"Well", Emily said, "I did have an idea"
"Let's hear it"
The two of them sat on the couch, with the mystery box between them, its mahogany finish shining in the evening light. Zoe sat there, watching Emily with interest.
"Well why not whatever form we use from the box tonight is what we'll stay with for the evening?" Emily suggested.
Zoe looked at Emily suspiciously, "You're going to do it again, aren't you?"
Emily looked on in mock shock, "No! Once was enough", she replied, "But it was fun though, you have to admit"
Zoe nodded reluctantly, the little incident they were referring to involved Emily replacing Zoe's nose, eyes, mouth, nipples, belly button, anus and ears with vaginas, she was blind, deaf and mute to the world for the hours that she was like that. Zoe enjoyed it and even though she trusted Emily, she was terrified at not being able to do, hear or see anything.
"Besides", Emily said, snapping Zoe out of her thoughts, "This time you'll be in charge"
"Oh really?" Zoe said.
"Yup", Emily replied, "here we go, I hope this works"
Emily focused on the box, she concentrated for a moment and then opened it, inside the box was a big bundle of skin coloured fabric, as she pulled it out, Zoe had a feel for the fabric, it felt like a thing rubber/elastic material, but since it was scrunched up, she couldn't tell what exactly it was.
Emily grabbed the scrunched up fabric and pulled it free of the box, as she lifted it over the lounge, Emily stood up and headed back into the more open area of the bedroom, she called back to Zoe over her shoulder, "Lose your little guy Zoe, you won't need him"
Zoe complied, extracting her penis and putting it back into the box. It felt unusual to have a void between her legs again; she'd had the penis on so often it felt natural to her. Zoe got up and followed Emily back into the bedroom. She found Emily had stretched the fabric out, it seemed to be a sort of latex fetish suit, like the ones that some people bought for "erotic" cosplay, but Zoe couldn't figure out exactly what it was supposed to be, shape wise.
Emily kneeled on the floor, untangling the suit, stretching it all out, there were four limbs in the suit, between the front limbs of the suit was a head-sized hole, but strangely enough, there was another hole on what Zoe could only assume was the back of the suit, almost perpendicular to the head hole, Zoe wondered what that was for. When Emily finished, she stood up and looked at Zoe.
"Ok, do you promise we'll go to Jon and Karyn's if we use this?" Emily asked, "You won't try to change back?"
Zoe knew she was in for trouble, whenever they used the box and Emily said that, it always meant something very strange was in store for her, "Ok", Zoe said, hoping the nervousness was not creeping into her voice, "What do we do?"
"Get naked first", Emily said, stripping off her clothes, throwing them on the bed.
While Zoe was doing the same, Emily crawled over to the front of the costume grabbed the large empty hole on it's back, she climbed in, one foot after the other, sliding them easily into the cold latex suit, lining her legs up perfectly with suit's legs. Emily pulled the entire suit up over her head and fumbled about in the stretchy fabric. Zoe could see Emily had bundled back up against the rear of the costume, she could make out that Emily was crouched against the legs.
"Ok Zoe", Emily's muffled voice called out, "Get on in"
"Um, how?" Zoe asked.
"Same way I did", Emily's muffled voice replied.
So looked at the suit rather hesitantly, she picked up the front half of the costume and stretched the hole Emily climbed into, easily raising her feet over the lip of the latex, she climbed inside the suit. Zoe tried to copy Emily and pushed her legs towards the rear of the costume. Emily yelped in surprise as a foot hit her in the face.
"Ow! Z, not back here, I'm here", Emily called out.
"Then where?" Zoe asked, half in the costume and very confused.
"The front of course, silly girl!" Emily replied.
Zoe looked at the costume, she found the front limbs were still discarded, and now that she looked down at them, they resembled feet, rather then hands. Zoe had a sneaking suspicious what they were going to end up doing. She fed her legs through sleeves of the costume and down to the ground, her feet completely enclosed in the latex. Zoe found that she couldn't fit her entire body in the front part of the costume though, from the waist up, she stuck out the large hole in the back of the costume, which had now snapped back into place, tightly hugging Zoe's hips.
Looking down, Zoe could see the hole she thought would be for the head of the costume was actually empty, and lined up against her crotch. Checking herself out, even with the stretched latex around the two girls, it looked like Zoe and Emily were some sort of freakish hairless pantomime horse. Zoe looked back at the concealed figure in the rear of the costume.
"Emily, I'm in, what now?" Zoe asked.
"Don't move", Emily replied.
Zoe wasn't sure what Emily meant by that, but she saw Emily starting to feed her way through the costume towards Zoe. Zoe yelped as Emily's hands slid down the front legs and wrapped themselves around her own legs. Emily's hands were cold, but Zoe did as she was told and didn't move. However, it became very difficult not to when Emily forced her way under Zoe's legs. Her brown hair tickling Zoe's unprotected vagina.
"Ohhh!" Zoe moaned.
Emily poked her head through the small hole in the front of the costume, the costume was actually pulling Emily's head upwards since she had already pulled it down from it's position in front of Zoe's crotch to fit her head, forcing Emily's head to brush against Zoe's crotch as the elastic tried to snap back into place.
