First information was gently inserted into everyone’s mind, information about what would soon occur.
Going forward people between approximately the ages 17 and 23 would undergo a sort of second puberty: they would develop into fully functional hermaphrodites. The majority of people will have this hermaphrodation occur at the later end of the range, 19 to 22, with only about 5% having it occur before 19.
For males this would take the form of developing breasts, loss of chest hair above the bottom of the rib cage, a slight widening of the pelvis and obviously the growth of a second reproductive system, a female one. This process generally takes six months, though breast development may continue sporadically well into one’s 20s.
For females, the main physical changes would be mainly limited to simply developing their male reproductive system, with few or no other visible changes. Development of the male reproductive system generally takes only three to four months for females.
These however are only the most common outcomes, and the tail of possibilities is long. For instance, it is entirely possible for example for a male to end up with an entirely feminine appearance by the end of this second major sexual development period. Or the opposite for some one born female, or anything in between. A person’s desires can have an influence on this, so for example a closeted trans woman is more likely to end up with a feminine appearance than a man. These outliers may take a year or more to fully change into their new appearance. Though the majority of people do follow the rules above.
The last thing that changes is sexual preferences, those attracted to men gain an interest in breasts on men. Everyone gains new urges and reflexes related to their new parts, and mostly gains an interest in the parts they were formally uninterested in. These are again generalisations, other outcomes are possible, rarely some may find their orientation changing, some may become bi, others may go from straight to gay, or the opposite, such cases would be rare.
Everyone ends up with a dual libido, that is, it is possible to be aroused with only one’s male parts, or only one’s female parts. In fact for most people at some point their body will “lock in” to one or the other, releasing a pheromone signal that will cause their partner to “lock in” to the opposite. Once someone locks into female “mode”, their male parts would pull almost entirely into their body to get them out of the way, much the same way they do in the cold.
The change that came was that everyone in the world would be altered as if this had always been the case, so those over 22 would all rapidly change into the hermaphroditic version of themselves, and those between 17 and 22 would land at some level of development of their new characteristics.
The warning given also included information that, at least in this initial change, people’s relationships would be taken into account. So it would mostly avoid leaving those in love unattracted to their partner.
For Jon and Karyn they would both become fully developed hermaphrodites when the change occurred.
Jon was sitting in his first class, it was about halfway through it when the warning about the coming change was inserted into his mind, followed quickly by the information about what it was. He looked around the room, the mood had changed, the teacher had stopped talking. Everyone was a little disoriented by having their heads filled with new data. They all seemed to by trying to ignore it. Jon knew this feeling of information overload, it had happened when Karyn had wished for them to know how the wish for him to have boobs for a week had been granted. It seemed unlikely that Karyn would wish for this, nor could he conceive of how to get around the range limit of the stone… however he was quite sure the information was accurate, and that at least the teacher would soon change, whatever power was bringing it about.
He sat, uneasy with the uncertainty: would he change? If he did, would he end up with huge boobs like he had from Karyn’s temporary wish? The thing that really scared him was the fact that maybe he’d change completely and end up looking like a girl. Would Karyn still want him? It claimed to take relationships into account… but would it for him? The teacher had resumed giving her lesson, though the room was still full of tension, and she was obviously nervous.
Then it happened. Jon felt himself begin to change, a slight pressure in his chest, a pulling sensation in his groin, behind his balls, a strange sensation in his guts. He felt his pants start to tighten around his hips as his pelvis changed shape; they went from a relaxed fit to tight on his butt. At the same time, he could feel the weight of his breasts rapidly increasing, filling out, pulling at his shirt. He watched them grow: it was astonishingly quick. When they finished, the weight and movement felt familiar; he was sure they were nearly the same as the ones he had had for a week. He felt the strange sensation of his new parts between his legs. Looking around the room, he saw he was the only one with any visible change. He knew the teacher must have changed too; she was young for a teacher but still beyond the age by which everyone would be fully hermaphrodated.
The teacher had, quite understandably, stopped her lesson again. Jon watched her try to collect herself. She looked around the room, saw Jon, her eyes went straight to his chest. She quickly looked away.
Jon was a little taken aback by the teacher looking at him that way for a moment, then he remembered how much of a hard time Karyn had the previous week, and he ignored it.
