Well me and my sister started being fuck buddies two years ago but last year she started dating a guy she said she it migt be the real thing so we stopped having sex. It seems she was wrong about the guy, it was older that she 10 years and after fuck her good he dumped her after 9 months. It took a while for her to recover but now we are fucking again, and better than before. I guess the other guy tought her new things.
