“Ohhh, why isn’t it working?” Bernadetta whined in frustration. Another little spark flickered out from her outstretched hand and fell pitifully to the floor less than a meter ahead of her. Only a little light was released into the dark training grounds late at night. “Stupid Bernie, you’re never going to learn magic…” The shy girl chided herself.

“Don’t worry Bernadetta, it’s alright.” Ingrid, who had been watching her, said from behind.

“EEEEK!!” She shrieked and spun to face the intruder. “Assassin! Bears! Assassin bears!?”

“Woah, it’s only me, ok? No assassins or bears here, promise.” Ingrid stepped forward into the open training ground to greet her comrade in arms.

“I-Ingrid!? Don’t scare me like that! What are you even doing here this late? And… h-how long have you been there watching me?”

“Oh Bernadetta, I was the one who convinced you to join me for some training to begin with.” She explained with a facepalm.

“Wh-what? But how did you know I’d be here now? I wanted to come here alone so I could say I technically trained like you wanted me to, j-just without you watching! I-I mean… ehehehe…”

“Um, you told me you’d be here at this hour? I swear, sometimes it’s like you don’t even know you’re saying things out loud…”

“I did!? Oh no, j-just, er, just forget what you saw! Forget I was ever even here at all!” Bernie spoke hastily as she scrambled to collect her magical texts she had sprawled out on the ground.

Ingrid glanced down at the rather absurd collection of books Bernadetta had before her. She didn’t need to know the ins and outs of magic to understand that the shy woman was trying too much all at once, even after only minutes spent observing her. “Maybe you should go ask for some help from one of the magic wielders in our party. Dorothea knows her stuff, and I bet she’d be willing to give you some lessons.”

“NO! E-er, n-no, I just, um, d-don’t want to waste everyone’s time… Th-there is a war on, you know…” Bernie’s face flushed red. Ingrid saw right through the diversion from her introversion.

“Why are you even learning magic to begin with? You’re already an excellent shot with a bow.”

“I, um… It doesn’t matter…” Bernie dropped her voice. “You don’t need to know I secretly want to be more like Dorothea… Pretty… Confident… Friendly… And so magical!”

Ingrid pretended, for Bernie’s sake, that she hadn’t heard that last sentence. “Trying to learn magic like this is dangerous. If you won’t go to someone for help, I’ll just have to ask someone to help you myself.” She said firmly, trying her best to protect the vulnerable sniper from hurting herself.

“Wh-what!? N-n-no! I’m fine! See, I can cast magic, um, j-just fine! Just like this!” Bernadetta stammered and hastily outstretched her hand, dropping half her books in the process. Her body moved faster than her mind, beginning to cast a spell without actually deciding what to cast. A dozen kinds of spells she had read about all blurred together in her head, causing an ethereal spectrum of lights to erupt from her palm in a display bright enough to drown out the detail in the world around them.

Then, as soon as it had begun, it was over. Both ladies simply stood there in disbelief for a moment before Ingrid broke the silence. “I… have never seen anything like that before in my life. Are you alright? You’re not hurt, are you?”

“I feel really w-werid…” Bernie moaned, crouching forward and holding her stomach. “Oh Goddess this f-feels so weird! Nnng, wh-what’s happening to me!?”

“Calm down, ok Bernie? It’ll be alright, we just have to go see Professor Manuela and-”

“aaaaaaAAAAAHH!!! I feel something pushing out from inside me!!” Bernadetta flailed her arms as she began aimlessly running around the training grounds.

“Woah, B-Bernadetta! Bernadetta!! Bernie!!! Stop moving, I can help!” Ingrid ran after her, quickly catching her and holding her in place. “It’ll be alright, we just have to get you to the infirmary.”

“Th-the infirmary!? Am I gonna die!? N-no, you can’t make me- Ah, AAAH!! Pressure! So much- Nnng!! -pressure!!”

To Ingrid’s shock, she could feel two growing lumps pushing out from Bernadetta’s torso. She released the grasp she held under the sniper’s arms, and what she saw made her heart jump: two new protrusions were jutting out from beneath her existing arms, pushing her strained shirt to its limits.

“What in the name of the Goddess?” Ingrid muttered quietly.

“What is it!? Am I dying!? I’m dying, aren’t I-aieeeeeEEE!!” The fabric of her top finally tore apart, making Bernie lose her balance and topple onto her back. Her entire upper body was now exposed, revealing two new breasts forming under her two original ones - which were now also beginning to expand. “Aaaahh!! Aaaahh!! Nnng… A-ahhh…” Cries of terror slowly warped into moans of pleasure as her failed spell reshaped her body into a foreign, inhuman form.

