The hand that had been stroking his face moved downward. It swept over his jaw, traced the line of his neck, and descended further. Bringing his thumb and index finger together in a circle, he gathered the flesh around the areola once more. The areola, protruding more than usual, looked obscenely erotic even to his own eyes. Coated in pre-cum, the light brown areola shimmered with a faint gloss.
Veins bulged prominently in the hand gripping his chest. Long, elegant fingers, their tips turning pale yellow from the pressure, repeatedly squeezed and released the breast.
“I’m telling you now, in case your mind wanders.”
“……”
“This is my first time doing something like this.”
As he finished speaking, his penis thrust deep into the gathered mound of flesh. His tongue—as it always did—pushed and bent the nipple left, right, up, and down. He grazed the surface as if teasing, kissing it with light touches before pulling away. Then, in the next moment, he buried his glans deep into the mound of flesh.
“Hah-euk! Heu! Ah… ah-eu… hng!”
He couldn’t take his eyes off it.
It was nothing short of visual torture.
The fact that his nipples were being violated not by lips, a tongue, or fingers… but by a penis.
His hips kept jerking. His back—his rear—kept tightening. He trembled from a burning sensation, unable to tell if it was the urge to urinate or sexual desire. He felt as if he might blurt out something insane, begging him to put it inside now and rub against his insides. To thrust wildly. It was terrifying. He bit down on the t-shirt he had been clutching tightly.
“Mmm. Mm. Heuu, heu… hup!”
Lee Hae-sung released the breast he had been gripping and began to rub his penis across the entire chest. From the glans to the shaft, he slid it long across the chest, savoring the sensation of the penis brushing against the nipple. The long cock occasionally failed to adjust its direction and poked Choi Hong-seo’s jaw.
“Heu-euk, heut… hup. Heuk. Heuu-heu…”
With the hem of the t-shirt in his mouth, Choi Hong-seo practically sobbed. Even though he hadn’t been touched, his genitals were standing stiff. Yet, rather than wanting his front touched, he craved the back. He couldn’t stop the motion of twisting his hips and buttocks while sitting.
The movement of Lee Hae-sung’s hips, rubbing his genitals upward, grew faster. The palm of his hand, which firmly wrapped around the back of Hong-seo’s neck to keep him from being pushed away, was damp with sweat. Everything was visible in vivid detail, even the way his urethra pulsed, leaking clear pre-cum.
“Heuuu-ng, heu-ha-eut, heuk… heu-euk.”
His moans wavered wildly, just as they did when he was being penetrated.
This is how his penis always moves inside me. Thinking that made him feel like he was going crazy. It felt as if his mind was filling with a red, hazy fog.
Unable to help himself… one hand slid between his thighs.
However, before he could reach his destination, he was caught. Lee Hae-sung hoisted the gripped wrist high. Reflexively, Choi Hong-seo lifted his chin and looked up at him. Like a child being punished, or a child caught secretly eating a cake after being warned not to touch it, he remained with one arm held high.
Tap, tap, tap.
Releasing the flesh he had been gripping, Hae-sung shook his penis, slapping it against the chest.
“Should I put it in?”
“Heuuu, heuk… heu-euk. Mm.”
Choi Hong-seo looked up at him with a pleading expression, sniffling. But it didn’t work.
“What do I do? Do I put it in?”
“Mmm. Mm. Heuu, ung.”
Wiping away tears from a strange sense of unfairness, he ended up nodding.
“Ha-eu, heuk!”
Hae-sung roughly pulled his wrist to pull him up. Since Hong-seo’s knees lacked strength, he collapsed forward, and Hae-sung caught him. In the spot where Choi Hong-seo had been sitting, the fluffy towel was damp. Looking down at it, Lee Hae-sung’s eyes grew even fiercer.
In their shower booth, various types of shower gels, scrubs, and body oils were always kept alongside lubricant. It was the same by the bathtub and in the bedside table drawer.
Picking one of the gels, Lee Hae-sung opened the cap with one hand and generously squeezed the contents onto his palm.
As Choi Hong-seo braced himself against the tiled wall, Lee Hae-sung’s hand reached in broadly from the back toward the front of his groin. A voice, low and cracked with excitement, hugged Hong-seo’s stomach and whispered in his ear.
“You’re so wet, I don’t think I even need to apply this stuff.”
Just the feeling of Lee Hae-sung’s warm, large hand stroking and gripping his crotch made him feel like he would come soon.
“Ha-euuu, heuk… heuu, hng… ha-eu.”
Wanting to resolve the simmering itch between his legs, Choi Hong-seo grabbed the long arm wrapped around his stomach and shook his hips.
“Are you rubbing yourself against my hand right now?”
Quickly, please put your cock in quickly. He felt that if he delayed any longer, he would end up blabbing something like that. Choi Hong-seo squeezed his eyes shut and bit his lower lip hard. The moment he felt the palm that had been rubbing his groin move deep toward the back, fingers dug inside.
The arm leaning against the wall trembled violently, and his head dropped.
Due to the long foreplay and the highly heightened sexual desire, Choi Hong-seo’s body was in a state of melting. His softly opened body swallowed three of his fingers with embarrassing ease. Every time the plump prostate inside was pressed, it pushed against his bladder as well, sending waves of urgency and pleasure through his lower body simultaneously. His knees naturally buckled and closed inward.
