SDMF-031 I feel calm when I bury my face in my sister’s mako, so I do it every morning. Pink Family VOL.33 Mai Hanagari

A brother and sister who live with their mother. My brother supported my sister’s life by working part-time as a day laborer. There was a secret that such brothers and sisters could not tell anyone. When my brother came home from work and was feeling weak, he would bury his face in his sister’s skirt and do cunnilingus. It had become a habit. Gradually, the act escalates and finally comes to have sex.
