You find you are unable to look away as you stare at Liam's now obscenely huge penis bulging at full-mast in front of you, the huge and clearly equine member out of place on his still human body. With the length and girth of a grown man's arm the cock's mottled shaft ends in a flared head that is already beginning to leak juices from its tip with every aroused pulse that travels its length, beneath hangs a dark, leathery sack, the orbs within already the size of tennis balls as they continue to swell with what can only be horse cum.
"We have a client in need of a new breeding mare for their racing business" Liam explains to you as he slowly closes distance with you, your eyes still locked on his swelling ballsack. 'You're the perfect candidate for the job" he says, snapping you out of your staring as he runs his hand down your thigh. Confused you ask him if it will be your job to look after the mare, trying to ignore the growing wetness between your legs as you have to again drag your eyes away from his cock. Liam's only response is a small laugh as he gently spins you around and pushes you forward so you fall and have to brace your hands on the glass viewing window of the enclosure.
"You're misunderstanding the role you only just agreed to, tsk tsk tsk" Liam chides you, you feel his hot breath on your neck but you don't turn around. Smack! suddenly Liam slaps his hand against your ass, sending tingles of pain and pleasure up your spine as you squeal in shock. "Still... the client doesn't really need you to be intelligent, your new job won't require it" Liam mocks, as he traces a finger down your spine.
You struggle to think of what it could be that you have misunderstood about your new role, but the fog over your mind and your ever-increasingly levels of horniness are making it hard for you to focus. Smack! Liam slaps your ass again, and you finally lose control as you squeal again and push your ass back, wedging his manhood between your ass-cheeks as you start running your soaked pussy lips up and down his equine shaft, shamelessly moaning in pleasure.
"Patience, you're going to be a fine mare" grunts Liam as he grabs hold of your hips to hold you still. Confused and annoyed at the interruption you turn your head and look back at him, unsure if you heard him right. "That's right, you won't be taking care of a breeding mare, you're going to be a breeding mare" he confirms with a grin as you suddenly realize what Liam's modified penis is really for and you wonder how many of the animals in the other enclosures used to be human.
You try to fight through the fog still clouding your mind as you will your body to flee but Liam leaves you no time to pull yourself together, widening his stance in preparation he moves into position to enter you. Staring at your own flushed face reflected in the glass you wonder what you're going to look like as a horse as you grit your teath and brace yourself for the ineviatable.
