One day, a refreshingly lovely married woman, Mrs. Yamaguchi, unexpectedly contacted me saying, 'I want to have raw SEX.' When I asked, she said that she hadn't had unprotected sex for 11 years since her second son, who is now 10 years old, was born. 'It's a safe day, so...' she made an excuse to herself and finally crossed the forbidden line. Perhaps due to guilt, Mrs. Yamaguchi was initially restrained, but she couldn't resist the pleasure of raw penis and climaxed, her body trembling.
