The little bone
If it's one thing Sans had learned...Is to watch out for Apollo when he tries ANYTHING with Frisk...Why? Here's a few examples.
Sans was sitting on the couch with Frisk. They were watching TV and Apollo was close by. But our skeleton decided to ignore it and concentrate on the sleepy Frisk next to him. He smirked and yawned, letting his hand linger behind her. Frisk snorted, rubbing her eyes sleepily.
"What a cheap move.." She muttered. Sans chuckled as she leaned into him and he felt her head fall heavy on his shoulder. He closed his eyes and relaxed. Apollo however? Didn't really approve. As soon as he felt it he shot up and started making his way to them. He managed to get to the couch and jumped between them. Suddenly, he grew in size. Sans was thrown off by the shift in weight and when he opened his eyes he was surprised to see Apollo being A LITERAL BARRIER between them. He was now 5 feet tall at least. Frisk groaned.
"Apolloooo...baby, please get off." Apollo whimpered. Sans watched as Frisk immediately looked up.
"Aww...You need something little baby??" Sans sockets went blank at how easily he hogged her attention. Apollo whimpered and made a small rumble. Sans frowned.
"My baby needs food?? Alright, come on, boo. Let's get you something to eat." Sans blinked in surprise as Apollo shrunk, jumped in her arms and snuggled with his girlfriend like he wasn't just doing that. He frowned and scoffed.
"what a pet." Sans said, frowning and crossing his arms as he rolled his eyes. A small blast hit him in the head and he turned, furious at Apollo. But Frisk was already going with him to the kitchen.
"tsk. stupid apollo."
It was morning when he woke up. Frisk was already out of bed. He rolled on the floor and got up, walking towards the bathroom. Frisk was inside, brushing her teeth. Apollo was happily sitting in the bathtub. Sans ignored him again, an awful move to do if you ask me, and went over to hug Frisk behind her back.
"morning." He mumbled. Frisk giggled as she spat out the toothpaste and mouthwash.
"Morning, sleepy bone-head." Frisk said with a bright smile. Sans chuckled.
"man, you're way too energetic for 7 in the morning." Frisk shrugged.
"I didn't binge any shows last night unlike someone here...Still can't sleep well?" Sans shrugs.
"it's not nightmares as they used to be back when we both had them...but the insomnia kind of stuck with me." Frisk sighed and turned around, rubbing her thumb on his cheek.
"I'm sure we'll find a way to make you bone-head properly sleep." Sans chuckled.
"yeah...i know..." He said, smiling. He then slid his hand on the side of her head, his thumb resting behind her ear and he tried to pull her in for a kiss. Frisk closed her eyes but Apollo woke up to ruin everything. The bone-monster jumped up and managed to get the shower head to turn on and splash both of them. Frisk spurted and Sans backed away growling.
"stupid little-" Frisk moved her bangs aside to get a better look at Apollo. She frowned.
"How did you even manage to do that...Agh- i need to change..." Frisk said, pouting. Her now damp clothes were showing her curves and underwear perfectly. Apollo growled and covered Sans sockets with his tail.
"ACK- hey! watch it you little pet-- ack!" Sans fell back, slipping. Frisk then was nudged out of the bathroom.
"FINE! I'M GOING TO CHANGE! SHEESH!" Frisk said to Apollo. The monster finally let Sans go. Sans looked at him unimpressed.
"YOU! are a demon." Sans said, pointing at Apollo. The tiny pet grumbled happily, smirking in triumph. Sans rolled his eyes at that.
They were walking together from school. Sans was eyeing Frisk. Why...? Because sometimes you need to admire beautiful things. Her smile and twinkling eyes, that skipping step of hers that brought her head just a bit closer to the clouds was making him swarm with butterflies. She turned around to him and smiled.
"Admiring the nothing again?" Frisk asked, amused. Sans chuckled.
"baby bones...you are not 'nothing' so i'd say i am admiring quite something alright~" He said with a wink. Frisk blushed and rolled her eyes.
"Cheesy." he chuckled and they continued walking. He slipped a hand around her waist and pulled her close.
"wanna take a shortcut~?" Frisk smiled and giggled.
"Alright." He teleported them to the living room and he was about to lean and steal a kiss as well when a butcher's knife went right past their heads. Frisk looked in disbelief towards the kitchen, but in the doorway only stood Apollo.
"How did....Sans, are you playing a prank on me?! Seriously?! Ugh!" She rolled her eyes and started leaving. Sans stood there, frozen.
"WAIT! i swear it wasn't me- IT WAS APOLLO!!" Frisk scoffed.
"Yeah yeah, blame it on the pet. Aww, I'm so sorry he's blaming you, baby!" Frisk said, hoisting the demon up and she started walking with it upstairs. Sans looked in disbelief as Apollo stuck his glowing tongue out at him. Sans groaned and flipped the bird at Apollo. The pet immediately started whimpering.
"Awww...Its ok, baby. The mean skeleton can't hurt you~" She said as she closed the door.
"MEAN?! HOLD ON--!" But the door was already closed. Sans face-palmed. That's when he heard a sip from behind him. He yelped and jumped back only to find his father sitting in the arm-chair.
"oh...it's just you old man." Gaster smirked and twisted his mug, showing that on it was written 'Team Apollo #1'. Sans frowned.
"YOU'RE SUPPOSED TO BE ON MY SIDE! OH FOR FUCK'S SAKE!" And he started walking away.
He made sure that this time? The cat, dog, pet- whatever Apollo was- DRAGON! Idk- would stay away. He made sure it wasn't in the room and the door was closed. Frisk was giggling as he was pulling her close. They were laying in bed, just before they were going to sleep.
"What's up with you??" She asked, amused, at how clingy he was. Sans frowned.
"nothing. now please me." Frisk's face burned at how bold that was and how not kid friendly it sounded.
"E-Excuse me?!" She asked, blinking in surprise. Sans chuckled, seeing her flustered and smirked with a hungry look.
"exactly as you heard, sweetheart." Frisk felt her chest go all fuzzy when he said that, a small tinge of a growl behind it. He let his phalanges slide around her throat and he pulled her down. Frisk's eyes widened as it happened and she let a small moan out when he slid his tongue in her mouth and squeezed her neck. He was being possessive now. Frisk could feel the jealousy through the bond. But it was addicting. Frisk leaned back, panting. Sans groaned.
"ah- fuck- sorry, i got carried away--" He said apologetically. Frisk's eyes lit up.
"Do it again!" Frisk said. Sans stiffened, spurting in surprise, his socket going blank.
"wha-- OW!" A small bone hit Sans, making him roll off the bed and Frisk blinked in surprise. Suddenly a bit tail was around her waist and Frisk got picked up by Apollo.
"W-Wait! APOLLO--" And the monster left with Frisk, probably taking her to Gaster's room. Sans scoffed.
"and i had her this time..." Sans said, frowning. Then he looked at his hand and flushed. Yeah...he wasn't sleeping tonight. Not to mention now he had a bone-hard itch.
He woke up and made his way downstairs to the kitchen where Apollo was sitting on the counter and Gaster was leaning over his coffee. Sans gulped.
"A choking kink? REALLY?!" Gaster said with narrowed flaring eyes. The tiny monster's eyes flared as well, the bones on it's back and tail becoming spikes. Sans gulped again.
"maybe i should g..." He stopped as Papyrus was waving a big bone behind him.
"NO, I DON'T THINK YOU WILL LEAVE. YOU BRUISED FRISK! YOU SHALL PAY FOR YOUR CRIMES!"
Frisk flinched as she heard what was happening downstairs.
"You poor poor sinner..."
