41 Is having sex with living clothes on a threesome?

The spreading veins disappear as quickly as they came, settling into the fabric as if nothing was of the ordinary. All I can make out in squinting my eyes are the tiny threads that make up my robes.

"Weird…"

A gentle heat envelopes my body, like I'm wrapped in a blanket. Whatever the living slime has done to my robes, it appears to react to the mana in my body and to exterior sources.

I take a few steps, swinging my arms and twisting my waist, just moving to get a feel of the new sensation. Aside from being a slightly tighter fit than before, nothing is out of place. And if it weren't for the subtle heat there is no indication that the experiment failed or succeeded.

I'm about to throw open the door to do a test run outside when something tickles my arm.

My silk and wool woven dress no longer feels smooth against the skin. Something tickles me beneath my clothes. I tug on the fabric and see thousands— hundreds of thousands of tiny undulating fibers. They brush the surface of my skin, lighting up my senses a hundred folds.

The assault doesn't stop there. Pressure pushes against my stomach. The tiny strands gather in mass, forming a tentacle that snakes down my crotch.

"No, you don't!"

When I reach for it, the tentacle disappears and reappears on my back. A shock shoots up my spine as it nestles between my cheeks and knocks on the back door.

"Wait, wait, wait. You're my clothes! Obey me— AAAAaahhh!"

Lubricated by its own slimy substance, the appendage penetrates my asshole. It settles there, seemingly content with being inside.

"Nnnhh… fuck… it's so big…"

The fabric on my breasts tightens and begins to vibrate. I'm not given a chance to recover. My already stimulated nipples make my knees weak, and I collapse.

"Mistress, doesn't look good?"

Gurk rushes over to help, but his touch excites me further. Having sensed my arousal, he demonstrates his own by rubbing his erect member on my thighs.

"Now isn't the time, I'm… aah!"

Another slimy appendage teases my clit. I keel over clutching my stomach, a sudden impact knocks the wind out of me. The tentacle in my ass throbs, pushing me into an orgasm.

"Cumming… nnhh… oh, god…"

I try to pull it out, but it's lodged in deep. That's when I notice that— glancing at my clothes again— that the material is becoming transparent. It's transformed. No longer the familiar academy robes I've worn for years, but an erotic lingerie outfit.

Somehow, this is more embarrassing than being naked. There's an opening in my panties in the front and in the back. The bra— if it can even be called one— are vertical bands of cloth that barely cover my breasts.

My goblin can't help himself anymore. He climbs on top of me, still on the ground recovering from the orgasm of getting my ass plugged. I can't wait anymore either, so I grab his dick and guide it to the entrance of my pussy.

"Yes! Fill me up, baby— aaahh!"

Gurk plunges deep, unimpeded thanks to the opening in the underwear. The pressure of having both holes penetrated, pushing and scraping inside drives me crazy. So intense are their thrusts that I cum a second time.

"So… hot… nnngghh… aahh, mmm~"

A few more rounds of sex and the stimulation from my clothes becomes too much. Every inch of skin in contact with the hair-like bristles has become overly sensitive. It's come to the point where every time Gurk slaps my ass, it triggers a mini-orgasm.

"Mrauu!" Rio comes through the front door and tilts his head.

"H-Help…" I beg.

"Nyau~"

And then proceeds back out the door.

"Riiooo— eek!"

Gurk's spurts another hot load into me. As I crawl my way to the cauldron, I pass by the mirror and see the clothes transforming again. This time, I'm completely naked with the exception of a pair of feline ears on my head, and a black tail whipping back and forth. It wags with a mind of its own, falsely pretending to display my excitement like I'm a bitch in heat.

"These stupid… what kind of dumb joke is this?! Ahh! Gurk, haven't you had enough?"

Encouraged by the abrupt change in outfit, Gurk picks up speed. When he grabs the tail, my ass jerks up with it. He tugs hard not realizing that he's fucking my ass with the clothes-turned-tail.

I manage to grab a slumber vial from the shelf and break it open at Gurk's nose. He falls asleep, ejaculating one last time before slipping out of me.

I stand up, pussy dripping with cum and legs trembling. The tail continues to wag, mocking me from my ass. As if it hasn't had enough already, it reforms, extending spikes in all directions like a sea urchin.

"What… now…waah—!"

I'm thrown back. The spindley appendages have latched onto and fastened me to the wall. Spikes thicken to elastic tentacles that explore my body, searching for a hole to plug up: my pussy, ass, and then my mouth are stuffed.

It's the anoragrathi incident all over again, except I'm being penetrated by a pseudo-living organism in my clothes. No one is here to save me, and I can't call for help with my mouth stuffed.

"MMrpph— shllrp… shllrp…"

Natural lubrication from the tentacles give it free rein to thrust into me. Everything is starting to feel good. It's not often I get fucked in my ass and pussy at the same time. Even as I orgasm, it doesn't let up. It continues to screw me into a state of bliss.

