You struggle against the spell with all your might. You can feel it working, it's roots growing deep within your mind and deep inside your body. An overwhelming tiredness overcomes your body. You slowly begin to lose consciousness.
You slowly open your eyes, and the first thing you notice is that every thing feels sluggish and slow, even your mind. Your body feels huge. You open your eyes and see the witch; "oh, good, your awake, can you still understand me?", she asks. The words were very foreign to you. You only understood about half of them, and even that took a great deal of effort. Looking at the witch you see she seems very small compared to you. You glance down at your new body and grunt in surprise. You were about 10 feet tall now, and covered in hair and muscles. You were completely naked and you had a huge cock hanging bewteen your legs! It was at least a foot and a half long, soft, and it was covered in a sleeve of veins and a thick leather covering. On top of all this, your skin has taken on a rough leathery appearance, and a strange greenish tint.
You stagger backwards, your huge cock swaying between your hairy muscular legs. The weight of it feels unreal! Just then, you feel a large pain in your skull. You reach up with your hairy hands and grasp your forehead. It feels like your brain is being squeezed! It hurt quite a bit. You feel your brain start to turn to mush. Complex thoughts, which were difficult before, were becoming impossible. As your brain shrunk, memories of your old life faded away completely. "Who was I before? Was I a human? Wait, What is a human?", you think to yourself, as the thoughts fade away, to be replaced with nothing. Suddenly the witch spoke, breaking you out of your stupor.
"Do you like your new appearance? You are my new swamp troll", she teased you, but your feeble brain could not comprehend the meaning behind her words. You realize with a start that you had lost all but the bare basic understanding of English. "What... I", you struggle to grunt out.
The witch smiles with genuine compassion; "Oh, is English too hard? I guess trolls are not the smartest. Somewhere about the IQ of a german shepard. Come here". Her soft hand graps yours and takes you too a mirror. You see your refletion and gasp. Your face has become horribly beastly, wth a huge bony risge above your eyes. Massive yellowed tusks stick out of your green skinned mouth. You look like an absolute beast! hge bony ridge protrudes out out of your foreheard, giving you a rather caveman like appearance. You grunt in fear. Just then, you notice a preassure in your groin. You look down and see that your huge leathery hose of a cock was streaming urine all over her floor. "Uhhh... Me.... Bad...", you grunt out stupidly, grapsing your cock and trying to stop the flow of piss.
"Oh, no, don't feel bad my new troll friend. Trolls are too stupid to be housebroken. I won't hold it against you!".
Slowly the flow of piss stopped. You stood there in a puddle of stinky troll piss, staring blankly at the witch with a dumb expression and a line of drool leaking down your hairy face. You scratch a hairy armpit, noticing it stinks to high heaven, annd let out a loud fart. A few flies begin to fly and buzz around your unwashed body, relishing your powerful troll BO.
"My my, you have certainly regressed far! Normally my new trolls are nowhere near this stupid or brutish. Oh well, you are still one of my trolls. I guess I will take care of you. But, you need to get out before you make any more of a mess or stink up my hut anymore! Shoo! Get out! There is a nice cave for you to live in behind the hut. There, you can live in yur stink and squalor!".
She herds you out of he hut and slams the door. You stand out in the open, very confused. What was she saying to you? Why are you here? It was all too difficult for your feeble brain to work through. You lazily scratch one of your huge hairy, grapefruit sized balls and then sniff your hands. You grunt. It smelled good. You let out another huge fart, turn around, and begin to amble around the swamp. Something in your small brain is telling you to find your cave; your new home!
