Akira/Past!Flynn, sleeping in the same bed together for the first time?
(Im using @yarrayora's name for past!Flynn, which is Mamoru. This is obviously by its nature FILLED TO THE BRIM with headcanons. Also as usual im sending 3 sentences prompts to die and im just doing a whole drabble.)
Akira knew that Mamoru lived in an empty apartment, but actually seeing it was something else. This was the reason, he realized, that whenever they were together off-duty, they always went to Akira's place. Featureless walls with only a few scant pieces of small artwork up, no pictures or anything, very few personal effects. It was the home of someone who rarely got to keep a home, someone who didn't know how to settle down and truly live in a place.
Even though he was an adult now, his past as an orphan was very clear.
There were some simple furnishings, what was necessary for a kitchenette, a small desk with a straightbacked chair, a bookshelf with mostly either old schoolbooks or nonfiction content books, a wooden wardrobe with a small mirror and hairbrush resting on top, a simple, but decently sized, bed. This could be anyone's room, and it made him saddened that this was how Mamoru lived, even now.
Akira's place was different, more lively. He lived close to his family so there were often visitors, and he at least owned a television and a couch, had boardgames in the closet, and so on. His decorations weren't too elaborate, he did live mostly for his work, but there were some movie posters and photos of family and friends. But nothing of the sort was in this barren space. It was clean though, immaculately so, everything prim and proper, and it was clear that Mamoru settled so easily into military life. Even the sheets were tucked into hospital corners.
Akira was fairly certain that he was the first person other than Mamoru or his landlord to ever be welcomed inside.
Mamoru was a few steps ahead of him, smiling but tired, they had just finished a long mission, been away for a few days. They had showered and changed on-base, but Mamoru lived a little closer to it, so he had offered to invite Akira to his for once. It was late now, the starry night sky visible through the blinds of the small window across the room. They both were ready to just collapse.
"You can take the bed," Mamoru was saying softly, "I have a futon in the closet that I'll get out."
When they were at Akira's, one of them usually took the couch. They were dating, but it felt like a barrier they shouldn't cross, not yet, but maybe it was time for that to change. "I'm not making you sleep on your own floor," Akira said as he shook his head.
"Well, I'm not letting you sleep on my floor," Mamoru replied, and he looked confused. Akira didn't usually make a fuss about that--and with how careful they had been in developing their relationship, Akira wagered that Mamoru hadn't even considered what he was about to suggest.
"Your bed is big enough," he said simply, a small smile starting to tug at the edges of his lips.
Mamoru's eyes went wide, but Akira could see nervous excitement glittering in them, "Oh. Are you--are you sure?"
"I wouldn't suggest it if I wasn't. Is that alright with you?"
"Yes!" Mamoru was practically bouncing on his toes, all evidence of his exhaustion suddenly vanishing as if they weren't both bone-tired.
They chatted a little as they got ready to sleep, Akira throwing his backpack in the corner. Mamoru seemed a bit nervous though, and Akira understood--he knew he had in general more relationship experience than him, and even though all he intended was sleep, he knew that Mamoru sometimes got a little nervous, especially when he was doing something new. New like sharing a bed with the person you loved.
Akira layed down first, settling himself in on the side closer to the wall, and he pulled the sheets back, "You coming?"
Mamoru nodded, approaching and joining him, a little tense, his face reddening as he shifted uncomfortably. He was on his back, and Akira had moved to lay on his side, looking at Mamoru. He always liked seeing him with his hair down, and even with sleepiness tugging at his brain, he kept himself awake just so he could look at him. "It's alright for you to look at me," Akira said softly.
Mamoru still hestiated a moment before turning his head and meeting his gaze. He looked shy, "I...don't want to be too...clingy."
"You can be," Akira smiled, "I don't mind. I'm the one in your bed, Mamoru."
Mamoru turned to lay on his side as well, facing him, "I'm...going to hold you, then."
He was emboldened now though, his usual confidence returning as he embraced Akira, pushing himself closer, and Akira quickly returned the favor, although it was a little awkward to figure out where to put his limbs when Mamoru dragged him to his chest. It was nice though, warm, and Akira's breathing started to deepen.
"Can I hold you while you sleep?" Mamoru whispered into his hair.
"Sure, just make sure you sleep too."
"Mmn," Mamoru hummed, his hands moving to soothingly stroke Akira's back, lulling him to sleep.
