My sister Hailey and I were real close growing up. We are only a year apart (she is older) Our parents worked a lot, so we had lots of time to ourselves. We would often play games which most of them were made up. The event told here happened when I was 18 and Hailey was 19.

One afternoon, I was home from school and Hailey had just walked in from work. The cable bill had not been payed and was shut off for that day. Bored out of our minds, we thought it would be fun to play one of our games we use to play when we were younger. Now I must admit that at that point I was a virgin. My sister -believe it or not- was too...sort of. She was a hypochondriac and didn't want to take the chances of getting pregnant, so she had anal sex instead. She was broken in though. Her boyfriends had fingered her quite often. Anyway, the game we played was called "Guess What". The idea is that we would put on a blindfold and had to guess the random object the other chose. Three guesses and if you don't get it on the third you lose. You were allowed 3 hints. One of those hints could be physical (you could touch the object), which we called the physical challenge (not original...I know).

We started to play. We were quite good at this. After several successful go rounds, my sister decided to get a little creative. It was none my turn to guess. I couldn't get the first two guesses, so I used my physical challenge for the third. Hailey placed my hand on the object. I instantly knew what it was. But it couldn't be...this was my sister. Embarrasses to give the real answer, I blurted out that it was the carpet. It was the carpet alright, just not the floor. My hand was right on top of my sisters hairy pussy! I froze. What was I to do? My sister made the move for me and started to rub my hand on her natural pussy. I was freaking out, but turned on at the same time.

Next, my sister took her shirt and bra off to reveal the nicest tits I have ever seen. Hailey looked right at me and told me to suck on her nipples. Hey, I was in deep already so why not. I complied. I wrapped my lips around those pink perky nipples on her c cup breasts. She smelled great. I was beginning to forget about any worries I had about groping my sister. In fact I nearly forgot she was my sister. At this point, she has my hand rapidly rubbing her clit. She's really getting into it as I furiously suck on her tits. She is stating to get close to cumming. Not satisfied with just one my one hand, she grabs the other and puts two of my fingers inside of her. This drives her over the edge. I can feel her pussy contracting, not to mention her hand that is crushing mine that was rubbing her clit. Next thing I know she screams in my ears that she's cuming, and then squeezes a little harder and then loosens her grip. I pull out my fingers and they are soaking wet. My sister had cum. I made my sister cum...I MADE MY SISTER CUM!?! What just happened? Am I dreaming? The smell emanating from my fingers from my sisters cum is quite desireable. I wanted to taste her, but that would be enough for me.

I slowly got up and started to walk towards my bedroom. As I was about to turn the corner to go down the hallway to my room, I hear Hailey say to me, "Where do you think you're going? We're not done yet." She walks up to me and starts unbuttoning my pants and then pulling down my underwear. What did I just get myself into...
