This happened a few years ago (2010) but thought I'd share. I have a half sister that I didn't meet until I was 24. I first had contact with through facebook, and when we first started chatting I was stationed overseas and she was also overseas because of a relationship she was in at the time. We chatted through facebook here and there and eventually skyped one day. I'm a decent looking guy and she is above average looking. I remembered getting off of skype and thinking to myself, "was she flirting with me? Nah.. no way." She's a little younger than I am by a few years, at the time I was about 24 and she was probably 21. Let me add that she has a great body, very toned, tanned, black hair, and the most beautiful big blue eyes. Very beautiful indeed.
So, as time went by we really didn't chat very much at all until a random set of events changed all of that. It just so happens that she moved back to the states and was very near where I would be residing on my two weeks of leave. One thing lead to another, and she ended up coming to my place to pick me up so we could meet, and hopefully go out and party a little. I'm pretty sure my jaw dropped when she finally got to my location to pick me up. She got out of the car, ran over to me, and I instinctively picked her up as she jumped up on me to hug me. It all happened so fast but I didn't realize she had on very loose, very short shorts. My right hand went under her shorts and ended up cupping her left butt cheek. A little foreshadowing for the crazy night ahead, little did I know at the time.
Fast forward - right after she picked me up we're riding in the car and I'm trying to decipher wtf is going on at this point. We made small talk and eventually decided to go to the local casino since I'd actually never been before. We got there, started playing and kind of went separate ways for a while. The whole time we were drinking jack and cokes, left and right it seemed. All of a sudden while I was playing my game she came up and plopped a stool next to my game on the right side of me. She was extremely close to me, and while I registered her proximity, I didn't actually think anything would come of it. At some point as we were chatting we ended up making more and more eye contact, which resulted in us making out. And that action broke the seal on the craziest, hottest three days of sex I've ever had.
As we were walking out of the casino we were walking with our arms interlinked - I was pretty well wasted but coherent and able to walk under my own power without too much problem. We ended up going just a stones throw away from the casino to the levee where we decided to hang out. We ended up sitting on the crest of the levee, at the very top. She straddled me, facing me and I'm serious when I say we couldn't stop making out. We probably made out for what seemed like an hour and to this day it's the longest, hottest make out session I've ever had. Over time I got braver and so did she. She ended up raising her shirt up to let me suck on her nipples, which to my delighted surprise were pierced. It was probably about 11pm at this point, so there are people here and there walking by but not very many at all. She had a much better view of people coming than I did. Remember those loose shorts I talked about in the beginning of the story? This is where those come into play. As we were getting up to leave she bent over with her hands on the seat part of a bench. I smacked her ass a few times, then realized I could access her pussy due to how loose the shorts were. I started rubbing her pussy and she pretty much was like an animal in heat. I actually fucked her through the leg of her shorts, kind of unbelievable but it worked just fine. I ended up fucking her for a couple of minutes, right there, where anyone could see us. I didn't cum, but we ended up getting a hotel room right after that and finished what we started. Several times. I can still remember the sight of cumming in my step sister's mouth with those big beautiful eyes looking up at me. She was eager for my cum, never letting a drop go to waste. She offered her ass to me but for what ever reason it never ended up happening, which I regret. All in all it's still crazy, but I'd do it all over again in a second.
The story is 100 percent true!
