First off, I am a guy. I’m 17 years old. I’m 6’0, brown hair, and in good shape. I’m an only child except for my step sister who only visits a couple times a month. Her name is Kate and she is 16 years old. My mom married her dad when we were both about the age of 8 or 9 years old.

As a family, we stayed at a friend’s home in South Carolina last month for a week on vacation. The house was big with a bar and a game room inside. There was a large, private in ground pool outside with no windows on the pool side of the house. The pool and hot tub were connected and made for a very romantic setting.

The first day we got to the vacation home, we immediately unpacked from the drive from Rhode Island, and we were all pretty exhausted afterword, so we decided to walk to the beach nearby and spend the remaining of the day there. This would mark the start of the best vacation I have ever had. When we got to the beach, Kate and I ran to the ocean while our parents stayed back to set up chairs and an umbrella. We were swimming for a while and decided to get out of the water for a little bit and make something in the sand, but when we got out of the water, my sister full left, perfect 36C breast was completely out of her tiny little bikini top. I was shocked and just stared at her for a second, with my cock instantly growing. Kate then realized what had just happened and quickly re-adjusted her bikini top, but from this point on, I could not get the image of my step sister’s bare, naked breast out of my head.

Later that night, we were all back in the beach house and watching movies. I kept looking over at Kate and replaying the image of her fully exposed breast when she was walking out of the ocean. I couldn’t take it and I went to my bedroom’s bathroom to masturbate. When I got there, I pulled down my pants, put the cool lotion in my hand and began to think about Kate, imagining what she looks like completely nude. She was all grown up now and had big 36C tits, a round ass and good stomach. I was imagining her on her knees in front of me, topless, sucking my dick, and looking up at me, stroking my cock every time she went down on my dick. At last I came, and decided to go to bed.

The next morning I woke up, I went downstairs and saw Kate outside of the door swimming already and instantly, the image of the day before was in my mind. I decided to go out and join her. We were jumping in the pool and swimming around for a while and then she decided she wanted to see who could hold their breath the longest under water. I didn’t think anything of it until I held myself under the water and looked at her body through the goggles I was wearing. My mind was instantly taken off of holding my breath when I was staring at her huge tits and little pussy through her tiny bikini. My dick became so hard and I was nervous she would see it because she is my step sister, and I would be killed if our parents found out I thought of her like this.

Later that night, my prayers were answered when my mom told me her and Dan (my step dad) were going out for the night and might not be back in until late that night. When they left, Kate and I went to a restraint to eat and we came directly back to the house. I asked her if she wanted to go to the beach but she insisted on staying at the house and just relaxing in the hot tub for the night. I had no objections to this at all. When I came outside to the pool, it was already dark out and the hot tub and pool had been lit up in changing colors. Kate was in the hot tub when I jumped in the pool. After swimming around for a little while, Kate asked me to join her in the hot tub. I got out of the pool and into the hot tub but I was very nervous. Kate was looking so sexy and my cock was raging again. I thought there was no way Kate thought of me in a sexual way at all until she told me that she would give me a massage if I massaged her first. I got behind her and she sat facing away from me. I began to rub her back and massage her shoulders and neck, and then she reached back and untied her bikini string, letting her top dangle by the string around her neck. My cock grew ever harder now and was sticking straight up. She had to feel it on her back but she didn’t say anything so I kept massaging. I was hornier than ever now and I became more daring now too. When I was massaging her back I moved my hands to her sides and slowly around to the front of her body. My heart was pounding as my hands softly touched the skin right under my step sister’s tits. She still had not said anything; she just let out soft sounds of heavy breathing so I lifted my hands slowly up and cupped my sister’s big tits. Kate’s breasts felt better than I could have ever imagined; they were so big and the feeling of her hard nipples in my hands almost made me cum there in the hot tub.

As I was massaging her tits, Kate lifted up her butt and I felt her hands go down to her bikini bottoms as she slid them down and off of her feet. She had now given me permission to feel my own step sister’s pussy. I kept my left hand massaging her tits and slowly moved my right hand down her body until my middle finger was on her clit. I began to rub gently as she laid her head back on to my left shoulder and softly groaned in my ear. After a few seconds she whispered to me that she was going to turn around. She lifter her body off of mine, and turned hers toward me. Before sitting in my lap, Kate pulled down my shorts and I was now too completely naked in the hot tub with her. She then sat down on my lap. I could feel the front of her pussy rubbing against the bottom of my hard cock. She had her arms around my neck and I began to squeeze and suck on her nipples. When she got hornier, she leaned back, putting her weight on her arms behind her. I then put my hands on each of her thighs, and began to rub my thumbs in small circles while getting slowly closer to her vagina. When my thumbs touched, I entered my right thumb in her pussy as she moaned with her eyes shut. I pulled my thumb back and pushed it back in. She began to move her hips with my thumb, and I began to rub her clit with my fingers while pushing my thumb in and out of her. Kate’s pussy was so tight and warm. She was loving every second of this as much as I was and when she got more into it, she moved her butt close to my body again and her ass cheeks were now rubbing against my cock every time she moved her hips into my thumb. I felt like I was going to cum and she must have known and she stopped for a second.

We both sat there, my thumb still inside of her and things were quit until she asked me if I was having fun. I said “yes” and she pulled my thumb out of her pussy. She then moved closer to me and lifted herself above my cock. With her right hand behind her, she grabbed my dick and pressed it against her pussy lips. Slowly, she lowered herself onto my throbbing cock. It took her a three times to get all the way down on my eight inch dick. But her pussy was tighter than any girl I’ve ever fucked. She began to move faster now, up and down on my cock. She had her arms around my neck, her head laid back and her huge tits bouncing in front of my face. My step sister was fucking me better than any girl had ever known. Kate was lowering her pussy all the way down, taking all of my cock and moving her pussy back and forth every couple of minutes and she would start bouncing up and down again.

After about fifteen minutes of fucking Kate, I felt like I was getting close to cuming and I told her I was about to but she started fucking me harder. Her tits were bouncing and she was moaning loud now. She said to me, “I want you to cum, cum for me baby. You like fucking this pussy? It’s so tight on this big fucking cock huh? Cum for me.” As she said this to me, she was sitting all the way down on my cock, and I felt my dick get so thick, and I exploded inside of her, my cock pulsating every second and shooting more and more cum in her. She moaned even more now and she was moving her hips slowly, taking all my cum in her pussy. After I finished cuming, Kate lifted herself off of my cock and sat beside me. We sat there heavily breathing for a moment and she told me that I was her third but by far the best. That she’s never fucked without a condom before but not to worry because she was on the pill. Then she said that our parents can never ever find out. We both laughed and got out of the hot tub and went inside. The rest of the vacation, we were fucking each other every chance we could get. I’m just waiting for the next weekend she comes to visit her dad now.

If this is a true story then and the last story was a true story,then how did you feel and see her tits for the first time twice? I usually don't say anything but, come on dude, really if your going to lie at least have your stories in an order, don't do something for the first time twice.
