"The first time I masturbated was right after I entered elementary school..."Sayoko Ninomiya, 46, laughs as she says she was curious about sex from a young age. "I didn't know it was called masturbation until I was in junior high school." She invented a unique method without anyone teaching her. "I use a towel on the floor..." And it's surprising to hear that she still does it this way almost every day. "I look quiet, so most of the people I've had sex with are surprised." It seems that Sayoko is quite a slut. "I've cheated on about two people since I got married..." The fact that she talks about the number of people, not the number of times, makes it even more interesting. "I thought now would be the time to appear..." She has been married to her office worker husband for 20 years and contacted us to say that she would like to appear in a video before she turns 50. "My favorite male organ is a thick, round penis like a 0-series Shinkansen (lol)." A dirty documentary of a cute wife who doesn't look like she has a college-aged son is ready to be released!
