Yuika Onosaka has lived her life as a married woman. Although she's dated several men in the past, she's never had sex with someone she truly loved. Her first time happened when she was over twenty, after a night of drinking too much with a coworker. That experience left only a faint impression and a slight sense of regret. Since then, she's had relationships with men, but they were all one-night stands—never with someone she deeply loved. Now, she's happily married to a man she's serious about, building a life together. However, her husband has limited experience with women, and their sex life has been monotonous, rarely leading to real excitement. One day, by chance, she came across a video on social media showing intense, passionate sex scenes—and she felt deeply drawn to it. That moment sparked her interest in appearing in adult videos.
