This story happens in the future. A sci-fi future where genetic engineering has become much more advanced than it is now. In this future there was mad scientist that created a new STD and released it into the population. The SDT only spread through the cum of young gay guys. The government constantly tried to stop the virus from spreading but most gays thought the STD was a glorious gift and fought hard to get themselves infected and to keep spreading the virus to others. It took two weeks for most infected individuals to become immune to it. After that they would lose the special cum it gave them. The virus never actually made anyone get sick but instead it caused those that were infected to start producing special cum that altered the bodies of those that consumed it. The way it affected their bodies depended on their sexuality. The cum from submissive guys would do nothing to themselves or each other but it would make dominant guys grow more endowed. The cum from dominant guys would do nothing to themselves or each other but it would make any submissive guy’s entire body shrink smaller. All the effects were completely permanent and irreversible. The potency of their cum varied a lot from person to person. Only a few hundred guys had been infected so far and but the story of the virus quickly became world news.
One day at high school we all became extremely excited because we heard a few student confess that he just got infected with the virus and was planning on having an orgy party at his house that weekend to spread the virus around. Some of the sub students quickly made deals with dom ones so that they would take care of them after they shrunk. Usually the doms would make the subs agree to be their sex slaves for the rest of their lives in exchange for taking care of them but the deals varied drastically.
I decided to go to the party that weekend and eat as much cum as I possibly could. I arrived at the party that weekend a little bit later everyone else after the virus had already begun to spread. Some lesser experienced guys went to the party not realizing that they were subs and were horrified to see themselves shrinking down after swallowing someone’s load. Most of these guys ran out of the house scared and humiliated and ended up being about one foot shorter than their normal height.
