Strategic Mating Partner Chapter 42

“No, heuk…. Keep going….”

At that, Sejin nodded and smiled as if he understood. This time, he took the opposite nipple into his mouth and, very lightly setting his teeth on it, nibbled and sucked on it. Taehyun’s chest swelled and deflated repeatedly with his breaths. Sejin did not miss that opening and inserted another finger, spreading the inside. The red, wrinkled mucous membrane exposed to the air gaped open and tightened around the man’s dick. It had not even been properly inserted yet, but the way it pleaded was an utterly lewd hole.

Taehyun, without even realizing he was doing it, wrapped his entire body around Sejin. He could not come to his senses with the lewd scent filling his embrace. Sejin worked his hand until Taehyun’s hole became soft and pliable. Finally, only after the wrinkles parted and a cave-like space opened between the gaping, lewd mucous membranes, did Sejin scrape the nipple with the tip of his teeth. Taehyun went ah, sucking in a short breath as he arched his back taut. Sejin, as if stamping a mark on Taehyun’s chest, pressed his lips to it, then raised his hips and said.

“I’m putting it in now.”

Then, just as Taehyun liked, he pulled on the opposite nipple with his fingertips and went squeeze, pushing his dick against the narrow entrance. As the hard, hot head of his dick was pushed into the hole that had become soft, the already slickly wet flesh went slurp, sucking in and biting down on Sejin’s member as if to swallow it. Sejin went euk, sucking in a breath at the sudden pressure. Taehyun also, with a tremendous sense of volume that could not be compared to a moment ago being slammed into the inside that had been tantalizingly stimulated, trembled all over his body as if convulsing. Not only was there the tremendous pleasure that swallowed his entire body, but the dick, with its veins standing out, scraped against the inner walls as it entered, rubbing forcefully as if to carve its shape into the mucous membrane.

“Ah! Sejin, ah, eungh, Joo, Sejin…!”

The pleasure that rushed over him was difficult to handle, and Taehyun wanted to grab onto anything. As he gasped for breath roughly and gripped Sejin’s two arms, Sejin pressed himself tightly against Taehyun and answered.

“Kkeut…. Does it hurt? If you don’t like it, tell, me, heut…. I won’t do anything you don’t like, hyung….”

Taehyun, with all the heat in his body rushing to the top of his head, desperately held back the tears that were about to burst forth and said. Don’t like it? No way. It was the opposite. In fact, it was so good that it was frightening how he could not control his body.

“Heueu, heut, no, eung…! It’s good, ah, eu-eut….”

When Sejin pulled himself all the way out again and then rammed into him so hard his belly bulged, Taehyun could not continue his words and shook his head.

“Ah, eungh…. There, ah…!”

Perhaps a path had been cleared from having done it once. Unlike the last time, which had been overwhelming, this time there was only an overpowering pleasure as if his entire body was being swallowed. It was as if his body remembered it beforehand. How much this dick could please him. From the moment it was first inserted, his whole body cheered as if dopamine was exploding like crazy. Sejin watched Taehyun’s reaction as if to engrave it in his mind and resisted the urge to kiss Taehyun.

If he had his way, he wanted to bite and swallow the parted lips that were letting out moans. He wanted to suck up all the saliva that pooled and dripped in his mouth and cram himself into that narrow mouth. However, he could not do what Taehyun did not want, so Sejin thrust his hips so hard that a wet splish splash sound echoed loudly from below. Every time Sejin pulled out from inside Taehyun to thrust with all his might, Taehyun’s inner walls would push outwards, tightening around the shaft and seducing him. Sejin went ha, letting out a short breath before inhaling again, gripping Taehyun’s pelvis and thrusting his groin up.

“Ha, euk…. It’s good, Sejin-ah, eung…!”

Every time he did, a heated moan burst from between Taehyun’s limply parted lips. Sejin continuously gripped Taehyun’s chest with one hand. It felt spine-chillingly good how his chest twitched and trembled every time Sejin thrusted. Taehyun, without realizing it, pulled up his legs that were hanging limply downwards to spread them wider, accepting Sejin even deeper, and shook his head in the thick pleasure.

