"Fuck it." They both said as they both reached for the stone.
"Okay, how does this thing work?" Sarah asked as they held hands with the stone in between.
"We need to make the wish where nobody can hear us except each other in order for the reality warping thing to work." Karyn explained. "So, bathroom?"
"I think we'll get more privacy in a changing room." Sarah said. The two of them got up and held hands as they rushed over to the nearest clothing store they could find. This was actually happening and they wanted to make it happen ASAP.
Finding a clothing store in the mall, the two of them briefly went their separate ways to grab some clothes to try on so they could use the changing rooms. Sarah found a dress while Karyn grabbed a pair of jeans. With clothes in hand, the two of them hurried over to the changing stalls and were allowed in. Like Sarah had thought, the rooms were spaced out more than the bathroom stalls and less people could hear them. They were ready to make the wish.
"Which side do you want to be on?" Karyn asked, holding up the stone.
"I guess I'll take lefties." Sarah said as she held her hand. The two of them felt like their hearts were going to explode any second.
"Okay... I wish that Sarah and I were stuck together as a single person with two heads. She's the left head and controls the left side of the body, and I'm the right head and control the right half of the body, but we feel everything on our torso." Karyn wished. The stone glowed and with a flash of light, the two of them were pulled together into a single body. The two of them gasped as they felt themselves lose control of each other's limbs.
In stunned silence the two of them wobbled a bit as they tried to get used to having one leg each. They had to gently turn themselves in order to see themselves in the mirror, and it was everything they could have imagined. "Holy shit..." They stammered out. In awe, Sarah brought her hand up to their stomach, now covered in a strange merging of their clothes, and rubbed it to see if it was real. She found no seam. Nothing to indicate they were two separate people. And since the stone couldn't reverse wishes, they were well and truly stuck together. The thought was enough to get the girls leaking down below. "Oh, FUCK!!..." They said as quietly as they could as to not start a commotion.
"Oh, God. This is it!" Sarah said, her excitement getting the better of her as she leaned them to the side.
"It is! We're stuck!" Karyn added, pulling back on her. Neither of the girls were particularly in love or anything, but they couldn't resist planting their lips on each other and starting to make out from how horny they were getting. After a few minutes of sucking face, Karyn broke off. "C-come on... We should probably get to one of our houses before we start leaking all over the floor here..." She panted.
"Good idea..." Sarah said. Before they got anywhere though, Sarah stopped them. "Wait, wait, wait!"
"What?"
Holding up the stone in their hands, Sarah prepared to make a wish. "I wish that everyone thought we were super sexy and sharing a body made us even sexier."
"Wait-!" Karyn tried to say before she finished, but it was too late. Another flash happened and the wish was granted. "Sarah! I'm not looking to be a piece of eye candy!"
"What? Don't you want to be able to go out proudly and embrace how hot we are like this?" Sarah argued.
"Not while being drooled at! That's what I have you for!" Karyn explained. "We need to do something to change this wish..." She started as she tried to pull the stone to her side.
"Hey! I want everyone to see how hot we are!" Sarah said as she pulled the stone back towards her. After a few seconds of grunting and pulling the stone back and forth, the two headed woman looked at each other with serious looks in their eyes...
