Strategic Mating Partner Chapter 18

As Sejin slowly moved his hand to touch the folds, Taehyun’s body flinched again. It wasn’t even properly penetrated, but just the touch at the entrance made his erect member twitch with pleasure. A shiver ran down his spine from anticipation, and his thighs tensed. Sejin, admiring the sharply defined muscles of Taehyun’s parted thighs, slowly rubbed the slick that had leaked from the tightly closed entrance with his fingertips.

“Ah, ugh….”

At the gradual stimulation, as if it had been announced in advance, Taehyun closed his eyes and buried his face in Sejin’s shoulder. The skin right under his nose exuded Sejin’s pheromone scent intensely. If it were a perfume or air freshener, the concentration would’ve been headache-inducing by now, but in this moment, it was simply sweet. He was desperate to keep inhaling this scent. As Taehyun pressed his nose into Sejin’s nape and breathed deeply, the fragrance filling his lungs was utterly satisfying. But it still wasn’t enough. More, more. There was only one way to quell the growing impatience.

“Hurry up and put it in….”

It should’ve been embarrassing to get this aroused so quickly, but right now, that didn’t matter. He wanted to take Sejin inside him, to feel his pheromones in the most sensitive, tender parts of his body. As Taehyun nuzzled his cheek against Sejin’s nape, urging him on, Sejin let out a long breath and responded.

“It’s too tight. It feels like it’ll tear….”

“It won’t tear.”

Taehyun answered immediately, then, out of instinctive concern, glanced down. The erection still confined in Sejin’s pants was so massive, even pressed under the fabric, that it almost looked like an extra leg. No wonder he wore loose-fitting pants. If he wore anything remotely tight, the bulge would cast a shadow so pronounced it’d feel like he was sexually harassing everyone just by walking around. Taehyun didn’t know much, but unlike the clean-cut, two-piece taekwondo uniform, fencing gear seemed to involve multiple layers. Was that why it didn’t show? Caught in these odd thoughts, he didn’t notice Sejin suddenly slipping a finger between the folds.

“Ah.”

Startled by the unexpected intrusion, Taehyun barely had time to react before Sejin pushed his middle finger in up to the knuckle, probing the inner folds. As if searching for a specific spot, he kept tracing the soft inner walls until his straight fingertip pressed against a firm point, and in that instant, ha, Taehyun’s hips jolted without resistance.

“Ugh.”

As Taehyun reflexively swallowed a moan, Sejin looked up at him and said.

“Don’t hold back if it hurts.”

Then, as if determined, he targeted that same spot relentlessly. Already aroused by pheromones, the sensitive point being attacked caused slick to gush out from within in an instant. Taehyun didn’t need to look to know. The sensation of transparent mucus trickling down his perineum made his face burn. They hadn’t even done anything substantial yet—how could he be this aroused? Embarrassment made him want to flee, but his body wouldn’t budge. The desire to take Sejin inside and reach climax from being penetrated outweighed any urge to escape.

“Just do it already….”

Finally, Taehyun lowered his head and took a deep breath, and Sejin added another finger, rubbing inside. The heavily folded inner walls twitched, clamping down on his fingers. Sejin diligently worked to stretch the passage but still felt uneasy. It seemed to be expanding, but it was still so tight. If it gripped his fingers this snugly, could his own member even fit? No matter how he thought about it, it seemed physically impossible. It’d probably hurt too much. He had no intention of backing out now, but he didn’t want Taehyun to be in pain. Maybe he could try one more finger…. As Sejin’s movements paused momentarily, Taehyun, snap, bared his teeth at Sejin’s nape and growled.

“I said hurry up.”

Then he straightened his hips to meet Sejin’s gaze. His flushed nape and eyes, parted lips, and dilated pupils clearly showed he was as aroused as he could possibly be. Sejin was utterly pleased that Taehyun was in such a heated state because of him. To the point that, if he could bring Taehyun to climax with just his fingers without penetrating, he’d be satisfied. Of course, he’d spent countless nights fantasizing about being inside Taehyun, but the fact that Taehyun wanted him right now felt so good it was almost unreal. Maybe they should stop here for today and get tools to stretch him more next time. Feeling it directly, it seemed impossible, and as Sejin got lost in these stray thoughts, Taehyun urged him again.

“It’s gonna dry up down there if you keep stalling.”

Taehyun’s ears flushed red, perhaps embarrassed by his own words. It was gushing so much that drying up wasn’t likely, but why was it so hard to just ask him to stop dawdling and put it in? Taehyun was growing increasingly impatient. Was a male body not quite right for this? He’d thought it’d be worth trying since omegas were the same regardless of gender, but was Sejin disappointed because it wasn’t what he expected? As similar stray worries crept into Taehyun’s mind, Sejin slipped a third finger inside.

“Ah, hng….”

Then, gathering his fingers, he thrust at the same spot again. With the touch even more relentless than before, Taehyun had no choice but to cling to Sejin’s nape again.

“I said it’s too tight. Mine won’t fit in there.”

The sentence, tinged with worry and hesitation as if he’d never tried it, made Taehyun burst out laughing, pfft. Of course, with that monstrous size, it was natural to have such concerns. But thankfully, Taehyun wasn’t a beta—he was an omega. His body was fundamentally designed to accommodate an alpha’s member. He wasn’t an expert, so he didn’t know exactly how much it differed from a typical inner wall, but it was far more sensitive, built to feel pleasure easily, and had greater elasticity. A body evolved to both receive and serve its purpose being too tight to fit? Taehyun laughed as he looked at Sejin.

“Wanna bet? On whether it tears or not.”

It wasn’t the thing to say in the moment, but it seemed the best way to egg Sejin on. At Taehyun’s outlandish proposal, Sejin furrowed his brow. Yes, that’s the expression. Taehyun looked down at Sejin’s crumpled face with satisfaction.

“Hm?”

It might be a perverse taste, but Taehyun couldn’t deny it—he found it adorable when Sejin showed emotions like this. The guy who was usually so impassive, impossible to read, only showed these expressions to Taehyun. Instead of answering Taehyun’s prodding, Sejin, slip, pulled his fingers out. As the fullness left, a gush of slick followed. Careful not to let the slick on his hand drip, Sejin held his palm upward and used his other hand to pull down his pants. Thud. The elastic waistband, along with his underwear, slid down, revealing an erection so rigid it seemed it could pierce the ceiling. Though expected, the sheer volume was still shocking, and as Taehyun tensed briefly, Sejin rubbed the slick from his hand onto his member and said.

“My hands are, uh… like this… could you put it on?”

He glanced at the condom on the bedside. Taehyun nodded readily.

“Sure.”

What was so hard about that? Though not exactly skilled, Taehyun wasn’t clumsy either as he tore open the packet and slowly unrolled the condom from the tip. Sejin stared intently at his own member with a tense expression, still doubting whether it could fit in such a tight space. Who knew you could express it being your first time this vividly? Taehyun, feeling the heat below cool slightly, desperately stifled a laugh. He hadn’t expected a sexy, sultry atmosphere anyway, and it didn’t seem possible between them. With a resigned attitude, Taehyun said.

“Hey. If you put that in and I split in two.”

What the hell was he saying? As Sejin looked at Taehyun with disbelief, Taehyun grinned and added.

“My main bank account password is 4057.”

Oh, come on. It was only natural that Sejin’s brow furrowed deeply at the obvious teasing.
