==========
The reply to the letter came, and after various arrangements, today is the day of the party, but...
"Huh? The maid and mother suddenly couldn't make it?"
"Yes... It seems Mother and Sister-in-law had to go with Brother because he suddenly had something come up... So only Leviathan-sama will be visiting today..."
Why the sudden engagement...? I had confirmed all the schedules beforehand. And going with a Demon Lord's business also sounds strange. ...Perhaps, my plan has somehow leaked to Demon Lord Sirzechs or the Gremory family. But if that's the case, I don't know if Leviathan coming here is a trap or genuine... She is a Demon Lord, after all, and her power is tremendous, making it even harder to tell.
Well, perhaps... this might have been for the best. Even with my female slave women, it would be difficult to corrupt three renowned powerful devils all at once. So, for now, I'll make Leviathan, who fell into the net this time, mine first.
"Well, that's fine... Everyone will eventually come over to my side anyway. More importantly, hurry up and milk me with those proud 99cm enormous breasts."
"Understood, Master."
I had Rias give me a paizuri to get off my first load of the morning.
Normally, I'd cum about 5 times, and to be honest, paizuri isn't enough, so I'd definitely violate her.
But this time, I need to hold back to some extent to violate Leviathan. That's why I'm only doing paizuri.
"Mmm... Nn..."
While Rias is working hard, I'll summarize the key points for this time.
First, after calling Leviathan to the Hyoudou family's basement, prevent her from escaping by some means. Giving her commands or high-proof alcohol should do the trick.
Next, keep jumping to random places with the magic circle, and after arriving at my house, only activate the magic circle. Kuroka and Le Fay are in charge of that magic circle. I had them secretly go and set up teleportation magic circles all over the world.
Once we arrive in my room... or more precisely, that specific room, the training begins, it's my turn.
Yeah, so that's pretty much it. I've summarized it very simply, but it's roughly like this.
"Alright, I'm coming...!"
"Aahh!"
Now then... how shall I violate Leviathan when she comes...? Hehe, I'm looking forward to it.
…..
"Sona-chan! Thank you for inviting me to the party~!!"
"O-Onee-sama... Please calm down, there are other people watching."
The Hyoudou family's mansion, like a castle, sits in a reside ntial area.
In its basement were Rias Gremory and her female peerage, Sona Sitri and her female peerage, and Serafall Leviathan, Sona Sitri's biological elder sister and also a Demon Lord.
Serafall was participating in a party conceived by her younger sister Sona and her close friend Rias.
She was hugging Sona out of happiness, but Sona, due to the extreme closeness, seemed embarrassed and tried to pull away.
"...Huh? Rias-chan, by the way, what about Grayfia-chan and Auntie? I heard they were coming..."
However, as she couldn't see her acquaintances who were still not present, her demeanor quickly returned to seriousness. And the one who answered Serafall's question was, of course, Rias.
"Sister-in-law and Mother went with Brother on his work. He said this morning that some work came up that required the two of them..."
"So today it's just me and Sona-chan's group for the party? That's still plenty fun, but does that mean I won't get to see those two until next time?"
Serafall somewhat casually asked Rias, hoping to talk to those two again after a long time. However, Rias shook her head and replied:
"Unfortunately, this time it will be held without those two... but if the opportunity arises again, I intend to invite them."
"Rias-chan... Mmm, well, then let's enjoy ourselves for their share today ♪"
"Yes!"
Everyone raised their wine glasses and toasted, but since most of them were minors, Serafall was the only one drinking wine.
"This wine is delicious☆... Where did you get this?"
"I received it as compensation for a devil's work some time ago. I was planning to give it to Mother and the others, but there are still enough bottles, so I thought I'd open one here."
The wine in Rias's hand looked quite expensive.
Compensation is something that arises from a judgment that the value is equal only when objectively judged, but conversely, Leviathan suddenly wondered what kind of work was done to receive such an expensive-looking alcohol. Sensing her question, Rias explained with a slightly wry smile.
"I haven't done any strange jobs. Even as compensation, sometimes the client pays more than the value of the request... Besides, Akeno and I are often mistaken for being older than high school students, so we sometimes receive things with age restrictions like this.
