Seo Ui-woo's tongue movements had become increasingly skillful as he gained more experience.
At first, he had merely licked the surface aimlessly, but now, he seemed to enjoy himself, starting from the inner thighs, occasionally nibbling, and puckering his lips like a beak to make soft, sucking sounds on the skin.
Even though it wasn't as intense as penetration, each contact was being guided, so it was only natural that he was feeling more excited.
Seo Ui-woo lifted Jae-jin's legs onto his shoulders, adjusting his posture comfortably. He grasped the soft flesh of Jaejin's buttocks firmly, pulling them apart to expose the opening more openly, then plunged his pointed tongue deep into the mucous membrane. Each lick left a trail of clear saliva, moistening the tender skin, which gleamed as it seeped out, making the area glisten.
"…Ah!"
Jae-jin flinched and jerked slightly.
Every time Seo Ui-woo buried his lips deep into the opening, his ticklish hair brushed against the perineum. Additionally, he alternated between sucking and licking, exhaling in uneven breaths. Each time his warm breath swept across Jae-jin's wet skin, Kwon Jae-jin trembled, pressing his palms harder against his face to hide his expression.
A sense of unease crept in at some point as if something had gone wrong.
Peeking through his fingers, Jae-jin noticed the half-erect column of flesh. Kwon Jae-jin was slowly becoming aroused. Seo Ui-woo's attention to his rear had unintentionally stirred an erection in the front.
"It doesn't hurt. If we continue like this, it won't hurt... it's all relaxed now."
Yes, that should be enough. In a sudden rush, Jae-jin shook his head and pushed Seo Ui-woo away. Using his heels to press against Seo Ui-woo's shoulders, he forced him off. Seo Ui-woo's soft tongue reluctantly withdrew from the now fully wet opening.
"What now...?"
Panting, Seo Ui-woo looked at Jae-jin's lower body with dazed eyes. His gaze made the exposed hole twitch involuntarily. The shame of it hit Jae-jin all over again.
"All relaxed...? Really...?"
Licking his saliva-wet lower lip, Seo Ui-woo whispered slyly. Jae-jin didn't respond—he didn't have the chance. He was struggling to catch his breath when Seo Ui-woo tilted his head and pried Jae-jin's hole open with his fingers.
"Why are you lying?"
"Ah! Wait, don't!"
Instinctively, Jae-jin jerked his hips back. Seo Ui-woo frowned, clearly displeased, as if he couldn't understand Jae-jin's reaction, and thrust another thick finger inside. Earlier, it had been two fingers; now there were three. The tight sensation as Seo Ui-woo forced them in made him furrow his brow in concentration.
"Jae-jin, don't run away. It's like I'm tormenting you."
All three fingers were pushed in deeply at once, striking somewhere within that made Jae-jin dizzy. All he could do was bite his lip and endure.
"I'm doing this because of the conditions you set," Seo Ui-woo continued, unfazed by Jae-jin's groaning. Despite Jae-jin's claim that he was fully relaxed, the inner walls were still tight, and Seo Ui-woo quickly twisted his wrist, forcing his way deeper.
"Ungh, ugh!"
"Does it hurt? It doesn't hurt, right?"
"No, stop, just—ugh! Damn, ahh...!"
Jae-jin's vision gradually blurred. What had been only half-erect earlier was now fully hardened, rigid, and curved. To make things worse, clear fluid dripped from the tip of his urethra.
Beads of precum fell onto his lower abdomen, now folded as his legs were lifted, pooling at his navel and spilling over, tracing down the ridges of his abs, eventually sliding toward his chest. Despite this, the relentless thrusting inside continued, and Jae-jin realized he was in serious trouble.
"Haa, ah... ugh!"
Jae-jin went pale.
Pleasure shot up from the tips of his nerves, tingling through his fingers, toes, and head. It felt like a bolt of lightning struck his brain. His vision flickered, and at the same time, something erupted from below. Kwon Jae-jin's ejaculation splattered up to his lower chest, dribbling down his skin.
Seo Ui-woo let out a quiet chuckle at the sight.
As Jae-jin's body convulsed post-orgasm, Seo Ui-woo slowly pulled his fingers out from the now-tightened opening. His fingers were soaked and wrinkled from the wetness.
"What is this? I'm trying to loosen you up, but you keep tightening. It's like we're back at square one."
"You... you bastard... ugh, you're doing this on purpose, right?"
"You're wrong. You act like you know me so well, but this time you got it wrong."
Seo Ui-woo reached for the semen now trickling down Jae-jin's body. Since it had come from Jae-jin himself, it could be used without any concerns.
"I'm putting in the effort right now. It's not on purpose."
