Digimon:Gender evolution
HI there, know it has been a while since I uploaded anything. Still struggling with my drive and honestly, don't see it improving any time soon but I will keep writing even if here and there.
This story was inspired by a female Guilmon image I saw in my collection, it struck me that if Guilmon became a female she would be very clueless and same as usual, but with a helping hand she discovers she is not the only one affected and awakens to her more intimate side.
All characters belong to Bandai and their respective partners and I own none of the characters or franchise.
It was late at night in the Matsuki residence, probably getting on around midnight. The bakery below their home was dark and quiet, and only the odd light going off and on in the hallway as Takato's parents made the odd trip to the bathroom.
A hot summer night, the odd owl hooted outside the window. However, a glow of a different type and source was emanating from inside the young trainers window as a certain dinosaur Digimon underwent a transformation.
“Takato...Takato?" a female voice whispered into his ear, the squeak in her voice gave her a sultry, playful sound.
“W-who's there?!" Takato mumbled, alarm forcing him from his sleep. It was too different a tone for it to be Juri, and it definitely wasn't Rika or Renamon, meaning he had a stranger who knew him, in his bedroom. “L-look, I don't know what it is you want but you have to leave," he started stuttering, rubbing the sleep from his light, red eyes and turned the light on...only to get a good look at who was straddling his body, pinning him in bed.
Eyes bulging as he took in who the figure was. It looked like Guilmon, but...it wasn't in so many ways.
For starters the red dino type digimon before him had curved, seductive eyes, a shapely and smooth looking body with wide hips and a large and shapely rear. The toned legs ending in large clawed feet and, most prominent of all, a pair of huge, shapely breasts with light red nipples capping the huge mounds.
“Uh...Wh-WHAAAHH!" He cried out in alarm, throwing an arm over his eyes to stop him staring as the red Digimon jumped off.
“Takatomon wait, it's me, Guilmon!" she cried out through her more smoother, sleeker muzzle, waving her clawed hands in panic.
“No, no, no, no! You can't be, it's impossible!" he cried out, his face turning as red as the dino girl.
“Is so, Takato. I woke up like this for some reason and feel funny," she said, her bat like ears drooping as she crouched to the floor low, giving him a good look at her canyon cleavage and thrusting the shapely rear up to good effect with that long tail waving in agitation, sleeker and more alluring somehow.
“You...you can't be, there's no way…" Takato mumbled, glancing from under his arm before quickly covering his eyes again, feeling like his young boyhood would explode should he take in more of her.
But then...was it? A wild Digimon had come through to their side in the form of a giant, black, sinister looking bug that looked like a giant Stag beetle by the name of GranKuwakamon.
Rika and Renamon were digivolving to their mega form but this viral Digimon, it was an exceptionally vicious type. He and Guilmon had no time to fuse, so was trying to stall the Digimon in Wargrowlmon form.
However, they had to dodge to save themselves from being cut in two by its devastating pincers, charging towards the fusing pair.
“Guilmon!" Takato had cried out to his partner.
Whirling around, the giant, part robot dinosaur charged towards Renamon and Rika as fast as his jets would allow, scooping them up in his giant metal hand and interrupting the fusion.
An event like this had never before happened, and the four thought nothing of it as MegaGargomon charged in, blasting the viral type and forced it to retreat.
“No way," Takato mumbled again, head in his hand as he played the days event over in his head before nodding. Snatching up his goggles, he dressed himself and reached for the handle. “It probably isn't a good idea to follow me right now Guilmon now you look like that, it would be better to stay indoors," he said, not looking at her.
“But…" Guilmon said, her voice sounding husky in her whisper, causing Takato's heart to thump in his chest.
“I said stay Guilmon," he said, feeling his young shaft stir again before opening the door and made a hasty exit.
“Takato...I won't give you cooties," came Guilmon's low, sad voice as she was left in the dark and loneliness of his tamers bedroom.
*
With not a lot to do and not wishing to upset her tamer any more, Guilmon sat bored and though she tried to sleep, she just felt...hot and itchy below.
