My older sister Minami is extremely lazy. Other than going to work, she doesn't do anything at all. She does everything wrong. She's too lazy to even buy clothes, so she has exactly two changes of clothes all year round. . She looks so slovenly that no ghosts probably pay attention. After being single for five years, someone suddenly invited her out on a date. Her previous relationship didn't work out so she almost has no dating experience. She came to my room to ask if I could borrow a dating magazine to look through, but all she could think about was food!!! I had no choice but to advise her to go shopping for other clothes, she couldn't just dress like this and go meet people. The next day she came to my room again to show off the clothes she had just bought. The tight bodycon dress shows off her gorgeous figure. She kept posing and because her skirt was a bit short, I could clearly see her T-shaped panties peeking out!!! I almost lost my mind at her charm. When I woke up, I made love and ejaculated straight inside her without even realizing it. I thought she would tell my mother and I would die but no! Not only was she not angry with me, she also kept changing her outfits and asked me to rate them. She wanted me to help her practice sex so she could be more confident when going on dates. And from that day on, we secretly made love every time mom left the house, everything continued until the two of them started going out together...
