Not quite. The thing about viruses is that people recover.

Jessie pat her belly and groaned from the stimulation of her newfound fertility. The morning sunshine gently peeked in across the sweat soaked family, causing the mass of bodies to gently twitch. The infected family looked at one another, the wild experience having forever changed them, but it felt different in the light of a new day.

They all felt a little feverish, their rapid and unreal transformations had completely warped them. But there was still a lot of viral load in their system. The initial changes had been rapid, but in the light of a new day, Jessie noticed that her hips were even wider, and by the looks of things, she wasn't the only one exhibiting a few alterations. Parker had already been impressive the night before, but now it appeared that the virus had affected his body more than expected. Her older brother rubbed his eyes moving his hands down his muscular body to grasp the pair of cocks standing proudly against his belly.

Her mom was still heavily pregnant, but now also had a second pair of breasts and a set of cow ears complete with fur. She looked even milkier than before and her babies would be positively bursting with the full virus in their genetics. Jessie wondered if they'd be as depraved as their parents. She knew somehow that her whole family had picked up a strain that specialized in breeding.

Hank's genitals were almost Coke can thick, and his massive balls would make wearing pants a losing battle. He'd lost a bit of mass, her father now looked a little like a pubescent boy save for his massive manhood. It made sense, the virus had to make all that yummy cum out of something. At least it hadn't messed with his body too badly.

Jessie grinned as she surveyed her family. They were all so perfect and still infectious for at least a little while. The more sex they had, the more things changed. Once they were recovered, they wouldn't change any more. She heard the Master's voice far away but the distance made it a dull suggestion rather than a command. The virus was spreading and with its rapid mutations, his voice would be gone once they recovered.

Rachel had also changed, sporting a long furry tail and a pair of chestnut red ears. She was pregnant too, and by the looks of it the whole family would be birthing soon. Jessie grinned. The neighborhood was theirs to infect. Maybe the virus would make more broodmares, maybe they'd get a wetnurse. All she knew was they weren't finished yet. She knew they needed to spread more before they stopped changing and spreading.
