On the first anniversary of her husband's passing, Yurie visits her parents' home and reunites with her younger brother-in-law, Akira, for the first time in a while. With her parents away, she accepts Akira's invitation to stay the night at their house. Seeing Akira's familiar cheerful smile, she begins to see the image of her late husband and can no longer suppress her emotions. Overcome by desire, she whispers, "Maybe I'll stay the night." Driven by uncontrollable lust, Yurie heads to Akira's room while he's bathing, presses her soft, big tits against him, locks lips, and hungrily swallows his saliva. Yielding entirely to instinct, she surrenders herself to pleasure. In that moment, past and present blur together, pulling her into a whirlpool of new, forbidden emotions.
