“Honey, I’m home,” Vic called out, closing the front door behind him. Padding further into his apartment, he stretched his arms and blew out a big breath. That had been a good workout. He’d had more free time today than usual, so he’d been able to work out for longer and do more varied exercises.

As he flexed his tired (but not overwhelmed) biceps, he grinned. Thanks to a fairly regular gym schedule, he was still almost as fit as he’d been back in high school, when he’d been on the football team. A low chuckle followed a flash of memory, of a cheerleader admiring his muscular arms and even daring him to lift her into the air. He’d obliged, much to her obvious excitement.

Yes, as one of his school’s hunkiest athletes, he’d had plenty of attention from the ladies. He’d lost count of the phone numbers that had been passed to him, the overeager fangirls and shyly blushing lab partners, the high-pitched giggles and provocative whispers in his ear. But he’d rarely responded to their advances, because, truth be told, he only ever had eyes for one person.

“Hey babe,” Samuel said, smiling at Vic from the couch. “Good workout?”

“Yeah, it was great,” Vic replied, approaching his boyfriend. “How long have you been home?”

“Like, ten minutes?” Samuel covered his mouth with one hand as he yawned. “Been a long day...”

“Well, I hope you’re not too tired,” Vic chuckled. “I’m on quite an adrenaline high right now, and I was hoping we could make the most of it...”

It was as if those words had magical revitalising powers - Samuel immediately sprang to his feet, seemingly fully re-energised. “I’ll find a way to power through,” he said with a grin, drawing close to his boyfriend.

Samuel had been one of the ‘cool kids’ at their high school - a handsome but quiet loner, exuding a subtle charisma that made people keen to be near him. In his own way, he attracted about as many female admirers as Vic did. So it astonished the football player when Samuel had revealed, partway through their senior year, that he reciprocated his feelings in full. They had been together ever since, throughout college and beyond.

Vic couldn’t imagine being with anyone else. If he had been, any such fantasies would have been dispelled the instant Samuel’s lips touched his, as his wiry arms wound around Vic’s torso, pressing his chest against Vic’s abs. He could feel Samuel’s hard-on against his leg, through both their pants.

Breaking off the embrace, Vic turned and walked towards the wall, pulling Samuel behind him with one hand, fumbling with his gym shorts with the other. “Take me from behind,” he gasped, smiling lustily back at his partner. “Fuck me hard, please...”

Samuel needed no more encouragement. Letting go of Vic’s hand, he quickly unzipped his pants, allowing his thick cock to spring out. At the same time, Vic slid down the back of his gym shorts, exposing his round, firm ass.

Placing a palm against Vic’s back, Samuel pressed him against the wall. Then he stepped forwards and teased Vic’s crack with his tip, eliciting needy whines that no-one would’ve expected to come from such a powerful, manly figure. No-one, that is, except Samuel - who suddenly thrust forwards, spearing Vic with his cock, impaling him against the wall.

Vic moaned gratefully. I’m happiest when I’m full, he thought. This was followed by, where the hell did that come from? But any confusion about the random notion was driven from his mind as his boyfriend moved back and forth inside him.

They continued in this vein for a minute or two, the slight figure fucking the muscular one, pinning him to the wall, both of them grunting and groaning loudly, sweat dripping from their bodies. Finally Samuel pulled out and stepped back, leaving a whimpering Vic slumped against the wall.

“I need water,” Samuel gasped. He chuckled at the sight of his panting boyfriend. “You should probably get some too!”

Weakly nodding his agreement, Vic pulled up his shorts and followed Samuel to the table, from which they collected a glass of water (Samuel’s) and a half-full bottle (Vic’s, which he brought with him to the gym and back). As Vic picked up the bottle, he noticed a piece of paper underneath. Frowning with curiosity, he picked it up with his other hand and held it up.

Samuel watched him do so, as he took a gulp from his glass. “What’s that?” he asked.

Before Vic could answer, he read the three words on the paper - ‘Ross prophet swap’.

He felt a strange thrill go through his body, making his skin tingle, and inhaled sharply. He heard a gasp from across the room, and looked up from the paper to see Samuel staring at him in open-mouthed shock.

“What’s wrong?” he asked - and then caught his breath. That wasn’t his voice. It was higher, softer, more melodious...

“What the fuck?” he blurted. “What... the... fuck...” he repeated slowly, listening to the words, to the specific tone he used with each of them. There was a recognisable hint of his own voice, but other than that, it sounded like...

“V-Vic,” Samuel stammered, gesturing towards him. “Look at yourself!”

