#g!bros

I chose 10 prompts from my big What If list that I’m going to try to write up this month. Feel free to send asks for G and Aster (or other characters from this AU)!

Axe

Edging/Orgasm denial. He’s always just taken what he wanted in your relationship, and you don’t mind one bit–so the first time you top he’s startled by how much he likes being denied that release. He doesn’t like to beg, so it can take hours for you guys to finish these sessions, until he’s practically in tears.

Sugar

Sensation Play/Blindfolds. He’s embarrassed by his ecto-body, because it’s so small and undernourished, but a side effect of that is that it and his bones are incredibly oversensitive. He’s too nervous to tell you what he likes, but you figure it out pretty quickly.

Black

Pegging/Domme. Yes, you read that right–your eternal Dom has a secret kink for being fucked in the ass and dominated in every way. Maybe that’s why he’s always so insistent on being on top, because he doesn’t like to be powerless…except he really does.

Mutt

Salirophilia–he gets aroused at the idea of messing up your appearance. Every time you get ready for a date, hey, you look hot as hell–but he can’t help but think about how you’ll look once he rips those clothes off, smudges that eyeliner with tears, and smears your lipstick on his dick. The idea of messing up your perfectly coiffed hair keeps him going all through dinner. He takes pictures sometimes once you fall asleep–that’s how you find out. Honestly, the only thing you feel he has to apologize for is not telling you–you proceed to get all dressed up for no good reason on your day off. Just for him.

G

Tickling. He’ll never admit it until you notice it. He thinks it’s weird, and he refuses any tickling from you until you sneak up on him one night and tickle his ribs–only for him to moan embarrassingly and then promptly lock himself in the bathroom while you try not to laugh at his embarrassment.

Green

There are a LOT of skeletons and I know I don’t always use the same nicknames as everybody else. Hopefully, this will help you keep them all straight. 

Undertale - Sans and Papyrus

The original skeleton brothers.  These are the lovable skeletons you met in the game.  Well, my interpretation of them anyway. Sans is lazy and punny and Papyrus is Great - even more now that they’ve been on the surface for a while. Sans works at the planetarium.  Papyrus is the Monster Ambassador. 

Underswap - Blue and Stretch

Sans and Papyrus if their personalities were switched. Blue is loud, energetic, optimistic, and ambitious.  Stretch is quiet, lazy, punny, and struggles to find his ambition.  (It’s around here somewhere…maybe it fell into the crack between the couch cushions?) Blue works as an instructional assistant at an elementary school during the day and a security guard at a big company in the city at night.  Stretch is technically a published author, although he hasn’t written anything in this timeline.  He did recently get back to writing, though. 

Underfell - Red and Boss

Sans and Papyrus if their world was…not exactly evil but pretty gung ho on the “kill or be killed” idea.  Red is an anxious mess masquerading as a marshmallow masquerading as a tough guy.  Boss is a noble soul hidden beneath way too many layers of bravado and grumpiness. They had a falling out a few years ago and only recently rekindled their brotherly bond. Red works as a service tech at a computer store.  Boss is the office manager for a big company. 

Swapfell - Black and Mutt

Sans and Papyrus if Underswap and Underfell had a baby. Their world was “kill or be killed” too, but their personalities are swapped.  Black is a Jane Austen hero in skeleton form who prefers to keep his issues to himself.  Mutt is an absolute sweetheart who is better with animals than with people. Black is a police detective. Mutt works at the animal shelter. 

Horrortale - Sansy and Sweets

Sans and Papyrus if they lived through the neutral run where Undyne becomes empress and everything went really, really wrong.  They did eventually get to the surface, but things got pretty dark before that happened.  Sansy escaped with a hole in his skull, memory problems, and a bit of a snarky side.  Sweets has braces to correct the problems with his teeth, glasses to help his eyesight, and the same sunny disposition as always.  Sansy works for a package delivery service.  Sweets works at Muffet’s bakery. 

Mobtale - Bones and Lucky

Sans and Papyrus if they lived in a 1920s gangster version of Undertale.  Monsters were never trapped underground in their timeline, but they were second class citizens. It’s taken them a while to adjust to this timeline, but they’re doing all right.  Bones is still a punster with a wicked grin, but he’s a bit out of his depth at times with modern stuff. Lucky is a perfect gentleman with a strong sense of justice and a love of music. Bones is an independent hot dog vendor.  Lucky is a lawyer with the Human-Monster Alliance. 

Mafiafell - Smiley and Grim

Sans and Papyrus if Underfell was a 1930s gangster version of Underfell. Their timeline was rougher than the Mobtale boys’ (just like Underfell was rougher than the UT timeline) and they were involved in some shady stuff. Smiley is a big flirt with a heart of gold.  Grim can seem really uptight and stern, but if he likes you, he’s the best guy you could ever have on your side. They both run a casino out in Vegas, but mostly work remotely nowadays. 

