Hiyori, her best friend, comes to her for advice about her husband's infidelity, which just won't stop. She confronts her husband in a rage, but her anger heats up when she sees no sign of remorse. "Your dick is so big that women are coming to you? If so, show it to me right now!" Hiyori forcefully removes his trousers and finds a rock hard cock that is bigger than she'd imagined. Her body starts to throb with this unexpected turn of events, and under the pretext of investigating the cause of his infidelity, she approaches him to get a taste of his hard cock.
