Goblin transformation potion (but it's slow and not perfect)

Kazex decides to use his potion to turn her into a female goblin. Part of him is not sure that he perfected the potion, but he is too turned on by the idea of turning that haughty elf into a goblin to care.

The goblin goes to his alchemy lab and starts brewing up the potion. He quickly finishes it and makes the elf drink before she regains her full consciousness.

That **** ingestion wakes her up, and she starts getting agitated.

"Free me, you little rascal, or I'll give you a painful **** !" She yells at him.

For now, no changes appear in the elf, which makes Kazex doubt of his work. But then, he noticed the tip of the elf ears slowly turn green. It's a small change, but it's proof it works.

"Do you hear me? Or maybe... maybe you're to dumb to... to understand..." She continues to yell at him.

But clearly, she's having difficulties to focus, and her gaze looks far away as her anger fade.

"I hear you." He cuts her.

"Uh? ... Uh, you think these cuffs... these cuffs... what's going on... it's so hard to focus..."

"It's the changes."

"W-What do you... mean ?" She asks, frowning.

"Soon you'll be like me, slut." He just answers calmly.

"You dare... dare call me a... a slut... I'll never be..." She squirms, her anger still surfacing through her feverish state, but stop quickly, noticing something.

Looking down, her almost non-existent tits, typical of the elves, have grown big enough to be bouncing a bit when she moved. Her nipples had also turned from a cute pink to a light brown.

"What... What did you do... ?" She says, breathing heavily.

"I tried a potion that I made, it doesn't work as fast as I wanted but, it's working."

The elf's pussy starts to drool on the floor, while her fingers and toes slowly turn green. She's breathing heavily and become restless, rubbing her thighs together, probably to rub the itch off.

"You're already turning into a slut, I see."

"Fuck you, I... I'm not some... depraved tramp, I can... I can control myself."

"Ahah! No, you don't!"

Kazex free the elf, knowing she's too horny to try to escape, and as expected, she immediately reaches her pussy. Rubbing her clit furiously.

"You deviant monster... I-I can't stop... I can't stop rubbing my... my fingers on my love button..."

"I thought, you could control yourself."

"This is... this is too strong... I can't... I can't believe this..."

Kazex smiles at the distress of his prisoner and comes closer, his large cock on display.

"Do you want some help?"

"Get... Get away from me, asshole... AaaaAAnnh... look at what you... you make me say... Mmnngnn... I'm... I'm going to... AAaaAaannh..."

The elf 's pussy suddenly violently project a transparent liquid, squirting all over Kazex's feet. Exhausted by the huge orgasm, she loses consciousness, while convulsing randomly.

"This is going to be fun..." The goblin says as he leaves her and close the door of the cell.
