Is this what heaven feels like?

Summary:

Oh no! Due to a strange spell, an amnesiac Dimitri is trapped in a weird dimension. Even stranger, a man and a woman both called Byleth are trapped with him. They both seem to know Dimitri, but not each other.

How are they going to escape this bizarre situation?
(Spoiler alert: They all bang)

A treat for mochipicchu776 for the Dimileth Valentine's Exchange 2026

Notes:

Can I offer you a Dimileth sandwich in these trying times as a little treat?

(See the end of the work for more notes.)

Work Text:

Sharp pain soared through his head. Dimitri opened his eyes. Urgh… my head. Where am I? I need to  ….do what? Arg, I don’t remember! No matter how long he broke his head over who was with him, he couldn’t remember what happened. Every muscle in his body ached, but his head hurted the most.

Welp, there was no way to keep sitting around here doing nothing. He took in his surroundings … or rather the lack of anything tangible. Around him was an endless void, stretching for as far as he could see. Dimitri began to run in one direction for what seemed like an eternity. Did he die and enter the afterlife? He would have imagined more flames and suffering. Yet he couldn’t hear the voices of the death haunting him. It was oddly quiet in his head for once. 

Suddenly, he saw a beautiful woman in the far distance, who looked about his age. She looked… familiar and yet he could not remember her name. Was she the one he was looking for? Or was she an enemy? 

Before he could ready his weapon, Dimitri and the woman locked eyes. Immediately her bored face lit up and she gave him a mesmerizing smile. Her heels clacked against the strange floor and she sprinted towards him. “Dimitri! Are you all right?” She laid one of her hands on his shoulder and inspected him, presumably looking for wounds.

She must be an ally, but he still couldn’t remember who she was. “You… know my name? Do I know you?” Dimitri blurted out. Her facial expression suddenly turned sad. She opened her mouth, but before she could say something, she raised her sword to block an incoming attack from above and pushed Dimitri out of harm’s way with her other hand.

The attacker was a pretty man, with the same shade of blueish green hair as the woman. Even his clothing style was oddly similar to hers. 

The man turned his attention towards Dimitri. “Look out, Dimitri!!! She might be an enemy.” He also seemed to know Dimitri’s name to his surprise. He had a feeling of familiarity with him, but just as with the woman, his name completely evaded his thoughts.

Just as he was coming closer, the woman jumped between them and pointed her sword at the man’s throat. “I will not let any harm happen to Dimitri, leave now or I will cut you down.”

“Heh, do you even know who you are challenging?” 

 “It seems you are out of your league. Prepare to die”

The man and the woman clashed their swords together in a mesmerising dance, accompanied by a song of the clanking blades and their master’s laboured breaths. Somehow they predicted each other's moves with a bizarre accuracy and even mirrored each other's stances. Sparks flew from where the blades grinded together. Both their eyes widened when they looked at their opponent’s swords. Immediately they jumped away from each other and looked back at their own blade.

“Huh? That sword... Where did you get that?!” They both said in perfect unison. The way the tone of their voice and inflictions were the same was really eerie, Dimitri noted.

She raised her sword to the man’s face, just inches from his nose. “I wanted to ask you the same thing. This sword was given to me by my father: Jeralt the Blade Breaker.”

“Impossible, I am Jeralt’s only child!” The man pushed her blade away from his face with his own, seemingly identical to hers. 

“What even is your name?”

“Byleth” Byleth what a stunning name… for a pretty man like him.

The woman looked extremely puzzled at hearing his name. “Curious… My name is also Byleth. What is the meaning of this? Are you messing with me?” 

“Maybe you are the one who is tricking me.” They once again pointed their blades at each other in perfect unison. 

Both of them circled around each other, reminiscent of what those wild cats in the camp did when they saw a new cat for the first time. Their eyes darted on each other’s form  up and down,and then from left to right, taking in each and every detail of their opponent. 

