Phase 2: Conversion
The electrician returned to work on monday feeling relaxed and strangely refreshed after a crazed weekend of fucking with a guy he met at the bar on saturday. He was still feeling randy, and his suddenly - and delightfully - enlarged cock stayed semi-hard as he admired the muscled bodies of his construction-worker coworkers as they began the day's work.
It was hot inside the incomplete new office building, a hot summer day with no air conditioning installed yet, and many of the men worked shirtless, sweat glistening on their skin. Quickly the whole place smelled of sweaty men, and the air was thick with the moisture of sweat... and nanobots. It seemed like just another workday on the surface, and no one noticed the men occasionally shifting around to adjust themselves to more comfortably position their cocks, which seemed for some reason to feel nice and tingly, despite that their underwear seemed strangely tight.
An few hours later the electrician and a flooring installer both happened to head to the first floor mens room, which had already been completed, at almost the same time. The electrician arrived to find the room empty, and sighed with relief as he made his way to a urinal and whipped out his massive cock to give himself some relief from the increasingly insistent sexual urge caused by his new sex drive. As he was starting to stroke it good and hard, with his eyes closed and his head thrown back, the flooring installer walked in.
Seeing a shirtless man jerking off at a urinal would normally have repulsed the flooring installer, but he found himself strangely drawn to the huge, throbbing cock the electrician was stroking... and the electrician opened his eyes and looked around suddenly when he abruptly felt the flooring installer's tongue on the head of his big hard cock.
An hour later at noon the contractor finally noticed half the crew seemed to be missing but figured they probably went to lunch, so he invited a couple of guys to join him to go grab a bite at the sandwich shop next door. On their way out of the building someone needed to hit the mens room, and the contractor thought it would be a good idea anyway, and the other guys followed.
They walked into the mens room to find a full blown orgy going on... discarded clothes strewn about the floor, and eight or ten huge-dicked guys fucking and sucking frantically near the sinks. Stunned, he opened his mouth to shout his outrage at them but... wow, the sheet rock guy's arms looked really... attractive... and the carpenter's chest looked really hot as he piston fucked the electrician... and so the contractor and his buddies found themselves adding their clothes to the pile on the floor and wandering into the enticing action.
In the middle of the group of thrusting bodies, the electrician was in bliss from the nine inch cock pummeling his prostate. He'd already cum five or six times in the mouth of the tile guy sucking his cock, after having fucked the flooring installer wildly... but the semen kept building back up in him and his cock's time to get hard again was under a minute, so the pleasure was too intense for him to stop. He sucked passionately at the ten inch cock being rammed into his throat and moaned with pleasure as he felt another warm load of cum being deposited in his ass, and it pushed him over the edge into his eigth orgasm of the morning.
The contractor, meanwhile, was feeling horrified at what he was doing but couldn't seem to stop himself from giving in to the overpowering urge to fuck the sheet rock guy. As if in a trance he shoved his cock into the guy's eagerly offered ass and shot his load almost at once as he felt the hot soft tightness of a man's ass on his cock for the first time... but before he could bring himself under control he found himself getting hard again and starting to thrust in and out and fuck the ass hard. He knew this was disgusting, this was immoral, he had to stop it, he... God, it had never been this good with his wife. Why had he never thought of this before? He felt a cock begin to press itself into his ass and realized not much work was going to get done on the building that afternoon.
Across New York these scenes played out as men who had been modified by the nanobots returned to work. The nanobots spread out to do their work on their coworkers, turning everyone quite firmly homosexual, enhancing everyone's sex drive to make them have a hard time controlling their raging libidos, slowly starting to break down everyone's weight problems, and giving all the men really big cocks. However, it wasn't just coworkers. Every nanobot carrier who took the subway to work spread nanobots to everyone they had brushed past in the station, and exhaled more on everyone near them in the train car. These people in turn passed on the nanobots to their coworkers, people they brushed against on the streets, everyone in the restaurants they had lunch at... it was spreading like wildfire.
In Amsterdam the couple who had gone on vacation had spread the nanobots through the air to everyone on the plane, and all those people spread the nanobots throughout the country. The couple also made wild use of the city's gay sex spots, spreading more to men who then went home from their own vacations, spreading nanobots throughout the world. Within days, it was spreading everywhere.
Symptoms of the nanobot induced changes started showing up in the news within a day or two. There was a temporary dip in productivity, which economic analysts didn't yet know enough to attribute to vast numbers of people having wild gay sex while they learned to keep their new libido under control long enough to get a day's work done.
