My older sister Minami is extremely lazy, besides going to work, she doesn't do anything else, always blaming others for everything, even too lazy to go buy clothes so she only has two outfits to wear all year. She looks so unkempt that probably no one notices her. After being single for five years, suddenly someone asked her out on a date. Her previous relationships didn't go well, so she has almost no dating experience. She came to my room asking to borrow a dating magazine to look through, but she only thought about food!!! I had to advise her to go buy different clothes, she can't meet people dressed like this. The next day she came back to my room to show off the new clothes she bought. The tight-fitting dress perfectly accentuated her beautiful figure. She kept posing, and because the dress was a bit short, I could clearly see her T-string underwear!!! I was almost losing my mind to her seductive look. When I came to my senses, we had sex and I ejaculated inside her without her noticing. I thought she would tell our mother and I would be in big trouble, but no! Not only did she not get mad at me, she kept changing into different outfits and asking for my opinion. She wanted me to help her practice sex to feel more confident on dates. And from that day on, we secretly had sex every time our mother left the house, things continued until the two of them started dating each other...
