Euclid's Side Story
Well then, it's my turn to speak. First, I did something to bring down my elder sister. That was to capture her.
"Oh, you might think, 'That's obvious,' but it's not. My sister was originally the wife of the Demon Lord Lucifer... Sirzechs. That's why I had to confine her in a place where it absolutely wouldn't be discovered. However, to do that, I was a bit short-handed... So, to execute the capture, I decided to target Rossweisse, a Valkyrie.
"Well, I already had a slight acquaintance with her, so I easily abducted her. How did I manage to subdue her, a woman with powerful magical abilities? Let's start there.
"First, I developed her chest. In short, to make her extremely sensitive and lustful... Her sensitivity was originally good, as she learned to reach climax from just nipple stimulation within a few hours, despite it being her first time. I trained her to climax quickly in various places and through various methods: kissing, breasts, secret clefts, clitoris, anus...
"However, her core was as hard and strong as my sister's.
"'Hah, hah... This won't... break my spirit... Euclid Lucifugus...!'
"'Breaking you? Not at all. I just want you to be on my side. I told you, didn't I? 'I need your help to make Grayfia Lucifugus mine.'"
"'I'd never do such a thing... Even if I succumb to pleasure, my spirit won't break...!'
"Yes, she said she didn't want to help with evil deeds. But I wanted to get my sister back into my hands as quickly as possible.
"That's why I was going to humiliate her for not helping... but even I was at a loss as to what to do.
"After all, I had to consider the premise of getting Rossweisse, just for the premise of getting my sister.
"However, as I researched her, I suddenly realized something. Yes, it was simple.
"'...You suddenly released me, and now a feast? There doesn't seem to be any medicine in it... What are you up to?'
"'No, I have no ulterior motives. I just... want to apologize for the rudeness of what I've done so far.'
"I apologized. Pride? For me, getting my sister was far more important.
"So, why did I do this? Firstly, because what she desired was a 'boyfriend.' At first, it seemed almost vulgar. However, she had lived a life of constant vigilance. And a boyfriend was the 'place of peace' she desired. So, I decided to become that safe place for her. Adorable and dignified, yet sometimes displaying femininity... Indeed, the more I looked, the more she resembled my sister, I thought.
"'...I'll eat.'
"Although she was still confined, she gradually began to relax. It was as if she was at home. But that's what I wanted. That was the tendency I desired.
"It might have taken several months... maybe even a year for that.
"'...Rossweisse-san, are you having any difficulties? Please tell me if anything is inconvenient. I'll consider anything except release from the mansion.'
"'...It's not exactly 'release,' but I want to go outside. I feel like my head will go crazy if I don't go outside for so long. Even exercising with equipment doesn't change that. Is it okay if I go out for about an hour?'
"'I can try to arrange that much for you.'
"And she started asking me for more things. However, around the same time Rossweisse-san could no longer endure it, I also found something I couldn't endure anymore. Yes, it was about my sister. So, to shorten this long wait, I secretly replaced the incense Rossweisse-san was burning with something that heightened sexual arousal. And I changed the bathwater and shower water she used during bathing into aphrodisiacs.
"Perhaps because she was bathing in and smelling these every day, Rossweisse-san's face grew redder day by day, and her desire to do something lewd became impossible to hide.
"'What's wrong?'
"'N-Nothing...'
"However, its effect was too weak to make her lose her reason. After all, it was incense burned only in her room, so perhaps its effect gradually waned over time.
"But just because I was impatient didn't mean I could make mistakes. So, I decided to stay as close to her as possible. Of course, following her into her room would make her wary, so I just suppressed my presence and touched her shoulder... that kind of thing.
"But thanks to the incense, her vigilance was gradually diminishing more than usual.
"'Ah...'
"'What's wrong? Why that face?'
"Since she was already trained, Rossweisse-san called me into her room relatively quickly.
"Even if she had a lover, she must have come to the conclusion that she was already defiled.
"So, surprisingly, once I pushed her down, she fell pretty quickly. Though the drug's effects also played a role.
"'This time, just this time...! So, I won't submit to you... Hmph!!'
"'Yes, I understand. So, no matter how much you crave it, everyone knows that 'you haven't submitted.'
"By daring to deny it, I make her misunderstand. Even though she's truly fallen... So, I defiled her again and again. Missionary, cowgirl, reverse cowgirl... I used various ways to defile her.
"'How is it?'
"'Hahi... So good...!'
"'Oh, have you submitted? You said you wouldn't submit so much.'
"'It's so good...'
"To her, who was climaxing so much that her words became slurred, I dealt a further blow.
"If her mind was blank, I'd make it even whiter.
"Let's see, about three days after I pushed her down? By then, she was already addicted.
"'More, give me more...'
"'Fufu, I'll give it to you if you listen to what I say.'
"Thus, I obtained one of the hands I needed to get my sister.
"Control through pleasure may be a safer form of control than force... although it has the potential to make capable individuals no longer capable.
Grayfia's Side Story
And next, it's my sister. First, I had Rossweisse-san enter the Gremory household.
