Snowed In update

Previously I wrote of me and my sister Michelle going our family cabin and getting snowed in and having sex. On returning home I made advances to Michele and she would sometimes let me fuck her again. Not all the time but enough to keep making advances towards her. Then Last winter I decided to go back to the cabin and asked Michele was she interested joining me. She was and we headed off for 2 weeks, we didn't get snowed in again. But we slept together every night while there. Michele says she likes our sexual adventures together and I said I do also. If nothing else happens we will go back to the cabin next winter.
