Because I had to take a short-term summer course for four days, I decided to stay at my sister's house. My brothers and sisters welcomed me very warmly, but my brother-in-law did not know a secret. That's me and you used to fuck each other! The thing is that before Suzume got married, because she was my sister, she always made me fuck her. I hadn't seen her for a long time, and I could see her lustful gaze when I looked at the position of my crotch. And sure enough, when my brother-in-law was away, she immediately rushed over and touched my cock. I kept pushing her hand away and ran away. But the truth is, I still miss her body, her big soft round tits, the times when I get my cock inside her wet pussy. Just thinking about it, my cock was standing up, and I was about to masturbate when Suzume opened the door and walked in. This time it was inevitable, she immediately let me look at her breasts, constantly saying lewd words in my ear to help me feel better. And during these four days, as long as my brother-in-law was absent, she would come again to fuck my cock, let me fuck her breasts, even fuck her pussy.
