A sudden business trip with a troublesome middle-aged boss. A guerrilla rainstorm paralyzes transportation, leaving them with no choice but to drink and wait at an izakaya. However, Nagisa gets completely drunk. Faced with her wet, flushed, busty body, the manager can't hold back... She's pounded by the penis of the man she hates, losing herself in pleasure. Swallowed by a vortex of deep ecstasy, she turns into a beast, grinding her hips on her own. She gives him a deep, sucking blowjob and uses her voluptuous breasts for a melting titjob to make him even harder. He pistons deep into her womb, making her arch her back in climax. Unaware that morning is approaching, the two drown in relentless sex. Covered in bodily fluids, their intimate, clinging intercourse shows no sign of ending.
