Chapter 251 Interlude: Mashiro’s Experiment (Tentacle Edition)*
Edited by: Kanaa-senpai
A few days had passed since that business with the bestiality.
”So, you want to experience the tentacles too, then?”
”Of course.”
I let out a sigh. Even for someone driven by an insatiable curiosity to uncover the unknown, this is beyond the pale. She’s an absolute pervert, no doubt about it. By the way, when I asked why she wanted to know so much, she answered that the unknown is fear.
’I was always a bit of a coward; the unknown used to terrify me. Ghosts, the occult, UFOs, cryptids, and death… those were the things I feared. That’s why I researched everything, trying to turn the unknown into the known so I wouldn’t be afraid. I eventually realized that things like ghosts were mostly just hallucinations born from psychological fear-nothing to worry about. Before I knew it, I’d become a seeker who had to know everything. That fear came rushing back when My Master transformed into the Barghest¹, but in the end, that’s where it all starts. It’s all just so I won’t be afraid anymore.’
I understand what she’s trying to say, but even so, she didn’t have to go as far as interest in bestiality or tentacle rape. Well, since she herself desires it, there’s no reason to heartlessly refuse. I did refuse the Futanari-ization, as expected.
”Well, I don’t mind. I don’t exactly hate seeing Mashiro all disheveled and lost in debauchery myself.”
”Isn’t My Master quite the pervert himself?”
”I don’t think there’s a man alive who hates seeing a woman lose herself like that. Well, aside from a very small minority.”
The two of us chuckle together. We aren’t equals, and if anything, I am in the superior position, but I have a favorable impression of her being able to trade nonsense like this. Leaving aside romantic feelings.
”So, should I take off my clothes?”
”As long as they aren’t favorites or expensive items, you can keep them on. If anything, Tatei will repair them. Besides, tearing clothes and making you naked is fun too.”
”You really are a pervert.”
I’m well aware.
* * *
”Please, go ahead.”
I let out a deep sigh.
…This is the first time I’ve ever had the person I’m about to violate say something like that to me. I guess she’s just that expectant.
”What’s wrong? You aren’t going to say you’re stopping now that we’ve come this far, are you?”
”…I’m just amazed by you.”
”…I think it’s a bit late for you to realize I’m this kind of woman.”
That is true. Just to be clear, Honoka and Mihiro don’t say things like that. They certainly say lewd words before we do it, and I know they are expectant, but they don’t say things like “Now, please enjoy.” I’d like them to do the ‘The present is m-e’ thing with a Naked Ribbon, but they go beyond that with stuff like ‘Please discipline the trash p**sy of this lewd, super-slutty Heat, ero-ero female Servitude’…
Regardless, they say only a fool turns down a meal served on a silver platter.
”Fine. Don’t blame me for whatever happens next.”
”Oh, I wonder what will happen. I can’t wait.”
I’ll stop thinking deeply. In that case, I’ll just enjoy the way Mashiro breaks. My body collapsed, shifting into the form of a giant eyeball with accompanying tentacles. It was a Demon’s Eye²-a type of demon considered as difficult, if not more difficult, to subjugate as a dragon. Generally, demons and Mazoku are treated as the same rank, but in reality, they’re completely different beasts. In the first place, the existence of a demon is strange as a living creature. Not just the shape and form, but the thoughts, ability, and various other things are items that humanity cannot understand.
”You said tentacles, so I thought it would be a Roper or a Man-eater, but to think it’s a demon.”
’Well, yeah. But this guy is pretty strong. It’s weak to holy magic, but it still resists, and sometimes nullifies it. It’s hard for sorcery in general to work on it. Plus, I can send out thoughts like this.’
”Setting the body aside, it’s convenient. For that… isn’t it just My Master’s personality as it is?”
’Because this guy doesn’t have such a thing as an ego. Naturally, my personality comes to the surface. Well… because it has no ego, even though it has useful power, it was almost a wasted treasure. This Telepathy is the same.’
However, this Telepathy has the drawback that it cannot be used unless in this form. Other than that, things like Demon Eyes or Evil Eyes-those types of things-are lower-tier versions of the Unique Skills ‘Seven Deadly Sins’³, so they aren’t necessary. I mean, beams shooting out of the eyes? LOL warota.
’Well then… let’s get started!’
A swarm of tentacles crowded around Mashiro. I bound her limbs and hoisted her into the air. Even so, Mashiro just accepted it without any resistance. On the contrary, she was directing an expectant gaze. Whether she was excited or not, her breathing was rough and hot. A single tentacle slithered beneath her clothes. It crawled around inside before bursting through the fabric from within. Her modest breasts and pure white panties were exposed. As expected, she was expectant, or perhaps she was stimulated a bit by that just now; her small n**ipss were standing up.
Even so, these panties are almost the same as the ones from the world I was originally in… this is likely the result of Yokoo summoning a rubber tree with Materialization Summoning and Tatei refining rubber with Materialization Alchemy. They are precious items, but they are gradually circulating. However…
’I think this every time I see them, but it’s surprising that they’re white, even if they have lace woven in. I thought you’d be wearing purple or some other color of panties.’
