Five years ago a came from Cuba with my husband, after we settled down we told my husband's youngest sister to come and live with us. We were best friends during high school and had some great lesbian action during those days. I've told my husband that I had sex with his sister and he got really excited with the idea, now that she was with us it was time to do something about it. And we did. For some time it was only the three of us then she got a boyfriend and (for my luck) he join the fun too...
