Ty went with choosing a horse. His imagination suggested something with great strength, tall stature and a muscular frame. Ty already felt his feet merging and hardening into hard hooves. His ears started to point upwards and move from the side of his head to the top where is hair rests between. His hair grew out from his neck reaching to his back and his lombar as he felt a tail sprout right above his buttocks. His body was slowly engulfed with a short covering of hair. His face started to elongate, forming a snout while the sides of his jaw bulked and bulged out from the muscle. He could literally feel his voice deepen as his adam's apple pushed outwards against the skin. He let out a deep, beastly grunt in approval as his neck thickened out to an enormous width. He could feel sheer power pump into his arms. His veins engourged themselves with blood and pushed the muscle tissue to the maximum. The veins stuck out pumping testosterone throughout his arms. He felt his breathing become heavier. His chest pushed out in a fight with human size capacity. His nipples exploded outward reaching past half-dollar size and were pointing downward due to the growing muscle shelves they were attached to.
His torso chisled out a fourth set of abs like the grand canyon and all eight pushed outwards in a show of inhuman power. They glistened with sweat, moistening the muscles that were harder than steel. His ass inflated and hardened, each bowling ball size glute pushing outwards from sheer muscle. Ty felt his energy slide down his fire-hose dick, it too gushed downwards and then upwards as he became hard. Much as the saying goes, his cock managed to extend past the size of his own enlarged legs, both length and width. It shot out in growth and didn't stop until he was sure he could just barely fit his now elephant sized hands around it. He reached down and grabbed his balls, which were now the size of wrecking balls as he let out another animalistic growl of approval. His legs creaked and snapped as they pushed out and up like the great redwood trees. His calves pushed out, looking like someone pumped them full of tight air. The growth of his legs sent Ty straight up, making him taller than ever before, maybe even too tall. Ty managed to grow twenty feet in height and showed no signs of stopping. He began sweating profusely and panting. He cuffed his enormous pec and his enlarged cock head, feeling it fill more and more, never stopping.
