Intimate Touch (2001)

Debra is the new intern assigned to the mail room of a large corporation. Megan and Brittney are the veteran mail room employees assigned to train her. As Debra learns to sort mail, Megan and Brittney answer her occasional question, but spend most of their time drinking coffee and sharing erotic tales about various employees in the different divisions of their corporation. It seems those two girls have all the dirt on who's doing who at the office.