Glancing down at his own body, Vic’s own mouth fell open at the sight of the round, perky C-cup boobs that had suddenly appeared on his torso. And that wasn’t the only change - he could feel an absence within his shorts, but to be certain he started to reach down with one hand. That hand stopped in mid-air, as he noticed the slender, dainty fingers. His arm was still strong and muscular, but the skin was softer and silkier. Long blonde hair hung down from his head, draping over his shoulders and chest.

Continuing to reach down, he slid his hand inside his shorts, and found that while a certain something was missing, there was something else. Something that took up much less space, and was quickly and unexpectedly getting tender and wet. Vic shook his head in amazement - and, to his own surprise, excitement.

“Babe,” he - she - whispered. “I’m a girl!”

***

Samuel stared in shock at his transformed boyfriend. At first, the changes seemed drastic - the heaving breasts drew immediate attention - but the more Samuel looked, the more he noticed that Vic actually didn’t look all that different! It was as if every aspect of his appearance had been tweaked to be a little more feminine. His eyelashes were longer, his lips were fuller, his hair was longer and blonde rather than brown... His physique was no less muscular - and yet, it felt as though he had lost a little power, and presence. Vic had always been relatively short, and perhaps his height hadn’t actually decreased any further, but in this female form he still seemed smaller, somehow.

Samuel guiltily wondered if thinking like this was anti-feminist. But those concerns were way down his list of huge questions. Number one on that list was: what kind of dark magic fuckery had turned his boyfriend, the pinnacle of manliness, into a beautiful woman? And number two - why was Samuel, who couldn’t remember ever being interested in anyone or anything other than hunky guys, finding Vic’s new female form very attractive?

Vic clearly had questions of her own, which Samuel could quite understand. “How did this happen?” she blurted. “Is this magic, or something? Was that note some kind of spell?”

Samuel decided to try to restore order. “OK, don’t freak out, we’ll figure this out - just calm down, Vic...”

“Vicky,” his transformed boyfriend blurted. She blushed. “Uh... I don’t know why I said that,” she admitted. “It just... felt right. I guess because I’m in this body...”

Samuel bit his lip, considering this. ‘Vicky’ seemed to suit her, to be fair. The name had a sort of playful, feminine quality to it that fit with her new form. It was odd that she had thought of it immediately, though - just as odd as the way Samuel had started mentally using female pronouns to refer to her, which he’d only just noticed...

He stepped towards Vicky, studying her face intently. “Do you... like it?” he asked hesitantly. “This body?”

Vicky took a long time to answer, her hands roaming over her clothes and exploring her new curves as she thought. “Yeah,” she eventually mumbled, before laughing in apparent surprise at her own answer. “I kinda do!” She stared at Samuel. “Do you?” she asked nervously.

“Yeah,” he immediately replied, eyes widening in astonishment at how quickly he’d answered. It was true, though. For some reason, his boyfriend’s new female form was getting him extremely hot. He admired her eagerly, drinking in the sight of her, undressing her with his eyes. Reaching out with both hands, he took hold of both sides of her head and ran his thumbs over her face, luxuriating in the smoothness of her skin. She whimpered as his fingers probed her lips, opening her mouth slightly to grant him easier access. One of his hands drifted down to her chest and began to grope one of her ample tits through her shirt. She made no move to stop him - if anything she pushed herself forwards a little, pressing her boobs further into his grasp.

Why was he so turned on by this womanly form? Was it because he knew it was still his love in there? Was he slightly closer to the middle of the Kinsey scale than he’d previously thought? Was it because of how cute and vulnerable Vicky was? Samuel didn’t know. All he knew was that he wanted to explore her new body. He wanted to know her intimately. He wanted to fuck her senseless. He wanted to push her to her knees, pull her hair, slap her rosy cheeks...

Where were all these ideas and feelings coming from?! It was true that Samuel had always been the top in their relationship - which may seem strange from the outside, given how Vic towered over him. But despite his assertive past role, Samuel had never had the desire to dominate Vic the way he wanted to dominate Vicky. It was almost all he could think about.

“Take your shirt off,” he ordered, again surprising himself - this time with the firmness of his tone. That was the voice of someone in control, someone who expected to be obeyed.

“Yes, Master,” Vicky whispered. Her eyes widened as she realised what she’d just said, and she blushed and averted her gaze. But she did as she’d been told and removed the shirt, exposing the bouncing treats beneath, and her thighs rubbed together gently, clearly indicating how turned on she was getting.

Samuel’s jaw dropped, as he was overcome with surprise and arousal at being called ‘Master’, seeing Vicky obey his commands, and getting to see her bare breasts. It was all a rich tapestry, and it was making his cock feel like it was about to burst free of his pants.

