Underfell Sans x Underswap Sans

"Hiya!!"

Sans sat on the floor, staring at the television screen with utter boredom. He was bored. Like, BORED. He let his mind wander off to a more entertaining train of thought. Strangely, his mind went to a part that he never thought would have occurred in his head: that Underswap him. Last month, some undertale kid went and destroyed a second barrier, and now all these alternate versions are allowed to wander into other universes. He met the strangest acting little weirdo there, this... This... Hyper little .. Marshmallow. The 'marshmallow' being an alternate him. And fuck, he was cute. He took a liking to his brother. He wasn't so uptight and ready to beat the determination out of you. "Shit... " he mumbled as he caught himself wanting to hug him. There was three knocks on the door, each lazier than the last. "FUUUUUuuuuuccck......" He groaned as he got up to get the door open. It opened up to one of the lazier of the Underswap bros. "Oh. Okay. What?" He said with slight excitement that he was here. "Hey uhh.. My bro... He's uhh, stopped back there, getting somethings for a 'friend', hard to tell who, cause he has a million... But he wanted to come visit to see you, and told me to keep walking. He may be a while." He said in a rather slow tone. Sans nodded with a slight smile to hear the enthusiastic ball of dorkiness is here too. But then it occurred... They were in HIS universe. Monsters would kill for LOVE, or extra HP. No matter who it be. "HOLY SHIT!! YOU JUST LET HIM WANDER OFF IN A WORLD FULL OF MURDERERS!?!? YOU DUMBASS!" He screamed as he bolted off near the ruins, hoping Toriel found him. Halfway there, he ran into someone he hardly noticed was there due to snow blowing in his face. "Ahh... Shit... My fuckin head..." He grumbled. He looked up to see Underswap fallen in front of him, somehow managing to look completely adorable. He bolted up the minute he noticed he may have injured someone. "OHMYGOSHAREYOUOKAYIMSOSORRYSORRYSORRYSOR- Underfell?? Oh, u-uh, are... Are you okay? You look sort of scared... I must have startled you pretty bad." He spoke, hiding something Behind his back. As soon as Underfell recovered, he glared sad but frustrated red eyes at Underswap. " You god damn idiot. Do you know how many things here could kill you!?!? Augh, Forget it. Let me get you somewhere where I'm okay with you fucking around in, you little careless fuck." He grumbled. Underswap shoved a Hershey kiss in underfell's mouth, nearly choking him to death. "LANGUAGE!!!" He screamed, completely oblivious as to how many people and monsters from this universe were staring him down. Underfell's face slightly, SLIGHTLY, BARLEY EVEN NOTICEABLY, blushed a teeeeensy bit. He grumbled and grouched as he swallowed the chocolate Hershey. When they neared underfell's house, Underfell got a tease worth smirking about. He rushed to the door first and opened it with a wink, commenting, "Ladies first." However... The wink seemed to have overdone it as Underswap was a dark blue. He mumbled quietly about how he wasn't a girl, and walked inside, careful not to let the other know what was in his hands. "I remember you like making tacos. Wanna make some?" He offered. Underswap got this huge smile plastered on his face, nodding frantically. Underfell chuckled, and Underfell made his way over to the sofa. He payed down on it, already getting comfy. He looked over at Underswap, who was probably about to cry... If that was the case, he in deep shit. He knows his brother is around somewhere... "But... But... The tacoooooos..." He whined, already beginning to tear up, with a light blue tinting his face. Underfell looked at him like was crazy, then chuckled. "Heh. Well shit. I didn't know you wanted to go make them so soon." He said, as he, pretty boldly, reached out to grad Underswap, and yank him onto the couch to cuddle with him. Underswap blushed, probably from head to ankle. "Still wanna make those fuckin tacos now...?" He teased, seeing the expression on his face. Underswap lightly tapped his mouth, in a weak attempt to shush him. " language..." He mumbled, blush still apparent, and cuddling up to Underfell sans more."And the ... 'Fucking tacos' can wait." He mumbled quieter. The bad word that just came out of the others mouth deeply surprised him, and he swore he just wanted to kiss him. Other monsters and prople in his universe would have gone to rape, but with a guy this innocent... Maybe it's better not to even kiss him... But oh fuck he really wanted to... He looked down in underswaps hand. It seems to have been carrying a small bag... But right now, he didn't care. His red eyes wandered up to underswaps eyes. Unfortunatley, they were closed, and he seemed to be asleep. Underfell leaned over just a little, and gave him one small kiss on the lips... But it just happened that it lasted longer than he thought, causing him to lose his breath. He pulled back, completely forgetful as to what he just did, and what he's thinking and feeling, and now dreaming. Every one of those was Underswap Sans. He thinks he heard someone clear their throat and a slight growl, but he didn't care. "Aww. How cute." A voice said, even sounding lazy.
