Strategic Mating Partner Chapter 73

Well, then it might not be just a rut issue… maybe it’s just this guy’s taste. As Taehyun stared at Sejin’s face, Sejin’s cheeks flushed again, and he tightened his lips around the shaft, pulled it out, and spoke.

“Come in my mouth. I want to taste you, hyung.”

The casual way he said it made it seem like it was indeed a rut issue. Taehyun felt momentarily dizzy.

“Wait, hold on…”

But this wasn’t enough. His rear hole had been so thoroughly stimulated that the pleasure of having his cock sucked wasn’t satisfying anymore. He wondered if he should move his hips himself when, with a slurp, Sejin released the cock from his mouth and slowly licked from the tip to the base. Finding no more precum at the tip, he moved lower to the slick-drenched area below.

“…!?”

What was he doing? Taehyun, shocked by the sensation of a tongue in a place he’d never imagined anyone touching, instinctively closed his thighs. This ended up trapping Sejin’s head between them, but Sejin didn’t care and eagerly sucked the tender flesh of Taehyun’s perineum into his mouth.

“What…! It’s dirty, stop it!”

But Sejin showed no intention of stopping. He grabbed Taehyun’s thighs with both hands, lifted them with a heave, and pulled Taehyun down to lie back. Then, as if to make a point, he raised Taehyun’s hips and buried his lips in the already slick hole.

“I said it’s dirty…! Ah…!”

Taehyun’s body tensed at the strange sensation, different from any pleasure he’d felt before. No matter how he thought about it, this was weird. Why? Taehyun had never gone down on any of his female partners’ genitals, nor had his male partners done so with him. For Taehyun, who had maintained relatively straightforward relationships, this was a shocking act of intimacy. The mere fact that his dirtiest, most sensitive part was being licked made his cock throb. If Taehyun himself was a trigger for Sejin’s perverse, deviant behavior, then for Taehyun, it felt like doing something “forbidden.”

Sejin didn’t miss the chance, slipping his tongue between the folds. As his tongue prodded the soft inner walls and sucked the flesh, lapping up the slick, Taehyun’s thighs trembled. He wanted to be filled quickly. He wanted to be stuffed with Sejin, overflowing with his seed, and conceive his child. It wasn’t just an alpha’s instinct but a burning thirst for Taehyun that boiled in his chest.

“Ah, mm… Hnng…!”

As Sejin ravaged his lower parts even more eagerly, Taehyun’s abs twitched wildly. The muscles from the base of his cock to below his navel tensed intermittently, rising and relaxing. Each time, Taehyun’s erect cock, oblivious to shame, lifted its heavy mass and fell back onto his stomach. His hole kept clenching and trembling, accepting Sejin’s tongue.

Taehyun’s face burned at the sound of Sejin swallowing the slick down his throat. His hole was already fully prepared to take Sejin. Suppressing his embarrassment to the point of wanting to die, Taehyun spoke.

“Hah, ugh… Stop it. Just put it in already.”

His body was burning, teetering on the edge of climax but always falling just short. He just wanted to come. As Taehyun twitched his hips, Sejin finally pulled his mouth away from the wrinkled entrance. His face, covered in slick from Taehyun’s hole, was drenched. It wasn’t just erotic—it felt raw and primal. Momentarily speechless, Taehyun was thrown off when Sejin took his cock back into his mouth and began spreading his hole with both hands, making his head tip back.

“Ah…!”

At the same time, Sejin’s fingertips rapidly pressed and dug into a specific spot. Targeting the shallow area where the prostate was, Taehyun writhed under the forceful pressure, as if Sejin was trying to make him come. But with Sejin’s arms tightly pinning his legs, he couldn’t escape.

Even amidst this, Sejin kept rubbing and stimulating the sensitive glans with his tongue, like a cat licking its prey, pushing the lingering sensation of climax to its peak. As Taehyun clenched his hips and finally released into Sejin’s mouth, Sejin drank it eagerly, as if it were the only thing to quench his burning thirst.

Taehyun was stunned by Sejin’s lack of hesitation, sucking so desperately as if he couldn’t let a single drop spill. But what shocked him more was that Sejin had already come once without Taehyun doing anything. What? From just burying his face between Taehyun’s legs? Even in a rut, that seemed odd. Whether Taehyun felt the strangeness or not, Sejin spat out his cock, rubbed his cheek between Taehyun’s thighs, and pleaded.

“Can I put it in now?”

His semen-glistening cock was already swollen, ready to burst. If Taehyun didn’t allow it, Sejin might keep whimpering like a dog, so Taehyun nodded reluctantly. The moment he gave his consent, Sejin sat up, pulling Taehyun onto his lap. Taehyun trembled at the hard bulk pressing against his perineum as Sejin, with glazed eyes, mumbled and pressed the tip of his cock into the hole he’d obsessively licked.

“I want to come inside you, hyung. I want you to take all of me, overflowing, and get pregnant.”

With a thrust, he split the sensitive inner walls, driving in to the hilt. Taehyun, unprepared, stiffened his back and gripped the sheets at the overwhelming pressure filling him.

“Hah, ugh…”

The teasing pleasure that hadn’t reached deep enough before shot through his spine, spreading through his body. Sex with Sejin was always intense, but this sensation, pushing him to the edge, made his inner walls convulse with joy, gripping Sejin’s cock. Sejin, breathing heavily from the pleasurable pressure, whispered again.

“I want you to beg for more, hyung, to have my baby here.”

He desperately kissed Taehyun’s lips, his clumsy kissing starkly contrasting his rough thrusts. Judging by his nonsense, the rut must be severely clouding his reason. Taehyun, breathing heavily through parted lips, accepted Sejin’s tongue. Why was Sejin so desperate and pitiful? Was this just the rut’s temporary effect, or… Taehyun let out a short, bitter laugh, pressing his forehead against Sejin’s. Why did he keep wanting to tease this guy? What did he even want? He knew giving Sejin this kind of leeway would only lead to both of them getting hurt, yet he couldn’t understand himself.

“What should I do? I took suppressants today thinking of doing this with you, but I guess I’ll have to work hard enough to make them useless.”

At Taehyun’s playful words, Sejin reflexively frowned. Realizing a harsh expression wasn’t strategic, he looked at Taehyun with a sulky face and whimpered again. Instead of saying more, Taehyun spread his legs wide, taking Sejin even deeper.

“Haa, ugh… There, yeah…”

As the glans pressed against the entrance to his organs deep inside, Taehyun squirmed, his abs twitching. Sejin pressed the bulging spot with his palm.

“Here, I’ll come here, so much… I’ll fill you with the cock you love.”

Finally, like a key fitting perfectly, an electrifying pleasure surged. Taehyun’s inner walls joyfully responded, absorbing Sejin’s pheromones. Slick overflowed between their touching membranes, and with every thrust, frothy liquid spilled out. The wet, slapping sounds echoed loudly.
