Suddenly voice changed, it seemed a very horny voice. I thought she possibly started fingering her pussy, this thinking made me to start stroking my d...ck. We were talking usual matters, but from my side whenever I was talking, I was relating it to praise her body, her beauty. I could not keep track as I was stroking my dick, neither she, sometimes she was breathing heavily. We did not talk directly sex. But it was sex I know. Its peculiar, its different, its enjoyable. When ever due to stronger. Jackie took care of that when our daughter Suzanne was born next.Beth had patiently waited her turn and promptly delivered twins, dubbed Mathilda and Madison. They were almost as pretty as their mother.Sharon followed next with Sonia, another cutie and then Rhonda with Pepin, another pretty girl like her mommy.Finally, it was Angeni's turn. Her labor had been more prolonged and she was exhausted by the time our twin sons Chatan (Hawk) and Chayton (Falcon) came into the world. Both were. But again it is when someone else is fucking me. But I try my best to get them to fill my pussy with their cum." As she told me all of that, she was stroking my dick and it was starting to get harder. My attitude towards her changed quite a bit from the thoughts I was having about us when I drifted off to sleep just a few hours earlier. Obviously, there was no future for us. She interrupted my thoughts when she said, "So will you fuck me once more before you go?" My dick was plenty hard so I. But how could my long legged perky titted sister be my brother?She must have seen my confusion. “I have male pseudohermaphroditism.”That didn’t help. “I don’t know what that means.”She had stopped crying and explained obviously quoting the doctor. “It means genetically I have an XY chromosome like you so I am male. But due to a genetic defect my body didn’t respond to the testosterone that would make me look male.”Talk about needing time to process! If my mom wasn’t acting so weird and Pat.