“OK class, I… can confirm that the… uhm thing that we all experienced earlier was… accurate. As you probably noticed Jon’s… changes.” she looked back at him, making a valiant effort to look only at his face—she mostly succeeded. “Jon, are you alright, do you think you need some time to collect yourself?”
Jon thought for a moment, “I’d.. like to go to the bathroom for a moment…”
“Very well, has anyone else… changed in ways that are not so visible and is in need of some time alone?” No one moved.
“Good… then… I... shall continue.”
Jon got up and started walking to the door, he immediately noticed several things as he walked; his hips swayed more than he was used to, and he felt the extra tilt in every step. He could also feel his new parts down below shifting and rubbing slightly against themselves as he walked. He assumed women didn’t notice that because they were used to it, but like when having boobs was new, he felt everything from his new anatomy acutely. The last thing was that, though his boobs didn’t feel too weird to him—he’d only been flat chested again for a day, and the boobs still felt normalish—he was not used to wearing a T-shirt and no bra. He quickly realised he very much wanted a bra. His boobs bounced and jiggled with each step, rubbing slightly on the inside of his shirt.
Jon had his phone in his pocket as he walked to the bathroom. He texted Karyn, asking if she was OK, and had she been affected. He immediately received a response that she had.
When he reached the bathroom, he stood back from the sinks and their mirrors that he could actually see most of his body. His bust was as he expected the same as the last time he had one, his hips were he suddenly knew, wider than typical for post-hermaphrodation men, well into a less curvy woman’s hip shape. Apparently there was more knowledge included by whatever did this than he was consciously aware of. He turned sideways, seeing that his butt was also a bit rounder, it had filled out to maintain its shape with the wider hips, though it did still seem to be just as much muscle as before, so it was very firm when he poked it.
For a moment he considered going into a stall to try to have a look at his new equipment down below… but he quickly remembered that with a shirt on, it was hard to see even his old equipment past his boobs, let alone something that would be behind that from his perspective. Self-examination would have to wait until he could undress and look between his boobs.
He wasn’t at all sure how he felt about his new hips and rounder but; he was worried it might get him made fun of for looking girly… He could probably wish it away, he thought, but should he?
He started walking quickly back to class but was forced to slow down as his unsupported boobs were bouncing uncomfortably.
The rest of the class went as normally as it was possible for it to go, Jon occasionally caught the teacher looking at his chest, but he could tell she was absolutely doing her best not to stare, so he let it slide. Though it did trigger little feelings in his new parts every time he thought about it. He pushed them down and tried to ignore them.
His second class of the day was similar, though there was one other changed male student in that one.
Walking through the halls between classes was an interesting experience. Five percent of guys his age had boobs—that’s 1 in 20, none that he saw as big as his own. Walking the hall he noticed the occasional girl unable to keep her eyes off his braless boobs. He quickly found himself walking with one arm under his bust to cut down on the movement. He now really understood the invention of the bra.
He found the female attention… surprising, though he supposed he shouldn’t; they had been put in a very similar situation to the one Karyn was in the previous week. They weren’t used to liking boobs. Most of them were putting in effort not to stare for too long, not all successfully.
What really caught him off guard was the first time one of the girls noticed his chest and as he approached started standing awkwardly, he couldn’t figure it out for a moment, but as he drew closer he noticed something. A bulge in the front of the skirt the girl was wearing. Then it clicked. She had a boner. This set off something inside him. A new part of him. He felt a small surge of arousal, but not with his male equipment, no, his first taste of his female libido. The physical effect wasn’t much, a slight rush of blood and consequently a little warmth, but it hammered home the fact that he was both male and female now, that he had a female libido, that on his camping trip with Karyn he was likely to see her penis… that he would very likely enjoy seeing it. He tried not to think too hard about that, the idea of Karyn’s penis had also pushed on his new female libidio… It was harder to ignore than his original one, it was new, he wasn’t used to it, so he pushed it down, thought about math.
By the time he reached his physics class he’d managed to calm himself down. He was very surprised to find a girl sitting beside him, where his lab partner Bill should be.
“Uh, hi Jon… I… I’m Bill.”
Jon stared at her… him? He wasn’t sure, the girl could easily be Bill’s sister, she was the same height as him, and at a second look her clothes were obviously not really fitting her properly, a little loose in the shoulders, much too tight across her bust, nearly as big as Jon’s, her hair was cut the way Bill’s was… Bill had been one of the rare people who ended up with a drastic change, all the way to feminine appearance.
