A one page comic Image 1: closeup of Jon's slit as they guide Martin's cock to their entrance. Both of them are still dressed with Martin's trousers shoved down and a bit of armor visible. M: J-Jon?! Wait, we we can't do this here. J: Are you asking me to stop? M: ...No. Image 2: full scene shows the two are in a storage closet, and Martin is wearing nearly a full suit of armor. He's leaned back against the back wall while Jon straddles his lap with their arms around his shoulders. Martin is thrusting into them, holding Jon by the base of their tail to give himself a bit more leverage. M: Oh, gods...This is so reckless, love. If someone hears... J: The sooner you fill me up, the faster we can get back to the others, right? Mmph... Just – just a bit longer, dear, please... No one will ~gasp~ even notice we're gone.

Ironically, Martin is less safe when wearing armor because Jon will jump his ass the second they get the chance. Like a cat hearing a can being opened and thinking it's dinner time.

Jon and Martin find an unorthodox way to feed the Beholding. Might as well have some fun with it 👁️💚💙

Comic page Image 1:Shot showing the foot of a massive bed, with a long tail laid over the egde and snaked across the floor. Muffled moans and wet sounds fill the air. Martin: [Muffled] Jon...please I need... Image 2: Closeup of dragon! Jon's maw in their true form, their jaw open with sharp teeth and their long tongue pushing into something. Thankfully dragons don't use their tongue to speak. Jon: Don't try to speak with your mouth full, dear. Image 3: Closeup of Martin, his lips wrapped around the head of Jon's massive cock, saliva dripping down his chin. Jon: [thinking] Gods, he's still so tight. Has it really been so long since I've had him like this? Poor thing can hardly even fit me down his throat Image 4: camera pulls back to show that Martin is upside down, laid across Jon's stomach with his face next to their cock. Jon's tongue is buried in Martin's ass, stretching him open, with their claws wrapped around Martin's thighs to hold him up. M: O-okay, okay, that's good, love! I'm stretched plenty. I'm not gonna last much longer like this... J: Then we should take a break. If you're already too sore from my tongue then my cock won't be any kinder to you. Image 5: Martin is squirming against Jon's grip, and Jon looks a bit embarrassed. M: I mean I'm gonna faint before you can even stick it in! All the blood's gone to my head J: Oh. Right, erm, sorry. Image 6: Jon wraps their claws around Martin's waist and hoists him up. Martin makes a small shocked sound. Image 7: Jon plops Martin upright into their lap, with their cock held up against his stomach for comparison. Martin watches it with stunned silence, both very excited and likely a bit scared at the fact the thing is the length of half his torso. J: You went very quiet just now, little knight. Second thoughts? M: (thinking) Oh fuck. Did it get bigger?

Image 1: A full illustration of Martin being held aloft in Jon's lap, taking well over half the length of their cock as he's fucked absolutely senseless. Martin is moaning uncontrollably, jaw hung slack and dripping with sweat, and he cries out Jon's name when he comes. Jon looks fustered as well, their eyes shut tight as they hold Martin close with their claws and tail, growling and panting as they come as well, already spilling out of Martin's ass. Image 2: small thumbnail image of Jon and Martin laid exhausted in bed. Jon is back to their half-glamoured form, still dripping with come and fluids from their slit. Martin has already fallen asleep, also a complete mess with Jon's come pooling out of his ass and staining the linens. J: We can't – (yawn) go to sleep now, dear. S-still need to…clean…zzz End

Sir Martin Monsterfuc(K)er Blackwood living his best life at the opposite end of the size difference kink.

Drawing of knight!martin and dragon!jon sat in a field kissing tenderly. Jon has their hair tied up into a long braid with little flowers wrapped into it. Martin has a single flower behind his ear and his sword on his back.

Same as previous art but in a minimalist sage and pink color palette

Throws them at you because they make me SICK

(wait, I'm sorry, give them back 🥺)

Screenshot of AO3 summary: In Your Hands by HemiDemi Summary: "I think we could help each other, if it would get you out of this weather faster." An odd grin spreads across the stranger's face. "How much for a night?" Jon blinks, then looks back towards the tavern. "Erm…I don't believe knights can be bought outright? Perhaps there are services they provide for a fee, but…" "No, doll. I was asking how much you charge. Whatever your date was paying, I can double it, surely." Charge? Doll? The hell is this man on about? Perhaps it's not too late to just endure the tavern after all. Can't get much worse than whatever this is. -- Jon meets someone new while having a night out on the town. It does, in fact, get worse.

New dragon AU fic! Hope you like hurt/comfort and possessive sex as a coping mechanism for trauma ❤️ cause there's like 10k of it.

Very much damsel kink, but with a heavy tone, so mind the tags please!

A meme redraw: Title in white border says: "sometimes like this/also like that 🐉♥️⚔️" Beneath are drawings of two photos side by side. On the left, Knight!Martin is snuggled up against Dragon!Jon's chest with a sheepish smile. In the next picture, Martin is in almost an identical pose, but with his head shoved into the mattress with Jon's massive claw cupped around the back of his head. He's sweating and panting with a trail of drool falling down the side of his chin.

