In the Guest Room... (A/N: Yes, I may have an office with my apartment. But upstairs, there are guest rooms so I'm having the gang to stay over for the night.)

Everyone decided to have a sleepover - Yeah!

Undyne: Let's watch a movie!

Alphys: There's a few movies here... *looking through* There's Highschool DxD, Elfen Lied, Ikki Tousen and... *gasp* How about Junjou Romantica?

Sans: Seriously, you got movies on females with huge bosom and now you got a yaoi movie?

Alphys: Oh, sorry about that. There are my favourite movies I like to watch...

Mettaton: Oh yeah, the moment when you were basically squealing when you saw the two guys kissing.

Alphys: Shut up! *smacks him in the head*

Sans: *gets up and leave*

Papyrus: SANS, WHERE ARE YOU GOING?

Sans: I'm going to check on Frisk.

Papyrus: BUT AZURE IS LOOKING AFTER HER WHILE SHE WAS SLEEPING.

Sans: Nah, it's cool. *walks away*

Me: *walking out of the kitchen with tissue boxes, a bottle of holy water and bleach?* Huh, where did Sans go?

Alphys: Frisk's room. *insert the CD of Ikki Tousen*

Me: Oh, okay.

Napstablook: hey azure..... what's that for?

Me: The chapter. *sprints into my room* Oh lord...

Cut-out Scene: Sans is watching Frisk sleeping with a hint of lust in his heart pupils.

What's up Buddies! I hope you did your prayers at the church because right now this is a chapter you are expecting - the answer is Smut (Sorry for those who didn't win - clearly there is no winner). Now, I hope you figure out how old Frisk is? Because she's 17 years old and Sans will be 20 years old, legal age right? So, either it's like smut or nfsw depending on the cringe. So, be prepared to be determine. If you can't take anymore, take a break from it. Also three things: 1) Have a tissue box with you. 2) Use holy water if you can and 3) If emergency, use the bleach (don't recommend for drinking but for the eyes). Okay, you dirty sinners, I hope you enjoy this~

(WARNING: It contains sexual contents and strong language! Btw, if you are under 18, recommend you skip this chapter IMMEDIATELY!)

Frisk's P.O.V

"Finally, I'm here..."

I was standing on the doorstep of the Skelebros's house in Snowdin. It was finally the time for me to go in there and do whatever Sans ask me to do for tonight. I raised my hand to the door and knocked - there's no answer. I knocked again and still no answer. I twisted the doorknob and pushed it - the door was opened. I stepped inside and looked around the house.

"Sans! You in there?" I called out into the empty house - there's no reply. I searched in the kitchen - not there but I quickly check the time that read 10:35 p.m, the living room - no, Papyrus's room - no. I came to Sans' room and looked inside - nothing. I walked inside and saw a note on the ground. I bend down to pick it up and read the letter.

Hey Frisk,
Sorry about that I wasn't here, I just left a bit early because I'm going to see Undyne for a bit to check how Papyrus is doing. So if you are waiting for me, please wait in my room, okay? Don't forget what we're doing tonight. I'll see you when I get home.

- Sans

I gulped nervously as I put down the note and began undressing myself. I took off my sweater, then my shirt, my shorts and my boots. Now I was left with my lacy black bra, underwear and below-knee socks. I feel so embarrassed to be half-naked like this, this is the first time to be like this in front of him. I shivered as I imagine him looking over my body, mesmerized how beautiful my body look, and having his hands roaming over me sending pleasurable touches on my delicate skin. Somehow, my body are already tingling and the heat radiating from my skin as I thought about him more. I was cut off dreaming when I heard a very 'sexy' sound that got my bones rattling - a wolfwhistle.

I stiffed up a bit before turning around shyly to look at where that sound was coming, and yes, it was him. He was standing there, leaning against the doorframe with his arms crossed over his sternum. His pupils held a hungry lustful look in his eyes as he trailed them up and down on me, admiring the features. I saw the blue tongue made by magic slithering out from his mouth and slide across the top teeth to make it look like he's licking his lips. I heard a deep chuckle from him.

"Already excited huh?" He asked seductively with a husky tone. I blushed deeply in shades of red and slowly nodded in response. He smirked and slowly made his way over to me. The closer he got, the more I feel myself getting warmer and my heart beating hard like a drum. He stopped in front of me and gently took my hand in his. He raised my hand up to his teeth and brushed against the soft skin while his eyes gazed up to meet mine. I bit my bottom lip, not wanting to acknowledge how his touch sent tingles up my arm and throughout my whole nervous system.