“We can’t both be Byleth. One of us is lying… and it isn’t me.” The woman cocked her head to the side.

He narrowed his eyes on the woman. “Neither am I lying.”

A pregnant pause fell over them. The whole void felt even more empty. The tension in the air was palpable. Neither of them even moved a muscle or made any kind of sound, lest not to spook the other one. Their wild, unblinking eyes just kept staring at each other, maintaining eye contact for an uncomfortable amount of time. Suddenly they both turned towards Dimitri. 

“Dimitri, tell them. You know me!!” They once again shouted at the same moment. This time it even startled them to the core.

The two ‘Byleths’ looked at him with their beautiful lavender eyes. Now that’s not a  remark to think about… a stranger? Hmm, maybe they aren’t strangers to him. Dimitri cleared his throat. “I-I don’t remember. My memories are hazy… I-I…” His eyes darted between both of them. If he didn’t know better, he would say they were siblings, maybe even twins. The woman sighed and the man pinched his nose. 

Now, now children. What is happening here? 

An ethereal voice chimed through the void. Behind that childish voice was a great amount of wisdom. 

“Sothis?” They both yelled

Byleth looked at his female counterpart. “Huh? You know her too?”

“Sothis, who is this? Why are they claiming to be me?!” 

You are both Byleth, albeit another form. You came from different universes. Very similar ones, from the look of it. You both were ambushed by those weird people, in the exact same scenario. 

With a bored look on his face, he looked up. “Now that is just silly, Sothis.” 

“Yeah!” The female Byleth said.

Urgh really? Why are you so stubborn? You know I would never lie to you, Byleth. 

“Okay, prove you are me,” he said with a monotone voice. “How many tabs has Jeralt currently open?”

“Easy, 234, not counting the ones he shares with the crew.” Byleth said confidently.

Byleth nodded in agreement. “Right…” This seemed to have satisfied him. 

“Now it is my turn. How many times has Jeralt told you a funny joke?” She said in the same, monotone voice. 

“That’s a trick question, he has never told me a joke that made me laugh. He is the most unfunny person in the camp.”

Both of them closed their eyes and laid their chin on their hand. It was mesmerising seeing the two Byleths fall in sync. So different, yet they were the same. Their beauty and handsomeness really did exceed time and space?

“Now, are you also wearing ‘your special underwear’ for him today? You know the one with the sheer black lace?” She elbowed her male counterpart. 

“Oh… you really are me. How else… nobody knows I…” He began to blush, avoiding Dimitri’s gaze. The female Byleth looked smugly, but the moment Dimitri looked at her, she began blushing as well with the same embarrassed expression.

Huh? Dimitri was confused. What did they mean by that? And who was the ‘him’ they were talking about? They seemed to have prepared some sort of surprise for that man. He suddenly felt extremely jealous of whoever they were doing this for.

“Euhm nice to meet you, Byleth?” She extended her hand towards her male counterpart.

He cautiously shook her hand “Nice to meet you too, Byleth?” Dimitri was happy the two of them were at least friendly now. 

Finally! No matter the form you take, you are such a hardhead. How dare you question MY word. Hmpf!!

“What is the last thing you did before… this?”

“Me and Dimitri were battling some strange people. One of those mages shot a strange spell at us and then… I woke up here.”

“Same!”

Dimitri was still looking in awe at the two Byleths. “It doesn’t ring a bell to me. I don’t even remember your name… not remember much.”

A weird spell… from strange people. And now you are all here. 

This certainly is a spell ‘they’ would use. 

But not exactly… something seems wrong. We might be able to use this to our advantage.

But if each of the Byleths came from their one universe, they must be… Dimitri thought. “So why is there only one Dimitri, but two Byleths? Or is there another one here we haven’t found?” He blurted out.

I can’t sense any other lifeforms in this dimension besides the three of you.

Now that you mention it, this is quite strange. I wonder …

Suddenly a young green haired girl materialised in front of Dimitri. Her clothes looked regal. Was this the goddess Sothis he heard so much about? This was not how he imagined her. He gave her a shy smile. “H-hello?”