Get you a dragon who can do both ♥️

Jon is sat at a small table with Captain, an orange tabby cat with one eye. Both of them are watching Martin clean the dishes, completely oblivious to their staring. Jon has little hearts and eyes around his head

Martin can tell they're looking and looks back at them. Captain starts cleaning himself to look less suspicious, but Jon is much less slick, grabbing his book in a panic to quickly hide his face.

Jon likes to stare at his cute husband, but God forbid anyone sees him do it.

Hi. I wrote a very bittersweet Valentines Jmart fic. It's very angsty. #themagnusarchives #jmart #tma

Happy TeaHolding day!
#themagnusarchives #JMart #TeaHolding

happy valentine's day! <3
#tma #jonmartin #jmart

[Screenshot of AO3] A Very Nice Thought HemiDemi Summary: This isn't the first time that Martin has been handed a tool such as this. It feels familiar enough as he turns it in his palm, inspecting the length of hide that flicks dramatically at its end in much the same way that his horse, Nessa - and Jon, for that matter - will swipe their tail from side to side to signal their frustrations. But he was never keen to use a whip of any sort, and would avoid them whenever he could. He's found that the livestock he's cared for on the estate could more often be reasoned with, if one just met them on their level. Maybe a rough and assured hand to guide them when they're frightened, but pain for the sake of it always felt too cruel. And yet... -"Right, so erm you want me to hit you?"

Got a dragon AU fic for you guys for Valentine's day ❤️ Or at least something closer to Lupercalia.

Something about mid winter just makes people horny, I guess, lol.

Drawing of Jon and Martin stood side by side with travel cups of hot tea. Jon is bundled up in a thick coat with gloves and a scarf, holding onto Martin's arm. Martin is wearing a few less layers, a shirt and a hoodie, watching Jon with a shy smile.

Two cuties on a coffee/tea date ❤️

Started as a fabric study, but Jon was serving so hard I decided to finish it up as a Valentines themed thing. They're just too cute.

#themagnusarchives #jmart #jonmartin

[Martin spins around at the sound of his name to find Jon, both visibly nervous and Jon can't stand still. In the background, Basira and Melanie are discussing options for lunch and about to leave] Jon: Martin? Do you have a moment? Martin: S-Sure! What's, erm – what's on your mind? J: I need to speak with you. Privately. That is, if you're. Erm... M: No, no. 1-I mean, yeah! Of course. Whatever you need. [Conversation in background] Melanie: Canteen? Basira: Hm, maybe. Got a sudden craving for fresh naan. Mel: There's a new spot a few blocks from here. Bas: That place has been packed since it opened. Might take a while to get a table. Mel: Eh, we've earned a long lunch. Doubt anyone will even notice we're gone. [The door to Jon's office opens and shuts before a loud thud hits the wood, and muffled sounds inside.] [Inside Jon's office, Martin has Jon held up against the door as they snog. He is noticably far less shy than he appeared in the office] M: You're being too noisy, Jon. Thought you said you wanted privacy? S'not like you to be so impatient. What's got you so worked up? J: Y-you know damn well what's- Gasp – Dear, please, this -This thing is going to drive me mad… M: Okay, can you if we're alone down here? J: [Beholding eyes scan the area] We-we are they've all gone to gone to lunch. M: Thank you love. Now, pop off your trousers for me.

A short Web!Martin comic for y'all 💜 time for Jon to live out his monsterfucker dreams too.

two panel comic: image 1: Closeup of Jon laid on his back with icing and candles on his stomach, and more icing on his cock, his body twitching while Martin licks up a stripe from the base of his cock. image 2: Martin looks up at a love-struck Jon, licking away some of the icing that's left on his lips. "You're gonna make a mess if you keep squirming, love."

Just wanted to give a quick thank you to my followers after we hit 1k yesterday! that's like. so many people. my god.

I'm working on another short comic atm, but wanted to make something special for the occasion 🎂 love y'all

I made myself a doodle to celebrate the anniversary of my Cryptid Watch au. #Jmart #donotarchive #jonsims #martinblackwood

I've Seen a bunch of Designs for Monster Jon on Tumblr and it spoke to my "Making Horrors Out of my Favorite Guys" Side

So I tried my hands on one :3

#Tma #TheMagnusArchives #JonathanSims #MartinBlackwood #Jmart

Image 1: Closeup of Jon's ass with a vibrating plug buzzing inside him. Strands of web wrapped around his cock. Image 2: Full body view of Jon hanging upside down and wrapped up in web with his arms bound behind his back. A thread is wrapped around his cock, preventing him from coming when he's not allowed. Jon is moaning openly, clearly having a good time but his whole body is trembling from however long he's been denied his release (and probably from being hung upside down tbh) Web!Martin: (lil chibi view of his face, smiling big with a set of fangs) How are you feeling, love? Having fun with your new toy? J: Ma~ Martin, please... M: Use your words, Jon. Tell me what you need. J: I-I need to come...Please, dear. Let – L-let me come, please...! M: Good boy 💜

