Saeko Shirai is 35 years old and a full-time housewife in her seventh year of marriage. She has a family of three, including her husband who is an office worker and her daughter who is a student at a private school. "It's an escalator, so I've been doing it since kindergarten." After graduating from Aoyama Gakuin University, Saeko worked as an office lady at a foreign trading company until she got married. She is bilingual and fluent in Chinese. Currently, she enjoys her hobby of yoga while busy raising her child. Her only worry is her strong sexual desire.

She likes sex that gives a sense of freedom, so don't miss the sight of her shyness in her first shoot, but gradually becoming bolder!
