Him & Her
Chapter 1 of a gender-swap sexual fantasy
{This post is very definitely NSFW; it is also entirely unsuitable material if you’re underage in your locality; only read on if you’re an adult and you like explicitly sexy stories.}
[Restraint, penetration by objects, gender transformation, pseudo-scientific language. All ‘participants’ are adult, imaginary, and entirely fictional - any resemblance to any real person is sheer coincidence.]
This story has been ‘gestating’ for a while now, on and off; on because I find the ideas behind it arousing; off because I thought it might be too similar to ‘Nurse Lisa and I’. It does share some similarities with ‘Nurse Lisa and I’ because it explores roughly the same kink/fantasy. I decided I would write it, and publish it, following yesterday’s ‘epiphany’ - I’m writing, primarily, for my own satisfaction, and there are areas of this fantasy which I think I want to explore in a different way. So here we are. Anyway, I hope you enjoy it!
“You both have to be strapped in, for your safety and, I suppose, ours.” the chief technician, Tina, said, as she bustled around, connecting things up. So many racks of electronics, so much cabling, linking it all together - so many winking LEDs of so many colours - a bit like an explosion in a Christmas decoration factory. “Shortly, we’ll get you both hooked up to all this and each other.” She, Tina, was a pleasant woman, probably in her thirties, with auburn hair and a slim figure, her white coat mostly hiding her figure, though it was failing to hide her nipples, which seemed to be aroused by something - and it clearly wasn’t the cold, because the lab was really warm. Perhaps she really enjoyed her work! It wasn’t clear whether she and Penny, the other technician, who was shorter, blonde-haired and more rounded, were wearing anything more than white coats and Crocs…
I looked across the lab, to where Beth lay on her couch, naked as the day she was born. My Beth; her of the huge tousled mop of dark brown hair - it was the first thing which had attracted me to her… It was almost like an ‘Afro’, but longer, looser, and wilder. I have a ‘thing’ about hair. It’s not really a ‘lust’ thing (although, I confess, long, usually wavy, hair is a turn-on), it’s more of an envy thing - and it’s not really that I just want long hair - because I could have that, simply by letting it grow out from my usual 6mm (¼”)! It’s more about wanting to experience being the person with the hair.
And that’s why I had booked this ‘Ultimate Experience’ at a new company - AGA (which stands for Advanced Gender Adventures). Beth, bless her cotton socks, isn’t what you might call ‘gender-curious’ in the way I am, but when I mentioned the idea, it piqued her interest… What might it be like to be a guy or, specifically, what would it be like to be me?
And so now here we were, ‘strapped in’ to these couches - my couch was so comfortable that I really barely felt that anything was supporting me at all. It was only if I tried to move that the soft, but firm, ‘harness’ which attached me to the couch showed how effective it was. A little movement was possible, but pulling against it met with increasingly firm resistance. My head was still free, and I could look across to Beth.
“You okay babes?”
“Yes, I’m fine,” she said, giving me a broad smile - the second thing which attracted me to her - a face which lit up with delight at the slightest provocation. She really was gorgeous, especially when she smiled. “Are you okay?”
“I must confess, I’m a little nervous, but I’m also excited. I wonder how it will all work? Will I still be aware of being ‘me’ or will I forget and be entirely you?”
“If I may interrupt,” said Tina, momentarily stopping what she was doing, “if we get the settings right, you should both entirely ‘become’ the other; every sensation you feel, every thought, or dream, or experience, should feel exactly like what the other’s body feels… Or would feel, except that instead, they’re feeling what you would feel if you weren’t feeling their feelings.
It doesn’t happen to everyone, but you may experience a sort of body dysphoria; the differences from your normal body may impinge on your experience - perhaps the most common being the gender differences - but smaller things can sometimes seem more noticeable, such as being hairy or smooth-skinned when your ‘real body’ is accustomed to the other; that makes clothing feel quite different, or so people tell us afterwards. If you know these things now, you should ‘settle in’ to the roles more easily.”
“That’s roughly the sorts of things they said while they were explaining the procedure when we were booking. I think I get it.” I said.
“It should all become clear - and very pleasurable - once we actually get started. I’m sorry it’s taking so long, but as I’m sure you’ll appreciate, the human mind and body are extremely complex, and connecting them in this way, so they both experience each other’s feelings, and also experience each other’s ‘actions’, albeit in a dreamlike trance, is also very complicated.”
They carried on with their preparations by getting out of the cupboards a series of bags and cases marked ‘STERILE’, each containing various ‘instruments’ - several contained things which looked just like dildos, albeit dildos with electrical leads attached, with complicated-looking multi-pin plugs on the end.
I looked across at Beth, lovely Beth. Known at school, apparently, as Beth Big Boobs, because she was the first in her class to begin to develop, the first to wear a bra and, so she says, the one who ended up with the biggest breasts. She really was delightfully curvy, in an athletic sort of way. Her legs were well-muscled, so they were shapely without being ‘chunky’, and the same went for the rest of her. She wasn’t fat, but she definitely wasn’t a ‘stick insect’ - just about perfect, to my eyes. Her bum wasn’t overly large, but was beautifully rounded and, oh boy, could she twerk it! Her boobs were, well, quite spectacular. They were large with just the right amount of sag, without being completely OTT, and quite firm and bouncy - as well they might be, at twenty-two years old. Topped by perky pink nipples atop barely visible ‘stealth-pink’ areoles (which became really ‘bumpy’ when she was turned on), they were perfection personified.
Just looking at her was making my cock start to twitch and grow - that and the thought of the experience due to start very soon.
