At dinner me and my cousin sat next to each other. She was acting a bit strange and I asked what was wrong. She said nothing was wrong. A few minutes later I felt a tickle on my leg. I didn't think much of it, until I felt it again. I rubbed my hand on my thigh to see if that would stop it. Turned out it was my cousin tickling my thigh. I said "What are you doing" She looked around and told me to shush. I felt her grab the button of my pants and she unbuttoned it. I was too afarid to say anything because I thought someone would hear. She unzipped my pants and reached in. She grabbed my dick and started stroking it slowly. I was in so much shock that it was actually happening, but I kind of liked it. I acted normal and continued to eat so no one would think something was strange. She eventually started stroking faster and harder. She whispered in my ear "Wanna put this inside me?" I thought about it for a second and nodded. She let go of my cock and I put it away very discretley. Thankfully no one noticed. I told my parents that me and her were going for a drive to meet up with some friends really quick and then we left. We drove up to nearby baseball field where no one was at during the time. And she unbuckled her seat belt and hopped on my lap and we began making out. I reclined the seat back and she started to unbutton her shirt. Her tits just fell right out and I instantly grabbed them and started sucking on them. She loved it so much. She pulled my pants down and my hard dick fell right out. She jumped over back into the passangers seat and she started to suck it. She knew what she was doing. After a few minutes I said "Wanna hop on" She replied quickly "Fuck yes" She pulled down her leggings and threw them in my face. She took her panties off and stretched them in her mouth and rubbed them in my face, As she was positioning her self onto me she said "If anyone were to find out about this, we'd be so fucked." I said, "Yeah we would be" She said, "Well I'm getting fucked either way" and winked. Then she slid my cock into her pussy. She rode me for a good 5 minutes. I opened the door and I carried her out of the car with her still on my cock. I put her down and I told her to lean against the hood. She leaned against it and I slapped her big ass. I stuck my cock in her again and she started moaning really loud. The dog across the street was barking it was so loud. I told her to be quiter and she said "I'm sorry it feels so fucking good" I continued to fuck her hard and fast. She started yelling "I'm cumming, Oh shit yes!" She pushed me away and she squirted all over the side of my car. I said, "Fuck whos gonna clean that up?" She grabbed her panties and wiped it all up and threw them back in the car. She said, "Keep going" So I did. She squirted again but luckily not on my car. I tried not to cum but couldnt help it, I pulled out but some got in her pussy. I came all over her back and ass. She reached around and started to get it with her fingers and licked it off. I said, "Fuck I think I came in you" She said, "Yeah you did, but it's okay." Not sure how it was ok, but shes not pregnant luckily, I asked her the other day. I drove both my cousins home that night (Their both sisters) and my other cousin grabbed something from under the drivers seat. It was my cousins panties. She said, "Hey aren't these yours?" My heart sank and my cousin said, "Um no. I do have a pair though." My other cousin said, "Bullshit these are yours." I could tell we were both nervous. My other cousin said, "Ah don't worry I won't tell anyone. You were horny and curious. I get it. So how was he?" My cousin said, "Really?" My other cousin said, "What I'm curious." She said, "Yes he was good." My other cousin said, "Hm maybe I should give it a try." I was kind of turned on by that. She texted me yesterday saying she wanted to meetup on saturday so I can assume thats what she wants. She said to meet at their house and that her sister was gonna be there too. So I'll post about that if it happens. I know it's wrong, but it's hard to turn down sex. Even if it is from family.
