Yoshimi Miyazaki, 38 years old, a housewife married for five years. This was her first experience on a sleeper train and with a man other than her husband. With nervousness and anxiety, the train departed. She writhed her sensitive body, which she had been trying to satisfy through masturbation, and pressed it against the window, indulging in sex. The next morning, she washed her body in the shower room and was played with by a vibrator again, taking the penis into her mouth once more.
