The nurse smiles brightly as she explains "We have a treat for you as well" The door opens from the back of the room as a young 15 year old girl is pushed into the room. She is completely naked as you look over her. Your new equine cock throbs as you see her. She sees you as she bends over in slight pain, holding up with her hands on the floor as you see that she has something poking from her rear.
In all of the confusion the doors slam and lock, leaving only you and her in the room. The restraints loosen as you run to her trying to help as you stop in almost horror as she looks up at you, her ears elongating and her face starting to stretch. You introduce yourself "Uhm... I'm Benjamin" She replies, trying to say her name "A....Amanda"
She stands up as you can see her chest becoming more of a barrel shape. Brown fur starts to rush over her chest and belly as you look down, your legs begin to enlarge with huge muscles, also growing brown fur. All fear is lost when you both realize that you will have each other.
Amanda grabs Benjamin's throbbing equine cock as she explores a little. She cant stand on her own two feet as she falls on all fours. A voice comes over an intercom "now Benjamin, make us proud." Her changes are quicker than yours as her tail extends fully, growing the long strands of her tail, the fur spreading faster as her feet mold quickly into large hooves covered with the horse fur. Her torso widens and becomes barreled shaped as the fur completely spreads around her. Her hand mold into large hooves as well as the fur races up her arms and past her chest, to her face which is now extended fully.
You stand there amazed and horny as ever, next to the beautiful Clydesdale mare, in all this you did not realize that your feet have also molded to huge hooves. You move across the room to her, placing your hand at her rump as you watch your hand change as well. You place yourself behind her.
Your rear increases in size exponentially as your body gains height. You fall over her body as you slightly slip your huge equine member into her. She squeezes down on you as you see your face extend, the weight of the mane forming along your neck and head as you thrust. Manda whinnies in delight as she clenches harder around you. Your tail starts to burst out above your anus as you lift it high and proud.
The voice comes back on "There you go Benjamin, fill her with your equine seed, you majestic Clydesdale." You feel your seed churn deeply inside you. You pump a few more times as Manda's tail flicks under you, you shoot long strands of your hot horse seed into Manda's tight equine body. She cums as well, clenching very tightly as you slip out. She turns her huge body as she sniffs your member, you reach around with your large head, rubbing at her rear as you flick your tail.
The intercom comes back on "now you both will follow through to the next door, which will open up into......
