... of course it didn't just happen at night, having sex with my mother. We would also fuck once I got home from school. Since my sister had a tutor for band, that meant I would be alone with mom till Dad came home. That gave mom time to fuck me, and she did, over and over again.
Years have passed since when me and my sister had incest sex. She went into therapy after our encounter, not telling mom and dad what had happened. It was now like she erased the entire incident from her memory. I suppose if you cross a line and fuck your own brother, maybe that is a way to get over it.
Now I'm ready to go to college and mom sends me and my sister off together and alone to investigate. Here I thought dang can I somehow pull off another chance to fuck my sister? I know she knows, no therapy hides a hard dick... a hard dick for my own sister.
