Is the inside of the kotatsu extremely easy to guard? It was a heaven for panty shots! One day, it was getting cold, my sister brought a friend to our house. We all gathered at the kotatsu to do our homework, but I suddenly peered inside. You can watch as many up close as you can see the panty shots of my younger sister's friends! While pretending to be asleep, she was excited by her panty shot, and my sister's friend found out that she had an erection! Even though I thought he would get scolded, my friends seemed to be in heat and secretly touched my erect dick so that their younger sister wouldn't find out. What's more, they say things like, "Please touch me too"...!
