Chapter 37 by JPZone
The first piece of the Golden Deer has fallen! Just who will Kostas set his sights on next? Who is destined to be his next ?
Lysithea Swallows Her Pride
Kostas was at his desk going over his plans. He had set his next sights on someone special:

Lysithea.
Lysithea was a prodigy in the magical arts and had already quickly gained the reputation of being the strongest mage at the monastery. Acquiring someone like her would be an incredible asset. Kostas had powerful slaves like Catherine, Byleth, and Shamir already at his disposal, but Lysithea would serve as the extra power he needed. No one would be able to challenge him.
Having a cute girl like her tending to his cock wouldn’t hurt either.
However, as Kostas knew very well at this point, the greater the reward, the bigger the risk. What made Lysithea special also made her dangerous.
He had to be careful with this one. Knowing her quick-tempered personality, she would be extremely mistrusting. She would be suspicious the second he even glanced her way. One wrong move and it would LITERALLY blow up in his face. He couldn’t lose everything he had worked so hard for, not when he was so close to realizing his plans for the monastery.
His ideas for this place were just too good to give up.
That was when Byleth came up with another approach. And boy, was it a good one.
Kostas smiled at how inspired it was. He had faith in his slut. The plan would work.
Interrupting Kostas’s thoughts, the fucking incredible feeling between his legs just reached new heights, making the bandit groan in satisfaction.
“Hehe, you’ve gotten really good at that,” Kostas said. Looking under his desk, he saw his sexy pet, Petra. The very sight of her made his cock even harder: completely naked aside from the treasured collar he had given her, her lips wrapped around his member, and the affectionate way she looked at him as if he were the only thing of importance. Just like a good pet should.
Kostas pet her head, loving just how fucking sexy she was. Nowadays, the Brigid princess rarely left his side. Many long nights spent strategizing and planning were always enjoyable thanks to Petra being there to tend to his every need. Her exotic body was the perfect toy to play with. Among the many things he cherished, Petra was close to his heart.
Kostas grabbed Petra’s braid and pulled her off of his cock, her wet lips making an audible pop. He caressed her cheek, his thumb tracing the purple mark beneath her eye, “You’re a great cocksucker, my pet.”
“Thank you, Master,” Petra responded happily, panting with her tongue out. Kostas had taught his pet how to properly address her Master. “I am loving giving you joy, Master! How else may I be serving?”
God, he loved the way she spoke. It made him so turned on.
He should probably go over his plans one more time…but it could wait.
How could he say no to that face?
Kostas chuckled, “Let me see that sweet ass of yours. I want to hear you scream my name.”
_____________________________________________________________________________
Lysithea was quickly walking down the grounds of the monastery, coming back from some intensive studying. From the second she woke up at dawn, her long day had been filled with various tasks: battle tactics, skirmishes, choir practice, visiting Professor Hanneman’s office hours, and advanced magic training.
It was so much work, but it was still wasn’t enough. She had to do more. She had to improve and get better as fast as she could. In fact, while visiting Hanneman’s office hours, she requested that he allow her to start authority training so she could lead battalions on the battlefield. It would give her plenty of the skills she still needed.
It seemed like there just weren’t enough hours in the day.
After a nonstop day, Lysithea was heading to her room for a quick break. Hilda had warned Lysithea that it wouldn’t do her any good to push herself till she dropped, and even though she didn’t want to hear it…Hilda had a point.
But after a quick rest, she had to head over to the training grounds and practice some light magic before dinner. Dark magic was her specialty, but she figured that she should at least learn the fundamentals of light magic to gain a more well-rounded knowledge of the magical arts.
But for now, rest.
Reaching her room, Lysithea entered and closed the door behind her. As she went over to put her things down, the first thing she noticed was a piece of cake on her desk. It was a cute, strawberry shortcake with whipped cream and a single strawberry on top. Next to the cake was a folded note with her name on it. Intrigued, Lysithea picked up the note and opened it:
Dear Lysithea,
I saw that you’ve been running around the monastery all day. It looks like you’re working hard! I know you love sweets so I thought I would surprise you! Just a little reward for you giving your best!