”I prioritize practicality. Comfort comes first; color is secondary.”
’Then wear some open-crotch panties you can do it in immediately.’
”I’ll do my best.”
The lewd underwear will be for another time. For now, I’ll just torment her with tentacles. A tentacle gripped the front of Mashiro’s panties, wrenching them upward and forcing them to bite into her p**sy.
”Nkuuh! It’s… biting in! Ah, n-ah, aaahn!”
The fabric wedged inside began to dampen. I could tell exactly how much she was feeling it. I kept pulling, forcing it deeper, until the fabric finally gave way and the tentacle tore her panties to shreds.
”Kuhaaan! N, haa, fuu… at this level, it’s still no different from normal s*x.”
’Of course. It’s just the prelude.’
Three tentacles, different from the one that tore them off, attacked Mashiro. While a Demon’s Eye’s tentacles usually have rounded tips like earthworms, these three had suction-cup ends. They latched onto both of her n**ipss and her clitoris, beginning to suck.
”Nhii-in! My n**ipss and clit, both at once! Ah, hi, a-hiin! This feels incredible! Ah, ahin, ha-hiiiin!”
’Not yet. Since we’re at it, taste my Skill too.’
A slimy tentacle thrust into Mashiro’s mouth, violating her oral cavity.
”Obuh!? Gu-puh, juru, jupu, dyururururu! Kobu, nbu, nguuuuuu! ‘What is this? This mucus is sweet… so sweet my head is going fuzzy… wait, what?’”
’Ah, if we’re in contact, we can exchange each other’s thoughts. It’s convenient.’
’It really is convenient. And… it feels amazing.’
Unfortunately, it won’t end at this level. This mucus is an aphrodisiac created from the ‘Aphrodisiac Bodily Fluids’ I Snatched previously. It’s high purity and would normally be highly addictive, but I’ve already improved that part, and the addictiveness is almost zero. However, the effect has become even higher. On top of that, I cast ‘Heat’ and ‘Aphrodisiac,’ and then used ‘Sensitivity Adjustment’ to crank her sensitivity to a legendary three thousand times its normal level.
”—!!? Nbu-oooooooooooh! Gasp, a-hiiiiiiiiiiiiiiiin! Wha… what is… ha-hii, hiiiiiiiiiiiiiiiin! You’re just sucking them, you’re only sucking them, but I’m—I’m gonna cuuuuuuuuum! It feels so goooooood! More, give me mooooooooooore!”
Her restricted body, unable to move its four limbs, bounced like a young trout. Because I raised her sensitivity, she was dripping a massive amount of Love-juice and spraying a spectacular fountain.
”A-hik! Ha-hik! This is amazing, too amazing! More! Do it more! Hinyaaaaaaaaa-an! I’m c**ming againnnnnnnn! My head is going pure white! The pleasure won’t stopppppppp! I can’t stop cumminggggggggg!”
It was a magnificent Ahegao. While her eyes were rolled back, tears were flowing, and she’s dripping snot and drool, her face was overflowing with delight and ecstasy.
”Ihiiii-in! More! Do it more! Put it in! I want it, I waaaaant it! Give me more of that tentacle c**k! Ahiiiiiiiiiiiin!”
It’s a four-hit combo of slut-ification, so it’s only natural. Now then, I’ll insert it as requested. But which one should I put it in?
’Which one do you want?’
”Both! I want both! My p**sy, and my ass-p**sy too! Make it gyuju-gyuju-jyupo-jyupo!”
’Understood!’
Two tentacles-their tips shaped like glans-stabbed into Mashiro’s p**sy and anus simultaneously. Even though I didn’t loosen them up, the reason they entered smoothly is probably because she loosened up from c**ming so much.
”Ohiiiiiiiiiii-in! It’s hereeeeeeee! My p**syyyyy! My ass-p**syyyyyy! Ahi! Hyugo! It’s too much, it’s too muchhhhhhh! Pound me! Pound me moreeeeeeeee!”
Being inserted into simultaneously, she let out cries of delight. What a voice. I’m glad the whole room is completely soundproofed. The tentacles inserted into her p**sy and anus thrust in and out simultaneously. Every time she was thrust into, she orgasmed, let out a cry of delight, and sprayed like crazy. I wonder if she’ll be okay with dehydration? Well, since the mucus of the tentacles is absorbed on its own, hydration isn’t a problem.
”Hyugoi-hyugoi-hyugoi! This is my first timeeeeeee!”
’It’s not just this yet.’
”Fue? Ahi! Hahi! The tentacle that went into my ass-p**sy! It’s climbing up and up! My internal organs are being violated! But, it feels goood! This feels gooooooooooood!”
The tentacle went from the large intestine to the small intestine. Furthermore, it passed through the stomach, violated the esophagus, and then.
”Nboooooooooooh!”
It broke through into Mashiro’s mouth. Looking at the tentacle growing out of her mouth, Mashiro narrowed her eyes happily, as if it felt good.
