Tails and Tired Engines

Iida 

Y/N sat at his desk, the faint glow of his computer screen illuminating his dorm room in UA's student housing. His dragon tail swayed lazily behind him as he focused on his homework, occasionally brushing against the chair leg. It was late, but Y/N didn't feel tired.

A sudden knock on his door made him glance up. It wasn't unusual for someone to stop by, but he could already guess who it was.

"Come in," Y/N called, not taking his eyes off his screen.

The door creaked open to reveal Tenya Iida, his uniform slightly disheveled and his signature glasses resting a bit askew on his nose. He looked exhausted, his usual energetic aura dulled as he stepped inside.

"Y/N," Iida greeted, his voice soft and tired, a stark contrast to his usual booming tones. He didn't wait for an invitation before crossing the room and collapsing onto Y/N's bed with a heavy sigh.

"Long day?" Y/N asked, turning in his chair to look at his boyfriend.

"Grueling," Iida muttered. "My engines overworked during training, and then I had student council responsibilities on top of it. I feel like I've run a marathon... twice."

Y/N smiled softly. "Well, you could've gone to your dorm to rest. Why come here?"

Without responding, Iida reached out and gently grabbed Y/N's tail, the familiar gesture drawing a chuckle from the dragon boy.

"You always do this," Y/N teased, letting Iida pull his tail closer.

"Your tail is comforting," Iida admitted, his voice muffled as he nuzzled into the soft scales. He wrapped his arms around it like a makeshift pillow, his expression softening almost instantly. "It's warm and calming, and it smells like you."

Y/N couldn't help but laugh at the sight of his usually composed boyfriend clinging to his tail like a lifeline. "You're hopeless."

"I'm tired," Iida corrected, his eyes already fluttering shut. "And I'd like it if you joined me in bed. You've been at that desk for hours."

"I have homework, Tenya," Y/N pointed out, though his resolve was already wavering.

"Homework will still be there tomorrow. I might not be," Iida countered, tugging the tail gently as if to emphasize his point.

Y/N sighed, feigning annoyance as he saved his progress on the computer. "You're lucky I love you, you know that?"

"I am well aware," Iida replied with a small smile, not letting go of the tail even as Y/N climbed into bed beside him.

As soon as Y/N settled down, Iida shifted closer, resting his head against Y/N's chest while still holding onto the tail. His breathing slowed, and within moments, he was fast asleep.

Y/N smiled, wrapping an arm around his boyfriend. "Goodnight, you big engine nerd."

And as the steady hum of Iida's breathing filled the room, Y/N decided that finishing his homework could wait.
