Im Jihyun's Breasts
Baek Donghyuk studied Im Jihyun's reflection in the mirror. The thin fabric of her bra barely contained her ample breasts, and that precarious coverage only made the sight more provocative.
Where had all that prickliness from a moment ago gone? Her eyes had gone slightly unfocused, her lips faintly parted, her shoulders rising and falling with rapid breaths. He stepped slowly up behind her. The artificial perfume mingling with the scent of sweat tickled his nose.
"Self-treatment isn't anything complicated. The most important things are precise location, the right amount of pressure, and repetitive movement."
He cupped her breasts gently over the bra. Starting from the underside—specifically the point where the flesh met her ribcage—he began applying pressure in slow circles with his fingertips. Even through the lace, the warmth of her body and the yielding softness of her skin transmitted clearly into his palms.
"We'll start with the pectoralis major. When this muscle tenses up, it restricts shoulder movement and can cause what's commonly known as rounded shoulders. Use your entire palm to press down firmly, count to five, then slowly release. Repeat that about ten times."
"...Nnh, ah!"
Each time he swept upward along the underside of her breasts and applied that gentle pressure, a suppressed moan slipped from Im Jihyun's lips. The flesh overflowing slightly from her bra swayed with every pass of his hands.
"And this area—the muscles running from the upper outer portion of the breast toward the axilla, meaning the armpit. That's the serratus anterior and part of the pectoralis minor. When these get knotted, you can get pain when raising your arms, or in severe cases a winged scapula. For this spot, using your fingertips—especially the thumb and index finger—to go a little deeper, almost like pinching, is more effective for releasing the fascia."
"Th-that's...!"
His entire palm covered her breast again from top to bottom, gripping and squeezing hard. Soft, abundant flesh with a heavy, springy weight. It was even more luscious than he'd imagined from those swimsuit magazine spreads.
"The bra makes it difficult to hit the precise locations. This treatment requires accurately identifying the origin and insertion points of the muscles and stimulating along those fibers for maximum effect. Position is critical, so it would be best to take this off for a moment."
"Haaahn! W-w-wait...! D-do you... do you even know what you're... doing right now...?"
As if he had no need to wait for an answer, Baek Donghyuk caught the shoulder straps of her bra and slid them down. Then he slowly drew the cups themselves upward.
Like peeling the skin from a ripe fruit, the lace rolled up, and her two sumptuous breasts were revealed, sagging slightly under their own weight. Pale pink areolas, and at their centers, red nipples that rose shyly, pert and swollen. He paused to admire the sight before his hands moved again.
"This is how you deliver stimulation all the way to the fascia nestled deep beneath the mammary tissue and fat layer. It may look like simple groping, but this is a process of releasing stagnant blood. A woman's breasts are particularly important pathways for lymphatic circulation, so stimulating them regularly like this is also excellent for preventing and reducing edema throughout the body."
"I-I don't give a damn about that...!"
Her eyes were already unfocused, her entire body trembling beyond her control. She whimpered in a voice tangled with rage, pleasure, and shame—then caught sight of her own reflection in the mirror and clamped her mouth shut.
One hand was mauling her breast while the fingers of the other pinched her protruding nipple, tugging and twisting. Still unable to recover from the shock, Im Jihyun squeezed her eyes shut and gasped for breath.
Ding-ding!
An alarm chimed briefly inside the room, signaling that the appointment was over. Standing before the mirror, Im Jihyun tidied her disheveled hair and straightened her clothes, her face still flushed a deep crimson. She gathered her handbag without a word and headed for the door, then shot Baek Donghyuk a glance just before stepping out. He tensed for an instant, then forced a casual expression and smiled.
"Good work today, Jihyun. The self-treatment techniques I showed you—if you try them whenever you have a spare moment, they'll definitely help. Especially for relaxing the muscles in your shoulders and back, you should feel results quickly."
"......"
Im Jihyun still said nothing. She let out a short, snorting breath and walked out of the room. The door slammed shut with a particularly loud bang.
Left alone, Baek Donghyuk let out a light sigh. There had definitely been results. The red mark had manifested on Im Jihyun's body as well, and her reaction had been every bit as intense as Choi Yunjin's. But the pattern had been somewhat different from what he'd expected. Despite following a similar process to what he'd done with Yunjin, far more energy had been consumed. He'd felt a faint resistance, as if her body itself instinctively rejected the infiltration of Qi.
