[IPIT-010] I’m sorry, but… you’re so delicious I can’t help it.

A secret sex movie of Kanna Shiraishi, Arisu Nanase. Today is the first day I went to my girlfriend’s house to play. She lives with an older sister, but today she was absent because she had to go on a business trip. While I was chatting with my girlfriend, she suddenly came back. It turned out that due to a mistake on the partner’s side, the business trip was canceled. I don’t know if it was by accident or on purpose, but she brought her beautiful, round butt in front of me when my girlfriend went to make tea. That night, the image of her perfect butt kept appearing in my head, making it impossible for me to sleep. I wanted to have sex but my girlfriend wouldn’t let me, so I was thinking of going to the bathroom to relieve myself when I suddenly heard a moan coming from somewhere. Following the moan, I saw that Arisu’s room was open, and looking inside, I found out that she was masturbating! I officially got to admire her beautiful, big butt! While I was engrossed in watching, she also discovered me. But instead of getting angry, she pulled me into the room, allowed me to kiss her and make love to her! Unlike my girlfriend, she let me make love to her whenever I wanted. And from then on, we continued to secretly make love while I still maintained my relationship with my girlfriend…
