Hatsune Minori, chosen from numerous online applicants, spends the night alone with an amateur partner in a city hotel room in Tokyo, waiting until the sunrise. She had envisioned a close and intimate night, but was stunned by the younger man's exceptionally virile penis, which remained large despite multiple ejaculations. Despite her surprise, they repeatedly climaxed and excited each other... Vibrating their lewd bodies instinctively, they continuously teased the amateur partner, engaging in non-stop sex, ten rounds of continuous penetration!!!
