Joan grows tired of the clingy Marcus and plans to break up with him, but only winds up complicating the situation by having ""pity sex"" with him. The girls try to help her out by bombarding Marcus with negative facts about Joan in the hopes that he will dump her. Meanwhile, Maya gets involved in a get-rich-quick scheme.

Joan decides to waive her ""three-month rule"" and sleep with Sean, but finds that the results are extremely disappointing. She seeks her friends' advice on how to help Sean improve his performance. Maya, with help from Toni, seeks medical attention after she and Darnell have difficulty conceiving a second child. William keeps having the misfortune of approaching every time Maya is discussing her gynecological situation with one of her friends.

On her 30th birthday, Joan grows depressed at the realization that she hasn't had a lot of excitement in her life. She determines that she will live life to its fullest in her thirties, and demonstrates her new philosophy by taking her friends to a nude beach--where they run into her father. Meanwhile, William suggests a pre-nuptial agreement to Yvonne, and is surprised by her response.
