Pet's Hero || BNHA Omegaverse (Sequel)

Chapter 8

Katsuki wasn't sure what to do next.

It's been about...well, seems like days to be honest, but it probably had been two hours or so since his rut started. In between the waves of pain, he'd managed to force himself up and check on Izuku in the bedroom, but he found that he wasn't there. Panicked, he'd started looking in his closet and all the places Izuku could have hidden in (considering he had hidden in his closet once already before, on their first week of meeting or so), but another rut-induced wave of pain hit him and he decided on laying down on the bed.

The rut was fucking with him, he could feel that much. If it were any other day, he'd be spam calling Izuku and everyone Izuku knew to understand where the hell his omega had run off to. As possessive and controlling as that was, he had more than enough reasons to do so, considering his sudden outbursts such as the one a few seconds earlier. Who knew what Izuku was thinking at the moment, especially with how much his mood swings were increasing?

Katsuki grunted as he turned around and was about to sit up to reach for the phone on the opposite side of the bed on his drawer, but right before he could do so, his hand pretty much buckled and went numb, his whole being shuddering as he sunk his face into the pillow in exhaustion and the shaky feeling. His body, as much as it craved his omega, seemed to be completely against putting any effort into finding him. How fucking ironic, Katsuki thought just as he felt another wave of pain overcome him.

Now, there was nothing embarrassing to him about what was happening. At least, that's what he wanted to think, every time his rut happened. And yet, he'd always avoided doing anything about it, even going as far as going out with Kirishima on movie nights or something of that sort during his small, not completely knee-buckling ruts.

Although, when big ones hit him like this time, he didn't do much. Had he never touched himself during a rut? Of course not, he'd definitely jerked off more than once for this. Did he enjoy it and totally not bang his head against the well the moment he reminded himself of those fog-minded times? Definitely.

Not.

Katsuki groaned again as his body stiffened, especially the space in between his groin. He hadn't realized until now that he'd make a horrible mistake, and that was the reason why his body was obeying him even less than it had before.

He was in the bedroom. Not a big deal, or at least, it wouldn't be to anyone else. Except, he was laying on Izuku's pillow, and they hadn't changed their bed sheets in four days by now. Which meant fucking god he could smell him like he was laying there under him.

Katsuki's phone rang, snapping him out of his thoughts, but Katsuki felt himself shiver again. He would definitely not be able to answer that, no matter who that was. Besides, they would have to apologize for making him feel so nervous about who was calling him, considering his current predicament.

"Fuck." Katsuki grumbled into the pillow, hips lifting up as he inhaled deeply. His hand was quickly and roughly making its way down and under Katsuki's hips, and he couldn't help the groan that escaped him as he took a solid grip around his girth.

It's all that goddamn asshole's fault. Kicking me in the balls and then leaving like that...could've at least said something. Katsuki thought to himself, that frustration turning into aggressive-lust as he inhaled sharply again, hand slowly moving up and down.

That wasn't enough though, and soon enough, Katsuki managed to climb under the blankets, and despite the heat of his own rut and the heat of the blanket, he stayed under it on Izuku's side, his pants half off and lingering on the top of his thighs as his boxers followed. Finally, he wrapped his fingers again around the throbbing heat in between his legs, and letting out a shaky breath, slowly stroked himself before tilting his head towards the pillow and inhaling once again.