Struggling to loosen the arm around his stomach, Choi Hong-seo’s waist bent further forward, like someone complaining of abdominal pain.
“Wa-wait… just a moment, Hyung, just a moment, the back…”
“Why.”
“The fingers… I feel like I’m going to come soon.”
In other words, it was a plea to stop with the fingers and insert the penis.
Without a word, Lee Hae-sung withdrew his fingers. He had only a moment to catch his breath, freed from the excessive pleasure, before the glans began to enter, stealing his breath away.
“Ha-eu-heu, heu-euk! Ha-hu, hu… eu-ung…”
No matter how open his body was, accepting his member was not simple. Scratching at the tiled wall he clung to, Choi Hong-seo practically groaned in pain.
He could feel the inner walls twitching, clinging tightly to the glans, loosening, and then clinging again. It was like the reflexive movement of a throat swallowing food. The inner flesh of his organs was twitching and devouring the penis regardless of his will.
Hae-sung intentionally didn’t go deeper, instead pulsing in the shallow area. The distinct edge of the lower glans ruthlessly scraped against the swollen internal pocket.
Choi Hong-seo once again twisted and clawed at the firm arm wrapped around his stomach.
“Ah! Ah-eu… ah, no… Hyung, I can’t…”
“What now? You said you wanted this instead of fingers, so I’m giving you what you want.”
“That spot… that spot, it keeps… it keeps touching, Hyung…”
“Hyung, Hyung, every other word. You’re driving me crazy.”
In his ear, his voice was boiling, almost as if he were angry. Even that voice was a dangerous stimulant. It felt as if it would nudge Choi Hong-seo over the precarious line.
Lee Hae-sung’s other hand dove under the t-shirt and gripped the breast. Hot, ragged breath chewed at the earlobe, and the high bridge of his nose dug into the outer ear. Being stimulated in too many places at once, the pleasure Choi Hong-seo felt was far exceeding his limit.
“Where is ‘that spot’? Hmm? Where is my cock touching?”
The large hand gripping the breast from behind pinched the nipple. The nipple, having been tormented thoroughly, was more sensitive and swollen than usual. Using his thumb and middle finger to grip widely from the edge of the areola, he squeezed the flesh forward toward the tip of the nipple.
“Th-there… while touching there… ah-heu, ah, no… I-I don’t want to, hng…”
Rubbing his knees and thighs together, Choi Hong-seo rubbed his face against the arm holding the wall. His vision was blurred with tears. Within that blur, saliva he couldn’t swallow dripped long onto the floor.
“Do you know how much the inside twitches every time I squeeze here?”
“Ha-eut! Ha… ah-euuu, ung… heuk, heu-heuk.”
His voice, cracked and completely swallowed by excitement. Just hearing it made his stomach churn on its own. He shuddered, shrugging his shoulders and tilting his head.
His knees buckled every time the prostate was pressed deep. He felt like he couldn’t take it. The feeling of pleasure surging just before ejaculation was always similar to the urge to urinate, but today the intensity was different.
Clinging to his fading reason, Choi Hong-seo barely managed to count the foods he had eaten today in his head. Such a thing must never happen, but if, by any chance, he made a mistake in front of him… it was a terrible accident he didn’t even want to imagine…
Fortunately, because of the event today, all he had eaten all day were salads, a banana shake, and the champagne he drank at the venue.
“Ha, eu! Heut!”
The moment that thought occurred to him, the penis that had been hovering at the entrance drove straight through his organs in one go. The sensation of his rear being packed tight without a single gap by the thick shaft was truly dangerous this time. All his internal organs were being pushed out of place and crushed by his penis. The bladder was no different. Choi Hong-seo’s waist, scratching the tiled wall, sank deeply.
“Hyung… Hyung, wait… za-heu! Ha-heuk!”
To hold back ejaculation, his bare feet on the floor wiggled incessantly.
“Wait, really… can’t you just take it out for a second, Hyung?”
Lee Hae-sung didn’t answer. He simply shook his hips while chewing on Choi Hong-seo’s earlobe.
“I… 5 minutes, no, just 3 minutes… over there…”
“Over there?”
“The, the bathroom…”
“Ah…”
As if he finally understood, he let out a sound of admiration and nodded. The penis that had been filling his buttocks slid halfway out. Was he taking it out? He hoped for a moment.
“Ha-euk! Hat… ha-euuu…”
As much as it had slid out, it thrust back in all at once. Even deeper than before, the glans was pushing against the place where the front was blocked. Choi Hong-seo lifted his chin and trembled violently. That was all he could do.
To prevent him from being pushed away by the force of the penis hammering inside, Lee Hae-sung hugged Choi Hong-seo’s lower stomach tightly. Twisting his thick yet lean waist, he rubbed his penis against Choi Hong-seo’s entire rectum. Lee Hae-sung whispered in his ear like a demon.
“Sorry. Even if you feel like you’re going crazy, I’m not stopping. I. Told. You. In advance.”
“I don’t want to… don’t, heu… I don’t want this… I don’t, Hyung… Hyung, ple-please…”
He tightly gripped the wrist that was flailing backward. It was a force strong enough to leave finger marks. Their sweat-dampened skin clung to each other. Lee Hae-sung nibbled on the inside of Choi Hong-seo’s wrist. Then, he bit down hard with his teeth. Perhaps his nervous system had broken, because even that pain felt as sweet as a kiss.
