A sudden downpour strands the narrator and newly hired adult coworker Ozaki, forcing them to share the last available hotel room. Her rain-soaked clothes reveal her underwear and excite him, and he forces penetration despite her initial resistance. Once her desire takes over, she repeatedly begs for his cock and rides him hard. Their sweaty all-night session features relentless orgasms, uncut climaxes, creampie sex, and five ejaculations by morning.
