The Bako Bus 2025 champion, crowned after thirteen ejaculations, receives the ultimate reward: a private overnight hot-spring trip with angelic porn star Kashiwagi Konatsu. It begins with affectionate full-body contact in a mixed bath, followed by smiling nipple licking and handjobs. Then comes the long-awaited private sex, with Konatsu's extraordinary attention keeping him ejaculating, recovering, and getting hard again. In the series' traditional reverse nighttime visit, she gives him no chance to sleep and fucks him through the night. Can he break his ejaculation record, and who will win this prize next year?
