The Girl's Guide to Depravity - The Vibrator Rule

Richard cancels a date with Sam, who complains to Lizzie that she's tired of the game men and women play with one another. Lizzie suggests they find a place where the guys don't know the rules, and settles on a Mexican place on college night. The girls pick up Stevie and Len, business/finance majors, and go back to their place. Lizzie and Len have sex, but Stevie is so excited he comes before Sam can even get him undressed. In the morning, the girls discover that Len and Stevie are both just barely legal and living at home -- they graduated from the "University" prep school. Meanwhile, Jason is romancing Nicole, a marine botanist who picked him up with a candid line at the farmers' market. Thanks to Lizzie, he has some doubts about her sincerity, but Nicole's directness wins him over. He goes out with her and they end the night with an energetic sexual workout. In the morning, Nicole leaves, promising to call Jason. A few days later, he bumps into Lizzie and Sam at the farmers' market. They see Nicole using the same "candid" line on another guy, and Jason realizes that Lizzie was right -- fake sincerity is Nicole's game. Jason and the girls adjourn to a nearby joint to drown their sorrows.
