Alex stopped dead and felt under his shirt again. He had been smooth-chested this morning. Which meant... he was infected. With a sigh, he turned around and headed back to Eric's. His friend was scared and alone - maybe it would help both of them to share the changes. He pulled out his cell and punched the button for home, noting that his finger was a little darker and coarser looking. "Hi, Mom? I'm going to spend the night at Eric's, OK? He's feeling a little down, and I figured some company would cheer him up." Luckily, it was not unusual for the two boys to spend nights at each other's houses, and his mom told him to have a good time.
Eric was surprised when Ale came back so soon, and upset when he revealed why. But he was also happy to have company. As soon as he shut the door behind Alex, he yanked off the clothing he had biding his mostly gorilla body and sighed in relief. Alex grinned. "Well, I guess you are mostly covered in hair, but dude, you are hanging low and loose!"
Eric shrugged. "We're gonna be animals soon. Me first, I guess, but you in a few days at least. We might as well get used to it. Anyway, it's not like we never saw each other naked before."
Alex hesitated, then pulled off his own clothes. As he suspected, his chest was covered in dark hair that was suspiciously like Eric's. His friend came over and brushed a coarse hand across the new growth. "Just like mine started."
Curious, Alex ran his fingers through the dense fur covering Eric's chest. "Do you feel different? I mean, well, like you are an animal?"
Eric shook his head. "Nah. I feel stronger, and way more flexible." He demonstrated by sitting on the floor and taking his own cock into his mouth. Alex stared. "Dude! that is so gross!"
Eric grinned. "Feels good, though. Instant service, and way better than beating off."
Alex recalled seeing chimpanzees and apes at the zoo, sometimes even drinking their own piss. It seemed really disgusting, but they were animals. He looked at his hands, noticing they appeared darker and a little thicker. "We are really turning into animals?"
Coming over on all fours like a gorilla, Eric sat next to Alex and pulled him into his lap. The former teen was bigger than Alex now, and pulled the boy into a hug. He smelled much like a gorilla now, a strong, musky odor that Alex did not really mind. But the itching seemed to get worse, and he was shocked to discover fur visibly spreading on his arms!
"Eric! I'm changing faster!" He struggled to pull free, but his friend was much larger and stronger.
"You are mine, now." Eric's voice was deeper and guttural, the words grunted out.
