I was 25 and lived in the country with my parents and my niece was having trouble in the city so she moved out to the farm with us when she was 18. Mandy was a bigger girl and developed very quickly at a young age. By the time she was 15 she had D size breasts and a nice ass for a big girl. We had always been close and kind of always had each other in our sights but nothing ever happened between us. We were very close, she told me everything and along with the information about her past boyfriends she told me she was still a virgin. It was not unusual for us to cuddle up while watching movies but this time it got kind of weird but for some reason I went with it and it got very interesting. The day she turned 18 was the day I finally got to have what I had been wanting for years.

For Mandy’s 18 th birthday I took her out to dinner and we rented a few movies to watch afterwards. She was wearing a low cut top which showed off her cleavage and a pair of blue jeans which outlined her ass very nicely. All through dinner I kept finding myself staring at her cleavage and thinking about playing with her large breasts. The ride home was normal after dinner and when we got home we snuggled in for a movie. As we were lying on the bed with my arm around her she took my hand and placed it on her breast and started moving my thumb in circles around her nipple. This went on for about 10 minutes or so and as she let go of my thumb I continued rubbing her nipple and than I started lightly pitching it between my thumb and fore finger. I could tell she was really enjoying it because she was moaning and squirming around a little bit. I started playing with her other nipple with my other hand and she was really starting to get turned on. I did this to her for about 15 minutes and all of a sudden she reached down and started rubbing my cock. It felt so good as she played with my cock that I never even thought about stopping it. I slowly pulled up her shirt to expose her bare breasts to me and then I proceeded to lightly lick and suck her nipples and as I did this she reached up my shorts and started to jerk me off which felt so amazing. I then slid my hand down into her pajama bottoms and felt her nice warm juices flowing from her sweet young vagina. As I tweaked her clit between my fingers I could feel her squirming around and she was jerking me off faster and her grip on my cock got a little tighter. She started moaning very loudly and I had to cover her mouth so my parents could not here her. I could tell she was close to orgasm so I started rubbing her clit very quickly and as she was having her orgasm I started to finger her very quickly which made her first orgasm even stronger and intense. She stopped playing with my cock to recover from the crazy orgasm she had just experienced and as I slowly removed my fingers which were soaked with her juices she started stroking my cock very quickly. I made her taste her juices off my fingers and since I was about to cum I made her suck my cock and as I cam she got her first taste of cum and she swallowed the huge load I had just ejected into her sweet innocent mouth.

The following afternoon we kind of got talking about what had happened and decided it was best not to let it happen again but later that evening my parents went out and we had the house to ourselves and as I was watching television she walked into the living room in a black thong and frilly black bra and as soon as I looked at her I knew we were going to get into trouble once again. We had many encounters in the following 5 years until she moved out but this one was by far one of the best.
