Dr. Kaede is a young counselor and a leading expert in penis medicine. She uses her knowledge and her body to treat (slut-teasing) troubled men. She sees through a patient with erectile dysfunction and uses mommy play to make him get a rock-hard erection and lead him to a premature ejaculation. For a patient with a peeing habit, she uses a drastic treatment to make him squirt. Dr. Kaede herself suffers from an insatiable sexual desire, and she and other patients with the same problem end up climaxing over and over again.
