2×1 (1998)

Noriko Yoshifuku is sick. She hasn't gone to school in weeks, so a concerned teacher tells two of her male classmates (Satoshi and Junichi) to see her and drop off some class notes. When Satoshi and Junichi get to her house, they are surprised by what they encounter. Somehow, Noriko had blossomed into one hot-blooded young woman with uncontrollable sexual urges. Can the two guys cope?