From, Your Friend,
Leonie
Lysithea smiled brightly; she would have to thank Leonie later. Not letting her friend’s gift go to waste, Lysithea grabbed the fork and took a bite out of the cake. It was amazing! The cake was an explosion of sweetness, as it practically melted in Lysithea’s mouth. The very taste gave Lysithea the biggest grin. The delicious vanilla, the sweet strawberries, and the thick whipped cream. Within a minute, the cake was completely gone.
Lysithea sat on her bed, relishing just how delicious that cake was. “Ah, that was so good!” After Lysithea took a moment to herself, she looked at the time and realized that she was behind schedule. “Oh! I have to go!” Lysithea dashed out of her room, only to run into someone that was walking by.
“Woah! Hey, you should really be careful about where you’re going.”
Completely flustered, Lysithea exclaimed, “Oh, I-I’m so sorry. I didn’t mean to-” Lysithea looked up and saw that she had bumped into a large man with a beard, a big nose, messed up teeth, and smelly breath. Actually, now that she collected herself, she realized that this guy stank. She was tempted to pinch her nose right in front of him.
“It’s all right. No harm done,” Kostas said. Kostas scanned the area around him, “It looks like you’re lost. Are your parents around?”
Immediately triggering one of her buttons, Lysithea glared angrily at Kostas. “What is THAT supposed to mean?! I am a STUDENT!!!”
Noticing Lysithea’s uniform, Kostas had a look of surprise, “Oh, forgive my mistake. I didn’t know they let children become students.”
Pushing her button again, Lysithea was quickly becoming irritated, “EXCUSE ME?!?! I am 18! And I’ll have you know that I am a VERY gifted mage! I am not a child!”
Kostas smirked, crossing his arms, “Oh, really?”
“Yes, really!” Lysithea’s anger was beginning to cloud her thoughts.
This was Byleth’s plan.
Lysithea was very suspicious so there was no tricking Lysithea. On top of being very suspicious, however, she was also very prideful.
So instead, he would play into that. If you couldn’t trap the bear by outsmarting it, then you had to poke it hard with a stick, making it so the bear ran into your trap headfirst.
By exploiting her short temper, Lysithea would give in to her emotions, making it so that she would stop thinking rationally. By doing this, she was unknowingly creating an opening for Kostas’s crest, allowing the crest to worm its way further into her mind.
This was only possible due to Lysithea’s second weakness: sweets.
He knew she couldn’t resist something as simple as sweets. Using her favorite thing in the world against her was an all too simple plan of attack, but all too effective.
Putting my cum into the cake? Hahaha, what a great plan indeed.
And because of that, soon her stupid pride would lead to her downfall.
He just needed to get her on the hook.
“Just because you’re 18 doesn’t mean you’re an adult,” Kostas said patronizingly, “The fact that you have to say you’re an adult proves that you aren’t one. Experience makes you an adult, and it’s very clear that you don’t have any.”
“Don’t patronize me! I can do anything an adult can!”
Hehe, and there it is.
And now to reel her in.
“Anything?” Kostas asked.
“Anything!” Lysithea answered back. She already hated this guy. He looked at her the same way most of the people here at the monastery did. Like she was a child. Like she couldn’t do anything on her own.
“Hmmm…” Kostas said, placing his hand on his chin as if deep in thought. “Oh, I know,” Kostas leaned forward, causing Lysithea to lean back slightly, “How ‘bout a blowjob?”
“What?!?!” Lysithea said in shock, slightly blushing, “Who the hell do you think you are?!?!”
“What’s the problem? You did say anything,” Kostas smirked. “Besides, lots of girls your age give them. They’re pretty good at it too.”
Lysithea was getting a nagging feeling in her mind. She should go see Rh-
“Looks like I was right,” Kostas said boastfully, “I guess you are just a little kid after all.”
Lysithea’s anger surged at those words, instantly pushing that nagging feeling aside. Her face turned red as she yelled at Kostas, “THAT’S. IT! YOU WANT ME TO PROVE I’M AN ADULT?! FINE! MY ROOM IS RIGHT HERE! I’LL SHOW YOU!”
A grin grew on Kostas’s face. Too easy. Like taking candy from a baby.
