Chihiro Niikawa, 50, is a tall wife with a model-like figure, standing 175cm tall. She is a full-time housewife, the mother of two, and has been married for 15 years. Her concern is about her nighttime activities with her husband, whom she married through an arranged marriage. "My parents arranged our marriage when I was 35. I was at the last possible age to have children, so I immediately agreed. But with an arranged marriage, you don't get to know what goes on at night... I regret it now." Chihiro says that she has only had sex with her husband a few times since giving birth. "I just want to let it all out. I want him to thrust into me as hard as he can!" she says, full of enthusiasm!
