"Alright, you've got me. Now what're you going to do?"

Gerard always knew that there had to be life on other planets. He just never planned on meeting it.

It's not all bad when Jim and Leonard awake in a strange room containing a large pool of water - until the tentacles start appearing.

"Gosh, Karkat! That's not what I was expecting at all!" Fanart drawn for Porn Battle XII.

Ghost Gauntlets + Authentic Wriggling Tentacle Dildos. Rose + Dave. It's really very simple.

John beats a thunderstorm home, Rose has melted all over the bathroom, and they make do despite the absence of their other two pieces.

He's always hidden it. Them.

As the base's resident expert on human culture, Sam had fumbled his way through some pretty awkward conversations, but even he didn't feel up to tackling the questions Bee would have once he learned that his best friend had somehow developed a fetish for alien robots.

It’s not like he lives his entire life with his bottom half a writhing mass of tentacles instead of legs, but about every ten days he has to spend at least eight hours soaking in a tub of water.

In which Derek finds Stiles in a compromising position.

A tiny green tendril curls softly around his wrist where it's resting against the wood. Stiles takes shallow breaths, trying not to move or get too excited, but—it's working, he thinks. This is going to work

Tony Stark is all about the advancement of science, but...he probably should have clued Steve in a little sooner. Steve just thinks it's a bad idea to volunteer for anything that involves Reed Richards.

It's three hours before JARVIS tells Steve that Tony is ready.

If there is one thing that dating Tony has taught Steve, it's that sometimes you have to go with the flow.

Stiles gets friendly with a Tentacle Monster.

Clint has unusual fantasies; Tony has unusual abilities. This works out in everyone's favor. (Alternately: "Consentacles!")

Steve's not sure where he is, or how he got there, or why there's a tentacle there, but at least he's having fun.

The night takes an unexpected turn when Stiles summons Derek to the greenhouse.

“A few weeks ago I would have thought you were impossible,” Sherlock begins, walking into the kitchen in his blue robe, and John – not quite catching on – wants to scoff and argue, No, actually, you are impossible, but then Sherlock continues: “But now I’d say you are improbable.” John thinks this might be flattering, if he could wrap his head around it, but he can’t – Sherlock is standing near, steaming his sun-baked-clean-sand smell, like the beach after rain, an alive smell, an other smell. It’s intoxicating, and John has been studiously avoiding it, but he can’t shift away now it’s so near. Now Sherlock’s so near. And then Sherlock ruins the probable-loveliness of his words and the definite-beauty of his presence by saying: “And by ‘improbable’ I mean ‘not yet scientifically acknowledged.’”

Sollux is invited to 'tentacle night' by his kismesis Roxy. He's a little confused when she shows up with more tentacles than him.

So this story is about the time I fucked up— [ONE of the times you fucked up] —and pissed off Shiklah, my wife. She decided to punish me with the help of a couple of her henchdemons, and kinky fun was had by all.

Midoriya Izuku was born with a quirk: the ability to summon and bind demons from an alternate plane to do his bidding. With only a few days left until the UA entrance exam and still no offensive-type demons in his arsenal, Izuku makes a desperate attempt at summoning one corporeal, a feat he had never before attempted. He'd say it was a success but, he doesn't actually know if it'll be more a help or a hindrance. Especially since Bakugou Katsuki is, well, kind of a shit.

His arm wasn't the only thing the Galra changed. They also gave him certain... needs. Shiro learns to make it work for him.

Allura is acting a little strange. Shiro is asked to help, and he accepts enthusiastically.

Tentacle Gods: do not mix with Hydra.

To get to the pollen the team needs, someone has to appease the plant guardian. Shiro steps up.

or, why Eddie Brock can never return to his favorite coffee shop

Venom indulges Eddie's weirder kinks.

When Venom was quiet, and when he wasn’t shooting giant fucking tentacles out of Eddie’s body, Eddie couldn’t much feel his presence. Occasionally there was a flicker of something: of anger, of hunger. Right now there was nothing. So maybe Eddie had pissed him off. Or—and this was a thought that Eddie had not had before—perhaps he had hurt Venom’s feelings. He lay there, staring at the ceiling and listening to the couple banging next door. She was making a lot of noise. The blood came up his neck and face a little. And then a little more, now he knew that Venom would be able to feel it too.

Eddie briefly recalls some tentacle porn he’d watched just before Venom became a part of him. The copious vines holding her up and entering her every opening simultaneously. Fluids, from her or the monster who could tell, leaking from her mouth and pussy and ass. Oh, Eddie. Venom’s thought shook him, definitely not wanting to take their tongue out his mouth, How’d you keep this from us? Eddie had to be completely honest… he had absolutely no idea how he did either. ~ That good good tentacle fuckin' that Eddie so desperately wanted.

