Mrs. Mirai (32) enjoys a stable married life and makes love with her husband every night, but they've been unable to conceive. Lately, she's grown dissatisfied with her husband's lukewarm sex. Her body aches with pent-up desire, and unable to endure it any longer, she plans a secret "honeymoon hot spring trip" with a 50-year-old male entrepreneur she met through a dating club, timed perfectly during her husband's business trip. What began as playful paid dating ultimately fulfills Mirai's craving for regret-free sex. Inexperienced yet passionate, he enjoys slow, sensual blowjobs. They start with mixed-gender bathing in an open-air hot spring, hungrily exploring each other's bodies. The bold acts continue—blowjobs leading to creampie in the bath, followed by passionate kissing, groping, cunnilingus, handjob blowjobs back in the room, soaking her completely. His slow, intense vaginal stimulation melts Mirai's body entirely, resulting in a full recording of unrestrained, erotic sex.
