"Isolet?"

"..."

Frey swallowed dryly and called Isolet's name, but there was no response from her.

"Isolet...? Sister?"

With an uncertain expression, Frey called her again, but even then, she remained silent, prompting Frey to finally heave a sigh of relief.

"...We survived."

- Plop...♡

Frey’s cum poured out of Lulu’s vagina as he pulled out his cock.

"...Lulu."

"Wo-Woof."

Watching her blankly, Frey tugged Lulu's tail and muttered.

"You can’t use this."

"Whimper..."

With a whimper, Lulu brushed her hip against Frey's penis.

"Never mind, we couldn't have hidden it anyway, since Isolet came in so suddenly."

"Heuk..."

Pressing her stomach with his hand, Frey sighed quietly, then turned his gaze to Isolet and muttered.

"Well, now what..."

Originally, Frey had intended to spend the night with Isolet.

However, for some reason, she didn't reply, and instead, Frey spent the night with Lulu, who did reply.

"What a mess..."

Judging from what Isolet said when she entered his room, it was clear she was looking forward to the night Frey had promised her.

Unless she noticed his intention along the way here.

"How did you enter the roo... Ah."

Grasping his head in frustration, Frey looked at the key in her hand with a dejected expression.

"Where did you get my room key?"

Of course, there was no answer.

"Ugh..."

"Well... let’s take a breather for now..."

Just like that Frey ruffled Lulu’s hair and kissed her belly. Then he tried to get up.

"As expected, Sister, next time..."

He murmured as he felt the soreness in his lower body.

"...I will serve you."

"...!?"

Suddenly, Isolet, who had been as still as a statue, began to speak as she undressed. Her eyes lit up with anticipation.

"Where are you trying to escape... No, I will carry out your command."

"Huh? Uh..."

"Hurry up and give me the vaccination, my lord."

Watching Isolet speak mechanically, Frey looked at her dumbfounded, then muttered as he tapped the ring of oath.

"Oh, did an error occur? Why is this happening?"

Watching the confused Frey, Isolet inwardly muttered with a sly smile that no one noticed.

I don't know what's going on, but for now, I’ll play along. You cheeky little brat.

"S-Sister."

"Yes, Frey."

Blushing deeply, Frey rested his cock on Isolet's head.

"This... Do we really have to do this?"

"A penis oath is essential before establishing a relationship."

Although Frey clearly had the ‘Ring of Oath’ that could forcefully control Isolet to his heart's desire, for some reason, she was in a trance and uncontrollable now.

Initially, Frey had intended to send her back to her room, even resorting to using the ring, but due to Isolet's killing intent, he reluctantly decided to have sex with her in her hypnotic state.

"Whimper..."

By the way, Lulu lay face down beside the bed, moaning, with her collar tied.

Frey had also tried to send her back, but she decided to stay just in case Frey might be in danger.

"...I'll have to come up with something to say later."

- Chuu♡

"Ugh."

When he looked at Lulu, Isolet took the opportunity to kiss his glans, making him flinch in surprise.

"S-Sisterr..."

Frey had been prepared enough to establish a relationship with Isolet.

However, having admired her since childhood and treated her as a mentor, Frey felt a sense of immorality as if he were engaging in a forbidden relationship in this situation.

"Slurp..."

"Ugh..."

While he was having that thought, Isolet wrapped her tongue around his penis, making it erect once again. Frey trembled with the immorality of it all, recalling the scene where she guided his swordsmanship.

"Smooch, Smooch, Smooch...♡"

"Haa, haa..."

Unfazed by Frey, Isolet took his penis in hand and began to kiss every part of it.

Moving from his glans to his shaft, to the root, and even his testicles.

"Nibble..."

"Ugh, uh..."

After marking his penis, Isolet sucked on his testicles, causing Frey to squirm.

"Slurp..."

Then she licked his cock from the base to the glans before putting it in her mouth

- Spurt...! Spurt...!

After repeating this several times, Frey's penis began to throb violently, spewing a copious amount of semen.

"Haa..."

