Chapter 410 Sister-in-law After a Long Time ②*
Edited by: Kanaa-senpai
”Nchu, gulp, slurp… ♡♡♡! Ham, chu, nnghuuuuuuuu♡♡♡♡♡!!!”
The night of my reunion with Flearis, the step-sister of my love-slave¹ Lily. Having already been milked once, I was still being subjected to her relentless, feverish kisses.
”Phew…! Hey, this is a bit much for a ‘prototype’ test, don’t you think…?”
”Haa, haa… ♡♡♡! I don’t care… I’m not letting you go today… ♡♡♡♡♡! Nnchu, chu, chu♡♡♡! Lick, slurp, rero… ♡♡♡♡♡!”

Flearis declared with wide, shimmering eyes before resuming her assault. She ground her hips-or rather, her uterus-against my glans, hitting me with the full force of her love and lust.
Lily gets like this too, occasionally. In her case, she’ll let me have the first move, but then she’ll spend the rest of the night using her whole body to thoroughly exhaust me. At times like this, it’s only polite to meet them with everything I’ve got and “counter-attack.” It’s a matter of a man’s pride.
Besides, Flearis was clearly waiting for that counter-attack. If she really wanted to dominate me, she wouldn’t have left my hands free. A girl of her caliber could have pinned me easily.
”Nngh♡♡♡!? ♡♡!?”
I let my hands wander over her defenseless back, sliding them down toward her lower half. On the way, I grabbed and kneaded her butt cheeks, and the moment I reached the |des|ti|na|tion|, she reflexively arched her back. But I wasn’t about to stop there.
”B-Big brother!? N-Not there…!”
”You’re free to do as you like, right? So I’m going to do the same.”
”Y-You’re so… ♡!”
Flearis feigned a protest, her voice sounding strangely gleeful. Ignoring her, I began kneading the area around her anus with my fingertips. I felt for the folds of her “chrysanthemum gate,” stretching them out and gently tapping the center. Tap, tap. Just like encouraging a kitten to do its business. It was a ritual to summon him.
”Fuu… ♡♡♡! Nn, chu, chu… ♡♡♡!”
Flearis desperately constricted her anal sphincter, trying to focus on the kiss. As a side effect, her v**ina tightened too, which felt incredible. But she couldn’t keep that tension up forever. As I persistently stimulated her wriggling, itchy backside, my finger eventually brushed against something smooth.
It was our shop’s popular item: “Slime-kun Who Dwells in a Woman’s Arse”². It seemed Flearis had been faithfully “rearing” her Slime-kun even while we were apart.
”Ah, n-no♡♡♡!”
Flearis let out a panicked cry as she realized he was peeking out, but there was no stopping it now. Slime-kun was ready to leave his cozy nest and journey into the outside world.
As Flearis fought back by tightening her anus, Slime-kun went through a cycle of Pop!-poking his head out-and Zip!-retreating back home. Pop! Zip! Pop! Zip! Eventually, her anus began to loosen, or perhaps she simply ran out of strength, because his retreat slowed from a Zip! to a sluggish smuuuush…
”Aaaaahhhhh… ♡♡♡♡”
Flearis knew it, too. She clung to me, letting out a pitiful, tearful wail that practically begged for mercy. Given that her “back door” had been used countless times during our “experiments” and she’d learned to enjoy it, I felt she didn’t need to resist so much… but I suppose a maiden’s heart is a complex thing.
Naturally, that didn’t mean I’d go easy on her. I pinched the tip of Slime-kun as he poked his head out. He tried to slip away, but after a few tries, I managed to get a firm grip.
”B-Big broth-GGHHHAAAAAHHHHHH♡♡♡♡!? ♡♡♡!?”
SLUUUURRRRRRPPPPP!!! Wow… she really grew him into a big one… As I yanked Slime-kun out with all my might, she let out a low, distorted scream, as if her very soul were being dragged out with him.
Her body stiffened, bucking and twitching as beads of sweat erupted across her skin. It was impressive that she managed to keep clinging to me, but I noticed her secretly bearing down to crush her own uterus against me.