Psychologists and psychiatrists experienced a sudden influx of new patients seeking counseling about their sudden newfound homosexuality and huge sexual appetites. Of course the doctors got the nanobots from the first patient to sit there for an hour's session and breathe at them, leaving the poor doctors hard pressed to control their desires for their patients.
Within a week the divorce rate skyrocketed from formerly heterosexual couples who had suddenly lost interest in each other, or had caught each other cheating with coworkers and friends of their own genders. This finally brought it to the public's attentiont that something big was going on, that it wasn't just them who was suddenly and inexplicably desperate for gay sex. The news finally broke about definite symptoms... for women, a loss of interest in men and an uptake in desire to be with other women, and for men, tingling feelings in the "privates" followed almost immediately by unexpected growth of "the male member", conversion to exclusive homosexuality, and enormous sex drive.
Public panic ensued as it became clear that the "disease" was spread by simple physical contact or even by air exhaled by a carrier. A run on filter masks at the hardware store only spread it further as of course sooner or later someone who already had the nanobots would pass through the store and unknowingly leave some behind.
As a few men turned up who seemed unaffected by the nanobots despite everyone around them being converted, it became apparent that the "gay-inducing-disease", or "GID" as it was rapidly becoming known, required body fat when all of the "immune" men were skinny as a rake. When word got out fundamentalist christians everywhere went on crash diets, not knowing it was too late if they weren't already absurdly lean. A few of the "immune", perhaps from frustration with their spouse having already converted and lost interest in them, or perhaps from jealousy at the frequent wild sex their acquaintences were obviously enjoying or the enormous cocks their friends had grown, decided "if you can't beat 'em, join 'em" and started overeating. They began to convert in days, although it took them slightly longer than for others to grow in their new and improved private parts.
Fat people turned out to spread GID abnormally strongly to everyone around them... since, of course, the nanobots had more raw materials to work with. The fat people in question were more delighted by their rapid weight loss, and of course they were getting plenty of exercise through suddenly frequent sex.
Men who had already converted found themselves enjoying extra large meals to give their body the energy they needed for the frequent fucking, and the raw materials to make all the extra semen. But, thanks to the GID nanobots, they continued slimming away any fat.
Sales of home video products dropped sharply. Sales of lubricants and condoms rose sharply, as most of the modified men had not yet realized either that they were immune to sexually transmitted diseases or that their asses were now self-lubricating. Sex clubs were doing business like they had never imagined. In the evenings secluded spots in parks filled up with horny men eager to pull off their clothes for hours and hours of frantic fucking... many finding themselves unable to find their clothes in the mess afterward and strolling home nude, usually with a playmate or two. Police initially didn't know whether to try to arrest everyone for public indecency or to give in to reality and accept that there were too many to cope with, but it soon became apparent that when police tried mass arrests the arrested men would only end up fucking like animals in the holding cells, and soon enough the very cops who had arrested them would give up and let them free so they could join in the fun.
Mostly it was only the men who had already been modified by the nanobots who started to notice that they seemed quite able to do without sleep for days and would still feel relaxed and refreshed every morning if they spent the whole night having sex, and they were a bit too busy having fun to concern themselves with notifying the press.
In his loft in Brooklyn, the engineer finished reading the latest news report about his creation. The network had had to get a temporary evening news anchorperson after the previous one had gotten the nanobots and become a bit too involved with the weather man to continue reporting for a few days. Scientists hadn't figured out that it was nanobots, not a disease, causing GID, but it would probably happen in a few days after doctors stopped fucking long enough to look in the electron microscope for a while. He wasn't concerned. Phase 2 was going splendidly, and soon almost everyone on earth would be converted to homosexuality. The changes were permanent: even in the unlikely event doctors and scientists came up with a way to eliminate the nanobots from someone's body, they structural changes the nanobots had made to the anatomy and brain structures of their carrier could not be reversed, and anyway the person would almost immediately pick up more nanobots. No, soon the whole world would be gay, he thought as he turned off the computer screen and turned to leave his office to return to the orgy in his living room.
As he opened a couple bottles of poppers and placed them on an end table he thought happily of what would be coming soon in Phase 3, only a few weeks away. He left several bottles open on the table to spread their fumes through the room, and took another with him to play with as he wandered into the group and his huge new cock once again grew hard. As he felt a hot wet mouth slide onto it and a rock hard cock probing at his ass, he put the bottle to his nose and snorted in a deep hit. As he felt his blood start to throb in his head, and a pleasant feeling of pressure set in on his mind, he felt happy as he surrendered himself to another night of mindless fucking.
Phase 3 was coming, and the world had no way to stop it.