Not missing a beat, Isolet placed Frey’s cock on her head once more. Then, she whispered calmly as his cum overflowed from her head and streamed down her body.

"With this, the cock baptism is complete."

"...What?"

"Now, I am both your knight and slave of this magnificent cock."

- Spurtttt...!

Even though he had already ejaculated enough to cover her head and body, Frey’s penis erupted again at her suggestive words. This time, Isolet swallowed his cumming cock with her mouth.

"Gulp, gulp..."

Thank goodness I took the aphrodisiac.

"...It's really delicious, Lord Frey."

Seeing Isolet swallowing the semen she had held in her mouth and then licking her lips, Frey muttered inwardly.

The effect of Irina's special aphrodisiac was evident from the amount of semen baptizing Isolet’s body.

"Now, please do as you wish, my lord."

"What?"

Thanks to Isolet's encouragement, Frey regained his confidence. Then she placed her hands on his knees, and spoke.

"As the eldest daughter of Marquis Bywalker, the swordswoman known as the strongest knight of the empire, and a professor at the academy, I hope you will thoroughly ravage me."

"..."

"I have sworn my allegiance to you and your cock, I will obey all of your command."

Then, she added that to show her loyalty. She closed her eyes and started to kiss his glans with sincerity.

-Smooch, Smooch...♡

Seeing her in this state, Frey felt a rush of conflicting emotions—immorality and admiration for her, as well as a surge of masculine pride—all at once which he had harbored for her for some time. Then, with a trembling voice, he issued a command.

"Isolet, it's an order. Act like you usually do from now on, like an older sister."

"Undershood."

Then, with her hands on his knees and a careful kiss to his glans, she replies in a hushed voice.

"Have you ever masturbated while thinking of me?"

Frey blushed as he extended the ring of oath to her, asking the question.

"...Yes."

In response to Frey's teasing question, she turned her gaze aside shyly.

"How often?"

"Every, every night... Almost every night, I masturbated more than three times without fail, thinking of you."

"Is that so...?"

Contrasting her previous mechanical demeanor, Isolet's embarrassed expression as she confessed to using him as a fantasy aroused a strange sense of confidence in him. He lifted his head to her with newfound confidence.

"Do you like me that much?"

"I like you, Frey."

"Say it as I command, not in that stiff tone."

"I like you, Frey."

As Isolet whispered sincerely, Frey's body heated up.

“Go to bed and do exactly what you did last night.”

"...Okay."

When Frey gave the order with a mischievous smile, Isolet lowered her head, her cheeks flushed with desire, and her body hot with anticipation as she made her way to the bed.

- Rustle, rustle...

"...?"

But then, Frey tilted his head as Isolet suddenly rummaged through her clothes on the floor

- Swoosh...

"Ha..."

Frey was taken aback when he saw what she brought out.

"You've been using that until now?"

"Yeah..."

What Isolet took out was none other than Frey's underwear that she had stolen from Frey's mansion a few months ago.

"So far, I’ve been using this underwear along with pictures of you for my nightly masturbation."

"...?"

"I don't have the pictures now... Should I go get them?"

Isolet seemed to be on the verge of tears as she asked those questions while holding Frey’s underwear. Seeing that scene, something snapped inside him.

"I'm right here now... Wouldn't seeing me directly suffice?"

"Ah... Well, I guess..."

"So, hurry up and masturbate as you usually do, you lascivious whore."

"...!"

With that, Frey started mocking Isolet, imitating Aishi's arrogant demeanor from the past.

"Can’t you hurry up? Could it be, is your pussy so old and dusty that you can’t even masturbate properly?

As Frey spoke, poking Isolet's abdomen, her eyes shook wildly.

...I thought she'd be happy if I did this?

However, thinking she might be upset, Frey decided to stop his unconvincing act if it didn’t work.

Clearly, the last time I did this, her response was explosive, so why isn't she reacting now? Is she in a bad mood?

- Swoosh, swoosh...

"Ugh, uh..."

As Isolet slowly began to caress her own fold, Frey swallowed dry saliva, lowering his gaze.

- Squelch, squelch...

Isolet's white hands move in and out of her pink, hairless, squishy pussy.