"Eagh!" Emily cried out as she poked her head through, "Fresh air again"
The two women stood there in the costume, it was rather amusing to see, from the look of it, it seemed like Emily was giving a piggy-back ride to Zoe, who happened to be perched on Emily's neck, rather then back.
Nothing else seemed to be happening, normally when one of the box's toys were applied to either of the girls, it started transforming into the corresponding "real" body part, but this costume didn't seem to be doing anything of the sort. It was still a fake piece of latex.
"Lee, why isn't this working?" Zoe asked curiously.
"I don't know", Emily replied.
Zoe was overwhelmed by the feeling she received from her crotch when Emily spoke, it was like her voice was coming from INSIDE Zoe's vagina. Zoe looked down and couldn't see anything different wait, yes she could. Emily's head wasn't stretching the latex downwards anymore, but it was poking through the hole that was previously at Zoe's crotch level. Looking further down, Zoe could see that the legs of the costume at the front were no longer bulky, containing both Zoe's legs and Emily's arms, they looked thinner, thicker then Zoe's legs did but not as thick as if two limbs were sharing the same sleeve.
"Oh my god, it's working", Zoe exclaimed, as she watched.
The front legs of the costume continued to shrink, until all that was left was a single pair of female legs, Zoe's. The latex shine seemed to be fading away from the skin as she watched, revealing real skin underneath. Zoe looked behind her and could see that the shine was fading away from the skin behind her too. The skin took on a slightly darker tone at the same time, seemingly matching Emily's flesh tones, leading all the way up until it reached the hip where the lip of the suit met Zoe's waist, then it transitioned into Zoe's skin tone.
"Zoe, I feel strange", Emily said, the vibrating feeling was MUCH more pronounced now; it felt like Zoe's pussy was actually speaking.
Reaching down and touching Emily's head, she could feel her hands on her own crotch; it was like Emily's head had become an extension of her own vagina. She explored further down with her hand and found that Emily's neck extended out from exactly where her vagina used to be.
"Wow Ly", Zoe commented, "You have some really strange ideas", as she looked herself over.
Zoe tried to reposition herself so that she could examine herself better and found that she control both pairs of legs.
"Hey!" Emily said softly, as to try and avoid arousing Zoe, "I can feel my legs moving, but I can't move them myself"
"I guess I control your legs as well as mine", Zoe said, with a bit of effort she figured out how to coordinate her four limbs.
Zoe walked slowly over to the large standing mirror in Emily's bedroom. Reflected in the mirror were the two girls in their new form. Essentially it was very basic centaur-like shape with Emily's body providing the "rear" barrel section. Starting from the top, Zoe above the waist looked completely normal, nothing had changed. However, when looking down at the waist, Emily's head had now replaced Zoe's crotch, but further down, it still looked like Zoe's regular legs, except they now reflected Emily's skin tone.
Zoe couldn't get a good view of the rest of their new body, so she had to stand angled on in the mirror. She could feel a few things on the new body that she could recognize but wasn't sure where they were. After standing side on, and much to Emily's protests, she could examine the rest of her body. Emily's entire body now seemed to be pretty much a duplicate of Zoe's in shape, the proportions for Emily's body was now identical to Zoe's.
Zoe could see that Emily's breasts were still on her body, now just behind Zoe's front legs and dangling down towards the floor. Further back, the two of them had another "real" vagina nestled between their rear legs, unfortunately it seems like it was a little exposed, much as women usually were when they bent over. With a little bit of stretching, Zoe was able to just reach her new ass's position on their rear legs, she could feel her hand touching the strange extension of her body as she gently slid her hand along her new lengthened ass back to her hips.
"This is really turning you on Zoe, isn't it?" Emily asked coyly.
"Why do you ask?" Zoe responded.
"Because", Emily gulped, "I'm drooling and it's got a sure strange taste to it"
Zoe realized that since Emily was filling in for her old vagina, that meant that Emily would obviously feel the arousal in her mouth, including being able to cum like a real vagina.
"So what do you think?" Emily asked, "Worth it?"
Zoe laughed, "It's definitely one of the more unique ideas you've ever had. I just hope we can get out of it later"
"Well, if worse comes to worse, we can always ask Jon for help", Emily replied.
"True enough", Zoe agreed, she looked herself over in the mirror again, "So what do you want to do?"
Emily licked her lips, sending a shudder up their combined bodies, "Well. I do have one thought", she said seductively.
"Oh?" Zoe replied with a grin, she knew what Emily had in mind.
"Well", Emily said, "How long have we got before we need to leave for Jon's?"
Zoe checked the alarm clock next to Emily's bead, "A few hours"
"Then ", Emily replied, drawing out the sound, making her mouth quiver from the vibrations she produced, "I suppose we could take the time to explore ourselves a bit"
Zoe was already starting to be overwhelmed by the new feelings in her body, all four of their breasts were starting to throb, demanding attention, and unfortunately Zoe only had two hands. Both their vaginas, Emily's mouth and their "real" one were also aching from building anticipation. Zoe started to rub her left breast "“ her normal one, while sticking two fingers of her free hand into Emily's waiting mouth.
