During a company retreat at a hot spring inn, my normally serious office lady colleague gets drunk and mistakenly enters my room. Intoxicated and uninhibited, she becomes bold and takes the initiative. One after another, I'm overwhelmed—in the room, the banquet hall, the outdoor bath—she submits her body while drunk, licking, being fucked, creampie after creampie, as lewd incidents keep unfolding. Under the guise of a company trip, we spend a wildly depraved night together.
