You quickly realize that Liam is now equipped with what is unmistakenly a bulls penis. He explains that they need to breed some Highland cows for a farm, and importing them would be far to expensive.
Confused but also horny from the chemicals in the air you ask Liam why you both need to be naked, and what he plans to do with his new equipment. He then reveals that you are to be the first of the cows, your already ginger locks will be a perfect fit for a mother in the new herd.
Liam firmly grabs you by the waist and turns you around, he tells you to get down on all fours. Realising what he plans to do but helplessly overcome by lust you obey, raising your petite ass and presenting him with your already dripping sex.
Wasting no time Liam plants himself in a firm stance, grabs hold of your hips and begins to insert his bestial appendage. You let out a scream of pain, the huge penis not meant for a human's vagina, but the pain soon vanishes as his cock sinks deeper and deeper as you begin to change.
Your vagina sprays juices as it begins to pulsate around Liam's cock, as it does it grows wider, your petite lips darkening to black and becoming thick and leathery, soon he has his full girth inside you. Not stopping there a tail tipped with ginger hair erupts from above your ass, as your asshole pulsates and expands into a dark donut shaped orifice.
Overcome with lust you barely notice the loud slapping of Liam's huge balls on your ass as it jiggles and expands along with your thighs, your rear now huge and still growing. Your entire body is growing in size, and just as your new weight starts to become too much your arms and legs twist and grow, your hands and feet rapidly hardening and twisting into hooves to support you.
You moan, drool dripping from your mouth as long horns sprout from the sides of your head, ears reshaping alongside them. Your neck thickens to support their weight. Long ginger hairs are beginning to grow all over your body.
Just as you think you couldn't be more turned on your breasts begin to jiggle, they bulge and pulsate, growing with every passing second, as they do they shift down the length of your growing torso and settle between your legs. Each breast then splits into two and the four breasts then merge together, turning into one huge udder, your nipples quadrupling in length to finalize the change. As soon as it finishes forming your udder bloats and grows taut with milk, droplets dripping from each teat.
As your new hair continues to grow your change nears completion, Liam is grunting with exersertion, his cock swells as he approaches climax, and only his tall frame allows him to continue mating with your now much bigger body.
You let out a last feminine gasp as your face pulls forward into a snout, your eyesight blurs momentary as your eyes move apart and the your nostrils bulge. You let out a drawn out moo as you complete your metamorphosis and smell the scent of your mates sweat.
Grunting Liam begins to cum, his cock pulsating as it ejects thick ropes of bull semen inside you, with each pulse your eyesight flashes with pleasure and your human mind begins to fade. After several intense minutes Liam falls back, his balls completely empty and his penis slowly changing back to human, but no such reversal will happen to you, you are nothing but a cow now. A fat, very much pregnant cow content with her breeding, and excited for her calf to be.
