IENE-842 My little sister is sleeping in the kotatsu wearing her school uniform and looking unguarded. Her panties are damp, making me excited! I can't hold back anymore, so I quietly commit incest without anyone around noticing!

The younger sister, a female school student, is carelessly exposing her panties in the kotatsu. Her brother gets extremely excited! When his sister dozes off, he crawls into the kotatsu and plays with her hot, damp area. He becomes engrossed when suddenly his sister wakes up. Thinking he might get scolded, but instead she touches his dick with her foot and provokes him. The brother gets turned on as well and they have sex right there! Suppressing their voices so no one around finds out, he thoroughly ejaculates inside her while she enjoys it.
