im GENUINELY going to tie mumbo down loose enough so i can still feel him thrash against me but tight enough that he can't move in any meaningful way and then i am GENUINELY going to get the smallest blade i can find so my fingers can touch his skin as i cut into him and then i will GENUINELY wait until he's stopped crying and gone numb to the mild pain of surface cuts and cut him fully open and make him feel a pain he cannot comprehend and then once he's passed out from pain / blood loss / whatever i will GENUINELY fix him up regen potion style and give him a little kissy and tuck him into bed so cute . i would be privy to cuddling him also
I don't really keep up with Martyn but it does seem like he is a woman but instead of confronting that he's just doing the weirdest possible shit as a kind of sleight of hand distraction but for his own sense of self
Horny people legally cannot consent. Horniness is a clouded state like inebriation. If you are partway through sex and you realize you might've become horny, it is illegal to continue. If you have ever made someone horny, you are a bad person.

Should've put this together sooner, but that's life!! Wanted to give a MASSIVE thank you for all of your kind comments and tags! I love doing this fest and you guys always give the best prompts! Blowing you all big kisses!
As a note, I’m not including content warnings for each prompt in this masterpost, but they’ll be listed at the top of the page once you click a link!
kraken/octopus/squid scar should fuck pirate grian, like the ship comes into his territory of the sea and he attacks the ship but sees grian and spares him so he could take him to his cave or where ever he lives to fuck and try to get pregnant, he uses his hectocotylus/dick (the hectocotylus is what octopus release sperm out of, if I did my research right) and shoves it so so deep into grians cunt that he thinks he can feel it in his throat, and it’s also very very thick, and scar is so much larger than him in general
-🕷️
YESSS
Grian is so thankful to be alive. He thought he was going to die, sinking into a watery death. But then he wakes up in a cave. There's just one small issue. His clothes. They're gone. His face is red from embarrassment, but he starts to look around for the missing clothing.
He hears a sound from the water and spins around to meet Scar's eyes. Scar's eyes sparkle with excitement when he sees the human alive. Grian's face is filled with awe, temporarily forgetting about his nudity.
Scar coaxes Grian towards the water, and he does so, moving with nervous energy. Grian sits at the edge of the pool, eyes wide. Who could blame Grian. He was just a common ship boy new to the seas. That doesn't matter to Scar. He's just happy the boy is so obedient. His tentacles wrap around Grian, pinning his wrists above his head and parting his legs. Grian lets out a noise of surprise and tries to squirm free, but Scar's grip tightens. His hectocotylus finds Grian's pussy, wasting no time in shoving it inside Grian.
Grian cries, so wet but also scared. What would this beast do? Fuck him then kill him? What would happen? Did he survive just to be fucked then become dinner? Scar caresses his face with a webbed hand, kissing his face and petting his hair. That's honestly comforting to the blonde. The kraken is quite pretty, and God, he was making him feel so good. And the kraken was being so nice to him, so maybe he just was lonely.
The tentacle fills Grian's walls. It fucks into him hard, leaving Grian's eyes rolled back and having him cum multiple times. It punches into Grian's womb, and all Grian can do is beg for more. He's so needy to have his pussy filled with this creatures hot seed. He wants to be filled up with cum and be a good incubator for this creature. Scar coos at him the whole time, cherishing his little human.
(I am going to change Kraken anatomy a bit. Because humans don't make eggs like octopus do).
He preps his human, watching him cum over and over with glee. Finally, he pumps his eggs into the human's waiting womb. I'd say under 50 eggs. Maybe he puts around 15 or more inside Grian. He fills Grian's womb then pumps several loads of cum into the womb to fertilize the eggs.
When it comes time for the babies to be born it's such a slow process due to all the tiny suction cups on the tentacles on his babies.
i just read your gem birthday fic (sorry im late) and it was AMAZING. i think my favorite part was the scrabble game, somehow you made that insanely hot. i will be thinking about Grian saying cunt for a loooong time..
i was wondering do you have any tidbits to share about what happened after they left the farmhouse and stayed with oli for the week? or maybe when they got to rotterdam? they were having such a tough time saying goodbye before grian was invited along to sheffield for the week, i imagine it's even harder for them to say goodbye after rotterdam 😢
anyway congrats on the wedding!! i also love your wife's works too, you guys are awesome, rpf power couple fr.
Thank you so much! I'm really glad you enjoyed it <3 I think I still need to go through it and fix some typos, because I was rushing posting it on the day. Literally on our wedding day lol. I read this aloud to Jo and we had a little giggle at being called a power couple, so thank you for that :')
Re: Post-Rainout. I do have some thoughts, they're not super cohesive though. The main story really is just the weekend they spend together, and I'm kind of reluctant to go into the after details because we know some of the stuff that happened at TwitchCon, behind the scenes, and I don't particularly wanna write around that. THAT BEING SAID...
