[PPPD-944] The older sister relied on her big breasts to seduce and steal the boyfriend of her flat-chested younger sister

A secret sex movie of Karen Yuzuriha. Today was the first time I went to my girlfriend’s house. That night, we were making love when her sister suddenly opened the door and saw us making love. I was so embarrassed that I wanted to go over and apologize to her. As soon as I got to the door, I was able to admire her beautiful, huge breasts while she was changing! The next morning, when my girlfriend went to put on makeup and change clothes, she kept using her big, round breasts to seduce me, causing my little guy to quickly swell up. Even though she really liked her girlfriend, her sister was too seductive! “You can have sex with me without a condom”, “You can ejaculate a lot of sperm inside me”. She kept seducing me with things that I couldn’t do with my girlfriend. The thrill of secretly shooting sperm into my girlfriend’s sister’s pussy made me extremely excited. When my girlfriend suddenly came home and found out, I still couldn’t stop making love to her. In the end, I cum all over her pussy right in front of my girlfriend!
