I'm so stupid. We've been in the dungeon for days now, trying to find anything valuable. But we haven't found anything good yet. So when we got to a big cave, we decided to split up to cover more ground.

First, we went in pairs, but the cave was so massive that my partner and I decided to search a big ruin separately and meet outside of the structure either when we found anything or if we searched everywhere without finding anything.

And then there was this room that looked pretty good, still. It had some furniture, some silver cutlery that I put in my bag to sell. I searched for any threats first, of course. So when I saw that chest... I didn't think much of it.

So stupid.

I opened it without checking it first and... it was already too late. One tentacle shot out, wrapped around my mid-section and pulled me in. I couldn't even scream before it closed above me, trapping me in the darkness.

My flailing arms and legs were soon held still by more tentacles. And now here I am, incapacitated. Will this thing kill me?

I stopped struggling, to try and preserve energy. But when I feel tentacles slither into my clothes, I try to get away again. Pointless, of course. The tentacles push my shirt and vest off and do the same with my pants and underthings.

I notice a difference between some of them. There's smaller ones that work almost like fingers and - fuck! One just wrapped around my right nipple. Fuck. They're not going to...? Are they?

There's thicker ones, like the ones holding my arms and legs. They're strong, I can't escape them. I feel another small one slither around my left breast. The tip starts teasing my nipple and they get hard, to my humiliation.

The space is tight, my legs are folded, but the mimic still pries them apart with the tentacles. This thing has done this before, it must have.

The tentacle that slides between my legs is slippery, unlike the others. I know what this means. I know why this mimic has lubed up tentacles. It doesn't go for my pussy and I clench my ass against it, trying to keep it out. But it's useless. The slippery thing pushes past my asshole. Just an inch and it stops, keeping my ass spread around it.

I moan, "fuck!". I've never had anything up there. It feels better than I thought. But my hole isn't used to the intrusion and I'm sure it's only able to get inside so smoothly because it is so slippery. I feel every bump and ridge as it slides deeper after a moment. The tentacle get's thicker, too, spreading me even more.

My hips start moving on their own, trying to get away. Away, of course. But the tentacle is relentless. It goes deeper and deeper and I feel it inside of me deeper than I thought possible. I sigh in relief when it stops. I'm so stuffed.

The tentacle just stays there, not moving. A moment later, one of the small ones slides between my legs and starts teasing my clit and another one, a mid-sized ones, nudges my pussy.

"No! No, fuck, no!" I scream, but a tentacle sides into my mouth and gags me. It's moving slowly in and out, never leaving my warm mouth as it's companions start rubbing my clit and my cunt and all I can do is moan and wriggle.

My ass is so stuffed and I scream around the tentacle in my mouth, when the one at my cunt starts pushing inside, slowly, so slowly, filling me even more. All my holes full now.

It's torture, how slowly they're fucking me. The one in my cunt moves so slow, I feel everything. How my pussy is starting to get so wet it drips out of me. How my ass clenches around the intrusion. How good the tentacle in my mouth tastes. My nipples are pulled and played with.

It feels like an eternity until, finally, they pick up speed. Not much, but enough to provide at least some stimulation other than clenching around the intrusions in my body. I'm panting into the darkness.

I shouldn't enjoy this, but I do. The torturously slow fucking I receive is better than nothing. We haven't found anything in this damned dungeon. My fucking partner jerks off every night, grunting and groaning, making noises that, in turn, make me wet but he's been denying me, telling me it would only strain our 'partnership' - leaving me wanting.

And now, these long and thick tentacles that penetrate all my holes feel like heaven. Fuck. I even enjoy the one in my ass. The stretch should hurt, it's much more than I shoult be able to take for my first time getting fucked in the ass. But whatever makes the tentacles slippery is making me horny and wet and desperate, too. Must be aphrodisiac. I'm hot, my nipples are straining and my back arches, trying to get more friction.

The mimic must be picking up on my desperation, because it starts fucking my holes harder, faster. Pulling out of my ass as the other tentacle is slamming into my cunt and pushing deep into my ass when the tentacle in my pussy pulls out - only to repeat.

I'm sure I'd be begging and sobbing if there wasn't a tentacle fucking my throat, pumping me full of whatever aphrodisiac the damned thing is producing. It tastes so good, like candied fruits and heavy mead.

I need to be fucked like this. I need it.

And just when I fall over the edge, holes clenching violently around tentacles, spine bowing, the mimic is thrown open and not only my partner, but a whole dungeon party look down on me. Stuffed airtight as I am, my screams muffled as my ass and cunt are pumped full of cum. So much so that it starts gushing out. Obscene noises echo in the room.

They're all watching me clench and mewl, some horrified, some amused and even aroused.

"You really are such a whore" he mutters, but starts rummaging around his pack for some glass vials. "At least mimic cum has a good market value. I've found us a party for the way back, by the way."

Asshole.

My thighs quiver. The tentacle in my ass still pumps cum into me, I'm drained and, judging by the looks of my partner and the others he's found, I'm going to be used as a breeding bitch to this mimic until we're out of the dungeon.

The thought sends me into another orgasm, which triggers the mimic to pump me even more full and my eyes roll back. I notice that the party shuffles around, lifting the mimic while I'm still impaled and captive in it. They're taking the whole thing, I think.

Nobody made any effort to get me out. They really are going to let it fuck me and gather the cum to sell.