"You ready?" He asked, just making sure I am confident about this.

"Yeah, I'm ready." I replied.

"Very well." He pulled me gently to his bed. He had set up a comfy pillow and warm blanket for us. He let go of my hand and sat down on the bed before patting his lap, gesturing me to sit on him. I slowly walked over and carefully climb onto his lap, my legs straddling on his thighs.

"You nervous?" He asked suddenly when he noticed as I was shaking against him making him feel worried.

"N-No Sans, I'm okay, just a little... surprise how we're in something like this." I replied quietly.

"Don't worry, it's actually my first time to be like this." He whispered softly, "Besides, it all comes to this, just one night for both of us." I heard a sigh from him and felt his arms wrapped around me to hold me close to him, I'm guessing he was nervous too. I gave him a hug just to comfort him so we can relax so we can start this. It only took a few minutes until he let out a sigh and loosen his hold. I darted my eyes to look up at him, his half-lidded eyes that held the little hearts and a dark blue blush was glowing on his face. He moved one of his hands up to placed over my cheek and caress it softly.

"Frisk, you look so beautiful tonight." He murmured, as his eyes began to wander, admiring my beautiful figure "Your body... it is so nice and soft~" He stroked his hands over my body sending electrifying touches on my skin and I shivered in delight. "Oh, how I love it so much~" I was blushing like hell, those words he spoke actually made my heart scream on the inside. I can't help by feeling the gentle touches he made, looks like he doesn't want to take things rough. I felt his hands trailed up to cup my face making my eyes locked onto his. We stared at each other for a moment before leaning in and began kissing passionately. His glowing blue eye was replaced in his left eyesocket with the wisp coming out, making him activate his magic. I wrapped my arms around his neck and leaned into him with more. He hummed in response and slithered his blue tongue out to lick my soft lips to ask for access. I accept his invite and open my mouth for him, letting his tongue slip inside my wet cavern. I use my tongue to play around his for a wrestle of dominance. He, however; knew that I was going to lose and yet - I did. After making out, we broke off the kiss with a string of mixed saliva spilling out and stick to our lips.

"Frisky, are ya now?" He teased, panting.

"Yeah." I agreed, feeling a little breathless.

"Well Frisk, I welcome you to..." He whispered and leaned over to my ear, "The Bone-Zone."

"This is your special place?" I questioned.

"Yep, and in here, you alone with me; I'll get what I want for: your body, your passion, your love and... your lust~" He explained, playing around a bit of my hair around his finger. "Believe me or not, I taught you everything from last night... Now's the time to put it into the test. For instant, I won't listen to you and you can't force me to stop. I'll keep going until you reached your climax, known to become 'one' love. Understand?"

I was starting to feel more nervous now. Having a lust-filled skeleton going over me without having him to listen or stop sounds like a hard challenge. But since I learn something from him, it's now or never... I placed my hand over his cheek and smiled.

"Alright, but be gentle okay? And..." I whispered and leaned over near his earhole, softly saying "bone me Sansy~"

I heard a chuckle from him and pulled back to meet his hungry look. "Yes ma'am." He started to kiss me roughly and lowered me down on the bed. He crawled over me with his teeth interlock with mine as he lay his body on top being careful not to squash me. He tasted every bit of my mouth as the kiss became heated. I cupped his face as I forced my tongue inside his mouth and his tongue came out to play with mine, we're both in heaven at this. He broke off with a string of blue saliva and went down to lick my neck. He ran his tongue over my skin which leaves a glowing blue saliva behind, and being careful with his sharp teeth because he really doesn't like leaving bite marks on me. I shivered in delight as he continued his activity, watching him as he did.

His hands wandered over to my chest until both of them felt my breasts. I gasped at the cold contact of his hands and shivered at his touch. He squeezed my breasts a bit and I moaned a little. "Your moans sounds really cute you know~" He commented, as he massage them gently. I was squirming underneath him, feeling his hands fondling with my breasts, sending excitable pleasure throughout my body with a bit of heat increased. He stopped playing and moved his hands behind my back and searched for the strap. He felt a piece of elastic at his fingertips and unhook it when he licked my collarbone. He pulled back to pull down the straps while feeling my smooth skin until it was off my chest, exposing my breasts to him. He was staring at me in awe.

"Wow, you look so damn sexy~" He complimented, while covering his mouth and his face was in blushing blue mess. "Holy shit~"

"Thank you..." I replied shyly, looking away from flattery and blushing very hard. Sans placed his hand over my cheek and turned me back to face him.