Gaster Brothers - G and Aster

Sans and Papyrus if they each fused with a version of Gaster.  These two aren’t technically brothers - they’re from two separate timelines - but they found each other in the Void and adopted each other.  They found a way out of the Void that involved going through several other AUs before they finally reached the Best of All Timelines. G is a monumental dork trying to act like an incorrigible flirt.  Aster is a shy nerd who just wants to make everybody happy. G doesn’t have a job yet.  Aster is a college professor.

Outertale - Comet and Captain

Sans and Papyrus from SPAAAAACE!  They followed a mysterious signal to this timeline and ended up crashing through the machine, breaking it forever.  Comet is a shy boy who loves plants.  Captain is a fearless and bold fellow with a flair for the dramatic and a love of animals. Comet is going to college to get a degree in botany.  Captain works at the animal shelter with Mutt right now, but is thinking of looking into jobs at the aquarium instead. 

Dancetale - Break and Tango

Sans and Papyrus from a universe where monsters dance instead of fighting.  Every monster has a specific dance style and type of music that is their specialty.  It comes from their soul.  They can learn other dance types if they want.  Break is generally easy-going, if a bit shy, and he doesn’t dance (anymore).  His style was hip-hop/break dancing.  Tango is a dramatic and flirtatious fellow who loves to dance and will encourage anyone to join him.  (You can guess what kind of dance he’s best at.) These two have been in this timeline for years now but they went on tour with a dance troupe (well, Tango danced and Break was there for moral support) and only recently rejoined the group. 

Underocean - Bubbles and Finn

Sure you can!

G

He knows all about your relationship’s shortcomings–you’re loose-lipped when you drink, and you’ve told him about the screaming, the arguing, your fiance’s jealousy of your friendship. So when you show up, he isn’t surprised, expecting another vent session and then everything to return to normal–but this time you have bags. And a bruise. That fucker actually fucking hit you! G can’t stand idly by anymore–being unhappy was your choice, but he won’t let you stay in a relationship with someone who would raise their hand to you like that. He won’t let you be abused.

He brings you inside and tells you exactly that–he’s done waiting around, letting you make that same mistake again and again. He wants you to stay, and it’s an argument at first because you think he’s implying you can’t take care of yourself, but in the end you break down sobbing because it’s all you want, to stay with him, to be with him, and you’ve been pretending all this time, because you thought you had to, and it hurt so much, and he holds you until the shaking subsides.

He goes to get the rest of your stuff while Green distracts you with dinner and a movie of your choice on Netflix. Your ex texts you a bitter apology, calling you a coward for sending your “heathen boyfriend” to get your stuff, and it hurts…but when G returns with a scuff-like bruise on his cheekbone and a smile on his face, you aren’t so concerned about your ex anymore. He’s probably just bitter because G kicked the snot out of him, which you say, making G laugh as he pours you each a shot with a wink.

Green

Green’s only concern is you, right off the bat. He ushers you into the house, taking your things, and before you know it he’s fixed you a cup of tea and healed your cheek, a genuine look of worry on his skull. As you speak, he listens intently, your hands gathered in his comfortingly. The verbal abuse, the anger, the jealousy…he’s trying not to be clinical about it.

He offers you the guest room immediately, of course, and tells you you are welcome to stay as long as you need, and as he helps you settle, he’s thinking of how he can get the rest of your things for you, but you’re thinking that something is missing here. When he says good night, he pulls you in for a hug, and it’s gentle and cleansing and there, that right there, that’s what was missing.

You regretfully let him go and say good night, and you’re pacing the room an hour later when you get a call from your ex. Against your better judgement you answer, and he lays into you with a litany of colorful language, saying he knows where you are and who you’re fucking, and you’re too shocked to say anything–but the door flies open and Green comes stalking in, pajamas and all, gently taking the phone from your hand. He puts it on speaker and pulls out his own phone, recording the garbage spewing from your ex. He does that the entire time, and when your ex seems done, he plays the tape back, and says the restraining order paperwork is in the mail, and he should sign it quickly, throwing you a little wink that makes your heart stop.

[START HERE]

Green looks haggard, but happy to see you when you limp in on your crutches.

“Good evening!” He greets you, shaking your hand warmly. “Take a seat so I can look at that leg, hmm?”

He chats idly as he goes through your checkup, and you can't help but relax in his presence. He's always had that effect on you, and even Red back in the hospital room you stayed in.

He's every bit as tall and large as Papyrus and Edge, even taller, actually--he probably breaks seven feet, and he doesn't slouch and his shoulders are always squared...but he isn't anything close to intimidating, and exudes a sense of gentlemanly charm, almost as if he was built classier. It could be the way he dresses, with turtlenecks and slacks beneath his lab coat and the reading glasses sitting on his nasal ridge. He just...looks friendlier?

You find yourself noting his gentle touch, and wondering if he wouldn't mind giving you a hug. You've always liked being hugged by tall people--the way they pick you right up off your feet and squeeze you tight…

But he's your doctor, so that might not be appropriate?

[Ask him]

“Glad you asked, Angel~” G chuckles, appearing behind you. You find a sword pressed to your throat, fake of course, but it emphasizes what you could guess is a pirate costume. “Aye, lassie, ye be walkin’ th’wrong path with that fine booty, though heartily I must admit, ‘tis nice to watch you walk away.”
