The feeling is indescribable, your vagina clamping down around Liam's cock, eager to milk every drop of his seed. Your eyes roll back in your head once more and your entire body shakes with the intensity of the climax that rocks through you.
As your body convulses with pleasure, your face bulges and stretches forward, your nose and mouth elongating into a equine muzzle as your cheekbones widen. Your teeth shift into the large flat molars of a herbivore as your fattening togue fills your mouth and you feel your eyes bulge in their sockets.
Waves of pleasure surge through your body as your womb bulges, full of equine cum as the contents of Liam's hefty balls are drawn up his immense shaft and ejaculated into you.
You feel your grip on reality slipping, each wave of pleasure rocking your body accompanied by a slight decrease in your intelligence as your mind begins to devolve to match your now fully equine body. With each passing moment your humanity is stripped away, your thoughts consumed by the simple need to breed.
With a contented sigh Liam pushs himself back off you, his cock slipping out of your equine cunt with a wet slurp as you whinny in pleasure. Without a cock to plug it a torrent of cum begins to bubble out of your still winking sex, dribbling down your haunches and onto your thighs.
Your human mind is almost entirely gone now, traces of your personality remaining but most of your intelligence already a distant memory as you akwardly fold your legs and lower yourself to lay on your stomach. You're no longer a woman, you are a mare.
His job complete Liam gathers up his clothes, his equine cock slowly shrinking at it returns to its orginal human form. He dresses as he briefly admires his handiwork, his gaze running up and down your new equine form. Once dressed, Liam throws your clothes into a bin near the door and leaves without a word. His thoughts having already turned to his choice of candidates for tommorow.
