Yamato went abroad, dreaming of bringing his hometown’s cuisine to the world. Ten years later, he married a foreign girl and returned to Japan with her. Lily studied Japanese in college, dreaming of living in Japan. Passionate about Japanese culture, she pleased her father-in-law. But Lily was overly 'casual.' After bathing, she wore just a towel outside, and at home, she skipped underwear, her nipples fully visible to her father-in-law. Yamato, often abroad, forgot Japanese 'customs.' During sex, he’d just thrust and cum quickly, skipping foreplay, leaving Lily frustrated and unsatisfied. She always masturbated after sex with him. Her father-in-law saw it all. While Yamato was out, Lily went to her room, and he knew what she was up to. Catching his beautiful daughter-in-law masturbating, he stepped in to show her true Japanese 'culture.' He kissed and licked her body, teased her nipples with his fingers, fingered her pussy, and explored every inch of her. He gave her pleasure she’d never known. Lily bucked her hips, chasing orgasms, her mouth protesting but her body craving more. She sought out her father-in-law, begging him to play with her nipples, to give her the ecstasy her husband couldn’t.
