Filling my s****r - Sex Stories

Filling my s****r

... the park at around one p.m., it was a Sunday, so there was maybe one other couple there, so we had the whole place to ourselves. My Mom and Jim were drinking wine and playing cards together, so my s****r and I went to go swim by an area of the lake that had a tree swing. Katie was in a two piece swimming suit and was looking absolutely stunning. I remember watching Jim watch Katie, knowing that he was checking her out. So Katie and I swung from the rope swing a few time and were swimming together as the sun slowly began to set. We were really having a good time, and were being completely non sexual. We were both in standing level of the lake using each other as balance to avoid going under, when the first spark of sexual tension between us happened. We were neck up in the water holding each other when we practically bumped heads. On a whim I kissed her on the lips. She then looked at me with this serious expression and kissed me back. It was my turn again and I kissed her, only this time I put my tongue in her mouth. We made out for a few minutes and kind of scanned around as we did so to make sure no one was looking. Then through the water I pulled at my s****r's bikini bottoms. I found her pussy hole and looked at her in the eye as I inserted my index finger. She looked back at me and sort of bit her bottom lip. We were about arms length away from each other, so it didn't look as though we were touching. I put my other hand on her waist for positioning, and began to finger ...

This went on for about ten full minutes before Katie looked at me and said, "Lets go somewhere else." in a kind of hushed voice. So we got out of the water, me with a huge boner poking out of my swim suit. We went over by a big Weeping Willow tree and hid between it and two bushes. We began frantically French kissing while equally jerking each other off. Finally I kind of push Katie back and pull her swim suit bottoms off. She stepped out of them and stood in front of me naked from the bottom down. I dropped to my knees and pushed her back against the tree. I then spread her legs and began to eat her pussy right there in the open. She kept grabbing my head and stuffing my face and tongue deeper into her cunt. I pulled her down and pushed her legs apart and immediately stuck my cock in her. We fucked with her sitting down with her back against the tree. b*****r and s****r. We were matching each other's rhythms and fucking like pros. Eventually I began to get exhausted from fucking her in such an awkward position, so I pulled out and stood up to try to think of a better place. As I stood up my cock was now right in front of her face. She grabbed both my dick and my balls at once, pulled me to her, and began sucking my dick with her legs wrapped around my feet. It didn't take long for me to take control, and instead of her sucking me off, I was fucking her face. I remember the sounds of her ...
