"Hmmm, I Know!" The grown Alex said as he began to stroke his cock. The skin of his balls began to darken as did his growing dick.
Chase couldn't help but moan as he tented his own pants, watching as Alex's penis grew larger and larger.
"Why don't you take those clothes off boy?" Alex commanded.
Chase quickly complied, soon naked, body sporting new hairs that hadn't been there that morning, his erect dick sticking up, slightly deformed. The tops of his ears were hairy and folded over slightly.
Chase sat mesmerized like a puppy he watched as Alex's penis grew thicker and longer, the head compressed and flared into that of a horse or donkey.
Alex spoke as Chase panted, "Ok, you can have it!"
Chase instantly shot forward onto the floor, face planted on the end of the pulsing member, his three inch retriever tail wagging furiously.
It only took a few seconds for Chase's longer tongue to coax a response from Alex's manhood and Chase soon was swallowing a mouthful.
Chase lifted himself up and sat back down, wiping his mouth before closing his eyes and shaking his head. "What the fuck did I just do!"
"You did well boy!" Alex said as his cock began to slowly soften.
The cum quickly flushed into Chase's body, a new version of the virus combining with the other. His dick felt like it was going to explode, it was so hard. He watched as his pink canine shaped member gained size and the thin membrane began to darken into a mottled dark skin with pinkish spots. The size soon matched that of a donkey, but mostly retained the shape of a dogs.
A mix of brown fur began to grow along with the gold, moving up his barreling chest. Chase moaned as his legs began to bend and fold more like dog legs, but remained long. At the end of his long dog paw shaped feet, black coated hooves began to mold.
Chase's back and torso began to lengthen and pull, causing him discomfort. Leaning forward seemed to help, but he soon found himself falling over and standing on hairy hands and hoofed feet.
Alex sees Chase's back is also covered in the blond brown fur mixture, with a brown cross between his shoulders and down the middle. Above his ass his tail had grown to full length, but has the structure of a donkey's with short hairs until the end, but the tassel looks like the end of a dogs tail!
The fur began to fill in on his arms as they lengthened to be symmetrical with his longer torso and hind legs. Black pads formed on his palms as his fingers shortened and black nails pushed out. His new paws also grew larger to compensate for his larger than normal body.
Chase now had the long hairy ears of a donkey but they hung down like the ears of a retriever! His face was growing outward as his long doggie tongue hung out of his big donkey teeth. The rest of his face became a merge of donkey and dog, a big wet black nose at the tip of a long face.
Chase both barked and brayed as his form was completed, he was now almost donkey sized but looked more dog like with some interesting donkey features.
Alex just laughed as he saw his finished creation, 'I've created a new species! I will call you the dogkey! You are kinda cute."
Just as he said that the van was coming to a stop, they had arrived and Alex had to do something fast!
(Anyone give a shit about this anymore or should I just give up?)
