Chapter 5: Choi Yunjin's Breasts
Baek Donghyuk's fingertips slipped into the narrow gap between Choi Yunjin's side and the treatment bed. It was a sudden intrusion. Through the fabric, she felt an unfamiliar sensation and drew in a sharp breath.
“⋯ Wait a moment, oppa!”
“Huh? Your muscles are really tight, Yunjin-ah. I'll loosen them up right away.”
His low voice echoed beside her ear. Before his hand even made contact, a thrilling tingle raced through every nerve in her body.
‘I’ve never imagined anything like this before⋯. A man’s touch⋯ touching my body so directly⋯ I never thought it would feel like this⋯.’
In an instant, her mind went blank. Baek Donghyuk’s entire palm finally gently encircled the sensitive area just below her breasts. The heavy weight and warmth were transmitted directly. Even though he was only supporting them, her heart raced as if it would burst. She buried her face in the bed and panted heavily.
How was she supposed to react? This was clearly beyond the scope of “study.” The fact that she was having such intimate contact with a man—her oppa who worked at the same hospital—felt completely unreal. Yet she couldn’t push his hands away. No, she didn’t want to. She had already become addicted to the indescribable thrilling stimulation.
Baek Donghyuk’s thumb began to draw gentle circles on the tender skin just below her breast.
“Ha-eut⋯!”
Her waist arched slightly.
“Are you okay? You must be in a lot of pain⋯. Hoo, take a deep breath.”
Something far more intense and deep than the pleasure she had felt earlier surged from deep in her lower abdomen. It felt as if all the blood in her body was rushing to that single point where his fingers moved. Her face burned with embarrassment, yet at the same time, the overwhelming sensation she had never experienced blurred her sense of reality.
‘Oppa’s touch⋯ is too much⋯. But I don’t want to stop⋯.’
Baek Donghyuk’s fingers were relentless. The circling motion stopped, and this time he pressed firmly on the exact spot with clearer pressure.
“Huuuick! Ah, oppa⋯!”
A short cry escaped with his name. It was as if the blocked vessels had burst and hot energy flooded her entire body. Her hands clutching the bed sheet tightened on their own. The thought of resistance had long since faded. ***
Baek Donghyuk focused on Choi Yunjin's trembling voice and rough breathing. Even though he had only stimulated the lower part of one breast, the reaction far exceeded his expectations. His own heart began to race rapidly.
‘If the reaction is this much⋯ maybe a bit more⋯.’
Not only her right breast, but also around her left breast, faint red dots appeared in his vision, flickering as if urging him to stimulate them harder. One wasn’t enough. Baek Donghyuk was swept up in the intense impulse to caress both at the same time.
“Yunjin-ah, I’ll change your position for a moment. With this angle, the force isn’t entering properly.”
He whispered softly into Choi Yunjin's ear while she lay prone and panting. It was an excuse. But his voice carried a subtle confidence it had never possessed before. Instead of answering, Choi Yunjin nodded with fluttering eyelashes.
Baek Donghyuk carefully climbed onto the treatment bed. Kneeling between Choi Yunjin's legs, her plump buttocks pressed against his thighs. As he moved, her hips swayed slightly and a short moan escaped, but he could tell it wasn’t unpleasant. Rather, her buttocks clinging to his thighs seemed to heighten her excitement from the bold action.
This position was perfect. By leaning his upper body forward to lightly press on both of Choi Yunjin's shoulders and control the movement, he could freely bring both hands to her breasts. Baek Donghyuk no longer hesitated.
He wrapped both hands around the two protruding mounds over her uniform. The sensation in his palms was much softer and fuller than expected. When he gently squeezed, the soft elasticity was fully transmitted. The direct touch, unlike before, made Baek Donghyuk's breathing roughen. This was his first conscious act of caressing a woman's breasts.
“Ha-eut⋯! Oppa⋯!”
An unprecedentedly large and high-pitched cry escaped from Choi Yunjin's mouth. As he began to massage her entire breasts with circles using both hands, her waist curved like a bow, pressing even more strongly against his thighs. The presence of the erect nipples rising above the uniform fabric was fully felt. Baek Donghyuk, driven by momentum, used his thumb and index finger to find the prominent nipple and gently pinch it.
