Well, I'm 45, male, and my wife and I don't have sex any more. Her sis died, and her 12 yo niece came to live with us. After two months, she started setting in my lap, and flurting with me. One night, late on a weekend, we were not wearing much, warm night, and I got hard. She turned her face around, and said I think someone wants to have a good time. I said yes, but we can't. Kristen asked why not, and I said you are my wifes niece. She then said, yes, but she is asleep. I looked over, and sure enough, she was right. Kristen got up, slipped off her nitie and panties, and took hold of the bottom of my shorts, said pick up you butt and slipped them off me. Now we are both naked, and she gets back on my lap, and starts wiggling. I could not take it any more, so I picked up that little 12yo, laided her down on the floor, and ate her out. Her moans woke up my wife, and she said looks like you two need some privicy. She left the room, went to bed, and after finishing eating out her niece, I then fucked her, taking her viriginty. That was 5 years ago, and I still fuck Kristen, and my wife knows it, and sometimes watches.
