I was finally beginning to realize how my step-sister really felt about me. When she said those three little words earlier, I wasn't sure what to think... but now she had just admitted that fucking her big brother was like a dream come true. And because my parents were away for the weekend, we had the opportunity to realize that dream again and again. In fact, we spent most of the weekend at home, with very little clothes on, and fucked at every opportunity.
But the amazing thing was... we not only had great sex, but we also talked a lot the entire weekend. Although we had practically grown up together, we never really seemed to communicate well before I left for college. The truth was, we didn't get along well at all... I always viewed Stacy as just a little brat and teased her mercilessly. And now she had grown into a beautiful young woman and I was actually getting to know her for the first time.
Among the things that I discovered... she was a virgin until she turned eighteen, when she started dating her ex-boyfriend, Jeremy. She actually had very little experience, although she confessed that she masturbated often (and even thought about me on occasion). She had only been with Jeremy a few times, but often gave him blowjobs and seemed to be an expert little cock-sucker. I also learned that my sister was on the pill... something that my mom had actually insisted on when she started high-school. I was very thankful to learn this last bit of information, as protection was not even a consideration the first time we were together. But my sister reassured me that "we were covered" as she put it.
My sister also learned a few new things about me... such as the fact that I had a regular girlfriend for most of my freshman year in college. We had met at a party and before you knew it, one thing had led to another and we went back to her place and fucked all night long. Afterwards, we dated off and on for most of the school year, but unfortunately we broke up just before I returned home for the summer. The truth was, our relationship was mostly physical... so I didn't miss her that much. "Still, she was great in bed," I told my sister with a wink. "I just wish..." I stopped myself.
"What?" my sister asked inquisitively.
"Nevermind. I don't want you to think I'm perverted." I told her.
"Jason, you are fucking your own sister..."
"Step-sister" I corrected her quickly and we both laughed.
"I promise. I don't think you are a pervert," she assured me.
"Well..." I started hesitantly. "The sex was great and she had an incredible body, including the tightest little ass. But she never was interested in trying anal sex."
"Oh really? My sister said and giggled. "So was her ass as sexy as mine?"
"Honestly? No. I think you have the nicest ass that I have ever seen, Stacy." I said, almost blushing.
My sister got quiet for a moment. "You know, I've never tried anal sex either," she confessed. "But that could be fun," she said and giggled again.
I looked at her in surprise. She smiled a wicked little smile at me and walked over to where I was sitting. Leaning forward, she kissed me and then whispered in my ear, "What do you think, big brother? Would you like to fuck your little sister in the ass?"
My cock grew hard instantly at her suggestion and she stared down at the bulge growing in my boxers. "I guess that I already got my answer, eh?" she said and winked. Having said that, she turned around and slowly slid her panties down over her cute little ass, teasing me a little. Her tight little pussy peaked out from between her legs and I could tell that she was already soaking wet. Crawling up on the bed, she looked back over her shoulder and blew me a kiss. "I'm waiting for you," she said.
Looking at my sister, on all fours with her ass in the air waiting to be fucked, I realized she was without a doubt the sexiest woman I had ever seen. I pushed my boxers down to the floor and quickly crawled up on the bed behind her and grabbed her hips.
"Are you sure about this?" I asked her.
"I've never been so sure of anything in my life," she told me. "You helped make a dream of mine come true this summer. Now I want to do the same for you."
