"From today, I will be the baby of the family (everyone)" - A complete simulation! A spoiled and regressive life! Sara, the older sister, has a sloppy attitude and body. The family, who have been troubled by her continuous troubles, have decided to... re-raise her! ? "Sara, from today, you will be demoted to the second daughter and you will have to start your life over as a baby!" "From today, I will take good care of you, big sister... Sara-chan?" Taking care of the sadistic younger sister Miu is a series of humiliation every day! She lives in diapers 24 hours a day! That's why she can't go to the toilet and always wets herself! She is forced to eat baby food, put to sleep with picture books, and if she masturbates, she is spanked with love! But even if she eats or changes her clothes, she is spoiled and praised! If Miu's overflowing maternal love makes you melt, maybe you would like to become a baby too? ! For those of you who would like to try it at least once, we present you with 30 days of forced baby life!