Tina, now wearing fine latex gloves, was leaning over Beth, speaking quietly. First she attached a set of what I recognised as electrocardiography leads, on sticky pads, to Beth’s chest, wrist and ankle, then she put a pair of different sensors around her nipples, which immediately pebbled into erection, popping the sensors off, to a slight tutting from Tina, who replaced them.
At this point my attention was taken by the arrival of Penny at my couch, bearing a tray with a number of other ‘STERILE’ bags, not dissimilar to those which Tina was busy opening and fitting to Beth.
She fitted the ECG harness, leaning over me and giving me rather a good view of her cleavage down her white coat.
She opened the first of the bags, which contained what was fairly unmistakably a butt-plug - fairly slim, but a butt-plug nonetheless. It had, of course, a thick cable protruding from it, ending in a complex multi-pin plug.
“Have you ever worn a butt-plug before?”
“Once or twice, but I couldn’t say I’m a regular, or experienced, user. I’m not really a big fan either - they don’t really do much for me.”
“Okay, good job this anal probe is fairly slim…”
“Anal probe? I interrupted, laughing nervously, “This is beginning to sound as though we’ve been abducted by aliens!”
“Damn! Tina - we’ve been found out.” she laughed. “Yeah, we’re aliens okay; under these silicon body-suits we’ve got scaly green skin and lizard eyes. Oh, and tails.”
I laughed, but just slightly hysterically.
“No, but seriously, I’m as human as you are! Here, see…”
She opened her coat, showing me her pussy, the lips glistening and swollen.
“Well, it looks real enough.”
She moved closer, and pressed her hot, slick, pussy against my restrained hand.
“Ok, ok, I believe you’re not a space alien!”
“Right, enough of the frivolity. I thought we’d tackle the most difficult job first. And I would say that, if you think you don’t like butt-plugs, you just haven’t found the right one. I guarantee that you’ll love this one. Right, I’ve undone your ankles, so please pull your knees as high up toward your chest as you can.”
She squirted a big blob of lube onto the plug, and rubbed it in, finishing up by ‘wanking’ it whilst looking me right in the eye with a rather lewd expression. She applied more lube to my anal area, and eased a finger inside, making me shudder and causing my cock to twitch involuntarily.
“Relax as much as you can - the more relaxed you are, the more likely it’ll go in easily.”
She withdrew the finger, placed the tip of the plug against my tiny opening, and began to push, gently at first, but with steadily increasing pressure. I felt it begin to open me up; I resisted the tendency to clench up, and instead followed her advice and relaxed as much as I could. It began to slide in, and went in with a rush in the end, as it passed the sphincter. It actually felt quite nice - I was pleasantly full.
“You can relax your legs again now.” She moved to my ankles and secured them once more.
“We’ll just test that - it’s quite important it works properly.” she murmured, moving to the nearest rack of instruments, plugging it in, and flicking a couple of switches. Immediately I felt warmth and a tingling sensation deep in my insides. My cock twitched again in response.
“Fuck, I’m getting turned on already, and we haven’t even started.”
“That’s good,” said Penny, “you’re nicely responsive, so this should go really well. By the way,” she said, conspiratorially, leaning over me and giving me an even better view of her gorgeous boobs jiggling in her white coat “you have a really lovely cock - it’s tempting to just mount you and ride it, but that would end the experience prematurely, you wouldn’t get your money’s worth, and it would land me in huge trouble. This job can be quite a turn-on sometimes.”
Her words made my cock rear up still further.
“That’s good,” she said, “this sleeve goes on a lot easier if you’re properly hard.” She grasped my cock and squirted a big blob of lube onto the tip, spreading it quickly and efficiently, before taking what looked like an incredibly sophisticated male masturbator, all sensors, LEDs and wires, into the orifice of which she squirted yet more lube, before easing it over the head of my cock and pushing so it slid easily down, despite being quite a tight fit, enveloping my cock to the hilt.
“We’d better test that too,” she said, “if that doesn’t work, we’re screwed… Or not, as the case may be!”
She secured it to the harness around my hips, and then plugged its cable into the rack of instruments, flicked another few switches and adjusted a dial. I felt a faint buzzing, some warmth, and vague suction for a moment.
“Haven’t you finished yet Penny? Stop playing with his cock and finish your work.”
“Yes boss! Just the nipple sensors and gloves to fit.”
While Penny was fitting the sensors to my nipples, and fitting gloves, again with a loom of wires attached to them, to my hands, Tina took the largest of the items, which was best described as a ‘helmet’, incorporating a VR headset, and was also attached to the electronics by a big loom of cables, and held it where Beth and I could both see it.
“As I’m sure you’ve been told, all of this equipment is inherently safe - it runs at very low voltages and currents, and there is no risk of electrocution. What it does, is to record your neurological and physiological responses, and respond by feeding appropriate stimuli back to you. Next door, through that wall, is an impressive array of computing power, which is able to ‘keep up’ with both your minds, and provide a realistic virtual environment, complete with virtual ‘extras’ in your scenes. Once I place these helmets on each of your heads, the only audio and visual stimuli you receive will be from the helmets. You, and your responses, will be monitored constantly, and the experience terminated at the slightest sign of distress or anything else untoward. Are you ready?”
We both nodded, slightly nervously. “Okay, just relax. There’ll be a few moments of quiet, and darkness, while the instruments calibrate their settings to you and load the scenario.”
She took the helmet and strapped it on Beth’s head, helping her settle comfortably into the couch, before coming across to me, picking up my helmet in turn and securing it to my head.
It was, indeed, dark, and quiet apart from a faint background hum.
