Arachne's Hidden Toy
"So this is... that rumored thing," I muttered, watching her eyes sparkle with anticipation instead of fear at the sight of the writhing blue tentacles. I couldn't even bring myself to sigh. How did such a perfectly pretty girl end up like this?
"Can you shut her up for me?"
"Ughup..?!"
They really could move far more freely than I'd imagined. I had kept them sealed away ever since I first summoned them. The blue tentacles lifted her slightly, binding her in place while slowly dissolving the fabric wherever they touched, exposing her pale skin.
"Come to think of it, it was the same last time, wasn't it? Wearing a bunny suit under your suit like you were having fun all by yourself."
"Uguu... huu..."
"You were probably excited, wondering when I'd catch you this time too, right?"
Her clothes had been thin to begin with, and with so little fabric, they melted away in seconds. Only a few scraps remained before she was left completely naked. I positioned myself behind her. Now I could see it clearly—the reason Undine's tentacles had been so well-behaved instead of immediately targeting her rear hole.
"...A ring?"
Below her already slightly parted, lewdly glistening folds, where her anus should have been, sat something that looked like a bathtub stopper... complete with a ring large enough to hook a finger through.
"Haa..."
So she really had been keeping something stuffed inside her the whole time. Seeing it directly made me feel a little dizzy. She had let me say all those embarrassing things while she was in this state, pretending to be perfectly composed on the outside.
Smack!
"Huuup..?!"
Annoyed, and irritated by how tempting her ass looked, I gave it a hard slap. The crisp sound improved my mood a little. A reddish handprint bloomed across her white skin. I knew I shouldn't feel better from something like this, but she was the one who had done this to me.
"Let's see what kind of toy this is."
"Uup... guup.."
She barely managed to turn her head toward me, her eyes glistening with pleasure. I hooked my index finger through the ring and pulled gently. It didn't come out as easily as I'd expected.
"Hmm..."
Maybe a little harder. A fleeting rational thought warned me to be careful, but stopping now would make it seem like I was scared. So I pulled.
Pop-pop-pop-pop!
"Uguoh...! Ooh..?"
"Beads...?"
She jerked like a freshly caught fish, liquid spilling from between her legs. Since there was no plug in front, she came and squirted at the same time—an oddly rare sight. Worried the living room floor would get dirty, I watched as Undine's tentacles instantly changed shape to catch everything before it hit the ground, then another tentacle promptly plugged her front hole.
"Uo... uuut."
"Don't come without permission. If you pass out, who do you think has to clean up after you every time?"
After scolding her, I looked down at the toy that had partially slipped out and stopped. It was made of smooth, glossy black material that looked quite elastic. Several beads of varying sizes were strung along a cord, with the largest near the ring and gradually smaller ones toward the end. That explained the intermittent resistance when pulling it out.
Really... even the shape was as lewd as she was.
Pop!
"Uup...?!"
'B-back in...? Eh...? Ah? A...?'
I pushed the partially removed toy back inside her and decided to move to the bedroom first. As I'd warned, if she passed out I'd be the one cleaning up, so it was easier to only dirty the bed.
"Aue... haaup..."
'All at once... pull it out all at once... please...'
"...You really are something."
Once we were in the bedroom, what came next was already decided, yet she was still making demands. I found it impressive, but at the same time a wicked urge to make her suffer a little rose up.
"I'll pull on the count of three."
To keep her from thrashing too violently, I firmly bound her limbs with tentacles and gripped the ring tightly.
"Three."
Pop-pop-pop-pop-pop...!
"....?! ...! ..!"
I yanked it out without counting one or two. Her waist and hips trembled violently as she squirted from the front while muffled, beast-like moans escaped the plugged hole. The beads grew smaller toward the end, making them slip out more easily...
"...What the hell, why is this so long?"
Pop-pop-pop-pop... pop!
"No, what..."
I thought it would be out by now, but it kept coming. Panicking, I pulled harder until finally the entire thing emerged.
"..."
It was slick with lube, glistening and wobbling due to its length.
"You were keeping this inside you while talking to me?"
The toy, freshly pulled out, still radiated her body heat. I couldn't even imagine how it had all fit inside. But more than that...
"...This is bad."
My pants were visibly tenting from this new kind of situation. With Undine I had been on the receiving end, and with Arachne before... well, it had been a different hole. So this was something else entirely.
Thud.
Finally tossed onto the bed, she still hung in the air, limbs flailing as if she were still coming, twitching and convulsing in a ridiculous yet blissful display. After retrieving the tentacles, I quietly stared at the warm toy still in my hand before approaching her and sitting beside her on the bed.
"...Uhh... huu, as expected... it's completely different when someone else does it..."
"You must've been holding a lot in."
"...It's really long, right...? At first, even three beads felt uncomfortable and tight inside, but now... I can take it all the way in..."
So her "preparation" had meant developing herself with these toys. She hadn't wanted to break her hymen with a toy, so she'd only played with her rear until our first time.
"Don't worry, Master. I've been fasting since yesterday, and I already did an enema..."
"Yeah... good girl. Well done."
I cut her off before she could say more—I didn't want to hear that kind of thing from a girl—but the word "enema" had already told me everything.
"You should've asked for help... or was this your way of playing a prank?"
Squelch...!
I pulled out a single tentacle and shoved it between her twitching anal folds. She shuddered again at the cool, smooth sensation. Sorry, Undine, but this cleaning tentacle that devoured everything from dead skin to impure thoughts was truly a specialist in anal preparation.
"A... aaah... even inside... uwaang..."
With this, I could do it anytime, anywhere from behind... No, wait.
"I'm sorry for playing a prank... But I still wanted to give you my first time back there, Master."
"..."
Her suddenly shy tone was a little funny.
"Well, your first time back there wasn't with this thing? The second was with Undine."
"...Uwaaang..."
I lightly shook the toy that had just been inside her, sending globs of lube splattering onto the sheets. Instead of being hurt by my cruel words, she only gave a broken smile, as if she didn't know what to do. Only she could react that way.
"I should take my clothes off too. Since it went in so deep, this works out nicely."
"Ah...?"
Her expression stiffened for a moment when my erection sprang free, almost as if it had bounced out of my pants. Come to think of it, this was the first time since Yerin.
"W-why... it looks bigger..."
"It is bigger. A lot of things happened."
She had prepared her rear hole assuming my usual size, so the unexpected discrepancy clearly flustered her.
"I-I think... if this goes in... it won't close properly..."
"So what? You like being broken, don't you?"
"No, this is... ah?"
I grabbed her tied-up hair and pulled her head down beneath my erection. Her timid voice finally fell silent. The sight of her trembling eyes beneath the shadow of my shaft was quite satisfying.
"So, should I just put it in? I don't mind. Nero's probably grinding her teeth downstairs right now. If I ask her to take your place this weekend, she'd probably be thrilled."
"That's too much... kiss."
"..."
She complained it was too much, yet kissed my shaft as if it were the most natural thing in the world. I was speechless, but apparently that was her answer.
"What are you doing? I'm going to put it in right now, so stop lazing around and get on all fours."
