Huh. I thought I would have said fuck a little more than that.

Also this doesn't come off anywhere near as horny as I thought it would, and idk whether that's a good thing or not.
A wordcloud with a bunch of words, the top 5 being: Jmart Donotarchive Dragonau Jon Martin Also apparently I say "just" a lot.

Some close-ups for easier reading (and in case the quality drops in the full pic)
Jon is chained to the headboard with their legs held apart with a spreader bar. Martin's hands are holding the bar up to lift their legs while fingering their slit. A bit of cum is leaking out of Jon's ass, but they don't look satiated yet. J: P-please... I need... M: Still need to recover from the last one, love. So just let me focus on you for a while, yeah? J: (Whine) It's-it's coming out...Feel so empty...Help me... Dear, please M: Shhh, I know, Jon. I know, it's gonna be okay. Be patient for me. I'll fill you up again soon.... Skips ahead in time and Martin has Jon by one horn in this chained up repose, holding them in place as he thrusts into their mouth. Jon is a mess, covered in sweat, slick, and their own come while their cock is already back to full attention. M: Fuck....H-how are you so good? Gods, you take me so well...Are you ready for another, Jon? J: (muffled) [h-hurry...hurry...!] Skips again and Jon is laid on their stomach, yanking on their chains while Martin fucks them hard from behind, holding them by both of their horns. Jon is moaning so very loud, their claws ripping into the bed sheets as Martin finally comes inside of them again. M: J-Jon...Oh, shit, you're-squeezing me so...Ahhh- C-coming I'm...! Smaller doodle of Martin boneless on the bed, covered in sweat and absolutely drained. J: (off screen) Mart—in, heeeelp 😭 M: (arrow pointing to his head says "ran out of cum two rounds ago") nngh...just – j-just give me a sec to...to catch my breath.

More mating season struggles ❤️

Knights tend to prioritize capturing enemies, so Martin has a variety of restraints on hand for when mating season starts. Keeps Jon from hurting themself, and his skin from being torn to shreds. Can't save the linens though.

Martin gets to have a turn with the Beholding...kinda. Just swap out the Eldritch horror for corporate horror, anyway. It's not that different, really.

#donotarchive #jmart #themagnusarchives #nsfw
Panel 1: Scene is set in Jon and Martin's bedroom. Jon is laid on his stomach on the bed, panting quietly. A phone beeps as Jon answers. Jon: H-Hi, dear, how was your flight? Martin [on phone]: You enjoying your alone time, love? J: I'm not sure what you- M: Don't stop now, it was just getting good. And you look so cute with your little toy.... Panel 2: Jon has one arm around his back, thrusting a green dildo into himself. In the background, a small personal home security cam is pointed towards the bed. J: (quietly) Oh christ, the- (out loud) How-how long have you been watching? M: Long enough to know you still haven't come. So keep going, love. Panel 3: Jon does as he's told, fucking himself on his toy for the camera, clutching the pillow behind his head with the phone laid by his side. J: Ahhh-martin... M: I hope I'm not interrupting, I was worried you might already be in bed, so I checked the cams before I called. Guess I got lucky... J: Are..Are you also... M: I am. Does that make you excited, Jon? You must be for how much your shaking right now. You always did like being watched... Panel 4: Cuts to hotel room. Martin's pants are gone and his shirt is pushed up over his stomach. He holds the phone in one hand to watch Jon while stroking himself with the other. Jon [on phone]: Mart-in... Martin: Y'know, I was wondering why you kept asking what time I'd be back at the hotel. I'm starting to think you wanted to be caught... J: N-no... M: Liar...God, your noises are driving me crazy, love. I already miss you so much. J: You-too, I miss...Dear, I'm... I'm nearly...! M: That's it... Just like that. Let me see you. Panel 5: Jon thrusts the toy in one last time and comes hard (and loud), his cock laid across the sheets spilling over and leaving a white mess across the linens. J: Ohh. Fuck-f-fuck...aaah! Panel 6: Martin squeezes his cock as he comes just behind Jon, unfortunately his hands are too full to catch the spill. Fuck, J-Jon....! Single image of Martin stood beside the bed with a rag, cleaning up the duvet that he's made a real mess of, still only wearing his shirt and looking very bashful. He has the phone propped on one shoulder as he talks to Jon. Martin: (quietly) Shit, what a mess. I can't let housekeeping see this.... (Out loud) So, erm, what are your plans for tonight, love? Jon [on phone]: Si-gh, Laundry, most likely. I ah - need to toss the linens in the wash... M: Heh, y-yeah. Same. I'm glad I got to see you tonight. I miss you. J: I miss you too, dear. (Interrupted by cat meow) Oh, and Captain. He misses you too. (Quietly) Or wait, have I fed the cats yet? M: If, erm...If you're not busy tomorrow night, maybe we could do this again? J: Hm...Depends, Will I get to see you next time? M: Oh, er, yeah, sure but...I get kinda camera shy? J: You get used to it 💚

