It's been a while since I've had seen my uncle and his family. Last I remember they had 5 kids. 3 boys 2 girls. Two of the boys were older then I and the rest were some years younger. I had been known to be the bad one of the entire family. My mother had said that I was going to have to stay at her brothers house for the summer. Hoping that I would stay away from the city life. I was fine with that I need a break from the party seen. My mom dropped me off. Here you go. I sure hope you get something out of this I don't know what else I can do. All go mom. My uncle came out of the house. Let's set the ground rules. After hour of do's and don't he said that he was going to be gone for a month and I had this to look after. He gave my aunt a kiss by and said give the kid's one an I love them. I then started on chores splitting wood. It was hot out and I took my shirt off. That is when the kids come home from school. My aunt came out and said don't know if you remember this is Dawn. Kari. Dave. This is your cuz Steven. We said are his. Man they have grown. Yes Dawn just turned 18 last week. What no way yes my aunt said. She only looks 15 if that. Right she gets a hard time at school bully why. That's no cool. It will be nice for her to have some closer to her age her this summer. After a couple of days went on . I was finding my self looking a Dawn and thinking how turned on I am that she looks so young. I was out working in the yard when Dawn and one of her friends came over to lay out in the sun. Her friend was smoking hot. But I was more into Dawn. I took my shirt off to show my body. I was a 5'10 say 185 lb all rip muscle. Let her friend get wet looking at me hoping Dawn was to. I could here them talking and laughing. I started to work closer to here. And look at Dawn. God she was so hot looking. Wearing a bikini hot pink that showed how tan she was. I decided I wanted a close up and was about done for the day. When I got to them her friend got up and by Dawn my moms here. Her friend looks at me and says your fucking hot. I said thanks. Looking a Dawn's perfect smooth skin so fucking tight she gets up as I just look at her. What are you looking at as if she had something on her. She stood 4'9 and looked like she was about 80 lbs. Just enough tits to need a bra. And an ass that would fit in both of my hands one cheek per hand. My cock was starting to grow. Dawn walked way to go in the house I walked behind just to look at her ass in the bikini as it rode up in her cheeks showing the soft round ass. You like my friend don't you? You want to fuck her don't you? No she's not my type. Read she looked back at me with a glare. Her blond her the her side. What is your type. Well I I like blonds and hot. She went in. I wanted to add that look so hot and young like her. Next couple days. Dawn would flirt with me. Show me skin ass just enough of a tit here and there. And talk so much more. Fun like. She would even grab my muscles. I think she liked them. The very next day Monday. Mid day Dawn was messing with me. I said you best stop or I'm going to get you. She laughed did it again. I ran after her. Boy she was fast and fit. Got you she giggles. As I tickled her. I was touching her sides. And my cock was pressed against her cunt with clothes on. She moved around to where my cock was hard enough to I know she could feel it grow. Stop stop please. I did she got an ran. Oo shit what did I do fuck. The rest of the day she said not a thing. Even at supper. Well guys I think I'm going to go to my room. Which was in the basement. And watch a movie. Dawn says can I watch with you. I looked at her. If your mom doesn't mind. No go head. Just remember you need to get up early. OK I put my pajamas on. I went to my room it was more like a small apartment. I sat on the couch. Dawn did the same. We started watching. And in about a hour in Dawn started picking like last time. So I grabbed her to tickle and she right away jumps on top of me and sat on my cock.
