You stared down at the sleeping skeleton, watching how his closed eye sockets had the slightest twitch to them every so often. His cheeks had a slight blue glow to them. Pleasant dream? Too warm? Either way, that was probably going to change very quickly. You licked your lips, trying to decide exactly what your plan was. It was hard enough to get into this position in the first place-on your hands and knees, hovering over him in bed-without waking him up. Now you wanted to wake him up… but you couldn't decide on how.

Should you scare him awake? Revenge for all the times he spooked you? Or did you want to be extra sweet? Today was the day you chose for him after all. You were so close to him, it would be easy to just shower him in kisses to wake him up… but the revenge just felt all too tempting.

"Fuck." You whispered to yourself, hardly a sound leaving your lips. You couldn't decide.

"Mmmhmm?" Apparently you wouldn't get to, either. Sans mumbled for a moment, shifting in his position slightly before his eyes opened.

"Oh! San-ACK!" You started, and were quickly interrupted when your skulls collided. "Owfuckingshit-" You fell back, holding your forehead. Sans appeared to do the same thing, grumbling and pressing a skeletal hand to his head.

"Ngggghh… Vertebae?" He groaned, looking confused.

"I'm so sorry, Sans!" You quickly knelt beside him, littering his forehead with kisses. That seemed to confuse him even more.

"W…what?" He put a hand to your shoulder, pushing you back slightly. "What's with all of the kisses? I mean, the bump to the head, but… Why were you on top of me just then?"

You felt some heat rush to your cheeks as you smiled, nervously biting the side of your lip. "Well, I wanted to surprise you. Today, I decided, is your day." You shifted your weight on your knees, anxious about what he'd think.

"My day?" He raised an eyebrow—it still caught you off guard that he could do that sometimes—and sat up using his elbows as support. "You mean, my turn for Other's Day?" A crooked grin made its way to his face.

You smiled even bigger, nodding excitedly. Damn, you felt like a child. "That's right, lazybones. Get your ass-less ass out of bed! It's my turn to treat you." You rapid-fire some kisses on his cheeks, earning a laugh from him as he half-attempted to get out of the way.

"Heheh… Okay, okay! Give me a minute!" He gently pushed you back, and you gave him one final kiss before scrambling off of the bed.

"Comfy clothes only!" You playfully ordered, pointing a finger at him before heading to the door.

"Like I ever wear anything else." You heard him chuckle behind you as you left the room and closed the door. You couldn't stop the stupid smile from taking hold of your face, your cheeks already starting to ache.

Game on. You quickly rushed to the kitchen, checking on the baking goods in the oven before pouring the tea you had already prepped. The baked goods didn't need much longer, and the tea was perfect. You smiled to yourself, checking the counters over for anything you'd forgotten.

You eyes rushed across the counter that separated the kitchen from the living room, and felt them widen. How did that get there?! You quickly swipe the small box from counter, looking wildly around the living room for someplace to put it.

"So… what's the plan for today?" Sans' voice asked, startling you. You flailed, quickly scrambling to put the box under the TV stand before standing up, acting casual as you possibly could.

"Ahahah… Well, first I made some tea!" You motioned to the mugs, which he noticed. "And… I figured we could use some alone time together. A lot has been happening lately, and I figured we needed a good day to chill." You said with a slightly higher pitched voice, half asking his opinion on the thought.

"Heheh, that does sound rather nice." He smiled, eyes brightening slightly. "How'd you convince Paps to give us time?" Sans asked.

"I bought Mettaton and him an all day treat at the new monster-friendly spa that just opened up. He decided to make it an Other's day as well." You felt rather proud of yourself at that. "He won't be back until tomorrow, he promised."

"Well, that's a relief. No interruptions." Sans appeared next to you, giving you a quick kiss to your cheek. He teleported back to the kitchen, grabbing his mug of tea.

"I… I originally was going to get us tickets to an observatory, but the closest one to here is miles out of town, and it's already booked by some school for the night." Your hands tied into themselves. "So I came up with a backup plan! But that's a surprise, so…. You'll see later!" God you felt like such a child. Sans couldn't help laughing at your fidgeting.

"Anything you have planned is going to be great, Vertebae, I'm sure." He sipped on his tea. "Hm. This is new."