"Really Frisk, I mean it." He added, eyeing on them, "Would you mind if I could... taste them?"

"Go for it, if this is... what you want." I looked away in embarrassment.

"Okay." He lowered his face to my chest and licks my left breast. I let out a soft moan as he ran his tongue over the nub and flicked it around until it became harden. "A-Ahh!" I gasped, arching my back as he took the nub into his mouth and sucking on it while gently fondles with the other one. "S-Sans! Ah!~" I let out moans and gasps to him, showing him that I was enjoying this. He lets go and shifts onto the other one, repeating the actions again. I was squirming and wiggling underneath him, unable to control my body to handle the strong pleasure, he was pleasuring so much.

"Heh, your breasts tasted pretty good~" Sans commented, letting go the nub leaving his saliva behind and smirked at me. "But... how good will you taste from... down there?" My face went from red to crimson as I felt his hand trailed down to my underwear and rubbed his fingers against the wet spot in between my legs. He chuckled at my reactions as he continued, "I'll take that as a 'yes'." He moved his body lower and licked downward to my tummy leaving behind a trail of glowing blue saliva. He nuzzled against my abdomen as he latched his fingers onto my underwear. He was about to pull it down, but he shifted his eyesockets up to me to make sure this was still what I wanted.

"Please Sans..." I begged, using my puppy eyes on my adorable face to show myself so needy as possible.

"Hehehe, jeez you're so adorable~" He chuckled, as he pulled down my underwear slowly with his fingers grazing on my legs. He gently kissed and touched my hipbones as they became exposed. Sans wanted me to practically be begging for it by the time he was done. Finally he pulled off my panties leaving my body completely naked below him. "Holy shit, look at you~ You're so wet~" Sans eyed my entire body hungrily before lowering himself back down, he didn't move right in, oh no, he wanted to tease me a bit more. He grabbed my leg and kissed all the way from my knee down my thigh, just when I thought he was about to do it he kissed my other thigh. I was too revved up, I needed him.

"Oh, Sans please!" I pleaded desperately.

Sans smiled and looked up at me and chuckled, "That is exactly what I wanted to hear!"

"Wait, why?"

"I was just teasing you to see how much you want me right now." He explained with a smirk. "And since you beg so much, I'll give it to ya." He gave me a wink as he got onto his knees on the floor at the edge of the bed with his face in between my thighs. "Alrighty, let's see what you taste like?"

He started very slowly, appreciating me and my body. He used his tongue to lick my womanhood from its entrance up to my clit. He began moving his tongue freely from the inside and out. He drew the parted lips into his mouth and massaged them with his tongue. The sensations were driving me crazy, my body was reacting to his every lick and touch. He had to place his hands on my hips so I wouldn't move around too much. Once my body finally settled down, Sans slid one hand from my hip to my entrance and spread it apart, he then flexed his tongue and began to lightly circle on my clit.

I was now as hot as a Pyrope at a high temperature, he gave my clit quick little sucks by taking it into his mouth and gently sucking on it while he flicked his tongue over and around it. I feel myself getting hotter and wetter by the second he knew I was ready for more. "You taste so good..." He murmured, continuing to eat me out and brought his hand lower to thrust his index finger in my soaking wet womanhood. My body start to thrash and wiggled around from every lick, flick, suck and thrust, I can't handle this much pleasure. He want me to send overboard so he pressed another finger in with his first one and started doing a scissor movement.

My breathing started getting heavy, and my body was writhing in pleasure that I can't control. I felt a tight knot inside of me, making me lose into a pure bliss, I want to release my first orgasm. He pointed his two fingers inside of me upward to find my g-spot. I felt tingled and propped my body up quickly on my elbows and let out "ahh... S-Sans!" I saw his face reacted when I let out moan, it's a sign to show he found something to please me more. He began to rub it gently on the spot and kept in rhythm with his tongue on my clit. My breathing got heavier and the knot inside of me suddenly snapped as Sans gradually went faster and harder, making my organism rushed through my body and I screamed in bliss, squirting in his waiting mouth.

I collapsed on the bed panting heavily as Sans stood up from his kneeling position, licked his teeth and put the sticky fingers in his mouth, tasting me while I lay there watching him. I heard him hummed in delight, "Mmmm... you got some pretty sweet nectar there, Frisky~"

I blushed deeply and smiled at him, completely flattered by him, "Thanks..."

He crawled back over and kissed my lips softly before pulling back. "It's your turn now." He picked me up and switched places with me. He leaned his back against the wall with me on top.