Sitting on the edge of his bed, Guilmon's claws idled along her new body, finding that unlike before, her scaly skin, once rubbery and slightly rough, was now supple and smooth and felt so much nicer to touch and stroke.
Then there was her new additions; now she had a heavy set of breasts, larger than the set Renamon hid under her fluffy mane. Looking down at the large rack she now sported, a clawed hand wandered over to tease a light pink nipple.
“Ooh, that feels funny, but in a nice way," she moaned to herself, her claw tracing in larger circles around her areola, a warmth spiralling from her new, sensitive nipples to her also new pussy lips, tucked away between her thick thighs.
“What's that smell, it smells...of me, but good," she panted out, her breath coming out in hot pants, her claw reaching down, going between her legs before she tensed as she came into contact with her slit, the same in colour to her nipples.
Tensing at the touch, she moaned in relief as she rubbed up and down a few times before raising her claw to her muzzle, a string of her juices hanging off it all thick and sticky. Sniffing curiously, she stuck her tongue out, lapping her taste off before licking her lips.
“I taste good," she said in playful innocence. Realising she would get more with her tail, though slender than when she was a male, she rubbed the length under her legs, standing up for better access and raised her tail to her lips, licking again, and again, and again as she only grew wetter and hotter and more playful.
“This feels...really nice, and I taste better than fresh bread," she moaned, muzzle open as she panted, horny for the first time and clueless to the feeling. “I wonder if I can…" she then grabbed her legs and bent her neck up, burying her muzzle in her pussy and lapped and lapped, drinking greedily of her own juices with her tail wagging excitedly.
Only, the door suddenly opened with Takato and Rika entering the room, pausing mid-talk as they had a clear view of Guilmon eating herself out.
Hearing the door open, Guilmon lifted her head up, muzzle covered in her sweet juices and smiled, “Oh hi Takato, Rika. I never knew I was this flexible. Hey, I taste really nice, want to join me?" she said in her childish innocence, licking the juices off her muzzle.
Takato stepped forward, hypnotised as his young, adolescent mind was drawn to her, his dick leading the way as it strained his pants.
Rika's jaw hung slack in wonderment before shaking her head, having the strength of will to resist and grabbed him by the collar.
“Ow!" Takato cried as he was sharply yanked back and pushed out the room.
“Takato, me and Guilmon here are going to have a ladies chat, understood? If you even think of entering you'll have my shoe stuck up your butt. Got that?" she said cooly, slamming the door shut.
“But it's MY ROOM!" Takato cried out in outrage, only for his parents door to open and having to come up quick with an explanation of what he was doing out of his bedroom with the door closed and shouting.
Ignoring Takato, Rika turned to Guilmon who had gone back to playing with her breasts.
“Guilmon," Rika said in a low, stern voice, slapping her paw away and getting her attention.
“What? They feel so bouncy and fun I can't help it," she said in a sullen tone, her bat ears going to the side.
“That is besides the point," she said, glaring at her. “For one it is shameful to behave in such a manner in front of someone else," the red headed human tamer said, her icy blue eyes roaming her form. “Damn it, she Does look really cute though…" Rika found herself thinking reluctantly.
“Then there is the fact of what to do now we can't fuse to form our Mega forms. Since I and Renamon can no longer change since you swapped genders with him, the same would hold the same for you."
With that, a gentle clunk sounded as Takato crept back in his bedroom, Rika whirling round on him.
“Sorry but I kinda have better things to do than stand outside my room. And what is this about Renamon now a guy?"
“Yes, it is...uncomfortable to say the least," a deep, male voice suddenly sounded from Takato's side, causing him to jump in alarm.
“You know...that never gets any less alarming how you just appear out of nowhere," he complained as Renamon took her, or rather his, place at Rika's side, giving Guilmon a sidelong glare through his deep blue eyes as though this was all her fault.
Aside from the deeper voice, Renamon had changed very little compared to Guilmon. He had a slightly taller build now, a thicker tail and chest fur and a little more below that only just covered up his sheath.
“Oh wow, now you have a sausage huh Renamon?" Guilmon said, taking a good interest in his crotch before Renamon clonked him on the head, the changed dragon type scuttling back whilst rubbing her sore spot.
