Strategic Mating Partner Chapter 20

Even though Taehyun’s insides ached, Sejin was still impatient with a burning thirst. Because Taehyun was positioned as if straddling Sejin, there was a limit to how much he could grind his hips. Unable to endure it any longer, Sejin abruptly supported Taehyun’s waist with one hand, lifted him up, and laid him on the bed without even removing his connected penis. Taehyun could do nothing but convulse and tremble, accepting all the stimulation as pure pleasure.

“Ah, wait, wait… just…!”

However, anyone could see that Taehyun’s reaction was one of agonizing pleasure, far from pain or discomfort. It was not enough to stop Sejin.

“You like it, right? You keep sucking on it….”

Sejin had already shifted his position for easier thrusting, lifting one of Taehyun’s legs onto his shoulder. With Taehyun’s legs spread wider than before, each time Sejin’s hips slammed into him, Taehyun’s naked penis, stiffly erect, swayed on his stomach. Sejin watched, as if not wanting to miss a single moment, as Taehyun’s penis leaked pre-cum, stood up straight, and then fell back onto his stomach.

Taehyun was feeling it with his own penis. Receiving Sejin’s stimulation, he reacted, and to avoid losing Sejin’s penis, he tightened around it, clinging tenaciously so as not to let it fall out. His thick nipples were swollen with arousal, and his well-developed chest heaved breathlessly, seeming to cheer. The fact that this erotic body was now desperate for his penis made Sejin unbearably happy.

“Ah, huh, it feels, good, ah…! But a little slower….”

However, this time too, Taehyun’s words couldn’t fully escape his lips. This was because as Taehyun unconsciously tried to escape Sejin by pulling his waist back, Sejin pulled Taehyun close again, burying himself to the root.

“Ah, uhng…!”

Taehyun could no longer speak and just shook his head. Each time Sejin’s hips slammed into him, his vision went white. As expected of someone who works out, he was ridiculously strong. Of course, looking only at Sejin’s delicate appearance, the word “ridiculous” didn’t suit him at all, but to describe this monstrous strength, Taehyun couldn’t think of any other word. Does he think sex is like lifting weights? As if thrusting with all his might is all there is to it. Taehyun could do nothing but gasp as Sejin put his weight into each thrust, aiming for a deeper connection.

“Sejin, ah, ugh, Joo Sejin…!”

Finally, Sejin’s thrusting stopped only after Taehyun’s name escaped his lips. Did it hurt? As Sejin’s face turned pale and he looked at Taehyun, Taehyun, having finally regained his composure, caught his breath and spoke.

“A little, ha, slower…. Slower.”

At Taehyun’s barely uttered sentence, Sejin’s eyes widened, and he asked urgently,

“Did it hurt? If it hurts, you have to tell me….”

“No, it doesn’t hurt, but…”

Ah, shit. Somehow, I don’t want to tell this to the guy who just lost his virginity in my hole. Taehyun cleared his throat, pretending to be distracted, and then muttered,

“Yours is, yours is too big…. Just putting it in, it presses against me so much, the stimulation is too intense….”

Unable to bring himself to say that it felt too good, he mumbled evasively, and Sejin’s eyes widened again. So, in the end, it meant that it was too good, too overwhelming. Just as Sejin was about to ask again, Taehyun covered Sejin’s mouth first.

“Do it slowly, I’m not running away.”

Of course, he half wanted to run away. He was enduring it only because of the Olympics, a line in the sand he couldn’t retreat from. If it weren’t for that, he might have given up, saying it was too much. Taehyun had never been so grateful for his resilient and sturdy physique. He used to think the most grateful moments were when he could endure a few hits during group punishments and just defy them, but things had turned out this way. He was so dumbfounded that he couldn’t believe it. Sejin looked down at Taehyun for a moment at his words, gulped, and nodded.

“Okay. I’ll do it slowly.”

And then, really slowly, he pulled his penis out, letting Taehyun’s inner walls stretch, and then gently slid back inside. Although the force was weaker than before, Taehyun still struggled to maintain his composure due to the feeling of fullness. Each movement felt distinct, different from the rough thrusting, causing a constant tingling in his lower abdomen.

