Chapter Text
It was the following Tuesday night when they both left to spend Sunghoon’s heat together, far away from the dorm where they wouldn’t disturb the rest and they wouldn’t be bothered. Sunghoon would be lying if he said he wasn’t a little nervous. Not only was this the first time he’d be spending his heat with an alpha, it was the first time he’d be spending it with Heeseung. While he trusted Heeseung with his life, he didn’t trust himself, especially not during his heat.
Just remembering how he had acted when he only had Heeseung’s hoodie made him cringe inside. He just knew he’d be annoying and clingy the whole time. Worse than that, he knew he’d become super demanding, more than just sexually. Their relationship had developed nicely and they were pretty mushy with each other, but neither was all that open in that regard. Sunghoon feared it would be too much for Heeseung, and he knew he wouldn’t be able to take it if Heeseung walked out on him during his heat.
He did his best to ignore the fear and worry, but decided that, before they got there, he had to talk with Heeseung about it. He was still working on remembering to communicate his feelings openly.
He breathed in deeply and loudly, catching Heeseung’s attention. “Will you be okay?”
“What do you mean?” Heeseung asked, confused and surprised.
“I mean, you’ve never been with an omega in heat before,” he started, rubbing his hands against his pants and not looking at Heeseung. “And I…” he paused to swallow, “I’m scared… that you’ll think it’s too much…” he admitted. “Because it’s- it’s more than just sex, I’ll need so much more and—”
Heeseung interrupted him, accidentally, by pulling him towards himself and into a hug. For a moment, Heeseung didn’t say anything and focused on calming down Sunghoon. The poor guy driving them could both hear them and smell them; the mix of Sunghoon’s scent reeking of anxiety and Heeseung's overpowering calming scent could not have been an easy scent to smell. Plus, their conversation had to make anyone uncomfortable.
“Listen, I really don’t know much of what I’m getting myself into,” Heeseung spoke with honesty. “But I want to do this with you, I want to be there for you, give you anything and everything you need,” he said. “And I may make mistakes, but I won’t leave you alone; I don’t want you to deal with this alone when I can help.”
“But what if you can’t handle me?” Sunghoon asked, uneasy.
“I’ll find a way,” Heeseung stated, full of conviction. “I’ll always find a way for you.”
Maybe, Sunghoon melted a little. He allowed himself to believe and relax. He allowed himself to trust Heeseung’s words in spite of his worries.
When they reached the place they’d be staying at, Sunghoon built a nest big enough for both of them. It consisted of their clothes combined, and this time, he did it without any guilt. Heeseung looked at him as he focused on building the nest, staring fondly at him. Sunghoon was slightly self-conscious about Heeseung watching him, he had the unbearable need to impress Heeseung with his nest. Deep down, he knew Heeseung would love whatever nest he built.
To be honest, they didn’t even wait for Sunghoon’s heat to start before they were already having sex. They were horny enough on the regular, with Sunghoon in pre-heat, they couldn’t resist. They also didn’t try too hard to hold back themselves.
Sunghoon was so consumed by his desire for Heeseung, he didn’t even realise his heat had started. Once it had started, though, Sunghoon got completely lost in it. Heeseung had him pressed against his nest and was already fucking him as deep as he could when his heat hit. He started whinnying more and his slick kept flowing out of him and Heeseung thrusted into him. It sounded filthy, but Sunghoon just didn’t care. He needed Heeseung to do more, so he pressed up with his ass to incite Heeseung to go faster and harder.
The message was understood by Heeseung in a second. He probably could tell Sunghoon had started his heat even before that simply by Sunghoon’s scent. Heeseung’s thrusts made Sunghoon lose his mind even more, after only a couple of seconds, he could no longer think at all.
Heeseung also took care of him in as well as Sunghoon had expected him to, at least in the sexual sense. He made him scream and moan until his voice wouldn’t come out anymore. Heeseung just couldn’t resist making Sunghoon’s skin all over. For the moment, he had access just to his shoulders and back, but that wouldn’t stop Heeseung.
“I’ve wanted to do this for so long…” Heeseung groaned as he bit down onto Sunghoon’s shoulder.
In his state, Sunghoon couldn’t tell him how much he had wanted it as well, but Heeseung probably understood by the volume of his moans. Sunghoon loved it. Now, once they were back, everyone would be able to tell who his alpha was. The people who would see already knew, but that wasn’t what was important. For every time Heeseung had wanted to mark Sunghoon’s skin and hadn’t been allowed, he left a hickey.
Later on, when they changed positions, Sunghoon would do the same. Soon, they were both covered in bite marks, hickeys and scratches.
“My beautiful omega,” Heeseung mumbled as he left a hickey particularly close to Sunghoon’s scent gland. They wouldn’t be mating anytime soon, but they would both be lying if they said they hadn’t thought about it. Sunghoon was a little too gone to think about the consequences; thankfully, Heeseung was still conscious enough.
That did not mean, though, that he wasn’t tempted. He caught himself more than once kissing over Sunghoon’s scent gland or dangerously nibbling over it. Fortunately, he could always stop himself before he did something stupid.
“Alpha,” Sunghoon moaned against the nest, drooling over their clothes. “Need you- your knot,” he pushed harder towards Heeseung.
“Just a little more,” he whispered, kissing behind Sunghoon’s ear. “Hold it a little longer,” he grunted.
“But I want it,” Sunghoon said with difficulty. “I want to come, want your cum…”
“You can come,” he said, his thrusts becoming erratic.