“Yes, and now we can no longer fuse which present us with a big problem," Rika said, folding her arms in front of her barely there chest. “The only thing I can think of at this point is to try and spend time around the others Digimon, swap our Digivices and hope we can fuse to change things back the way they should be," she announced, swiping Takato's device from his bedside and plonking her own there.
“Hey, now wait a minute!" Takato said as Rika grabbed Guilmon by the claw to lead her out.
“Well...I guess. I mean, Renamon doesn't look too happy about how he looks now Takatomon...I think we should try," Guilmon said in a resigned voice.
“Guilmon…" Renamon said in a gentle tone before nodding. “I think they have a point Takato. Though I don't see you as my tamer, I see you as a friend. Maybe if we spend time we can reverse the change, I do miss my body already though...Guilmon looks settled," he said with an envious look.
“Well...then I guess it is settled then," Takato said with a resigned shake of his head, “besides I know when I'm beaten."
Turning to Renamon, he held his hand out to shake the furred kitsunes paw.
“I know this will be weird to start with, but I will do all I can to forge a strong bond with you Renamon," he said with a forced look of confidence.
Harboring serious doubts, Renamon shook his hand in his large paw in agreement. “You'll never replace Rika," he thought to himself.
*
Two weeks later down the line and the four of them were no closer to evolving still. They had tried nearly everything to evolve together but no matter how hard they tried, nothing worked.
“Again Guilmon, you're just not trying hard enough!" Rika said angrily as she was in the process of training the red virus type in her garden.
“I-I'm getting tired, and hungry," she complained, “plus your mums clothing feels weird when I train," they had resorted to using her mother's clothing to better cover Guilmon up since Rika's own was much too small for the now busty Digimon.
The shock her mother had when she found Rika with a different and more revealing, Digimon was something she found hard to get over. She even joked about Rika being a lady magnet what with Renamon and now her, to which she earned a good days worth of silence for.
“You sure eat a lot more than Renamon, that's for sure," Rika groused before sighing reluctantly, “okay fine. We're not going to bond if I work you to death. You've earned a break Guilmon," she said before laying on the grass for some chill out time herself. “Just don't let me catch more than one loaf of bread missing okay?"
“Okay Rika, I promise," Guilmon agreed though with a bit of a sour note in her tone. She sure had a lot less bread here to eat than with Takato and didn't taste the same cold.
Retreating from the day into the kitchen, she was making her way over to the kitchen when a paw suddenly covered her muzzle, keeping the red Digimon from crying out in fright.
“Its me Guilmon, I don't want either of them knowing where I am," Renamon said quietly before releasing her muzzle.
“Hi Rena, mmph!" she mumbled as Renamon quickly silenced her again, closing a hand round her muzzle.
“What part of 'I don't want them knowing I am here,' did you not understand Guilmon?" he whispered, a scowl on his beautiful, furred face.
Using his teleport ability, Renamon whisked them as far away as he could, finding themselves in a wooded reserve.
“Those clothes don't really fit your form," Renamon said as he eyed up the changed Digimon.
“Oh? I can take off?" Guilmon said eagerly, already starting to strip off.
“What no...oh come on," he mumbled with a hand over his face, Guilmon wasting no time in discarding the top and bottoms, leaving her in the nude; her light, pink nipples stiffening in the gentle breeze.
“Ahh that feels nicer without, Guilmon no care for human clothes," she moaned, stretching out, showing her chest off to full effect with a gentle jiggle.
“Guilmon...I really think you should put those back on...right now," Renamon said in a low voice as he felt strange stirrings from his new male parts. His fluffy tail started to twitch and swish as he wrestled with these new sensations before seeing Guilmon staring at something.
“Wh-what are you looking at Guilmon?" he muttered, crossing his arms and twisted away partially.
“I-I don't know...just Renamon smelled good and well, you have a nice looking sausage Renamon," Guilmon said, her ears half way in a blush.
“What?!" Renamon gasped as he looked down, eyeing his impressive six inch of tod meat, standing out from between his strong, furred thighs as though proud to be there.
