*this story's depiction of sex might not be accurate. it's hard writing a subject i know nothing about. but, hopefully it's not too bad.*

Ch, 3. What next?

The sun was high when Katsuki finally opened his eyes. He groaned and went to pull the sleeping bag over his head to protest getting up, but noticed there was an arm around his chest. His eyes fallowed the arm to the body he knew it belonged to.

Izuku was still passed out and drooling on Katsuki's lower shoulder; nuzzling the sleeping bag.

He blushed at the adorableness and quickly looked away.

He couldn't help but wonder just… how? How can someone so cute be SO GOD DAMN HOT at the same time?

They really did do it all night long.

The last thing he remembered before waking up was the sun rising.

The escapades of the night before replayed in his mind as a light blush dusted his face and he buried his head in his hands.

His heart began to beat faster, but Izuku's steady breathing and almost inaudible snore seemed to calm him down.

His body was suddenly just as sensitive as it was the day before. Izuku's breathe sent a chill down his spine. The nerd had no idea how he affected him even while sleeping.

It really didn't help that Izuku was still hard and his dick rested on, but not inside, Katsuki's… Katsuki's… omega hole? He didn't know what else to call it. All he knew was that dick goes in and nine months later baby comes out... and that all omegas had them from birth, but mostly go undetected until their first heat. Was it a vagina? Oh! He didn't care. The only thing on his mind at the moment was that he wanted the, not so little, nerd awake and rearranging his insides.

But, at the same time… he didn't want to wake him because he was so peaceful and adorable.

He figured it would be better if he'd let him sleep.

Funny, the campsite was quiet, too quiet. Where were the adults?

A sudden realization struck him. He was naked… he was naked and being spooned by Izuku who was also naked. Did any of the adults check on them while they were sleeping? His blood ran cold and he broke into a nervous sweat.

No, his mom would have yelled if they did. Although, that fact didn't ease his worries.

"Kacchan?"

VVVVVV

Izuku's eyes didn't want to open, but he was conscious so he probably should open them. He wanted to roll over and go back to sleep, but he was kinda comfy the way he was.

But, Kacchan's sweat was starting to make things a bit sticky and uncomfortable. It also didn't help that the sun seemed to turn their tent into an oven.

And it really didn't help that he could smell his pheromones. They seemed stronger than the night before; if that was possible. That, and he was resting on his shoulder. Also, he was fully aware of what the two spent the whole night doing. It almost felt like a dream, but his sore, bruised, and naked body, and Kacchan's naked body in his arms, proved otherwise.

He honestly didn't know if he should scoot over and get some relief or embrace the heat and go back to sleep. He really didn't want to move. He wanted to stay there and breathe in Kacchan's sent, commit it to memory just in case things were going to stay in the woods when they got back home. He hoped that wouldn't be the case, but it was a possibility.

But, Kacchan seemed tense. His whole body went stiff.

Izuku opened his eyes, squeezed him a bit and spoke in a groggy whisper. "Kacchan?" He yawned. "Something wrong?"

VVVVVV

Katsuki's eyes widened as he heard Izuku's low morning voice in his ear. It sent another shiver down his spine.

It didn't help that Izuku groaned and buried his face into his back as he hugged him a bit tighter, leaving absolutely no gap between them.

Katsuki bit his bottom lip and tried not to moan.

Between his sent, his erection, his voice and how close he was, Katsuki knew he had to have more; that the night before wasn't enough. He was already turned on, but now he was just complete putty in his hands.

He didn't want to be just any alpha's bitch, but he'd gladly be Izuku's.

Izuku's bitch?

Yeah, Izuku's bitch.

He had to be Izuku's bitch. No way he'd let the nerd go and be with someone else. No, he had to have him all to himself. Fated mate or not. He didn't care. He had to have him for the rest of their lives. Hell, he'd even bare his kids if it meant he'd be his… although, he still didn't want kids, he'd do it for Izuku… he'd do it for Izuku's dick.