“I… see” Jon said, “I… are you OK? I mean this” he gestured down to his chest, “is a lot to get used to… and the uh other things, but well I… can’t imagine being in your position…”
“Yeah… I’m… well I can… cope.”
“Are you sure… I… I mean they’d probably let you go home…”
“Yeah, I’m sure…”
Something pricked at the back of Jon’s mind, Bill wasn’t single. “OH! Err…”
“What?”
“I just… well your boyfriend…”
“Uh yeah… We share a first class, the teacher let us both step out of the room for a minute… turns out he… um well what he likes changed… we’re OK… at least as much as one could expect.”
“Oh. I… well if you need to talk I’m… willing to listen.”
“Thanks, I… well I mean we have at least one new problem in common.” Bill glanced down at Jon’s chest.
“Err, yeah, I… think I’m going to be getting a bra ASAP…”
“Yeah… I… God the looks I got while walking here, people seem to just assume I’m… a girl and I… didn’t wear one on purpose…”, he sighed, “I… I’m sorry if I look, I’m not used… to… liking er…”
“I understand, don’t worry too much about it, just uh try not to stare. My homeroom teacher had the same problem. It was kinda funny seeing her avoid looking at me as much as she could. I… so you… still… uhm…”
“Could you try your best to think of me as a guy still? At least for now… this is a lot to process.”
“Uh, shure…”
The physics teacher walked in, putting an end to their conversation. He too had boobs, not very big, but they were very obvious under his shirt, and like every other man over 23 he hadn’t had any chance to do anything to support them yet, so he was obviously trying to ignore them.
The rest of the morning passed similarly for Jon, the occasional girl finding his chest distracting in ways she wasn’t used to and being unable to stop herself from looking, sometimes staring. He did his best to ignore it, though part of him enjoyed it; it made him feel attractive, but it also made him feel things he wasn’t used to in his new vagina, little spikes of arousal. He did his best to ignore the new sensations; he wasn’t prepared to deal with those feelings in school. One thing he very much noticed that was different from the last time he was at school with boobs was how other guys who didn’t have any reacted. They didn’t make fun of him. Was it because they knew he was an early bloomer and they’d be getting boobs themselves soon enough? Was it just that they were overwhelmed by the strangeness of the change to the world? Jon didn’t know. Either way it did make the experience much less unpleasant.
At lunch time, he, much as he had the previous week, planned on grabbing something and eating while sitting alone on the wall, but while he was getting something from the cafeteria he saw Biff.
What surprised him was that Biff looked exactly as he had during the previous week, his shirt very tight across his bust, big, dome shaped boobs stretching it out. He saw Sarah with him, very obviously distracted by Biff's new bust. Sarah looked very similar, perhaps a bit more muscled, Jon looked her up and down, it was also obvious that she was hiding an erection, holding her purse tight against her crotch. It was obvious the two of them were feeling new things and they were both uncomfortable with them.
Jon for his part didn’t want to think about Sarah having a hard-on for fear of turning on his own new libido so he quickly turned away.
Once he reached the wall and started eating, alone with his thoughts, he found that, more than at any other time during the semester, he wished he shared a lunch period with Karyn. He wanted to talk to her, work out problems with her, find solutions, and just to vent. To vent about how weird walking felt with his new hips, the way they forced him to let them sway a little more, not a lot, not enough to make his walk obviously feminie, just enough to feel strange. They were wide, wider than some girls’ hips. He felt weird about that. The extra thickness of his butt, now that he was aware of it, he couldn’t stop feeling it whenever he sat down, even now sitting on the wall, he could feel the little extra bit of muscle underneath him. Most of all he wanted to know that the change had taken his relationship with Karyn into account and that she was still attracted to him.
Near the end of his lunch period Jon started walking to his next class, very glad that it wasn’t a Gym day for him, he wouldn’t want to do that without a bra for anything. He tucked his left arm under his breasts to hold them up and cut down on bouncing. They were already a bit sore from just the walking he had done in the morning without support.
