GG-287 Older sister's real sex education Azusa Itagaki

Azusa lives with her father and younger brother Ma-kun. One day, Ma-kun's friend came to visit with the notice of class observation that Ma-kun had thrown away. That night, when I asked Ma-kun directly about his situation, it seemed like he was feeling desperate because he didn't have a mother around and felt inferior. Azusa was worried about Ma-kun and decided to take off her clothes for her cute little brother.
