While working at a company, she met her current husband and married him, eventually leaving her job. However, she feels emotionally unfulfilled. Her husband, a busy physician with an irregular schedule, leaves little time for intimacy. She occasionally relieves stress by attending concerts with a former senior colleague from work. In this situation, a married woman chatting over drinks at an izakaya is suddenly approached by a man. Letting her guard down, she ends up sucking two men's dicks, riding them in cowgirl position, making them cum, and discovering the intense pleasure for herself.
