Stiles gets friendly with a Tentacle Monster.

In which Derek finds Stiles in a compromising position.

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

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

This might as well happen, right? Get possessed by an alien parasite, save the world, get fucked by an alien parasite… it’s all in the same vein. It’s not like this is any more fucked up than the rest of it.

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."

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.

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.

It starts with Sasha's neighbour worrying about the stupid fish. When Sasha finds out what's behind that, it ends so, so much worse for him... Or: Putting "ovi" into "oviposition" ;) (~8k of Ovi getting tentacle dicked down + oviposition, the fic's basically in the tags, and what is advertised there is exactly the fic, you do the math)

Jin Zixuan has been in love with Jiang Yanli for years, even if he knows she isn't human, but he knows he has no chance with her because of how terribly he treated her back in high school... or so he thinks. One night at a party they meet and end up hooking up, and uh, it might be a little more than he bargained for (but he isn't complaining).

Kon is in desperate need of a bit of relaxation. Maybe his method of choice is a little unconventional, but hey, getting fucked until even his Kryptonian biology is exhausted is a harmless way to get there.