In such cases, we usually entrust them to the Gremory family or give them to Mother and the others to consume."
"Ah, I see☆
But in the human world... or rather, in Japan, there probably aren't many people who have this kind of alcohol, right? You can buy it, but it should be quite expensive... Wait... Huh...? I suddenly feel... sleepy—"
After draining the wine in her full glass, Serafall began to complain of sudden drowsiness.
However, it wasn't because she was sensitive to wine, she was simply genuinely sleepy. The wine she drank was indeed wine, but it had been laced with a drug.
"...Has she fallen asleep?"
"Yes... Perfectly."
The man who opened the door and entered was Kaneo Tsukishiro, the one who had reduced them to his female slaves.
He had ordered Rias to secretly drug the wine glass beforehand. Instead of powder, he had applied a thick, ointment-like substance, thinned it out so it was invisible, and coated the inside of the glass. Serafall, though not particularly weak to alcohol, drank the wine mixed with the dissolved sleeping drug. Devils, by nature, have no different resistance to drugs than humans.
Even if there are diseases that devils contract, the medicines to cure them naturally become devil-specific. Therefore, if you use a sleeping drug, you use one for devils. That's all there is to it.
"Then,President... I'm going to teleport now, so hold onto me for a while."
"Yes... Please do."
As he said that, Sona hugged him without hesitation. He, completely unfazed, picked up Serafall, who was dressed as a magical girl, over his shoulder and somehow squeezed her butt through her underwear when it came next to his face.
"Mmm..."
"...Alright, let's go."
Perhaps because she made a sound, he looked satisfied and, along with Sona, stood on the magic circle and disappeared from the Hyoudou family's basement.
POV Kaneo
"Ugh... I'm drunk..."
I thought I was getting used to teleporting with magic circles, but flying all over the world really makes me dizzy... Plus, since it was all over the world, there was rain and snow, and the sudden changes in weather, temperature, and humidity might also be to blame...
"But... we've arrived at your house, so shouldn't we hurry?"
The Chairman is urging me. A younger sister trying to pleasure-corrupt her older sister might be a rare sight. Well, I'm planning to have the Chairman help out this time, so I'll just watch for a while.
"But yeah, it's certainly better to be quick."
So, I entered that room and tied up Serafall. I hung her from a suitable spot and bound her limbs so she couldn't move. Then, as usual, I set up 4K video cameras. This is the memorable first AV of the Magical Devil Girl... I even prepared multiple video cameras carefully.
After tying her up, I rearranged the room and hid in a suitable spot to observe the interaction between the Chairman and the Magical Devil Girl.
"...Onee-sama, please wake up, Onee-sama."
"...Mmm, huh? Sona-chan? When did I fall asleep... Huh? Sona-chan? Why am I tied up?"
Serafall asked the Chairman nervously, her lips twitching... Why is she so scared of her sister just because she's tied up? Does she have any idea that she did something to get tied up...?
What exactly does "tied up" even mean?
"That chest... Despite wearing clothes that easily show your body line, were you boasting about having bigger breasts than me, Onee-sama?"
"So-Sona-chan? Your face is scary and I don't quite understand what you're saying... N-hya!?"
"To have such big, easily fondled breasts made even more visible by a tight outfit that makes your nipples poke out, and then to wear a mini-skirt and constantly flash your panties... Onee-sama, are you a slut or an exhibitionist?"
She kneaded Serafall's breasts over her magical girl costume. I had left it somewhat to the Chairman, but maybe she was a little irritated about her style... because she was grabbing her nipples through her clothes and pulling them...
"W-Wait, Sona-chan... That hurts, okay? Did I do something to upset you, Onee-chan?"
"...If I had to say, if I had to say, it's that I wanted to vent all the pent-up frustration until now... is what I would say?"
Saying that, the Chairman tore off Serafall's magical girl costume... She had been holding back until now, but perhaps now that I've created this situation, she can't stop herself...
