Cumming home
After my second deployment to Iraq, I went home for a couple of weeks of leave. I was a 24 year old single, male Marine, who hadn't seen my family since I completed AIT, prior to my first deployment 4 years earlier. When I got home, my parents had about 12 of my old friends waiting to greet me at our house, along with my younger sister and my grandparents. It was nice to see everyone, and it was a great party, but I was really glad when the party broke up, as I really needed to kick back and unwind for a while. My grandparents were sleeping in my old bedroom so my parents had me rack out on the floor in my sister's bedroom. She had just turned 18 and was getting ready to go off to college in a few months. After my parents went to bed, me and my sis sat on her bed and talked for a while, catching up on lost time. I learned that she still didn't have a boyfriend, which was surprising, because she had grown into a very beautiful young lady. After a while, I told her I needed to get some sleep, and she helped me roll out a sleeping bag next to her bed. She asked if I minded sleeping on the floor and I said it was fine. I went into her bathroom to wash up before going to sleep. As I was brushing my teeth, she came in to the bathroom. "I'm sorry, bro" she said, "but I really have to pee bad". I was amazed as she walked over to the toilet and dropped her drawers and squated on the can right in front of me. She let out a slight moan of relief as I heard the urine splashing into the toilet bowl. "You don't mind, do you?" she asked. "After all, we are siblings, it's not like your gonna get turned on watching me pee, are you?" "uh, not really" I replied. I had my back to her and could clearly see her shaved pussy in the mirror in front of me, as she pissed with her legs spread wide. I was glad I was turned away from her, because my cock was rock hard and was nearly ripping the crotch out of my skivies. I watched in the mirror as she wiped the pee from her pussy lips and stood up, then she turned around and bent over to flush the toilet. She had truely the finest looking, firm, round butt I had ever seen in my life. She turned around and our eyes met in the mirror for a moment and then she smiled at me with a look that no man should ever see from his own sister. She walked up behind me and wrapped her arms around me and gave me the biggest hug ever. "I really missed you big bro" she said. Then she reached down and grabbed my hard cock through my under shorts. She still was naked from the waste down and I could feel her warm pussy rubbing against my ass. Her perky breasts and erect nipples were poking me in the back through her T-shirt. I had an overwhelming desire to throw her on the floor and fuck the living shit out of her, but this was my sister. My little sister. I knew it was wrong and I didn't know what to do. I just stood there paralyzed, but then she grabbed my hand and led me to her bed. I followed, like a lost, puppy dog. She gently pushed me back onto her bed and pulled my shorts off. "I've been dreaming of this night for years, brother. I have fantasized about you popping my cherry for years, and now it's gonna happen." I was silent, not knowing what to say. She crawled between my legs and took my cock into her mouth and sucked it like a lolly pop. I grabbed her legs and pulled her around into the sixty-nine position and started eating her pussy. It was the wettest, sweetest pussy I had ever tasted. After a few minutes I was on the verge of blowing my load in my sisters mouth, so I stopped eating her out and told her to stop. "I want your sweet pussy on my cock, sis." I told her. She rolled over and lay on her back, legs spread wide, beckoning me to enter her forbidden hole. As I climbed on top of my sister, she grabbed my throbbing cock and gently guided it into her tight vagina, slowly, inch by inch, until my balls were nestled up against her taint. She came after a dozen or so slow, deep strokes. When I felt her pussy convulsing on my cock, I shot the biggest load of my life inside of her. Needless to say, my sleeping bag didn't get used for the entire two weeks I was home. Can't say the same about my sister's pussy, though.
It trips me out seeing all of these stories where everyone is no younger than 18, like no one thinks of sex or at least will do anything until they are 18.
I had to force my sis and warn her not to tell
