Monami Yuyu, the svelte office newcomer, finds herself in a shocking predicament during an out-of-town work trip. Paired with her hulking, lustful superior, Tkd, in a cramped hotel room, she's in for a night of unbridled debauchery. As the lights go out, Tkd's primal instincts take over, pinning Monami down and ravishing her with reckless abandon. Her protests turn to moans as he pounds her tight pussy relentlessly, filling her with his massive cock again and again, until dawn breaks and she's left breathless and marked as his territory.
