“Ah, uh!”
“This feels better, doesn’t it? You seem to be enjoying yourself.”
“Shut up… ah!”
Tae Woon had, unfortunately, discovered the most effective way to silence Kim Sibaek. Before he could say another word, his slick, throbbing cock was engulfed once more by the hot, wet suction of Tae Woon’s mouth.
The sensation of his stiff length dragging against the roof of Tae Woon’s mouth, slipping deeper down his throat, made Kim Sibaek’s mind reel. Every jolt of stimulation was sharp, vivid, and all-consuming. If his vision weren’t blocked, he might have seen Tae Woon’s face buried between his thighs—but even imagining it made his stomach twist in embarrassment and frustration that he couldn’t actually see it.
Tae Woon sucked him like he was savoring a lollipop, lips and cheeks sealing tightly around the shaft. He swallowed the mix of saliva and pre-cum that dripped from the tip without hesitation. Kim Sibaek wanted to tell him not to do that—wanted to protest—but all that spilled from his mouth were helpless moans. He wished it would end, and yet his melting body craved more.
Sliding his mouth to the side, Tae Woon’s tongue traced the saliva clinging to the shaft. Kim Sibaek shuddered at the teasing glide, a tremor running through his spine. Only then did he realize that his underwear had vanished completely, leaving his bare ass exposed—and likely more.
“Ah! Huh, uh…”
Tae Woon’s pointed tongue flicked lightly at his perineum. The feeling of saliva trailing between his cheeks was disturbingly clear. His puckered entrance twitched involuntarily, and his hands clutched Tae Woon’s shoulders more tightly without thinking.
If Tae Woon licked any lower… if he tried to open him up—would he be able to stop him? The dangerous thought tangled in his head, the uncertainty coiling in his spine.
“Mmm.”
Tae Woon’s deep hum vibrated against his skin, his expression unreadable. Kim Sibaek could feel the slow, deliberate kneading of his muscles as Tae Woon’s fingers worked across his tense lower back.
Then came a low chuckle and the warm brush of breath against his skin.
“Relax. I won’t do anything you truly don’t want.”
At those words, the tension in his body began to melt. Kim Sibaek licked his dry lips and forced out a response, trying to sound composed.
“You already are.”
“And you like it.”
Tae Woon let out a boyish giggle, as if he hadn’t just been sucking his cock seconds ago. Then, he leaned in again. Before the saliva on Kim Sibaek’s skin had time to cool, Tae Woon’s mouth wrapped around the head of his cock once more, drawing a shudder from deep within.
His hand, which had been fondling his balls, moved in sync with the motion of his head. The earlier teasing was gone; now he sucked with clear intent. Tae Woon took him deep, all the way to the throat, where it was blisteringly hot and tight. The sensation burned through him like wildfire.
Tae Woon’s mouth pulled with force, taking him to the base. His tongue pressed into every vein along the shaft as he moved quickly, relentlessly. His vision may have been shrouded in darkness, but inside that void, white sparks of pleasure exploded. Even the faint scrape of teeth against his skin added to the stimulation, amplifying the rush of blood through his body.
“Ah, uh, ah, ah!”
If he’d had any less self-control, Kim Sibaek would have grabbed Tae Woon’s head and thrust wildly into his mouth. His hands were already buried in Tae Woon’s hair, his fingers moving almost desperately. The handkerchief tied at his wrist had long since slipped off.
Tae Woon spread his trembling thighs further apart, lifting one leg high and exposing him fully. Kim Sibaek gasped—he hadn’t even realized how open he was. The sound of his pants hitting the floor was drowned out by the wet, obscene noises of Tae Woon’s mouth at work.
Those sounds. God, those sounds. The slick mixture of pre-cum and saliva echoed with every movement, his cock disappearing between parted lips. Though he couldn’t see it, he imagined Tae Woon’s pale mouth stretched around him, spit dripping down from the corners. That vivid, depraved image seared itself into his mind.