At that time, I used magical assistance to interfere with perception.
And one of the empty rooms was connected to my place by her magic. With that, the preparations were complete.
I was convinced that her power as a Valkyrie was truly remarkable.
Once the room was ready, all that was left was to isolate her. With Rossweisse-san's help, I managed to secure my sister. Well, all I did was put her to sleep with magic.
Also, I created an exact replica of the room. This made the feeling of isolation even stronger.
"'Ah, you two... What are you going to do to me...!'
"'It's decided, isn't it? I'm going to make you mine. Right? Rossweisse-san?'
"'Y-Yes...'
"'...Making me yours? You're a million years too early for that...!'
"Yes, she was very strong-willed. However, I believed my sister should be that way, so I wanted to see that strong-willed, noble, and calm demeanor crumble.
"And with Rossweisse-san's help, I first increased my sister's sensitivity. However, increasing her whole body's sensitivity would be meaningless, so I had Rossweisse-san use something that concentrated all sensations on one point.
"'Hngh!? No...! My senses are too sharp!!'
"Concentrating on one point turned out to be surprisingly interesting when used. If I pulled her nipple, her face would turn bright red, and she'd make a scream-like sound while climaxing. Perhaps she instinctively felt it was dangerous for climax to come all at once?
"However, I thought I had to do at least that much for training. And as her sensations gradually returned to her whole body, I just kept stimulating her nipples.
"'Mmm, mmm, mmm!!'
"'...Phew, my tongue gets tired if I keep doing this. Rossweisse-san, I'll leave the rest to you.'
"'Yes...'
"However, I get tired alone after all. So, I left it to Rossweisse-san for a while.
This is also a benefit of having two people, in a sense. And after continuous kissing (of course, I let her rest so my tongue wouldn't cramp if I really did it continuously), my sister was able to climax from just kissing.
"'Kissing, nipples, breasts... Next, perhaps her butt? Well, she's not a virgin and already has children, so it shouldn't be that embarrassing.'
"'H-ugh...! Nggh...!'
"With anal beads, my sister developed another erogenous zone. Leaving the vagina for last was my preference... a perversion, I suppose.
"However, my sister's face was bright red, perhaps because having the most important part for sexual intercourse left for last was quite embarrassing.
"'Fufu, I've just discovered that even that expression looks wonderful to me.'
"'...You pervert...!'
"'Your defeatist words are merely an aphrodisiac now. Your frustration will be my nourishment... So, I'm looking forward to when you become mine. Well then, shall we be together again today?'
"'Kuh...!'
Grayfia's Side Story (Continued)
"'Hya! Ha, nn, nnn!!'
"It's been about a week since I seriously set out to bring her down, perhaps? My sister, who no longer even tries to hold back her voice, still hasn't completely fallen. However, the fact that she can no longer hold back her voice also means she's exhausted, so perhaps it's time to use the final blow?
"That's what I thought. This time, Rossweisse-san is also here, so I'll be able to get more definitive testimony.
"'Sister, are you going to resist again?'
"'...You're just... so bad... that I can't... fall.'
"My sister, panting, wore a 'gotcha' expression. It's in my nature to want to bully her more when she reacts like that.
"It's obvious to anyone nearby that she's putting on a brave front. That's why she's so much fun to torment, though.
"'Is that so? Yet you're making sounds.'
"'...Someday, I'll get out of here...!'
"'Someday...? And when is that 'someday'? Also, you just said you'd get out... How? Will you call for help from your incompetent husband who still hasn't tried to help you?'
"'I wouldn't make Sirzechs deal with such trivial matters... He believes I can escape on my own...'
"'...If you truly believe that, it's quite comical. Well then, let's leave you alone for a while longer.'
Grayfia's Side Story (Continued)
"'Are you really going to escape? The door isn't locked, your body isn't bound, and I haven't done anything with magic or given you any drugs. I simply placed a vibrator there.'
"'U-Ugh... My body is hot, I can't stop it...!'
"And I left my sister in the room and waited for a full day. I literally made it so she could escape at any time... but my sister didn't escape. She didn't choose to escape.
"'That's your answer... You had a chance to escape from my grasp, but you lost to your lust and forfeited it... Of course, I didn't manipulate you with magic or give you any drugs. Yes, you simply lost. You had already fallen... to your own sexual desires.'
"'I, I... already fallen... Ah, aha... then... I don't have to hold back... anymore...?'
"'Yes. You'll become mine instead... Is that okay?'
"'It's okay... More, give me more of yours! No... Please, give me yours, Master Euclid!!'
"And that's how she fell. In the end, she was also just a female. I couldn't resist when I saw her fall.
"After all, I had obtained what I wanted.
Kaneo's Side Story
"You put in a surprising amount of effort, don't you?"
"For my sister's sake. Thanks to that, her previous dignity is gone, and a perverted side has emerged... But that's also good."
Euclid said with a sharp face. This guy is also a pervert in his own way... Well, he's an extreme siscon, so I guess it's not surprising.
Anyway... The last one is Kuroka's former master. I don't know what kind of guy he is, so I'm a little curious.
