"I told my husband I was on a business trip today so I went out," says Shingu Kasumi, 46, with a beautiful face and slender figure. She is a hard-working wife who works as the sales manager for a foreign company. She and her husband have been married for 20 years, and they share the housework and childcare responsibilities equally, but she doesn't seem interested in retiring to the home just yet. "Right now I want to aim as high as I can," but this ambition has caused a rift in their married life. "At work, there are business meetings and study sessions, and when I get home, there's so much to do... before I knew it, we were sexless." She says she didn't have the courage to have an affair, so all she could do was distract herself by having sex alone. This shy business wife, whose obscene fantasies never stop even at work, experiences the pleasure of another man's cock for the first time!!
