AMBI-143 Three days alone with my non-blood-related younger sister! I took the opportunity to get very intimate!! Konno Miina

My mother remarried, and I gained an older stepbrother who isn’t related to me by blood. At first, I worried whether we would get along, but we became so close that our relationship went beyond that of siblings. We usually spent time together in secret from our parents, and now our parents will be away from home for three days because of a family memorial service. I’m really looking forward to spending those three days alone with my stepbrother.
