Crown Prince Izuku had an assassination attempt on his life, so his parents hire knight Katsuki. The handsome guard turns heads everywhere they go. He never pays them any attention. Izuku is infatuated with the knight. He tries to seduce Katsuki, but he seems immune to his charm.
Izuku still remembers their first meeting. He challenged the knight to a duel. Katsuki had him on his back within seconds, a sharp blade pressed against his neck.

When Izuku yielded, he smirked, then murmured lowly in his ear, “Next time, I won’t go so easy on you, /my prince/.”
He helped Izuku up, then brushed the dirt off his cheek with his thumb. The knight left him speechless and aroused.

Katsuki takes his job a little too seriously. He follows Izuku everywhere. Once, he went to get a glass of water at night and the knight insisted on escorting him.
Rumours about them quickly spread through the palace.

“I bet the knight takes really /good/ care of the prince.”

Izuku isn’t naive. He knew what the implications were. Katsuki told him to ignore them. The two were never seen without the other, so the gossip grew more rampant.
His cheeks tint whenever he thinks about them.

“I heard they have private ‘sword fights’ at night.”

“I don’t blame the prince. If I had Bakugou as my personal knight, I’d never leave my chambers too.”

Izuku wishes they were true. It’s hard having Katsuki near him all the time.
The prince starts touching himself to relieve tension. On the rare nights where he’s able to steal a moment in his bed, he ruts his hips against the sheets.

He thinks about the way Katsuki growls in his throat and wonders what it would sound like from behind, right in his ear.
Sometimes, he uses his private bathing time to stroke over his cock and explore his hole. He knows he has to be quiet since Katsuki’s right outside the door.

The chance of getting caught turns Izuku on even more. He holds back his shaky moans and imagines the knight hearing him.
He’d come in to check if he’s hurt, just to see him in the act of bringing himself to completion, his name on his lips.

One day, Izuku sneaks to the library and steal a book on seduction. Katsuki gives him an earful and threatens to spank him, not knowing that’s what he wants.
Izuku takes some tips from the book and purposely puts on a pair of too tight trousers. He then asks his knight for assistance.

His plan backfires.

Katsuki scoffs and calls him a “Deku”. After he pulls the pants over Izuku’s plump ass, he warns him to throw them out or he will.
The more time they spend together, the harder Izuku falls. He wants to know what kind of lover Katsuki is.

His knight won’t give him the time of day. He starts to wonder if he’s unattractive. Katsuki has seen him naked multiple times, but he never bats an eye. Izuku backs off.
The knight continues to stay professional until the grand royal ball.

Izuku despises dressing up in fancy jewels and robes. The crown on his head feels heavy and he feels uncomfortable with everyone’s eyes on him.

When his knight spots him across the ballroom, he strides over.
Before Katsuki can reach him, another royal asks him for a dance. The prince looks at his knight, but his expression is unreadable.

Without thinking, Izuku accepts the stranger’s hand. He lets the man pull him close. The stranger leads them as he compliments him on his beauty.
Closing his eyes, the prince imagines he’s with Katsuki. The illusion is ruined when the hand on his waist slides dangerously low.

Izuku stiffens. He’s ready to crush the pervert’s hand, but he’s ripped out of his arms. He blinks and Katsuki is in between them.

He’s furious.
Katsuki tightens his crushing grip.

“Give me one good reason why I shouldn’t break off your hand.”

The man profusely apologizes. His knight sighs.

“Not to me, you fucking idiot. Apologize to the prince.”

Izuku accepts the apology and watches the palace guards escort him out.
After the prince assures his guests that he’s fine, his knight asks for a dance. He agrees.

“Thank you-“

“I know you were trying to do.”

Izuku freezes. “W-What do you mean?”

“Don’t play dumb, your highness,” he hisses in his ear. “I know you were trying to make me jealous.”
TBC. Not me starting another wip. Royal aus are my weakness so I had to. Thanks for reading! I love your QRTs, so feel free.
