Mutual Favoritism
Choi Yunjin's gaze was fixed on the floor, trembling with unease. Despite the embarrassment that made her ears burn red, she didn't refuse. Her legs felt completely limp, making it difficult to climb onto the bed. Finally, seeing her perch her hips at the edge of the bed, Baek Donghyuk approached without saying a word.
He hadn't thought about gathering strength in his hands yet. It was closer to a desire to savor the natural response. Baek Donghyuk slowly extended his hand and placed it over the arm that was covering her chest. With a slight force, he pulled it down, bringing the swaying breasts into view.
He carefully stroked the proud breasts that had returned to their original position. The soft touch and elasticity, along with the intense stimulation of Choi Yunjin's throbbing heart, came as a strong stimulus.
“Yunjin-ah.”
“...Huh, why?”
“Truly, you're beautiful.”
“What is...?”
“The breasts I'm touching right now. Your face is cute, but why is this so mature? Honestly, I didn't know it would be this much even when you were wearing the uniform.”
“Ah, no... I, that's...”
Choi Yunjin gave up on answering and closed her mouth. She already knew that praise could be misconstrued as sexual harassment. It was just that she was curious if they had become close enough to have such conversations. And she was sure.
It's not like she's making a disgusted face.
This time, she focused her consciousness on her palm and injected a level of qi a little more than the amount she used when treating patients. This was the end of the preparation. She swept the lower part of the proud breasts as if lifting them with her fingers, and applied pressure with her palm in a circular motion over the entire area.
Since she already knew what the body wanted, it wasn't difficult. She delicately stimulated around the areola and then shifted her gaze back to the peak. The nipples that were heavily flushed were more swollen than usual. Baek Donghyuk pinched and twisted the spot with his thumb and index finger, continuing the stimulation.
“Haa! Huuu... Oppa, ah...”
“Yunjin-ah, how do you feel right now?”
“Too... strangely... good... I don't know how to explain this... Haa.”
“Then, I'll try touching you in a different position. Compare them. There's still a lot to research in this treatment method.”
Baek Donghyuk lightly pushed one of her shoulders, and with the other hand, he wrapped around her waist to turn the body's direction. As she took the position on all fours, Choi Yunjin's hips slid back. Naturally, her upper body lifted up, and her breasts slightly drooped downward, creating a perfect rear view.
He stared at the ecstatic scene for a moment, then hugged her from behind and gripped the entire breasts with both hands. It seemed no different from last time, but there was a huge gap here. The hips raised to about knee height. It was exactly touching Baek Donghyuk's genitals. If only the clothes were off, it might have been inserted directly.
“O, Oppa... N, now... on the hips... what, what is...! Hwaat!”
“In this position, you have no choice but to be in close contact to check the tension of the muscles around the pelvis. That's necessary to maintain the balance of the entire body when the large pectoral muscles relax.”
“Ah... B, but... this feeling is, huuung... too strange...”
“The body reacting sensitively is a good sign that the qi circulation is smooth. Okay, focus again. I need to give proper stimulation to the tense muscles on the chest side.”
It was a plausible statement. In fact, the areas where Baek Donghyuk's qi was injected had the effect of accurately finding and gently releasing the tense muscles, just like a professional's touch. But if the purpose was pure treatment, it would be a lie.
Baek Donghyuk pushed his lower abdomen more strongly, rubbing his genitals and kneading the breasts he was gripping with his hand. Suddenly, his head felt dizzy and his vision started to shake. Even his stomach churned. This sensation that the body's balance was collapsing clearly explained the cause.
I used too much qi...
After learning the Lust Demon's Martial Arts, he had overdone it to obtain information. Even for afternoon treatment, he should leave some. Baek Donghyuk stretched his waist as naturally as possible and loosened his wrist.
“How is it? Feeling better?”
“...M, it seems much better. Especially here, the trapezius muscle on the back of the shoulders and the deltoid connecting to the arms were always stiff, but now they're super light.”
“It's because I loosened the chest, which is the center of the upper body. Let's sit and talk for a bit more during the remaining break time.”
Baek Donghyuk extended his hand and put his arm around her shoulder. His other hand was already heading to the highly swollen breasts along the familiar path. Lightly gripping the still warm soft breasts, a subtle tremor was transmitted.
“Ah...”
Choi Yunjin let out a short breath in surprise and lowered her head. Despite repeated contacts, the atmosphere was tense. The sight was cute, and Baek Donghyuk unconsciously stroked her head. At that moment, their eyes met.
“For now, this chest can only be touched by me, Yunjin-ah.”
“W, what are you saying...?”
“If my qi blood gets twisted because I worked hard to hold it, the treatment effect will disappear. Or, the muscles might break and become even more messed up. If someone carelessly touches the delicately balanced harmony...”
