Dr. Kennerson fell to all fours, shedding his clothing as quickly as he'd shed his human form. No longer was there Dr. Kennison, rather only a large German shepherd where the good doctor had been moments earlier. The former doctor growled at Mark, advancing slowly on him. Mark took a step back, worried about infection or attack, not realizing he'd probably been infected the moment he came to Bryan's rescue.
Bryan hopped off the table, standing in between Mark and the doctor, protecting him. Apparently he still retained a vestige of his human memories, Mark realized.
Suddenly, the door opened. It was Amber, looking flushed. "Doctor, I...I'm not feeling so...so well.." she said as she walked in. Mark could tell Amber was beginning to change. Her arms were covered in a thin layer of golden fur, growing thicker while he watched. Her body glistened with a thin sheen of sweat as the infection took hold and modified her genetic makeup.
The doctor was no longer concerned with Mark, immediately turning on Amber, burying his face against the fabric of her skirt, eagerly attempting to put his muzzle into her crotch. "Uhhnnnn.." she whimpered. Mark heard her clothing begin to tear as she changed quicker, fueled by her arousal.
Amber tore frantically at her clothing, eager to be free of its confining prison. Mark watched, transfixed as Amber, still quite human gave into her primal urges, raising her ass in the air as it bloomed a tail. "You...mate!" she growled at the doctor-shepherd through a fang-filled mouth, dripping musk from her twitching and reshaping vagina.
Mark felt almost horrified at himself when he got hard. But he couldn't deny the erotic allure of Amber, now growing extra breasts as the shepherd banged her from behind.Seeing the changing woman made him grow impossibly hard, and he had to resist the urge to stroke himself.
As he watched the mating frenzy, Mark decided he needed to try this for himself. Obviously, any female infected quickly went into heat. Mark wanted to know what it felt like, to slip his cock into that twitching, shifting mass of a dog-woman's vagina. He wanted to know very badly.
"Come on, Bryan," he said to his friend," it's time to go pick up some chicks." He slipped out the door with Bryan, shutting the former doctor and nurse in the office. "It's time to get some tail," Mark said, laughing at the new literal meaning of the phrase.