"You like it? Undyne said it was her new favorite, so I decided to give it a try." He nodded to your question, taking another careful sip. It still awed you that a skeleton could enjoy tea as much as Sans could. Right. Enough chitchat, time for business. "I bought a copy of one of my favorite games for us to play today, I figured you'd like it." You walked further into the living room, sitting on the mattress you had pulled out earlier, and crossed your legs.

"Is it the one you kept trying to tell me about but ended every sentence with 'but I can't tell you that because of spoilers' and then would tell me about the amazing fanfic you read once and continued to try and avoid spoilers?" He asked, earning a laugh from you.

"Whoops. Yeah, that's the one." You giggled a bit, patting the mattress. Sans walked over and put his tea on the floor beside the mattress, sitting down himself. You turned on the TV and passed him the controller. "It's a simple game, once you figure it out. You like quantum physics, or some nerd stuff like that, so you should like it."

He pressed the start button, and the sound of machinery that was accompanied to some electronic ambient music was switched to a small radio tune that was rather familiar to you. He looked around the small glass room, giving you a look of confusion in real life. You motioned to him to keep playing the game, so he clicked on a mug and threw it into the toilet that was in the room. There was a "boop" sound and a female's electronic voice echoed from the speakers.

"Hello, and again, welcome to the Aperture Science Computer Aided Enrichment Center."

.

"Whoops."

"GOD DAMN IT SANS." You dropped your controller and threw your hands up in the air. The sound of your robot exploding under the pressure of the rising floor mocked you, making you even more frustrated. Sans couldn't stop laughing, he fell backwards and was holding his ribcage.

"Blue receives five science collaboration points." The cold robotic female voice added.

"DON'T ENCOURAGE HIM!" You yelled, pointing a finger at the TV despite it not being able to respond to you.

"Shhh…. There there… I understand your frustration." Sans wrapped his arms around you, attempting to hold back his laughs. Your teeth ground together as you looked over your shoulder at him, only making him laugh harder.

"After everything I've done for you…. Betrayal." You whispered the last word. You weren't really angry, of course, but he seemed to love how upset you were acting over your robot getting crushed for the ump-teenth time after being promised that he was done. "I'll show you what it's like to be crushed." You flopped back onto him, and you felt him let go of the hug to flail.

"Wait nonono—ack!" He struggled under you, and you pushed yourself with your legs to completely be on top of him. Your foot kicked one of the dishes that was on the floor, but you paid it no mind. The mugs were long empty.

"Revenge." You whispered in the same tone as before, breaking down into laughs as you turned around and trapped him under you. Your hands grabbed him where his armpits would be, and he suddenly jerked with a snort, flailing extra hard for a moment. "Wait a fucking second." You froze.

He paused, the look of horror slowly making its way to his face. "No." He demanded, already knowing where you mind was headed.

"Are you-"

"Nah."

"actually-"

"Negative. Nope. Nu-uh."

"Ticklish?!" Your fingers quickly wiggled against his ribcage, and he almost squeaked as he flailed under your tickle attack.

"S-S-Stop stop stop noooooo!" He shrieked and tried to suppress his laughter by snapping his jaw shut, but it just made you want to tickle him more.

"REVENGE. MUHAHAHA!" You intimidated an evil laugh, not lightening up your attacks in the slightest.

"Pl-ease! I give up! I need! To! BREATHE!" He struggled helplessly under you, blue starting to shine under his left closed eye. You decided to give him a quick breather, and stopped the attack. You stood over him on your hands and knees with a shit-eating grin on your face. He inhaled, eyes finally opening.

"Do you surrender?" You ask, feeling rather smug.

He took a few breaths, calming down. "Only if you do." He suddenly leapt, wrapping his legs around your waist and twisting, somehow managing to get you on your back and him above you. You had a moment of fear before he flopped down on you, not bothering to return the tickle attack.

"I accept your defeat, then." You wrapped your arms around him, pulling him close to snuggle, giving a quick kiss to the top of the head. He exhaled, relaxing more into your body.

The two of you stayed that way for a long while, listening to the ambient music from the game play as the TV dimmed. You were actually falling asleep again, you were feeling so relaxed with the skeleton on top of you. That was until you felt a slight pressure at your collarbone.