Lysithea had taken the bait, her emotions had gotten the better of her. With that outburst, Kostas’s crest had an ample opening to latch onto her mind. That nagging voice wouldn’t be a problem anymore; the power of the crest having enough power to completely snuff it out for the time being. Just enough time for Kostas to claim another ****.
Very much annoyed, Lysithea opened the door to her dorm, allowing Kostas to walk inside. Closing the door behind them, Lysithea glared at Kostas with an intense determination.
Kostas couldn’t help but be amused at the young girl’s attitude. She was on the edge. She just needed a little push to begin her descent. But from here on out, Kostas knew EXACTLY what to do.
Kostas dropped his pants to the ground, revealing his large cock to the young mage. Despite her bravado, Lysithea stood there for a moment simply staring at Kostas’s cock, unsure of what to do.
“Are you chickening out? Hehe, there’s no shame in it. If you’re afraid, I ca-”
“I’m not afraid!” Lysithea yelled. Her anger pushing her forward again, Lysithea kneeled in front of Kostas. She would prove to him, to everyone, that she wasn’t a child. Despite this, Lysithea hesitated at the intense odor of Kostas’s cock, as it made her head spin. She inspected his cock, as she had never gotten such a close look at one before. Her heart was beating faster, but she pushed past her initial apprehension and gave Kostas’s cock a long lick.
Ugh, so gross! Lysithea hesitated again, not expecting it to have that particular taste. Despite her hesitation, however, Lysithea licked Kostas’s cock again. And again. And again. And again. With each lick, Lysithea grew less nervous and grew unnaturally more confident. Her hesitancy was fading away very quickly, as Lysithea focused intensely on the task at hand.
“Ohhhhhhh….” Kostas groaned.
Suddenly, Kostas’s cock twitched, breaking her concentration. She flinched back, as Kostas’s cock got harder and began to grow longer. Her eyes widening, Lysithea yelped in surprise.
Kostas let out a loud laugh at Lysithea’s reaction, “I guess you really are new at this. Hehehe, don’t be scared. That means it likes it. Go on, keep going. But if you REALLY want to do it like an adult, you need to wrap your lips around it.”
Oh yeah?! Watch this, you jerk! Lysithea did as Kostas said and wrapped her lips around Kostas’s cock. She bobbed up and down his cock, the full, potent taste of his erect member filling her mouth, but even that she was quickly getting used to.
Kostas looked down and smirked at the young girl pleasing his cock, “Cmon, now. You can do better than that! Aren’t you supposed to be some sort of prodigy? Maybe everyone was wrong about you, but what should I expect from young, little Lysithea?”
Lysithea sent Kostas a piercing glare, as Kostas struck an especially raw nerve that time. Her anger blinded her, as she went up and down his cock even faster. It didn’t even hit her that Kostas shouldn’t know those things about her, especially her name. Lysithea was too busy putting all her effort into sucking Kostas’s cock. Lysithea’s cocksucking was sloppy, but she was eagerly working her hardest, rapidly moving her tongue around his member.
Kostas was so fucking aroused. The girl he had been so worried about was aggressively sucking his cock. There was never any reason for concern.
She never stood a chance.
Kostas grew a sadistic grin; he wasn’t going to hold back.
This was going to be good.
Kostas forcefully unloaded his cum right down Lysithea’s throat. Lysithea’s eyes widened, as she wasn’t the slightest bit ready for it. She reflexively swallowed, as her throat became flooded with his semen. After the initial shock, Lysithea pulled her lips off his cock, gagging and **** on the leftover cum in her mouth. Lysithea looked up only to wince as Kostas’s cock continued to shoot white strings of cum onto Lysithea’s face, matching well with her white hair and pale complexion.
With warm strings of cum on her face, Lysithea sat there on the ground in a daze with her mouth slightly agape, looking as if she were overwhelmed by it all. Her mind was running at a million miles a minute. Something was changing in her. Ingesting that large amount of Kostas’s cum made the crest’s effects even stronger, as it now had a much tighter hold over her.
