Kat waved her wand and cast a spell on Sandy. Immediately, she began to feel tingly.
Kat, that is. Sandy was fine.
Kat's fingers felt odd. Kat then noticed a gold chain around Sandy's neck.
"What's that around your neck?" she said, beginning to get quieter as she lost her voice.
"This?" Sandy pulled the necklace out from under her shirt. It's emblem was a simple golden circle with a red and gold asterisk over a green background, "My grandma gave me this for my birthday last year, why?"
Kat recognized it instantly. She was wearing a reversal rune; it protected her from any physical change or damage from spells. She felt her blood run cold, both from shock and fear. Looking at her hands, she felt as if they weren't her own. Then, everything went dark.
When she awoke, she could only see darkness. Where was she? How long was she out? Why was where she was so warm and comfy? Trying to get up, she found herself barely able to move, only being able to move her face muscles.
Suddenly, everything got a lot brighter. Squinting through a layer of cloth, she made out the shape of a head. Her vision got clearer as it was removed. In front of her was Dan, dressed in her clothes. Behind him was her bedroom, but everything was higher than she remembered.
The conclusion hit her like a truck. She'd become Sandy's vagina. Attempting to cast another spell, all she managed to do was twitch and splutter. A moan from her m-, Sandy came from above her.
"Is she okay?" she asked, genuinely concerned Kat may have gotten hurt by her spell.
"She seems fine," said Dan. Kat continued to twitch and spaz, trying to get the spell to work, "she seems a bit angry that she's your vagina now, though."
"I think I know exactly how to fix that," she said, biting her lip, "and pay her back for transforming you."
The two locked eyes. Dan retreated to Kat's bed, the skirt flapping up to reveal his admittedly small length, which grew larger by the second.
Sandy walked up to the bed, leaning forward to put her elbows on the covers to watch Dan undress. Kat had a full view of the floor and her m-, Sandy's inner thighs. On her left thigh was a tattoo; it had the same asterisk from the reversal symbol, but it was in a black square. Over the asterisk, touching each side of the box, was a blue circle. That was a magical redirection rune. Any curse, hex, or spell cast onto a person with that symbol would either absorb the magic or spit it away. It could only be beaten by spells cast from reversal runes or by removing it from the person.
Sandy got up and removed her shirt before stepping onto the bed. Dan's penis was 8 inches long and was slick from Sandy's saliva.
Kat gaped and quivered from awe and fear.
"I can see she likes what she sees," said Dan, gripping it.
"We'll see how much she likes it inside her," Sandy said positioning herself above it.
Without warning, Sandy dropped onto it.
