Aoyama Ao says she has always lived an ordinary life. She married a former coworker last year, but nothing changed: she still travels between work and home, and even sex with her husband feels routine. Afraid of growing older without ever taking a risk, she volunteers to appear in porn. She had turned down a talent scout in her adult student days because she did not trust the agency, but the idea never left her. Once pleasure awakens her, this supposedly ordinary wife transforms far beyond anything anyone expected.
