"Wait, why am I walking?" Sarah stopped outside her house and asked herself. Gripping the rock tightly, she said, "I wish I was in Karyn Walker's kitchen."
Jon watched as Sarah's form shimmered, then disappeared with a flash of light.
Sarah found herself in a small, messy room with white walls and cupboards. Spotting a sink and a fridge, she reasoned she must be in the right place. Then she heard Karyn's voice, coming from the next room. By opening the door slightly and peeking through the crack, Sarah saw that Karyn was talking to her father.
After checking she still had the stone in her hand, Sarah threw the door open and made a wish before Karyn even had time to express her surprise.
"I wish you'd both do as I say until I leave this place! Now don't move!"
Sarah felt the rock glow, but paused for a moment to see with her eyes if her wish had succeeded. The kitchen door slammed shut behind her.
Karyn tried to move, but found her legs wouldn't obey her. "Sarah?? You have the rock?? What's happened to Jon??"
Sarah laughed. "A great deal has happened to your friend, Karyn. I'd dare say even you wouldn't recognise him the next time you see him!"
"You monster!! You heartless-"
"Now now Karyn, surely you must have already figured out why I'm here. You're not that dumb," Sarah giggled. "Maybe that's something should change? But your curse will be so much more delicious if you have your usual mental faculty..."
"Do your worst," Karyn said, bravely. Sarah noticed a tear roll down her cheek.
"Karyn, do you know this girl?" Karyn's father, Stuart, asked. Stuart looked old beyond his years, as the stress of raising the kids after the untimely death of his wife had taken its toll. Where once he was athletic and handsome, now he was balding and slightly overweight.
"Yes, she does Mr Walker," Sarah replied in Karyn's place. "My name is Sarah McMillan, I have a feeling you'll remember it."
Sarah turned to Karyn. "Because you asked so nicely," she said, "I think I will do my worst!"
"What are you talking about?" Stuart asked.
"Dad, Sarah's got a magic rock that makes all her wishes come true!," Karyn said. "She's gonna do something horrible to me!"
"Not just you, my dear," Sarah replied. Turning back to Karyn's father, she said, "Mr Walker, please stand up and come over here by me."
Stuart's body moved against his will, leaving the sofa and walking across the room to stand near Sarah.
"Now take off all your clothes! Let's get a look at you!"
"No!" Karyn protested. She didn't want to see her dad naked, but she couldn't look away.
"I can't help it Karyn, I'm sorry," her father said as he removed his shirt, exposing a very hairy chest and back. Then he removed his trousers and underpants in one motion. Sarah giggled at the sight of his penis as he pulled off his socks.
"Okay, now that pathetic little thing has got to go!" Sarah smirked. "I wish you had a big, hairy, fully functioning pussy instead of that pathetic cock and balls hanging between your legs."
"What the? Arrgh!! That hurts!" Karyn's father grimaced in pain as his dick folded in on itself, the tip turning inside out and plunging into the flesh of his member. The hole widened as it hit the base of his dick and sank into his crotch. His scrotum was drawn in like a loaded fishing net and vanished up into the cave. The edges of the hole formed into labia and a small clitoris grew between them. Then his dark bushy pubic hair grew longer, and the changes were complete.
"What does that feel like, Mr Walker?" Sarah asked, mockingly. "You can touch it, if you like."
"I-I-Impossible!!" Stuart gasped. Her fingers touched the lips of her new vagina and pulled back in surprise. "I-It's... really me! It's r-r-real!"
"And that's only the start," Karyn said. "I wish you were totally horny for men and only men, and the longer you spend around any guy, the more and more you'll want him to fuck you!"
"NO!! No!" Stuart protested, but slowly felt the wish coming true. He started to think about cocks, wondering how they would feel in his pussy, long and hard... "...No," he added in quiet desperation, "I don't want this."
"You evil cunt!" Karyn screeched. "How could you do this to my father?? You... you monster!!"
"Oh dear," Sarah looked back at Karyn calmly. "I'm sorry Mr Walker, but Karyn's outburst means I must do something even nastier to you now."
"NO!!" Karyn screamed, but Sarah wasn't looking for that kind of response.
Turning to her latest victim, Sarah made a wish without a second of thought, "I wish you hated being female and wanted to be male more than anything else in the world. But I also wish that each time a guy cums in you - or ON you - your body will become slightly more feminine. Starting with your ass and hips, then your legs and waist, then your feet and arms and then your voice and face. I wish you'll always have that ridiculous receding hairline, but that your boobs will always grow bigger after sex."
"W-What...?" Stuart, who was going into shock and fast, could barely say a word.
Sarah, noticing the defiant look in Karyn's eyes, added, "Finally, I wish for all your periods to have an outrageously heavy flow, and be accompanied by incredibly painful menstrual cramps!"
"Stop it! Please!!" Karyn pleaded, streams of tears rolling down her face.
At last, the bitch is crying, Sarah thought smugly. "Okay Mr Walker, you go upstairs and masturbate for the next, hmmm, six hours. I want you to get to know yourself better. Oh, and I wish you had a stack of porn mags in your bedroom devoted to big, fat cocks!"
Solemnly, Stuart climbed the stairs and went to his bedroom. He didn't even bother to get dressed or even pick up his clothes first. Karyn gawped at the huge smile on her tormentor's face.
"You know, this is turning out to be a really good day," Sarah said, and laughed callously.
