Your body hair had already began to darken. If you could see your hair, it was rapidly darkening from the roots upwards into a pitch-black colour.
"What the hell is happening!?" The friend who had come towards you, Tobs, cried.
He stumbled back in shock, watching your naked from quiver, snap and twist under the glow of the full moon.
Your stomach heaved and quivered as it began to boil and ache. You could compare yourself to a sealed kettle now fizzing with strength and hot air, but having nowhere to release it. You could feel this sensation build and almost push your body. Your limbs began to spread out, growing longer and leaner. You watched and stared at this happen in sheer terror and heart-pumping excitement. You sat up and rested on your knees and watched as your fingers began to stretch and expand into long clawed things. It was here you realized how itchy your skin was becoming.
You eyed your forearm, watching the once faint hairs slowly becoming black and long. You grimaced at this, the sensation strangely unpleasant, which admittedly would late humor you when you reflected all the other changes to come. As this was happening your legs were slowly becoming hairier and shaggier and they too grew longer. Your muscles ached at all this, and your saw your body blossom with strength. Your pecs swelled to a dramatic size and your waist shrank and shoulders broadened, giving you an extreme 'V' shaped waist. By now your pubic hair was a dark and shaggy bush, growing and inching a itchy path up your navel, which pulsed and vibrated as it became defined with muscle and a strong set of abs. Suddenly and dramatically this trail of hair shot upwards and exploded across your swelling chest. By now you had a beard like layer of hair, or perhaps near-fur, as your natural hair follicles were stimulated to the extreme. However that would soon change and now your entire skin, including your back, feet and face began to grow a shaggy layer of hair.
By now you were an incredibly tall and lean but strongly muscled humanoid with a wolfish face covering in thick body hair, like someone with a increasingly potent case of Hypertrichosis. However, the inhumanly long claws and your lengthening, clawed feet and monstrous face would change that observation fast. You were growing the build of a long distance runner with massive and thick hairy thighs, but with shoulders too massive and a toro fit for a body builder. It was this dramatic contrast of body types and monstrous features that made it clear you were not human.
You began to growl now, feeling your fur thicken and your muscles became stronger and even more defined. You began groaning as your face snaped and cracked into a muscle, the final snap sending wild and new urges across your new form. You clamored up to your pawed feet, standing tall at 7ft and you howled. It was a deep and primal how that made everything feel good, strong and right.
It also sent chills down the petrified Tobs who looked on in silence.
You snapped your wolfish attention towards Tobs and began to crawl forwards towards him with a grin.