Thinking fast, Renamon covered his member with his fluffy, thick tail before turning away.
“Why Renamon so shy? I think you look good," Guilmon said, though she noticed her thighs were starting to become moist from her own dampening slit.
“N-no it doesn't! And this is what I wanted to talk to you about, how the hell do you control this thing? It grows whenever I start to think about Rika and…" his face fur blushed when he realised he had said too much.
“Oh? Rika and Renamon, sitting in a tree, K I S S I N G," Guilmon sung playfully.
“That's it!" Renamon growled before pouncing her, taking Guilmon by surprise.
“G-get off me Renamon, I was only having fun!" She growled and thrashed under her, her thick tail thumping the ground in distress.
That was when it happened, with Renamon on top, the tip of his fox cock slipped into Guilmon's passage.
“A-ah! Renamon that's gross, that isn't supposed to go inside my body!" Guilmon cried out as he felt her lips wrap around the head snugly.
“Idiot, that is exactly what a females pussy is there for besides peeing out of!" Renamon bit back the moan in his own voice, pulling out with a shiver of pleasure. “That never would have happened had you not taunted me," he huffed, crossing his arms in front of his furred chest, covering his throbbing cock up again with his tail.
“I didn't mean to get you angry Renamon, I was just having some fun," Guilmon muttered, her arms folded under her breasts, pushing them up and only making them all the more enticing.
Renamon's cock throbbed again, her breasts were really lovely. A good E cup, lovely light pink nipples standing proud on her white, soft scaled chest, and those feminine curves made her a very attractive female. She wore it as well, if not better in some ways than he had.
He suddenly had a very strong urge to explore her body, here in the safe confines of the reserve.
“Guilmon...maybe I should be the one to help you, instead of our tamers? We are the ones who swapped genders after all, so we should help each other," Renamon said, trying to keep his own interests vague.
“Oh, how do we do that? I mean it's not like we can digivolve the same as with our tamers though…"
“Well, I was thinking of a different type of fusion Guilmon, if you will trust me? I am sure you will enjoy it," Renamon said, a sly smile running his muzzle as his cock throbbed again. Who knew that as a male he'd be so horny?
“Well, I do trust you Renamon. You are my friend and we have saved the world together before, so yeah!" Guilmon said with that innocent smile, seeming all the cuter on her slender, more angled face as her tail wagged gently behind her.
“Yes we did, you know you can rely on me," he said in a low, husky whisper, stepping towards her. “And don't worry, no one will know we are here," he said, stepping up close to Guilmon.
“Wh-why should I need to worry about others?" she stammered out, suddenly unsure of his interests, taking a step back only to trip over a root, ending with her rump in the air and legs spread wide.
The sight of her light, pink pussy, so open and vulnerable made Renamon's cock twitch again, a dribble of pre forming against his cock tip.
“Don't worry about that," he said softly, kneeling over Guilmon's splayed form.
“R-Renamon?" She gasped, lifting her head up only to find his muzzle suddenly on her muzzle.
“Muuurrgghhh?!" Guilmon grunted out into the kiss, the first she had ever had in her life. Her limbs thrashed about, her body tried to slide away at the alien sensation; Renamon, keeping a firm lock around her hips with his powerful thighs, relished in her struggles. The more she struggled, the more his cock brushed against her soft, plump pussy and the more she would feel those soft breasts press into his thick fur, feeling the nipples harden and rake across his chest.
Angling his muzzle, Renamon adjusted the kiss, and with some encouragement, managed to lock their muzzles together.
Yellow eyes going wide, Guilmon's struggles grew less frantic and instead, found herself arching upwards into his caresses and reciprocate as an alien sensation crept over her body.
“Mmph," Guilmon mumbled into the kiss, wanting to talk.
Pulling his muzzle off of her's, Guilmon's tongue lolled out dog like, panting cutely as she tried to regain her breath.
“What...was that Renamon? She moaned, eyes drooping as her body warmed up to a pleasurable heat at her core, “and why do I feel tingly all over?"
