(A/N: BEWARE! FLUFF (or whatever word would be used for it (lemon, fluff, whatever)) UP AHEAD! YOU HAVE BEEN WARNED!)
(Then again, this is my first time writing stuff like that, and I don't read lemon stories unless they were put into a story so I dunno if it's good or... okay, enough with my rambling. I'm sorry 😅😂 Please read on)

Sans' P.O.V

When the beam of light disappeared, we were back on Earth, and the both of us were instantly drenched in rain. I looked around to see what part of town we were in. We were in an alley, and luckily none of the mortals seemed to notice us. I looked back at Frisk and saw her leaning against the side of one of the buildings.

"are ya okay, kid?" I asked, moving closer to her side.

"Yeah," she replied, looking up at me with a dull, sad look in her eyes. "Just still trying to take everything in. Why did you call me kid?" she asked after a moment, changing the subject. "You know I'm eighteen, right?"

"technically no, and i called ya that 'cause of how ya act to everythin' on earth. what, do ya not like it?"

"I don't really mind it. It's just strange to be called kid at this age."

"then, how 'bout kiddo?" I asked, moving behind her and gently rubbing my skull against her neck.

"N-No," she mumbled pathetically.

"what about frisky?" I continued, lowering my voice. I hung out my tongue and let my drool roll down her skin. I felt her shiver, and I could see she was blushing hard. "frisky bits?"

"You bonehead," she whispered, seemingly unable to take anymore, and turned her head to kiss me. I kissed back.

I yearned for her. Everytime I got into this kind of mood, I craved her. Not just because of the fact that I need her energy to live, but also everything about her. My left, magical eye kicked on, and I could feel the heat come to my own body. I broke the kiss just for a second so I could get my shirt off. I could tell she didn't want to part, but I quickly resolved that after I had taken it off.

That was when a fleeting thought came to my mind. I had left my jacket in her sister's apartment.

i'll just buy a new one. unless that angel-demon decides to deliver it to me herself.

I pinned Frisk against the wall, moving my hands under her shirt and up her back, feeling every inch of her delicate and soft skin. I could feel her hands moving from one rib bone to another, slowly and lightly touching it just to torture me.

"ya play unfair, ya know that?" I asked, sounding completely out of breath.

"Yes, but so do you," she replied, suddenly taking off her own shirt as though she couldn't stand the heat any longer. "Will anyone notice us?" she asked as I started kissing along her collarbone.

"nah, something like this is normal on earth," I said between kisses. "only difference between us and a normal case, though, is that i'm doin' this all for love, not for the energy."

I could feel her breath on the top of my skull as I wandered close to her breasts. However, I took note of her worry, grabbed hold of our clothes with my magic and teleported us where I knew we would be left alone.

A little place of my own Grillby had lent me when I was eighteen and wanted out of the house while my father was there with whatever chick he had brought with him. I tried not to focus on that now.

Frisk fell backwards onto the bed as she realized the wall wasn't there anymore to support her, and I landed just inches above her. In the dark, I could easily see the faint glow of our souls. I resumed my task before I teleported, and also ran my hand up and down her side, slowly torturing her like she had done to me earlier.

"Told you so," she said between her moans. I simply chuckled and decided to move down further, running my tongue across her stomach. She gasped, and I felt her suck it in, as though that would stop it. I just did it again, moving down just a little more every time.

Unfortunately, and seemingly timed perfectly, a knock sounded throughout the house. I stopped and looked towards the bedroom door in annoyance.

"Ya just gonna stop there?" Frisk asked, mimicking how I talk.

"unfortunately i have to." I moved back up to her lips and kissed her before standing up as I heard another knock. "stay here, just in case, alright?"

"Mhmm."

I walked out of the bedroom, glancing back at Frisk before heading to the front door. I looked through the little hole and saw not only my best friend, but my brother and our friends as well.

"shhhhit," I whispered before unlocking the door and opening it. "heya, guys. didn't expect ya to show up here."

"BROTHER, WHERE IS YOUR SHIRT?" Papyrus asked right out the gate.

"in the bedroom," I answered slowly, trying to think of a way around the truth. "it got too warm."

"WE CAN'T FEEL HEAT OR COLD, SANS."

not temperature wise, no.

"Erm, Papyrus, dear," Mettaton said. "Why don't you and Undyne cook us something for later when we listen to what happened in Heaven?"

"OH OF COURSE! THE ROYAL ANGEL PRINCESS HAS YET TO KNOW OF MY COOKING PROWESS. TO THE KITCHEN, UNDYNE!"

