—
Sandwiched between Susie and Kris, you stared at the scene before you three in absolute shock…and confusion. Music blaring, wine swishing around in a glass, Toriel and Sans seemingly dancing the night away…it was a lot to take in.
You turned your head to look at Kris, feeling some concern forming. They turned their head, so you couldn’t gauge their reaction… but you had a feeling that this wasn’t the most comfortable thing for them to walk in on. You were so distracted, trying to figure out what to say or do, that you didn’t really pay a whole lot of attention to whatever the others were saying…until Susie ended up leaving. That’s when you finally looked over and fidgeted. Should you leave too or—
“-Then will you be staying, sweetie?” Toriel asked.
Part of you felt maybe you shouldn’t. Things were just so…so awkward now. But one glance at Kris next to you and you felt something else tug at your chest. You…didn’t feel right just leaving them alone.
“If that’s okay.“
“Perfect! Then you can use Asriel’s bed instead.” Toriel said joyfully.
You blushed.
“His b-bed-“ you stuttered a bit.
“Of course! And you can borrow some of his old PJs too! Go ahead, dear; they should be in his bottom drawer.”
You look over to Kris again, then back at Toriel. “Alright…thank you.” You go to follow Kris inside, all the way straight to the bedroom. Once inside, you stared, perhaps a bit too long.
You’d known the Dreemurrs since you were younger. You’d been friends since childhood…at least you always considered yourself a friend. Though you did always have a little crush on Asriel. Even after he left for college, you could never seem to shake off this little crush…even after all these years.
You looked over to Kris, who sat at the edge of their bed. “Are…uh…you going to shower first?” You asked awkwardly, with a small smile as you tried to keep things positive. At least as positive as you could. At Kris’ head shake, you turned to grab the PJs from the drawer, shyly carrying them in your arms. “Alright, then I’ll go ahead… I’ll be quick.” You said before you exited the room. You knew your way around, so you went straight to the bathroom to shower.
You had been looking forward to showering in general, after everything that happened today. You really needed to feel that hot stream of water loosening the tension in your shoulders and washing away all the sweat and dirt…
By the time you stepped out of your shower, you were far more relaxed. You picked up the button up top of Asriel’s old PJs. They were so soft. Shyly you brought it up to your nose and inhaled. Fresh laundry, and that hint of something sweet. That scent you’ve always associated with Asriel. Your cheeks heated up at your own actions, a bit embarrassed. You were being such a creep…
You quickly slipped the PJs on, folding up the pant legs a bit; otherwise, they would drag on the floor. Asriel always was taller. Once you finished up, you left and made your way right back to the room, watching as Kris got up to take their turn in the shower. Once alone, you stood in front of the bed. Asriel’s bed. You gulped as you slid your hand over the covers. It had been a long time since you had been here. You bit your lip as you crawled onto the bed, getting under the covers. Surrounded now by that sweet soft scent again, it was almost like he had never left. Like he was still here…
You had wanted to stay up and wait for Kris, maybe try to talk to them a little. See if you can cheer them up and make sure they’re okay.
But the bed was so soft, it was so warm, and…it smelled so comforting. Before you knew it, you ended up falling asleep. You were a lot more exhausted than you realized.
—
Kris let out a shaky breath as they stood in the shower. A hand was placed flat against the tiled wall, while the other gripped at their chest.
You’d think they were bothered by what they walked in on. By their mother doing…whatever all that was. Whatever dancing she was doing with Sans.
But they could hardly think about that.
All they could think about was…the way you blushed.
You have always done that. At the mere mention of Asriel, you were always blushing and stuttering. They knew all about the crush you had on their brother. You didn’t hide it well at all, though their brother was too oblivious to notice anything anyways.
They hated it.
It always grated on their nerves, inexplicably.
Well, maybe not entirely inexplicably. They hated the way the two of you always seemed so close. The way you’d come up with games to play between just the two of you. The way you’d laugh at anything Asriel did or said. The way you kept only ever looking at him. But he wasn’t here. He wasn’t.
So why couldn’t you look at them instead?
Why couldn’t you smile and laugh with them the way you did with Asriel?
Before the first dark world, Kris hadn’t seen you smile in…a long time.
They always had these feelings they could never fully explain. They felt this…extremely violent impulse every time they so much as thought about it. About you…and Asriel…and your feelings for him.
It was this obsession that they had tried so hard to push down and pretend didn’t exist. But you made it so hard… Just being around you drove them crazy. Just being around you made them want to reach out and touch your hand. For no real reason. Just to feel it. But every time Asriel comes up, your reaction is like a slap in the face. A plummet straight back into the reality that your heart…your soul…only seemed to want their brother.