After tearing off the panties that were hiding her important parts, she fondled Serafall's breasts with both hands and began to lick her secret slit, which was surrounded by glossy black pubic hair, as if to slurp it up.
"Slurp, slurp!"
"Nnn! No, Sona-chan, stop! I'm sorry! Girls shouldn't... especially sisters shouldn't do this! Nyaa!"
However, the Chairman completely ignored Serafall's pleas, in fact, her desperate cries seemed to make her even more heated... I thought the Chairman had some M tendencies, but it seems she also has S tendencies... I'm scared she'll try to reverse-rape me eventually.
"Phew... You say stop, stop, but Onee-sama's here is so wet with pleasure, isn't it?"
She shamelessly fiddled with Serafall's secret slit and showed her the sticky liquid dripping between her fingers. Serafall looked away, unable to look directly, but she couldn't hide her flushed face. Serafall seems like an M.
"Onee-sama? Even if you avert your face, I think you should admit the fact that you're feeling good even while saying you don't like it, Onee-sama?"
Wow, she has such a satisfied look on her face... And she's bringing it super close to Serafall's face so she can see it even if she looks away, and bringing it to her nose to make her smell it...
"Onee-sama, please lick and clean what you've dirtied with your own."
"Nn-buh!?"
Ugh... She's not exactly forcing her, but she's putting her finger in her mouth and making her lick it... But the fact that she's licking it without much resistance, is she giving up, or is it because it's her sister that she doesn't dislike it...? Well, either way, it's the same to me, so it's fine.
"Churu... Rero..."
"Fufu... That's good, Onee-sama, you're cute even when you listen to me like that..."
The Chairman is definitely a sadomasochist.
Making her sister lick her fingers and having an ecstatic expression reveals a twisted sisterly love.
"Here... I'll loosen this up for you too."
"Nn-buh!? So-Sona-chan?! That's not right! That's dirty, nghh!?"
...Even though she had saliva on her hand, she put her index finger of the other hand into her anus. I like anals too, but scat isn't the goal, so don't overdo it, Chairman.
"Not right? But you're clenching so tightly as if you don't want me to leave, aren't you? You really like being done in this hole too, don't you?"
"N-No! Don't move it!"
Oh, damn, she started gathering magic power in her palm. I've been able to seal movements with this until now, but it's dangerous if she forcibly accumulates magic power... No choice, I'll use Tentacle King. I've already clapped my hands, as it's set to summon only the aphrodisiac-injecting tentacles when I do, but—
"Nn-hee!?"
"W-Why me too...!!"
The moment I called it, it pounced on those two and injected them with aphrodisiacs. Isn't that too fast? I summoned it from my side , but it flew over there in an instant. But thanks to it injecting them, Serafall's accumulated magic power dissipated, and her body is probably so excited that she can only think of erotic things now.
It seems it's fine to go out now.
"Ngh!? W-Who are you...!?"
"Oh... You still have the energy to talk. Even though she's a pretty strong one, she's still a Demon Lord after all."
Next to me, the Chairman is writhing uncontrollably from the intensity of the stimulation, even though she's doing nothing. How can she endure it...? But if I give her strong pleasure, she'll probably fall easily, so should I untie them and go for a sister sandwich?
"A-Answer me... Is it you who did this to Sona-chan...!"
"If I had to say just one thing... you're going to be my female slave for the rest of your life. If you're lucky, you might even become the female slave of others. Oh, is that if you're unlucky? Well, either way is fine."
"Answer me!!"
"Whoa...!"
A hole in my stomach... or rather, in this case, since it's quite wide, should I say a hole opened in my torso? I thought that after being injected with a pretty strong aphrodisiac, and her magic power dissipating once, she wouldn't be able to generate it anymore, but I didn't expect her to still be able to. Even a slightly stronger dose might not break her yet, but if I hit her any more, she might lose consciousness during foreplay, and I'd be annoyed if she broke that way, so it might be just right to leave her with this much defiance.
"Ngh...!? W-Why are you so calm even with a body like that...!? It's strange...!"
"You didn't think I was crazy for doing something like this in the first place, did you? You say you're a female Demon Lord, so I thought you'd be devouring men, but you're surprisingly innocent."