Wanted to change it up a bit so started playing with some Web!Martin thoughts. Been making a lot of subby Martin content lately, so it felt like it was Jon's turn to get bullied (lovingly)

He's in his happy place 💜

Sleepy jon <3 #tma #jonmartin #jmart

screenshot from ao3 with fic summary: He doesn't know if he would have noticed the cold if it weren't for the bright core of heat that has settled in his lap. The contrast is sharp; a razor's edge slicing into the delicate shroud of sleep, but not enough to rouse him completely. Only enough to offer a glimpse of the waking world through heavy eyelids before the visions disappear into the dark. It all comes to him in pieces; a glint of ivory, a flash of iridescence, pitch-dark waves that bounce on slender shoulders – the mind is a wondrous thing, spinning up such a lovely scene to entertain him in his fitless sleep. It's a dream he's had so many times, one that he'll never tire of, even if the shape of it has warped with time. “Shh, don't – ahh – don't move, dear. Just – just let me…”

Shaking a bottle of melatonin to bring all the somno girlies into my yard, come get your food!

#dragonau #donotarchive #jmart #nsfwfic #themagnusarchives

Image 1: Martin is on his knees in front of the bed with Jon sat at the edge with their legs resting over his shoulders. Jon's dick looks human, still disguised behind their glamour, resting against Martin's chin. It's small and very cute. M: You know you don't need to keep this glamoured, right? (Quietly) I know what your real cock looks like, now. You don't gotta hide it anymore. J: A-are you sure it won't be too much for you? M: Not at all. I want as much of you as you'll grant me, love. J: Right, then, erm - I need a moment to... Image 2: Same pose, except Jon has let their glamour drop a bit more and their actual dragon dick is out. It's significantly larger and quite heavy, resting across Martin's face, dripping with slick fluid as it is freshly emerged from Jon's slit. Martin looks to be stunned to see it up close like this and unsure of the change in size, but his own eager twitching of his makes it clear he's more excited than scared. J: Is-is this alright, dear? (Quietly) You're staring... M: Oh Gods...❤️

Fun fact: Jon's dick when fully glamoured scales proportionally to their smaller form, so they are still considered small for a dragon even at their full size

To a human, however...Martin is gonna get much more of a jaw workout than he expected.

Image 1: A shadowy version of Jon kisses Martin hard, blood dripping from their chin. J: That's-that's it. Harder. more...! M: Jon…Stop, please we-we can't- Mmph! Image 2: Closeup of Jon's ass as they ride Martin's cock. Martin's hands squeeze their ass hard. J: Don't pretend you haven't wanted this, Sir Blackwood. Not when you're fucking me like a whimpering dog. M: Fuck, I-I'm sorry...I can't stop. Too good, it's- Gods, forgive me Image 3: Claws scratch across a white panel, drawing lines of bright red blood. Image 4: The dark vision of Jon cradles Martin's face, smiling bright while blood trickles from their chin. Martin's back is cut up to hell, but he's eagerly fucking Jon regardless. J: You're getting close. You want to come inside me, don't you? M: Yes! Please. Jon please...! J: And what will you offer me in return? M: Everything. I'll give you everything, love...Everything...! Image 5: Jon leans in to Martin's throat, their fangs puncturing the skin. Martin lets out a sharp cry. J: Good boy. Then I'll be sure to savour every last drop. M: Gasp– Oh, fuck...J-Jon...! Image 6: Beneath the fantasy sequence above is a view of Martin sprawled out on a bed with their trousers shoved down and their shirt lifted up, masturbating to his own lewd fantasy of his crush eating him alive. M: (internally) Gods, there's something actually wrong with me…

CW For blood/injury

Some pre-relationship pining. Martin can't stop thinking about his crush (tearing him apart with their claws and fangs). That's...probably normal, right?

Somewhere else
#jmart #jonmartin #tma #themagnusarchives

I have certain feelings about the tape recorders seeking Martin out. I always loved the idea that they were a completely separate entity from the eye and that little comment from Anabelle about not knowing what's truly listening in Mag 200 really sold it for me #themagnusarchives #jmart #tma

A tumblr post written by user misscryptidart, which reads: My knight: "I am a steward blade. I am a vessel of violence and duty. There is no man, beast, or devil I fear." In the accompanying drawing, Sir Martin Blackwood is staring off heroicly to one side, undercut by an arrow that points to him and reads "trying too hard to look cool"

The original post continues with: Me, lifting my hand gently: "Okay but what if I cradle you softely?" Jon lifts a hand to cup Martin's cheek with a shy smile, and an arrow pointing at them which reads: trying too hard to be suave

... Drawing of the two stood in silence as Jon keeps their hand on Martin's cheek, a soft blush on both of their faces

The final line of the post reads: My knight, suddenly shaking: "That isn't- I'm n-not, hang on jsut a second." Martin spins around quickly, clearly in a panic with one hand over their face and another gripping at his chest. He is visibly shaking, while thinking to himself: "don't read into it" over and over Jon watches with concern, asking quietly "did I say something odd??"

They're so stupid ❤️