"Raaa~"

Red comes through the door. I try to gesture her to help me, but my hands are firmly stuck against the wall. She comes over on her own to inspect my crisis, but the tentacles capture her as well.

"Grrrr… maaaa!"

She swipes and claws to no avail. The durability of the material has toughened to the point of being impervious to regular physical attacks. She's quickly entangled and is brought ass first to my hips.

The tentacle in my mouth retracts and slithers down to my hips, joining the one at my pussy. A familiar sensation, much like the time I had the tennoraphallus in me grips my waist. My body pushes forward on its own and thrusts into Red's pussy.

"RAAAAaaaahh!"

"I'm sorry! Sorry— ahhh!"

Her inside is so wet, fleshy walls clench around my synthetic penis. I can't believe I forgot about this feeling. I'm having sex with a harpy, thrusting into her like I'm trying to impregnate her.

Red spins to face me, her legs clamp around my waist now that I'm freed from the wall. We embrace each other, our lips meet in a passionate kiss. When I push my tongue into her mouth, sharp incisors scrape lightly against it.

I've come to learn a lot about the harpy sisters. Each of them has a unique personality: Blue loves to kiss and give pleasure; Green wants nothing more than to be spoiled like a baby; Red is the most insatiable of the three, enjoying sex so much that she's sometimes a bother to the other two.

Red's bounces restlessly, her waist clapping loudly against mine. I have a hard time meeting her thrusts. I don't need to, eventually she rides me to an orgasm— nothing spurts out, but my cock throbs with an intensity that reverberates back to my pussy.

"I'm cumming, Red… nngh… Aahh— ahhhh!"

Our lovemaking continues at every corner of the great hollow, trying every position without rest. Unlike a normal penis that gets soft or needs time to recover after every orgasm, mine isn't physiologically the same, and so I'm able to keep going. Red delights in my new organ, but eventually she passes out and drops to the floor twitching.

There must be a way to get this off. If it reacts to sources of mana, then…

I grab a magic crystal from the basket and toss it on the floor. The robes unbind from my skin and launches off to consume it. I throw a box over it, but it slips out from the cracks and reforms on my body.

"Oh, come on! I thought I was being clever..."

Fortunately, it settles down after absorbing the magic crystal. The ears and tail reforms to my normal academy robes and lies dormant, unchanging.

"Hmm…"

I grab a handful of crystals and stuff them into my robes. Glittering stones embed and then dissolve into the fabric. A pulse of energy ripples across the surface, but nothing more happens.

Strange. I thought the acidity trait wasn't inherited when I added slime extract. Perhaps it's not dissolving because it outright absorbs the crystals. It gives me an idea to feed it a soul stone, but that might not be a good idea.

I'm able to undress without resistance and put on something else for now. Suffice to say, the experiment to imbue my robes with living slime is a success. It required a lot of valuable reagents— and two willing sacrifices— but the outcome is worth it.

"Now onto the important matters…"

I should answer King Marcus' summons by departing soon. The faster we get down to discussing details, the better. Parthun's greatest defense is to play the fool and pretend that I have everything under control. That way, Headmaster Anora won't feel inclined to beseech the Council of Kings to invoke the Rite of Cleansing. She won't take that seat unless I capture either Eudora and Mira. Without either of them, she has nothing to bargain with.

Over the next two days, I work alongside Clem and Kati to ensure our settlement is fortified and defensible in my absence. A surplus of potions have been brewed for their benefit in case it ever comes to it. I'll only need to bring a few restoration potions and stamina draughts for my journey.

My primary concern is if Eudora decides to lay siege to Ellowyn. Though she hasn't attacked yet, we would be fools to think we're safe out here. The demihumans may be many and strong, but they've never fought the witch who toppled an empire.

While I'm instructing the kobolds on how to create bombs by combining Miuna's slime and magic crystals, Kati alerts me to follow him to their side of the settlement.

"Something is happening to the guardian tree. Queen should come see!"

It isn't just the kobolds who have gathered, but also the orcs and women as well. The tree was fast becoming a symbol of hope to the residents. To see something grow in leaps and bounds before their eyes is a reminder that they could always rebuild after losing their homes.

My heart fills with joy seeing what was only a sapling a week and a half ago, is now a full grown tree. Just like before, I'm drawn to it. The tree whispers in an indiscernible language that I can only understand through sensations.

The many buds on the tree begin to open into beautiful flowers that adorn its branches. An array of colors, like a vibrant field of tulips on a single tree, blossoms to my approach.

"If only Flora could see you now. Part of why I'm here— the potions and elixirs I can make, is thanks to the boon she gave me."

I place a hand on the tree. It pulses, then something pushes against my hand. I take a step back as a figure emerges from the trunk. A child, barely at the height of my waist, pops out and falls into my arms. She looks up at me, her face as green as leaves with hair decorating long, vine-like hair.

"F-Flora…?"

The newborn dryad tilts her head and says, "Mama?"
