Friends With Benefits

When Ben is confronted with needing a date to his sister's wedding, Sarah begins to worry that their arrangement is becoming too serious. Their friend Aaron Greenway, a successful tech genius, is not quite sure what to make of Ben and Sara's complicated friendship, but he, along with the smooth ladykiller Julian "Fitz" Fitzgerald and the gorgeous, free-spirited Riley Elliott, are all distracted with their own dating trials and tribulations.

Ben and Sara choose to bring their physical relationship to a halt when Sara begins dating a co-worker who she thinks might be boyfriend material. Elsewhere, Aaron takes his relationship with Riley more seriously than she does and shows up to meet her for what he believes to be a dinner date, but quickly realizes things aren’t what they seem.

When Aaron becomes depressed over an ex-girlfriend getting engaged, Ben and Fitz decide to take him out for a night on the town, only to end up arguing over a girl. Meanwhile, Sara tries to befriend Riley and her wild lifestyle by hesitantly attending a party that makes her question her conservative ways.

Ben runs into an ex and reaps the benefits of her short-term memory loss. Meanwhile, Fitz fears his lesbian mother is lonely and tries to find her a girlfriend, but is surprised to find that she is already in a relationship. Elsewhere, Riley dates a man with a breast-feeding fetish. Dave Foley guest stars.Ben runs into an ex and reaps the benefits of her short-term memory loss.