"Uh, haa... Haa..."

As her fingers became moist with her love juice, Isolet let out a sigh and pulled up Frey's underwear, moaning softly.

- Rub, rub...

"The reason I masturbate every night!! The reason I spent so much money on scrolls!! It's because you relentlessly wag your tail without giving me a moment's rest!! You brat!!"

Mercilessly, Isolet slammed her pussy down Frey’s throbbing cock and unleashed the pent-up frustration she had been accumulating.

"You were like that even when you were young! You! Always sticking to me, even when I’m drenched in sweat! Smirking at me! Intentionally getting close to me!!"

"Uh..."

"And then you say things like, 'I want to beat Sister too, you know?' You lecherous brat!!"

Isolet's pussy clenched around Frey's penis without mercy as she spoke.

"You tempt me like that, so why did you fuck me so late? You stupid jerk!!"

"T-That...♡"

"Don't make such a lewd face!! You always showed that expression to others, only to be mercilessly taken advantage of in the end!!"

"Uh..."

Thanks to this, Frey's cock reached its limit.

- Spurt, Spurttt...

Frey began to cum wildly inside Isolet’s pussy.

"Ugh..."

At the same time, Frey, who had still been held by Isolet's arms and legs, arched his back.

- Spurtt...!

"Uh..."

However, Isolet once again slammed her pussy onto Frey's penis, pinning him to the bed.

"S-Sister! Wait a min...!"

"From now on, I will teach you, Frey."

Isolet forcefully squeezed Frey's cock with all of her strength, which was about to go limp after just ejaculating, and began slamming it again.

"P-Please stop for a moment! Not now! Give me some...!"

"First of all, I'm not old. I'm still in my twenties."

And with that, Isolet’s lesson began.

"Second, my pussy is not old and dusty! I always masturbate every night while thinking of you, so it's very clean and warm."

- Spurt, Spurtt...

"Haah... Haah... Sister, please stop... Uh!"

Even though Frey begged with a pale face as he began to cum once more, Isolet's assault continued.

"Third, my pussy is not sloppy nor a third-rate! I can tell just by looking at your blissed out expression right now."

- Spurttt, Spurttt...!

After countless rounds, Isolet's grip finally began to loosen.

- Splurtt...

Frey had his head turned to the side, his body shaking as he once again filled Isolet’s womb and pussy.

"Haah... Haah..."

Looking down at him, Isolet blushed and whispered.

“Do you understand now? Frey?”

Sweat poured down her face.

"You can't beat me..."

Even in that satisfied state, Isolet, who had been murmuring contently, soon lowered her gaze with a dark expression and muttered under her breath.

"...In the end, you'll probably end up disliking this foolish me."

"..."

"Yeah. I don't know why you asked me to do this... But compared to someone much older like me, your peers would be better for you. So, let's end this relationship today..."

"Sister."

"Frey?"

Noticing Frey looking up at her, Isolet tilted her head.

"Even so, I still like you, Sister."

"...Ah."

Isolet closed her mouth upon hearing Frey's words and seeing his smiling eyes.

"So... Do you want to end this?"

"...Huh."

Upon hearing the following provocation from Frey, Isolet snickered while looking down at him.

- Chuckle...

Suddenly, Frey's flaccid penis began to throb violently, filling her vagina.

"I can still go all night."

Frey, who had already experienced all-night sex, still managed a gentle smile despite his tired complexion.

"...Cheeky brat."

Looking down at him, Isolet smirked to herself.

In fact, I've already gone several rounds.

But inwardly, she muttered with a trembling voice.

At this rate... I might lose to this brat.

Was it because of the cock baptism? Her uterus subconsciously recognized Frey's cock as her master.

Thanks to that, even now, with his glans poking at her cervix, Isolet's uterus was trembling with anticipation.

"Sister, so what should we do..."

- Thwack!

"...Heukk."

But unwilling to lose the upper hand, she gritted her teeth and thrust her vagina onto him again.

- Thwack, thwack...

"I, I love you, Frey."

"I love you too, Sister."

And so, a long night began to unfold.

