Mark was an average guy, married but not all that happy, mostly because the fun had gone out of the marriage, at least for him. The sex had slowed to a trickle over the years, but being a committed man, he didn't seek opportunities with other women, he instead started watching porn and keeping himself satisfied with masturbation. When things slowed down in the bedroom, which seem to happen more often lately, he'd find time to log on to his computer and search through a few porn sites until he found something that excited him. This went on for a few years. I t wasn't ideal as far as his marriage went, but it did make the life more livable.
One evening, while the wife was off with some of her friends for a girl's night out, he logged on and began surfing. He was in need of a little relief and soon had viewed several porn sites but nothing seemed to really get his attention. In one of his searches he found and entry that simply stated, "Do not watch this video". Intrigued he of course clicked on the link and a video began playing on the screen. The video started showing various women, semi-nude and nude. Still curious he continued to watch. There was something in the background, a hum of some sort and occasionally the screen would flicker. At first he thought it was a computer glitch, but the hum became a little more pronounced and the flickering increased.
As he continued to watch, he felt his excitement rising and his dick getting hard. This confused him a little since the images he was seeing were just normal women in various stages of dress, nothing really explicit or out of the ordinary. Still his dick was responding to it so he continued to watch. The flickering was still increasing in frequency, and from time to time he could just make out something in the back ground. Occasionally, he caught enough to see what looked like an erection with something else in the background.
As he watched, he began unconsciously stroking his now hardening cock. The flickers started becoming more pronounced and he could definitely make out the hard cock in the fore ground, but not what was in the back ground. He noticed that the video was fairly long and even though he'd been watching for some time now, the video was only a short way into it's full length. He guessed that the flickering was a progression of some sort and if he continued to watch he would eventually see the whole image, so he forged on. What bothered him was his physical reaction to the video. His cock was as hard as it had ever been and he was really enjoying stroking it.
He continued to watch, checking the clock, he'd been at this for about 15 minutes. The flickering was now almost continuous now. He could clearly see the hard dick, nice size from the look of it, but he still couldn't make out the back ground images. They were obviously of people in some sort of sex act but the images were still fuzzy. He had stopped stroking himself because he was getting close to cumming and he wasn't yet ready to stop watching this video, but his cock was throbbing and the feel of it pulsing on its own was amazing.
He was so preoccupied with watching the video he hadn't really noticed that the hum had gotten louder. When he did notice it, he thought he could hear voices in the hum. Somebody was saying something but he couldn't quite make it out. As he considered the audio, the screen flickering suddenly changed. The flickering had become the main image and the nude women were showing up less and less. The image sharpened and the hard cock was now clear and on the screen most of the time. The scene behind the cock was still fuzzy, but he could definitely make out two people fucking.
Before the back ground cleared enough to make out the two people fucking, words started appearing on the screen. They would flash on and off quickly. He could make them out but they were never on for more than a second or two. Word's like, "You know you want it", "It's all you can think about", "Keep watching", and "You can't help yourself." Then all of a sudden, a message would showed at the bottom of the screen. It would change every few seconds, but would stay on just long enough to read it. The messages would say things like, "You find yourself drawn to it", "You find yourself getting excited by it" , and "Thinking about it makes you feel good".