“Ah… Huh, uhng…”

A different kind of pleasure washed over him, and Taehyun pulled Sejin closer, wrapping his arms around Sejin’s neck. As the distance between them closed, the scent of Sejin’s pheromones intensified. Taehyun buried his face in the crook of Sejin’s neck and behind his ear, places where his scent lingered, and inhaled deeply. He had nothing to say if someone called him a pervert, but from earlier, this sweet scent had been so intoxicating that he couldn’t think straight. In the process, Taehyun’s lips unintentionally brushed against Sejin’s soft skin, and for some reason, it felt as though Sejin’s penis had grown even larger.

“….? Why is this getting bigger…?”

Taehyun was startled, his eyes widening as he pulled back to look up at Sejin. Sejin’s face had flushed crimson again.

“This is your fault.”

“What?”

Taehyun couldn’t understand what Sejin was talking about. What did I do? Did I kiss him, did I suck on him? Huh? His head tilted in confusion, but before he could react, Sejin spread Taehyun’s thighs again, pushed deeper inside, and then bit and sucked on Taehyun’s neck. What is this? Is this supposed to be payback? Whether Taehyun was flustered or not by the inexplicable action, Sejin continued, licking his way up Taehyun’s smoothly exposed collarbone. He lightly sucked on the flesh where the scent was erotic, and the resulting tremors were transmitted directly to him. When he only smelled it, there was no impression of sweetness at all, but on his tongue, it was so sweet it was intoxicating. Sejin didn’t want to tear his tongue away from Taehyun’s skin.

“Ah, again, haht, what….”

Taehyun squirmed, struggling to escape from Sejin’s embrace, but his body went limp. The exploration and sucking of every part of his body was strangely stimulating. In addition, the gentler thrusts were perfectly tuned to Taehyun’s pleasure, accumulating a comfortable, non-overwhelming sensation. He was already on the verge of climax.

“Ah…! Wait, I’m, almost….”

Taehyun tried to push Sejin away due to the imminent feeling of orgasm. To cum faster than the guy who was doing this properly for the first time. And he wasn’t even the one doing the penetrating, he was being penetrated. He felt embarrassed that he had tried to take the lead as the more experienced one between them. As Taehyun fidgeted and twisted, Sejin held him firmly, refusing to let go.

“No, hold on a little longer.”

And then, deliberately, Sejin thrust his hips hard, as if digging into the spot where Taehyun felt it the most. With the pace increasing again, Taehyun lost his mind and gasped, breathing rapidly. The room was filled with the scent of a rutting alpha, and every breath Taehyun took was filled with Sejin’s pheromones.

“Uhng, ha, ugh, I can’t, anymore…. Ah…!”

As Taehyun shook his head in agony, Sejin interlocked his fingers with Taehyun’s and gripped his hand tightly. The warmth transmitted through his palm was damp. As climax approached, fluids gushed out, soaking the area beneath his hips. Each time Taehyun’s slick bodies collided, a lewd, slapping sound echoed. Was sex always this intense? Taehyun looked up at Sejin with unfocused eyes. He felt the urge to kiss Sejin’s slightly parted lips, which were tight with tension.

But it felt wrong. Leading him on without any intention of taking responsibility. He shouldn’t do that, especially to Sejin. He had agreed to be partners because he believed Sejin wouldn’t fall for him. Taehyun regained his composure and bit his lip.

“Joo Sejin, now, uhng….”

As Taehyun moaned Sejin’s name, as if he truly couldn’t hold on any longer, Sejin pulled Taehyun’s legs close, rocking his hips and replying,

“Yes, I know. Ugh….”

And then, the moment he thrust into Taehyun’s core with a thud, Taehyun came, a powerful orgasm unlike any he had ever experienced, spilling onto his stomach. The semen pooled thickly in the grooves of his abs. His slick hole naturally tightened, his inner walls clenching around Sejin’s penis with a force incomparable to just moments ago. There was nowhere to escape the pleasure that consumed his entire being. It was a pure sensation, as if they were the only two left in the world.