The next class was civics, and today involved a discussion time towards the end. Half the class had been assigned different readings the previous week and now they had to explain their part to the other person. Jon was paired up with a girl, she had changed too. The problem was she spent much of the discussion period talking to Jon’s chest. He tried to be understanding, to let it slide, but she wasn’t getting better as it went on… she didn’t even seem to be trying too hard. Eventually Jon said something.
“Hey, uh… I’m up here.”
She turned bright red. “I… oh… I’m sorry… I… I’m just not… it’s… new…”
“I... look I know, they’re big, and… I’m a guy… I get… the uhm difficulty… and I know you’re not used to it… but please try not to… that is.. try to talk to me and not… them.”
“I… I’m so sorry, I’ll do better.”
They went back to their discussion, she did do better, still looking frequently, but no longer just staring. Jon could deal with that. As long as she was obviously trying not to stare he could let it slide, for now.
Walking through the hall to his next class it was getting easy to pick out the girls that had changed, they all walked or stood a little strangely, Jon guessed because they weren’t used to the new equipment, though he tried not to think about that, he really wasn’t quite ready to feel arousal in his new parts. It was bad enough that he was constantly aware of the presence of that new anatomy, especially while walking, he needed to process it.
Math class passed uneventfully, he seemed to be the only one changed other than the teacher in the class.
At the end of the day he rushed to the wall as fast as he could, given the limitations of having to hold his boobs, to meet Karyn at the wall. Today was different, slowed down by not having a bra. Karyn had arrived first, waiting for him, but as he approached she stood and gave him an energetic embrace.
The change began, Karyn felt it, her panties rapidly filled, then overfilled. Her new balls didn’t fit in the small area of fabric at the front. She found herself squirming uncomfortably. Looking up she noticed the teacher’s new boobs, quashed her desire to look more at them, glad she had practice dealing with being into boobs, and raised her hand.
The teacher had stopped speaking in surprise as the change hit him. He stood for a moment, then came back to reality and looked around the room.
“Ah… Karyn, yes?”
“May I go to the washroom?”
“Err, yes go ahead.”
She left, walking awkwardly, feeling her panties shift, her new balls ended up out one side and her penis out the other leg hole, it was not comfortable.
As she walked she received Jon’s text and responded as she walked.
On arriving at the bathroom she went into one of the stalls and pulled down her pants and underwear and sat down. Leaning forward so she could see past her breasts, she spread her legs, forcing her panties all the way down, she looked at her new parts. It looked… as she expected from seeing Jon’s when flaccid. It looked about the same size as his.
For a few minutes she sat staring at herself and thinking, what to do about her underwear situation. Her pants had ample room as they were slightly oversized slacks. She eventually decided to simply take her panties off.
She stepped out of the stall, her panties placed in a pocket on the slacks. She felt her new parts moving around as she walked, she now knew exactly what Jon meant when he talked about being constantly aware of his boobs, the newness of the sensations stopped her from being able to ignore them. She stopped, looking at herself in the mirror over one of the sinks on the wall opposite the stalls. She looked herself up and down, seeing the slight bulge in the front of her pants. It made her feel… odd. Knowing that she had a penis, that she could see the result of having it, that everyone would be able to see.
She looked for a few minutes, changing how she stood several times, there was no getting away from it, the bulge, though subtle, was always there. She did a little jump and felt things moving around… there wasn’t much visible motion, but she very much felt it.
She briefly wondered if she would be able to get out of the rest of the day. Then she thought about how her parents would react. They had to live the entire day as if it were normal, she could do it too.
Another look in the mirror. Jon had changed too. What did he look like? Were his boobs as big… the thought brought the image of busty Jon to mind, she felt her new parts respond, alongside her original ones, just a little. Slight stiffening, not an actual erection, but it was visible in the front of her pants. She banished the thought from her mind. She did not want to be walking around pitching a tent.
She waited, looking at herself. The semi pushing against the front of her pants unrestricted by underwear, it was just stiff enough to lift the fabric a bit and make itself more obvious. It felt very strange to Karyn. Seeing it. Feeling it. The sensations were a little familiar. A little like what she felt in her clit.. but bigger and a bit… more. It made her wonder what it was going to feel like to have a full hard-on… but she did not want to find that out here and now. She ran through some chemistry in her head, pulling organic chemical names out of her memory and visualising their shapes.
After another few minutes she no longer felt her new part pushing against her fly, so she started walking back to class, upon arriving she looked around as she entered, she was glad she was the only student in the class who had changed. Particularly that there were no guys that had changed. She really didn’t want to try to hide a boner.