”Nbuu! Nbooooooh! Ogooooooooooh! Ubu! Ibuuuuuuuuuuu! ‘He’s violating my very organs. All of me, everything inside my body is being raped by My Master! It feels so good… I’m going to become a total addict. Ah, I’m c**ming again! He’s raping my guts and I’m c**ming over and over!’”
Mashiro, you really are a pervert. She was aware of it herself, though. That said, there’s still more. I temporarily pull out the tentacle that was violating her p**sy, and the tentacles that literally transfixed Mashiro entwined together. I put the tentacle, which has simply become twice as thick, against her p**sy and pierced her.
”Nbu-hiiiiiiiiiiiiiiiiiii! ‘It’s so thiiiiiiick! It’s grinding against my v**inal walls while pounding my womb-neck⁴! Aaan! It’s too much, I don’t even know what’s happening anymore! It feels too good! Yes! It’s so good! Now that I know this… I won’t be able to go back anymore!’”
It’s a bit bad if she can’t go back. But messing with Mashiro is fun, you know. I bring Mashiro, who is still suspended in the air, in front of me-that is, the eyeball-and make her do an M-shaped leg spread to do a behind-the-knee-job; I also make the tips of the tentacles restraining her hands into glans to make her do a handjob. While I’m at it, I pass them through her armpits to do an armpit-job too. Furthermore, I bring her small b**bs together and pass a tentacle through the cleavage. Even with small tits, a paizuri can be done if you try. Mashiro isn’t exactly flat, after all. With this, Mashiro is s*xually processing me with her entire body.
’My body, all of it is being used… it’s being used like a tool. Normally it would be a humiliation… but I’m happy because I feel like I’m serving My Master. Ah, it’s because I realized the moment my internal organs were pierced that I belong entirely to My Master. The Master, My Master, please use this Mashiro’s entire body without hesitation.’
Yeah, she’s fallen. I’ll use you even without being told. Well, the reason she didn’t have a mental breakdown was because I had applied the slut-ification combo. If I did tentacler**apewithout applying anything, a mental breakdown would be a sure thing. By the way, the two former livestock stopped before they broke. Actually, I’ve done tentacler**apeto Honoka too, but since she underwent Training to accept anything as long as it’s erotic, there was no worry of her breaking. Though, it did take time until her comeback.
The tentacles violating Mashiro start to twitch. Since the sensations of each and every tentacle are linked, I inevitably reach the end faster than usual.
’Mashiro, I’m going to e**culate.’
’Yes, please! Cum for me! Stain me in My Master’s colors!’
Gush! Splash-splash-splash! Gush-gush-gush-gush! Throb! Whoosh! Gush-gush-gush-gush-gush! Splash! Gush-whoosh! Whoosh!
I e**culate all at once. Drenched in a massive amount of seed, Mashiro is dyed in white turbidity. Additionally, because the amount is what it is, her stomach bulges out.
’Fuahhhhhhhhhh! It stinks! It stinks, but it’s a very good smell. Ah, being wrapped in My Master’s seed… how happy am I. To be able to become completely My Master’s thing and become this happy… I never even dreamed of it. Haaa, so happy…’
Until now, it was a relationship with a sense of just being a fuck-buddy. But by being violated even inside her body, Mashiro became mine as a faithful female Servitude in the true sense.
’Shall we continue?’
’Yes, of course. More, moooore, please violate me. Please make me c**m over and over. My Master, please use me too. Soil me, break me, fix me, and then soil me again, a lot, a lot.’
That day, I enjoyed Mashiro’s body to my heart’s content all night long.

Result Report.
Ten days have passed since then, and I have finally recovered enough to write this entry. The afterglow still remains. But that sweet time isn’t something that can be forgotten so easily. Come to think of it, I hear Narumi-san also required about five days until the afterglow completely disappeared. The euphoria of becoming My Master’s thing, and above all, that pleasure. Who could possibly betray My Master, who gives such things? Even so, I am me. I will likely continue further exploration, knowing the unknown and eliminating fear. Ultimately, to be Predated by My Master and become a part of My Master-that is my wish.
Supplement.
When I begged for tentacle play once more, I was refused. On top of that, I was banned from s*xual acts for one month. Incomprehensible.
===
Honoka “I also had a hard time after tentacle play because my body wouldn’t listen to me-. I want to do tentacle play again but… it seems like I won’t be able to do normal s*x with Goshujin-sama anymore, so I’ll pass. Ah, I certainly recovered in about five days, but there was no such thing as a one-month ban. Because I’m Goshujin-sama’s dedicated female Servitude! I have to keep my physical and mental condition in order so I can be Goshujin-sama’s partner anytime!”
Mashiro “…Incomprehensible.”
Next time is Honoka’s Training. The time period is a story from while Natsumi and Honoka were dead.

Used to be Hidaka’s obsession, later violated by Sugita, which left her furious and tightly protective of the protagonist. Bashful smiles, but the second anything touches him she goes nuclear.