Ascending from the dragon smut mines to bring y'all a lil wip crop ❤️

Hardest part is over but there's quite a bit to go. If I die down there when the work is through, send your comments to my next of kin.

They'll be...confused, probably.

Her name is Lulu (after the character from FFX). My fluffy lil monster ❤️
Picture of my cat, Lulu with her tongue sticking out. She looks like she's floating, but she's perched on a box that you can't see past all her fur. Another picture of Lulu sunbathing. Her fur looks more like chocolate in the sun

Made another quick Halloween doodle based on an ask on Tumblr. Lucid Jmart dressing up as their Dragon AU counterparts ❤️ still cuties

#themagnusarchives #jmart #dragonau
A more canonical rendition of Jonathan Sims and Martin Blackwood, dressed in Halloween costumes of their Dragon AU counterparts. Jon has fake horns on a headband and a plush tail stitched onto a set of robes, with a pair of leggings and sleeves patterned with dragon scales underneath. Martin looks very close to his counterpart with a tunic, cloak, and boots. But his hair is shorter and more curly and his sword is made of rounded off plastic. Jon is inspecting his costume while Martin fusses with Jon's hair, freeing some strands that aren't laying flat with the headband in the way. Dialogue: J: Hm. I think the tail is too high? Anatomically, I mean. M: I don't think anyone's gonna notice, love.

Happy Halloween!

I drew my Lucid boys getting ready for their first Halloween party (assuming they can even make it out the front door).

They're so in love and it sickens me /aff

#themagnusarchives #jmart
Drawing of Jon and Martin standing together in their Halloween costumes, dressed as Morticia and Gomez Addams respectively. Jon is leaning into Martin's side with his cane still somewhat visible behind him. Martin is holding Jon's hand, although it's unclear how respectfully he's studying Jon's dress. Dialogue: M: Oh, w-wow... J: It's not too much? M: It's gorgeous, Jon. Makes me really glad I didn't gouge my eyes out when you asked me... J: Hm. I still think it would have been romantic. M: Heh...maybe next time, then. They're standing side by side with Martin taking one of Jon's arms and kissing his hand, in a similar pose to how Gomez will kiss Morticia up the length of her arm. Dialogue: J: Ready to go, dear? M: mmm, just give me a minute? I wanna appreciate this a bit longer. J: You're ridiculous. I've worn dresses before, it's nothing special. M: Are you kidding? You look beautiful, Jon. I'll have to be careful tonight. Someone might try to snatch you up. J: (chuckles) Are you planning on eating me before anyone can try, mon cher? (Quietly: you're going to shudge your mustache...) M: Hm. now that you mention it... Martin takes Jon up into his arms, leaving more kisses along his neck and shoulders until he's ticklish. Dialogue: J: Marti-n~ were going to be late (again) M: Yeah, but we can be a little late, can't we? Those monsters are gonna eat you alive, cara mia. At least let me have a taste first... (Arrow pointing to Martin says "getting way into character") J: you're s-such an arse... (Arrow pointing to Jon says "It's working")

Jon decides to give Martin a little endurance training.

It's going...well, it's – it's certainly going.

