Part-time employee Nanami always gives her manager everything she has. One night, after working until the last train, she deliberately lets them miss it. The nearby hotel has only one room left, forcing them to spend the night together. Nanami confesses that she loves him; her relationship with her boyfriend is failing, and the older married manager who has always cared for her is the one she truly wants. Unable to resist a woman twelve years younger, he has sex with her and cums repeatedly, forgetting his wife as they lose themselves in desire until morning.