“You’re not dying, everything will be fine, I promise. That being said, we really should get you to see Professor Manuela- Nnng, rrrrrgh!!” The knight from Faerghus tried picking up her terrified comrade, but to her shock, found she couldn’t lift her very far off the ground and had to set her down again. “What the-!? Are you getting heavier…” Ingrid wondered aloud, but then realised she too was feeling a bit odd inside - almost like a tingling in the pit of her stomach. “...or am I getting weaker?”

“D-don’t let go… Mmm… Nnng… I’m s-scared…” Bernie whimpered between groans. “Ah… H-hold me…”

It was rather uncharacteristic for Bernadetta to ask for physical contact, which made Ingrid raise her eyebrows. Perhaps that spell was causing more insidious effects on the poor girl than were immediately obvious.

Though Ingrid usually wasn’t too fond of intimate contact either, she felt compelled to do as her changing friend asked. Besides, doing whatever she could to comfort people was a knight’s duty. As such, she leaned in closer and gave Bernadetta a reassuring hug.

“Nnng… Mmm, you’re s-so warm…” Bernie said gently as her tears ran dry. She wrapped her original pair of arms around Ingrid, then soon followed that up with her new pair of arms just as they finished growing in. Their hug grew tighter and tighter, not because either of them were squeezing harder, but because Bernadetta’s chest was swelling to an ever greater volume, trying to push them apart.

Ingrid had to withdraw a little, taken aback by her companion’s rapid growth. All she could focus on were both pairs of beautiful tiddies gently expanding with each passing moment.

“Hehehe, like what you see, Ingrid?” Bernie’s voice had taken on a bit of a sultry tone, completely taking Ingrid aback.

“Y-you sound so confident now! Are you sure you’re alright?”

Ingrid’s eyes rose to Bernadetta’s face just in time to see her little smirk grow into a big smile - a smile that revealed inhumanly sharp teeth. “I’ve never felt better! I feel so wonderful now… Mmm, my body is finally starting to feel right…” Bernie kept her upper arms holding the knight ahead of her while her lower arms began to explore her still-shifting body.

As she fondled her new set of boobs, Bernie’s face began to stretch out slightly to form a sharp, shark-like snout. She then let go of Ingrid and got to her feet, allowing new growths to form behind her. A new protrusion was growing between her shoulder blades, forming a menacing dorsal fin. A whole new appendage was pushing out from her tailbone, and it was only a matter of moments before her legwear and smallclothes were torn to pieces, leaving her stark naked.

It was then that Ingrid realised Bernie was towering over her. “W-woah…” She muttered under her breath.

Next to change was Bernadetta’s skin: blue splotches had appeared all over her body and were rapidly spreading to every nook and crevice. Beyond just its colour, her skin was much shinier and smoother now. Finally, a huge, thick, powerful shark tail had finished growing in and was gently swaying from side to side.

The newly formed shark lady was quite the sight to behold. Ingrid struggled not to get lost in Bernadetta’s beauty, but she had a duty to fulfil. “You really should get to the infirmary now. I’m sure Professor Manuela will be able to turn you back.”

“I’m not going back, I’m fine as I am now. No, I’m more than fine, I feel incredible~” Bernie was looking at Ingrid with a spark in her eyes never before seen. “It would be a tragedy if I had to go back to being timid little Bernie-Bear… Then who would you look to with such a lusty gaze~”

It would be unfortunate if she never got to see Bernie like this again… Wait, lusty gaze? Surely Ingrid hadn’t been that enticed by her comrade’s new body, right? “I… I suppose… But your wellbeing is what matters here.”

“And I’m better than ever! Don’t you worry about me, honey, it’s you we need to take care of.” Bernie said matter-of-factly.

“M-me?”

“Why of course, you don’t look so well.”

Now that Bernadetta mentioned it, Ingrid did feel rather off. She couldn’t place it, but it was starting to feel like her body wasn’t quite right despite it being unaffected by the errant spell… She was unaffected, right? Of course she wasn’t affected. Ingrid gave her head a little shake. “I… I can get checked out too when we go to the infirmary. P-please, Bernadetta, we need to-”

“Shhh, it’s ok Ingrid, there’s no need to worry. I’m right here for you.”

“Y-you are?”

“That’s right. You’re so cute when you’re timid and confused, hehehe~” Even Bernie’s giggling was steeped in sultry undertones now.