"Okay." I trailed my eyes over him for a moment to figure out where to start. I don't know, there's so way to begin with that I can't choose, maybe starting with something simple. I kissed his forehead for starters and then raised both of my hands to his collarbone and peeled his hoodie. Once his hoodie came off, I placed my hands firmly against his chest, feeling his ribcage. I let out sigh of defeat and withdrawn from him, "Sorry Sans, but I don't know where to start."

"Oh, well... d-don't worry, I'll show you..." He took hold of my hands gently, "Just... touch here." He guided my hands over to his pants, "Then do like this..." He pressed onto my hands and I could feel his pelvis bone through his shorts. He dragged my hands across making my hands caress over his pelvis making him sigh, "That's it..." He gave me a grin before removing his hands so I can continue to stroke his bones, "Heh, see? You're a natural..." He chuckled and moaned when I trailed my hands over to the gap between his legs and he gasped. That was when I saw a faint blue glow appearing in his pants. I gasped quietly and shifted my eyes to him.

"What is that?" I asked shyly, making me sound almost like Alphys.

"Huh? You... don't know?" He questioned, scratching his head nervously "Well, it's... kind of obviously. But... I can show it to you, if you want."

"Uhh... C-can you r-remove t-them for me?"

"Sure, here." He grabbed the elastic of his shorts, lift his bottom up a bit and pulled his shorts down to expose a blue magic boner. I blushed at the sight of it and covered my red flushed face. This makes Sans look surprised at my reaction, and took hold of it with one hand and used his other hand to pull me over.

"Oh my god..." I murmured, eyeing on the blue magic glow; nearly drool a bit.

"I'm guessing you like what you see now~" He assured, as he placed my hand over his boner, "Now, do the way that I did to you."

I gulped nervously and slowly wrapped my fingers around it, feeling the texture. Due to his magic, it was stiff, hard and feels like touching cold jelly. I stroked my hand up and then down making a mental movement, "Mmh... hnn... Nnh~!" I'm starting to hear him moaning when I do this and looked at his expression. The heart pupils were quivering with lust and the blush was ocean blue.

"You... don't need my help, huh?" He asked, panting a bit.

I shook my head at him and I decided to try something to please him, I was curious - what does it taste like? I stuck out my tongue and place it at the bottom and gave a long lick all the way to the tip. "O-Oh yeah, just like that~" He moaned. I looked back at him and repeat it again before giving a few licks on the tip. "H-Hey Frisk, no need to tease like that~" He complained, playfully. I giggled a bit and placed my mouth over the tip, gently sucking and swirling my tongue around.

Sans was so in heaven; he pulled my hair back, out of my face to stared down at me. My glossy brown eyes shifted up to his face, he knew he would never see anything sexier in his life. He watched me closely as I bobbed my head up and down and my mouth took more of him in. "Ngh... mmh... h-hah~" I heard him gasp a bit and let out a chuckle when I stopped to look at him, "Heheheh, it uh - feels better when you do it."

I gave him a playful stern look and suck on his boner a bit harder, "Oh, fffuc-" He lay back on the bed with his mouth hanging open when a strong pleasure was inserted within him, making him letting out gasps and heavy breathing. "A-Ahh..." I stroked my tongue along with my drool sweeping down his boner. He was panting heavily and huffing each time I was about to do it faster, making him slicker. "H-hah.. A-ah!~~ Frisk..~ O-oh fuck~" He covered his mouth to hold back his moans and his curse words. He was about to release his first organsm so I quickened the pace and deep throated it, making Sans gasp loudly. "F-Frisk... I-I'm gonna... O-Oh god- Pull it out!" He warned me but I didn't stop so he pushed my face out as blue liquid suddenly shot out from the tip, splattering on my face a bit. He groaned and arch his back, more coming out now landing on my chest. He collapsed on the bed panting heavily from his bliss. He looked at me and saw the blue mess he made. "Aww... c'mere Frisk." He commanded as I crawled over to him and he licks the liquid of my face and chest. He wipe some on his finger and held up to my lips. "Here, say 'ah'." I opened my mouth and he stick his finger in my mouth, letting me taste his liquid. It taste a bit like ketchup due to his magic of making a substance. He took his finger out and smirked.

"We got one last thing to do..." He announced, getting up from his bed and walked to the drawer. He opened up and took out a small package. He rip it open and took out a small rubber material. He place it over the tip of his boner and pulled the elastic material down so it covers it all.

"What's that?" I asked, looking at the material he put on.