“That Guilmon," Renamon said as he slowly slipped down her body, those deep blue eyes never leaving that cute face of hers, “was called a kiss."
“And...why did you k-kiss, ahh!" Guilmon's question was interrupted when Renamon wrapped his muzzle around her pink nipple, getting a good bit of flesh with it and sucked hard.
“Because Guilmon...I find you quite attractive like this I will admit," Renamon admitted before going to her other bust, running his tongue back and forth across the nipple, enjoying watching her squirm at the shocks it sent through her body. Giving the bust the same treatment, he spent more time as the kitsune rolled the nipple in his muzzle, massaging the other bust.
“Ah, ahh, Renamon that feels so much better than a belly rub," she moaned, her legs spreading as her smooth crotch glistened with her juices. “R-Renamon, what is happening to me…?" Guilmon's voice turned into a high squeak as he gently bit the fat nipple, sending a shock of pleasure running through her body. Her hips arched powerfully into the air in a cry of pleasure as an alien need began to fog her still new senses,
“It is called needing a mate, something you never explored as a male, but I will be happy to fill that role," Renamon huffed in a lust filled voice, his own cock raging hard and having to keep his hips lifted to avoid dragging his sizable cock in the dirt.
“Mate? D-don't I already have a few mates? Like Takato, Rika and you?" she panted out in her child-like innocence.
“Not that kind of mate, one who can...do things for you, like this," Renamon's deep voice had grown into a type of feral growl as he bent down, pressing his head between her red thighs.
“R-Renamon, that's kinda gross putting your head th…!" any other word of protest was lost when Renamon's tongue dove into her slick passage.
That tingling sensation Guilmon was feeling, became an inferno.
“R-R-Renamon! That feels so good! K-keep licking, it feels so niiiice!" she just about mewled out, her hips thrusting into Renamon's eager tongue as the changed kitsune gladly had his way with her, licking deeper and harder each time, savouring her spicy tasting juices.
Guilmon would thrust upwards with every touch, giving cute, high squeaks as her pussy flowed like a faucet.
“Haah! Ahh!" She squeaked and thrust into her muzzle, only to be greeted by empty air.
“Renamon?" she panted, a note of disappointment in her voice, shivering as a gentle breeze played across her wet mound.
“You think I am just going to leave it at a taste Guilmon?" Renamon growled lowly, his member was throbbing hard and desperately needed some attention paid to it.
“R-Renamon, I'm not sure I want to," Guilmon started to protest, but Renamon was hearing none of it. Thrusting his cock into her muzzle mid-excuse, she tried to pull back and gag, only for Renamon's strong and lithe paws to keep a tight hold around her.
“Mmmgrllrrghh?!" Guilmon grunted around, only to be met by gentle thrusts in her maw, the taste of his salty pre coated her tongue and strangely, she found herself enjoying the flavour. She even found her paw wandering down to massage at her soft, supple chest, squeezing in delight every time she swallowed a load of his pre.
Her tongue wrapped around his cock, helping to squeeze around the length along with her own hot muzzle as she got more and more into the taste, bobbing her head and growing used to the weight and feel of him in her muzzle. The more she drank though the more her pussy throbbed, and the more heated and foggy her mind felt.
Sitting up to cough, she let the last few drops of pre run down to spatter onto the dirt floor.
“Renamon...you taste so amazing, but G-Guilmon feel funny, like hungry but something needs to go inside me below," she said in hot, needy breaths.
His eyes scanning downwards, towards her soaked thighs, Renamon lost all restraint. She smelled incredible and the sight of her juices running down her legs would be enough for any male to lose control.
Pushing her over with a surprised squeak, she lifted her head up only to be pulled flat on her back again as Renamon hooked her arms around her legs and pulled her sharply towards his cock, spearing the red Digimon right through her sodden folds.
“Ahh! Re-Ren-A-MOOOON!" Guilmon cried out as pleasure exploded from her core, the feeling of his large, fox penis deep in her had her form a bridge on the ground, her claws raking and digging up the dirt.