Kim Sibaek suddenly wondered—what expression was Tae Woon making? That single thought tightened his core, and his hips jerked involuntarily. The wave of climax crept in, unmistakable and unstoppable.
“Ah, uh, Woon-ah…! I’m gonna—hurry up, move—uh, ah!”
He tried to push Tae Woon away, voice shaking with urgency, but Tae Woon wouldn’t budge. Instead, he sucked harder, deeper, locking Kim Sibaek in place.
“You, you…! What are you—ah! Ah! AH!”
Tae Woon’s throat clenched around the tip of his cock, the intense pressure demanding release. Kim Sibaek’s mind blanked out as pleasure crashed over him like a tidal wave. His body convulsed as he came, his orgasm pouring down Tae Woon’s throat.
The sound of him swallowing echoed—loud, raw, and unmistakable.
“……”
Kim Sibaek collapsed, face down on the sofa, hands covering his burning face. Shame consumed him. He had done something unthinkable with the younger brother he’d raised since Tae Woon was five. Worse still—Tae Woon had swallowed everything. Was he even human? How could he do something so perverse? Was he out of his mind?
Should he bury his face in shame and die? Jump out the window and end it all?
But while Kim Sibaek spiraled in guilt, Tae Woon hummed a cheerful little tune as he cleaned up. After airing the room and wiping down the sofa and his hands with wet tissues, he smacked his lips with satisfaction and flopped down on top of him.
“Ugh.”
A solid 0.1 tons of weight bore down on his chest, drawing a strained moan from Kim Sibaek. When they were in bed, Tae Woon usually supported himself with his arms, so Sibaek never really felt the full weight. But now, it was impossible to ignore. Tae Woon wasn’t content with just lying on top of him either—he kept pressing kisses to the nape of his neck and around his ears. The sofa wasn’t very long, so their long legs hung over the armrest, tangled together.
Crushed beneath the weight, Kim Sibaek let out a shallow breath, feeling like he might suffocate. Not that he couldn’t lift Tae Woon off him if he really wanted to—he easily could. But he didn’t move. He didn’t even try. Facing reality felt far heavier than Tae Woon’s body.
“Hyung, why are you acting like this all of a sudden?”
Tae Woon asked, already knowing the answer. He wanted Kim Sibaek to say it out loud.
“I came in your mouth. And I made you swallow it.”
Tae Woon visibly flinched at the blunt confession, falling into a short silence. After a few calm breaths, he responded with a soft, tentative voice.
“Was it really that shocking?”
“More shocking than seeing you at thirty-five for the first time.”
“Well, uh… I did it because I wanted to. I swallowed it because I liked doing it…”
“You cling to me because you want to, but I’m the older one. I should’ve drawn a clear line about what’s out of bounds.”
But how was he supposed to explain the kind of fleeting pleasure that made him lose control like that? How could he, as a human being, let something like that happen?
“Even if you had told me not to… would I have listened?”
“……”
He had a point.
Kim Sibaek turned his head slightly and shot him a glare from behind the shield of his hand. Seizing the moment, Tae Woon peppered his face with kisses. It was almost hard to believe that these were the same lips that had so eagerly taken him in just moments ago—now soft, gentle, and affectionate.
Sliding an arm under Sibaek’s waist, Tae Woon shifted their position. Kim Sibaek didn’t know exactly how much Tae Woon weighed, but together they had to be close to 0.2 tons. The sofa groaned under them, teetering dangerously. For a second, Sibaek wished it would just collapse. But instead, Tae Woon smoothly repositioned them, pulling him into a cradled embrace.
“Don’t think so hard about it. Just go with the flow. We’ve already graduated from mutual handjobs—it’s only natural to move on to blowjobs.”
In response to that shameless line, Tae Woon earned a light smack to the thigh. But then he offered what he clearly thought was the perfect solution.
“Then there’s only one answer—you should suck me off too.”
