Over the next few days Allyson and I fucked like rabbits every chance we got. There was always the danger of getting caught, which only fuelled our passions. We had an especially close call one afternoon after work when Dad had left to get lumber and Mom was out with her friends.
Allyson had worn a black knee-length skirt and a black tank top. I had sat down to watch TV and she came in, showing off her new skirt. She asked, "Where's Dad?"
"He left to get some lumber," I told her.
My sister got that twinkle in her eye and before I knew what was happening she was kneeling on the couch beside me. She unbuckled and unzipped my pants, fished out my hardening prick, and proceeded to give me a vigorous sloppy blowjob. The wet sucking sounds filled the house.
I was in heaven as I watched my little sister's head bob in my lap, taking as much of my cock into her face as she could while stroking the rest with her little fist. It wasn't long before I felt the familiar tingling in my balls signal to me that I was approaching the point of no return. "I'm gonna come," I breathed.
Allyson didn't slow or falter in her work on my cock, bringing me to the brink and then pushing me over with all of her might.
At that moment the jangling at the lock told both of us that someone, either Mom or Dad, was about to open the back door and discover us.
Allyson registered the sound an instant before I did. She quickly lifted up, spun around, and sat on my lap. Within a second my cock slipped up between Allyson's firm thighs and her skirt draped my entire lap, covering up the fact that my pants were even unbuckled.
As Dad strode through the kitchen and into the living room, Allyson said, "But I don't see why they have to answer in the form of a question. Why don't they just ask a question and answer it like every other game show. I mean, what's the big deal?"
Dad paid us no attention as he walked past us and sat down in his chair.
For my part I pretended to watch the show, Jeopardy, on TV as I came. I tried to hold back my orgasm. I succeeded for a moment, but in reality I was too far gone and Allyson's thighs were too soft as they rubbed against my inflamed prick. Cum rushed up my shaft and blasted out of my cock.
Looking down, I watched each wad of cum cause Allyson's skirt to dent up in her lap. I pumped cream up and out of my dick, against her skirt, and down across her thighs again and again.
She glanced at me with a smile as she squeezed her thighs together tightly. She looked a little worried, a lot scared, and extremely turned on.
I took a ragged breath and said, "Well, that's what makes the show different, isn't it?" The cum coated my cock and her thighs, at first warm, and then, as it spread, it began to cool. I was in heaven after my orgasm but I tried not to let it show on my face.
As we sat there in silence and watched the show, my cock deflated and slipped from between her thighs. I could feel my pants getting wet and I was glad her skirt was black because I couldn't see any stain on them, though I knew her thighs were covered in my cream.
All Dad had to do was ask us to help him with something and we'd have been busted. Instead, during the next commercial, he went to his bathroom.
Allyson and I slipped out of the living room and into the two bathrooms on the other end of the house to clean up.
It was a close call and we resolved to be a bit more careful in the future. Problem was; we didn't stick to that vow. If we had, things might have turned out much differently.
***
Several days later, still a week away from the concert, Allyson gave Dad the money for the concert tickets. I was so proud of her, though I still felt a little guilty for her buying my ticket, but that was her gesture of thanks to me for providing the transportation.
Karen and her kids had been coming by to visit more and more frequently. At one point I thought she had caught a look between Allyson and me but she hadn't said anything. We were pretty good at hiding stuff from Mom and Dad, but Karen and her kids were more observant. We were trying to be even more careful around them.
Karen and I had spoken a few times over the weeks and during those talks I had noticed a change in her. I was attracted to her, always had been, but she had started wearing somewhat more provocative attire. She had always worn sundresses but one time, for example, she showed up wearing one that had a hemline well up her thigh and a neckline that showed off her big full breasts to great effect.
Despite myself, I grew hard in my jeans as we talked, imaging my cock sliding in and out of the valley between her big breasts or thinking about bending her over, flipping up that skirt, and slipping my dick inside of her cunt. I wondered how different she would feel from Allyson. Being older and having had twins I could only assume it would be looser around my dick.
She told me, again, how she wanted us to be closer. She spoke about our childhood and occasionally touched my arm as she spoke. I felt an overwhelming urge to kiss her.
When she stopped and waited for me to respond, I wanted to tell her that everything was fine, but, despite my growing physical attraction for her I could help but be honest. I said, "Look, I was twelve when you left home. I thought you were so cool and I was proud that you were my big sister, but you left."
Karen frowned. I didn't enjoy the fact that I had put it there. That look didn't suit her cute freckled face, though I had seen it on her quite a lot lately. She put her hand on mine and asked, "Is there no way we can get back to the way we were before?"
I wanted to say something reassuring but I couldn't. I said, "Geez, Karen, that was a lifetime ago."
"Well, then, can we start over? Maybe have a new type of relationship?" Karen insisted.
What was she suggesting? Surely she wasn't feeling as attracted to me as I was to her. Though Allyson had shared my attraction, I had no illusions that everyone wanted me. Still, what did she mean? I finally said, "Maybe."
