A Polite Bite

Trigun

A Soft Place to Fall

Wolfwood takes care of Vash after he gets drunk.

won't you stay with me my darling? (when my walls start burning down)

Vash is having a mental breakdown with traveling in the desert with Wolfwood. Maybe some cunnilingus and bondage will help.

Vash and Knives are huge alien angels. Wolfwood is supposed to be a sacrifice to them, but Vash saves him and takes him for himself.

Happy reading!

the best fanfiction you've ever read was written by a woman in her 40s before she made dinner for her kids. it was written by a teenager after school when they should've been studying for a history test. and a barista came up with the idea while they cleaned the espresso machine and busser fact-checked it on their break and the post-doc edited between writing grant proposals and the nurse apologized for typos in the notes after a long shift and behind every drabble and one-shot and multi-chapter fic there is a person with a wonderful and interesting and chaotic life and it is such a privilege that we get to be a part of it because they decided to do this thing we all share, for fun.

“And if you’ll give me 40% of the MOST POPULAR VOTE, I’ll give you my SPECIAL REWARD... A year’s supply of NON-GLOOBY SLIME!!! Never or BARELY used!!!” Tenna concluded his speech with a huge smile, jetting his hands up in double peace signs.

The crowd roared in confused enthusiasm as Tenna gave a gracious flurry of low-FPS bows, pausing only for the occasional stink-nose at his audience plants who weren’t throwing enough 3D roses.

Eventually, the room fell silent. It was Senshi’s turn to speak.

He puffed out his chest, took a long, sweeping look over the audience… and shook his head.

“I can see not all of you are eating properly.”

The crowd murmured with embarrassment.

“I don’t know who needs to hear this, but it’s time to take the turkey out of your icebox. I have seen the ingenious technology with which your people store food... and I have also seen the waste which results from such convenience.

“The food you take had a life. Beasts grew fat on the grass of the field, plants grew from the sun’s rays, and mushrooms grew from minerals in the cracks of caves. And yet, it sits in your iceboxes, collecting moisture until it perishes.

“Eat what is given to you. Because its life will make you stronger, too.”

Without another word, Senshi left his podium and stepped away from the stage. The crowd murmured in confusion. “Is he really like that?” somebody said. “I only remember reblogging the photosets of him tripping and showing ass.”

--

Back in the Green Room, Tenna wrung his antennas nervously.

“Y-y-you think they liked me!? They HAD to!! I mean, I don’t know what Asgore was thinking, getting that weird haircut and running that food waste campaign, but… YOU thought I did good, didn’t you, Kris?”

Laios nodded aggressively, a streak of blue face paint peeling from his forehead.

“You did AMAZING, Tenna! By the way, now that we’ve seen all your insider campaign secrets, do you have any more videos of Susie? Especially her tail... If I could get a look at that, I could finally tell if she’s a dinosaur or --”

THWACK. Fake antlers butted Laios’s head.

“LAIOS?? Weren’t we dressed up to help SENSHI???” Marcille hissed, gesturing awkwardly with her hooves.

Suddenly, Tenna turned to the two adventurers.

“Hey, WAIT a second. SOMETHING’s not right here...”

Laios and Marcille held their breath.

“Where the heck are my POINTS!?”

Just then, the door opened. Chilchuck took one step into the room, whistling and holding a large bag.

Everyone turned to him.

Chilchuck paused, took a step backwards, and closed the door.

“CHILCHUCK!!!” yelled Tenna.

“How come Chilchuck got to stay Chilchuck!?” yelled Marcille at the same time.

Meanwhile, in outer space somewhere, some guy was making out with a rock.

phm is decently popular in japan and i mostly see this when i check twitter and see accounts posting pictures of handmade rocky plushies that are so fucking round looking it brings a tear to my eye

[sanguine-humor]

he keeps me sane

[sanguine-humor]

btw, idk if this will be seen by any of the countless people who already have seen and reblogged this post, but heres the original guide posted on how to make the chibi-rocky! the OP also has a separate guide for a more accurate rocky, though obviously less simple of a guide than the little thingy shown off

(im surprised this post gained any attention, haha, if i had known i would have just shared the guides, the more handmade pebbles in the world the better)

original by @foxes-in-love , one of my fav comics ever now w my fav characters ever

[cosmic-starfall]

Vash is a femme, Wolfwood is a butch. Vashwood = butch/femme

Meryl is a femme, Milly is a butch. Meryl/Milly = butch/femme

Therefore:

Merylwood = butch/femme

Millywood = butch/butch

Vash/Meryl = femme/femme

And so on and so forth. Lesbian math.

[milowing]

sometimes u headcanon a character as a sexuality but then also ship things that contradict that. sometimes you ship things you would NEVER EVER want in canon. this is because these things are fun and silly and not legally binding.

[captainclickycat]

Yeah I don't know where some people got this idea that fanfic is always like, auditioning to replace canon or being posited as "better" than canon, as opposed to people just borrowing the characters to play with in the sandpit for a while before putting them back in their box
