Hi, I'm Beth and my uncle Sean are headed to the beach. We have my 10 year old cousin with us. I'm 13 and am tall for my age at 5-6. I have nice boobs like my mom. I am in nice shape with blonde shoulder length hair. My uncle is 22 and an average cute guy with brown hair to his shoulder too.

We got to the beach and picked our spot, put our blanket down and headed straight for the water. It was a hot day. We went to about waist deep water and sunk down to our necks in water. My cousin and I were hanging on my uncles shoulder as usual. She stayed in for about ten minutes and made her way to the sand to play. I stayed with my uncles as some waves started to roll in. He would bounce us over them and settle back to the bottom. I ended up straddling him on the last wave and thought nothing of it. The next set of waves rolled in and he jumped them again. this time I felt him get hard and was holding me against it. I could feel it pressed right between my lips longways only separated from our suits.

I asked him if he was hard and he said yes. he had a funny look on his face. He said you feel turned on too, don't ya? I said no and tried to pull away without making a scene. He held me firm and said c'mon you'll like it, just sit here a minute. He said look at your nipples, they're hard as a rock. I said because I'm cold and now scared. He then said ok, I'll get my niece Jessica. I said no, no, I'll stay. He smiled and started moving his legs around. He reached down and worked his penis out from the leg of his baggy swim shorts. I could feel it against my leg and vagina. He reached between my legs and pushed my suit from my vagina. He told me to hold it like that, so I did. I was so scared.

He told me to use my other hand to guide his penis in my own vagina. The only reason I did this was so he wouldn't get Jess. I grabbed his penis which was very big. I thought there was no way of it going in. I put it against my hole and he said not to scream, it may hurt. He pulled my ass to him and I felt him slide in. I said take it out, please take it out. He just pushed further and I felt my virginity pop. I started to tear up, I was no longer a virgin. He started rocking me up and down slowly. I felt him going deeper each time.

Jessica joined us and I told her to go back but she didn't listen. She said I wanna ride, not knowing my uncles dick was inside me. Every movement he grunted and I did too from the subsiding pain and the feeling that was supposed to feel good but was making me sick. Jessica started mocking our sounds which made it that much worse. I started thinking of my blood in the water and sharks, but we're in the gulf and never hear of sharks. He whispered in my ear of how tight and good I felt. He kept pumping in and out of me, I thought we were going at it forever. He grabbed my ass really tight and held me there against him. I could feel his whole penis throb inside me and then I felt his warm sperm fill me inside. He moaned and put his head into my neck. I wanted to cry as he kept pumping sperm inside me. He finally let me go and I slid off of him. I cleaned his sperm out of me as much as I could. We went back to the blanket and he rubbed sunscreen on me as if I was his prized trophy. He got me back in the water four more times that day by taking Jess for a swim and each time sliding his penis inside me.

He now uses me when we are at his house as a sex toy and at the beach when he gets us to go. I'll never get used to it.
