Chapter Text
Coming home to a welcoming smooch on the lips was one of the many things Sips loved about Sjin. There was something in the lingering taste of his boyfriend that calmed him down after a stressful day at the dirt factory.
Today was different, as he quickly found out once he entered their home and Sjin had taken a firm hold on him and stuck his tongue down his throat, his scent and taste slightly unusual.
After the initial shock had waned, he managed to pull himself free from the other man. ”Woah, honey,” he said, smirking smugly. ”What’s—”
"I’m in heat," Sjin whispered, his voice barely audible over his insistant purring. His eyes were unfocused and flickering.
"What?" Surely he had heard wrong.
Sjin leaned down to pepper Sips’ neck with wet kisses. ”I-I’m in heat, Sipsy,” he repeated, a faint whine in his throat. ”Please, I need you, right now.”
Sure enough, Sips could feel Sjin’s throbbing erection through the fabric of their clothes. To say he was hard would be an understatement; Sjin’s member seemed to be on the verge of bursting. It couldn’t possibly be comfortable.
Deciding not to ask why he hadn’t known about Sjin’s mating instincts before now, he brought his hand to Sjin’s face and pulled him down for a sloppy kiss. Sjin whined, longingly.
"Well, I guess we’re gonna have to do something about that," Sips said, smirking, feeling Sjin’s unusually sweet breath near his face. "Aren’t we?"
Sjin half giggled, half moaned with happiness, pulling Sips with him to their bedroom, almost making Sips topple over. He watched as Sjin wrung his clothes off himself in record time before beginning to help Sips with his own clothes. Sips gently slapped his shaking hands away to unbutton his shirt, all the while receiving excited, wet kisses on the lips.
Once the shirt was off, he wrapped his beefy arms around the other, the kiss deepening. He could feel Sjin’s purring in his throat, could taste the sweet scent Sips could only guess was his outer-worldly pheromones.
Gently, Sips pushed Sjin down to sit on the edge of the bed. He flashed him a quick, mischievous grin before he got down on his knees, pushing Sjin’s legs apart.
Sips could actually see the pulse in the cock before him, and he could only imagine how long Sjin had waited for him to come home to take care of it. His poor babby.
With one hand on the shaft, he slowly took the head of the cock to his lips, kissing it teasingly before taking it in, gently rubbing the sensitive spot with the flat of his tongue. He winced when Sjin’s hand suddenly grabbed a handful of hair, but kept going regardless. Tentatively he massaged the shaft with his tongue, his head bobbing softly.
It didn’t take more than a few seconds before Sjin came with a soft moan, his come practically coating the inside of Sips’ mouth. Sips swallowed, and continued massaging Sjin’s cock until his climax had ended.
After a few seconds he was surprised to find that Sjin hadn’t become softer in any way or form; his excited cock was still throbbing as hard as it had at the start.
"Sjin?" Sips asked curiously.
Sjin cupped Sips’ face with his hands, his grasp gentle but firm. ”Take me, Sips,” he whimpered, his eyes still flickering as if he were confused. ”Please, I’m so horny. I need you.”
Well, how could he say no to that?
Standing up, he left a come-stained kiss on Sjin’s lips before pushing him down onto the bed. Reaching for the night stand, he took out the water based lubrication and smeared some of it onto his own cock before reaching for Sjin’s entrance with his hand.
Surprised to find that not only was Sjin already wide enough to accomodate him but also coated with what he could only guess was natural lubrication, he decided in stead to grab his legs and lift them up, letting them rest on his arms, to gain easier access.
The look on Sjin’s face, that longing look of desperation, was almost mesmerising. He took a few moments to admire the expression, before Sjin’s whine snapped him out of it, coaxing him to enter his needy boyfriend.
He soon found that Sjin wanted it as hard and fast as possible, what with Sjin reaching to grab onto Sips’ hips to pull him closer. Sjin’s eyes were half closed, dull with ecstacy, and his mouth open, as if prepared to let out any sound he should make during their session. And make sounds he did.
Gasps and moans and whimpers, accompanied by almost violent twitches which Sips eventually realised were orgasms; Sjin’s stomach had been coated at least twice by his own come by the time Sips felt the warm feeling build in the pit of his own stomach. Just as he came inside the other, he saw yet another burst of come splutter onto Sjin’s stomach.
He groaned, cheerful and exhausted, as he pulled out. He felt Sjin’s hand grab his wrist.
"Please, Sipsy." There was no disguising the desperation in his voice. "I need more."
Sips spluttered, at a loss for what to say or do next. ”But— but my dick is all worn out!” he explained. ”It needs a break, Sjin. I’m only human.”
Sjin’s grip tightened. ”Use your fingers!” he insisted, breathing heavily, as he let go of Sips’ wrist and turned himself around and lay on his stomach. ”Please, Sipsy…”
An amused smirk spread on Sips’ face at the sight of this. He’d never seen anything like it. Placing a soft kiss on the small of Sjin’s back, he pushed his two middle fingers inside of him and was rewarded with a content sigh from Sjin.
"More," Sjin whispered lazily.
Three fingers now. Sips couldn’t help grinning.
"More, please, Sipsy."
"Jesus, Sjin…" But Sips complied, shoving four fingers inside him, searching for the spot that would make Sjin go wild, if not wilder than he already was. Prodding at what he imagined was the spot in question, Sjin swiftly came a fifth time, with a high-pitched groan.
Their bed was a sticky mess. Surely Sjin would be exhausted—
Apparently not; Sjin turned to his boyfriend, grabbed him by the hips and pulled him close for a deep, wet kiss. Sips could still smell the sweet pheromones, or whatever they were. There was something familiar about the smell. Chocolate, perhaps?
"Just one more," Sjin wheezed against Sips’ lips. "I’m… just… ohh…"
Leaving a soft, lingering kiss on Sjin’s lips, Sips complied once again, this time by going back down onto his knees. The familiar cock before him wasn’t as insanely hard as it had been to begin with, but it was clear that Sjin needed just a little more.
He went deep; the head of Sjin’s cock nudging the back of Sips’ throat. He tried not to gag too much, and kept going deep until Sjin’s whimpering told him he was getting close. He pulled back until just the tip remained in his mouth, gently massaging the sensitive area.
There wasn’t much left of Sjin’s nervous substance, but Sips kept going until the twitching and moaning ended, and — finally — the cock seemed satiated, beginning to become flaccid. He pulled back to look up at Sjin, who was panting, his legs shaking.
The smell of chocolate was still strong, but Sips noticed it was dwindling. He gently coaxed Sjin into giving him some room on the bed, and lay down next to him, grinning at him.
"In heat, huh?"
Sjin laughed, his eyes closed, looking blissful. ”Yeah.” He heaved a sigh of exhaustion. ”Wow. That was hot.”
"Is that why they call it ‘heat’?"
Sjin turned to look at him with a playfully disapproving look, before rolling over to huddle up next to him. He wrapped his sinewy arms around him, caressing him with his thumb, and snuggled up against the nape of his neck.
"Thank you, Sipsy," he murmured softly, his mustache tickling Sips’ skin. "That was great."
"Yeah," Sips agreed, smiling. "Does… does this happen often?"
"Once a year or so."
"That’s good," Sips muttered. "It was fantastic and all, but I don’t think I’d be able to keep up with you if this happened more often."
Laughing quietly, Sjin placed a soft kiss on his lover’s throat.
They lay in silence, simply enjoying each other’s presence, gently stroking the other’s skin, breathing, heavily at first, then more softly. Time stood still.
"Somebody should probably clean up this mess," Sjin murmured tiredly.
Sips laughed. "Yeah, probably."