"It's a condom, it's protection so I can't you pregnant at a young age." He replied, walking back to the bed. "But since you're older, you're ready..." He placed his hands under my thighs and parted my legs a bit wider to position himself in. I looked down and gasped, his boner was rubbing against my wet entrance. "Okay, tell me when you're ready?" I blushed and nodded in response.

"S-Sans... J-just remember t-this is my first time, alright?" I bleated, "So be gentle with me..."

"Alright, brace yourself..." He murmured as I nodded in respond to him. He gently pushed the tip into me, and taking a deep breath to push in further more halfway and grunted. "Shit... you're pretty tight..." I gasped loudly and moan after, shutting my eyes with my hands gripping on his shirt. "You okay? Does it hurt?" He asked in concern. But I shook my head to him, telling him it's okay and keep going. He grinned and pushed in more until his boner was inside of me. I clenched my teeth and whimpered a little to stop my moans from escaping. We have to wait for a moment until the pain faded away from me. He pulled back to meet my face and kissed my forehead to comfort me. "Okay... I'll go slow first." He pulled his boner out from me before pushing back in a thrust, making it as gentle as possible. I sighed and loosen up my grip to let go of his shirt, so I wouldn't have to hurt him. I mewled into a sound of enjoyment instead of pain - I was getting the use of it now.

It took a couple of thrusts, until I beg for him to go a little bit fast. "Go faster? Sure thing Frisk." He grinned once again and does what I tell him to do. He put my legs behind his back and gripped onto my waist to hold my position. I gave him the lustful eyes of need, wanting him so much. He bend down and kissed me before thrusting into me a bit faster. I moaned a bit louder and Sans decided not to listen to me since he went on at half speed of thrusting. I moaned more, panted more and gasped more. He keep on going until he went a bit deeper and scream out and moan louder.

"S-Sans!!! P-Please hit it right there~" I begged through my sounds of intimacy. He didn't quite catch that but I continue to cried out his name and begged him again - that got his attention. He shifted a bit and pound into me faster. My eyes locked with his again with more lust filling inside and my tongue sticks out like a dog. He was smiling at the pleasure I was feeling right now. He began to thrust inside me in maximum speed, making me widen my eyes and scream out more.

"S-say my name Frisky, i-if you want more~" He told me, grunting. I spilled my screams out to shout his name, making his crotch harder and faster as he go. Sweat was pouring out of his skull, and pleasure still fills his bones. As he thrust inside me deeply, I arches my back and grips on the bedsheets harder. I saw the expression on his face that kinda reads 'Shit, I'm so close to coming.'

Sans stopped thrusting and pulled out his boner from me, making me whimper in disappointment and his absence. "Hang on... let me change into something..." He lifted my paralyzed body up and changed into a different position. He put me on fours like a dog, and went behind me - he wants do this in a doggy style. He pushed himself back in again and started to thrust again. He pounded into me so much harder that makes me arch my back up more along with my gasping, puffing, and moaning. I was in so much bliss that my energy was slowly draining from me, making me slipped forward with my head on the blankets and my bottom high up for him.

"F-frisk... I-I can't hold it in... I'm going to lose it." He told me, and I gasped. I don't want to get pregnant right now, I'm too young to have kids yet - let's hope this 'condom' actually works. After a few more powerful thrusts, Sans hunched over onto my back and let out a 'Hrrggg-' and gripped onto me as I let out a cry of pleasure when we reached our climax. We both collapsed on the bed, panting heavily. Sans pulled himself out and rolled down next to me. He looked down and pulled off the semi-filled condom from his boner and used his magic to send it to the trashcan. (A/N: Let's hope Papyrus doesn't find it! XD)

I lifted my head up, panting heavily and smile at him. "T-that... was... amazing..." I whispered. He chuckled and scooted closer to me and kissed my forehead.

"Yep, I knew we would have a good time." He winked at me.

"Oh, stop it..." I mumbled, playfully rubbing his skull like he did when he ruffled my hair.

Sans used his magic to lift both of us in the air, move the blanket above us and when the magic wears off, we fall back down and the blanket covered us. I snuggled into his shirt, and he cuddles like a teddy bear. We looked at each other with the tired passionate look. He lazily moved his hand to brush away the hair away from my face and smiled.

"Goodnight Sansy~" I whispered, caressing his cheekbone.

"Goodnight, Frisky~" He replied, kissing my forehead and cheek, "I love you~"

"I love you too Sans."

We cuddled together and soon we're drifted off into a peaceful slumber.
