Drink from the vial of yellow liquid!

You hear the guards talking in goblin right outside the tent! Your hand shakes as you reach for the potions indecisively. They're opening the tent flap!

You grab the yellow vial and unstopper it with your teeth. you pour a thick, greasy drop of the unnaturally yellow liquid onto your tongue. It smells faintly of mint and you feel it tingling in your mouth. You swallow and warmth spreads throughout your body.

"What you doing!?" demands the angry guards as they enter the tent.

"Stay back," you warn, feeling the heat move lower, "I've swallowed the potion of demon strength...I'll..."

You cry out in pain and stagger against the alchemy workbench as pain shoots out from your clit. You feel to your knees and gasp to breathe. Your clit is throbbing. It feels as if someone has pinched it between fingers of steel and they are pulling and twisting at it.

"Hahahaha!" the guards laugh at you.

You look up at them, tears of pain in your eyes. You gasp at the feeling of your distended clit falling heavily onto the furs covering the floor. You've just swallowed a potion of male virility! Your clit has been transformed into an enormous prick, dangling between your legs all the way to te floor. Your vagina remains intact below it.

As the guards laugh and jeer Zakrog awakens and sees what has happened. You can do nothing. The sensation of the furs and the cushions rubbing against your new cock are too much and you find yourself grinding into the cushions, your butt humping up and down as you thrust into the soft, silky fabric. You gasp, your mouth hanging open with lust, and you cum into the cushions, spewing out a massive load of hot cum that shudders up the length of your new prick.

You pass out from the pleasure and awaken shackled in the tent, your chains hanging from the center pole and your body - and enormous cock - dangling like a side of meat. Zakrog is dressed and inspects you with his finger tip. Even that touch is enough to stimulate you to arousal.

"Magnificent," Zakrog says and looks up at you proudly. "It's meant ot last only a night. A bit of entertainment for me, to watch a beautiful human rut with my favorite slaves, but you've swallowed enough to last a week."

Zakrog snaps his fingers and the tent flap parts. You lift your head to see the girl who told you to take the demon's strength potion entering. She sheds a simple robe and reveals a shapely body with mother's breasts and fat nipples. At Zakrog's urging she drops to her knees and lifts your straining meat in her hands. You can't stand to look at her as she stroke you. It feels so incredible, so sensitive. She skins it back and her lips close around the head and you cum immediately, your hips working as you spew an enormous load into her eagerly sucking mouth.

"Yesss," Zakrog hisses.

She sucks you until you whimper from the sensitivity and then she begins licking you clean. Your cock only relaxes for a moment before she has you hard again, her soft breasts surrounding your cockmeat as you thrust into her mouth, betrayed by your own lust.

"I'll enjoy this show until you can't stand it anymore," Zakrog says, stroking your thigh. "Then I'll enjoy it some more. But I know who I'll be asking to bed my slaves when I'm too tired to do so."

His laughter echoes through the coming days and weeks. You please Zakrog yourself on many nights and he celebrates your firm body and beautiful face with fountains of his goblin cream. On other nights you are given a single drop of the elixir and made to bury your swollen cock in the mouths, cunts, and between the cheeks of all the various slavegirls. You hold their soft bodies in your arms and kiss them and feel strong as you thrust into them and explode.

You grow to enjoy it and long for the nights you will experience such pleasure. Some nights Zakrog even pleasures you himself, using his mouth or stroking himself as he watches you stroke yourself, allowing you to spurt your cum on his body. He does such things in secret to avoid the ridicule of his guards. Goblins are very sensitive to such things having traditionally been the abused laughingstock of the brutish orcs.

Your life as one of his favorite slaves takes you deep into the desert where Zakrog's nomad goblins dwell. There you remain safe from the strife that encompasses the world. Rising sore from a deep ass-fucking you are taken to the harem tent where the other **** girls are kept, but as you emerge form Zakrog's tent you see smoke upon the horizon and the dust of cavalry. You know the dark lords have found you and soon the undead will descend upon the goblins and feast upon them and their human slaves.
