Dr. Monroe is used to seeing grown men cringe at the thought of getting their prostate exam. But she is not impressed when a healthy grown man like Mr.Pierce, is afraid to get his flu shot. He refuses to get his shot during the check up and Dr. Monroe has to take necessary action. She grabs the large flu shot needle, and sticks it into the cheek of her own ass. This backfires though as she has taken the wrong shot and injected herself with Libido. The toxins cause her to get sexually with Derrick as she takes his large needle of a cock for a ride.
