The chronivac sat on his desk ask Jeffy if he wanted to be even sluttier, he was already at a 100% slut. How much sluttoer could he be? What was left of his brain cells wanted him to decline and go back to the way things were to being a normal average boy, but the slut that he is now won and he pressed Yes
...
Jeffy's ass was the first to change it was already the size of watermelons from the first change but now it grew to the size of beachballs. He could really open up his hole and let anything in, multiable stuff even. His ass would set so that if anyone was in viewing distance of it the would immediately get a stiffy even if they weren't looking directly at it. His lips grew wider allowing more sucking at once.
Jeffy decide he needed to go shopping for sluttier clothes so he put a shiny light blue barely there thong as his wardrobe knowing no one could resist him and he could get away with anything.
...
As he walked outside a lot of cars had to stop to deal with their growing members between their legs. In one car sat a 10 year old boy named Tim who was feeling awkward that his peepee was growing for the first time. His dad was dealing with the same issue in the driver seat. Later that night Timmy was on his tablet looking at pictures of naked men, he was smart enough to change if his mom walked by but would immediately go back to looking at hairy chested older men having their way with boys older than him but still look to young to be doing what they were doing. His stiffy never went down. As for Dennis he went bed with strange feeling he couldn't place but would only occur when Tim was in his presence. That night Dennis had reoccurring dreams of fucking young boys, he couldn't stoping dream of putting his dick in their sweet innocent asses. Tim was having the same dream only it was hairy men fucking him in the ass as he was suck another one off. The next morning's they were eating breakfast the both had a look of horror and disgust but also a look of longing and knowing that if Tim's mother were to ever go out they would fall into their slutty desires. What they don't know is that as Jeffy had past them that day they were hit with jeff new pheromone that made them want and have these slutty desires forever changing their lives.