Ingrid blushed profusely at being called cute. Normally she would have scoffed at being called anything like that, but for some reason she felt butterflies in her stomach that just made her want to hide her face. What was happening to her? This wasn’t normal, was it? What was she even thinking about before, anyway? It was important… or so she thought. Maybe. She was beginning to think she should follow Bernadetta’s lead since she didn’t really know what had even happened.

“It’s alright Ingrid, I’m here for you. I know you like to eye up my magnificent tits whenever you can, so you can give them a squeeze if you’d like~” Bernie said with a wink, then lowered her voice to a whisper. “I know you’ve had feelings for me for quite some time~”

As she pressed her hands to her face in shame, Ingrid couldn’t help but sneak another glance at her crush’s incredible breasts between parted fingers. And, wait… crush!? Feelings!? Ingrid didn’t have a crush on Bernadetta, did she? Everything was such a blur, but she supposed that was how it always felt around such a commanding presence like Bernie’s.

“It’s ok to be shy…” The shark lady cooed, gently grasping Ingrid by the wrists and guiding her hands onto her weighty boobs. “...because I’m here to take care of you~”

The knight shuffled closer to Bernadetta, feeling the comfort of being closer to her crush. Thoughts of curling up in bed with her flooded Ingrid’s mind, filling her with warmth and a desperate longing to be protected and cherished. “Nnng…” She moaned softly as Bernie’s second pair of arms pulled her even closer.

“That’s it… You poor thing, I know how pent up you are. It’s alright, I can help with that~” Bernie lovingly showered Ingrid in headpats.

It was only then that Ingrid noticed her damp panties, which were only growing wetter and wetter. Looking at her crush made the knight’s body go limp as it flooded with lust. Bernadetta was right, she was pretty pent up right now… B-but Ingrid couldn’t let Bernie see her naked! Just the thought made her long-held insecurities rise up and grab her heart like a vise. Wait… She wasn’t normally this insecure, was she? Something felt off… But the familiar shyness stirring within - and the tiddies pressing up against her - chased those confusing thoughts away.

“Here, let Mistress Bernie help you out of those tight, constricting clothes~” Bernadetta said.. “That’s it… just relax and be Mistress’ good lil cow, like always~ Hehehe, just let Mistress take such good care of you~”

Ingrid hadn’t realised just how tight her outfit really was, and… were they getting even tighter? If she didn’t know any better, Ingrid would have thought her breasts were expanding now, too. But it wasn't just her chest: her hips felt squeezed, and there was a strong pressure in her pubic region as well. But wait!! Cow?? Cow!? “M-moo…” Was that it? Was that all Ingrid had to say for herself? Her cheeks burned as searing embarrassment flooded her nerves.

“Good girl~” Mistress Bernadetta whispered lovingly as she freed Ingrid from her clothed prison. “That’s it… My sweet lil moo moo~”

“M-moo moo!?” Ingrid gingerly glanced up at her Mistress’ face in time to see her bear her ferociously sharp teeth. Despite the power her appearance exuded, Ingrid didn’t feel intimidated in the slightest: to the contrary, she felt safe and protected. Her big, strong Mistress would protect her, she could feel it from the bottom of her udder! Her… udder?? Ingrid was surprisingly unalarmed when she glanced down at her naked body and saw huge, sensitive tiddies and a heavy udder between her legs. And why would she be alarmed, that was how she had always been… right? “D-does that udder really b-belong to moo? I mean, t-to me?”

All this confusion made the poor woman shudder, prompting Bernie to pull her closer again. “Shhh, it’s alright… Mistress has you…” While her lower arms held Ingrid, Bernadetta’s other arms patted her head and tenderly scritched behind her ears.

Before she could begin to comprehend the sensations of having an udder, Ingrid noticed her sense of hearing begin to subtly change and a pressure building in her tailbone. Little did she know that her ears were growing longer and pointier, and that a soft lil tail was growing behind her. Regardless, those new sensations were so darn hard to focus on with her Mistress pampering her with so much loving attention.

“Mmmmooo…” Ingrid nuzzled up closer to her Mistress and melted further into her touch. “Nnng…”

“Hehehe, as much as I love holding you like this, we’ve got to stop for now.” Bernie withdrew from the naked lady before her.

“H-huh?” Ingrid said with a confused, dejected look on her face.

“Oh you poor thing, don’t you worry. I’m not going anywhere, it’s just milking time~” Bernadetta assured her subby lil cow.

