SOD Sex Science Lab: As a company involved in sex, SOD’s own institute studies eroticism, aiming to develop the sex industry and expand sexual knowledge (helping to develop products and services, and disseminating information to society to revolutionize sexual common sense). This time, the theme is “Eating Semen.” A female SOD employee who still has a negative attitude toward semen gets teary-eyed as she explores ways to eat it, such as by bukkake and as a dip.
