messed up. The idea works well in practice, and the girls get creative in their punishments with hand, paddle and hairbrush, plus added factors to heighten the embarrassment of the one being disciplined. Over time, Linda and Sarah move out, yet the spankings continue both at home and in the sorority... and there are hot bottoms all round.
