Diluc was on his way home from the tavern, hand rubbing over his stomach absentmindedly. It was late, but still he wondered whether Kaeya would be there or not.

Despite his mantra of how lazy the knights were, he knew that his mate at least took his job seriously.

His thoughts drifted from his alpha to their relationship. They’d been mates now for 4 months, together for much longer, and his omega was getting restless.

He wanted a pup, but he wasn’t sure how Kaeya felt about it. Was it too soon? Did Kaeya even want a family?

Diluc knew they should have talked about it sooner, but really it wouldn’t have made a difference. He would never love anyone the way he loved Kaeya, and if his knight didn’t want a family he would have to make do.

Still, he yearned for it. His hands brushed his flat stomach again, imagining himself round with pups. He decided then and there that if Kaeya was home he would ask him about it tonight.

Upon opening the door he smelled the familiar scent of snow and calla lilies.

“Kae?”

He hung his coat up and removed his shoes, spotting his mate curled up by the fire, waiting on him.

“Welcome home sunshine.” Kaeya set down his glass of wine and opened his arms. The red head smiled softly and sat down next to the alpha, quickly cuddling up to him. They sat in silence for a few minutes, enjoying the others' presence before Diluc decided to broach the topic.

“Kaeya, I was wondering. Would you…” he hesitated but Kaeya only hummed in question.

He took a deep breath before continuing, “Would you want to start a family?”

Kaeya’s eyes widened and he froze for a second. Diluc started to fear the worst, pheromones spiking and souring with anxiety. Kaeya’s alpha responded immediately, releasing a soothing scent into the air and hugging Diluc closely.

“That’s something you would actually want with me?”

Diluc sat back so he could look Kaeya in the eyes. “I want that more than anything. I want a family with you Kae.”

Kaeya smiled, “I want that too Luc”

Diluc leaned in, lips going to Kaeya’s ear, “Then what are you waiting for? Breed me.”

They barely made it through the door to the bedroom before clothes were coming off, hands exploring each others bodies. Kaeya dropped Diluc onto the bed and pulled off the omega’s pants and underwear slowly. His hand dropped down, sliding through soft folds.

“So wet for me already sweetheart.”

Diluc moaned and widened his legs to give Kaeya access. The knight lowered his head and started sucking bruises onto plush thighs. Diluc wound his fingers into blue hair as his alpha got closer and closer to the spot he needed him in the most.

“My sweet omega,” Kaeya murmured between kisses, “you smell so good.”

“Kae, please- ah!” he cried out as lips wrapped around his clit, sucking lightly.

Kaeya alternated between licking and sucking, moaning at the taste. He added a finger, then two. The omega was dripping slick faster than Kaeya could drink it up. It wasn’t long before Diluc could feel that familiar pressure building inside him and he tried to warn the other.

“‘m gonna- mmm, gonna come.” he pulled on blue hair and rutted up into his alpha’s mouth, even more slick gushing out as he came. The alpha licked up the excess slick and Diluc whined from the overstimulation.

He pulled Kaeya up insistently. Tongues met in a messy but deep kiss and he could taste himself on the other man’s lips. A hand cupped Diluc’s cheek and he could feel the alpha’s cock brushing heavy between them and he whined again.

“Alpha, I need you. Please!”

“Shhh, I’ve got you Luc,” he sat back and gripped the omega’s legs, pushing them up and nearly folding the other man in half, “You’re so beautiful, so good for me.”

He lined himself up and started pushing in slowly, watching for any signs of discomfort. Moans filled the air when he bottomed out and he pressed kisses to the omega’s neck.

He stayed still for only a moment before pulling out and thrusting back in. Gasps and moans drowned out the wet sound of their bodies meeting. Diluc gripped Kaeya tightly, nails scraping down his broad back.

He could feel the alpha’s knot beginning to swell and heat pooled in his belly. A few sharp thrusts later and there was an audible pop as the knot pushed inside the omega’s pussy, locking them together and pushing Diluc over the edge.

He shouted as he came for the second time that night, muscles gripping the cock inside of him.

Kaeya ground his hips inside a few more times before groaning as he came, hot cum filling up his omega.

Panting he pressed a few more kisses to Diluc’s neck before maneuvering them onto their sides, holding the smaller man close.

“I love you Luc.”

Red eyes met blue, tired but satisfied.

“I love you too Kae.”

Months later Diluc was headed home, hands brushing over a swollen belly. This time he knew Kaeya would be waiting for him, the knight refused to work late ever since finding out he was pregnant, despite Diluc’s insistence that it was too early to be so concerned.

Still he thought it was sweet, and he was so excited to grow their family. He smiled to himself softly as he opened the door.

“Welcome home Luc.”

“I’m home Kae.”

Fin.
