Mother Lovers Society 11.

Lily is not what she seems. She's sweet and innocent on the outside, but devious and conniving on the inside... worse, she's bored. So when her Mom, Krystal, drags her to the yearly Mother/Daughter weekend she decides to play a little game. With the help of her friend Tabitha the pair set forth a chain of events that have Mothers sleeping with Daughters and the two naughtiest of girls getting theirs in the end.