"Yes!" Undyne shouted. "Let's get this cooking started!" She threw something blue in my face before following my brother into the kitchen. It was my jacket.

"W-We brought that with us," Alphys said as I put it on. "I kinda f-figured you would want it."

"thanks, alph."

"Now tell us," Grillby spoke up, speaking for the first time since he arrived, a smirk on his flaming face. "Who did you play with?"

My skull flushed blue instantly. "w-wanna get it out there f-first, huh?"

"We know the real reason why you don't have a shirt on and said that it was in your bedroom," Mettaton added.

I rubbed the back of my neck, finding myself in an awkward position. "no hidin' it, huh? if ya must know... it's, uh, frisk, the angel princess."

"So all that earlier was for real?" Alphys asked.

"of course! only a death or a break up can cause a spark of energies to be broken."

"How did meeting her parents go?" the flame monster asked slyly.

"i woulda been here much sooner if it went as smoothly as i hoped."

"Well, you can talk about that at the table. For now, why don't you get Frisk and have her join us?"

"fine. and for the record, you guys are a serious buzzkill." I walked back to the bedroom and closed the door, letting out a sigh. I looked up and saw Frisk wearing one of my shirts, which was loose on her. She had taken off her shorts, which left her undergarments and leggings to be left on her body besides my shirt.

"holy fuckin' shit, you're hot," I said, accidently letting it out. I thought it was such a shame she was just going to put it all back on. My tongue hung out like a dog's as I stared at her, and the little specks in my eye sockets turned to hearts.

"Oh, you like this?" she teased, delicately walking over to me, her wings slightly outstretched. "Who was at the door?" she asked as she ran her fingers back and forth on the back of my neck.

"what you're gonna hate to hear," I said sadly, trying to resist the temptation Frisk was practically giving me.

"What?"

"guests who decided to stay for a bit to hear what happened after we left your sister's."

"Aww. And right when it was getting good."

"c'mon. get dressed. maybe we can get to the good part after they leave."

"Fine," she sighed. "Tell them I'll be out in a moment."

"love ya," I whispered in her ear. She smiled.

"I love you, too. Now get back to the other's before they start suspecting anything."

She stepped backwards and I hurriedly got out of the bedroom before I got myself into anything. Grillby, Mettaton, and Alphys weren't hanging by the door, so I assumed they were in the kitchen. I zipped up my jacket, realizing I hadn't bothered to put back on my shirt. I allowed my wings to trail behind me, since everyone in the house knew what everyone was.

"what'cha cookin'?" I asked as I entered the kitchen.

"SOME OF THE GREAT PAPYRUS' SPAGHETTI, DEAR BROTHER," my brother answered me.

as usual.

"When are you going to tell him that angels of either kind don't have to eat?" Grillby whispered to me.

"ya own a bar, so i don't know what point you're tryin' to make," I whispered back.

"IS THE ANGEL PRINCESS COMING?"

"Yeah, I'm here," Frisk said before I could speak for her, dressed once again in her own clothes. She came over to me and I wrapped my arms around her.

"DID YOU HAVE A NICE PLAYDATE WITH MY BROTHER? I KNOW HOW LAZY HE CAN BE SOMETIMES."

"P-Playdate?" Frisk stuttered, blush covering her face. I pulled my hoodie over my head, too embarrassed to show my face. "What makes you say that?"

"I HEARD GRILLBY MENTION PLAYING, AND SANS ANSWERED WITH YOUR NAME. I DON'T SEE WHAT IS SO EMBARRASING ABOUT A PLAYDATE. ALTHOUGH IT COULD BE BECAUSE YOU'RE BOTH ADULTS."

he doesn't even know what it fuckin' means.

"Papyrus is too fucking innocent," Frisk muttered under her breath, sounding a little relieved. "Um, yeah, it was fun," she added in a louder voice.

I felt practically paralyzed by her response, blushing hard.

"ARE YOU ALRIGHT, SANS?" Papyrus asked. I lifted up my hoodie with one of my hands and saw that he was standing over me and Frisk with a couple plates of spaghetti in his gloved hands.

"uh, yeah, bro," I said, taking one while Frisk took the other. "just thinkin' about everything that happened these, what, past few hours?" That wasn't entirely a lie, since all of that happened within that period of time.

"OH, WELL, SPEAKING OF WHICH, WHERE'S THE PRINCE? YOUR BROTHER IF I REMEMBER, RIGHT PRINCESS FRISK?"

"Yes, he is. And please just call me Frisk. It's weird when my friends call me 'Princess' everytime they talk to me."

