I'll show you mine, if you show me yours. - Chapter One
I was too young to remember when my mother and father divorced, vaguely even remembering when she remarried, and upon doing so, suddenly inheriting an older sister. And perhaps it was because I was so young at the time that I didn't really mind it either. I now had someone to play with, especially as Kristine, though she later went by Kris, was quite the Tom Boy while growing up.
Needless to say, we grew close, we'd always been affectionate with one another, sometimes to the point where her father, my mother would caution us about getting "too" friendly with one another at times. Though usually, that was all that was ever said, just periodic precautionary warnings that never really led anywhere. As for Kris and I, we'd behave for a while, and then slowly allow our playful, innocent attractions reestablish themselves. Eventually, our parents gave up trying to separate us emotionally, especially as we'd never given them a real reason for concern. At the time, sex just wasn't an issue for either one of us. Maybe we were too young, or maybe we'd simply not considered the possibility of that as we happened to live in the same house together or something. But we were close. Perhaps closer than a real brother and sister would have been.
And not to say I didn't occasionally get on Kris's nerves, or she mine. We did. Just like any real siblings might have. We had our moments. Especially when Kris began bringing home her friends, one of which I had an immediate crush on. But with Susan being a year older, dating a Jock and being a very popular cheerleader herself, just like Kris was, it wasn't something I could possibly hope to pursue personally. All I could do was worship her from afar, and let it go at that. Which is why Kris would very often chase me away from hanging around all the time. Something she didn't normally do whenever it was just the two of us.
By now of course, sex was very much an issue with me. Far more curious than experienced, I had stumbled a handful of times into catching Kris either partially undressed, or fully nude twice. Only one of those of which she had never known I'd actually stood there watching her without her being aware of it. All the rest had been those quick fleeting, or surprised glimpses causing a moment of panic, awkwardness, though even then a bit of playful teasing coming from it afterwards.
Obviously Kris had developed nicely, which I hadn't up until that particular moment thought too much about. Funny how circumstance can change all that.
When we'd grown up, one of the household rules was, we did our own laundry. Something I didn't at all mind as by then I'd not only been having numerous "wet dreams", but I went through hankies like they were going out of style. I had a stash of girlie magazines tucked under my mattress, easily accessible for my daily pleasures for one thing, but even those didn't arouse me nearly as much as seeing Susan whenever she came over for a visit with Kris.
It was a typical Saturday morning. My stepfather had gone off for his weekly golf outing with the guys much earlier. My mother very often went off to visit with friends for their weekly coffee gossip session for a few hours, leaving Kris and I home alone where it was expected we would perform and do whatever chores we had before heading out for the day.
Saturday was my day to sleep in, which I normally always did as Kris was an early riser, always had been. The beauty of that was, she got her wash going first thing, and then afterwards I'd begin my own so we never really got in one another's way.
For whatever reason, I simply couldn't sleep any more. I had actually gone to bed early on Friday, but it was obvious I had gotten more than enough sleep as I lay there wide awake, finally deciding to get up. As Kris slept downstairs much closer to the laundry room, I figured she would already be up and about doing her laundry already. I gathered what little I had, which included stripping the sheets off my bed, and decided to carry them downstairs, pile them on the floor until she was finished, and then begin my own.
Opening the door to the basement, I could already hear the washer as well as the dryer going. I made my way down the short flight of steps, bundle in my arms being careful not to trip as I did so as it was somewhat difficult to see. I guess because of that, I was a bit quieter than usual coming down. Reaching the landing of the hallway, I turned looking towards the laundry room and saw the door was partially closed, though not entirely. I began making my way towards it when I stopped cold. I had seen movement for one thing, so I knew Kris was inside the room. But what had caught my attention was the fact that she was entirely naked! It was again just a brief quick fleeting observation as she passed by the semi-open door. Obviously she'd been sorting out her laundry in the nude, for whatever reason, though even this I found a little odd. Curious, I deposited my bundle on the floor, and then quietly crept down the hallway towards the laundry room. With the door ajar the way it was, I stood next to the wall, peering through the hinged side of the door, which allowed about an inch or two of observation for me. Kris was standing at the sink looking at herself in the mirror. I found myself holding my breath as she reached up, cupping her own breasts and simply stood there holding them while looking at herself.
Kris had great looking tits. And though I had seen them very briefly before, I had never had the pleasure of doing so for any considerable length of time like I was doing now.
I guess it wasn't all that odd that she would stand there and look at herself. I'd very often done that much myself, examining and looking at the changes in my body while growing up. And that on some few occasions, had led me into doing other things as I stood there, curious about my own body no differently than anyone else might have been, and probably were. Though again I had never considered that aspect as being something that Kris herself very likely did too. But there she was, standing there examining her breasts, which I suddenly found quite interesting, not to mention a little arousing and exciting as she continued fondling herself. I was of course cautious and careful in my observations. Should Kris discover me standing there looking at her, I knew there would be hell to pay, not from my parents, as that's something she'd never have squealed on me for doing. But from her directly.
When she suddenly began rolling her nipples between her fingers however, that's when things got really interesting. This was something entirely different than just catching her getting dressed, or coming out of the bath. This...was something naughty.
Kris certainly didn't have overly large sized breasts, but they weren't small either. I guess they were perfectly proportionate for her 5'9" frame an inch taller than I was myself at the time. She normally wore her long brunet colored hair in a ponytail most of the time too, but at the moment, it hung loose and full down to the middle of her back as she stood there. And because it did, it likewise directed my continuing gaze downwards, her cute, tight firm ass more revealed at the moment than I'd honestly seen it before. Standing with her back towards me, I couldn't see anything else of course as the counter top prevented anything else from being revealed, aside from her nice full breasts. Each of which was capped by a dollar sized dark tan nipple that I now realized had puckered, grown taut and erect as my step-sister stood there fingering them observantly.
By now I had obviously become erect, which wasn't all that good of a condition for me to be in, as I was wearing nothing more than a pair of tighty-whites at the time. It wasn't all that unusual for either one of us to run around the house in our underwear, especially as our parents very often did the same. Seeing mom in nothing more than a bra, panties, or a slip had never been a big deal. Nor was it when dad came down in nothing more than his boxer shorts, a robe which was usually open as he sat reading the paper over a morning cup of coffee. Even Kris had occasionally darted about in nothing more than her bra and panties, though she was usually always in a hurry when doing so.
But like I said, this was entirely different. Especially with me now standing there with a hard on, which I had absentmindedly began fondling as I stood there looking through the crack in the door.
