His Omega

For my 15th thread, I present an(other) ABO #kacchakothread set in my fantasy au omegaverse.

There's not much plot, really. I wanted more #kacchako dragon-hybrid smut and thus, this story was born.

Ochako was in trouble.

She and Katsuki were meticulous in tracking and planning around her heats; yet, of all the times for one to start suddenly, it just 𝘩𝘢𝘥 to happen while he was away.

The last time she experienced an unexpected heat was during his pursuit of her, when the hormonal response was unintentionally triggered.

Since then, the cycle happened at such a predictable pace that it was easy to ensure he was with her during every week-long period.

𝘌𝘹𝘤𝘦𝘱𝘵 𝘧𝘰𝘳 𝘯𝘰𝘸.

He had been gone for nearly two weeks on a diplomatic trip to a neighboring clan. Despite his hesitancy to leave her for so long, Ochako assured him that she and the children would be fine without him.

If she needed extra help, Mina was always available.

The importance of the trip was not lost on her; after months of attempting to reach the reclusive leader of the clan, Katsuki was finally able to arrange a meeting with him in an attempt to establish an alliance.

It was not an opportunity he could waste.

This also meant she couldn’t simply ask for him to return home. She knew it would be easy to reach out to him through their bond and tell him of her need, but she refused to do so.

Shortly after they mated, the two learned that an extensive psychic link existed between them, much like the telepathic connection he shared with the members of his clan.

As true mates, the connection they shared was even stronger, and allowed both to perceive what the other was thinking and feeling.

It had taken some time to become accustomed to, before she learned to appreciate the ability to communicate with him regardless of distance or who was around.

Still, there were times when it was cumbersome, however, such as the present moment.

He would feel her distress, unless she was able to maintain control of her emotions.

As she descended further into the heat, it would be difficult to do so but it was imperative she did.

If he felt her suffering, she had no doubt he would return immediately; so she must persevere, despite the fact the spark within her threatened to grow into a roaring flame that would consume her whole.

He was due to return the following day.

She could make it that long.

As soon she began to feel the telltale shifts in her body, she asked Mina to come take the children. Her friend tried to convince her to communicate her situation to Katsuki, but Ochako refused.

It was clear to her that a strong alliance would benefit their clan, and would further serve to establish Katsuki as king. While it was possible that negotiations were complete already, she could not risk it.

𝘚𝘩𝘦 𝘸𝘰𝘶𝘭𝘥 𝘣𝘦 𝘧𝘪𝘯𝘦.

At least, that was what she repeated to herself, a whispered mantra to carry her through the pain of starting a heat alone.

The first signs of her heat had started the day before.

She did her best to temper the sweltering flames that lit her veins, putting forth maximum effort in maintaining a state of homeostasis. Her omega had grown quite spoiled in the two years since she and Katsuki found one another, and was now throwing a fit at being without him.

Nevertheless, Ochako had already survived one day. She just needed to get through to the next and then her Alpha would be there to take care of her.

A small, rational voice in the back of her mind insisted that she would face his displeasure for not alerting him.

She quickly pushed it to the side.

In the first months of their bond and marriage, it became clear that it was difficult for her to ask him for help.

Even when she 𝘬𝘯𝘦𝘸 she needed him, she tried to maintain her independence.

It was still a point of contention between them, but no matter how many times he repeated that he 𝘸𝘢𝘯𝘵𝘦𝘥 to ensure her pleasure and safety alike, she remained stubborn.

She could only hope that her willfulness was enough to carry her through until his return.

It was imperative that she focused all her energy on remaining calm and keeping the fire within her at bay. When she first realized what was occurring, she told herself he would be there soon enough.

There was no need to interrupt his stately duties for something that she should be able to handle.

Except, she seemed to have conveniently forgotten that she hadn’t spent a heat alone since her very first heat, the only one she experienced before meeting Katsuki.

In the time that passed since then, she forgot just how miserable the omega within her became when not placated by her Alpha.

Ochako groaned as the fever that consumed her climbed to a painful, blinding level.

She had already tried relieving some of the tension herself, but to no avail.

Although she rubbed herself in the same way he did, it didn’t bring the same sense of relief. The fingers she inserted into her dripping cunt could hardly compare to the way he stretched her out.

It almost felt insulting to even attempt to fulfill herself in the same way he did.

Her body was in a constant state of wetness.

Slick leaked from her folds steadily, preparing her body for an Alpha that was absent. It coated her inner thighs and mixed with the sweat that covered every inch of her skin as a result of her prolonged torture.
