Wife Eriko had taken over from her parents and worked as a condominium manager. Beloved by everyone, she was nurturing and always devoted herself to helping others. One day, after resident Yoshiichi was apprehended due to a fight, he ended up injured. Unable to ignore his condition, Eriko not only nursed him back to health but went as far as bathing with him, displaying extreme caretaking behavior. Overcome with desire, Yoshiichi couldn't hold back—he touched Eriko's voluptuous body and quickly found satisfaction as she gently took him into her mouth. After that, Yoshiichi became obsessed with Eriko's attentive nature and grew dependent on her. However, their relationship soon caught the attention of her husband, leading to unexpected complications.
