Dreams, man. Don't you think?

Gaster was looking at Sans who was acting different the morning...Guilty. He raised a bone-brow as he almost yelped when Frisk poked him to ask if he was ok. He stammering and stuttering like he had some huge crush and he never talked to her even once. Gaster frowned as he sipped his coffee. 

"Sans...? SANS!! DUDE!! WHERE THE HELL IS THAT SKULL OF YOURS??" Frisk said as she crossed her arms across her chest. Sans almost fell out of his chair. 

"w-what...? o-oh, i-i'm just distracted...heh..." His eyes then looked at her chest and trailed down. He quickly looked away. Gaster frowned even more. What the hell could have possibly happened. 

"Are you seriously hard at the breakfast table...??" Frisk said raising an eye-brow at him in confusion. Gaster spurted his coffee as Sans choked. OK SOMETHING WAS CLEARLY WRONG HERE!


Gaster waited as the kids were technically to sleep. What he found interesting is that that day Sans wasn't sleeping with Frisk. That's why he decided it was the best time to use the prototype for an interesting project. A machine able to see dreams. He could connect it to anyone sleeping in the perimeter of his house. He smirked as he opened the screens and looked through the dreams he could look. He decided to go from the best dreams to the worse. He started off with Papyrus. Papyrus dreams seemed interesting. He was fighting like a true soldier in the Royal Guard and cooking like a true chef. It was clear he watched Frisk cook a lot since he was doing the same movements as her. He was surrounded by admirers and he was like a super star, getting out a limousine and all that stuff. However, he frowned when he saw him blushing at Mettaton who was complimenting him. He will need to talk about that with him. next dream he picked Frisks. 

it was necessary a nightmare but it was clearly unpleasant. She was back at the orphanage, it was raining, she had her fists up, blood was running down her nose and her fists were bloody too. It was a fight with some really buff kids, it seemed unfair. 

"Look at this bitch, still fighting. Who are you fighting for, huh?" Frisk snarled and spat down as she turned around to leave. 

"Awww~ Little baby is going to cry and her dumb monster daddy can't help her~" Frisk froze dead in her tracks and Gaster was sure his blood would've ran cold. They were talking about him. She wiped the blood from her nose and sniffed. 

"Could you repeat that...? Hoe?" Frisk asked turning around with a dangerous red glim in her eyes. Luka stepped forward. 

"F-frisk--" She raised her hand. The boys backed away. 

"I said. Repeat that. Hoe." Frisk said cracking her knuckles. 

"I-I...I umm...I said..." Frisk frowned and snarled. 

"Ain't got the guts to say it to my face, scumbag??" She scoffed and chuckled. 

"I am ok with taking insults...But insulting GASTER??" Frisk asked amused. 

"You. Fucked. Up." She said. The boys stepped back again with buckling knees. Gaster smirked a proud feeling coming over him as he watched Frisk scare them, nonetheless taking a beating for him. Frisk lounged at them and Gaster's sockets widened at the speed she was going. She took the guy who talked shit about him down in a matter of second. The other boys backed away. One ran. Frisk blinked in surprise. 

"Where the hell do YOU think you're going fucker?!" She snarled as she somehow ended up in front of him and kicked him back so hard he almost flew back the whole way to the others. Frisk was a machine. She managed to take the other boys down and satisfiedly clapped her hands together, getting rid of the dirt and blood. She wiped her mouth with her thumb and Luka came to her side. Gaster was satisfied with that he saw and decided to move on onto the next dream. Oh boyyyy was he in for a treat. (breaking the fourth wall here but: bro i can't even EXPLAIN how weird it feels to write this, i've been laughing my ass off the whole time!! loved it:10/10. i'm praying to god to forgive my sins.)

Sans was in Frisk's room, chilling with Frisk...When she says she needs to change in her pajamas. Gaster raised a bone-brow in confusion at the screen. That is until Frisk came out the bathroom. He spurted and choked on the air as he saw the see through cyan nightgown. OH HELL NO- He blinked in surprise a few times then leaned back. He frowned then leaned forward towards the screen again as that Frisk was making her way, SEDUCTIVELY towards his son. Ok nope nope nope- Gaster turned around and looked up at the ceiling, praying. Then he remembered that was HIS BABY GIRL. He turned around again and frowned even more. However he also had a question. When did Frisk have a growth spurt...? And how did his son know what underwear she had. Gaster was the one that was going shopping for this kind of stuff with her. So how did Sans- That when his sockets went blank as he realized what a snooper his son was. Yeah...he's locking Frisk's drawers. Gaster watched in disbelief as his son was dreaming of Frisk sitting on his lap dressed like- WHATEVER THAT WAS. He turned around and got up from next to the machine. HE NEEDED A COFFEE. However as he was getting a coffee he didn't expect the dream to get worse. Oh but it did. 

