Note: I never thought that I'd actually write a story myself but after seeing the feedback my husband got writing about our adventures with the Bra Shop I took up his challenge to write a better one than him.
Jo and I had always been competitive since we first met at high school. First it was sport, then academics and then inevitably it was boys. We just had that competitive streak about us which meant that we would always try and out do the other.
Physically we had similar builds, long legs, slim waists and big tits. Mine were bigger (44FF) but only just so I won that competition although Jo had bigger nipples so we called it even when it came to who had the best chest.
During our final years at school our focus was solely on boys so the competition was often about who could sleep with the captain of the football team first or who had sex in the most outrageous place (I won that by screwing the captain of the swim team in the Principal's office).
After high school we went to university where we studied marketing and business. The competitions continued, who slept with the most guys at the same time, who had the most orgasms in the one night etc. The problem was the competitions were losing their appeal so we agreed that we needed something different, something that would really challenge us, but what was it going to be?
You see the problems with the other competitions was that they were often over very quickly so what we needed was something that we could compete for over a longer period of time which gave us each the chance to take the lead while still giving the other girl a chance to retake it. We both agreed to put our minds to it and come up with the best competition yet.
One night we went to the movies to see "Supersizeme" and it was while we were sitting at a bar afterwards that the thought came to me. Just like in the movie we going to supersize things only this time it was going be cocks not burgers. We were going to see who could find and fuck the guy with the biggest cock. Just like the movie we wanted to upsize our sex lives and our competitions. Jo was wrapped with the idea. I knew that she would be as she still went on about a guy she fucked two years ago who she said was hung like a donkey.
Now for this competition there needed to be some rules so we settled down and drew them up over some cocktails. This was going to be fun! The first thing was to define what 'biggest' actually meant. Was it length, circumference or a combination of both? We both agreed that fucking some pencil dick that was 10inches long could hardly claim to be the biggest likewise fucking a 5inch prick as round as a can of beer just wouldn't cut it either so we agreed it had to be a combination of these two vital statistics. That agreed we went about sorting out the finer details and set the finishing date for the competition. As we both liked the idea that the lead could change several times we set the end date as Valentines Day some four months away.
Now for the all important prize. Jo suggested that the winner would get the pleasure of fucking the biggest cock in front of the loser who would have to sit there and watch without being allowed to join in. I could only imagine what it would be like to take a massive cock while Jo watched on, she would be going crazy.
So with that done the Supersizeme competition was officially on. As we would be doing our own thing over the coming months we agreed to e-mail each other photos of our best efforts. Each time we fucked a guy with a bigger cock we would e-mail a photo to the other girl.
The next day I couldn't get the competition off my mind so I started searching the internet for big cocks to find out just how big some guys were. After 30 minutes of searching I was beside myself, some of the guys were huge, no make that massive. I had never seen cocks so big. I found myself with one hand down my panties playing with my pussy while scrolling through photos of the most massive guys imaginable with the other. Surely these photos weren't real were they?
As turned on as I was sitting there looking at these pictures there was a nagging thought in my mind, what if I couldn't take one of these huge fucksticks, after all the biggest cock I have ever had was only 7.5inches and while that was not a problem there is big difference between 7.5inches and 12inches! I needed to know if I could handle one of these big guys so that night I went to a nearby sex shop something I had never done before. WOW! What took me so long to do this? I couldn't believe the things they had. I tried to look calm and in control but my wide eyes and rock hard nipples protruding through my silk top probably said otherwise. The guy at the counter was flipping through some porno mag when I walked in but now he couldn't get his eyes off me. I guess its not every day that tall blonde with huge tits, tight ass and stilettos walks in.
After a few minutes he asked if he could be of any assistance. Feeling a little embarrassed I thought of running out but I knew that I had to go through with this if I was going to be any chance of beating Jo so I told him about the Supersizeme competition my girlfriend I are in.
