"Aaand there!" Bernadetta sighed, removing pen from paper.

Due to a shortage of Master Seals among the army, Bernie and Petra decided to try advancing to a master class with the same Master Seal. After configuring it to test for the Bow Knight class, the seal had transformed into an exam paper. Both women wrote their answers on the same magical parchment and, when they finished, held their exam aloft.

Though anticipating only one of them to gain the benefits of the Master Seal, they still believed it was worth a try. However, a piercingly bright light erupted from the exam, sending the pair of archers flying backwards in the otherwise-vacant classroom.

"EEEEP!!"

"WOA-WOAH!"

"What… What happened?" Bernie rubbed her head.

"Nnng, Bernadetta, p-please be removing yourself from on top of me!"

It took a moment for Bernadetta to realise she was sitting on her friend's head! "OH NO! Oh now look what you've done, Bernie! Stupid, stupid! Petra will never like you now!"

The flustered introvert tried to get to her feet, but stumbled over almost immediately.

"Bernadetta, your legs are being stuck to my arms!" Petra exclaimed, noticing her skin beginning to melt into Bernie's. Though alarmed, she couldn’t help but notice this situation was turning her on.

Trying more carefully this time, Bernie got to her feet. Petra followed suit, only able to stand while bent forward with her head between Bernadetta’s thighs. And then, Bernie looked down to see her body merging with Petra’s.

“Wh-what!? B-but this… I didn’t think you meant they were literally sticking together! EEEEP!” Bernadetta tried to run away, but found she was no longer in control of her legs. The shy archer flapped her arms up and down as she panicked.

“A-ah! I am having s-strange feelings all over my body…’

The pair’s nervous systems were already intertwining, letting each of them feel the other’s body as if it were their own.

“N-Nnng, neigh! EEP-!!” Bernadetta flung her hands over her mouth.

“Was that a ‘neigh’ I was just hearing?”

“W-well, I mean, I just… Ohhh, Bernie, now Petra thinks you’re weird! Why did you do that!”

“It is alright, I thought your ‘neigh’ was very adorable!”

“R-really!? I-I mean, I’m sorry! I mean…”

“Nnng, why is everything feeling so tight?” Petra groaned.

Both of them were growing rapidly, straining their clothes to their breaking point. Bernie’s once-small, cute breasts were now hefty boobs stretching the material of her dress, and Petra’s entire body was inflating to the size of a horse. Petra’s once-loose fitting Brigid attire snapped and fell to the floor as thin brown horse hairs began to sprout all over her body. Bernadetta yanked her tight, uncomfy clothes off, but immediately regretted doing so once she realised her still-growing tits were exposed.

Looking down on herself, Bernie noticed that Petra’s face was between her legs instead of her genitals. “HUH!? PETRA, WHERE DID MY PUSSY GO!?”

“I believe we are becoming a centa-” Petra was cut off when her mouth sealed over. The rest of her face soon followed suit, leaving a muscley, horse-like chest between their front legs. ‘Bernadetta?’ Petra called out in Bernadetta’s head.

“EEEEK!!” Bernie shrieked at the unexpected second occupant in her head.

‘Do not be worrying, Bernadetta, I am Petra!’

As Petra's consciousness relocated to Bernie's mind, their transformation was nearing completion. A gorgeous tail of violet hair grew from their huge ass, matching that which Petra had on her head mere moments ago. Their four powerful legs gained muscle and fat in their thighs while their feet curled up and solidified into hooves.

Finally, the experience was over, leaving in its wake a six-foot 4-inch tall centaur girl. Petra was able to see through Bernie’s eyes, as well as share the rest of her senses too.

“Why did this happen!? P-Petra what happened to us!?” Bernie squealed nervously. “Nnng!! A-and why am I so horny…” The recluse instinctively slid a hand down to her crotch, but to her dismay, only met with her new horse torso.

‘B-Bernadetta, our body is feeling very good…’ Petra commented, her arousal mounting.

To their shock, they could both sense each other’s thoughts and emotions. Bernie felt that Petra was relishing in such an unusual experience to share a body with a friend. Petra, meanwhile, felt that Bernie was incredibly embarrassed and concerned about how this would affect Petra’s perception of her. And then, they both felt it: their mutual love for each other. They knew instantly that they were both crushing on each other, and that they were both crushing on Dorothea. Both of their thoughts wondered if Dorothea would like their new form…

After a moment to process their new sensations and emotions, Petra broke the silence. ‘I was not knowing you had these feelings for me~’

Usually, Bernie would have cowered away from this topic of conversation out of fear of the unknown - fear of judgement. This time, however, she knew exactly what Petra was thinking and how she felt. To her genuine surprise, there was no malice, no disgust, no dread, and no other ill feelings. She had been conditioned by her abuser that she was so unloveable that nobody could ever harbour a single positive feeling towards her. Yet here they were. Her anxieties had been proven absolutely false… at least in this instance.

