Strategic Mating Partner Chapter 72

Taehyun stared at the scene for a while before speaking.

“How am I supposed to leave when you’re like this? And I can’t just go outside anyway, not with your scent all over me.”

He’d felt it since opening the door. The faint heat he’d noticed before leaving had spread through his entire body, threatening to overwhelm his senses the moment he stepped into the house. Taehyun flinched, feeling his hole tighten involuntarily, growing wet inside. At Taehyun’s words, Sejin looked at him with wet, pleading eyes and said.

“I don’t know what I might do to you, hyung.”

His hand, peeking out from under the blanket, was trembling visibly. Taehyun looked at the pale, bloodless hand and spoke.

“Just do it. It’s not like I haven’t done what I wanted. I left without even asking you.”

He couldn’t tell if this was purely guilt or if he was also caught up in Sejin’s excitement. It just… felt like he couldn’t do anything else right now. Sejin’s condition was entirely due to Taehyun’s judgment. He was just taking responsibility for the consequences he’d caused. That’s all it was.

At Taehyun’s words, Sejin looked up, startled, his eyes wide with surprise, like a rabbit. Taehyun felt an urge to poke Sejin’s flushed cheeks but barely restrained himself.

“What?”

“Do whatever you want.”

“…….”

A flicker of doubt crossed Sejin’s eyes. Was this really okay? Was Taehyun testing him? His face was full of confusion. Taehyun willingly drove the point home.

“I kept telling you. If you want something, just say it. If you’re too shy to say it, just do it…”

The sentence didn’t finish. Sejin suddenly grabbed Taehyun’s collar, pulled him close, and crashed their lips together.

“……!?”

Taehyun, caught off guard, reflexively opened his mouth. In that split second, Sejin’s tongue slipped in. It was their first proper kiss in nearly five years. Taehyun’s eyes widened in shock at the clumsy, utterly chaotic tongue work. It wasn’t just that it felt like a first kiss—it was a mess.

Sejin was jabbing at his throat with the tip of his tongue, and unable to swallow the saliva pooling in his mouth, it threatened to drip down his chin, forcing Taehyun to suck it up. Then, like a puppy, Sejin eagerly licked his lips. The most bewildering part of this chaotic mess was that, in the midst of it, Sejin’s lower half was rock-hard, whimpering as he touched himself and rubbed the tip of his cock against Taehyun, moving his hips.

‘Wow, really…’

Taehyun couldn’t help but think.

‘Like a dog…’

Not as an insult, but genuinely. It was no different from a beagle in heat whimpering and mounting someone’s leg. Though… Sejin was admittedly prettier. Taehyun squeezed his eyes shut, desperately trying not to laugh, and stared directly at Sejin, who was eagerly tangling their tongues. Perhaps because Taehyun’s gaze was so intense, Sejin noticed, narrowing his eyes to meet Taehyun’s. Realizing Taehyun was looking at him with a rather cold expression, Sejin flinched, startled, his face turning red enough to burst.

“W-what… what’s…”

Taehyun looked at Sejin, who was acting mortified, and said.

“I really wasn’t thinking anything.”

No matter how out of it Sejin was, he wasn’t going to just let that slide.

“Why, why are you staring…”

“Can’t I look? Is looking not allowed?”

He had to admit it. Seeing Sejin burning with heat, unable to relieve it, whimpering in frustration and clueless about what to do was annoyingly cute. It was undeniable, separate from the fact that Taehyun had no intention of returning Sejin’s feelings.

What was he supposed to do with this? A sigh came first. But more urgent was resolving the situation. Even if he rejected Sejin later, normalizing Sejin’s pheromone routine was his responsibility now. Noticing his own erection bulging through his pants, Taehyun said to Sejin.

“Try again. I’ll teach you how.”

Taehyun wasn’t exactly experienced enough to be a perfect teacher, but he could at least ensure Sejin’s next partner wouldn’t have to endure this disastrous yet somehow adorable experience. At Taehyun’s words, Sejin, still red as a tomato, hesitantly approached him and cautiously asked.

“Uh, how…?”

“Hmm…”

Taehyun paused, momentarily at a loss, then instructed Sejin.

“Then keep your mouth open. I’ll do it.”

Sejin nodded slightly, closed his eyes tightly, and parted his lips. Then, perhaps thinking it was only fair to look since Taehyun was staring, he lifted his trembling eyelids. His desire-soaked gaze was so pitiful that Taehyun couldn’t help but want to laugh, but he managed to stay composed.

“Hoo.”

Taking a short breath, Taehyun wrapped a hand around Sejin’s nape and lightly bit his lips. Slowly parting Sejin’s lips and touching his tense tongue, Sejin jolted, biting Taehyun’s tongue. It wasn’t hard, but it was enough to startle him.

“Ow.”

Taehyun pulled back, glaring at Sejin, who looked even more shocked and stammered an excuse.

“S-sorry, I got startled…”

Ugh, really. He’s in rut, not losing intelligence… or maybe he is? Either way, his odd behavior and awkward stiffness were so robot-like that Taehyun kept wanting to laugh. He wanted to keep teasing Sejin, but worried that Sejin’s cock, which he was diligently stroking, might burst, Taehyun silently took Sejin’s lips again and pulled off his shirt. Slightly better than before, Sejin cautiously explored Taehyun’s mouth with his tongue as Taehyun pulled down the waistband of his sweatpants.

When Taehyun lifted his hips to slip off his pants, his pheromone scent filled the air, and Sejin’s renewed excitement was palpable. Taehyun didn’t want to acknowledge it through his heavy breathing, but even that clumsiness wasn’t entirely unappealing. He willingly let Sejin’s hands roam his body. Just as their tongues parted, Taehyun was startled to see Sejin suddenly teary-eyed.

“What’s wrong now?”

And in the midst of it, Sejin was still stroking his cock like a dog in heat, making it even more bewildering. At Taehyun’s confused question, Sejin confessed like a child who’d done something wrong.

“Hyung, I want to suck your cock… but I also want to put it in here so badly…”

He rubbed the wet folds of Taehyun’s hole with one hand. Well… that’s just how human anatomy works. Taehyun, momentarily dumbfounded, laughed and answered.

“Then suck me while stretching me out.”

Pressing Sejin’s nape to guide him to his cock, Sejin took it in his mouth without resistance. Far from resisting, he looked overjoyed, as if finally getting something he’d desperately craved, licking the entire shaft with saliva. He slowly sucked the precum leaking from the tip.

Not only was he greedily sucking a man’s cock, but he’d gotten used to it, opening his throat to take the glans deeper without being taught, tightening his lips to heighten Taehyun’s pleasure. He swallowed down to the root, burying his nose in the sensitive skin and inhaling. Despite his innocent appearance, every action was so lascivious it felt perverse. His desperate need to consume Taehyun’s pheromones, as if he’d die without them, sent chills down Taehyun’s spine.

A rut really does drive people insane. Sejin was clingier and more intense than usual, obsessively fixated on Taehyun’s scent… And then Taehyun realized that even normally, Sejin had a tendency to excessively bite and suck at places like his armpits, neck, inner thighs, or perineum.
