Dirty Switch

It was a sensation Joo Taehyun had never experienced in his life.
As if reflecting the sudden surge of heat inside him, the shower stall fogged up in an instant.

“…What is—”
There was no point pretending not to know.
That razor-thin tension just before adrenaline explodes, the sharp spike of sensitivity rising rapidly through his nerves.

Even more so because Joo Taehyun was an Alpha with a naturally recurring rut cycle.
He had always kept it under control with carefully adjusted suppressants, but that didn’t change the fact that his body was biologically more reactive than most.
“Ah… hh…”

That was why, though rare, Joo Taehyun did sometimes feel sexual desire.
Even before he realized he liked Seo Baekhan, his heart had pounded just from the scent of his pheromones or the sight of his large hands. After his feelings had solidified, it had only become more intense.
He had never experienced penetrative sex, so he didn’t know what knotting felt like, but of course he had masturbated before.

Not that he had imagined anything dramatic. Regardless of how he felt about Seo Baekhan, they were both Alphas. It wasn’t that two men couldn’t have sex, but for some reason, he could never picture doing that with Baekhan. Well—he had dreamed once that Baekhan poked around his body, found that his waist was narrow but realized he wasn’t a woman, and left in disappointment...
Anyway, Joo Taehyun’s fantasies had always been vague and blurry. Never once had he pictured specific scenes. Just imagined hearing Baekhan say his name, recalled his pheromones. That alone made him stiffen slightly, and with a few instinctive strokes of the spongey tissue, he would release. That was all.
But the way his body was reacting now… it was completely different.

In the past, his climax had ended with a simple erection and a satisfying release—but now, his entire body felt like it was on fire. His skin prickled like something was crawling across it, and even placing a hand over those spots made his breath hitch and his upper body curl in on itself.
It felt like his body was sending him a message—something more specific was needed to ease this, and it wouldn’t stop demanding until it was satisfied.
Joo Taehyun, who had never known his body could ask for anything in such a filthy way, had no idea how to deal with it. His arm, braced against the wall, was trembling uncontrollably. Even his jaw fell slack, drool trailing down, yet his lower half showed almost no response.

He was somewhat hard, but despite rubbing and stroking, it wouldn’t stand fully erect. His mind was a mess, fogged with arousal and overstimulation, as if he had already come twice.
“Haa…”
He recoiled from the lingering water and suds that still clung to his skin, finally recalling what it was he had taken.

Ah. I took Switch. Dirty type, even.
Should he be relieved that it didn’t seem like a scam? Was it a good thing he wouldn’t have to find another one—and that he now had real evidence to show Baekhan?
And that was where the last of Joo Taehyun’s rationality reached its limit.
“…Ah!”

His legs gave out beneath him. He couldn’t stay standing. His knees buckled, and he collapsed onto the shower floor—his heel digging into the flesh of his butt, and just from that, he came violently.
Everything he’d done earlier—gripping, stroking, squeezing—had been useless, but just that jab near his ass was enough to make him spill a load, absurdly easily.
Staring blankly at the watery mess on the floor, Joo Taehyun slowly reached behind himself. ◆ Nоvеlіgһt ◆ (Only on Nоvеlіgһt) He didn’t have the courage to grab his ass or explore any deeper. He just let his fingertips touch the start of the cleft, just beneath his spine.

And just that touch made his cock spring to life again.
More than anything, it was the sensation buried even deeper—an unbearable, maddening itch inside—that truly startled him. A desperate, primal urge to shove something into that place surged forward. It felt like he wouldn’t be able to endure otherwise.
“Ha… god…”

A whimper laced with tears escaped him, followed by a bitter, breathless laugh. Fine, so the drug was real. But this was supposed to be a weak dose, wasn’t it? If this was “mild,” then how strong were the potent ones?
So real Alphas actually took this… just to bottom for another Alpha?
Joo Taehyun felt like every natural order he knew was being flipped upside down. The synthetic pleasure overwhelmed him, crashing against a wall of instinctive rejection, and yet—it felt so good, he didn’t care.

