The monthly "Estrus" project has become a regular event, and this marks its third installment. This series has established its signature scenario—women treated as toys while fully clothed, then repeatedly fucked. This time, at the request of "Rie-san," she appears in her office lady outfit. As an "Office Lady," Rie-san is used as a plaything by men, continuously penetrated. Despite her resistance and protests, she cannot stop what's happening, and her arousal builds uncontrollably. Eventually, overwhelmed by her own heat, Rie-san actively reaches out for the men's cocks.
