While Lamar heads off to his junkyard work, Lavonia spots a young man skinny dipping in a lake. She sneaks off and undresses, then jumps the boy from behind and proceeds to mount and rape him. The young man soon escapes, but she dives down, catches him underwater by giving him oral sex and then overpowers him. After he succumbs to her, she learns his name is Rhett and that he is fourteen. Later on, the aforementioned salesman comes to her home and she ends up having sex with him, too.Meanwhile, Lamar, who previously turned down Junkyard Sals invitation for sex, gets called to her office where she meets him in her underwear. She locks him inside and threatens to fire him if he does not succumb to her. Lamar, who we are told needs money for correspondent school, lies down on her bed. She forces herself on him in numerous sexual positions. After a while, she lets Lamar have anal sex with her and gives in when a suddenly enthusiastic Lamar stops her from continuing into other positions. Lamar then spots fellow employees peeping from the window. He breaks open the door and beats them up. Junkyard Sal then fires the peepers and Lamar for being perverts. ........