This human can see me here? How curious! Let me have a closer look at you.

The weird girl came uncomfortably close to him, invading his personal space. Her hand phased right through his head. She closed her eyes, deep in thoughts. After a while, she floated back up and twirled around the Byleths in a playful way. 

Well well, he is both ‘your’ Dimitri. 

Somehow he merged into one? Probably because you all came from surprisingly similar universes.

What? How could he be… 2 versions of himself at the same time? Dimitri thought to himself. 

Hmm, he must be the key to your problem. Something that connects you… even beyond universes. 

There must be a way to split him up and return back to where you came from

Maybe even… some unspoken feelings?

They waved their hands at the teasing girl, looking like they were swatting an annoying fly away. “Okay Sothis, that’s enough. You don’t have to tease” They both sounded annoyed and embarrassed.

Dimitri, do you really not remember anything? 

“No, but I feel like I know them. That they are… precious to me. There was something I think I wanted to tell them, but I forgot.”

I think a connection can jog those memories so you all can sync up.

The deeper and the more intense the connection, the better I think

Just give it a try

Why don’t you all hold hands for a start?

“…” They all wordlessly each reached out one of their hands to him. Their fingers intertwined with his. Dimitri’s clumsy big hands looked awkward around the Byleths’ dainty fingers. So soft. Looking at both of them was so… mesmerising. Byleth really transcends beauty beyond every universe, whether it be male or female. Suddenly, some of what happened flashed before his eyes. “Ah, my memories are coming back” He blurted out

“So… what do you remember ?” They both looked at him with their big, lavender eyes. 

Dimitri took a deep breath. “Yeah.. I remember you now! I wanted to tell you something… but…”

“But?” One stare of those eyes was already enough, but double that amount made Dimitri immediately fold in half. 

“It's embarrassing… I… I think I like you, Byleth. You are just so mesmerizing and… amazing and… urgh. Sorry, I’m just blabbering now”

Both their faces turned red at his confession. “Dimitri… I… we like you too.” Dimitri looked back and forth between the two Byleths.

Urg, I really thought Dimitri confessing his feelings would stop the spell but it is not enough!

Maybe we need something… more physical for it to work.

The Byleths looked at each other. They whispered something to each other in hushed tones he couldn’t understand. And then Dimitri felt two pairs of plush lips kiss his cheeks from both sides.

“Oh!” The place began to shift and the void was no longer black, gaining more colours. Something was definitely happening now. “It’s working. We need an even deeper connection. Kiss me on the lips, Dimitri!” She said

“No, I want to be the first one to kiss Dimitri!” Dimitri felt him pulled to the other side. The Byleths gave each other a mean look. “Okay, together. Close your eyes, Dimitri”. He did as he was told and anxiously waited for what seemed like an eternity. Each corner of his lips met another pair of lips. Dimitri kept on kissing their lips, switching from one Byleth to the other one. While he was kissing one Byleth, the other one placed their lips all over his neck and face. Spit ran down his chin and theirs. It was messy, but nobody seemed to care. Two pairs of hands glided everywhere over Dimitri’s body. Oh how he wished he was not wearing so much armour.  

Ahem

Well, it is really nice to see you kids FINALLY be honest about your true feelings, you all really need to return to your own worlds as soon as you can. The longer Dimitri is like this, the harder it is for all of you to go back to your own universe.

Let me be very blunt: the fastest way for all of you to sync up requires something more… carnal

You all need to reach an orgasm, at the same time AND be deeply connected on a physical level 

Now, you are all old enough to know exactly what I mean.

I will now take my leave and give you some privacy

Have fun, Byleth

Dimitri swallowed. “How exactly are we going to do this… I have no real experience with this, especially not like this?” While Dimitri was still wallowing in his embarrassment and coming to terms that he has to make love to two Byleths… they already undressed themselves down to their underwear. The sight of them was indescribably arousing and mesmerising. They stepped closer to him, swaying their hips in a playful manner. Their lips moved closer to his ears, until he could hear their mesmerising voices whisper in his ears, sending shivers down his spine. 

