Movie description: The Surgeon General has just heard rumors that getting laid is good for you, and he's furious. If the general public learns that fucking is good for everything from headaches to depression, no one will need doctors anymore! To verify these rumors for himself, he assigns his two best doctors, Preston Parker and busty blonde Kagney Linn Kater, to do a little experiment for him. Kagney starts by stripping down and teasing Preston, then checks his heart rate for a reaction. Preston licks her pussy and tight little asshole, and Kagney's heart starts pumping just as fast as his own. Kagney gives his dick the royal treatment, sucking it and wrapping it up in her beautiful big tits. The horny docs fuck for science until Kagney is moaning with pleasure and her pussy is dripping wet, and then Dr. Parker finishes the entire experiment off with a huge facial!
