Meanwhile, Mike was struggling to climb down the fire escape. Everything felt so wrong. The air outside was fresh and clear, but all he could smell was the musty scent coming from the apartment window he'd left open in his haste.
"God...I have to warn the others. Grayson damn it, where did you go?" Mike said to himself.
Wiping some sweat off his brow, Mike finished descending the fire escape. He stumbled to the ground, and then edged along the alley wall. Only then did he realize he was completely naked. He'd torn his clothing off in the apartment. Worrying someone might see him, Mike hid behind a dumpster. He crouched down, hugging his sides and trying to ignore the raging erection between his legs. But it was a losing battle. He'd never felt so hot, or turned on. His hands started to migrate lower, until Mike was clutching his thighs and practically drooling over his hard on.
As he stared, his penis started changing. An average sized phallus, it started to lengthen until it was eight inches, and painfully erect. Mike couldn't stop himself, he had to get rid of this erection. Touching his cock, Mike felt his legs give out as pleasure overcame him. The head of his cock started spilling pre like the tap from a bathtub. Falling onto his ass, Mike yelped when he landed on something especially hard.
Momentarily forgetting about his arousal, Mike reached behind him to check why his ass was hurting so much. His fingers touched what he thought was a rather large bug bite. But then it started growing, and Mike knew something was very wrong. It didn't stop growing until the bump was two inches long.
"Holy fuck, is that... I'm growing a tail." Mike breathed. His fear killed his arousal, and his cock fell down. It was still bigger than it should be. And looked very, very wrong. Retreating back, Mike watched in horror as his cock disappeared into something he didn't have prior to entering the apartment. Peeling the skin back, Mike saw that his cock was now housed within a very animalistic sheath. Hairless for the moment, but inspecting his body further, Mike saw that his balls were now covered in dark gray hair. It was surprisingly soft.
Jumping to his feet, terror filling his chest, Mike knew he needed to get away from this place as soon as possible. He wasn't sure where he would go, or what he'd do. Within the next twenty four hours he'd be a sex crazed animal. A fate he wouldn't wish on anyone else. Well maybe one person. But Grayson was exposed too, so he'd probably be foaming at the mouth soon too.
"Serves him right, ditching me and John like that. Hope he gets turned into a rat." Mike growled. Standing on shaky legs, Mike looked up and saw someone was hanging their laundry to dry only two floors up. Scrambling back up the fire escape, Mike grabbed the first set of clothing he thought fit. The pants were a bit tight around his bizarre new cock, but Mike wasn't that particular. The waistband was also pinching his growing tail.
"Can't believe I'm saying this, but if it was full length at least it wouldn't be stuck like this." he thought. Shuffling along, still barefoot, Mike made his way back to the street. The patrol car that he'd driven to the apartment was gone, Grayson most likely drove off with it. Mike didn't have any ID or wallet on him, they were left in the contaminated apartment building. He knew if he went back inside the virus would only progress that much faster. So, embarrassed and worried he was only going to spread the virus, Mike walked home.

By the time he got home, Mike's erection tented out in front of him, as clear as the nose on his face. Waddling to the bathroom, Mike tore off his pants and saw that his erection had gotten bigger. In the time it took him to walk home, barefoot getting strange looks from onlookers, his dick had continued to transform. It was now fully canine. His time was running out, it wouldn't take long before he was standing on two paws, and drooling. Mike's balls were swollen and the head of his cock twitched with anticipation.
