We had been having an affair for almost a year. The sex was incredible, more kinky than I had ever experienced. One evening we were planning a weekend at a motel near our town, and the idea came to us of having a masturbation marathon. The rules were simple: absolutely no contact at all; we would stay in the room from Friday evening until Sunday evening; we would remain together at all times - even going to the toilet (as children say, whether No. 1 or No.2); food would come from pizza delivery, etc. (this was not a very fancy motel, so no room service) but we arrived with over a case of wine; we would masturbate virtually continuously - all tools (porno videos, butt plugs, dildos were allowed and encouraged.
Although we would not touch one another, each person could ask the other to do something to stimulate the other. I often asked her to bend over and spread her ass cheeks so that I could see her asshole.
So, for forty eight hours we would do nothing but masturbate, eat and sleep (a little).
Friday night was incredible. Even striving not to cum, I blew my load four times in eight hours. I watched her take a shit for the first time - a surprisingly intimate (and strangely exciting moment). We jacked and jilled till we fell asleep from exhaustion.
On Saturday, around noon, the most amazing thing happened. We became bored. Seeing her big, beautiful tits wiggle always got me hard, but for the first time I was tired of sex - at least solo sex. And after coming seven times in less than twenty four hours, I had no desire to fuck this fabulous woman. And, she had no desire to feel my dick in her pussy.
The experiment was the biggest mistake we ever made. We decided not to see each for a couple of weeks. Luckily, when we did, we still had passion for each other. So to all you readers out there - even jerking off can be too much of a good thing.