“Huaaang⋯! Ah, no⋯! Oppa, wait, huu-eut⋯!”
Choi Yunjin pleaded almost desperately, but her body was honest. The sight of her writhing her waist and crying out with each brush of his hand on her nipple was too lewd.
‘Truly amazing ability⋯.’
Baek Donghyuk marveled inwardly. Her body honestly reacting to every touch as if she were naked was awe-inspiring. Carefully, he pushed his fingers between the buttons of Choi Yunjin's uniform. Finally, without any obstruction, the sensation of smooth, warm bare skin touched his fingertips. The heat of her body, much hotter than expected, made his mind dizzy. Something hot surged from deep in his lower abdomen.
‘This⋯ is a woman's breasts.’
It was a fresh and intense sensation he had never felt since birth.
At the center, a nipple that had already heated up and stood erect awaited. Baek Donghyuk pressed it gently with his thumb and slowly drew circles. This time, he also put the other hand inside the uniform to start caressing both nipples simultaneously. With one hand, he gently rolled them, and with the other, he stimulated by slightly pulling them, changing the intensity.
“Uung! Haa⋯. Ah⋯! Ah, oppa⋯ there⋯! Huuick!”
Short words mixed with moans incomprehensible now came out intermittently from Choi Yunjin's mouth. Tears welled in her eyes, and her face was flushed bright red. The intense stimulation from both sides made the muscles inside her inner thighs tremble and convulse.
At that moment.
Baek Donghyuk felt a fine energy flowing from his palm and being transmitted to Choi Yunjin's body.
Was this the flow of qi from the Lust Demon's Martial Arts? Baek Donghyuk tried to concentrate and control the energy. By sensing how the strength of the qi flow affected the degree of her moans and body tremors, he could adjust it.
‘This is more than just pleasure.’
He finally realized. This ability could bring extreme pleasure to the other person, but by adjusting the intensity, it could also be applied to treatment. The stimulation being applied to Choi Yunjin now was clearly beyond the realm of treatment, at a level of pure pleasure. For general patients, such intense stimulation would rather be harmful. What they needed was 'moderate coolness' to relieve pain, not pleasure that would make them lose their mind.
‘Power adjustment⋯. Need to practice.’
While savoring Choi Yunjin's intense reaction, Baek Donghyuk analyzed the ability coldly. Her body was an ideal 'textbook' to test and train the Lust Demon's Martial Arts. He focused on the qi flow again. This time, by observing her reactions, he finely adjusted the strength of the qi to provide only the pleasure that would barely allow her to maintain her sanity.
With intentional adjustment, Choi Yunjin's reactions changed slightly. Instead of gasps that would suffocate, long, sweet sighs flowed out. The violent tremors of her body gradually turned into gentle shivers. But there was no sign of her trying to pull away from his touch. Rather, she was surrendering her body as guided by his hands.
***
Choi Yunjin, who had come down from the bed with a sway, hurriedly began to tidy up her rumpled uniform. The tips of her fingers fastening the buttons trembled slightly, and her ears, as well as her nape, flushed bright red. Baek Donghyuk couldn't bear to look directly at her face and awkwardly turned his gaze away.
A heavy silence filled the narrow treatment room. No one spoke first, and the atmosphere seemed to deliberately avoid mentioning the intense 'study' from just moments ago.
Baek Donghyuk belatedly realized that he had been too carried away by his ability and gotten too excited. In his usual self, such bold action would have been unimaginable. He started to worry about what thoughts Choi Yunjin might have, whether she might think he was strange. Baek Donghyuk cleared his throat and checked her expression.
“Um⋯ oppa. It's almost time to start the treatment⋯. Uh, I should go quickly, right?”
Choi Yunjin spoke first. Her voice trembled, but she tried to act nonchalant, chatting as if nothing happened. She hurriedly grabbed her bag and walked towards the treatment room door ahead of Baek Donghyuk.
“Uh⋯ yeah. Okay, Yunjin-ah.”
Baek Donghyuk opened the door with unnatural steps and looked at her back. The image of her body reacting hotly in his hands just a few minutes ago, and now hurriedly leaving the place, overlapped strangely. This whole thing felt novel anew. After standing there for a moment lost in thought, Choi Yunjin had already disappeared down the hallway.
