kerosenecrushh! 🔞 @kerosenecrushh.bsky.social · Oct 17

Hi ppl, I just officially migrated from twt and thought I’d introduce myself :3

I’m Kafka, aka kerosenecrushh, and I write fanfic! My main fandoms are Bungou Stray Dogs and My Hero Academia and (just a heads up) 99% of what I write is smut.

To be honest, Mirio hadn’t given much thought to the idea of tentacle sex.

Bakugou’s jaw ached.

If there are any zoologists out there reading this, I apologize for my horribly inaccurate octopus anatomy.

The afterglow was slimy and sticky, and Mirio was fully covered in little red hickeys, but neither of them cared. The tentacles slowly slunk back into Tamaki’s body as they held each other and breathed.

And then, wrapped in the embrace of octopus tentacles and human skin, Mirio shuddered and came. Tamaki couldn’t hold back much longer, and was quick to follow with a small whimper.

Tamaki swallowed the end of the sentence in a passionate kiss, breaking it only to murmur back, “I love you, too.”

“Does it feel good?” Tamaki asked shakily, still thrusting in slow and deep.

“/So/ good,” Mirio sighed, arching his back. “I love you so much.”

“More,” Mirio mumbled against his lips.

Another tentacle joined the others, sticking to the bare skin of his waist. Yet another one, this one much smaller, caressed his ear with sticky kisses.

Tamaki breathed shakily as he thrust into Mirio. Even like this, with strange tentacles growing from his body, he was beautiful. His hair was falling in front of his eyes, so Mirio reached up and brushed it aside. Tamaki leaned down to kiss him.

As Tamaki lined himself up and started to push in, another tentacle grew from his shoulder and wrapped itself gently along Mirio’s upper chest and neck to stimulate him there, too.

Mirio moaned and let his legs fall wider. It was like a dozen of Tamaki’s mouth, all over him where he was most sensitive.

Tamaki blushed, but nodded. He got to work prepping Mirio while using the tentacle on him. This time, he attached it to his inner thigh, and activated whatever muscle group he did before to make the suction cups suck.

“Can you do it again?” he asked. “It feels like getting a hickey, but even more intense. I think it would feel good if you fucked me while doing it.”

He wasn’t sure if the tentacle would feel good inside him or on his sensitive cock, but playing with his erogenous zones like this was surprisingly sexy.

“Woah…” Tamaki said, eyes wide. “It left a bunch of hickeys.”

Mirio reached up and felt along his neck. There was a slimy residue left behind, not unlike saliva.

Mirio let out a soft moan. It felt a lot like Tamaki kissing his neck, only in multiple spots at once.

The suckers detached themselves with a series of wet pops.

“I think I can activate the suction cups if I focus,” Tamaki said. He laid his tentacle across Mirio’s neck and this time when he pulled away, the suction cups latched on and sucked at his skin.

Oh, /this/ felt good.

“I’m not sure. It feels… different.” Mirio avoided saying “weird” for fear of making Tamaki self-conscious about his new body. Besides, it wasn’t exactly /unpleasant/, he just couldn’t imagine it feeling good sexually.

Curious, Mirio reached out to run his fingers down the length of the new appendage. It was slick and slimy to the touch, and vaguely sticky. The suction cups were even stickier, clinging to his skin briefly as he pulled away.

“What do you think?” Tamaki asked.

Tamaki’s arm rippled as it lost its shape and became floppy and grey. The length extended, curling and tapering where his hand used to be, and suction cups popped up on the side facing inward to his body.

And he was blushing, but comfortable enough to not cross his arms over his bare chest.

“Are you ready?” he asked, ever the gentleman.

Mirio nodded.

After eating, the two of them fell into bed together, all soft touches and kisses as they fumbled out of their clothes. Tamaki was gorgeous, perfect in every form. He was pale and skinny, perfect to mark up and love.

Dinner was takoyaki, and it was even more delicious than usual when flavored with anticipation. The fried balls melted in his mouth, perfectly chewy and savory. It was just from the usual street vendor, but there was something special about it this time.

But Tamaki was as kinky as he was shy, and it was he who came to Mirio anxiously asking if he’d like to try something new.

He probably should have, considering that his boyfriend’s quirk allowed him to take on the features of any animal he ate. It was the perfect quirk to use in bed! But nope, he just never wound up fantasizing about it. Tamaki was hot enough in his regular human form.
