Eagerly awaiting her husband's company trip... Hiromi Shinoyama, 45, a housewife. She says she's been masturbating daily ever since discovering it on the monkey bars in fourth grade. After 21 years of marriage, she has sex with her husband only about once a month. "Masturbation has evolved so much for me that it feels better than sex," she admits. Yet, she confesses that sex with a partner still feels incomparably better than masturbating alone. Hoping to find a man whose stamina and virility could surpass her high physical expectations, she applied for this project. "I'd prefer someone with good stamina... I don't really know from experience, but once I get used to it, I might even be interested in threesomes," she shyly shares. Her highly sensitive, wet, and responsive body will be pushed to the limit—ravaged so intensely her legs will give out completely.
