"Absolutely not!"
Claudia had expected some quibbling, but not an outright refusal. Especially since they were between a fantastic meal prepared with the objective of indulging Laurent and the after-dinner promise of an evening of abandoned sex.
Faced with his hesitation, she rejected turning combative. "I know it's different..."
"Different?" Laurent scoffed. "You want me to change into an ass for a week! I'd say that's different."
"Those books must be worth a king's ransom, my love," she reasoned with him. "Think of the price he's willing to pay just to transport them."
Laurent had always been raised in the city, unlike Claudia, the daughter of farmers.
"They're smelly," he argued, wrinkling his nose at his only associations with donkeys.
"The books?"
He frowned. "Donkeys!" He said with disgust. "And they make that god-awful braying that sounds like they're being tortured."
Claudia laughed, but she thought about the hardscrabble animals back at the stable master's pen. "Well, some of them are like that," she admitted.
She stood and walked behind his chair, leaning over until her breasts pressed against him.
"I think you're scared of a week's work." She massaged his shoulders. "Big, strong...lazy man."
"I'm not lazy!" Laurent felt his cock twitch from her hands on his shoulders.
"I've already thought of a clever way to make this work for us."
Laurent's cock became attentive to her touch. "How?"
"I've worked a spell on a bag of oats," she started to explain.
"Good. Turn them into an ass..."
"The oats are for you, silly," she said. "When you stop for the first evening, the merchant will feed you from those oats. I will give them to him, no charge, and tell him I like my donkey fed well. Allow time for him to depart the scene, eat the oats, change back to Laurent and grab as many books as you can."
"If those books are so heavy they need a donkey to haul them..."
"Hide them," she said. "We'll recover them later."
"This sounds complicated." As he spoke, he noticed his cock still getting harder and hoped they could stop discussing and move things along to the bedroom.
"We'll also have the money the merchant paid me for you when he returns empty-handed and has to admit he lost my property."
"You're so devious," Laurent said and pulled Claudia into his lap.
She felt the rigid firmness as his trousers began to have difficulty confining the cock.
"Let's go...haww..." Laurent said. He felt a jolt of schock when he heard the odd noise exit his mouth.
Claudia stood, unperturbed, and knelt down.
"I think we better lower those trousers..."
For a moment, Laurent expected something else. But he felt strange as he began to experience a cascade of changes.
"Claudia!" He felt her loosen the trousers and tug them down. "What have you.... heee-hawww... done?"
A huge, black cock swung out just as a dense pelt of hairs began to sprout all over Laurent's normally only moderately hairy body.
"Thanks for eating all your vegetables," she smirked. She had permeated them with the potion now affecting Laurent's form.
Laurent leaped out of the chair and looked down. His cock had grown to an unimaginable length.
"Let's try to salvage your clothing," Claudia said and lifted one of his boots and tugged it off his transforming foot.
Laurent looked down in astonishment as she worked off the other boot. By the time she removed it, his foot had already mostly changed into a dark, blocky hoof.
"You... hee-haww... did it!" Laurent accused. "Without even asking!"
"The merchant's going to be here at dawn," she excused her actions. "I wanted to make sure everything's ready for him."
Laurent suddenly groaned as immense pressure wracked his spine, forcing him to fall onto all fours. Before his fingers and hands reached the floor they had fused into hooves, too. As his new hooves hit the floor, he felt a different sort of pressure at the base of his spine that signaled the sprouting of a ropey tail.
Claudia watched in amazement as her handiwork accelerated its changes. Laurent's handsome face morphed into a long snout that ended with two wide, flaring nostrils as he snorted in an attempt at denial. He looked at her with dull, wide eyes on each side of his elongated face.
His new hooves clomped on the floor and he shook his head. He felt the attachment of two enormous, hairy ears atop his skull.
"Eee-Haw!"
"Don't get cross with me, love," Claudia snapped right back at him. "Remember, it's only for a day. Eat the oats, you'll be back to me in no time."
He brayed again, horrified that the sound now appeared to be the only one he could produce.
"Now let's get you out to the barn," Claudia said, draping an arm around his neck and trying to persuade him to head toward the door.
When Laurent, no surprise, tried to stubbornly decline, she retrieved a simple rope bridle. She smiled as his instincts surfaced almost the instant she fixed the bridle around his head and snout. In moments, she had ushered him from the home and into the nearby barn.
"You'll have my undying affections for this, my love." She planted a soft kiss atop his bristly snout.
He only brayed again and marveled at how Claudia always seemed to get her way.
She soon left, closing the heavy wooden door behind her. Laurent, on all fours, stood on the hay-strewn barn floor and looked around him.
"Hee-haww..." burst from his wide, pendulous lips instead of the intended words, "Damn you, Claudia!"