Venom had a plan to win Anne back. Eddie vetoed that plan, because it mostly consisted of eating off Dan’s head, which Eddie did not approve of for a number of reasons. The most obvious one was that Dan was a good person who did not deserve to become a snack for the monstrous alien living in Eddie’s body. The one most relevant when considering Venom’s mostly non-existent morality was that Anne would probably not be very happy with them if they bit off her boyfriend’s head. And the final reason, the one that Eddie really hated to admit, was that he kind of really liked Dan.

Eddie is lonely, but he doesn't have to be.

The cellular union of Eddie Brock and Venom is not without consequences. Alternatively, Eddie goes into heat (or some alien equivalent of it). It's Venom's fault. "The need unfurls inside of him—doubled but easier to bear now that it is shared. He understands what must be done, has always known. It is as basic and primitive as breathing."

Things Eddie Brock flirts with on a regular basis: death, insanity, his ex, his ex’s new boyfriend, and also the alien symbiote that lives inside his body. Not bad for a loser with no game, really.

Anne and Dan want to help Eddie and Venom find a new source of phenethylamine. Did you know it’s produced by a bacterium commonly found in human genitals? That’s a FACT.

As soon Klaus realize he can make Ben solid again, Ben start to wonder about some of the experiences he never got to have alive.

When a routine hunt goes wrong, Gladio finds himself only half the man he used to be. But Prompto doesn't seem to mind. He knows all about how to handle this kind of situation. (Or, Prompto watches too much hentai and never lets an opportunity go to waste)

You can find some interesting things in those old, abandoned thaigs... ******* As a general warning: it's all 100% consensual, but there isn't a whole lot of negotiation on specific acts ahead of time, and there are a few (quickly corrected) mis-steps. Nobody gets hurt, or even actually upset, but I know that's a sensitive issue for some.

it's unlike anything, when you're lovin' me

The first time Eddie suggests they have sex, Venom is, more than anything else, extremely confused.

While the Asset is in the middle of an experimentation session with the Chem Sci department, an emergency happens in another lab. One of the other experimental creatures escaped its containment cell and the Asset is ordered to go take care of it. He's hosed off, plugged up, geared up, and sent upstairs post-haste to deal with the problem. Unfortunately, the Asset is still flush with drugs that make him incredibly aroused. When the escaped creature notices, he takes an interest. Much to the Asset's delight.

The tentacle climbs up Lan Wangji's forearm and tugs him closer. This time it's his turn to shiver. The feeling is — like nothing he's experienced. Cool and slippery, strong but not the strength of muscles. Soft. He wants to feel it all over. (Wei Wuxian accidentally gets cursed, which results in an impromptu sex vacation. It goes great for everyone involved.)

The resentful energy occupying Wei Wuxian's body like an enemy army is very interested in giving him Lan Wangji, tied up with a bow. Wei Wuxian is hoping that Lan Wangji (who is far too noble and very keen to save Wei Wuxian's misguided soul) doesn't find out about any aspect of that.

Saving people, hunting things: the family business. Modern AU: the Nies are hit by a demon's death curse, which is NOT fuck or die - it's fuck AND die, a kind of reverse cultivation curse that's usually directed against cultivation partners, destroying their golden cores little by little every time they fuck. NOT a clever curse to use against brothers! ...except that the curse comes with a chaser: its targets share blisteringly horny sex dreams every night, as a way of encouraging them to go ahead and give in to the whole fuck-and-die schtick. Awkward. So it makes sense to search for a cure to the curse, right? Especially since the cure might actually help stabilise Mingjue's golden core. Obviously they have no intention of actually boning once they've got rid of the whole fuck-and-die curse... (...for the life of me I can't remember who suggested a Fuck AND Die trope on Twitter many weeks ago - evidently it has been living rent free in the back of my head ever since, though, and so here we have some Niecest.)

Sure, getting fucked by tentacles was a rare, once in two lifetimes kind of experience. But honestly, once you went demon dick there's no going back. OR Shang Qinghua (and Shen Qingqiu) gets tentacle-fucked but Shang Qinghua is still helplessly horny for a certain ice demon.

Andre walks in on something he couldn't have imagined in his wildest dreams.

What is supposed to be a special night for them takes a seemingly nightmarish turn. (AKA the one where Nicky grows tentacles.)

The naiad moved in shortly after Sid finished his house, that first summer, a week after he filled the pool. He noticed some splashing one morning while he was eating breakfast, and when he went outside to investigate, she popped her head up out of the water, clung to the side of the pool, and hissed at him. “Uh,” Sid said, still holding a slice of toast in one hand. Dew from the grass chilled his bare feet. “Are you—hi?”

This all felt so familiar to Justin. Inspired by it wrecks who it pleases by addandsubtract.

“It feels really good,” Leddy says, almost sheepish. They’re all eating lunch at Nick’s house after training, and Leddy still keeps looking around like someone could overhear. “It's a fucking trip, like - tentacle, eggs, but. It's good. I don't know.”
