My mother's name is Mariko. She's 39 years old this year, but she's always sexy, kind, and has such a beautiful smile—I truly consider her an amazing mother. Her daily routine includes cleaning and cooking, and after her bath, she does stretching exercises. She believes flexibility is the secret to good health, so every day without fail, she starts stretching in just her underwear after her bath. Seeing her like that makes me feel a little embarrassed, but I can't help it. This is the embarrassing secret of our household, and the story of my mother.