.

.

.

.

.

- Thwack, thwack, thwack...!

"Heuk, ah, ah..."

Moans of pleasure echoed throughout the room.

“If you keep moaning doing this, the other professors will hear your moan, Sister.”

"You, ah, noisy..."

However, the recipient of those moans was slightly different this time.

"Ahh..."

Isolet, who was being penetrated by Frey in a doggy style position, soon blushed and muttered.

"But, really, you didn't use any contraception spells?"

"I didn't."

"...Why are you so vigorous then?"

To Isolet's incomprehensible question, Frey whispered with a hoarse voice, burying his head in her neck.

"I'm going to impregnate you today, Sister."

"...!"

Isolet's pupils dilated upon hearing those words.

- Spurt, spurt...

"Oh, there it goes."

Simultaneously, while still impaled on Frey's cock, Isolet squirted copious amounts of love juice.

"Ugh, ugh..."

"You finally came. I was getting worried you couldn't."

You... have ejaculated more than I do... you idiot.

Seeing Frey muttering to himself while wiping the sweat off his forehead, Isolet, who had tightly gripped his cock with her vagina, looked at him incredulously and muttered to herself.

"Is it because I feel so proud to be able to devour the sister I've always respected and looked up to from the back?"

"Y-You talk too much..."

As she blushed and murmured those words to Frey with a sheepish grin, she suddenly stopped mid-sentence.

"...Grrrr."

"Ah."

At that moment, Lulu, who had been tied up all this time, managed to cut her leash with her teeth and growled as she approached them.

"You said you would make me pregnant too, Master."

"Huh, that's... You’ve already had enough..."

"Not yet. I haven't reached my half of my limit yet."

"T-That, that can't be..."

Frey muttered with cold sweat, looking at her.

"...Pets shouldn't interfere."

Isolet chuckled and muttered.

"Get the kid out of the room."

Upon hearing Isolet’s sarcastic remark, Lulu's eyes gleamed ruby-red as she responded.

"Master fuck me first."

"..."

Thus, the two girls began to stare coldly at each other.

...This is an opportunity.

Watching them, Frey had actually been at his limit since earlier.

- Plop...♡

As he quietly removed his penis from Isolet's pussy, he started to sneak out of bed.

"Where are you going, Frey?"

Isolet, immediately turning her head upon feeling the cum dripping from her pussy, looked at him coldly.

"Master... Please don't go... I'm lonely..."

With Frey frozen in place, Lulu pounced on Frey, and knocked him down on the bed.

"Little brat, step aside for a... Huh... are you a demon?"

"Master... is mine..."

"Ah, ah..."

Watching them both reaching out to him simultaneously, Frey closed his eyes tightly, feeling a familiar sensation he had experienced that day with the main heroines.

.

.

.

.

.

"Ugh, ugh..."

Meanwhile, at that time...

[And what happened next was obvious.]

With a hollow gaze, Roswyn was busy jotting something down in her notebook.

[Isolet and Lulu were entangled, pressing their navels and lower lips together, while Frey inserted himself into between the two...]

- Squelch, Squelch!

- Ah, ugh...! This cheeky brat...

- M-Master, please, me first...

With a vacant stare, Roswyn continued jotting down her observations as she watched the scene unfolding in front of her.

- Squelch, Squelch...

Pausing for a moment, Roswyn whimpered as Frey thrust into the women, aligning her movements with his rhythm.

"Why am I even writing this down..."

Eventually, as the two women climaxed, she also arched her back.

"Even this... could be considered indirect intercourse with the Hero."

Roswyn murmured with a distant expression as she felt her love juice gushing like a fountain from her own pussy.

“I want to get fucked too...”

Then, she puts the notebook aside and looks at the video.

"I, too, can provide a satisfying squeeze... I, too, can enjoy the taste of semen... I, too, have my virginity intact... I've kept it all this time..."

Watching Frey's member thrusting into Isolet and Lulu's vaginas alternately, she continued murmuring with dead eyes.

"I, too, want to be impregnated by the Hero..."

Unbeknownst to her, the day was /genesisforsaken