“You look a bit overdressed, Dimitri”

“Yeah, Dimitri. You are always so formal. But no worries, we will help you.”

Their beautiful hands made quick work of his armour and clothes. Finally, their skins touched for real. 

“So Dimitri, do you like our underwear? I-we bought it for you. Can you tear it off now?” 

Without even thinking twice, he grabbed both their panties and shredded them to pieces in a frenzy. They both let out a surprised moan and this sight was too much for poor Dimitri’s brain. He shuddered and just came like that. Only from seeing both Byleths naked. How embarrassing and pathetic. “Sorry, I was overwhelmed by your combined beauty and radiance of your glorious bodies. I-”

“It’s all right.”

“Come on Byleth, let's get his dick back in working order.” Both of them kneeled in front of him, kissing their way down to his crotch. First they prepped kisses all along his thighs, while their hands got to work on his soft member. One of each of their hands was almost enough to envelop his manhood. As his member hardened, they began using their mouths on it. They each kissed and alternately sucked on his hardening member. In no time, he was rock hard again. Satisfied with their work, they retreated before Dimitri would cum again. It was time for the main event now.  

Byleth sat down and motioned Dimitri to sit on his lap. “Ready Dimitri? Just relax.” Byleth’s dick entered his asshole very slowly. Small tears prickled in the corners of Dimitri’s eyes. When they were finally flush with each other, the other Byleth climbed on top of his lap and lined Dimitri’s dick up with her slit. She was not as patient as her fellow Byleth and shoved herself on his rock hard member. “How are you feeling, Dimitri? Is everything still all right?”

There were no words to explain what Dimitri was feeling right now. Both of them, at the same time… Dimitri felt like he would combust any moment now. “A-ah, I-It feels a-amazing!” It was a bit awkward at first, but eventually the trio got into a slow but steady rhythm. Dimitri was completely blissed out now, unashamedly enjoying something for once in his life. Their lips sucked on either side of his neck nibbling softly on it. So many hands touched Dimitri all at once, completely overstimulating him. I don’t think heaven will ever feel half as good as I am feeling right now. Loud moans and groans filled the whole dimension. Gradually, they picked up the pace until they were all practically shouting.

“O-oh, I’m sooo close, Dimitri. I-I can’t hold myself any longer”

“Me too. I’m about to burst. Are you close as well, Dimitri?” 

Before he could answer, Dimitri instantly came with a roar and all he saw was white. The Byleths themselves screamed in delight, as they were reaching their peaks as well. He felt the most intense ecstasy he ever experienced. The weird dimension around him shifted again and he passed out. 

 

 

When Dimitri woke up, he saw the familiar blue sky of Fodlan. But most importantly, he saw the most beautiful sight of them all: the dazzling lavender eyes of Byleth looking full of love at him. 

His Byleth

His Beloved Byleth

Notes:

Let me give you a breakdown of my sandwich.

The top slice of bread is of course Byleth. The bottom slice can only be Byleth. What is the top? What is the bottom? It is all a matter of perspective. Both are valid and essential for a sandwich. A Byleth bun, as to say.
In between we have Dimitri. Now what is arguably the BEST and most universally loved sandwich filling? No need to think: the only right answer is CHEESE. Dimitri being the king so we can say he is The Big Cheese, as you would say.
In between the cheese and the buns, we find the mayonnaise. What is also white, has a really weird taste and texture? Cum. Therefore the cum symbolizes the mayonnaise
The plot point of interdimensional travel and the impact on it is scorching hot… like a grill. A GRILLED CHEESE SANDWICH

TL:DR: Dimileth is a grilled cheese sandwich with mayonnaise

Thank you for listening to my dissertation about Dimileth sandwiches