Alpha? Legal choices? Rational thought? What the hell did any of that matter? This was… too good.
To avoid stimulating himself again with his heels, Joo Taehyun shifted into a clumsy crouch—on all fours like some kind of beast. Even then, his thighs trembled and his hips twitched on their own, refusing to stay still.
He’d read that the effects of one vial lasted about an hour. So… what time was it now? When had he taken the pill?

God, the back, it’s so itchy. I hate this. This is wrong.
Stop. I don’t want to feel this way. I’m not even moving my hips on purpose, I swear, I—hate this…
As he struggled to just breathe and wait for time to pass, a thin thought slowly emerged from deep within his mind.

Then what if… what if it was Seo Baekhan who asked you to take this? What if you weren’t taking it for just any Alpha, but to take Baekhan in from behind? How would you feel then?
Would you still be able to reject this sensation?
…It wasn’t anyone else—it was his own heart asking the question. The voice of a fragile, craving instinct that wanted to completely give in to this artificial pleasure.

“…Ah, nngh…”
Joo Taehyun grit his teeth, trying desperately to endure.
I like Seo Baekhan. I like hyung. I took this drug because I like him, because I wanted to stay near him no matter what. That much is true. But, but… I never wanted to accept him like this, not in this state where I’m not even myself. I never meant to fantasize something so filthy about him. Even if I ever had to take Switch again, I swear I’ll never use the Dirty type. This is too much—I hate it. Hyung, Baekhan hyung, please… do something…

“Taehyun.”
His panting breaths stopped in an instant. The droplets that had felt like they were flaying his skin, the warm, gentle foam—none of it registered anymore. All he could hear was the pounding of his heart, filling the shower stall like a drum.
This wasn’t possible. This was Washington. His bathroom. And yet… Seo Baekhan’s voice echoed in his ears, deep and low.

“You took this drug because you wanted to do it with me?”
A long, calloused hand—those thick fingers and that broad palm—softly slid down the length of Joo Taehyun’s back. The sensation was too real to be just imagination.
Ah… So that’s why the Dirty type is classified as a narcotic.

Even as liquid dribbled from his lower half, Joo Taehyun swore to himself—he would never, ever take something like this again.
“Really?”
Even after taking the drug, Seo Baekhan didn’t show his face. He just wrapped a strong arm around Taehyun’s waist and whispered in his ear. The distance he maintained even in this hallucination was maddeningly cruel—but at the same time, it felt so real, so exactly like Seo Baekhan, that Taehyun couldn’t pull away.

“Taehyun, you’ve never even knotted before. And you’re already wet back there?”
“N-no… but I…”
As he whimpered in tears, Baekhan gently shushed him. It was a kind, coaxing tone—but not comforting. It was the tone of someone firmly telling you to get it together and do what you came here to do.

“Don’t touch yourself in front.”
Wasn’t the reason you took the Switch to get wet for me back there? Then stop touching your cock and use that hole like you’re supposed to. You’re leaking like a bitch, and you’re jerking yourself off?
His voice was crystal clear—like when he stood at the podium during Haechi meetings. Of course it was. Joo Taehyun had never seen Baekhan in an intimate setting. He had never even dared imagine how the man would speak or breathe in such a moment. So even now, the voice telling him to touch his ass instead was as composed and immaculate as ever.

“Taehyun, who are you blaming for being this filthy?”
“…Me?”
“Yeah. You even called me once, didn’t you?”

He… had? Oh, right. He had. The night before the founding ceremony, he’d called first. He remembered how surprised he’d been.
“You were getting off to my voice that night too, weren’t you?”
“No, no, I wasn’t… ngh, hyung…”

“Now that I see you like this, I realize just talking to you was enough to get you rock hard.”
Seo Baekhan—smiling as he watched him. Not scorning him for this trembling, aching body, for the rear entrance that could do nothing but clench. Not mocking the pathetic way he was falling apart.
Instead, he observed Taehyun with interest, encouraged him, tempted him. Whispered sweetly—what are you so afraid of, when one more step would bring you all the way down?

Even knowing all of this was just his imagination—
“Ah… hnngh…”
“How long are you gonna whine? Show me how you take it back there, Taehyun. For me.”

And Joo Taehyun… wanted nothing more than to obey.
He couldn’t resist.