“...A, okay.”
Before the obedient answer could fall, Baek Donghyuk's hand became even bolder. Now, without any hesitation, he started fondling her breasts again. With one hand, he gently enveloped the entire thing, and with the fingers of the other hand, he lightly pulled the erect nipple or touched around the areola as if tickling, playing mischievously.
“Huuet, Oppa...”
“See, if you stay tense like this, the qi blood will get blocked again. Relax and feel comfortable.”
Whether she was addicted to pleasure or truly thought her body was breaking, Choi Yunjin's submissive attitude brought immense joy to Baek Donghyuk. It had only been a month since he obtained the Lust Demon's Martial Arts. In such a short time, developing this intimate relationship with Choi Yunjin. Baek Donghyuk stared at his soft, malleable breasts being crushed in his hands for a long time.
“U, um... The break time is almost over.”
“Already? That's a shame.”
“...Then, let's see during study time, Oppa. I have to prepare, so I'll go first.”
Although her overall attitude had changed, Choi Yunjin once again left the room as if fleeing first. Even in the hallway, she carefully checked if there were any passing colleagues. Just seeing such a shy and introverted woman allow her breasts to be touched made this ability amazing. Baek Donghyuk realized anew how terrifying the Lust Demon's Martial Arts was.
Afternoon treatment time. Baek Donghyuk received the chart for a new patient. A woman in her late 40s, complaining of chronic pain in the hip joint area, had been visiting several hospitals for several months without any clear difference.
Baek Donghyuk had the patient lie on the treatment bed and, as usual, stimulated the muscles around the hip joint to check the condition. Iliopsoas, iliotibial band, gluteus medius... Since learning the Lust Demon's Martial Arts, he had only used the upper body, such as neck, shoulders, and back, so it was a bit unfamiliar.
“Does it hurt especially when you turn this leg outward?”
Baek Donghyuk held the patient's left leg and gently externally rotated the hip joint. The patient furrowed her brows and let out a small groan. It was when his touch reached the deep area where the gluteus maximus is located.
“Ah, ahh!”
Baek Donghyuk's eyes widened for a moment. Because even a slight touch caused red spots to appear immediately. It was evidence of severe muscle pain. He needed to approach carefully.
“The tension here is unusually high compared to other places. This muscle plays an important role in hip joint movement. I'll loosen it more intensively.”
Maintaining a calm voice, he carefully brought his fingers. And he adjusted the qi finely and sent it flowing. It felt like much more sensitive and delicate control was needed compared to the upper body.
Moving his hand gradually, he shifted the range and position of the red spots. How focused he was, his forehead and back were already soaked with sweat. Baek Donghyuk's heart was pounding hard. The movement path of the red spot was from the gluteus maximus to the femoral head, hip joint, and inguinal area. If he gave a little more stimulation here, it might affect even the most sensitive pubic area. For now, that's it. He was almost squeezing out all his qi, on the verge of exhaustion, and any further stimulation on the patient was dangerous.
Choi Yunjin...
What if I expand the study range? Of course, careful approach was necessary. Just like when he massaged the neck and shoulders to reach the breasts, the lower body should start within the normal range of treatment. Just confirming the possibility was satisfying.
All work finished, quitting time. Baek Donghyuk changed from the heavy uniform to casual clothes in the changing room and left the hospital building. The evening air was quite cool.
“Oppa!”
Footsteps running towards him with a familiar voice from behind. It was Choi Yunjin. Instead of the usual neat uniform at the hospital, she was wearing a light ivory hoodie and bright toned chinos. Her hair was naturally let down, and she had a light shoulder bag on one shoulder. She looked more like a fresh college student than a working adult.
“You waited?”
“...The direction is similar. I take the subway too.”
Her cheeks were slightly flushed as she spoke shyly. There was no reason to refuse. Baek Donghyuk nodded and stood side by side.
During the ride to the subway station, an awkward silence flowed, but it wasn't particularly uncomfortable. Rather, the feeling of excitement was greater when recalling the events at the hospital.
“What do you usually do on weekends? Do you have any hobbies?”
As they sat side by side in an empty seat on the subway, Choi Yunjin spoke first. Her voice was filled with curiosity.
“There's nothing special. Just reading manual therapy theory books and doing practice on dummies?”
“Wow... So, people who work hard are different. Amazing. If I need you... Should I do study on weekends too? Ah, no... I think it's better to have a person than just dummies...”
“As long as you're okay with me, I'm grateful. Applying it in reality is much more helpful than just selling theory.”
“Perfect, Oppa will do practice... and I will loosen the tense muscles.”
After a few more conversations, Choi Yunjin got up from her seat. Just before the door opened and she was about to get off. She seemed to be about to say something, but she just turned around.
