Maybe fact or fiction, we will never know.
It had been a long three weeks, I had abstained from any form of sexual involvement, I wanted to see how long I could last without exploding. I had a flat mate at the time, so the general house rule was that if any doors were closed, it meant that private time was underway, as we are both straight, to which we both adhered to and followed by the rules, but other than that we could go into the bathroom if either one of us was in the shower or bath, to chat or take a leak or whatever.
So after the second week of my own no touching rule, things started getting tough, I was walking around with a hard on for most of the day, struggling to focus, and found I had pre-cum in most of my shorts. By the time the third week had arrived, I couldn't take it anymore, I had to have a wank, and it had to be NOW!!, so off I went to the shower, shut the door behind me, and jumped in, things started off slow, I was as hard as a rock and my cock was throbing with excitement, I started really having a good jerk off when in walked my flat mate, we both just stood there, me with cock in hand, and he looked like a deer caught in the headlights of a fast moving car. I was shocked when the words, 'carry on' were uttered from his mouth, he then proceeded to take off his shorts, and stand out side of the shower door jerking off to the sight of me jerking off. I couldn't last long, I came in loads, all over the shower door, the floor, and all over myself, he was disappointed that I had finished so soon, but alas, I was not done, I had three weeks of build up inside of me, I got out of the shower, and both of us stood there butt naked, having a toss, he stopped me, he grabbed my hand and put it on his cock, and he put his hand on mine, and stroked it up and down, this went on for about an hour, I couldn't take it anymore, I was about to explode again, he told me to wait for him, he caught up and we both came at the same time, we shot hot creamy jizz all over each other.
We practised the same wanking session a few more times in the months that followed, then the lease was up and we parted ways.
Aah, the good old days.