“I…” Bernie would have struggled to find the words under normal circumstances, let alone while experiencing such strong libido after being fused and transformed.

‘It is alright, Bernadetta. I know. I am feeling- er, I feel your relief. I will ask you even though I believe I am knowing the answer now, but… would you like me to be your girlfriend?’

“YES!” Bernie blurted before her mind could catch up to her mouth. “P-please… I like you a lot, Petra. I’ve always wanted you to like me… And I’ve always wanted to be a bit more like you.” She nervously fidgeted her arms, mostly out of habit.

‘This pleases me greatly! Though you already knew that, did you not?’

Bernie simply nodded.

“I am feeling like I am on the top of the world! Let us go find Dorothea! We should be asking her to be our girlfriend too!’ Petra said, excitedly turning to the door and carrying them both out to the courtyard.

“W-woah! Petra!! Where are we going!? OHHH, WHY CAN’T WE JUST HIDE IN THE CLASSROOM UNTIL THE PROFESSOR COMES BAAAAAACK!?” Bernie’s arms quivered as she indignantly held them in tension beside herself. She tried to command their legs to halt, but it was no use: Bernie controlled their human half while Petra controlled their horse half.

‘But it is feeling too good to be stopping! A-and besides, walking is giving a little relief on our pussy~’

“Neigh! I mean no! It’s not giving relief, it’s making us hornier!!” Bernadetta blurted, covering her mouth once more as she scanned the courtyard around them - lucky for her, nobody seemed to be in earshot.

After only a few minutes of trotting, the fused centaur had reached the fields just outside the monastery without being seen - much to the relief of Bernadetta. Dorothea had told Petra that morning that she would be outside relaxing under a few nice trees, and lo and behold, the pair arrived to meet Dorothea singing to herself in the trees’ shade.

“P-Petra! Do we have to do this right now!?” Bernie whispered with renewed anxiety at the sight of her other crush.

‘If not now, then when will we be doing it?’

“I don’t know! Just… Just… EEP!!” Bernie squealed as she realised they were now face-to-face with Dorothea.

“Bern? Is that you!?” Dorothea gasped.

“H-hi, D-Dorothea! Um… Yeah, it’s me… Well, and P-Petra, too…”

“Petra?” Dorothea asked.

‘Yes, it is me!’ Petra thought happily, forgetting for a split second that she could no longer speak. ‘Bernadetta, would you please be telling- er, tell Dorothea that I say hello?’

“Petra says hello. Um, well, I should explain… you see, there was a Master Seal and some magic and, uh… We sorta, kinda, m-merged… and turned into a centaur…”

“Wait, so you’re saying that the centaur I’m seeing is both Bern and Petra!?” Dorothea’s jaw dropped, a lusty sparkle flickering in her wide eyes.

“Y-yeah… D-don’t worry, we’re fine! Petra and I are sharing! She’s in my head - our head - and can talk to me. She’s actually pretty excited by this… Oh, and I control the human part of us, and Petra controls the horse part.” Bernie twiddled her fingers as she averted her gaze.

“Hee hee! Well I could have guessed that much, Bern! If you were in control of your feet I know you would be back in your room right now.”

‘Ask if Dorothea would like to be joining us in your room~’

“EEP-!!” Bernie covered her mouth in a split second.

“Hee hee~”

‘Tell her, Bernie!’

“I, er, um, I mean, well, I just, ohhhh why are you doing this to me Petra!?”

Dorothea tried to hold back a giggle.

“W-well… You see…” Bernie took a deep breath before speaking a mile a minute. “Petra and I both have a crush on each other and are dating now and we both have a crush on you and were wondering if maybe you wanted to date us too and head back to my room for, for-!… for… Oh no. Bernie, what were you thinking! She’ll hate you now for sure!”

“Oh Bern… I could never hate you. In fact…” Dorothea slowly stepped towards the centaur and lowered her voice to a sultry tone. “I’d love to be part of a thruple with you two~”

"Ohh, please just forget you heard anything! I promise I won't-" Bernie paused abruptly. "W-wait, did you say… y-yes!?"

"Yes," Dorothea smiled, placing a hand below Bernie's belly button.

Petra excitedly fidgeted their hooves. 'Yay! We are a 'three-couple' now! Invite Dorothea to ride us!'