"Thank you for today, it's been really nice." Sans said quietly, apparently getting sleepy as well. He kissed your collarbone again.

You smiled. "Don't thank me yet, there is still time for more surprises. If you want, that is."

"Hmm? Like what?" He asked, giving you another kiss somewhat more between your collarbones. Looks like he already knew what you were aiming for.

"Well… I figured I could try and return the favor of my Other's Day." You nervously smiled, and you felt heat rush to your cheeks.

Sans chuckled, lifting himself onto his hands and looking down at you. "Oh really?" He asked, grin making its way on his face. "I don't think I would mind that at all."

You bit your lip in a smile, feeling excitement bubble in your body. "Okay, let me just get ready." You leaned up to give him a quick kiss, and gently pushed him to the side so you could escape from under him. You quickly gather the dishes that littered the ground and dropped them off in the kitchen. On your way back to the living room you grabbed a box of incense from the counter and lit one of them, making sure it was properly set before quickly rushing to the box under the TV stand.

"Huh. Didn't actually expect you to get so ready for this. What's that?" Sans asked, pointing at the box. You pulled out a small black box from it, carefully fitting it over the small stand with a lightbulb before putting it on the floor as close to the middle of the room you could get, yet a safe distance from the mattress.

"You'll see." You made sure the things were clicked together, pulling out the one button remote for it, and setting it to the side of the mattress. He looked completely interested in it, but you wagged a finger at him. "Don't touch it, I'll be right back." You quickly left to the bathroom, washing out your mouth quickly and messing with your hair for a moment, before rushing back. You pulled the curtains to the living room closed, and walked to the mattress.

"Okay." You stated, standing in front of Sans. "I… uh." Your nervousness was showing brighter than daylight, even in the dark room. "Just tell me what not to do." You gave a slight laugh, trying to relieve the stress.

Sans laughed, relaxing back into a couple pillows. "Heheh… Don't bite it, don't swallow it, and most of all, don't be so damn nervous." He laughed more. "Just do what you want. If you feel uncomfortable, we can stop. If I feel uncomfortable, I'll let you know." His eyes shone brightly at you, and you nodded, licking your lips nervously. Right. Calm down. You are just going to be making love to his Soul. No big deal…

You crawled onto the mattress, hovering over him, trying to look a least a little sexy despite your nervousness. It seemed to work, since his eyebrows raised slightly. You quietly swallowed, leaning down and giving him a kiss on the edge of his jawline. He angled his neck, and you took the opportunity to kiss his neck bones. You could feel him smile slightly, giving you a slight confidence boost. Your tongue trailed up the bones, sending a shiver down his spine. Your hands were not still while you did this, and were slowly rubbing his ribs through his shirt, gradually trailing down. Your mouth sucked on one cervical vertebra, and Sans' breathing hitched. His hands grabbed the edges of his shirt, pulling at it slightly. You release your hold on him, helping him get his shirt off before continuing the kissing and licking.

You couldn't help but to feel accomplished at every shiver and gasp he released, wanting to hear more of the beautiful sounds. Leaning back, you sat on his pelvis and looked down at him in the dark, only really able to see his bright eyes and the slight blue of his cheeks in the darkness of the room.

"Ready?" You asked, running your fingers over his ribs, earning more shivers. Sans nodded, smile growing on his face. A few of your fingers rubbed a large circle around his sternum, slowly, before turning into a fist and pulling up. Unlike when your Soul was summoned, instead of appearing in front of the chest, his bright blue glowing Soul appeared within his ribcage. You let a hand rest on the inside of his spine for a second, and you watched as Sans was carefully watching it. Your pointer and middle fingers imitated walking up the inside of his spine towards his soul, and you felt Sans' back arch at the action.

You held back a giggle, and carefully grabbed onto the blue Soul. Sans sharply inhaled, making you pause for a moment. "You good?" You asked, worried you did something wrong.

"N-no, I mean yes! Sorry, you're fine. It's just… been a while since anyone touched that." He laughed, embarrassed, covering his face with his hands. "Keep going, sorry."

