Byleth's New Pet

“There you are! I finally found you!”

Shez was lying on top of a hill overlooking the Monastery, the ground pushing up her large chest. The woman with long, purple hair was looking through a pair of binoculars, the sweeping bang usually covering her right eye currently overlaid on top of the binoculars to provide her full perception. The young mercenary’s heart began to beat faster, for after what felt like an eternity, she had finally set her eyes on her.

The Ashen Demon.

“There’s no way I wouldn’t recognize that face, you can’t fool me with some green hair dye.”

Yeah, it was her all right. There was no mistaking it. Right now, she was standing in the middle of the courtyard with what looked to be a clipboard and a pencil, what exactly she was writing down though, Shez couldn’t be sure. Shez watched as Byleth’s looked left and right multiple times across her surroundings and repeatedly jotted down on her clipboard. After about a minute, Shez watched Byleth continue to write as she walked around the left side of the building behind her, disappearing from her line of sight.

Shez let out a deep sigh. She put her binoculars down, a serious look on her face.

‘After all this time…’

It had been two months since she and her comrades had come into contact with Jeralt’s Mercenaries, two months since the Ashen Demon had killed them all with her blade, two months since she had vowed to avenge them. For two whole months, Shez had worked to locate the Ashen Demon’s whereabouts. Slowly but surely, Shez had meticulously tracked her down like a predator to prey.

And then, finally, she found her, here, at Garreg Mach Monastery. She had heard about this place but had never visited herself. This sure made things more complicated, but nevertheless, Shez wasn’t going to let this stop her. She had to find a way to catch the Ashen Demon alone. Once she did that, she would get her ****.

The vow she had made…she wouldn’t let her comrades’ deaths mean nothing. Their next fight wouldn’t end like the last. She was stronger than before, this time she would-

“Hey there.”

Shez’s head shot to her immediate left, and she froze.

Standing right above her holding a sword was the Ashen Demon herself, a wide smile on her lips.

Shez simply looked at her, eyes wide with shock. She was completely speechless.

WHACK

___________________________________________________________________________________

“Mmmm…mnghh…”

“Rise and shine.”

“Mngh…huh?”

Shez slowly opened her eyes, her blurry vision slowly getting clearer and clearer. After a few seconds, she lifted her heavy head. Her eyes shot wide open; sitting on the edge of a bed was a large bearded man, naked with his hard cock fully out, his rich stench invading her nose, with the Ashen Demon, still clothed, sitting on his lap, her arms lovingly wrapped around his neck.

“So she was just hanging outside the monastery?” Kostas asked

“Yes, Master,” Byleth answered with a smile. “I noticed her spying on me from afar. After I quickly knocked her out, I thought I should bring her to you.”

“Your timing, Byleth, couldn’t be more terrible. I would have expected you of all people to not interrupt me while I’m in the middle of a good time.”

Shez had been so shocked by the sight before her that she hadn’t noticed. Located on the opposite side of the bed were three naked girls entwined together, moans dripping from their lips as they made love to one another. The first had long, blonde hair done into a braid, the second had short, orange hair, and the third was a girl with beautiful, tanned skin and long, purple braided hair; all three girls appeared devoid of reason as if they were solely being pushed along by some unknown ****, driving them to give in to a lustful desire.

“Wha…what is…” Shez muttered.

“I’m so sorry, Master,” Byleth said with a deep frown, unused to displeasing Kostas. “I thought you might find her desirable for your collection. I hope I haven’t angered you.”

With a rare gentle touch, Kostas lifted up Byleth’s chin and looked deeply into her eyes.

“I could never be angry with you. You thought this bitch would make me happy. You were only thinking of me. How could I get mad at that?” Kostas said to his one, truest love.

“Thank you, Master,” Byleth said, her eyes shimmering with gratitude.

Kostas and Byleth leaned in and gave each other a long and passionate kiss. The two melted into their kiss, both enraptured with one another. They each found themselves lost in the taste of the other, forgetting about the bound girl in front of them.

“What…I…I don’t…”

Shez felt like she had been knocked sideways. She had dreamt of getting her **** for so long. The Ashen Demon had consumed her thoughts, the image of that cold, unnerving, blank expression, the blood of her comrades staining her sword and face, having been burned into her brain since that fateful night. She really had looked like some demon from hell. That image haunted her very dreams, serving as the one, single thing pushing her forward.

But this woman right here, hopelessly fawning over this savage like some love-stricken schoolgirl…she couldn’t be further from the one she had met on that dreaded night.

“What…what the fuck is going on?” Shez muttered, her voice shaky.

Kostas and Byleth continued their kiss, the two still moaning as they took in and swallowed more of each other’s spit. Kostas squeezed Byleth’s ass while Byleth lovingly stroked Kostas’ cock, making Shez grimace in disgust. Kostas and Byleth let out a long sigh as the two finally separated. Absolutely turned on by his sexy, green-haired slut, Kostas proceeded to give a long, slow lick up Byleth’s face, causing her to moan.

“MMmmm…”

Pulling Byleth closer, Kostas finally redirected his attention back to Shez as if he were getting back to a menial chore.

