Izuku whimpered, biting his lip hard to prevent himself from crying out.

Katsuki's teeth sunk into Izuku's neck, knot pressing deeply into the Omega.

The greenette was held close, body flush against his Alpha's as he was finally marked. Izuku closed his eyes, panting as Katsuki released his neck.

"Sorry..." Katsuki muttered and gently cleaned up the tender mark. "Might've bit a little too hard..."

"It's okay..." Izuku looked up at the King and smiled. "I'm finally yours..."

Katsuki chuckled, brushing his nose against Izuku's before kissing him softly. Izuku cupped his Alpha's face in his hand, relaxing beneath him.

The King sighed happily as their kiss broke. "I am never... Never letting you go again."

Izuku giggled, twirling a lock of blond hair around his finger. "Is that so?"

"That's so. And anyone that tries to take you will die."

The Omega laughed, squeaking as they rolled and he was now on top of the Alpha. He propped himself up on Katsuki's chest, looking down at him. "I've been thinking."

"Oh, boy."

"Hey!" He smacked Katsuki's chest as the Alpha laughed. Izuku huffed. "Anyways... I've been thinking about names for the baby."

Katsuki hummed, running his fingers up and down Izuku's back. "Yeah? Got a list?" He asked, admiring his Omega.

Izuku smiled down at him. "A small list... I'll show you what I've got, later."

"Alright..." Katsuki looked up into Izuku's eyes and brushed a stray strand of hair out of his face.

The Omega closed his eyes, content. "I think... This is the first time without you being angry or stressed out..."

Katsuki scrunched his nose and paused. "What are you talking about?"

Izuku tilted his head. "Everytime we've had sex is because you were angry about something or really stressed because of your duties. This is the first time we've-"

"No it's not." Katsuki flicked the Omega's head.

"Hey!" Izuku pouted and rubbed the now aching spot on his head.

"We've had sex plenty without me being angry or stressed."

"What are you talking about?"

The King huffed and rolled his eyes. "You remember the first time I stayed with you overnight?" Izuku hummed and placed his chin in his hand. After a moment, he nodded. "Well... That day, I had been watching you with the horses... There were some children and you tought the ones that were brave enough how to ride. That was when I first realized I had feelings for you..."

Izuku smiled softly, tracing circles into Katsuki's chest. "That's actually really romantic... I had always wondered why you stayed with me that night... Tell me another time?" He probed, earning an eye roll.

"Let's see..." Katsuki sighed, shifting to get more comfortable. "Oh, the hunting party."

"When we ended up separated from everyone?"

"Yup. I was angry, but mostly at myself for not telling you what I was feeling." He adjusted the pillow under his head. "So, I was trying to show you."

Izuku laughed. "You have a funny way of showing it. We didn't have proper bedding so I had bruises and cuts all over my back. I couldn't lay properly for a week."

Katsuki grumbled, "hey, I never said it was a good idea or good timing."

The Omega grinned and nuzzled back into his Alpha.

The blond smiled down at his mate.

"I'm glad it wasn't always one-sided," Izuku murmured, closing his eyes.

"Yeah..." Katsuki closed his eyes.

They both lay quietly, basking in each others embrace.

Once Katsuki's knot deflated, he squeezed Izuku and scented his heavily.

The Omega squeaked and laughed, holding onto Katsuki as they were rolled back over. "Kacchan!"