They probably had a really great week staying with Oli, but his house is pretty small I think? So I imagine both Grian and Gem sharing a pullout sofa together. And after a weekend of just being able to give in to urges and fuck whenever they want, it's difficult. Especially after both of them had been secretly pining for so long. They probably try to be quiet while fooling around but feel super guilty about it because they're in Oli and El's living room or office or wherever, so it never goes all the way. Maybe they get desperate & frustrated enough to sneak out to Grian's car in the night for some privacy. They're not as subtle as they think, the car is Not soundproof, and Oli definitely sees them and teases them about it for the foreseeable future. Hey guys, remember the time you banged in our driveway?
Other than that, it's just really nice to spend some time on double and triple dates with Joel and Lizzie, Oli and El. They get to feel like a real couple even though they haven't officially talked about it. Also, maybe Gem gets to see Grian with LDShadowBaby and it gives her Feelings™. And vice versa. I think seeing Gem hold a baby would make Grian slightly insane (me too buddy).
The night before they head off to Rotterdam, they drive back to Grian's house so he can grab fresh stuff for the trip. Maybe they have a nice little domestic night. Gem can do some laundry so she's also got fresh clothes for TwitchCon, Grian cooks or orders dinner, and they're both excited to spend the night alone together again, and looking forward to sharing a hotel room in Rotterdam. At that point, they finally have a serious talk about what kind of relationship they can have, long distance, what they want, what issues might come up, if it's worth the effort etc. But they already loved each other so much as friends that they decide it's worth the long distance. They do decide to play it cool in Rotterdam though, they'll be hanging with a lot of people who don't know about them yet.
Re: TwitchCon. In this timeline Grian probably doesn't go through his kidney stones issue, doesn't wear his wedding ring (he's divorced in this fic lol). It's just a sweet fun trip for them except for the Avid drama going on in the background, which they avoid getting involved in. There's a small gang of them that go to Amsterdam for a night together and I low-key imagine Jim, Kirsty, Gem, and Grian going splitsies on a space cake just to try it, and having a very stoned evening in Grian's hotel room. All of them cuddled up in bed watching TV and snacking. This is my AU and I can do what I want and I want them high af. I have more explicit thoughts about this situation but I won't get into it rn.
At this point in the trip, Gem knows she only has a couple of days left with Grian (and the rest of her friends I guess) before she has to go home. She spends as much time as possible with them, and then travels back to the UK. She's flying home out of London so she and Grian would probably stay in a hotel near the airport to maximize their time together rather than driving all the way to Grian's house and back. They're both sad that it's their last night together for real, at least for a few months. Gem talks about visiting for Grian's birthday in August, he laments that he can't wait that long. And it's his turn to visit her, anyway. Summer in Newfoundland, maybe they can finally do that fishing trip together? They start making real, concrete plans to be together.
They won't be able to kiss goodbye at the airport so they spend the night making up for it. Spoiler alert, they decide to risk it and kiss goodbye at Gem's check-in anyway. It's fine, nobody sees. But at that point they both start to realise that their relationship isn't something they want to hide for longterm. Grian had spent most of his marriage trying to keep his ex-wife out of the spotlight, and over time it had taken its toll, led to bitterness and resentment. He doesn't want to do that again. They'll keep it to themselves for a little while longer, but not forever.
At some point far in the future, Gem moves to the UK, and Grian buys some properties in NL for both business and personal reasons, and they travel back and forth fairly often (though, definitely more based in UK). They're pretty open about their relationship online, always streaming together and posting photos from their trips and vacations. I think, after his divorce, Grian thought he'd probably never want to get married again, but the longer he spends with Gem, the more he thinks about how much he actually wants to marry her. Have a family with her. And hell, she's already uprooted her whole life in Canada to come live with him. That alone is a huge commitment.
And so, one day, he proposes. And she says yes.
And they live happily ever after, because I said so. I'm gonna shut u here though. I could think about this AU forever and ever tbh, it's so cozy and domestic to me, and that's one of my favourite things in fic. Softness. I just want them to have a happy ending.
i really dont like when people draw mumbo (character) so lanky and skinny... where do they even get that from like irl mumbo isnt lanky . + have you ever seen his tits in a tighter shirt? you can't erase those
this is like also similarly why i basically never draw him in the suit . i cannot begin to imagine irl mumbo in a suit. he seems frightened by tight clothes everything i've ever seen him in is as loose as he can get away with and also almost always jeans

Very mean rpf thought I had earlier was what if one of Grian / Gems friends caught them in the act, maybe secretly recording them... then they threaten and blackmail Grian into having sex with them, etc., or else they'll leak the relationship to the internet.