The rest of the class she focused on the lesson far far more than she had at any time in the past week, more than she had in a long time. Though she avoided looking at the teacher.
She was dreading the walk to her next class. She knew from experience that there were a few girls with nice enough boobs to make her feel things, despite the fact that she wasn’t into girls… She found that the week of practice helped a lot, especially now that she was trying harder not to let herself look. She was constantly aware of her new parts, the way they moved as she walked, the slight rubbing against the fabric of her slacks. It wasn’t helping her state of mind.
Her second class presented a problem, not only did she have a seat next to a very busty girl, but on the other side of her sat a guy who had changed, and he too had a very nice set of boobs. They weren’t huge, but they were enough that when he walked in front of her to get to his desk, unsupported boobs bouncing around in his shirt, she felt that response again. Just a slight bit of extra blood flow and a little stiffness, she felt it in her original parts too, but her new one was far more distracting. The novelty made it much harder to ignore. Thankfully she didn’t need to move at any point during class, but she spent a lot of it staring at her notes.
She decided to skip lunch entirely, not willing to risk the cafeteria at all. She even hopped over the wall and sat there, looking at an empty lot. She did find herself wondering what it would feel like when she did let it happen. How would her penis look? Jon’s had been bigger than she expected, though she had no real sense of what counted as ‘big’ or ‘small’... What would hers be like?
The way she was sitting put pressure on that area; it felt strange. The fabric of her slacks pulled against her new balls and her penis. She couldn’t see anything past her boobs, and couldn’t move so she could without completely changing her position.
She resolved that she had to know once she got some time alone that night.
As she sat she realised she needed to use the bathroom. She stood and headed into the school, as she walked she had a little debate with herself. Should she attempt to pee standing up? What if she missed? She walked into the bathroom and into a stall. She found a bit of a mess. She wasn’t the only girl in the school who had changed. One of the others apparently did try standing and found it more difficult than expected.
Karyn stood looking at the situation for a moment. Her bladder reminded her she was there for an actual need. She decided she couldn’t make the situation much worse and undid the fly on her slacks, fiddled around a bit and pulled her new part out. She couldn’t see what she was doing past her boobs. So she leaned forward a bit and put her off hand on her chest to help hold her boobs close to it and squish them a bit. Eventually she found a position where she could see both herself and the toilet. She pointed it at the toilet and… for a moment she wasn’t sure what to do. She relaxed. That part was the same she felt the flow start. Felt it flow inside her, then it felt different she felt the slight warmth running along inside her new appendage. It shot out. In two directions, she started to panic and leaned over, to get closer hoping to get both streams into the bowl. As she did this they merged into one stream… that was still going off to one side.She adjusted her aim, eventually she got it into the bowl… just in time to start running out of pressure. She continued to adjust her aim, mostly successfully.
After she finished she stood there for a moment unsure of what to do next. Eventually she decided to dab off the tip with a tissue, as she would normally. She did so and tossed it into the toilet. She carefully zipped up her pants after putting herself away.
She would be sitting until she could ask Jon for instructions.
Her afternoon classes passed much like her morning ones, her time in the hallways occasionally seeing an attractive changed guy, and a little arousal, thinking about something else until it went away.
At the end of the day she went to the wall, curious about how Jon looked now. Worried she might find herself getting excited seeing him, particularly if he had the same bust he’d had previously. She was surprised to find that she arrived first. She waited.
Eventually she saw him coming, supporting his breasts with his left arm. He looked amazing, she noticed the widened hips, and his returned bust. She found herself surprised at liking both changes to his figure. She felt that arousal begin again, and almost jumped on him to pull him into a hug and kiss. Though not too tight, she didn’t want to get herself too… excited. The feeling of her boobs squishing against his was still enough to get her going a bit. She felt a little more stretch in her new anatomy, it pushed a little harder on her pants, she wondered, was this a full boner? She wasn’t sure, and with Jon in her arms there was no way to look. She did hold him for a while, trying to get used to doing so. Trying not to think sexy thoughts, or at least doing her best to try to move the feelings over to her old equipment. Eventually she did manage to get herself feeling aroused the way she was more used to.
