Strategic Mating Partner Chapter 19

Sejin’s face turned bright red in an instant as he flared up with anger, and Taehyun, unable to hold back, burst into laughter while pulling Sejin into an embrace.

“Seriously, come on…!”

“Ah, hah, sorry, hahaha, I, ugh, I didn’t know you’d hate it that much.”

Seeing Taehyun practically choking with glee, Sejin felt like everything he’d been holding back exploded in a single moment. Here he was, worried that Taehyun might get hurt, and this guy was cracking ridiculous jokes? Taehyun laughed so hard that his erection, which had been poking at his stomach, softened halfway, and with a hic, he finally calmed down. Looking at Sejin, whose face was as red as if it had been doused in crimson paint, made Taehyun feel so good that his petty worries didn’t even cross his mind.

“What’s got you so upset? I said if you put it in and I die, I’ll leave my entire inheritance to you.”

Still teasing, Taehyun’s words prompted an immediate retort from Sejin.

“No thanks. Stop saying weird stuff….”

“Ohh, you don’t need it? I’ve made enough money now? Oh, right, with your grandfather around, money doesn’t work anymore, huh?”

The tone, light as if they’d gone back four years, made Sejin huff and turn his gaze away. Taehyun, finding Sejin’s reaction unbearably cute, cupped Sejin’s cheeks with both hands, making him look up.

“Alright, I won’t tease anymore, so just put it in already.”

Then he lifted his hips and climbed back onto Sejin’s lower abdomen. With that kind of girth, it was bound to hurt, but the earlier commotion had somehow made it feel okay. As the tension eased, Sejin, still cautious, placed his hands on Taehyun’s waist. Even Sejin couldn’t hold back any longer.

“Got it.”

Finally, he slowly pushed his rigid, condom-covered member toward the folds, and the hole, which had been stretched by fingers moments ago, began to open slightly. Was it really supposed to be this tight? As the tip of the glans was gripped snugly, Sejin hurriedly took a breath and held it. The sensation was far more intense than he’d expected. Even through the condom, he could feel the rippled texture of the inner walls, leaving him flustered.

“Ah, wait, just a second.”

The inner walls clamped down so fiercely from the start, as if they’d swallow the glans whole, that Sejin instinctively tried to pull back. But his efforts didn’t come to fruition. Taehyun urgently grabbed Sejin’s wrist.

“No, just keep going. It’s, ah, the hardest when you’re just starting to push in….”

Stopping Sejin in a hurry, Taehyun’s earlier ease was gone, his face now contorted. If you had to categorize it as painful or not, it was definitely painful. But it wasn’t the sharp sting of a cut or the sensation of flesh tearing. Having never used his rear to satisfy his urges alone over the years, it was practically a virgin passage, so there was no way it could easily accommodate such a massive size.

As the ferocious girth suddenly forced its way into a tightly closed passage, it felt like the organs in his lower abdomen were scrambling in shock. Was this okay? Taehyun himself felt a sense of crisis, but the glans had already pushed its way in. If it hadn’t torn by the time the ridge of the glans was inside, it meant no blood would be shed. Gritting his teeth against the pressure that felt like it might pierce his stomach, Taehyun exhaled.

“It’s better to push it all in quickly and let me adjust.”

Urging Sejin based on his limited experience, Taehyun watched as Sejin nodded with a tense expression. It was oddly pleasing, in the midst of it all, to see readable emotions on the face of a guy whose thoughts were usually so inscrutable. Could I kiss him? Wanting to soothe the startled Sejin, Taehyun felt an urge to kiss him, but the moment he realized what he’d just thought, his eyes widened in shock.

No, that’s not okay. They weren’t dating—how could he casually take what might be Sejin’s first kiss? As a flustered expression crossed Taehyun’s face, Sejin paused his advance again and asked.

“Does it hurt?”

Snapping back to reality, Taehyun shook his head.

“No, it’s fine. You can keep going.”

The discomfort, which felt like his dinner might come back up, lingered, but the pain gradually subsided, and other sensations began to fill the void. It’s because I keep getting distracted that I’m losing focus. Berating himself, Taehyun buried his face in Sejin’s nape again. The smooth, muscular skin, free of any fat, still carried a pleasant, sweet scent. Hoo. Inhaling Sejin’s scent until his lungs felt full, heat began to rise in his lower abdomen.

“Ha….”

“Not much left now.”

As Sejin said, more than half of that long member was already inside him. So this huge thing really could fit inside me. The doubt he hadn’t fully shaken, despite his own assurances, dissipated, leaving him with a strange feeling. I’m really doing this with this guy. Is this the right thing to do? As belated regret reared its head, Sejin gripped Taehyun’s hips with both hands and pressed down firmly.

“Ah…!”

The moment the massive, child’s-arm-sized member was fully thrust in, root and all, Taehyun’s back stiffened in shock at the pain of a forbidden spot being pressed, as if it shouldn’t have been touched.

“Hey, wait, just now….”

This really hurts like hell. It wasn’t just the insertion—it felt like it had hit a place it absolutely shouldn’t have. As Taehyun’s inner walls clamped down in panic around a spot no one had ever touched, Sejin misunderstood completely.

“Feels good? You just tightened so much, hyung.”

“No, that’s not….”

Tragically, Taehyun’s words didn’t get through. There was no way he’d adjusted enough to move right after such a massive insertion, but Sejin, firmly mistaken, slip, pulled out and thrust back in, hitting that painfully sensitive spot again.

“Argh…!”

Expecting near-torturous pain, Taehyun squeezed his eyes shut. But to his surprise, as he instinctively curled his hips inward to lessen the pain, Sejin hit a different spot. From the entrance, slide, the tip scraped along the folds, grazed the prostate, and plunged deeper. The breath he hurriedly inhaled was filled with Sejin’s pheromones. For a sexually aroused omega, nothing was a stronger painkiller than an alpha’s pheromones. It was as if his nerves were numbed, converting all pain into pleasure, and his toes curled reflexively.

“Ah…!”

With the inner walls clamping down as if to devour the member, Sejin exhaled a hot breath and checked Taehyun’s face. The parted lips he couldn’t close, the flushed cheeks, and the startled gaze gave Sejin confidence.

“It feels good, right? Here?”

Thrusting again while gripping Taehyun’s hips, the mere movement inside sent tingling pleasure shooting up his spine. Taehyun shook his head involuntarily. What the hell is this? He’d had fewer than five lovers, dating whoever confessed to him—omegas, alphas, betas, women, men, no preference—and this was truly a first. He’d never even imagined a member could reach this deep. Even stimulating the front had never flooded his brain with such intense pleasure.

“Wait, ha, hold on, this is weird… ah, ngh…!”

Taehyun tried to stop Sejin in a panic, but the nasal moan that slipped out told him his words wouldn’t get through. Once he started adjusting, Sejin ramped up the pace terrifyingly. The stimulated inner walls kept gushing slick, and on the now-slicker surface, slip, slide, the thick pillar slid out and thrust back in with force. Every rough insertion and friction felt like pure pleasure instead of pain, his body joyously welcoming Sejin.

“Ah, ugh… slow down, ah…! Easy, hng…!”

For Taehyun, who’d never experienced anything like this, it was almost frightening. Was this right? Was this okay? The confidence he’d had, thinking he at least had some experience with anal, felt like meaningless bravado now.

“Hyung, you seem to really love this spot. You’ve been clamping down like you’re gonna snap it off.”

Sejin responded, thrusting his hips again. Whatever Taehyun said, he showed no intention of letting up.
