Enlargement: Phase 3
The President of the United states denounced the sudden "trend" of homosexuality as "immoral" and proclaimed people with GID as "perverts", railing against them in nightly televised speeches and calling for them to be quarantined in remote camps... until it was leaked that during his thursday evening speech from the oval office, he had a male intern hidden under his desk sucking him off. After that political statements on the subject grew quiet for a time as the world considered the implications of what was happening.
Children seemed unaffected by GID until they reached puberty. In grammar schools life went on much as usual, but when a boy reached puberty, within a day or two he would quite abruptly grow an enlarged cock and an out-of-control sex drive. High schools had to begin to re-evaluate their curriculum as every school day seemed to drift into the pattern of all the boys disappearing from classes after a few hours to engage in frantic, animal sex in the rest rooms or locker rooms. Universities seemed to fare slightly better as the students usually had a couple hours to nip off and fuck each other between classes, although homework was rather suffering.
Phase 3 began about a month after Phase 1 was in full swing, by which time a large majority of the human population of Earth had undergone Phase 1 conversion to homosexuality and male genital enhancement. The changes weren't so fast this time... in many average people the GID nanobots had used quite a bit of the person's fat reserves as raw material to build many more nanobots to spread the changes through the population, so there wasn't as much raw material available for new changes this time.
At first men who had lost weight just noticed that over a week or two their skin started to tone up so they no longer had that slightly-flabby look of someone who had recently lost 5 or 10 pounds. But, in the weeks after that they started to gain a bit of muscle. Most guys initially dismissed it as the muscle they'd always had starting to show better... some thought it was just from all the exercise they'd been getting from sex... but within a month of Phase 3 starting all the Converted guys were starting to show powerful-looking arms and defined six-pack chests, as well as muscular everything-else. Not everyone was the same... some built up faster than others because they were eating enough to generate body fat to fuel the nanobots, but also the men were really filling out to a natural potential, rather than an arbitrary level of muscle defined by the Engineer. So, while men were all becoming attractively muscular, there was still a lot of natural variation, from tall lean guys to barrel chested muscle bears to slim wiry types. Some guys reached their maximum potential right away, while others kept growing...
The computer programmer fumbled with the keys to his apartment in his eagerness to get the door open and drag in the two hunks he'd met on the street on the way home from the office. Getting fucked by the guy from HR in the conference room during lunch and an impromptu afternoon quickie sex break in the mens room had been hot, but these guys were something else. They'd clearly just met as well when he came across them and were just starting to discuss where to go fuck when they laid eyes on him and called out to invite him to play. He lived closest.
They'd managed to control themselves just long enough to get inside and shut the door before starting to pull their clothes off of each other. The tall black haired hunk had shoulders as wide as an axe handle, a body like the letter V, arms that hung like a gorilla because there was so much muscle in his pecs they didn't allow him to put his arms quite to his sides, a thick carpet of soft black fur across his upper chest, and a real thick twelve incher tool that was starting to harden as he undressed. Meanwhile blond boy was his polar opposite, slim and boyish at 5'2 and 110 pounds of nothing but bone and wiry muscle, he looked like a skinny but well defined 12 year old even though his college ID showed him to be 19. (Black hair guy had been concerned.) His ten inch cock jutted out massively in contrast to his slim frame, already hard when he unleashed it from his strained shorts. The programmer was a good halfway between the two... lanky but with definition from his GID-induced muscles, a strong face, a soft sprinkling of light brown hair on his chest leading to his happy trail, big powerful arms, and an extra thick ten inch cock coming to attention for the other guys.
Blond boy slipped his arms around the programmer and began to hump against his body and cock even before they'd gotten out of the front hall. The programmer grabbed him under the arms and picked him up, allowing blond boy to wrap his legs around the programmer and hump away even as he was being carried into the bedroom. Placing him on the bed the programmer climbed on top, to find himself covered by black, already guiding his thick veiny cock to programmer's waiting hole.
Programmer felt so good as he was being entered. He felt so complete and fulfilled to have a huge cock buried in him, he'd never felt this good when he'd been straight. He also loved the feeling of a big man covering him as he now felt black's massive furry chest pressed to his back. His own cock felt really good with blond boy's leg rubbing in his crotch as blond continued humping and kissing him passionately. He felt soooo good, he wanted this big man in his ass and this slim boy in his arms forever... and with the thought he shot his load between blond boy's legs. He had of course had a couple months to adjust to the idea that he had almost immediate recovery so he just kept humping blond boy and allowed himself to feel the unstoppable prostate pounding of Black in his ass.
Soon Blond, and then Black, also shot loads, and abruptly there was an unexpected pause in the pace of the sex. "I don't know about you guys," Black growled, "but I was gay before GID, and we know a few things about mansex. Try this." And with that, in his hand he revealed a small brown bottle. Programmer and blond boy didn't recognize poppers having never seen them before, but Black opened the bottle and placed it under blond boy's nose and told him "snort it," and blond boy knew when to submit to the alpha male so he inhaled. Programmer, face to face with blond boy, was startled and delighted as blond boy looked surprised, then dazed, and a vacant, stupid smile took over his flushed face as he clutched onto Programmer tighter and started to hump even faster and harder.