Finally, when Taehyun could no longer hold back and squeezed Sejin’s dick so tightly as if to make it burst, ejaculating a long stream onto his own stomach, Sejin too, went squeeze, thrusting deep enough to touch Taehyun’s internal organs and ejaculating a large amount of semen that could be felt from the inside. Inside the sensitized inner walls, the feeling of the dick going throb throb, shuddering and shooting semen was so vivid it was spine-chilling. Taehyun, at that thrilling stimulation, went heueu, inhaling sharply as he shook his head. The dick that had just reached its peak was already raising its head taut again.

“Haa…. ha….”

Finally, after finishing his long ejaculation, Sejin gave a few short thrusts inside Taehyun before pulling himself out. From inside the slightly swollen and parted hole, which had been holding something so big, the semen he had just shot inside Taehyun slowly trickled out. The sight of the hole, which had darkened to a crimson color, oozing the thick white fluid was more satisfying than any moment Sejin had ever seen. Sejin wiped his member on Taehyun’s thigh, which was sticky and wet with slick, then bent down and licked up the semen pooled on Taehyun’s abs.

“……!”

Taehyun, without even a moment to feel the afterglow of the extreme climax from a moment ago, was startled by the sudden ticklish sensation sweeping over his stomach and flinched, curling his body up. But Sejin was faster, pressing down on Taehyun’s legs with one arm to hold him in place.

“What now…!”

Before Taehyun could stop him, Sejin proceeded to take Taehyun’s member into his mouth. Even while doing so, his gaze was fixed on Taehyun’s face as if to pierce through him, sending a shiver down his spine. Sejin, regardless of whether Taehyun was surprised or not, sucked on the semen-stained dick with great care, as if he had no intention of stopping until Taehyun himself said he disliked it. It was not the kind of fellatio one commonly thinks of, where the throat is opened deep to receive, but literally, as if to clean the dirtied dick, he was licking up all the bodily fluids Taehyun had spilled. That rather perverted act, far from being disgusting to Taehyun, felt so sexually provocative that his hole tightened again, and he could not hide his own surprise.

“This is where… your scent is the strongest, hyung.”

It was his instinct as an Alpha craving Taehyun’s pheromones. Just like a male dog in heat would follow a female dog’s rear end and try to lick it, it was a dirty and vulgar act no different from a beast, yet it was strange that he felt pleasure instead of nausea. Sejin, seeing that Taehyun did not stop him, happily took Taehyun’s member into his mouth, went nom nom, and then licked and sucked the scrotum clean with his saliva before asking.

“Here, have a lot of other people sucked it for you?”

Taehyun went hoo, letting out the breath that had risen to his chin again and shook his head.

“No…. I don’t have… that kind of preference….”

Neither the male lovers nor the female lovers he had dated in the past had engaged in such a manic type of intercourse. The most foreplay he had engaged in was him sucking on his partner’s chest or touching their genitals with his hands. Sejin was the first one to do something this vulgar. As the end of Taehyun’s words faded away faintly, Sejin asked again.

“You said you had a girlfriend. Was she an Alpha? That person.”

Taehyun shook his head again.

“I may be an Omega, but that doesn’t mean I’m not a man.”

“……”

At Taehyun’s answer, Sejin met Taehyun’s eyes with an unreadable expression, then opened his mouth again.

“I’m curious. How you, hyung, who receives my dick so deliciously, could have fucked someone else…. I can’t really imagine it.”

As he said that, he positioned himself between Taehyun’s legs, held the base of Taehyun’s handsome member with his hand, and went nom nom, taking the tip into his mouth. Ha. Taehyun let out a hollow laugh as if in disbelief, then grabbed Sejin’s jaw with his hand and said.

“Open your mouth, Sejin-ah.”

The impulse to teach a lesson to this little brat who was treating him like a dickless hole just because he was the one fucking, arose.

🤺

“Ha, eungh….”

However, the one who ended up getting a lesson was Taehyun himself. What is this kid, really? Sejin must have also never thought a day would come when he would be receiving a man’s dick down his throat. Sejin sucked Taehyun’s dick without any hesitation. Was it because his desire as an Alpha took precedence over his physiological revulsion as a man? Even when Taehyun thrusted his groin against his narrow throat, just as he had done with his girlfriends or bottom-leaning male lovers, Sejin only had a slight blush around his eyes and seemed completely unfazed.