Not them.
Shutting off the water, they stepped out. They walked up to the mirror and stared at their reflection for a long moment.
They needed to get it together.
If you knew… If you found out what they really thought…
What they really wanted…
They shook their head and went to get dressed.
—
Walking back into their room, they paused at the sight of you already tucked in and snoring softly.
Their hand clenched.
Their chest hurt. So they got rid of the problem. With a pained groan and gripping at their chest, they violently ripped the source right out. They panted as they held it in their hand, gripping it tightly so it couldn't escape. They stumbled over to the corner of their room and tossed it in its cage. They glanced at you over their shoulder. You were always a deep sleeper. All you did was turn away slightly. But other than that, no stirring. Good.
With a soft sigh, they lay on their bed and just tried to go to sleep.
But they could hear the sound of the music playing.
The way their mother laughed as Sans told another joke.
Kris tossed, trying to block out the noise with their pillow.
They tossed and turned, over and over and over, and just…it was all becoming too much.
But then they heard it. A soft whisper from the other side of the room. A barely comprehensible mumble… one that sounded like you said—
They couldn’t take it anymore.
They just couldn’t stand it.
They got up, tossing off the blanket, and made their way to the bed you were currently obliviously sleeping in. They stood over your form, hunched at the side, and just watched you.
In his bed. In his clothes. It made them sick.
They carefully crawled onto the bed until they were straddling you, not putting their full weight to avoid waking you up. They then gently eased you onto your back and pushed the blanket down to your waist. You really were such a deep sleeper. They wondered how far they could go before you noticed anything…
The temptation was too irresistible…And they had wanted this for so, so long…They slowly unbuttoned the front of their brother’s PJs, exposing your torso. The cold air made you jolt very slightly, but nothing more. You were fully exposed to them now, for their eyes only. They slowly slid a hand over your soft stomach, all the way up to your chest. Their fingers lightly grazed a nipple, and they watched how you inhaled such a small gasp in response. They repeated the action again, wanting to hear it more. Those sounds were for them. Made because of them. They suddenly gave your nipple a pinch, causing a squeak to slip out of you.
The sound made them pause. They needed to hear what other sounds they could get out of you. So they dipped their head down and slid their tongue over your nipple. They used their hand to pinch at and tease the other one, stimulating both now. You were so sensitive; they could feel you trembling beneath them. Even in your sleep, you were so responsive. It just made Kris want to bully you some more. So they continue to grope and prod and lick, even bite. They were completely lost in your reactions, the way your body shook beneath them, arched up when they bit you, squirmed when they pinched. But then—
“Asri…el…”
It was such a quiet whisper, so quiet that Kris might have missed it had they been more distracted. But no, they heard it. And it enraged them. Again.
They paused and sat up, looking down at you. Did you think all this pleasure you were feeling was from their brother? Did you have the audacity to dream about him?
Fine.
Then that just meant Kris was going to have to go a lot further to show you that it was them making you feel good. Making you blush. Making you—
They slid their hand down slowly, right under the waistbands of the pajama pants, and slithered right between your thighs. They groped your crotch over your underwear, testing and feeling.
It’s as they thought. You were absolutely turned on. So turned on, there was a bit of a moist patch forming on the fabric of your underwear.
That was all them. That was all for them. You’d see. You were smart. You would figure it out and finally see them.
Kris hunched over you, leaning real close to your face, red eyes piercing through the curtain of brown hair as they intently watched your face. They wanted to see every twitch, every expression, and watch your lips part with every gasp and moan from what they were about to do next…
They slipped their hand beneath your underwear this time, sliding it deep in until they reached exactly where they wanted to torment you. Their fingers slid right to your entrance, grazing it a few times at first, watching the slight furrow in your brow that seemed to form. They licked their lips as they slid a finger into you, slowly, taking their time to really feel how you tightly wrapped around one mere finger. How your lips parted as you gasped sharply. And yet you still didn’t wake up. They wondered how you’d react if you made a mess in Asriel’s PJs. If you stained them so bad…all thanks to Asriel’s little sibling. Would you be ashamed of it? Would it embarrass you? Make you cry?
Those thoughts alone had Kris eagerly thrusting their finger inside you, feeling your body tense up against theirs. Watching your face scrunch up into one of confused pleasure. You were always so pretty when you were confused. Did this thing with the corner of your lip. It always made Kris want to bite it. Something they would usually dismiss as an intrusive thought. But, seeing as tonight they were already giving into their urges…
They closed the admittedly small gap between your faces, at first pressing their lips softly over the side of yours. Then, sinking their teeth into your bottom lip. Kris let out a shaky groan the second they could taste you. It was intoxicating. The things you did to them, and you didn’t even know it. They slid their tongue over your now slightly swollen lip, sitting up a bit as they pulled over a certain item of theirs.
