A husband in a sexless marriage checks his wife's phone and discovers that she has been cheating with multiple well-endowed men. Furious about his own modest size, he buys erectile-performance drugs and uses the resulting erection to force himself on Minami in an attempt to reclaim her. She tells him to stop and not touch her, but he penetrates her anyway, making her moan and writhe in ways he has never heard before. The scene is framed as his drug-fueled sexual punishment for her infidelity.