You smile and lean down to kiss his ribcage. "Don't be sorry, love." You straightened up, carefully pulling his soul out. This was the first time he let you hold his Soul after all, you wanted to make sure he enjoyed it. "So… how is this?" You asked, using your free hand to rub along it.

He immediately startled, arching his back and leaning more into the pillows. "That… hnng… feels good." He closed his eyes, his hands seeming like they didn't know what to do with themselves.

You smiled, bringing it close to your mouth, and giving it a gentle kiss. You saw him jerk for a moment, before relaxing into the mattress again. "And this?" You brushed your lips against it, keeping careful watch on his reactions.

"It's nice… It feeeeeeeeelsohmygod…" You gave a long lick to his Soul, startling him and making his words rush together. You gave another lick, trailing up as much as you could, watching as his hands grabbed at your legs, then at the air, before gripping the bed sheets.

You wiggled your tongue against the softness, watching as that sent him gasping as he squirmed under you, your groin getting rubbed at from his pelvis. The Soul was getting rather warm, you noticed, but you didn't stop. You made large circles with your tongue, carefully leaning over to grab the one-button remote from the side of the mattress without Sans noticing. You pressed the small yellow button, waiting a moment before looking up, smiling when it worked.

"Sans." You whispered into the Soul, sucking slightly in the middle. Sans gasped out, hands grabbing at your legs and fingers digging slightly into your thighs. You gave another lick to the Soul before pressing a thumb to the middle, gently rubbing it. Leaning down, you kissed along Sans' ribs to his neck, and up to his jaw. "Look up." You whispered where his ear would have been, before kissing all along his cheek.

He moaned, and you felt him look up. He startled, breath immediately leaving him. "Oh… Hnng… My god…" You dug your thumb into the Soul as you sucked at his neck again, feeling as his body arched and strained. You smiled into more kisses, looking up at the small light dots that littered the ceiling of your living room. Fake stars are a fine substitute for real ones if it means you don't have to leave your apartment.

You looked up at him, seeing how his eyes were darting from one star to the next, straining and having trouble not shutting every so often from all of the pleasure being received. Sitting back up, you went back to licking the Soul, pressing harder with your tongue. Sans' hands gripped your legs tighter, he seemed like he was having a hard time breathing.

"I'm… ooooh I'msofuckingclose." The words hissed between his teeth, his pelvis grinding against your groin automatically as you licked more intently.

You don't aim to disappoint, so one of your hands started rubbing the inside of his ribcage along his spine, and you started sucking the Soul from the middle, using your tongue to rub at the same time.

"Ah….hhhhh…. hhhhhnnnngggggggg….." Sans inhaled… inhaled… and groaned with a shiver as his body shook, his fingers grabbing tight and losing grip within the same second. The Soul shuddered, and was suddenly feeling very wet.

Your mouth released the sucking, and you felt some of the wetness cling to your lips. Rubbing at your mouth, you pulled your hand back to see the lightly glowing liquid trail between your fingers. "Hmm." You wondered out loud for a moment, before putting your fingers in your mouth.

It tasted… strange. Sweet and salty at the same time, yet completely different from anything else you could describe. You looked over the Soul, lifting fingers from it and seeing the same liquid coating the entire thing. You gave the Soul another lick, curious.

"AAAAH! S-ssssss-ssst…. Blue….blue… please…" Sans, who had been trying to catch his breath and was lying sprawled on the mattress up until this point, suddenly flailed and cried out, grabbing your wrist and stopping you mid-lick. "'s too sensitive..." he breathed out shakily. You nodded, slowly lowering the Soul back inside of his ribcage and letting it go. It simply hung in there, as if it was suspended.

He leaned back, breathing hard still, but cracked his eyes open to look up at the fake stars. You licked your lips, getting the last of the glowing liquid off. Sans glanced at you, giving a big goofy smile before moving an arm up. "Come on, look at the stars with me." He tilted his head.

You smiled, laying down next to him and resting your head on his shoulder, using one of the free pillows for more comfortable support. Your hand automatically reached up inside his ribcage, gently holding onto his Soul. "Today was a good Other's Day then?" You asked, ever so slightly stroking that coalesced magic.

Sans sighed with a smile, turning his head and giving you a lazy kiss. "It was the best one I've ever had. Thank you."