Kostas was unaware of it, but after his many conquests, Kostas’s crest was growing stronger. It was making the beginning stages of its metamorphosis, altering and changing itself. Kostas’s crest almost had a mind of its own, following the will of its owner. To carry out Kostas’s plans, the crest knew it had to evolve and adapt, and right now, Lysithea was experiencing the growth of that power. It was enveloping her mind, applying its power to seamlessly break through her defenses.
Lysithea, also unaware of this, was unable to properly process the sensations she felt. A warm current enveloped her from her head to her toes. While taken aback at first, the warmth of his cum felt…soothing. Her heart rate slowed, as she started to feel an odd calmness wash over her. She grew more and more sedate until she was blankly staring ahead, her eyes cloudy.
Kostas chuckled seeing the young girl’s face go lax, “How do you feel?”
“H-huh?” Lysithea said, her cloudy eyes looking towards Kostas.
Cupping her chin, Kostas asked Lysithea again, “I SAID, how do you feel?”
“I…I feel…..” Lysithea mumbled.
“HAHAHAHA! That’s it, huh?! Not shooting off your mouth anymore?! HAHAHAHAHA!” Kostas put his cock right in front of Lysithea’s lips, who automatically wrapped her lips around it and began to suck in a slow rhythm. Without any resistance, she swallowed Kostas’s leftover cum, further tightening his control over her. As more of his warm cum fell down her throat, she felt a warm, pleasant tingle in her brain.
Kostas softly stroked her hair like a proud parent showing affection to their child.
“Hehe, very good.”
Having sucked his cock clean, Kostas pulled Lysithea off of his member. Rubbing his thumb across her chin, he asked, “Hehe, how ‘bout I fuck you on your own bed?”
Her face still blank, Lysithea subtly nodded her head. Kostas picked Lysithea off the ground and tossed her onto her bed. Kostas reached under the girl’s skirt and lowered her white panties, tossing them aside. He pushed his massive cock inside her body, stretching the walls of her pussy. The pain from the sheer size of his cock took Lysithea out of her docile state, as she let out a sharp scream.
Kostas laughed, as he forcefully pounded her repeatedly. She gave him an attitude? She wanted to be an adult? He would show this brat a lesson. Kostas took great joy in feeling his cock go up deep inside her pussy. The tightness of her pussy was incredible, as he could feel Lysithea’s walls clench around his cock. Virgins really were the best.
The pain tore through Lysithea, each passing thrust bringing about wave after wave. Yet after a while, pleasure started to accompany the pain. With each thrust, the pleasure grew more and more until the pain and pleasure were intermixed perfectly together. Lysithea’s body was on fire, as the sensations she felt were utterly consuming her. Lysithea couldn’t help but cry out louder and louder, “Ohhh, Ohhhhhh, OHHHHHHHHHHH!”
“You like that, don’t you, you fucking brat!”
“Yes! Oh, yes! Ohhhhh!”
In response, Kostas rammed his cock harder and harder against Lysithea’s small body. Her loud moans fueled him, serving as a reminder that he was in control. He was not somebody to be fucked with.
“Oh, fuck!” Lysithea exclaimed, “Oh, Goddess!!!!!!”
He wouldn’t waste any time with this one. Kostas came inside Lysithea, fully laying claim to her body. His purple mark on Lysithea’s crotch was a testament to that. Satisfied, Kostas pulled out of Lysithea and threw himself on his back next to her, hoping for a good rest after another job well done.
Suddenly feeling a weight on his chest, Kostas’s eyes shot open. He saw that Lysithea had stripped completely naked and was now sitting on top of him. She look annoyed, as she was pouting her lips like a child.
“No!” Lysithea exclaimed, “We’re not done! Fuck me again, Master!”
Kostas was a bit stunned, as he was not expecting this particular development. Kostas’s silence, however, only made Lysithea more annoyed.
Lysithea hit Kostas’s chest, “FUCK ME, MASTER! We aren’t finished yet! Put your cock inside me! Give me more of your cum! It tastes so good! I need it!”
Kostas’s crest had warped Lysithea’s mind; she was now acting like a kid asking for her favorite toy. Kostas smiled; he didn’t mind. The genius prodigy acting like the brat she is? He liked the way she was asking for his cock. He thought she was cuter this way. No more pretending to be an adult.
Kostas chuckled to himself; he would show her who was her daddy.
