I had just finished college and I was about to move and start a new job. My parents urged me to pay a visit home before I left for my new career. I did as they asked and I arrived to find my sister home. Jennie was now nineteen and she had grown up. She was no longer the flat chested girl I once knew. My sister had filled out. She now had big breasts and I had to admire them. Jennie said she knew of a lake were we could go swimming, about an hour from our home. I figured it couldn't hurt to get caught up with my sister.
The next day we drove to this lake. It was secluded and we seemed to be the only people there that day. We gathered up our belongings and walked down to the beach. My sister shed the shawl she was wearing and I got to see Jennie in her small bikini. We set our beach gear down and we went into the water. We swam a few minutes and then we walked back to our possessions. Jennie's bikini was clinging to her body. I could clearly see camel toe pushing through her bikini bottom.
"You know I really missed you these past years," my sister told me.
I told her I missed her as well. We had to be standing just a few feet from each other. My cock was stirring in my trunks as I looked over my sister. I could see my sister was gazing at my bulge. I don't know what came over me. I walked over to my sister and I took her in my arms. To my surprise Jennie didn't fight me. We were soon kissing each other passionately. I reached around and unsnapped Jennie's bikini top. Her tits came spilling out.
I had to see all of her. I reached down and pulled her bikini bottom off as well. It was just as I thought. My sister was shaved down completely. I shed my trunks and there we stood naked before each other. I led Jennie over to our beach blankets and I made her lie down. I knelt in between her thighs and I started to kiss her firm breasts.
"Oh my God Jeff," my sister cried out.
I sucked on each of her nipples and I was fingering her damp pussy. I just couldn't control myself anymore. I lifted my sister's legs up and I guided my hard prick to her opening. My sister gave me this look of passion and I entered her tight hole. Jennie let out this cry as I slowly fed her my dick. I pushed in until I was buried completely and I let Jennie feel my erect member. My sister's pussy was going into convulsions. I couldn't delay anymore.
I started to stroke my sister's wet quim with all I had. It was so quiet out there at the lake. All you could hear was skin hitting skin as I fucked my sister as deeply as was possible. Jennie told me to release her legs and she wrapped them around my back. Jennie squeezed me hard as I fed her every inch of my hard bone. I know how crazy it all sounds. There I was fucking my sister raw. I didn't even know if she was on birth control or not.
