One female novelist uses an unusual method to write her manuscripts—she has sex with company employees and part-timers to create vivid erotic scenes. When irritation builds up, she straddles a handsome, muscular male worker and rides him fiercely, losing herself in waves of sensual pleasure. Another female writer is obsessed with finishing her work by masturbating while indulging in wild fantasies. Her penis stands erect, and anyone who approaches is scolded with "Stay right there and watch!" Will she end up having sex with the teacher who's addicted to masturbation?
