I am now 21, then 16. During that time my sister Ema was 14. We were really close like any other brothers and sisters. She was giftted with a look that could bring about lust to any man she inteended, and she was the hottest girl around the neighbourhood and her school. But she avoided the boys, despite hundres of proposals. She was a good friend, to my girl friend whoes name I need not mention, but back then was 15, and was in the same school as her, although unlike my sister was a school skipper. Me and my GF were dating for a while and we were ok with each others family. But one day, I spotted her with another guy and attempted to bash him. But she stopped me and told he his her new BF and she could still be with her, if I would allow her to have multiple BFs. I told her that there was no more need of her to talk to me anymore, and I waill make a much better GF. I returned home that evening, and found myself alone. Mom and Dad were at work, and my sis didnt return home yet from her swimming practice. Nobody, not even her own brother could take his eyes of her when she was in her swim suit. 5 minutes later the door bell rang, and it was Ema. Whats more she was still on her swim suit, looking sexier than ever. As I stood still not being able to take my eyes off her, she 0grabbed me into a hug and started crying saying that she heard about my break up with my GF, expressing her shock. She tried to let go, but I didnt. She tried harder, but no use. I just couldnt let go, I wanted to hold on to her forever. After a lot of efforts she finally brokefree and asked why I wasnt letting her go. I finally confessed that I loved her and more than anything else in the world, wanted to f*** her. She started crying and ran into her room, shutting the door. I started knocking the door, not knowing it wasnt locked, telling her I was sorry and saying that I would never say something like that ever again. After a while, she told me to come in, and I got the shock of my life seeing her on the bed, FULLY NUDE! Before I could fly into her like a cannon ball, she told me to nudify myself, which I did, and as I got on top of her, she told me that she always had such feelings for me. We went at it for about four hours, the bed was all wet. The day that was supposed to be one of the worst in my life, turned out to be one of the best in my life. Dad returned really late that night, and mom decided not to return at all, as she was staying with her mom, my grandmom as she was a little ill. From then on me and my sis continued to have sex, atleast once a week. Now we live far away, and I have a new GF, while she has a new BF. We last fucked each other about two and half years back. I really miss her company, both as a sister and a partner. I dont know how Ema feels about in now, but Ema was the best partner I ever had.
