Alien Engineering

Cutting room floor: stories that never got finished because they're weird and experimental and don't connect to anything.

Cum.
 When the call first came, the world assumed it was a language issue. An alien probe had been spotted at the edge of the solar system, headed towards the planet from no origin that made sense. Every country prepared to receive it, every scientist was frayed from the anticipation. It approached for only a  week, a hectic, panic filled week, and when it arrived it shone in the sky for but a moment, gave but a single statement before disappearing.   
 Cum.
 Cults rose and fell, researchers of every kind argued back and forth, from any discipline coming so far to say so little made no sense and so some kind of hidden meaning MUST be there. Perverts said they knew what it meant, if you know what they mean, and were summarily ignored. It was something to think about, but nobody could make sense of it.
 Cum.
 Then the changes began. Only in retrospect did they begin here, at the time it all seemed normal. People were having sex more, they were probably just relieved that society wasn't changed forever. People were working out more, they probably just got a rush of perspective and felt fitness was more important. People were testing higher in testosterone, they probably just felt a species wide sense of dominance after seeing the aliens be so silly.   
 Cum.
 But it didn't stop. Global testosterone levels kept increasing. Global estrogen levels started increasing. Sperm count started increasing. Puberty started occurring early for nearly 20% of the young population. Men who were impotent ceased to be so, men who weren't went longer and longer. For the next two years, the entire population reached a minimum threshold that would have been peak sexuality a decade prior.
 Cum.
 Then the dicks started growing. Global average climbed to seven inches by the end of the first year. By the end of the second it was nine. Condom manufacture struggled to keep up. Porn stars with 14 inches burst onto the scene, then quickly found they weren't alone. The modern glory hole destroyed more bathrooms than ever before. Yet, against all odds, rate of injury from overlarge insertion decreased.   
 Cum.
 The testicles came next and brought the prostate with them. Cups were purchased in greater numbers than ever before. Nuts lost popularity as a euphemism as the average size was becoming far bigger than even the brazil nut. Trained lookers could see the bulge in the soft tissue from the internal prostate bulging out so far. Constant horniness, ease of stimulation, it flooded into the population more and more.
 Cum.   
 The studies showed that it wasn't going to stop on its own, but failed to show much else. The changes were greatest among porn stars, fetishists, researchers of the changes themselves, and researchers of the alien craft. The more they researched, the more they were affected, and the less they could research as their bodies took them over.
