Iroha Morinaga, 38, is a marketer at a famous foreign company. Elegant and highly capable, she ranks among its top performers. She married a coworker at 30 and appears to lead an ideal life, but sex vanished from her marriage soon after the wedding. After discovering her husband's visits to sex workers and fighting with him, she could no longer bear his touch. With a strong libido that masturbation alone could not satisfy, she decided that if her husband could cheat, so could she—and chose to appear in porn for the first time.