Jon for his part through the entire embrace felt his female arousal quickly eclipse his male arousal levels. He even for a moment thought he felt her semi-erection touch him… and he felt a rush of wetness. He could even feel that his body was getting close to a “mode shift” into female mode. Something he didn’t know he “knew”. It seemed the change had been a little more helpful than he thought, though knowing he was close to it didn’t help him much with stopping it. Luckily Karyn released him and it helped him calm down.
“Hey Jon-boyfriend, what took you?”
He pointed at his chest with his free hand, “Lack of um support… er… could we head for the mall so I can fix that problem?”
“Uh sure.”
Karyn was thrilled that Jon had his boobs back, she felt very strange about how she felt about his new hip shape and his butt. His butt was nice before, but now it was astounding. He looked better overall to her than before, but still feeling this way about that shape felt strange.
Part of her was hoping to get a little show as he tried on bras… but the other part of her was very not ready to deal with having her first hard on in a public place.
As it turned out she needn't have worried. Much of the bra section had been picked clean, though not as badly as it could have been since most adults hadn’t had a chance to get there yet, still being at work, and only about 1 in 20 high school students had changed. Though even if the place had still been fully stocked they didn’t carry bras in Jon’s cup size, they only went up to DD. Apparently Jon would need to either order from a specialty store online or find one in town.
All they managed to find that would fit him at all was a sports bra, and that wasn’t a very good fit.
Karyn did pick up some men’s briefs that seemed like they might fit well enough to give her something to wear for the next week.
Jon slipped into a fitting room to put on his new bra after they both checked out.
As they walked they chatted a bit about the change.
“Hey, Jon-boyfriend? How do you feel about… well having boobs permanently?”
“I… hmm.” He thought for a moment, “I… well I guess I’m not… opposed to it… well I know how much you liked them, it was pretty obvious. After today… I kinda feel good about them, despite the… discomfort, the way a lot of girls were looking at them… felt weird, but also… good? I dunno I’ve never seen a girl do a double take looking at me before and that happened twice today.”
“Double takes? Really? They are very nice boobs. I can’t say I don’t understand reacting that way. Though… I think I’m… used to liking boobs enough that I could probably… stop myself from being so obvious.”
“You think so? Even if I found something that showed lots of cleavage?”
“Cleavage is cheating.” She paused for a few seconds, “I have to admit, I’m… actually very happy your boobs are back… though… this isn’t really how I’d have wanted it to happen.”
“Yeah, I thought you might be.”
“Also… I… well it seemed unfair that… most people who had boobs… didn’t… like them… that way… I’m kinda glad that’s… changed.”
“Uh, huh.”
They were both quiet for a little while.
“Hey, uh Jon-boyfriend? How do you… um deal if… you get… um, that is if…”
“Hard at an… inopportune time?” Jon felt a little thrill of wetness, just at the thought of Karyn having a dick… and needing to hide…
“Yeah… that.”
“I… generally um adjust it to sit in the waistband of my underwear… or pants depending on uh… how full the…”
“Ah.”
“Makes it… less noticeable since it’s against your body.”
“How… do you adjust… without…”
“I dunno… quickly when you think no-one’s looking… I don’t know how successful that is…”
Karyn thought for a moment. “AH! I… that’s… well I guess… how often did that happen around me?”
“Err… now that I think about it… a fair bit.”
“Hah! I thought guys just always wanted to touch themselves.”
Jon turned red.
“No problem Jon-boyfriend, I feel… complimented… now.”
“Got any questions for me about…”
“Uh… not yet… but I’m sure I’ll have some.”
“Well, ask anything… I’ll help in any way I can.” She paused for several seconds agian “Err… this weekend I… uh could use some… instruction on how to… um go standing.”
Jon giggled.
“HEY!”
“I’m not laughing at you… it’s just… well it’s a funny question… did you make a mess in a school bathroom?”
“I… It was a mess when I got there.”
“Ah.”
When they arrived at Jon’s house, Jon's mother was full of awkward questions, and tried to insist on taking him out to shop for bras… until he explained they’d just come from doing that and come up almost empty-handed on ones that fit.
As they left and headed for Jon’s bedroom they heard her muttering about having no clue where those had come from.
They decided to get their homework done. Sitting back to back on Jon’s bed, as had become their habit. Eventually Karyn headed home for dinner. Neither of them felt up to doing any sort of making out just yet, they both felt a need to… at least partially get to know themselves alone.
