Once upon a time, a woman fell in love with a man that she thought was actually a man. Turns out, fucker was a shape shifter, and not just any shape shifter, but a chaos monster. Fast forward a few hundred years, and one Stiles Stilinski is minding his own damned business, helping his pack defeat an (the? He doesn't know, he just knows they're assholes) alpha pack, when this witch starts laughing at him. And suddenly he has tentacles. In which Stiles discovers he's actually a baby chaos monster, sprouts tentacles, and then has to spend an indefinite amount of time with one rather surly alpha werewolf, learning how to control his form, defeat an alpha pack, and navigate the perils of loving someone who's kind of afraid to be loved. All while sporting tentacles that have a mind of their own. Easy, right?

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

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.

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."

A very specific part of Jin Ling's Yunmeng Jiang heritage makes itself known when he comes of age. His friends help him out.

Edgar has wanted to be a member of the Choir since he first learned of its existence, and he finds himself inducted into its ranks in the most unusual of ceremonies.

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