Your name is Anna, you're a twenty two year old university student studying to become a vet. This new job at the animal daycare was a dream come true for you, and you're first experience directly working with animals as a job.
You approach the daycare, it's huge, far bigger than you expected, and you can hear the sounds of many different types of animals. This was going to be even better than you thought, this place was practically a zoo!
Heading inside you are greated by a handsome man not much older than you, he introduces himself as Liam, he's the manager here and will be taking you on a tour through the daycare.
Liam takes you down the long corridors of the daycare, windows on each side looking into enclosures for many types of animals big and small. He explains that the daycare mainly looks after animals for zoos and farms, housing animals while renovations are done and even breeding some species for zoos without the proper facilites for it.
By the time the tour is complete it is already approaching the end of your first shift, Liam leads you through a door into an empty enclosure, you can see the hallway you came through on the other side of the viewing window.
Liam tells you that you paid such good attention that he has a surprise for you. You turn to see he has removed his pants, his huge penis hangs between his legs. You gasp, but your surprise is quickly replaced by arrousal as you unknowingly breathe in the chemicals being released into the enclosure from vents on the ceiling.
Liam explains that he wants to promote you to a member of their breeding program, and that he has been modified to help new recruits transition into the role. Barely listening you find you have removed your clothes, only noticing as your final item of clothing, your bra, drops to the ground.
Liam having finished his explanation asks what you think and you immediately agree to join the program. Unsure what's next you get your answer as your eyes fixate on his privates as his penis begins to pulsate and grow errect, as it does so it changes, morphing into an unmistakenly bestial appendage, his testicles soon following suit, bulging with cum and changing to match. Liam now has the cock of what animal?
