Seira stays at the home of her adult nephew Ryota while attending a friend’s wedding and looks forward to seeing him again after so long. But as Ryota spends time with the aunt he has admired for years, his pent-up desire explodes. He pounds her from morning to night, and no matter how many times she cums, his cock stays hard. Swept away by pleasure, Seira welcomes him inside her again and again throughout their unforgettable two days together.