That evening, alone in her room Karyn was thinking about her new parts. She had her pants pulled down and her shirt off.
She was laying on her back, looking between her boobs at her dick. She touched it, poked her balls, held them. Gently squeezed one, then a little harder, quite suddenly it went from pressure to a lot of pain. Note to self, guys are not exaggerating how sensitive those are. She thought.
She started gently playing with her member. She felt the rush of blood, the warm feeling as it started to stiffen. She found herself thinking about Jon. His boobs. She used her other hand to start playing with one of her own boobs.
Her member started to grow, she watched. It slowly thickened, she could feel the slight pressure inside it, her skin stretching slightly. It slowly inflated itself, she watched it go up to what she thought was Jon’s size and keep going. She felt the skin on it stretch more. She imagined Jon was playing with it with his hands. That he was naked, that she could see him on his hands and knees above her, his boobs dangling from his chest, visible behind her growing penis. She saw it get noticeably larger than Jon’s felt the warm pressure inside it. Her arousal continued to increase. Her amazement at the size of the thing sticking out of her grew along with it. When it stopped she felt it continue to increase in pressure, it felt taught, hard in her hand. It was almost painful itself.
She felt the “mode shift” happen, her vagina dropped off her awareness, all her accustomed sexaul instincts disappeared. Subsumed under her new male ones. She felt all of her sexual arousal focus down into her dick. She felt a building pressure inside her. A need.
It looked absurdly huge to her on her body. She stood, feeling it bounce around as she stepped and turned to look at herself in a mirror. It was definitely substantially bigger than Jon’s. Jon’s would look big on her. This looked massive. It felt so thick in her hand, it felt… thicker than a toilet paper tube. Pointing it up it reached past her bellybutton. She didn’t know it but she was well into the 99th percentile of both length and girth.
“Wow… I… damn. I’m so glad I didn’t get a hard on at school… I… don’t think.. Jon’s suggestion would work for me… especially not if I have to sit down…”
Jon… In her mind she pulled him into a kiss again, felt her erection between his legs, as she moved her hips somewhere in the middle it touched his… new part. She felt warm wetness in her mind. She pulled the imaginary Jon along with her, back into the bed. She layed back. The imaginary Jon straddled her. Her hand went down to her shaft. The imaginary Jon grabbed it and helped guide it to his vagina. She imagined him moaning as it pushed against his entrance. She imagined him lowering himself, pushing her length into him. She started to stroke.
The imaginary Jon was bouncing up and down his boobs jiggling wildly. She was steadily stroking. She found it much easier to remain quiet. Her breathing was quickening, the new feeling of pressure inside her building, a growing need to release that pressure. The imaginary Jon moaned.
She was getting close, she was panting with the exertion. The pressure built and build. Then she felt a pulse, a twitch. A surge as cum ran up inside her dick, a warm wave travelling along it. A second pulse before the first even finished. Semen shot out of her. She grunted. A third pulse. The pressure was releasing. A fourth pulse. A second shot.
She felt herself relax. She was done. It was so strange. She was done. She looked down at the mess she made. She felt her penis slowly start to soften.
It was alien. She had been at the height of arousal, then she came, it felt amazing, unlike anything she had felt before, but when it ended she was done. She was down. The arousal was gone. Things still felt good. Her dick still felt… very nice as it was releasing all the blood it had commandeered from the rest of her body, but unlike what she was used to she didn’t feel like she wanted more. It didn’t feel like she could do more. The afterglow was still there… but all her interest in sexual things was gone. She felt very silly for not planning what to do with… her… load.
It felt strange now, she could tell her body was still very much in male mode. A little bit of info she hadn’t known she knew until she wondered about it told her she was likely to stay in male mode for at least a few hours, potentially even until the morning. It was a strange feeling. Her vagina was there, she she could feel it, but it… didn’t feel like a sexual organ… or even much of anyting, it was a little distant in her awareness, like her toes, not terribly important. She probed it. No stimulation, it just felt like touching skin, except for the location. Her penis however, she was still quite aware of it. Even though she wasn’t turned on. Sensations from it felt vibrant. She felt in the back of her mind, a million little things, reflexes and desires. At the moment she was male. She wasn’t suddenly into women or anything like that, but… Picturing Jon with a hard-on felt weird. Thinking of herself doing… anything with her vagina felt… not quite wrong… but like not… the right thing right now. It was a subtle shift, but it was very much there, and she could feel it.
