------To the Bedroom!-----
Part 2

Sans had been in his room for the past hour or so looking stuff up on the monster web and the internet to try to understand what he asked of you and try to understand why you were so embarrassed.

He saw many things that got his attention. Woman on their backs being railed over and over by a man so much bigger and he had lots of muscle. He found it intriguing thinking to himself, "Would (Y/n) be making those noises? Would I be making those noises?" They were very strange to him to begin with.

He felt his body break out into a warmth. His nether region beginning to become uncomfortable for him. He pulled at the collar of his battle body trying his best to get some cooling affect to it.

He tried doing the same with his shorts but noticed how his magic was causing his appendage to become hard and uncomfortable. He never liked that thing due to his heat. He was embarrassed every year it happens. He wasn't able to understand it until now. His brother kept him out of the loop and he didn't like it. He likes being able to understand what's happening especially if it had to do with him or his brother.

He felt the heat start to kick in and he let out a low whimper as the effects were slowly taking over. He looked into everything he possibly could get his hands on. He wasn't sure how to approach you about it but he decided to just be straight forward about it.

He finally left his room after some time. He stood in front of you grabbing your attention. He grabbed your hands, you noticing how warm and sweaty they felt. You grimace slightly but keep your eyes on him waiting for him to speak. Instead he shows you.

He takes one of your hands and puts it down onto his hardened member watching your face for any difference, as if you were uncomfortable or disappointed with the current situation he was forcing you into.

You didn't mind you were flattered. You grin and flip Sans to be under you. He tried to get up but you pinned him beneath you. His hands held above his head by your very own slender hands. You looked good above him and he whimpered a little more at how angelic you looked. Your hair hanging around your head, framing your face.

You try your best not to tease Sans because you both were really vulnerable in this situation. You sat up and sat on your knees. "So Baby Blue what did you find? You're so eager to get into it huh?" He blushed hard at the questions knowing his answer which was yes. He sat up as well and quietly asked, "Do you make those noises too? Is that what really happens? That's what my appendage does?"

You lightly chuckle and explain, "Yes I could make noises, especially if you're pleasuring me well. Some of those things you may have seen do happen but not everyone likes the same thing, some people are different. For example, I like it when we take things slow and explore our interests. I also like it when you take your and my pleasure into consideration whilst doing the deed. And yes, that's what a dick does, and many other useful things." You both were blushing hard for different reasons.

You decided to play around and see how far things would go. So you pick up the small skeleton and say, "we're gonna take this to your room okay? Or would rather it be my room? It'll be nice and private and your brother won't bother us." He nods and points towards the room to the right, that being your room. The walk up to the room felt like forever, Sans was becoming impatient. He wanted to touch you, get his hands all over you, see what makes you feel the way he's seen. He wants to be the reason you make those cute, sexy noises. He's never felt this way for someone, he never knew he could feel this way.

The indecent thoughts were getting worse. You could tell since he was looking off in a dazed trance. You sit down with him in your lap. "Baby Blue... Baby Blue, Sans. Hi, whatchu thinking about?" You start to undress by taking your hoodie off and then your shirt leaving you in a bra and your pants. He blushed harder if that's possible. "So what would you like to do?" You start to trail kisses down his collar bone back up to his cheek bone. He shivered melting into your warm embrace.

He didn't intentionally do it, it just happened. He bit into your shoulder causing you to lightly moan causing said skeleton to shiver and look at you. He saw the pure pleasure from the look on your face. You sigh and decide that it's time to take things up a notch.

You decide to look Sans in the eyes and trail your gaze down to his teeth. You graze his chin and bring his skeletal lips to your soft, plump ones. Kissing him felt amazing what was more amazing is that you didn't even have to insinuate you wanted him to open his mouth, he had it slightly parted anyway. You shoved your tongue into his mouth and heard a startled moan leave him.

You made out with him for a good minute before you decided to part for air. There was a thick string of your and his saliva connected to both of your lips. He was staring at you with yearning.

