Rimu's boyfriend, Ichiro, was troubled by his persistent erectile dysfunction during sex, always only half-erect. One day, he witnessed Rimu being approached by a man while they were waiting for a date, which caused a strong sexual stimulation in his lower body. Realizing his NTR (being cuckolded) desire, he asked his friend, AV actor Kenji, to help him "steal" Rimu away for sex while he was fully erect. He arranged for Kenji to have sex with Rimu, with Ichiro secretly observing. However, the content of the recording may vary depending on the distribution method.