They weighed the handle of their favorite knife in their hand, looking at it, the reflection of their eyes in the clean metal staring back at them. Then they looked at you. Another urge they would usually try to dismiss. They slid the flat surface of the knife along your torso, up the center of your chest, grazing your nipple with the dull side. All the while Kris hadn't stopped fucking you with their finger. They could feel how you tightened up from what they were doing. So they slid a second finger into you, stretching you out even more. Your body involuntarily arched up at the feeling. Kris hadn’t expected such an intense response, so the sharp edge of their knife lightly nicked the skin right over your ribs. A thin line, about an inch and a half…it began to seep blood. It was a clean cut, but not too deep. Just enough to bleed.
The sight of it made Kris absolutely lose it. They dropped their head down and began to shamelessly lap at it, greedily licking your precious blood while mercilessly speeding up the fingers they thrust into you. They may have been going a little too hard on you, because now you were a moaning mess. As Kris glanced up at you, they saw the exact moment your eyes blearily blinked open, but not for long. You only woke for a second before suddenly your entire body was wracked with pleasure, your entrance twitching around Kris’ fingers as you came. It was too much for your body to take all at once, so as quickly as you were awake, you had just as quickly passed out. Barely having even been awake enough to process what was happening. Or who was doing it.Kris sat up, a bit of your blood staining their lips slightly. They pulled their fingers out, using them to also pick up all the cum that you had released. They stared down at it, at their filthy, dripping hand, before promptly licking it clean. When it came to you, they were a glutton.
But this wasn’t enough, as one would expect from a glutton. You hadn’t even acknowledged them for the split second you were conscious.
Now that just won’t do.
So, with that in mind, Kris slid down, slinking under the bedcovers. From the outside, it would almost look like you were innocently sleeping, bundled up with only your head exposed now and the blanket pulled up to your chin.
Kris slid all the way down until they were lying right between your legs, shielded by their brother’s thick blanket. They wanted to taste more of you. They needed to; it was insatiable. So why not go straight to the source?
—
You squirmed a bit, though mentally noted how you seemed to be stuck lying on your back. Your eyes felt so heavy, you could barely open them, so you kept them closed. Until your senses began to pick up on the world around you.
Something felt…heavy. On your hips. Like there was pressure on your sides, keeping you there. And there was something…something wet between…
Your eyes snapped open, gasping. Your face flushed as you panicked, not knowing what was going on.
“W-wha- AH~“ you stuttered, trying to speak, only for it to turn into a moan. You lifted the blanket up, eyes widening at the sight underneath.
The first thing you noticed was the red. Those piercing red eyes staring right back at you. Jarring but…familiar. And then you realized—
“Kris! Why are you—" you tensed up, unable to finish that sentence as Kris shoved their tongue deeper inside of you. “Kris, that’s… That’s dirty!” You tried to protest. You tried to reach down and push Kris’ head away. “Stop it…”
But hearing you say their name, their name finally…in that voice. So broken. So needy. It only spurred them on. No amount of pushing at their head seemed to work; they didn’t budge even an inch, only pressing their mouth against you harder as they slid their tongue around you and teased you.
You let out a much louder cry than you had when you were asleep when you felt that tongue thrust into your entrance so harshly. Kris wasn’t worried about being heard, though. The music playing in the living room was still too loud for anyone to possibly hear you over it. Which meant your voice was for their ears only. And no one would be interrupting you either.
“Kris…please…” You gasped; your pushing had turned into desperate gripping at their hair instead, trying to ground yourself somehow. But your mind was still groggy from sleep, and your body wasn’t listening to you either. You felt so hot all over, and the way Kris was making you feel…this involuntary pleasure sent overwhelming waves through you that had your back arching and your legs trembling.
And the way they were looking at you. They hadn’t stopped a single time, that piercing red gaze locked on you. It was so unsettling; you felt terror rush through you every time you dared to look. And yet…it only seemed to heat up your body even more. Did it…excite you? To be looked at like that? To be looked at by those eyes that you…hadn’t seen since—
The thought was interrupted when you felt it. That cold sharp blade against your stomach. You looked down, your eyes having been tearing up. You stilled completely, crisp fear overtaking you. What were they—
Kris pushed your legs up over their shoulders until you were practically folded over. Their tongue now able to reach even deeper inside you in this new position. Your face heated up more than it already was, feeling even more exposed like this. But you couldn’t protest. You couldn’t say anything, because every time you opened your mouth to try, a disgustingly desperate moan slipped out. And every time you tried to tug at their hair, that knife got closer and closer until it was pressed right against your neck.