Seo Ui-woo collected the thick, white fluid in his palm as he swept his hand over Jaejin's chest, then brought it back to Jae-jin's entrance, letting it drip into the exposed opening. He then pushed his fingers in deeply, ensuring the fluid spread along the inner walls. Kwon Jae-jin was now completely slick, and even as Seo Ui-woo thrust his fingers in with force, the twitching hole swallowed them easily.
"I'm putting in effort so that you'll like me," Seo Ui-woo said softly.
"Hngh... ah, ugh!"
Jae-jin twisted his body, groaning in response. No matter how hard he bit his lip, he couldn't suppress the sounds spilling from his mouth. He let out a sound resembling a low animalistic cry as he tried to push Seo Ui-woo away with his foot. But, having just ejaculated, his legs were weak and limp, unable to muster the strength needed.
Seo Ui-woo, unbothered, shifted Jaejin's flailing legs to one side, gathering them together. Annoyed by the resistance, he crossed Jae-jin's knees and held them firmly in place with his left arm. Jae-jin attempted to lift his hips to free himself, but this only drove the fingers inside him even deeper.
The pleasure from earlier began to strike his brain again, and this time, all thoughts ceased entirely. His mind went blank. Saliva dribbled from his open mouth, and his throat bobbed reflexively as he gasped for breath.
"Hnngh! Hah!"
This time, it happened faster.
Seo Ui-woo quickly learned where and how to touch Jae-jin to elicit the most intense reactions. Even with his limited experience, he had already figured out the exact spot inside that made Kwon Jae-jin lose control whenever it was stimulated.
"Do you like it?"
Seo Ui-woo asked, rubbing his forehead against Jae-jin's calf as he spoke. A drop of sweat fell from his hollowed cheek. His hazy gray eyes looked at Jae-jin as if observing someone sinking into a swamp.
"It feels good, doesn't it? I've soaked you inside. See, I told you—this is a good thing. It's guiding."
Jae-jin was in no condition to answer. The overwhelming pleasure had left his brain in turmoil, causing his eyelids to tremble uncontrollably, while his nipples stood erect. He gasped, shallow sounds escaping from his throat.
"No more backtracking," Seo Ui-woo said, glancing down at the quivering Jae-jin, a soft smile playing on his lips. Despite having exerted himself with both his mouth and hands, Seo Ui-woo appeared as if he were thoroughly enjoying himself.
"I'm guiding you, Jae-jin. You're not going anywhere. You'll stay hidden here with me, sticking together until the end," he said playfully, kissing Jae-jin's calves and ankles with a lighthearted, almost teasing air.
"Got it? Hmm?"
He pressed a kiss onto the top of Jae-jin's foot with a little smack, then slowly spread Jae-jin's legs, which he had previously kept folded together. Between the slick thighs, the explicit sight of Jae-jin's arousal stood prominently, twitching slightly in the air. Seo Ui-woo's eyes crinkled as he let out a brief, admiring "Wow."
"Even without an answer, I think I know what it is."
Finally, Seo Ui-woo withdrew his hands from Jae-jin's body. Instead, he began unfastening his pants. He slid the tight belt out from its loops and undid the front of his black trousers, revealing the flushed, throbbing erection inside. It wasn't its usual color; too much restraint had caused blood to pool, leaving it an angry red, and it was already slick with moisture. The size and stickiness made it difficult to free from the fabric of his briefs and pants.
Gripping his engorged member, Seo Ui-woo paused for a moment to catch his breath. From his youthful face alone, it was hard to imagine how worked up he had become, but the state of his lower body made it clear that this wasn't something he could handle lightly. His excited gaze focused on Jae-jin as he hooked Jae-jin's legs around his waist. The tip of his swollen erection grazed the soft, swollen folds of Jae-jin's opening, and Seo Ui-woo shivered slightly, his chin trembling just a bit.
"Haa, ah... what... is this...?"
This was Seo Ui-woo's first time experiencing a fully lubricated "guiding." There was none of the usual friction that would cause painful tearing, nor the unbearable tightness that felt like his erection might snap. With a furrowed brow, Seo Ui-woo gripped Jae-jin's hips and pulled him in sharply. His grip was so strong it seemed like bruises might form. His thrusts were rough, with his length plunging deep inside, striking Jae-jin's core. And yet, there was no pain—only an overwhelming wave of pleasure that spread like fire.
Jae-jin gasped sharply.
"Hah! Ugh…!"
His mind, which had been halfway lost in the haze, snapped back to focus. His shoulders tensed and curled inward, while the previously relaxed folds around his entrance clenched and released sporadically. The way his body gripped and released Seo Ui-woo's length, tightening and loosening in rhythm, was maddening.
"What… what the hell is this?" Seo Ui-woo muttered, his expression tense as he thrust his hips forward more forcefully.
"What's going on inside here?"
"Hahh! I—I'm gonna… I'm gonna... no, stop, don't...!"
"If I keep going like this... I might just be able to fit it all in."
