My aunt is 32 and I am 19. Her name is Alison. She is extremely hot. She has short blonde hair. She has huge breasts and a big butt. She has the right amount of fat on her, making her a little chubby but not too much. She has the most beautiful face ever. Everyone thinks she is beautiful. She is married to my dad's brother (there's no blood relation). One day, I was at my grandparents while her and my uncle were there. My grandparents and my uncle went next door to the neighbors house. I said I would just stay at the house. Oddly my aunt said she would too. So I'm sitting on the couch on my phone, she sitting on the other side of the living room. She gets up and sits next to me, which I thought was odd. She leans over on me and straight up says, "I've always wanted to be alone with you." My heart started beating and I instantly got an erection. We talked about it for a couple minutes, then I kissed her. We started making out. She got on top of me and took her shirt off. I took my shirt off. A few seconds later and we're both in our underwear. She takes her bra off and I see her huge fits with perky nipples. I start to suck on them. I lay her on her back and take her panties off. She has a perfect pussy. I start licking it. I then take my underwear off and stick my dick inside of her. I felt and indescribable warmth. I had had sex with several other women but none felt like my aunt Alison. I think it was because what we were doing was so dirty. Also we knew my uncle and grandparents could come home at anytime. We passionately made love for about 15 minutes with her on her back. She eventually came. Her pussy tightened up around my cock and it was the best feeling ever. We made love on the couch for a few more minutes. I said, "I'm gonna cum!" She then said the best thing ever. "I'm on the pill. I want your cum!" I then came inside my aunt's tight pussy. I laid beside her for a few minutes then we got dressed. Maybe five minutes later, everybody else came home. My aunt and I are know involved in a hot affair. We've had sex about 10 times since then. Everytime I cum inside of her.