You couldn’t take it. It was all too much. All it took were a few more licks and thrusts from Kris’ tongue, their hot mouth practically devouring you, the cold of the steel so close to cutting your entire throat wide open…
You came. Your orgasm was ripped out of you, taken despite any logic or reason or morality you tried to cling to. You shouldn’t be cumming. You shouldn't be feeling good. You should be disgusted, angry, or anything other than cumming so hard that your eyes were rolling back and drool covered your chin.
You couldn’t think. At some point, as your body twitched from the most intense orgasm you’d ever experienced, you completely lost consciousness again. You passed out and only let out a shaky, tired moan when Kris pulled away.
They looked over your fucked-out body, the mess you made all over the now soiled bedsheets. Something like pride or satisfaction formed within Kris at the sight. You, with your legs splayed out, twitching still. A mess of cum and saliva all over your thighs, soaking the sheets of their brother’s bed.
How would you feel if Asriel saw you now?
Out cold from an orgasm his little sibling gave you. only they could give you. They sat there, looming over you, bringing their knife up to inspect it.
They weren’t done just yet.
—
You flinched slightly as you opened your eyes the next morning, the sunlight from the window blinding you for a second. You felt so tired… Did you not sleep well?
Then you remembered. With a gasp, you sat up, looking over yourself.
The PJs were…exactly as they were before you went to bed. Buttoned up. Nothing askew. The sheets looked fine…everything seemed…normal.
A dream?
You hesitantly looked over to Kris’ bed, seeing they were still asleep. You bit your lip and blushed.
It must’ve been… just a really weird dream.You covered your face with your hands, embarrassment and shame settling over you. How could you have such a…vulgar dream about one of your best friends?! And…and why? Why in these circumstances? You…you liked Asriel. So why?
You were confused with yourself and your own subconscious. They say that people will sometimes dream of their deepest, most secret desires… Could you possibly…
You shook your head. No way. It was probably just a random dream, no explanation. Things like that happened. That’s all.
With a sigh, you decided to get out of bed and head to the bathroom. You needed to freshen up… A splash of cold water should help plenty.
As you stood in front of the bathroom sink, you splashed your face a few times and sighed. You felt a little better. You shifted to reach for the toothpaste, then winced.
Something kind of…stung? And itched? You quickly unbuttoned the shirt and furrowed your brows when you noticed what looked like a thin cut right over your rib…
You must have scratched yourself in your sleep or something… oh well.
You were quick to get dressed and ready, heading to the kitchen afterwards. You smiled at Toriel, greeting her, though she certainly seemed tired this morning. Probably from all that partying. You sat at the table, and a few minutes later Kris finally joined you.
You smiled at him but shyly shifted your gaze to the table, more interested in the smooth wood surface than making eye contact with them.
You couldn’t bring yourself to…
It felt too awkward… How could you even fathom looking at them after what your nasty mind conjured up?!
You jolted when they spoke to you, though, asking if you slept well.
“Oh…y-yeah I did.” You were lying through your teeth, but you couldn’t possibly tell them the truth. When Toriel kindly set your pancakes down in front of you, you were quick to dig in, using your fork to get a good piece with extra whipped cream. Maybe if you stuffed your face, it could help distract you.
Kris smiled slightly.
Then they reached out and took your wrist. Toriel’s back was facing the two of you as she was preparing Kris’ breakfast.
You paused, confused and curious as you braved looking at Kris.
“Huh? What is it?” You whispered nervously. Did you do something wrong?
Then, they brought your hand up to their face. They licked your palm, or rather the whipped cream you had accidentally gotten on it in your haste to eat all of it.
Your face went bright red, and you damn near combusted.
“K-Kris?!” You squeaked before slamming your other hand over your mouth. They let go of your wrist, and you quickly retracted it close to your chest, staring at him in shock.
They smiled at you, almost innocently. Claiming they were ‘just trying to help you, since you made such a mess.’
Somehow, those words only seemed to make your flustered expression worsen.
Yet you were sure that there was no way Kris could possibly know about your ‘dream.’ No. You were just being weird. That’s all. So you turned back to your plate and tried to just act normal again, smiling and making polite conversation with Toriel when she came back.
Kris watched you try so hard to act unbothered. To pretend you weren’t thinking about last night. It was cute… They just couldn’t resist teasing you.
They’ll let you believe whatever you want to believe. For now.
But this wasn’t nearly enough. They just had to be patient, and slowly you’ll see.