“Of fuck! Guilmon...y-you feel incredible!" Renamon grunted in his deep voice, pulling his hips back and thrusting again and again with wet, lewd squelches. The sensation was so alien to both of them, but so welcome! Jolts of pleasure would shoot up Renamon's cock, Guilmon would squeak or moan with every thrust, her walls clenching around the tool inside her as heat blossomed in her core.
“Renamon, this feels incredible! Harder!" she moaned out, her spread pussy drooling around his cock, squelching louder with each thrust as she felt his knot pound against her entrance.
“D-don't blame me if I hurt you then!" Renamon grunted, smirking at this new side to her before, tightening his grip around her thighs, hammered his cock in hard and deep, causing her shapely rear to jiggle and thighs to vibrate with each forward motion.
“Haah, haah, aahh, RENAMON!" Guilmon cried out, arching into him as her pussy walls rippled and her hungry depths swallowed the knot as she came to climax.
“Oh fuck Guilmon!" Renamon gasped out, his eyes flying wide before leaning over her, squeezing his eyes tight as he came to climax himself.
Taking a nipple into his muzzle, he suckled hard on her hard tit as he gave, short, sharp humps into her wet, warm tunnel, filling her up full with his data seed.
Wrapping her strong legs round Renamon, Guilmon rode him for all she had, loving the attention to her nipple as it heightened the pleasure as she milked him hungrily for all he had.
Eventually both their motions slowed down, and Renamon gave a few last spurts into Guilmon's depths before holding still, softening slowly inside of the female Digimon.
Craning her head up, her thick tongue snaked out to run along his long ear, “That was wonderful Renamon, I hope we can do it often," she said in a husky, breathy moan sounding both adorable and sexy.
“Definitely Guilmon, this change seems to have been for the better. You're...your sweet Guilmon, and I can appreciate you for the first time I feel...Guilmon?" he said as a snore sounded from her.
Grabbing her head, she shook her, only to receive a few grunts before her head lolled again to the side.
“You're still you huh Guilmon?" Renamon smiled with a shake of his head, wincing as the last of his cock pulled out and retreated into his sheath.
Using his teleport ability, he warped them back to Takato's house, laying her down on the sofa. “I don't think gender is the issue why we can no longer evolve with our tamers, it's getting comfortable with our changed forms," he whispered.
Hearing footsteps approaching, Renamon jumped and clung to the corners of the ceiling as Takato walked through, “Well this is great. Guilmon is with Rika and Renamon has vanished, what am I supposed to...do?" he trailed off when he saw the naked, slumbering form of Guilmon on the sofa, her pussy leaking a heavy mixture of seed and her own juices.
His pants immediately tented and made a move towards her, only for Renamon to come down on him and wrap a paw around his mouth.
“Focus on becoming one with her again, don't let your dick guide you, and treat her with respect. Got it Takato?" Renamon hissed into his ear, the poor teen's face going white at the implied threat.
“Ahh, okay I get it!" he gasped when he released him, letting Takato get his breath as he panted before blushing, staring at her before feeling his face go beet red. “So, did you two…?" he started, turning round to where she had been, only to find his device placed on the nearby table and Renamon nowhere to be seen. “Figures," he smiled and shook his head.
Turning back to her, he sighed, “Become one again with her huh...but, she's a girl now," he sighed to himself.
“Takatomon…" Guilmon squeaked gently, slightly opening up a watery, yellow eye, “do you hate me so much as a girl?"
Hearing her sniff tore his heart before wrapping his arms around her thick neck and held her close, doing his best to avoid her breasts and messy crotch.
“No Guilmon, I don't hate you. We'll find a way somehow to make this work, I promise."
*
A few weeks later, Renamon and Guilmon did some group training together with Rika and Takato, helping work them through bonding and growing with their changed partners until they could evolve to their Champion forms, then their Ultimate forms though both sported some changes, though Guilmon more than Renamon. When you see an armoured dinosaur with giant breast cannons, it leaves an impression.
They were working on fusing though progress had been slow; it was only after Renamon and Rika decided they needed to become more intimate with their partners did they overcome some barriers.
And the four of them became much closer than they ever had before, and as a result, much stronger!