”Hooghh… ♡♡♡ Ohhh… ♡♡♡ Ooooooh… ♡♡♡♡♡”
”That was quite a lot, wasn’t it?”
”P-Please… stop… saying it like that…”
She replied in a genuinely embarrassed voice as I admired the thick Slime-kun she’d just “produced.” I kissed her neck and coaxed her with a “Sorry, sorry,” and she eventually softened with a “W-Well, I guess it can’t be helped… ♡.” She really is cute.
Well, that’s one thing, but I was still going to dig into that hole. I thrust my middle and ring fingers into her now-pliant anus. It was soft, warm, and slick.
Using my fingers and my c**k as anchors to support her weight, I reached for the item I’d prepared by the bedside. Every time I shifted, Flearis let out an “Ohhh… ♡♡♡.” Finally, I secured the target and pulled it back.
”B-Big brother, what is that…?”
”It’s the ‘Anl-Digging Grub (Temp)’”³.
”Huh…?”
”The ‘Anl-Digging Grub (Temp)’.”
”N-No, I’m not asking for the name…”
”The name tells you exactly what it does, doesn’t it?”
”Ugh… I-I think I get it, but I also don’t…”
”It is a pretty terrible name. If it doesn’t sell, I’ll change it.”
”W-Why are you being so stubborn about telling me what it actually does…?”
Because I wanted to enjoy her fresh reaction, obviously. Without saying that aloud, I began coating the “Anl-Digging Grub (Temp)” with our anal lubricant, “Morning Dew of the Chrysanthemum”⁴. Before she could start resisting, I took aim.
”It’s going to be a bit chilly, okay?”
”Eh? Ah, hyah♡♡♡!”
”You okay?”
”I-I’m fine… but… ♡♡♡”
As I pressed the tip against her anus, she let out a cute little yelp. I let the lubricant do its work, slowly sinking the “Anl-Digging Grub (Temp)” into her. Her anus had been thoroughly broken in during our previous “experiments,” so she swallowed the whole thing with ease.
”Haa, haa… ♡♡♡”
”Nn, you took it like a pro. Does your stomach feel okay?”
”Y-Yes. Thank… you… ♡♡♡”
She thanked me while rubbing her skin against mine, even as I was unceremoniously stretching her back door. I’m not one to talk, but she really should be more on guard.
Her sister Lily would be glaring at me with suspicious eyes and complaining in a low voice right about now. Then again, Lily gives in pretty quickly too, so they’re about even in the “pushover” department.
”Um, so… so far, it feels just like a normal ‘Anl Ddo-Buddy’…”
”Yeah, for now.”
”…What kind of special features does it have?”
”Patience. You’ll find out in a second. Alright, turning it on.”
”Eh!? Wait, I’m not ready-OHHHOOOGHHHH♡♡♡♡!? ♡♡♡!”
The moment I clicked the switch on the base, Flearis’s back arched in a violent spasm. As she’d noted, the “Anl-Digging Grub (Temp)” looked like a standard “Anl Ddo-Buddy” with a safety stopper to prevent it from getting lost inside.
In reality, it was a modified version of our new “Wriggle Ddo-Buddy.” Which meant that right now, inside her anus, the “Grub” was squirming and writhing, burrowing into her intestinal walls.
”Ho, hooh… ♡♡♡! T-This is… ♡♡♡!”
”A spin-off of our newest product. How’s it taste?”
”It’s incredible… but… w-what is happening…!? Ngh… ♡♡♡!”
Flearis looked utterly bewildered as her insides were being scraped. Every time it hit a sensitive spot, she let out a vulgar, distorted moan. I could feel the vibrations through the v**inal wall, reaching my own “Ddo-Buddy.”
”Alright, I’m kicking it up to level two. Enjoy the ride.”
”Wai… ♡♡♡! Ahh♡♡♡!”
As the switch clicked into its second position, the second round of my night with Flearis truly began.