Does each person have a different capacity for receiving Qi—or perhaps a kind of resistance that rejects its penetration?
He had far too little information about the Lust Demon's Martial Arts. To grasp the nature and limits of this ability, he had no choice but to infuse Qi into various people and analyze their reactions. Im Jihyun's response, so different from Choi Yunjin's, had handed him a new research subject. The thought occurred to him that there might be another possibility hidden here—something that went beyond mere pleasure.
Vrrr.
His phone vibrated briefly in his pocket. Snapping out of his thoughts, Baek Donghyuk checked the screen. A message from the team leader.
Baek Donghyuk rolled his stiff neck once and looked around the room. The bed sheet Im Jihyun had used was already rumpled, and a faint trace of her artificial perfume mixed with a peculiar body scent still lingered in the air. He gathered the used towels, aired the room out briefly, and left to prepare for the next appointment.
The burden he'd once felt with every patient treatment had vanished completely. In fact, the more he practiced treatment using the Lust Demon's Martial Arts, the more naturally his Qi flowed, and his own body seemed to improve along with it. The chronic fatigue had disappeared. He felt lighter.
After wrapping up his last afternoon appointment cleanly, Baek Donghyuk was walking down the hallway when he noticed a treatment room with its door slightly ajar. Normally he would have walked right past, but somehow he sensed a presence inside. Thinking someone might have forgotten to close it after cleaning up, he approached to shut it.
Huh?
Peering through the gap, he saw Choi Yunjin sitting on a folding chair at the back of the treatment room. She must have finished with a patient, tidied the room, and was taking a brief rest. Her head was down, her entire attention locked on her phone screen. Even as Baek Donghyuk approached with silenced footsteps, she didn't notice him at all.
Glancing over her shoulder, he saw an online shopping site. The screen was packed with colorful women's underwear—pieces with airy lace, boldly cut T-back panties, simple bras emphasizing shaping functions. Photos of every kind of lingerie were scrolling past in a rapid blur.
"Yunjin, looking to buy something?"
"Ah—!"
Choi Yunjin's cry was nearly a scream as she shot up from her seat in shock. Her phone clattered to the floor. She was so startled her face had gone deathly pale.
"...I think I was more surprised."
"O-Oppa... When did you get here? You didn't make a sound..."
She stammered in a trembling voice as she hurriedly scooped the phone off the floor. Like someone whose enormous secret had just been exposed, she hid it behind her back and smiled awkwardly. The way her ears had flushed red all the way to the lobes was adorable.
He'd already seen everything, but Baek Donghyuk pretended otherwise and sat down naturally in the chair across from her. An awkward silence filled the small treatment room, along with a subtle tension.
Choi Yunjin fidgeted, glancing at him, then carefully stood up. She walked over to the treatment room door and clicked the inner lock shut. When she came back, she hesitated in front of him for a moment, then carefully began untying the drawstring at the waist of her uniform pants.
Ssshh.
Her pants slid down weakly and bunched around her ankles. Inside them, pale apricot cotton panties wrapped around her slightly plump lower belly and the swell of her mound.
"These... I just bought them... How do they look to you, Oppa? D-do they look weird?"
"They suit you well, Yunjin. Not too mature, not too childish either. Nice and understated. They look comfortable, too."
"Then I should buy a few more similar ones. Since you said they're okay..."
Blushing even more deeply with embarrassment, Choi Yunjin was about to pull her pants back up when Baek Donghyuk suddenly reached out and yanked the elastic of her panties down to her knees in one motion.
"Kyaaah! Wh-what are you doing all of a sudden... Oppa...!"
"I've already seen everything during treatment, so what's a little teasing? Right?"
"E-even so... it's embarrassing."
"Those plump pussy lips are just too cute."
Baek Donghyuk knelt and gently traced Choi Yunjin's labia. A wet, slick sensation met his fingertips. She squeezed her trembling legs together and pulled her hips back slightly, but she didn't push his hand away. Instead, she twisted her waist ever so slightly in time with the movement of his fingers.
Aroused, Baek Donghyuk drew a low, deep breath, stood up, and pulled her nape toward him firmly. Then, without hesitation, he pressed his lips over her parted ones.
