The Kugii couple cannot conceive because the husband’s sperm count is too low. Sunao’s ex-boyfriend invites her to a class reunion. At the drinking party her suppressed lust breaks, she crosses the line with him, then former classmates and a former teacher who wanted her gather around. They fuck her raw, creampie her womb again and again, and she asks them to get her pregnant with another man’s child while her infertile husband is left behind.
