My sister

It started when we were younger.I was living in a camper on our parents land. My sister Lesa and I was always the black sheep of the family. Lesa is two years older blond hair big tits she was hot. I was high naked jerking off to porn when there was a knock at the door. I was expecting a chick to stop by so me and my big hard on answered the door opening it stepping out on to the porch but to my surprise it was my sister. I hopped back in the camper saying "I was expecting someone else come in I'm gonna put some clothes on". Sis said "dont get dressed on my account". As I got dressed I remember when I stepped out on the porch I saw my sisters eyes locked on to my cock and a grin crossed her face, thinking that was weird and her comment. She needed a place to crash for a day or two. I gave her a blanket and went back to bed to finish jerking off. I was going at it good when I heard sis asking what I was doing. I said watching a porn and she asked to watch with me. I covered my cock telling her to come in. She asked if I still sleep naked and I said yes and she said she still did too. Sis get under the sheet and removes her shirt I knew she was naked under the sheet. As the movie went on sis tells me I don't have to hide jerking off if i didn't mind her doing the same, I said it dont bother. We were both masterbating at one point she kicks the sheet off on to the floor. She didn't stop I didn't too. The movie ended she asked if she could watch me to finish. We looked at each other and masturbated. She finished first but I was high and it takes a long time to cum. Sis said if i get her high that she would help me cum. She got high then put on her panties and then told me to stand up and then pulled her panties below her pussy. She stepped up until our body's were touching and my cock went between her legs and up snug against her slit but not in her. She put my hands on her ass and her arms around my neck. She told me to act like I was fucking her. I started humping her and she dirty talked me. It didn't take long I was ready to cum and she took my cock and put the head in her pussy making me cum a bucket of cum. Sis pulled up her panties to hold my cum in her.
