Joey woke up slowly, in a daze. Ugh. There was a horrible taste in his mouth, the bed was trashed, and the scent of sex was strong in the air. Sitting up, he realized something was very wrong.
First, he had breasts. His arms and hands looked very feminine as well. However, just below his belly button, rather than the hips and thighs he expected, his...her...body...was no longer his body. Instead he was conjoined to another girl. She was in a partly seated position, as his body ended right where her thighs would be, thus, she had a waist. She had no legs, but she had six arms, the lowest of which looked like the arms of a little girl. There was a little girl's pussy where her belly button would be, and just below her breasts, was the face of a little girl, her eyes closed. A pair of impressive breasts, and a woman's head above them. He saw female legs splayed out behind her, as if they were projecting from her back. Even though he didn't seem to have a pussy, he felt...some part of his twisted form...had to go to the bathroom.
The eyes of the little girl opened, and her mouth formed a tiny 'o' of shock. "What...oh...fuck..." The lowest set of arms moved, and she gestured to what she could see.
Then the woman's eyes opened. "I haven't ever been fucked like that...um...holy shit." Her eyes widened in a mix of awe, revulsion, fear, and lust as she gazed upon their horribly mutated body.
"I agree!" The child said. "Um, I can't seem to turn my head."
"That's because you don't have a neck." Joey supplied.
"Wait..." the woman looked down. "If I'm Melissa, who are...?"
"Missy, duh. And that pretty piece of fluff we're merged with has to be girl-type Joey."
"Wish boy...I know what I said, but...fuck!" Melissa spread her arms wide (all four of them she controlled).
"I can undo this..." Joey tried not to sound panicked.
"Good because we have to pee. From somewhere." Missy frowned at him.
"Ok, um, oh Jesus, do I wish us back to normal? What is normal for us? And how can you be Melissa and Missy? Did I split you apart, is one of you a clone, an alternate universe version..." Ok, he was panicked now.
"Joseph. Wish Missy was no longer merged with us, and that she's the one who has to use the bathroom." Melissa ordered.
"Why me, I have the smallest bladder!" Missy whined. "I don't want to wet the bed, I'm not a baby!"
"Oh for fuck's sake, give her my pussy then. Wherever it is."
Joey fumbled for a moment, then made the wish. There was a flash of light, and Missy was standing next to the bed. Joey/Melissa no longer had little girl arms, and he could no longer see the legs behind Melissa's torso. Missy looked rather ridiculous, as she was basically a six year old girl from the waist up, and an adult woman from the waist down, her tiny waist flaring into wide hips.
"Oh...jeez...this is hard to balance like this..just a minute." Missy wobbled into the bathroom, a process which made her shapely behind wiggle suggestively.
Joey felt something grow hard, but he didn't know where it was.
"Oh Goddess, is that your cock? Is that what it feels like? Where is it?" Melissa looked around.
"I have no idea!" Joey couldn't see it either, but it was getting rock hard.
"What?! I want to feel a cock! Is it nice?" Missy complained from the bathroom. The sound of urine hitting porcelain could be heard. "Oh that feels much better."
"It's...kind of weird, really. Hey does that mean Joey can feel your pussy?" Melissa reached down and stroked the little girl pussy in her abdomen with her fingertips. "Oh fuck, that's sensitive."
All Joey could do was moan in pleasure, as he reached for his breasts, feeling himself up.
There was the sound of a toilet flushing, and Missy came back out. "Oh that's hot. Twisted, but hot. Fuck, I can't reach your pussy with these short arms!" She flailed about, obviously needing to scratch an itch.
"Joey! You gotta wish us apart!"
Joey gasped, but managed to make a wish between moans. "I wish Melissa and I were two separate people!"
There was a flash of light, and he had legs again. Little girl legs, with a little girl pussy between them.
Meanwhile, kneeling on the bed before him, Melissa stared down in horror at the penis between a pair of shapely legs that didn't belong to her. It was very hard. She reached down to touch it.
"Oh God, it's a part of me. I think...I think I'm going to cum!"
"Put it in me, it won't fit in Joey!" Missy struggled to get on the bed.
Joey helped her up, and held her from behind as she spread her adult legs for Melissa. He kissed Missy's hair, neck, and nibbled on her ears as Melissa none-too-gently thrust her borrowed penis into her.
It ended shortly thereafter, with Melissa gasping for breath, and Missy moaning in a very un-childlike way with pleasure.
"Holy fuck, Joey. What did you do?" Melissa just goggled at the two girls before her.
"You said anything goes. So I merged us together to have a one-way, three-way?" Joey answered, sheepishly.
"You idiot. You split me into two girls!"
"I can merge you back together, no problem." Joey replied.
"Well wait, does one of us cease to exist, then? I don't want to not exist, and I bet Missy doesn't either." Melissa seemed unhappy.
"I...well what should I do?"
