I have been working on the one for some time now and have divided the story into chapters. All participants are over eighteen years of age.
Chapter 1 -- The Apartment
I was starting my next to last year of high school (grade 12 here in Ontario) and was incredibly excited about it. I had just turned 19 on September 2 and had an two years of football eligibility left - I had missed the August 31 age limit cut off. I had had a great year last season on the gridiron and this season promised to be even better. I was a big kid -- the two inches I had grown this summer put me at 6'4" and my constant working out had filled out my 235 pound frame into a muscular one. Although shy, I was proud of my physique. And my new cock. Without a word of a lie, it was now well over 11" and it never ceased to amaze me just how long and thick it got when it set it's mind to it. Although still a virgin, I had fantasies about a blossoming sex life yet to come in my new apartment. The testosterone was definitely flowing.
My parents had allowed me to set up my own studio apartment in the basement as an 18th birthday gift and it was just finished last spring. A separate side door entrance allowed me to come and go pretty much as I pleased. As long as I checked in with them on a regular basis and ate supper with them upstairs periodically, they left me to my own devices. The best feature of the apartment was the expensive corner steam shower unit I had convinced them I needed. With a four foot radius, the curved sliding door gave me plenty of room for a partner to join me. Not what my parents had envisioned I'm sure, but one that I lived in hope of fulfilling.
As a studio apartment, it was really just one large room with only the toilet and sink behind a closed door. The king-sized bed shared the space with both the shower, kitchenette and the stairs descending from the side door landing. A table and chairs served for both eating and studying and a loveseat rounded out the furnishings. A chest of drawers and a dresser substituted for closets. I had also scored a heavy duty second hand massage table that I left set up under the stairs, easy enough to pull out when needed. I was a big guy but the apartment was roomy.
It was apparent early on that the living space offered no privacy for changing. This was, of course, only a problem when I had guests over, but I remained optimistic. A last minute addition had been a bi-fold, three panel screen on wheels that I had found at a second hand store. The three panels consisted of fully framed two-way mirrors that were reflective from the one side and transparent from the other. It was a sturdy setup and could be wheeled out of the corner into place easily and stood at just under five feet in height and six feet wide. It was meant to offer a modicum of modesty in an apartment with no walls.
With three panels and it's five foot height, it did a poor job of actually screening me when I needed to change. The panels could be angled to allow a two or three-sided reflection, but any background light made them transparent from the reverse side. I hadn't realized it when I purchased it, but the bright light above the dresser served the purpose admirably. With it on, I might as well have been disrobing in front of a pane of glass for anyone watching from the room.
I was developing into an exhibitionist before I knew what an exhibitionist was. In three years of school, I had grown from 5'9" and 145 lbs. to 6'4" and 235 (Canada hadn't gone metric yet). Everything seemed to be growing along with my physique : my football prowess, my self admiration, my burgeoning fantasy life and my cock. I was so proud of myself that I imagined that everyone else felt the same way too.
We lived close to the school so my parents got used to seeing my football teammates and our friends coming and going during the season. They reasonably set "visiting hours" from 8 AM to 9 PM during the season which was meant to ensure that I got to bed at a reasonable time. Our coach was adamant that we avoid having girlfriends during the season as they were a source of distraction and sapped our strength. Although we all grumbled about it, I was secretly relieved because I was really too shy to court. I was a virgin and was desperate to hide the fact.
Chapter 2 -- The Audience
I first realized that I had acquired an audience at the apartment the Saturday morning before school started. Labour Day weekend. There was a small sliding window above the sink in the apartment which was always open during warm weather. It was the only source of natural light in the kitchen and offered an unobstructed view of the entire apartment interior from our backyard.
