[SSIS-083] Going to girlfriend house to have a meal, unexpectedly being molested by girlfriend’s sister

A sneaky sex movie of Riri Nanatsumori with her sister’s boyfriend, Me and Meiko have known each other for two months, our relationship is very pure. Meiko’s parents went on a trip today, so it was just her and her sister Riri at home, and she invited me to her house to play and it seemed like a breakthrough for our relationship. As soon as I got home, I met her sister. My first impression of her was that she was very beautiful, virtuous, and innocent. But during dinner that night, when my girlfriend went to the bathroom, she immediately approached me, whispered lewd words in my ear, and then she suddenly kissed me! The sweetness of the tip of the tongue, the scent of her body, and her lewd words made my penis stand up uncontrollably! Seeing that I seemed uncomfortable, she immediately helped me to solve and soothe the little boy for me. And from there, our secret relationship began, we secretly made love to each other even when my girlfriend was around!!!
