A willing one?

Kazex smirked as he thought to himself. If he wanted to exploit the witch's inner slut he first needed her to tap into it herself as much as possible. The more she did herself, the less he'd have to manipulate. She'd help him turn her into a real **** without even noticing it.

" A willing one. Now to get started you'll drink this potion to make things more .... interesting" Kazex had a potion that can turn a human into a goblin. If she became a goblin herself the instinct to breed and submit would work wonderfully. "I thought it would make 'em more hot and..."

Helga raised her hand. "Stop right there! I don't trust your potions for anything.". Kazex shruged and drank from the bottle himself. His cock immediately became errect "see?" On a normal Goblin the potion simply served to stimulate their instincts, but on a witch like her it would make her transform into a hot, big boobed, wide hip female goblin. Once she turns, she will become a total breeding slut like any goblin female. At least that's what he hoped would happen.

Helga was surprised, although Kazex couldn't quite tell if it was with his direct action or how large his cock was. Finally she drank the potion and layed down in bed. She had her legs wide open for him to see. "Get over here and fuck me now!" Kazex stood there for a second with a raised eye brow. After a second she realized what he wanted and switched on the **** play "F... Fuck me please, Master"

He smiled going up to her. "If you insist, sexy!".

She moaned back putting her arms around his neck. "Oh god! Your so big where it counts. Now no holding back. Fuck me as hard as possible and give me all your seed." her inner slut leaked out as her acting blurred with her real thoughts. But while she said submissive words with her mouth her eyes couldn't hide their arrogance. Her moans even felt impassioned. It was clear he had a lot of work to do while waiting the potion to take full effect, which would take longer than normal due to her magical resistance.