“So you said she was just watching you from the top of a hill?”

“Yes, Kostas.”

“Hmm, looks like I’ll have to upgrade the defenses around the perimeter. Thank you for bringing this to my attention, Byleth.”

“Glad I could help,” Byleth said dreamily, running a finger up and down Kostas’ chest.

“Actually, now that I think about it, why was she watching you in the first place?”

“I have no idea, Master.”

Narrowing his gaze at Shez, Kostas asked, “Well, would you care to explain?”

Shez grit her teeth. Being knocked ****, being tied up like this, watching Kostas and this woman acting so vile all while they ignored her, and the pain and anger of her comrades being slaughtered by this woman that she had pent up over the last two months: it all finally came to a head, her emotions boiling over.

“I’M HERE BECAUSE THAT BITCH KILLED MY COMRADES IN COLD BLOOD! THEY WERE GOOD MEN, ALL OF THEM! AND SHE JUST KILLED THEM WITHOUT EVEN A SHRED OF REMORSE! I’LL NEVER FORGET THAT DAY! SINCE THEN, I SWORE I WOULD FIND HER AND KILL HER FOR WHAT SHE’S DONE!”

Nodding his head and stroking his chin, Kostas simply said, “I see.”

Turning his head to Byleth, Kostas asked her, “You remember doing that? You recognize this girl?”

With a dark grin, Byleth slightly chuckled and said, “Not at all.”

And with those three, short words, Shez’s face dropped.

“HAHAHAHAHAHAHA!!!” Kostas bellowed. “THAT’S HILARIOUS! OH, THANK YOU FOR THIS BYLETH! YOU’VE MADE MY FUCKING DAY, HAHAHAHA!”

Tears welled up in Shez’s eyes. That…that day…it had meant everything to her, but she…remembered…none…of it…

Shez’s head dropped, for all she could do was stare at the ground, defeated.

Clinging tighter to Kostas, Byleth said, “So, what are you going to do with her?”

“Hmm…not sure,” Kostas said, examining Shez. “All of the noble girls here have been such high quality. I don’t know if I can go back to playing with trash like this. At least commoner girls like Dorothea and Mercedes have the decency to be extra hot sluts with perfect as fuck bodies. I mean, her rack is pretty good but other than that, I’m not sure she’s even worth my time.”

“Mmm, I have an idea,” Byleth interjected.

Placing her lips close to Kostas’ ear, she spoke seductively.

“I’ll take her.”

“Really,” Kostas smirked, raising one eyebrow.

“Frankly, I always loved what you did to Petra, how you made her your obedient pet. Just thinking about it is so hot. Watching you two, I’ve been wanting one for myself.”

Kostas chuckled.

“I thought you already had Edelgard.”

Byleth smiled.

“Edelgard’s sweet. My adorable little princess. That girl worships the very air that I breathe. What we have is…different. What I want is for someone to grovel before me. I want someone to beg for the chance to worship my feet. I want to punish someone, and I want to get wet watching them enjoy it. And trash like her? She would be perfect.”

“Wow…you’re more sadistic than I thought,” Kostas said, his cock getting harder.

Byleth chuckled and looked seductively into Kostas’ eyes.

“You like that?”

“Very much.”

Kostas and Byleth couldn’t help themselves, their lust for one another taking hold of them, as they indulged in another hot and passionate kiss.

Pulling away from her lips, Kostas said, “Hehe, she’s all yours.”

Finally registering what they were saying, Shez perked her head up.

“Wait, what?”

Byleth moved, allowing Kostas to stand up from his throne. With his eyes focused on Shez and a wide grin on his face, he made slow, heavy steps towards his purple-haired captive.

“No…what are you doing?! Stay away!” Shez exclaimed.

“Hehe, sorry, but when my Byleth wants something, she gets it.”

“No, please! Stop!” Shez exclaimed as Kostas climbed on top of her.

Shez’s cries of protest were meaningless, as Kostas shed her clothes off her body, leaving her completely naked.

“Mmm…” Byleth moaned.

“Hehe, like what you see?” Kostas asked.

“She’s going to be a very fun toy.”

“Hehe, you heard the lady,” Kostas said, his cock about to enter her pussy.

“What are you doing?! Please, don’t!”

Kostas shoved his cock inside of the purple-haired mercenary and immediately began thrusting in and out of her pussy.

“Ahh!! Ahh!! Ahhhh!!” Shez cried out, the pain of Kostas’ thrusts unbearable.

Byleth happily watched as Kostas mindlessly rammed Shez repeatedly with his large cock. His wide, strong body overpowering her smaller, slender frame, god, she was so jealous. Byleth bit her lip, wishing it was her receiving such rough treatment.

Byleth continued to enjoy the show, as Shez got savagely fucked by her Master. She loved seeing her Master happily thrust his cock inside her pussy. She loved seeing his large hands fondle her body, squeezing and pulling at her breasts. She loved hearing Shez’s screams of pain and terror, as well as seeing her eyes begin to roll in the back of her head. Byleth’s grin grew wider upon hearing Shez’s screams begin to slowly transition to moans of pleasure, proof that Kostas’ power was already starting to work its influence over her.

