Cathy's husband is disgusted when she suggests anal sex, but she finds not only solace in the arms of her work friends, but the possibility of revenge for his offensive remarks. Encouraged by the fact that both her friends have enjoyed anal sex with another of their work colleagues, Buddy, the three women plot a way to help Cathy enjoy the fun she's missing out on, plus humiliate her husband into the bargain.

If they can show him how enjoyable anal sex can be, and he manages to mellow, perhaps Cathy will forgive his insults. Or perhaps she will no longer care what he thinks.
