A dreamy pay-back
Frisk was narrowing her eyes at Gaster. Sans raised a bone-brow at her.
"what's up?" He asks as he looks at her. She lets her eyes narrow even more.
"You realize that...Gaster has seen our dreams...but we never seen his?" Frisk asks as she looks at Sans. He smirks.
"why you say that...?" Frisk starts smirking as well.
"Well he did meet a special someone and snuck out yesterday to meet her..." Sans blinked in surprise.
"are you saying what i think you're saying?" Frisk nods.
"You in?" He chuckles.
"oh baby, i am so in!" They fist-bump and they both look at Gaster who has a bit of a dumb grin on his face. Frisk snorts.
"Now i know where you got it from." Sans gasps, pretending to be hurt.
"i will let you know i do not grin like an idiot-" Frisk leans in and kisses him. He stops with his hand lingering in the air.
"nevermind..." He says as he lets himself smile. Frisk giggles as she hugs him. Gaster pretends to gag.
"What are you? A child? Sheesh.." Frisk says looking at Gaster with narrowed eyes.
They waited for Gaster to go to sleep. They managed to put a magnet on the door and the mechanism didn't let the door get locked. Frisk and Sans smirked as they could finally hear him snore and they entered in his workshop. Frisk and Sans looked around a bit then Frisk pointed at a machine in the corner. Frisk snorted as she saw a sticky note saying 'PG +18'. She looked at the buttons and then at Sans.
"don't look at me. i never used this thing." Frisk shrugged and turned it on. She looked around the buttons and quickly got an idea how it may work. She looked at the screen and saw she could select the person they wanted to watch. Sans chuckled.
"oh this is going to be good~ hit it, baby-bones." Frisk snickered.
"One dream coming right up!" Frisk was sipping a Caprisun she stole from the kitchen and finally the dream booted. There were Kat and Gaster in Gaster's room. Frisk blinked in disbelief as Gaster was actually dreaming of this. The dream became static and now it was a lab and they were just doing an experiment together.
"No way...This fucker is trying to control his thirst!" Frisk said as she leaned forward to watch them mix some chemicals up again. Sans and Frisk both started laughing at that.
"Guess we know where YOU got it from!" Frisk said with a smirk. Sans flicked her in the head.
"yeah yeah...save the comments for later, we're still intruders, amigo." Frisk frowned.
"Oi, watch it! Don't use my own language against me!" Sans snorted and then Frisk spurted as she was watching the screen, right in Sans face.
"ew." He said as he wiped his face. Frisk pulled his sleeve and pointed at the scream. His face scrunched up in disgust. The dream had already taken a wrong turn. Kat was taking off her lab coat and in Gaster's vision it was the sluttiest thing ever.
"man he's lonely..." Frisk tilted her head.
"How in the world aren't her nipples showing through that thing material...She's totally not wearing a bra." Sans spurted.
"what the hell, frisk?!" Frisk shrugged.
"Hey, I'm a girl for a reason, ok??" Sans groaned as he glowed blue in embarrassment. Frisk added.
"If it helps, I'm not wearing one either-" Sans covered her mouth.
"you can stop now. we came here for dirt, not dirty." Frisk snorted.
"Nice one." They watched the screen to see Gaster approach Kat as he started sliding his hands under her shirt by grabbing her waist. Frisk nodded.
"He's got some moves, not going to lie. Will he pin her to the wall??"
"what's this, a james bond movie? hell no." But Sans was wrong. Right as he did the dream changed again.
"Aw man...he needs to let loose...He's just pining..." Frisk said with a pout. Sans looked at her with narrowed sockets.
"should i be concerned?" Frisk shrugged.
"No one said i'm not a pervert. I know more than i let on. Now shush, we need more dirt." Sans frowned.
"you already got a rock." She looked at him up and down and gave him an unimpressed look.
"right....15...got'cha." They turned around to see Kat walking towards Gaster, smiling, in his room. Frisk sipped her Caprisun again. Kat sat down on Gaster and was surely ready to jump those bones. Frisk spurted her juice out again, on Sans.
"at this rate you won't drink any of it...yuck...jesus learn to swallow--" Frisk and Sans both realized how wrong that sounded and started snickering. Kat and Gaster were getting ready to do the dirty. Sans backed away and turned around.
"UGH! i can't watch that shit...that's my fucking dad..." Frisk scrunched her face up in disgust as she realized they were in underwear now.
"Literally…" Frisk said. Sans turned around and pretended to gag.
"GROSS! why the hell are you still watching.
"If he will actually put his hands to untie her bra? HE'S TOTALLY having that type of dream...If it's changing, we're out." Frisk was hoping the dream would continue. The teasing could be endless.
"ugh frisk what the hell-- WOAHHHH! OKK!!!" He covered her eyes just as Gaster was the one getting rid of the last layer first. Frisk frowned.
"The hell??" She asked. Sans looked away as well.
"which button is to turn this shit off...??" Sans asked, disgusted.
"The red one, dumbass." He pushed it and sighed in relief.
"Explain...??" She asked, confused.
"dad was the first one to--" Frisk put her hands up and shuddered.
"Thanks. I'm out." Sans snorted.
"wanna follow his lead...??" Frisk looked at him, unimpressed.
"right. 15...damn it." Frisk snorted and grabbed his hand.
"I just wanna sleep...Let's go..." Sans clicked his tongue and finger-gunned her.
"coming right up." He pulled her in a hug and they teleported away.
"Had a nice sleep, Gaster?" Frisk said with a smug look as both her and Sans were sipping from their cups and looking at him. He blinked in surprise.
"Uhhh...Yes...??" He asked confused. Frisk and Sans looked at each other with a knowing look. Gaster frowned.
"OH, SPIT IT OUT ALREADY YOU RASCALS!" Frisk and Sans smirked and turned their mugs over. On them put together you could read: Boned her like a skeleton. Gatser spurted his coffee in disbelief.
"THE HELL?!" His face was bright purple. Frisk slurped loudly as Sans leaned back and put his feet on the table. Gaster growled.
"SO YOU TWO DID GO IN MY OFFICE! WHY YOU--"
"MORNING!" Papyrus said, cheerfully. Frisk panicked and almost dropped her mug. Both teens pocketed their mugs in their inventory and started laughing at the scare as Gaster was fuming with rage.
"payback's a bitch, huh?" Papyrus tilted his head.
"WHAT'S A BITCH?" Frisk frowned at Sans and smacked him over the skull. Gaster sighed.
"I hate all of you...I'm going back to bed...AND I'M MOVING THE DREAM MACHINE! You all are dangerous." Frisk snorted.
"Go get her, tiger." The two started laughing as Gaster stormed off.