Does that mean she's still a virgin? I can understand it for Rias or the (formerly) serious Chairman and her peerage, but she's quite a bit older, so I thought she wouldn't be a virgin. But if she is, then this reaction makes sense. Well, seeing the Chairman's transformation, once this one knows a man, she'll probably start hunting for men and devouring c*cks. The Magical Devil Girl is upgrading to a Magical Prostitute, huh?
"What...!?...Who are you? If you're not from the Khaos Brigade, then who are you?"
Oh, you mean the terrorist group rumored around town, right? Now that you mention it, I guess there was something like that, but sorry, I completely forgot.
"Ah... Er... I'm not a terrorist. But right now, I'm your enemy. Though you'll come to worship me later."
"At the very least... I can't imagine I'll be able to worship you later when you're doing this to me now."
She's blushing from that aphrodisiac and feeling it a little, but it's amazing how she's suppressing it and not saying a word. But that patience is a thin, thin wall like yuba, and—
"Then I'll make you worship me."
"Ngh!? Ugh, J-J-Just...!!"
Just lightly stepping on her secret slit with my foot and moving it allows me to easily break through. Patience is poison to the body, so she shouldn't have endured it. And then I move my foot without hesitation. The sole of my foot immediately gets soaked with love fluid, but I've taken off my socks, so it's not a big problem.
"I-It hurts!! N-No, stop it!!"
She's crying and begging. A plea born not of will but of instinctive fear, begging not to receive any more pleasure. The woman who just moments ago said she wouldn't yield is now like this. But I've heard that people can endure pain-induced stimulation, but they can't endure torture by pleasure. I don't know the reason, it's just a rumor.
For now, I'll take my foot off and let her rest.
"Haa... Haa...!"
She's breathing somewhat hyperventilating, but... yeah, the drug is working pretty well. She's enjoyed a pleasure far beyond what the Chairman did to her earlier, but this is still nothing. I'll make her cry and moan even more. Until she worships whoever's c*ck it is!
"If that doesn't work, then this is next."
"No, stop... My sin is still light now..."
I was about to attach the vibrator I took out, but her last words made me stop.
Did she really mean what she just said? If she didn't mean it, did she say it to reassure herself? No, no, if she was going to say something like that, it would have been better to say nothing at all. So why did she say it? There's only one remaining answer. She said it because she really believed those words.
How ridiculous... I wouldn't change what I'm doing just because the "sin is light" and it might not leave much of a mark later. If I could be stopped, I wouldn't have started in the first place. However, I'll crush this woman's hope here... completely.
"Hey... Why do you think I'm here? Why do you think I can do this? Why do you think you fell asleep? Why do you think I was able to incapacitate you? And... why do you think you ended up like this?"
"Eh...?"
I kept pressing the questions without giving her time to answer, but there's only one answer. However, even if she understands it, she won't accept it, and even if she does accept it, her rebellious spirit won't disappear, so I'll just corner her relentlessly.
"I'm here because I brought you to my house. I was able to do this because I have collaborators. You fell asleep because someone drugged your glass. You were incapacitated because someone knows your habits.
So... to know your habits, you need a long-standing relationship. Who has the longest relationship with you among those? And among them, who can build a relationship with me? Who could have tampered with your glass, someone you trust the most and who would easily be excluded from suspicion?"
"Ah... Ah...!"
She's pale. She seems to have understood, even though she doesn't want to believe it.
I pressed on even further from there.
"I don't go to the Underworld. As you can tell, I'm a student.
So, among the people at Kuoh Academy who know you and have the longest relationship with you... You already know, don't you? That's right! It's your sister, Sona Sitri, who's right here!"
"W-Why... Sona-chan..."
"But rest assured, your sister's wish wasn't your downfall, but to live as a female slave who can serve anyone's c*ck for the rest of her life, together with her sister. Lucky you, your sister's a good girl."
I looked at Serafall's dazed, soaking wet secret slit and became convinced: I can put it in now.
Just thinking about what kind of expression this woman will make while moaning sends shivers down my spine.