He took her by the throat, and she smiled excitedly as he tugged her closer towards him. He kissed her, gently at first, then with increasing force, still grasping her neck. He slowly pushed her backwards across the room as they made out, until her back met the wall. As he pressed her against it, pinning her there with his body, she lifted a leg and wrapped it around his waist. His mouth moved down and worked its way across her neck and shoulders, kissing and biting as she gasped and moaned.

Samuel wanted to take his cock out and plough it into Vicky’s newly-minted cunt, but something stopped him - some instinct told him to wait. So instead, he released her and took a step back, leaving her slumped and whimpering against the wall, just as Vic had done before his transformation.

“Kneel,” he said simply.

“Yes, Master!” Vicky gasped happily. As she sank to her knees, eyes wide and guileless, Samuel undid his pants, and his cock jumped out once again. Vicky’s eyes fell on it, and she eyed it hungrily.

“What do you want, Vicky?” Samuel teased. He was really starting to enjoy this sense of power.

“I want your cock, Master,” Vicky sighed longingly.

“Beg for it.”

“Please, give me your cock, Master... I need it...” She gazed up at him with desperation in her eyes. “Please, Master - fuck my face, hard!”

Well, how could he say no to that? He seized her by the hair and commanded, “Open wide...”

No sooner had she complied than he thrust his cock into her gaping mouth, ramming it down her throat. She took it without struggle or complaint - clearly, her ability to take a throat-fucking without triggering her gag reflex was one of the few things unaffected by her transformation from man to woman. After a minute or two of this, he let go of her hair and his hips halted their vigorous movement, letting her take over. She adjusted her own movement to compensate, rapidly sliding her mouth back and forth over his shaft.

Finally, with admirable self-control, Samuel pulled out, both him and Vicky panting and moaning. “Crawl after me,” he told her.

“Yes, Master...”

Leading her through to their bedroom, he had her lie on the bed and pull off her shorts, revealing a slick pulsating pussy - the first Samuel had ever seen. He was instantly enamoured of it. As she spread her legs wide at his command, he clambered onto her and stuck himself inside her, unable to wait any longer to feel the sensation of his cock inside pussy for the very first time. She cried out as he thrust his hips back and forth, fucking her with vigour. His hands seized her wrists. His eyes met hers.

“What are you?” he grunted, not really sure why he was asking.

“W-weak and dumb, and helpless,” she mewled. Her face lit up - clearly, she’d liked saying that. He’d liked hearing it. “Weak and dumb and he-eelpless,” she groaned again, as he sped up, surging within her. “Weak and duh... dumb, and helpless!”

She kept trying to repeat the peculiar but erotic phrase as long as she could, but eventually the fucking got so intense that neither of them could do anything but relentlessly thrust towards each other. Finally, almost in sync with one another, they came, long and hard.

Pulling out of Vicky, Samuel rolled over onto his back. His eyes fell upon his cock, and he frowned. Somehow - in spite of having orgasmed with such force that he didn’t think he’d be horny again for at least a day - it was still fully erect, thick and hard. To his left, he heard Vicky begin to giggle.

He turned his head to look at her, an eyebrow raised. “What’s so funny?”

“I remember now,” she sniggered, turning onto her side to gaze at him. Before he could ask what she was talking about, she said, “Freakish mouse laces.”

And then everything became completely clear to Samuel - or rather, Samantha. Her mouth fell open with astonishment as her true memories and personality came flooding back into her mind.

Lying back and staring at the ceiling, she let out a long awestruck whistle. “Fu-uck me!”

“I just did,” Victoria pointed out, laughing.

***

Sometime later, after they had both showered (separately), the girlfriends snuggled up on the couch, clad in their matching fluffy purple dressing gowns. “So,” Victoria purred, nestling her head into her partner’s shoulder, “was that everything you’d hoped it’d be?”

“Yeah,” Samantha said slowly, as she contemplated how she felt about the hypnotic escapade. Turning them both into men had been her idea - she’d made a file for Victoria, who had listened to it and been transformed into ‘Vic’ after she’d hypnotised Samantha into becoming ‘Samuel’. It hadn’t been long since Samantha had started getting hypnotised herself - before that, she’d always been the mesmeriser, and Victoria the mesmerisee. But after months of gradually (and consensually) reshaping Victoria into Vicky, a meek, whimpering mess of a slavegirl, Samantha had finally gotten her turn. She’d had a list of suggestions and scenarios she wanted to explore - and gender play was top of that list.

