On a business trip, Rin is deliberately assigned a shared hotel room with the sexually harassing boss she cannot stand. He crawls into her bed at night and penetrates her, then holds her close while slowly thrusting deep. The pleasure becomes so intense that she gushes uncontrollably. In a single night, their bodies are drenched in saliva and pussy juice as he keeps fucking her endlessly in the locked room, turning their hateful relationship into one of overwhelming pleasure and ecstasy.