"How long does it last?" Programmer asked.
"Well, it used to last two, perhaps three minutes," Black explained, "and it was a big head rush, but since GID it lasts for an hour, and you also get real stupid and mindless while it's happening. You just become a sex-crazed animal, and with occasional snorts - which you're almost certain to take in your stupor - you can stay that way for 8 hours before you need a break."
Programmer looked down into the dazed and happy face of blond boy, now wrapping his legs around Programmer and Black as he squirmed to move his ass onto Programmer's cock. He wondered what it might feel like to be high, stupid, mindless, and fuck like an animal. Before he could ponder it further Black growled "time to get stupid boy," in his ear and shoved the bottle under his nose just as he was inhaling. As he felt the blood rush to his head and an odd but pleasant pressure descend inside his skull, his last thought was "oh my" before his mind slipped away and his body started fucking blond boy hard in frantic rut.
Black looke down happily at his two playmates, enjoying the feeling of now-stupid programmer bucking back and forth onto his cock. Time to join the stupid club. Bringing the bottle to his nose, he inhaled a deep, hard snort, and placed it on the night table, open so the fumes would keep them all going.
In moments there was no more thought in the apartment, just three mindless animals in rut, pounding each others asses with their cocks for the night.
Representatives of the United States military services officially appealed to the congress and senate to repeal laws banning homosexuality in the ranks, which seemed only sensible now that practically everyone in the services was now gay. Requests for funding for substantial additional recruiting were denied, however, when it became clear that mostly they just wanted more members for the frequent barracks orgies.
The porn industry had a brief lot of fun making piles of new gay videos and magazines before it became clear that no one was buying, since everyone was too busy actually having sex to bother looking at pictures of it. The sex toy industry, on the other hand, was having a huge boom as soon as they could bring themselves to stop using their own products long enough to make more for sale.
In the morning the programmer finally started to come down from his last hit of poppers and return to conscious thought. The night had been a wild blur of cocks, asses, Black's muscle, blond boy in his arms, and an ecstacy of orgasm after orgasm. There was cum everywhere. He was held tight in Black's arms with Black's softening but still huge cock lodged in his ass, and blond boy was clamped tightly to his chest, dozing lightly. The programmer closed his eyes to enjoy the moment. Soon he'd get up and make a huge breakfast of sausage and eggs. It was saturday, and with these two in his bed he knew he had a hell of a weekend in store.
Fundamentalists screamed for the preservation of "traditional values" and urged everyone with GID to abstain from sex. They started remote colonies in the countryside of people who pledged thelselves to celibacy and christianity, but the colonies failed after investigative reporters found that all the men were sneaking out to fuck in the woods after dark instead of sleeping. Their appeals for public support mostly fell on deaf ears, because despite the massive logistical problems of practically every married couple heading for divorce, most everone was too happy with their new sex life and their new body to want to complain.
High schools, out of necessity, instituted short breaks for sex four times a day and replaced physical education with a full hour of sex. It didn't bring a halt to students skipping class to fuck, but it helped reduce the problem.
Men with GID couldn't decide for a while if they were now just attracted to all men without differentiation, or if all men had now just become attractive due to the muscles and cocks GID gave them. It wasn't either, exactly, but GID had rewired their sense of attraction so that most men could be attractive to and consequently enjoy sex with most other men. Between that and the super high sex drives, men found themselves having sex with all of their male friends and, for that matter, nearly any guy they happened to meet when they had time for sex or were too horned up to avoid it.
Sales of poppers quietly rose as word spread that they did amazing things for the Converted.
Doctors finally started to notice that people with AIDS who had contracted GID suddenly showed no symptoms and began to recover, even if they weren't on any drugs. The National Institute of Health reported that there had been no reported new cases of any sexually transmitted disease in anyone with GID, and random sample testing showed 100% negative results. They were astonished as they'd been expecting a high disease rate based on the sudden huge rise in promiscuity. The researchers were so delighted with the news they all went off to a conference room to celebrate by enjoying each other's cocks for a few hours. It would take a little longer to notice the disappearance of the common cold.
Nursing home populations fell as elderly men who were too old and weak to walk around found new bodily strength and new sources of fun in each other's no-longer flabby bodies.
In the Brooklyn loft, the Engineer looked at his calendar as he got a drink from the fridge and saw that Phase 4 was scheduled to begin the next day. Phase 3 had been a raging success. Opposition to the spread of GID had melted away as people took delight in their bodies and fantastic sex like they'd never imagined, and his program to bring poppers-soaked sexual frenzy to men everywhere was slowly succeding by word of mouth. However, Phase 4 would be a bit more extreme and he wondered how the world would react. Ah well, they had no say in the matter, his tiny creations were going to carry out the program to his tastes and no one could stop them.
The two men he'd picked up at the coffee shop were already getting stupid on poppers on the sofa in the living room. The Engineer decided he would hold off on that himself for a little while so he could keep his wits about him and use the guys to get what he wanted... and what he wanted tonight was oral. Lots of oral. He was going to suck cock and fuck face until one of the guys, starting to come down from their current hit, shoved a bottle in his nose and took away his ability to decide for the rest of the night. Phase 4 was coming, and everything would change... again.