They don't necessarily blackmail Gem in the same way, because they want to be #feminist or whatever, but she could find out and get involved eventually.
I just think Grian should have bad noncon blackmail sex. Forced into it by someone he trusted. That's all. Ok goodnight
I just think that Scott thinks he can unlock Grian's bisexual potential therefore it's okay to manipulate him because it's for the greater good of getting him to 'realise' his identity. I think he is enough of an ass to not even really realise how messed up what he's doing is. Because it's fine if it's a man, right? It's a win for feminism? For gay rights? Or something?
Nah, he knows he's being awful, but he keeps himself in plausible deniability. Or he thinks so. He would never harm the Real Victim in this situation (Gem) (who should obviously not be with a het man). Anyway...
I have always found it fascinating how Grian will be close and a bit flirty with most of the men in his life but not so much with Scott. Always talking about how good and nice Scott is in a very respectful way. Maybe Scott can use that against him. Ask him what's so different about him. Try to lead him down a certain train of thought. "What's wrong? Is it too real when it's with me?"
He can 'convince' Grian to 'just try' taking it up the ass. :) And feel like he's really making a difference in 'helping' Grian 'find himself' because he conveniently forgets how much blackmail material he has on G.
Scott convincing Grian that this will make him better for Gem too... Taking pics so he has more blackmail material as well as lying and saying he's sending it to Gem. Grian thinking Gem not bringing it up is a sign that she's into it. Gem not knowing the whole time. Wondering why Grian is getting more distant and weird. Sighs dreamily. Yes
Now imagine the grigem hurt/comfort of it all with me. Hold my hand and imagine Gems reaction when she finds out. Maybe first she thinks he's cheating. That the videos Scott sends her are because he found out Grian was seeing her and felt guilty. But then when she confronts him he's confused and hurt and sad ^-^ and she realises exactly what's being going on and she's horrified ❤️❤️
having to be cordial and nice in public despite everything that happened because G is so worried about everything going public and his life being basically analysed into the ground or being accused of making things up or- worst of all!- Gem being hurt in the process.
Also raising u this extra: Grian is!! bisexual but now it's gonna take him sooo much more effort to figure that out because his experience with men is 1 drunken handjob in university and then This. Erm. So.
He thinks he doesn't need to unpack it because he's with Gem and she has told him she's not leaving him over this and never would. But he probably should unpack it.
He's also kind of worried he's being homophobic 😭😭😭 like no king you got manipulated and assaulted 😔
Thinking about a world where Mumbo breaks up with Grian (for being obsessive/possessive, perhaps) and then gets with Scar a little while later. Which makes Grian mad. So one night he breaks into Mumbo’s house and rapes him and chokes him and cries about how it’s so unfair that Mumbo left him. And Mumbo feels like it’s all his fault and he doesn’t tell Scar what happened because (in his mind) he basically cheated on him! And since Mumbo is hiding it, Grian keeps doing it. Scar doesn’t find out until they’re about to have sex for the first time together and Mumbo breaks down sobbing when he’s touched :)
-Tek
oh delicious i love when grian is evil and terrible and sucks
awww poor mumby :(((( he just wants love and affection... everything gets ruined for him so fast </3 he thinks it's his fault and that he let it happen and scar will leave him if he says anything wahhh
mmmm mumbo breaking down when scar tries to touch him sexually for the first time <3 waow... he would be so cute all sad and scared and sobbing... scar would be super niceys about it tho !
ok ruins your ship. What if Grian cheated on his wife and gave up everything he had planned with her, this whole life he had mapped out, and lost the respect of his close friends because his wife tells them all about it. All because Gem implies that she wants him. Only for Gem to turn around like :/ yeah I'm not gonna get with a cheater? Do you think I have zero self respect? Ew.
aand then grian punishes himself by getting into bad unhealthy friends with benefits bsdm situations with several of his friends to try to fuck and beat the pain away lol
and maybe gem wasnt even into him she just wanted a bit of quick sex and thought he was separated from his wife already so when she found out she immediately got the ick lol
The reverse of Fie's Wife Jimmy AU where Grian has to move in with Jim and Kirsty because he divorced his wife for Gem but she doesn't want him either
🥭
ok thats kind of funny alright
grian has zero reason to move in with jim except maybe he gives up his house to his ex wife and. idk. the other properties are being used by other people? #landlord #hedeservesthis
anyways he's being all sad and whiney about it. meanwhile jim is just like dude you did this to yourself. cmon.
maybe they fuck about it. mostly grian is just needy and sad and wants someone to touch him. he would usually want to overpower and fuck jimmy into the mattress but he has no energy or willpower to do all that so he just lets jim manhandle him. all with kirsty's permission, which makes grian feel worse lol.
