Two married women, weary of mundane daily life and questioning their marital bonds, seek not affairs or casual sex, but rather extreme stimulation through exposing their acts of defecation. Manami is a perverted wife who enjoys stimulation of her clitoris, vagina, and anus, uniquely combining masturbation with defecation. Saki, on the other hand, was previously influenced by an ex-boyfriend who introduced her to anal masturbation with vegetables—a deviant fetish she keeps hidden from her husband. As their desires intersect, the shocking revelation of their first defecation and taboo sexual habits creates an intense, must-see encounter.
