SSIS-083 The older sister was lewd and tempted to fuck her younger sister's boyfriend

Meiko and I have been together for two months, our relationship is extremely platonic. Today Meiko's parents went on a trip so it was just her and her sister Riri at home. She immediately invited me to her house to visit and it seemed like this was the breakthrough for our relationship. As soon as I got home, I saw her sister. My first impression of her was that she was very beautiful, elegant and innocent. But during dinner that night, when my girlfriend went to the bathroom, she immediately came close to me, whispered lustful words into my ear and then suddenly kissed me! The sweetness of her tongue, the scent of her body, plus her lewd words made my penis uncontrollably erect! Seeing that I looked uncomfortable, she immediately helped me solve the problem and soothed my boy. And from there, our secret relationship began, we secretly made love to each other even when my girlfriend was around!!!