“It worked so well,” she continued, an incredulous smile spreading across her face. “I genuinely thought I was a guy - I had this very specific image of myself in my head, of how I looked. I was picturing, uh, Murphy, from The 100? You remember that show?” She was met with a shrug - Victoria hadn’t seen it. “Uh - well anyway, I looked down at myself, and I didn’t see my boobs, or my long hair, or anything that indicated I was a girl. And the strap-on - it felt like a real cock, like it was really part of me! I felt sensations in it - when you were sucking it, I felt your lips around it. When I was fucking you, I felt myself inside you...” She sighed softly at the memory. “Um, and you - when I looked at you, I saw a hunky guy!”

“Huh. It was kinda different for me,” Victoria mused. “I didn’t see myself or you any differently - when I looked at you, I still saw you, not a guy. But I just didn’t notice that you were a woman, or that I was. It’s like, my brain had already decided we were dudes, and it wouldn’t take in any evidence that we weren’t. But when I read that trigger, suddenly I noticed everything about myself - all my womanly features.” She smiled with faint embarrassment at her choice of words. “I was seeing myself, but it was like it was the first time...”

Samantha opened her mouth to speak, but then hesitated, averting her eyes. Victoria stared at her, unaccustomed to seeing her girlfriend unsure of herself, but waited patiently for her to find the words. She knew better than anyone how hard it could be to come up with the right way to explain how a hypnotic experience felt, particularly in the brain-scrambled afterglow of a session.

“Do you, uh...” Samantha trailed off, then started again, making an effort to make eye contact with her girlfriend. “Do you ever have these moments where you feel like... like a guy?”

Victoria’s instinct was to dismiss the idea immediately, but she humoured Samantha and thought hard about it. “Not really?” she said at last. “I mean, I know I’m not much of a girly girl - or at least I wasn’t, until you started fucking with my brain and turning me into Vicky,” she chuckled. “But no, however, uh... tomboy-ish I’ve gotten, I’ve never felt like anything but a woman. I’ve always felt pretty sure of my femininity.” She met Samantha’s gaze evenly. “What about you?”

“Um, well... sometimes? I mean, 95% of the time I feel, like, womanly - and really feminine! But then I have these days, or even just these momentary... flashes, I guess you could call them, where I feel like maybe I’m... not? Like I’m - or part of me is - a man.” She closed her eyes and shook her head exasperatedly. “I’m not explaining this very well!”

“It’s OK,” Victoria reassured her. “It’s confusing, I get that! But, I mean, gender’s a spectrum, right? It’s probably normal for you to have these flashes - these moments when you feel like a guy...”

“It felt so real,” Samantha said quietly. “Being a man - being Samuel. It felt... right? But I don’t know if that was because it was right, or if it was just the novelty... or if I just liked having a dick!”

They both laughed.

“Look, I’m no expert,” Victoria said, “but it sounds like maybe you’re genderfluid. Or at least a bit genderfluid. There are people who feel like a different gender from one day to the next - Monday they’re a guy, Tuesday and Wednesday they’re a girl, Thursday through Friday they’re neither... Maybe that’s you, but just to a lesser extent. Like, one day every six months or whatever, you’re a dude, and the rest of the time you’re a woman...”

Samantha nodded thoughtfully. “Yeah... Yeah, maybe.”

Sensing her girlfriend was still confused and uneasy about the whole topic, Victoria snuggled closer to her, wrapping her arms around her. “Y’know, you don’t have to figure all this out now. Some people take their whole lives to figure themselves out! Think about it some more when you’re not coming down from hypno fuckery. Do some research. Maybe talk to a therapist or something. And keep talking to me about it, because I want to help if I can.” She smiled gently at Samantha. “I’m really proud of you, baby. You’re so brave, being willing to explore yourself like this, and to tell me about it...”

Samantha looked surprised and delighted. “Really?”

“Yeah, it shows real courage!”

Victoria was met with a grateful smile from her girlfriend. “Well, it’s easy to confide in you,” Samantha mumbled, moving her face closer. “You’re always so...” She opened and closed her mouth, clearly struggling to find the right words again.

Victoria grinned. “I know. Everything you want to say, I know.”

They kissed softly, unhurriedly, beginning a makeout session that was the opposite of Samuel and Vicky’s forceful meeting of lips earlier. When they finally parted, Samantha spoke quietly. “I want you to do something for me, Vicky.”

Victoria felt her mind start to go fuzzy, as her girlfriend’s words began to draw out her slavegirl side. “Anything, Mistress,” she mumbled, blushing as she felt her intelligence and willpower melting away.

“Until I say otherwise...” Samantha hesitated for a moment, and then grinned wickedly and said, “Call me Master.”

Vicky smiled broadly. “Yes, Master!”
