BF-711 While my girlfriend was away visiting her hometown, I was seduced by her older sister for four days. Riho Matsumoto

On the day she came back home, her sister came over. When I told her she wasn't home, she asked me to be her boyfriend just for today, and made me go shopping with her. Her body was pressed against mine, and she even got close enough to kiss me. If I accepted her like this, everything would start. But when she tempted me with those big boobs… I couldn't hold back anymore.