Byleth began rubbing her pussy through her black shorts as she watched this all play out, low moans leaking from her lips.

“Mmm…ahh…”

Soon, this girl would be her brainless slut. Yes, she would make her her obedient, little pet. The things she would do to her…mmm…

“AH! AH! AHH!” Shez cried out in pleasure.

Shez’s cries were now resonating throughout the room, the pleasure having fully enveloped her. Shez’s anguish made Byleth so fucking wet, as she continued to play with herself, her moans also growing increasingly louder.

“MMmmm…ahh…ahhh…”

Hearing Byleth’s moans, Kostas turned back and looked at his sexy, green-haired slut, smiling upon seeing his favorite girl play with herself like the true slut she was. The two locked eyes, only making Byleth even more wet. A silent understanding between them, Kostas turned back around to finish the task at hand. After just a few more seconds, Kostas came inside Shez’s pussy, erasing all that the girl was. Kostas pulled his cock out of Shez, fully revealing to Byleth Shez’s condition.

Her limbs were splayed out, her head on its side with her tongue hanging out and the dumbest, widest smile on her face. Her brains, or at least what little she had, Byleth chuckled to herself, looked like they had been completely emptied, leaving nothing but a broken, mindless slut. Byleth reached under her shorts and slid two fingers inside her slit, moaning at Shez’s hot, pathetic state.

Kostas walked and knelt behind Shez, sitting her up. As Shez’s head went limp, Kostas grabbed a fistful of her bangs and pulled her head up.

“Hehe, that felt good for ya, didn’t it?”

“Yesss, s-soo good, Master,” Shez said, her voice still shaky from the afterglow.

Kostas tugged Shez’s hair tighter, pulling her head back so that his lips were now directly next to her ear.

“Now listen here, trash like you doesn’t get the privilege of calling me that. Maybe I’ll be kind and allow you the honor of sucking my cock from time to time, but other than that, I don’t want your filthy stench near me.”

Kostas tugged at her hair again so that she was now looking straight at Byleth.

“But you see that amazing goddess over there? She will be your Master. You’ll do anything she says. Your every waking moment will be devoted to making her happy. You’ll be her obedient dog. You understand?”

“Ahh, yesss…”

“You better. That woman right there is very important to me. If she ever becomes displeased or bored with you, I’ll fucking kill you myself.”

Shez could only moan in response, her mind only consumed with servitude and pleasure.

Taking that as a suitable response, Kostas tossed her back onto the ground like the trash she was. Shez then immediately began to slowly crawl towards Byleth like a moth pulled towards a flame. Stopping a foot away from Byleth, Shez rested on her knees with that wide, dumb smile still plastered on her face.

Panting heavily from playing with herself, Byleth pulled out her cum-covered fingers, and then with a naughty grin, Byleth ran her fingers down the middle of Shez’s face, leaving a slick trail of her juices. Shez shuddered, her eyes rolling in the back of her head.

Byleth’s smile grew wider, as she opened her legs, silently offering Shez the sweetest gift she could grant. Shez obliged, quickly crawling that last foot and shoving her face into Byleth’s crotch. Byleth moaned in response to Shez’s eager tongue. Byleth gripped Shez’s long hair, pushing her deeper against her crotch. Shez rapidly ran her tongue across Byleth’s crotch, desperately needing to worship the beautiful goddess before her.

Byleth watched the newly tamed Shez **** herself. A few minutes ago, she had loudly declared her attention to kill her, but now, she was absolutely lost in worshipping her crotch. It was so delicious.

Byleth pushed Shez’s head away, causing her to give a disappointed whine. Smiling at Shez, Byleth lowered her shorts and leggings, revealing her bare, wet pussy. Shez’s eyes widened, her jaw having dropped to the floor. Her breath was caught in her throat, the girl practically shaking from the sight of Byleth’s gorgeous pussy. Byleth beckoned her with a curl of a finger, and Shez seized her chance, leaping at Byleth’s wet slit. Shez’s eyes were once more rolling in the back of her head as the taste of Byleth’s pussy filled her mouth.

“Mmmm…ohhh…”

Shez continued to lap her tongue at Byleth’s pussy, falling deeper and deeper into her oral worship.

“Hehehe,” Kostas chuckled. “How is she?”

“Mmmm…hehe, she’s perfect.”

Byleth cupped Shez’s cheek, pulled her back, and looked into her eyes.

“An obedient, little toy.”

“Thank you, Mistress.”

Byleth smiled and shoved Shez’s face back into her pussy.

Kostas himself smiled seeing his Byleth happily moan. He walked past Byleth, leaving her to her fun, and made it towards the bed. He crawled onto his bed, slapping Petra on the ass, before jumping into the middle of the ongoing threesome, hungry to continue what he had started. Kostas and Byleth both lost themselves in their own fun, the room becoming decorated with the warmth of their separate, lust-filled moans…

…the moans of a Master and Mistress relishing in the unconditional and adoring love of their slaves.
