``Mao'' is secretly popular with her mom's friend's husband because of her big butt, plump breasts, and above all her cute smile. Taking advantage of her remaining motherhood, she opened an adult entertainment industry at home called “Adult Kindergarten”! Husbands who are in a period of boredom say, ``It's easy to come and have fun'' and ``There's a lot of 'learning' that you can't experience as a wife!'' Pampered, played with, praised, and even a little scolded, a man's curiosity is satisfied with her erotic body.