She had a thought. Would she fit in Jon? Her dick was huge, at least when it was hard, by now it was back to being soft and didn’t look too different from Jon’s.
Jon’s had felt like a lot inside her. Jon was taller than her… but still, the thing between her legs was… very substantial. As she cleaned herself up with kleenex she had on a shelf near her bed left from the last time she’d had a cold, she fretted and worried that she was packing too much for Jon.
Jon was stepping into the shower. The water hit his breasts, he’d almost forgotten how nice that felt. Then he felt something else. Arousal. Female arousal. He let the water wash over him. He was alone now. Might as well just let it happen. He was curious what it felt like, and well he was hoping to make it easier to avoid getting worked up in his female parts tomorrow.
He started to play with his boobs, he felt his new female arousal grow, a little surge of warmth. He imagined Karyn had come up behind him and was feeling him up. His original parts had started to respond too, but the response from his new ones was faster, and stronger.
The part of him that was female conjured up the idea that her erection poked him in the leg. The idea sent a surge of arousal to his female parts. He felt himself moan softly as he started to really imagine Karyn having a penis. He started to get wet. His body was already teetering on the edge of mode switching to female.
He thought about Karyn in front of him… her erection, just at his entrance. And it happened. His body mode switched. He moaned. He could feel all arousal drain from his penis as it rapidly softened and pulled inside him, his balls following. A wave of warm pleasure spread out from them, washing over him. He could feel it, he was in female mode. All his male sexual instincts vanished, no desire to penetrate, the sensations from his male parts felt indestinct, low priority. The idea of a penis on Karyn increased in appeal. A million tiny things, all made him feel physically, undeniably, female.
A stray thought hit his mind… what would it be like in his mouth… arousal. He pushed that away. That was too far for him right now. Feeling into a hard Karyn was one thing… but that was another. He couldn’t deny that part of him was into it now… but he could ignore it.
He let himself sit down in the tub. He continued to play with his boobs. He found himself moaning softly more and more. He had done so last time with Karyn… but this felt different. These were getting harder to hold back.
He imagined Karyn with him, imagined she was the one feeling him up. He let one hand move down. Between his legs, he spread them. He imagined this too was Karyn. He hand slid over where his male parts had gone, nothing, it felt much like touching his stomach on the way there.
His hand reached its destination. Out of curiosity more than pleasure seeking he let one finger slip inside himself. It wasn’t much, a second joined it. That felt like something at least, he explored a bit, rubbing, sliding further in. His fingers were all the way in, down to the knuckle. He started rubbing, probing for the spot he had found on Karyn. His other hand came down, that one found his clit. He started gently working it. His moaning increased. He had to work to keep his volume down so that no one would hear him. Warm waves of pleasure spread out from his groin.
His fingers inside found their target. Again moans were forced out of him as he felt this new source of pleasure. He felt something begin to build, a tension. As he worked and enjoyed these new sensations the tension increased.
It built and built. He had to try harder and hard not to be too loud the more the tension built up.
Then release. He let out the most feminine sound his voice was able to make in the form of his climactic moan. He only barely managed to stop it from being a scream. He felt his vagina clamp down on his fingers as came. Waves of pleasure radiated through him, pushing their way all the way up to the top of his head. He felt his legs shake.
He started to come down. He felt the warm afterglow, though he also felt a sensation of emptiness down there. Part of him wanted to continue… but the water was starting to get cold. Besides… he could maybe go again in bed… and muffle himself with a pillow…
As he dried off he felt the arousal lower, down to a small little buzz, though he was left with an empty sensation, a desire. He could still feel himself firmly in female mode, even without the fact that all his male parts were still packed away inside him. One thing that surprised him after he had put on his pyjamas and started to walk to his room, was the way he walked, his hips swayed a little more. His walk was just a little feminine. One of the many little things being in female mode did to him.
He found himself thinking about Karyn… the fact that tomorrow night he’d be alone with her. His mind conjured up an image of Karyn on top of him in the tent, thrusting into him as he moaned… her boobs swinging with each thrust. He felt the wetness return between his legs. He would not be going to sleep right away tonight.