He needed you, he wanted you to do all those things he saw. Maybe not all of them but quite a few piqued his interest. Like him hitting it from the back and having your head shoved into the blankets basically screaming his name. Or where you're on your knees just sucking him off while he sits on the edge of the bed. But there's this other one he saw where you were on top of him, riding him while he laid down and just took what was happening while gripping those nice, thick, squishy, soft thighs.

He jumped on top of you demanding you of this, "(Y-y/n)! PLEASE, PLEASE, PLEASE LET'S DO SOMETHING. I NEED YOU REALLY, REALLY, REALLY BAD!" You pick him up from your lap laying him on the bed. You take your pants off finally revealing a matching panty and bra set of your (f/c). You saw his eye lights change from stars to big hearts in mere seconds. "If you really need me that bad Baby Blue, what would you like me to do for you? Or what would you like to do for me?"

He shivered thinking about every little thing. He just wanted you in general but he knew he needed to take those baby steps. Not only for him but you too. He knew he had to do what it takes to pleasure you but he wasn't sure he'd be able to do that seeming how this is his first time experiencing this with someone else.

You got his attention back when you started to take his shorts with his boxers off. He shivered from the cool air hitting his hardened member. "Haaaaah... What are you doing? "

You giggled and continued to explore his skeletal body with your small hands. With one hand you stroked his thick, big member. With the other hand you were stroking his sternum and ribs. He couldn't stop making noises. He was really sensitive. Everything in his being was trying his best to stay quiet because he didn't want to be too loud in case his brother walked in.

You stopped for a second, "A-aaaahhhh, please don't stop..." You chuckled and replied, "As much as I'd love to keep going I've gotta make sure the doors locked, Sweetie. I'll be right back." You made sure the door was locked and once you turned around you found Sans with his hand around his member aggressively pumping it.

You walk up to him unclipping your bra in the process. You drop it to the floor along with your panties as the small skeleton watched. He had sweat dripping down from his skull, and the rest of his body. You don't know when he decided to take his battle body off but he did.

You gently take his hand into yours and move it off of his member and pin it above his head along with the other one. You finally sit down but his member was right in front of you. "PLEASE DO SOMETHING, ANYTHING!" "Anything you say... Mmmmmm~" You then pick your hips up and slowly work your way down his shaft having it enter your wet hole. He moaned loudly along with you as you took him in. You finally sat fully down, you're unable to contain your noises. Whining you lay your head on Sans shoulder to catch your breath that had quickened when he entered.

Sans couldn't think straight at all. His mind blank and jumbled at the same time, mainly thinking about you and trying not to explode. That's what it felt like down there, he felt like he was about to explode. It was too much at once and he didn't know how to express it. You look up and look him over observing and feeling him. His breaths quick and heavy. His body tense, bones rattling slightly. He clenched his teeth together along with his eyes. His face covered in a neon blue blush. It was so fuckin sexy.

You finally sigh out, "are you okay Baby Blue?" He slowly nods and opens his eye holes. You see his eye lights dimmed and quivering. "I'm not sure how to say this but... it feels like I'm about to explode. Nmmmmm~" You chuckle and reply, "I can wait for you. Unless you want me to keep going? But I can get off and wait till your ready, whichever works for you Baby Blue." He swallows hard.

He couldn't make up his mind, it was racing tenfold with them battling each other. Every thought going against his desires. His desires winning in every aspect. He twitches inside of you and you squeak from the sudden movement. Even tho small you felt it. He looks at you and asks, "You felt that? How.... Can you do that again?" You blush wildly and try not to lose focus. You release his hands and put them on your hips. He grips on as you finally begin to move.

You bounce up and down loving the way he made you feel. You moan with every thrust made. He couldn't meet you so of course you enjoyed doing most of the work to help please him as you pleased your self.