At hearing the good news, Ingrid’s cute little cow tail subconsciously began to wag, and her long ears flicked excitedly. “Yay! Mooooo!” Without needing to be told, Ingrid got down on all fours - the perfect milking position.

“Mmmmmm, such an eager lil moo moo, aren’t we?~” Bernie teased, then got down on her back and lifted Ingrid on top of her.

“Moo!!” Ingrid yelped in surprise as she was repositioned over her Mistress.

“That’s a good girl~” Bernadetta giggled a bit. “Hehehe, just relax and enjoy, lil cow~” The dominant shark woman used her top arms to knead Ingrid’s full, heavy boobs. With her bottom pair, she grasped two delicate teats and started to rhythmically squeeze and pump. Fresh, sweet milk squirted onto Bernadetta’s soft tum in burst after burst of ecstasy.

“Moo!! Moo!! Y-yes! P-please Mmmmistress, mmmore! Mmmmooooooooo!~”

At that, Bernie placed a loving kiss on Ingrid’s right nipple and began to suckle the milk pent up in her soft, warm chest.

“Mooooo!~” Ingrid moaned gleefully as she felt sweet, sweet release - at the hands of her Mistress, no less! No arousal had ever felt this good before: it was a full-body euphoria that practically melted her mind. The poor cow knew she needed to be milked daily, but this time, it felt like her first time all over again! Today had been so confusing, but it was all ok now because Mistress was here touching her just right… ‘Mmmmoooooooooo~”

The lil moo moo loved giving her milk to Mistress more than anything. The feeling of Bernadetta’s soft yet strong hands carefully milking her private regions was so delightfully intimate it made her want to moo until she lost her voice! And then there was Mistress’ mouth!! Having Bernie’s mouth pressed to her breast to receive her load of milk made her heart flutter! Mistress Bernadetta was incredibly skilled at making sure her sharp, predatory teeth never so much as scratched the cow girl’s soft flesh, which Ingrid found quite impressive. That was nothing new though - Mistress was the most wonderful and impressive person ever, and she was so happy to be her lil moo moo!

“Mmmm-mmmistress? Is my mmmmilk tasty enough? Nnng, moooo! Am I a good enough cow for you? Am I mmmmaking enough milk for you? Mmmmmmmmmoo?” Ingrid whined, desperate for affirmation from the one she loved most.

To Ingrid’s dismay, Bernie stopped suckling so she could respond to her question - she really didn’t think that part through. “Nnng, my sweet cow, you’re more than enough~” Bernie cooed adoringly. “Your milk is simply divine, and there’s so much of it! Hehehe, you’ve been so pent up, poor lil thing… But it’s ok, Mistress is here now. I’ll take care of everything for you! I love you~”

With that, Bernadetta returned to needily suckling on her cow’s hefty tiddy, eliciting more blissful moos and moans. “M-moo!! I love moo too, Mmmoostress!! Mmmooooooooo!!~”

Ingrid’s teats weren’t all that was leaking: her pussy was sopping wet with the intense arousal that always came with milking time. It was almost as if Bernie had a sixth sense connected to her subby little cow, because just as Ingrid was getting exceptionally horny, she repositioned one of her lower arms away from Ingrid’s udder and onto her hard, excited clitty. Mistress knew just how Ingrid liked to be touched - they did this every day, after all! Despite that, everything felt so magically fresh that Ingrid could have mistaken this for her first time!

“Moo!! Moo!! Y-yes!! M-mmmistress, just like tha-thaaa-!!! Nnng, mmmmoooooooooooo!!~”

The cow was on the cusp of climax, about to erupt with one last burst! Right on cue, the euphoria of her Mistress feeling her up in all the right places sent her over the edge. Her teats squirted powerful pulses of milk out all over her lover, while her breasts did the same. The way Bernadetta’s mouth suckled so greedily as she enjoyed her drink pleased the lil moo moo to no end, giving her immense satisfaction from pleasing her Mistress!

“MOOOOO!! MOOOOO!! MMMMOOOOOOOOO!!~” Ingrid screamed, then fell quiet as her milk reserves ran dry.

“That’s my good girl~” Bernadetta cooed gently. “Now how about we go back to my quarters and get cleaned up, hmm? Then we can snuggle in bed together as long as we want~”

“Y-yes! Ahh, thank you Mmmoostress!”

Ingrid and Bernadetta embraced in a loving hug. Together, they would be Mistress and cow for the rest of their love- and milk- filled days.