Papyrus gasped, his wings appearing and quivering. "WE'RE FRIENDS ALREADY?! I MEAN, OF COURSE WE ARE!" he added, recomposing himself, spreading out his wings until they were their full wingspan, which was actually quite an impressive size. "I AM THE GREAT PAPYRUS! WHO WOULDN'T WANT TO BE FRIENDS WITH ME?"

"isn't that what i always tell ya?"

"YES, BUT YOUR MY BROTHER. YOU ARE HAVE TO SAY THAT. BESIDES, YOUR METHODS OF FRIENDSHIP DON'T MATCH UP WITH MY VERY HIGH STANDARDS."

"ouch."

"And yet here I am wondering what happened to those two kids who were too scared to talk to anyone," Undyne said wistfully, a little tease in her voice. "Especially the younger one."

"UNDYNE, YOU PROMISED NOT TO MENTION ANY OF THAT. NYO HO HO! MY REPUTATION WITH THE PRINCESS OF ANGELS IS RUINED!"

"Just because Undyne said that doesn't mean I don't like you any less Papyrus," Frisk said, trying hard to contain her laughter.

"WAIT, REALLY?!"

"Sorry to ruin the mood," Grillby spoke up.

"like ya haven't already done that," I mumbled.

"But how are you here without the prince? Surely none of the royal family would let their princess come and leave Heaven with a love angel."

"they... didn't. not willingly. we were trialled, us and the prince. the king said they were doin' somethin' different, at the end, and each of us had a black cloth over our heads. he said that they were taken off if we were 'innocent' and left on if we were guilty... mine was left on an' frisk's and the prince's were taken off, as expected."

"H-How are you here?" Alphys asked while Undyne was busy stuffing her face with spaghetti.

"I saved his ass, like I've had to a few times before," Frisk answered.

"thank you, by the way. but don't forget who got us out of that place."

"I was the one who led you out of that building because you were too low on energy to fly straight!" she argued, stepping out of the hug so she could turn and look at me. I set my plate on the table, knowing I couldn't eat anymore, and Frisk did the same. We didn't break eye contact.

"are ya blamin' me for bein' born a love angel?"

"No, I'm blaming you for how senseless you are with your own energy!"

"like i could stop them from injecting me with one of their needles! the only reason why i retreated from the second one is because it would have killed me. the others i just didn't want to make it an instant execution."

"OH MY GOD! CAN YOU GUYS JUST KISS AND MAKE UP ALREADY?!" Undyne shouted, slamming her summoned spear through the table, having finished eating her spaghetti.

"w-wha-?" I glanced up at the fish angel before Frisk covered my head with her wings, cutting me off. I looked back towards her.

"What are you so scared about?" she teased, draping her arms over my shoulders, our argument appearently forgotten so easily. "It's just another kiss."

"one that is in front of my friends and brother," I mumbled, trying hard to calm my voice after our outbursts.

"I kissed you in front of my brother."

"that was a matter of life or death. plus," I sighed, "i lose myself when we kiss. i crave for you, and after what happened earlier, i doubt i could control myself. that's not somethin' ya show, or do, in front of friends and family."

"Oh." She lowered her wings, and eager faces were the first thing that caught my eye socket. "The argument's settled," she said briefly, breaking those eager faces.

"Sooo... are you two not going to kiss?" Undyne asked, somewhat disappointed along with Alphys.

"No, because my show is on very soon darlings~!" Mettaton said, pride in his voice.

"it's that late already?" I whispered, rubbing the top of my skull.

"I thought it was later," Frisk whispered back. "By the way, what's a show?"

"it's a form of entertainment that you can watch from a tv."

"What's a TV?" I took her hand and led her into the living room, where everyone else was already congregating.

"I think I'll watch it at home," Grillby said, hanging by the front door. "I stayed here longer than I planned anyways."

"it was nice havin' ya, grillbz."

Everyone else said their goodbyes as the flame elemental opened the door, waved, and left.

"SANS, HURRY UP OR YOU'RE GOING TO MISS THE SHOW," my brother ordered.

"i doubt missing a second of the show will somehow confuse me like watching an episode of an anime without starting it from the begining." I sat down on the floor and Frisk sat on my lap. I unzipped my jacket and took it off in order to wrap my wings around her along with my arms.

"WE'VE ALWAYS WATCHED EVERY SINGLE SECOND OF EACH SHOW, SO DON'T GO RUINING OUR STREAK FOR YOUR STREAK OF LAZINESS."

"whatever keeps ya happy, pap."