"Oh, you haven't the slightest idea how long I've wanted to ride you two, Petra~" Dorothea winked playfully.

"Eekpthfafthveep!!" Bernie was so flustered that her voice couldn’t form words.

'Dorothea, you are hearing me?'

"I can hear you whenever you call, darling! It's the magic of love~" Dorothea cooed, then hopped up on the swooning centaur’s back.

Petra immediately set off galloping, causing Bernadetta to yell "W-WOAH! NEIGH!!"

Dorothea nearly lost her balance, but wrapped her arms around Bernie and grabbed on to her soft, plump tits.

"EEEEK!! M-my boobies! My girlfriend is touching my boobies! My other girlfriend is a centaur with me! Is this real? Am I dreaming!? This is the weirdest combination of nightmare and daydream I've ever had!"

The thruple relished in the simple pleasure of running around in a sunny field like there was no tomorrow. Even Bernie, who was flustered to no end, couldn't deny how lovely the wind felt on her skin and through her hair. All three of them had fantasised about going horseback riding together, and they finally got their wish! At least, in a manner of speaking.

The sensation of Dorothea mounted atop their sensitive, exhilarated body only fed the shared libido Petra and Bernie were feeling. Their new pussy was aching for action, and the running motion of their hind legs did nothing to quell that desire.

Dorothea shifted forward, grasping the human part of her two girlfriends in an even tighter hug. "I can feel how horny you are, darlings! Hmm hmm hmmmm~"

Petra gradually slowed to a halt and gently knelt down on the soft grass. 'Oh Dorothea! Please be touching us! We need you!'

"Y-yes! Please Dorothea, we're so h-horny…" Bernie's voice dropped to a mumble as she pressed her index fingers together. Petra and Bernie were unanimous in the emotion that was overwhelming them. "W-we love you so much…"

Once Dorothea dismounted, Petra instinctively began rubbing their thighs together in a hopeless attempt to gain some relief. Their massive butt wiggled and their tail flicked of its own accord in anticipation.

"Hee hee hee! You're so adorable when you squirm like that! Poor thing, you can't reach your little pussy on your own, can you?~" Dorothea sat on her knees by the pair’s hind legs. “Would you like me to help you out?~”

“Yes!” ‘Yes!~’ Bernie and Petra cried in unison. Petra further dropped the front of their horse torso so their ass was sticking up in the air, displaying their dripping pussy for Dorothea.

In response, Dorothea placed a loving hand on each ass cheek and tenderly began kneading their soft glutes. “Beg me for it, darlings~”

“Nnng, oh Dorothea! W-why are you such a tease!? Ohhh, mmm, th-that feels so good, b-but our pussy!!”

‘Ah! Ah! Please do not be stopping! Please Dorothea, be ‘eating us out-’ er, eat us out! We love you!’

“How could I say no to two cuties like you~” The songstress leaned forward, lingering so her lips were centimetres away from their labia. Each breath she took graced the centaur’s sensitive skin, goading her submissive partners.

“D-D-Dorothea!! Ahh! P-please! We need you! Ohh, mmm!”

‘Y-yes! We are needing you very much! Nnng, B-Bernie is right when she is saying you are a tease!’

With that, Dorothea pressed her lips onto her girlfriends' pussy in a wet, loving kiss. She squeezed her partners' butt harder as she pressed her face into their delicate labia lips. Her tongue circled over their adorable little clitty, rubbing and pressing, licking and fondling.

"AAAH! MMM, THAT FEELS SO GOOD! YES! PLEASE, PLEASE, NEVER STOP!"

'NNNG, AHH, OH DOROTHEA, YOU ARE BEING VERY ADEPT AT TH-THIS!! PLEASE CONTINUE FOREVER!'

The adorable cries for more were music to Dorothea's ears. Pussy juice flowed down her face and dripped from her chin, beginning to drench her silky dress. Dorothea was overjoyed that she could please her lovers so thoroughly.

But all good things must come to an end. With a splutter, Bernie and Petra came all over Dorothea's gorgeous face.

'WE ARE COMING!! AHH!'

"NNNG-NEIGH! AAAAHH!"

Finally getting the relief they craved, the centaur slumped over in exhaustion.

"Hee hee! My good girls~" Dorothea shifted over to the front end of their large body, curled up, and rested her head on Bernie's soft tummy. "Good girls… My sweet things, you're such good girls…" She cooed adoringly.

"W-we love you, Dorothea!" Bernadetta quivered, astonished that she had finally gotten intimate with two of her most cherished friends.

'We love you very much~'

"I love you too, darlings~"

With that, the three of them dozed off for a relaxing nap under the midday sun.