He now understood all the articles he found saying omegas can form sex addictions, because he couldn't get enough. He was satisfied from the night before, but also craving more.

"Have you… have you marked me?" He tried not to sound as thirsty as he was, but his voice still cracked.

"Hm?" Izuku nuzzled his back. "What do you mean?" It was muffled, but audible.

"Have you marked me? Made me your mate… your bitch." He reiterated.

Izuku groaned, which only made Katsuki even more desperate. "I can mark you, make you my mate if you want. But, Kacchan I respect you too much to make you my bitch." He rested his chin on Katsuki's shoulder.

"Then disrespect me and make me your bitch." He wasn't going to hold back anymore. "And when you're done making me your bitch, fuck me. Fuck me for the rest of our lives."

"Kacchan…" Izuku began. "You're so wet." He moved his hand from his chest and moved it up to cover his eyes. He tilted his head a bit so he could easily get to his scent gland that had a tiny birth mark on it. He then began to pepper kisses on his neck and lick his skin. "I'll make you my mate and make love to you for the rest of our lives."

"Just do it and me nerd." Katsuki couldn't bare it any longer.

"Hm." Izuku licked his scent gland sending a chill down his spine. He then bit down, but only enough to just break the skin. He then began to suck a bit, mixing his saliva with his blood. He licked the spot when he was done to help the wound close.

Something new washed over Katsuki, it wasn't pleasure nor was it pain. It also didn't effect his lust. It just… was.

Odd, he thought he'd feel completely different after being marked. Perhaps closer to Izuku. But, he felt the same. Did he not mark him? No, he did… every account he read said it felt like being bitten by a vampire and Izuku accomplished that feat. Oh yes, did he accomplish that.

Izuku's hand uncovered his eyes and traveled gently down his torso to a little patch of hair above his dick. He traced the line even further down with his fingers and lightly grabbed the tip of Katsuki's very erect penis, lightly rubbing it with his thumb as he peppered kisses on his back.

Katsuki gasped for air, not being able to breathe as drool dripped out of his mouth. He didn't even realize he was hard himself.

"Kacchan." Izuku's voice was low and breathy. The smooth motion of his thumb made him squirt a little bit. He then slid right inside of him and began thrusting. "Can you cum in two places at once?"

Fuck! The nerd was sexy as hell.

He tried to, he really did, but he was overstimulated and blew his load before he came in the other spot. But, it was a very short gap between the two.

The sensation he had come to understand as an orgasm washed over his body from the two points simultaneously.

He felt Izuku pull out and pull away.

He looked over and found him in a half lean, half sitting up position on his sleeping bag and smiling at him.

Katsuki rolled over to lay on his back as he tried to catch his breath.

Why the distance all of a sudden? Did he do something wrong? Was he mad?

Izuku slid further into his sleeping bag and laid down, grabbing Katsuki's hand to hold it.

Before he could say anything, a sound made them both jump a little and scramble to look like they had been sleeping the whole time.

VVVVVV

"Are the boys still sleeping?" Masaru raised an eyebrow as the adults came back to campsite after going for a morning hike.

Inko gazed at the boys tent. "Nothing looks out of place."

Mitsuki pointed walk over to the tent. "Inko can you see if they're ok?"

Inko shrugged. "Sure."

She unzipped the door flap, poked her head in and gazed down at the two supposedly sleeping boys. She counted the marks she could see and noticed they were clearly not wearing shirts. She could tell neither of them were wearing anything at all. She watched as their chests raised and lowered in quick motions. So they weren't asleep. She smiled knowing exactly what the boys had been up to and closed the door flap.

She hadn't told anybody, but she had known for years that something like this would happen.

She turned to the other two with a warm calming smile. "They're fine, just tuckered out."

Mitsuki and Masaru sighed in relief.

She walked closer to them and cupped her hands together. "It's happened." She whispered.

Mitsuki and Masaru nodded knowing full well what she was talking about.

After all, they all knew, the tiny mark on Katsuki's neck wasn't a birthmark.
