Unable to satisfy her overwhelming sex drive through masturbation, busty newlywed Hikari reunites with her ex at a class reunion while her husband is away for three days. He taunts her about whether her current husband can truly satisfy her, and she brings him home for nonstop sex. She crosses every boundary as her ex repeatedly creampies her, aphrodisiacs trigger orgasm after orgasm, and a final drug-fueled session sends her completely over the edge. They finish by admitting their sexual chemistry is still unbeatable.
