The orc quickly moved towards you, a green creature who's musculature what that of a god - something greater than even the finely cut bodybuilders of today. His chest hair was dark and dense, with pubic hair like a forest. Between his legs rose a heavy dick, currently erect at a grim 13 inches. He was massive example of beastly masculinity. The Orc grinned, which only brought to attentions to the pearly white tusks poking from out his bottom lip.
Soon he stood over you, his must and sent overpowering you causing your loins to ache with begging pleasure.
"You're a small lad, I give you that." The Orc began, his voice deep and rich. "But lets have some fun. I need a good time, ey. What about you?"
The pounding in your dick was too much, the primal urges of flesh creeping over any logical urges to run or to simply resist. But how could you resist? The Orc then lunged onto you. You let out a wail, terrified as the Orc tightly held you against him. You shrieked in pleasured, consenting to the flesh immediately, as your puny cock grinds against his. Both of your members were already wet with sweat and pre, you yourself starting to rut against your partner's own grinding actions. You groaned and wailed, letting the sex take you deeper into the grip of the Forest. Your muscles began to tense and ache, pain overtaking you but quickly faded in a crashing wave of physical love. Suddenly you both reached climax, your skin becoming coating with your own juices - cum, sweat and skin.
You fell to your side, then crawled desperately away as the afterglow warmed you. You didn't last long, a sensation like masturbation kicking into your crotch. You moaned, collapsing onto your back. You muscles continued to ache, a fine but subtle definition creasing across your thin form. You became built like a runner, lean but with obvious signs of musculature. You felt your new, lean form with modest excitement, a part of you pleased with the change, and another terrified at the implications.
A twinge took your attention further downwards and watched your balls doubled in size, refilling with spunk and your dick springing into action. It itched and ached in terrible, but oh so pleasant ways. You grit your teeth and moaned again, watching the Orc look on at you with excitement.
Your eyes narrowed on your dick, throbbing and wet, as it too began to change...
It...