As Gaster walked back in the room he dropped the mug as he froze dead in his place. There was Frisk...WITH BOTH HER HANDS AND FEET ON EACH OF THE BED POSTS. He turned around and decided that he was getting something for Frisk tomorrow. Of course curiosity got the better of him and he came back, frowning as he sat down, his hands together, his leg bouncing in anger and annoyance at the stuff his son was dreaming. But he needed to know how bad it was getting. Sans apparently was the tease in the relationship and he had the moves. His father would have been proud for the way he was sliding his hands under her nightgown. IF IT WASN'T FUCKING FRISK THERE! Gaster face-palmed and was pretty sure if he had any veins, one would pop at this point. He let his hand slide down when he heard a weird sound coming from Frisk and he immediately pulled the plug. He just imagined Frisk MOAN?!  As he started rebooting the system he was growing more and more annoyed. But it explained by his son had a boner in the middle of breakfast. And then he realized it was mostly because of the soul bond...Because human biology decided to include HORMONES. Oh god. 

The system started and now Frisk wasn't tied up anymore for some god knows what reason. Sans was sitting against the wall, Frisk on his lap as she was trailing her fingers down his spine. She was also grinding down on him. Gaster felt disgusted as he narrowed his sockets at the screen. His respect for his son dropped...And he was pretty sure he will be a tiny bit awkward when he faced Frisk tomorrow. But he continued watching....Well as much as he could until Frisk started sliding HER hands under HIS shirt as they were making out. He also HATED the sounds coming from them. Yeah, he needed to puke. He closed the machine and started walking. He opened his phone. 

"Hey, Siri. Where can i buy a chastity belt?" He didn't even wait as he saw he could get one in Ebbot. Wasn't Siri an angel? He also decided to take a stop and wash his eyes with holy water. 


"WHAT THE FUCK GASTER?!" Was the high pitched scream that woke Sans up from his slumber. He blinked in surprise as he woke then recalled the events from his dream. He took his pillow and covered his face with it. Fuck- But he was sure it would have felt good- WAIT NO! WHAT THE HELL WAS HE THINKING?! Get your head out of the gutter, Sans! You're both only 15! Maybe in three years-- NO! 

He slapped himself to get his thoughts right and looked down and groaned again. Yeah, no he wasn't getting out of bed now-- 

"WHAT THE HELL?! I'M NOT PUTTING A CHASTITY BELT ON!!" Sans sockets opened at the speed of light. A what now?? He teleported downstairs. 

"YOUNG LADY, YOU NEED TO WEAR THIS UNTIL YOU ARE 18!!" Frisk was looking at Gaster in disbelief. 

"ARE YOU LISTENING TO YOURSELF? A CHASTITY BELT?? WHY??" Gaster pointed at Sans in the door. Both teens looked confused at each other. 

"Him?"

"me?" They both said as they pointed at him as well. 

"YES YOU, YOU PERVERT!! WHAT THE HELL WAS WITH THAT DREAM OF YOURS!? I THOUGHT I RAISED YOU BETTER." Sans froze and he was sure he could feel his sins crawling on his back- Wait a second- 

"HOW THE HELL DO YOU KNOW WHAT I DREAMT ABOUT??" He asked frowning. Gaster stiffened as both kids were frowning at him. 

"Well...I have a machine, it's a prototype..." Sans face-palmed. 

"so you decided to take the risk to fry our brains in the process...also...HOLD ON A SECOND WHY THE HELL WERE YOU WATCHING THAT?! THAT'S GROSS!!" Sans said as he felt his privacy has been invaded. He was practically glowing because of how blue he was. 

"YOU'RE GROSS FOR THINKING OF THAT!! I ALMOST PUKED!!" Sans face-palmed.

"So you brought a chastity belt because of a dream?! Where the hell did you even find one of these?!" Frisk asked. Gaster shrugged.

"You'd be surprised to know how helpful Siri is with directions." Both Frisk and Sans scrunched their noses up thinking of what weird ass shop he must have went in for this. 

"Yeah, i'm still not wearing that...Also...What was that dream about that it was SO BAD??" Sans stiffened. He turned on his heel and walked away. 

"OH NO, YOU AREN'T LEAVING YET YOUNG MAN!" Sans waved and teleported in his room. He DIDN'T want to have that talk. But unfortunately Gaster had other plans. Sans and Frisk were both sitting at the table, flushing as Gaster was angirly glaring at Sans. Frisk frowned. 

"To be honest...? The nightgown would have probably been lilac." Sans spurted as Gaster's mouth dropped. Frisk got up, still flushing, but waved at them as she picked a plate of beacon and eggs and made her way to the living-room. Gaster pointed at Sans. 

"Y O U." Sans gulped. He was in trouble.
