Strategic Mating Partner Chapter 21

“Haa… ha….”

Taehyun shuddered at the sensation of his own released semen trickling down his abs. As Taehyun spasmodically clenched around Sejin, swallowing him to the root, Sejin exhaled a choked breath, then hugged Taehyun tightly and spilled himself inside. Even with a condom barrier, it felt as though Taehyun was being filled to the point of distension. Taehyun flinched again, feeling Sejin’s hot temperature through the mucous membrane.

“Ha, ugh….”

As Sejin made slow, additional thrusts to empty every last drop inside Taehyun, his sensitized inner walls continued to cling to and suck on Sejin’s penis. With each repeated thrust, Sejin felt like he was losing his mind. Could it be this good? Even with the rubber barrier, the inner folds felt so vivid and clinging, constantly sucking on his penis, that it became hard again without a moment’s respite. Taehyun trembled as he felt the brief contraction and then expansion of volume.

“Wait, I just came, I’m exhausted.”

He knew it sounded like whining, but he was truly drained. Taehyun had never experienced sex this intense in his life. If it were just pain, he could endure it, but this was a different kind of agony. It was a problem of it being too good. Of feeling too much.

If his previous experiences and solo acts were a gradual warming up, a step-by-step accumulation of pleasure leading to a final release, this was just intense from beginning to end, an unrelenting onslaught of stimulation.

From the start, the level of pressure was overwhelming, making him question if this was even right, and from the middle, it felt like he was dying. He was driven to the point where his vision kept going white until he finally reached climax, making him think that if he had sex like this every day, he wouldn’t live long.

‘It’s a good thing I have good stamina.’

To think that almost 20 years of athletic training would help in this situation. It somehow felt like it went against the spirit of martial arts, but it couldn’t be helped. Thinking that his lifespan was probably decreasing in various ways, Taehyun grabbed Sejin’s penis and pulled it out of himself to escape from him. The removal itself was stimulating due to its thickness, causing his mucous membranes to twitch. Taehyun tried to ignore it as he removed the semen-filled condom, tied the end, and tossed it into the trash can near the entrance of the room. As Taehyun looked at Sejin with an expression that seemed to say, “We’re done now, right?”, Sejin feigned ignorance and asked,

“Can’t you do more?”

“What?”

Taehyun, dumbfounded, looked back and forth between Sejin’s stubbornly erect penis and his shameless face.

“You’re not satisfied with that?”

Wasn’t the penetration time quite long for a first time? Taehyun recalled his rather embarrassing first experience with penetration. It wasn’t particularly problematic, but the unfamiliar pressure made him climax much faster than when he was alone, leaving him feeling strangely embarrassed and unable to look up. Sejin, on the other hand, was clumsy in everything he did, but it took him a ridiculously long time to come.

Is this guy a premature ejaculator? If his first time lasted this long, wouldn’t he just kill Taehyun once he got used to it? Taehyun was dumbfounded that a first-timer could reach climax at roughly the same time as him, even later than him, the one being penetrated. As Taehyun waited for Sejin’s answer, still unable to hide his bewilderment, Sejin spoke with an expression that suggested it was obvious.

“Do you think once is enough? If I want to keep releasing pheromones, I need to release it all now.”

Taehyun was speechless at the confident reply. When Taehyun didn’t respond immediately, Sejin took it as a sign of agreement and tore open a new condom, bringing it to the tip of his penis.

“Put it on. You’re going to be inside me, right?”

He then made the demand while confidently stroking his penis with one hand, his demeanor so natural. Taehyun finally managed to open his mouth, which had been tightly shut.

“What, why should I…?”

As Taehyun mumbled his refusal, Sejin grabbed Taehyun’s hand and forced him to hold his penis.

“Hurry up. Shouldn’t we do it one more time before we sleep? We have training tomorrow morning.”

At the end of that shameless demand, Taehyun felt like he saw a smile he hadn’t seen before, even if only for a fleeting moment. He doubted his eyes for a second, but when he looked at Sejin again, he had his usual slightly sullen, expressionless face. Ah, something… feels off. Taehyun sighed, unable to shake off the uneasy feeling, and slowly rolled the condom onto Sejin’s penis. It was still an unreal size.

To think this actually went inside me. Taehyun’s mind wandered to the strange phrase “the wonders of the human body” and he shook his head to dispel the odd thought. Since they’d done it once, he figured Sejin could go a bit slower this time. It didn’t take long for him to realize that this was his wishful thinking.

“Ah, wait! Hey, you, uh, too fast, uhng…!”

As if proving that he had gotten the hang of it after one try, Sejin persistently targeted the same spot, as if he already knew exactly how to make Taehyun feel the most pleasure. Stop, I, hic, just, uh, just came! Reaching his second orgasm in less than 10 minutes since the thrusting began, Taehyun had to stifle a silent scream as Sejin continued to slam into him with frightening sounds, giving him no time to recover from his climax. Sejin twisted his lips and replied,

“You seem to like it fast. It’s wriggling like crazy inside. Don’t you like it?”

“Yeah, haugh…. It’s too, much, so…!”

After the second orgasm, Sejin was like a runaway truck with broken brakes. He pounded away as if thrusting with all his might was all he wanted and could do, making Taehyun feel like his insides were being shredded. The constant friction and rubbing inside caused so much swelling that now, even without any movement, just being inside him made thin fluid leak from the tip of his urethra. As Taehyun felt like he was about to die from overstimulation, he tried to subtly pull his hips back and escape, but Sejin trapped him in his embrace and buried his face in Taehyun’s neck.

“Just endure it while smelling me. You seem to really like my scent.”

What is he even talking about? Taehyun wanted to scream, but he couldn’t deny that he liked Sejin’s scent. Who knew a boy’s pheromones could be so sweet? Every time the fresh, sweet, and youthful scent filled his nostrils, his lower abdomen tingled, and instead of kicking Sejin away, he spread his legs wider to allow him to fill him more deeply.

How much longer did he thrust? As Taehyun spilled his semen onto his stomach for the third time, gasping and shaking his head, Sejin, too, seemed to be approaching his second climax as he quickened his pace. Fast pace and strong too. Taehyun’s inner thighs trembled at the intense pleasure washing over him.

“Wait, really, really can’t, ah…! Ugh, strange. Down there. Eut…!”

Even though there hadn’t been a moment to breathe until now, he had a feeling this was truly dangerous. No, I can’t take it. This can’t be okay. Taehyun clung to Sejin with his whole body as the rising pleasure threatened to suffocate him. I told you to go a little slower! At the moment his mind plunged into darkness again, along with resentment, Sejin pulled his penis out almost completely and then thrust it back in a single stroke, aiming deep. As his penis, which had been thrusting slightly off-center until now, finally hit the entrance of the soft organ inside, Taehyun convulsed, experiencing an unrelenting orgasm, as if he were designed to accept anything Sejin gave him as pleasure.

“Ah, hic, huh…. Uhng….”

As Taehyun finally burst into tears and gasped, Sejin pulled him into a close embrace and pressed his hips tightly against him. Sejin was so strong that Taehyun could vividly feel his forearm-thick penis twitching as it released semen, sending chills down his spine. His highly sensitized inner walls twitched every time Sejin’s semen spurted, filling him inside the confines of the condom.

“You really…. Eut….”

Taehyun’s eyes fluttered closed, along with a sentence filled with resentment. Sejin, instead of replying, kissed Taehyun’s sleeping face and pulled out. The evidence trapped within the thin rubber was both vulgar and satisfying.
