When she studied abroad in the United States as a student, she was fascinated by the intense sex she saw in Western porn movies. Her first sexual experience was with a foreign boyfriend she met while studying abroad. His sex was so intense that she still remembers it. His penis was huge and it hurt, but the pain felt good and she can't forget it. After returning to Japan, she got a job at a language school. Her husband is a firefighter she met through a friend's introduction, and she expected that a firefighter would be intense, but it wasn't enough. During her frustrating days, she discovered adult videos and applied for them herself, seeking the pleasure of being penetrated deep inside her vagina.
