As the title suggests, this work shines a flashlight-like spotlight on men and women having sex in the dark. The darkness is an environment where one can expose oneself and have sex freely, while the light exposes oneself and evokes shame. This ambivalent situation of hiding and exposing creates a raw, tense, erotic sex that is quite rare these days. The women who appear are shy, but their love juices start flowing intensely and they all get excited right away and have sex in earnest mode. A new erotic genre has been established here, ahead of the rest!