"A-ahhhahhhh.... Mmmmmmm.... Fuck.!" Holy shit, your Baby Blue just swore. You found that quite intriguing, you wanted to find out what button to push to make more come out. He never swore in front of you and surely hadn't around anyone you know. He just seems so innocent. But not anymore.

You keep hopping feeling the knot begin to form in your abdomen. He too was close to exploding. "Wahhhh~ Why do I feel the need to explode? Ughhhhh, it's getting harder to hold on, Cherry! Fuck!"

You wanted to make him keep swearing, it was about to set you off. You needed him to do it again in order for you to cum. It just triggered something in you every time.

He didn't know how much longer he could stop himself. It was becoming too much. Too much pleasure all at once. Too much of your stunning body, too much of you all at once. He keeps trying his best to hold on but he knew he wouldn't be able to any longer if you kept up the pace.

"God! Damnit! Fuck! Cherry please! I'm- I'm gonna explode. Ahhhhhhhh!" There it was the trigger for your release. You moaned out and came all over his ecto-plasmic cock. Despite his warning he came too, inside of you. You both ride out your orgasms staring at each other's pleasure filled faces.

"I said I was gonna explode, why didn't you stop?" You blush hardcore after that and look down and play with his ribs for a bit while saying, "you swore..." He didn't quite catch what you said so he asked you to repeat yourself. "Uhmmmm... You swore. I've never heard you swear before." He chuckles and responds, "well swearing is inappropriate. I don't normally like doing it but I guess I kinda just forgot about being... Modest." He blushes slightly, head tilting to the side outta embarrassment.

You slowly get up feeling him leave your hole causing you to quietly moan. He groans clenching his teeth slightly. He watched as his and your mixed cum drips down the inside of your thighs. He wants to keep going. He's never experienced anything like this before. He hopes asking you to keep going or if y'all can do this again is okay.

"Hey, Cherry?... Could we keep going?" You looked at him shocked seeing he was still hard even tho he did cum quite a bit. You thought about it for a bit and just shrugged, "I don't see why not. So... Yea let's do it some more if you'd like just give me some time to get ready. I'm a little tired." He nods and waits for you to come back.

You come back a few minutes later. You were cleaned up down there and had a glasses of water for the both of you. "Here, drink this. Your probably thirsty." He chuckles and takes the glass from your hands downing it in one go. He gets up and places the glass on the nightstand. He grabs your waist then proceeds to bring his hand up to the back of your head and quickly pushes your head into the bed. You were bent over the bed, ass in the air ready for him and you side eyeing him embarrassed that he took control. "Are you okay? Is it okay for me to do this?" You say yes and he proceeds to give himself a few pumps before slowly sticking it in.

"Shit! You feel so good... Mmmmm" He rocks his hips back and forth into you keeping a hand on your hand and his arm wrapped around your waist keeping you up. He kept pounding into you enjoying the noises you were making, all because of him. He never dreamed that he'd ever do this especially with you. He just wanted this to last forever but he knows that it can't always happen. He knows that this is a special ritual for humans.

You were enjoying every bit of the fucking you were receiving. He was dominating you and you'd never thought a day in your life he'd be able to take charge like this. At first you enjoyed him as a little submissive skelly under you but you're not sure which you like better in bed. His new dominating daddy side or his baby submissive side. Either way you were just glad he gets to enjoy himself. "Fuck... Cherry, you feel amazing. You're beautiful. I can't get enough!"  You were too brain fucked to even respond. All you could do was moan over and over. He was hitting all the right places, and you were going to cum once again.

He felt you. You were clenching down on him again. He knew you were close and so was he. He didn't want to be done but you looked like you were gonna pass out. It felt amazing to him and you. He was glad it was with you. He was glad that you told him what he didn't know. He now knows and wants to keep doing this hopefully more with you.

You both came and he pulled out this time cleaning the both of you up. Laying you down and tucking you in with him beside you. He scoops you up into his arms and lays you on his chest running his phalanges through your (h/l) (h/c). He whispered 'I love you's and a bunch of compliments into your ear as you both slipped into slumber.