#dragonau #donotarchive #themagnusarchives #jmart
Text at top: 30 minutes into cockwarming... Jon is sat in Martin's lap at the edge of a bed, keeping his cock warm inside their ass but not moving beyond that. They have an arm around Martin's shoulder, teasing his hair with their claws, their tail wrapped around his leg. They're clearly having a lot of fun and aren't in any rush, but Martin is sweating and looks to be holding himself back. Dialogue: Jon: I can feel you twitching so much inside. Do you need something, dear? Martin: jon...f-fuck, please...can, can I...? Jon: Had enough, already? A knight should really have more patience than this. You want to be good for me, dont you? Martin's composure has completely broken. His arms are wrapped around Jon's torso in a desperate hug, dragging them down into his lap and fucking them hard and fast while apologizing profusely for being too weak to stop himself. Jon comes immediately from this, clearly startled by the sudden force, but looks pleased with the results of their teasing. Dialogue: Martin: s-sorry! I'm sorry, I can't stop...Your arse feels so good, love, I can't...Oh Jon, I'm – I'm coming!

I hit my 2 year writing anniversary! I decided to draw a scene from my first fic, It's Too Cold, to celebrate 🎉

It's been 2 years and I am still deeply unwell about these two 💙💚

#donotarchive #jmart #themagnusarchives
A drawing of Jon laid back on his desk while wearing an oversized jumper (Martin's) that's been shoved up out of the way to expose his nude lower half. He's moaning openly as Martin fucks him, perched up on one elbow while tugging on his t-shirt to pull him closer. In the background, a tape recorder has turned itself on, silently whirring in the background. Papers and files are strewn about with little regard as to whether they don't get messy from the encounter. Same as previous image, only with onomatopoeia and action lines removed

Made a lil birthday present for @teamoth11.bsky.social of their Cryptid AU boys ❤️ I don't think they're gonna find any cryptids this way, though

Moth has a lot of writing up for these two and an ongoing longfic here! archiveofourown.org/series/4729519

#donotarchive #themagnusarchives #jmart
Drawing: Close-up of a camera's preview screen that is currently recording in a night vision mode. The scene is somewhere in the woods at night. In the frame, Jon is spread across Martin's lap, wearing only a hoodie – exposing the bottom of his soft tummy and tdick in full view of the camera – while Martin's shorts are shoved down. Jon is bouncing on Martin's cock, completely lost in the moment with his glasses nearly about to fall off of his face. They're having a great time, but they are probably going to regret doing this on the ground when they're done.

Close ups of each, in case Bluesky shits on the quality
Martin is comforting a deeply stressed Jon while holding a file, letting him squeeze his chest through his tshirt and bury his face into his tits. Dialogue: Martin: You having a rough day, love? Jon nods Martin: Anything I can do to help? The couple are hiding in a storage closet. Martin is on his knees with no shirt on. Jon is grinding against his chest while holding onto a shelf, having to get on his tip toes (and a book) to be tall enough to fuck his boyfriend's tits. Dialogue: Martin: Does this feel good, love? Jon: yes... Martin, I-I'm so... Martin: so cute. Is this all it takes to get you worked up? Jon comes on Martin's chest. It seems to have surprised Martin that Jon would come from such little stimulation, but he's not upset about it. Dialogue: Martin: oops... (Thinking) Damn. I was gonna have him finish in my mouth...so hot, tho... Martin hides behind the door, startled by the appearance of their coworker Melanie just outside. His chest is covered in cum and he has nothing to clean himself with. Jon is talking to Melanie while hiding a box of tissues behind his back. Dialogue: Jon: Oh, ah-h-hello, Melanie! Melanie: ...You're too happy. It's weird. Martin: (Thinking) Don't look in here (x3) I look like such a whore rn. pleaaase dont look in here

Some dragon AU exhibitionism to go with the last side fic I posted!

Jon continues to prove they have no self preservation and Martin is a bit extra possessive. My favorite combo ❤️

#dragonau #donotarchive #jmart
Dragon!Jon is sat in Martin's lap as he's reclined over a chaise sofa. Martin has their tail lifted to give a proper view to their ass for what is implied to be a group of spectators out of frame with looming shadows of humans and dragons cast across the wall. Martin has his pants shoved down enough to take his cock out, which rests against the curve of Jon's ass. Jon has a hand clasped over their mouth to hide their gasp, clutching to Martin's shirt. Dialogue: Martin: Are you feeling shy, love?

So I made them horny.

Works great, highly recommend