“Want to come on your knot,” Sunghoon could barely keep his eyes open and string words together, but he was determined. During his first time with Heeseung while in heat, he wanted to come only after he had been knotted. He was sure Heeseung would make him come multiple more times later on, he wanted to have this one.
“Okay, love,” Heeseung held Sunghoon by both his arms and started thrusting as fast and hard as he could. It didn’t take him long to start feeling his knot growing, movements becoming slower and more uneven. His knot made pulling out hard, and so he restrained himself to just pushing forward into Sunghoon.
“Please, please, please, ” Sunghoon was almost chanting. He couldn’t hold it for much longer, no matter how strong his will was. He was still in heat after all. He came as soon as he felt Heeseung’s knot reach its limit. He was familiar enough with it that he could tell once it was done growing. That plus Heeseung had buried himself as deep into him as he could while biting down on the back of his neck, barely avoiding his scent gland.
He felt how Heeseung cum filled his insides, it was warm and deep and it made him curl his toes and legs as much as he could. His own orgasm rippling through his body more intensely than ever before. He could feel pleasure coming from every nerve in his body, and it left him completely blind for a moment. He felt Heeseung all over him, around him and inside him. It was as if Heeseung was the only thing that existed, and Sunghoon was completely okay with it.
After such an intense orgasm, Sunghoon passed out for long enough that Heeseung’s knot had time to go down and Heeseung managed to clean him up a little. Sunghoon was in between glad that he didn’t feel as gross as he normally would, and disappointed that he didn’t wake up with Heeseung’s dick inside of him. At least he was in Heeseung’s arms, so he didn’t complain.
“Let’s do it again,” Sunghoon said as soon as he woke up, turning around in Heeseung’s arms. Heeseung had been drifting off to sleep as well, so it took Sunghoon kissing him to wake up and understand Sunghoon’s words.
“Drink some water first, baby,” Heeseung slurred, reaching over Sunghoon to where he had prepared a small bottle of water. Sunghoon pouted but complied, if drinking water would get him sex, he would drink the whole bottle.
Heeseung made sure to fulfil every wish Sunghoon had, while compensating for the time they hadn’t been able to do anything. He fucked him in every position he could manage to get Sunghoon in and knotted him just as many times.
It had been a little hard for Heeseung to keep up with Sunghoon’s intense demand for sex, but he had managed, somehow. It did drain him from most of his energy, but there was more he had to do than just fuck him.
As soon as they were done fucking, after his knot had gone down, he made sure to clean up Sunghoon and himself as best as he could. He fed Sunghoon throughout the day and gave him water after every round. At one point, he carried Sunghoon to the bathroom to give him a bath and make sure he remained relaxed and content. With how much Sunghoon had complained as he did that, Heeseung decided to continue with the wet cloth and towel after that.
Sunghoon’s favourite parts were the brief moments of clarity he got, when he could feel Heeseung’s arms around him as they cuddled to sleep. He loved how comfortable and safe he felt. He loved how loved he felt. Heeseung made him feel so much and he wasn’t scared of it anymore.
For the rest of his heat, Heeseung made sure Sunghoon ate as much as possible, and more than just energy bars. He made sure that Sunghoon drank enough and helped him get to the bathroom so he wouldn’t piss in his nest. It might have still happened once or twice while Heeseung fucked him senseless, though.
Once Sunghoon’s heat was over, he could confidently say that it had been the best heat he had ever experienced, even if he couldn’t walk back to the dorm on his own. Heeseung was more than happy to carry him back. Jay groaned at the state of their necks as soon as he saw them, while Jungwon shook his head knowing Sunghoon would be out from practice for at least a couple more days.
Sunoo looked like he was proud of them, which was a little weird, but it probably had to do with him being the first to confront Sunghoon about his feelings. He had been right and he had been the reason they got to where they were, at least partially. That had to bring him some satisfaction. Jake, on the other hand, looked like he knew too much. He looked like he had seen more than he had wanted to. Sunghoon was utterly confused, because none of them had seen anything. When he asked Jake about it, he wanted to be buried alive.
“We were talking about you two and Jay is sure you’ve done it in front of us at least once,” Jake confessed. “And it made me think to that time you were sitting on his lap while hyung was playing and how weird you were,” he continued, Sunghoon did not like where this was going. “And then I remembered how you had acted when you choked on absolutely nothing and I-” he stopped, sighing and rubbing his face. “I can’t stop thinking about it and whether Heeseung-hyung was in you or not.”
“Jakey…”
“No, do not tell me, I prefer not knowing than to get it confirmed, I’m not risking it.” Jake stopped him right away.
“Okay…” Sunghoon bit his lip and fidgeted, not knowing how to continue the conversation.
“God, I really didn’t want to know,” Jake almost teared up. Sunghoon didn’t know if he should feel mortified or relieved that Jake didn’t seem to care that much. In the end, he decided to be honest.
“I won’t lie, it’ll probably happen again,” he admitted. Jake groaned, but he obviously had been expecting that. “You’ll get used to it, probably.”
“I doubt you’ll give us another option,” he wailed, lowly. “Just don’t be too obvious, please.” Sunghoon shrugged, unable to give him the reassurance he sought.
Even if he should, Sunghoon didn’t care, he was pleased and happy. And later that night, while Heeseung hugged him tightly to sleep, he was still feeling the same. But more than that, he felt love and loved back.
