I am a 49yo guy and I am fucking my petite little 20 yo niece. She came to visit one day and we got wasted on bourbon and cocaine, she told me that she has just started shaving her pussy and I told her that I also shave. She giggled and said I'll show you mine if you show me yours, she pulled down her panties and there was her lovely bald pussy and then she said your turn. I took off my pants and and my cock was there in full view, she then came over and grabbed it and lifted it up to have a look at my shaved balls. My cock reacted by going hard and she looked at me and said look uncle's all excited . To my surprise she started stroking my dick asking if it felt good. I reached down and began to rub her pussy. It wasn't long we went into the bedroom and sixty nines each other. We sucked and fucked each other all through the night and in the morning both felt a bit guilty and said this must never happen again and no one must find out. We did the same the next week and the week after that. We are now fucking each other 2 or 3 times per week and it's great. We know it's wrong and it can't last forever but we both enjoy fucking each other so much who knows when it will end.
