Sorry About That (Gaster!Sans x Reader)

Man's Best Friend

When G woke up that morning, you weren't there. You had started work again, and left early so you could fetch another job. You were getting antsy, you said. You needed something to do, a distraction. He didn't know what you were possibly distracting yourself from, but you needed it so you did it.

While he wouldn't have a problem with this usually, it was a different story now. Having two males in the house and a female got... competitive? No, G wasn't going to fight with a dog over you, but the dog was really trying.

So all in all, the dog didn't like him. And being home alone with him was making G stress.

At first he opted to go to work early. So he did, with the dog loudly barking and scratching in protest. If only to save his doors and his wallet, G went back inside to wait for the normal time.

"hey, baba," The dog snarled. "or not... you want food or something? anything?" The dog perked up before G interupted. "that's not me?" The dog pouted.

Wonderful.

"Baba, baba, who's a good boy? You are! My handsome big guy, that's what you are!" You were cuddling with the big bernese again, cooing and petting him excitedly on the couch. One of the things G had to add on to his list was the shedding. The horrid, horrid, shedding that now made his laundry trips go up thrice more than usual. You petting him constantly didn't help at all.

"G! Come cuddle with usssss," You whined at him as G went into the kitchen. He looked through the fridge, and sadly, it was full. That excuse was gone until next week. G looked around, until he saw the garbage can that was tipped over, making a mess on the floor. He groaned.

"sweetheart, you need to train your dog. i'm getting tired over here." As G picked up the mess, something soft hit his head. It was your shirt. "just... why?"

"Shut up, I didn't have anything else to throw!" You yelled back, now topless. "And Baba is your dog, too! Why don't you like him?"

"it's not that i don't like him, hon," G placed the trash can back on the floor and walked over to you. Baba started to growl, so he stopped. "the dog doesn't like me."

You seemed puzzled by the dog's behavior, like you had never noticed it before. Could G give you a crown for being Ruler of Obliviousness? Alright, that was mean, but really. "Baba, why don't you like G?" Baba didn't answer, just went back under your arm.

"he's getting competitive, doll. two males, one female. he's responding like any other." G leaned on the back of the couch, folding his arms. You stayed silent, obviously upset. He patted you on the head lightly.

"Then show him who's alpha." You blurted out, like it was the most obvious thing ever. G raised a brow. "I don't know, piss on the carpet or something."

"i'm not doing that. i can't do that."

"Do you have a penis?"

"we're getting way off topic."

"Well," you tried to think. "Get your scent all over me, then." Again, like it was the most obvious thing ever. G slapped his hands on his face, falling to his knees on the floor. He laid his head and torso down on the back of it, mumbling.

"and how, do you suppose, i do that?"

"Let me wear your stuff. Oh, I actually have something that's yours, I think." You perked up, picking Baba up off of you. G's eyes followed you curiously as you paced over to your room. "It's in here somewhere. I've never seen you wear it, though. Alphys got all weird when she saw me wearing it," You shouted out.

"you saw alphys?"

"...yyyeah.." Your voice wavered. "When I got you that joke book from the bookstore. Undyne was there too, but she didn't do anything. Literally. Must have been something you said." Your voice got overly suspicious and G cringed. Not a few seconds later you came out with a big, bulky blue jacket. G's eyes widened.
