"Hmm... this won't do," Mu Jin said, rubbing his chin. "Sister Min Ji, the massage isn't working properly because the clothes are getting in the way. Please take them off."
"Move aside," Min Ji said, rising to a sitting position, her expression unreadable.
'Was I too direct? I need to calm her before she slaps the shit out of—'
Mu Jin was about to come up with an explanation but stopped upon seeing Min Ji's strange behavior.
She scanned the surroundings to make sure no one was around before untying her cloth belt.
The robe slipped from her shoulders, revealing her porcelain skin that seemed even smoother under the reflection of the moonlight.
She wore a cyan dudou and tight underwear of the same color that perfectly matched her beautiful blue hair. As soon as she removed the robe, she lay down again, her back facing the sky.
'I had my suspicions, but this is completely beyond what I expected,' Mu Jin gasped inwardly, his gaze fixed on Min Ji's exposed body. 'She is unbelievably voluptuous.'
While Park Nari had sculpted muscles forged in every part of her body, Min Ji was more on the curvy side. She had a peach-shaped figure, her plump buttocks being the highlight. Mu Jin was barely holding himself back from groping them.
Mu Jin was so engrossed in admiring her body that he almost overlooked the strangest point.
'I thought she would be angry. But she agreed rather easily,' Mu Jin thought inwardly. 'Now that I think about it, she didn't react yesterday when I stared at her underwear.'
Her personality confused Mu Jin. She would get embarrassed for a minor reason like sharing the same chopsticks but was completely fine showing her body.
'Is she an exhibitionist?' Mu Jin shook his head, putting the thought aside and focusing on the massage again.
Now that there was no cloth barrier between them, the moment Mu Jin grabbed Min Ji's thighs with his fingers and began the deeper movements, the reaction was completely different from before.
"Hnnggg~~" Min Ji moaned, tightly gripping the robe beneath her with both hands.
For the next five minutes, Mu Jin massaged every nook and cranny of her back where he had spotted the marks, deliberately leaving her butts untouched.
With each press of his fingers, Min Ji couldn't help but release ecstatic moans, her whole body shivering under an unknown pleasure.
'Let's see how far she will let me go,' Mu Jin grinned, slowly moving his thumb upward along the inner side of her thighs.
"Sister Min Ji, would you like to feel even better?"
"E-even be-better than this?" Min Ji asked, her breathing uneven.
"Yeah, you will feel something you have never felt before," Mu Jin said, reaching the end of her thighs, his thumbs brushing against the cloth of her underwear.
From the moment Mu Jin began massaging her, Min Ji had been experiencing a tingling sensation between her legs, and it only intensified when he touched her bare skin directly.
Mu Jin could already see her underwear dampened and clinging tightly to her little sister.
"I have your permission then," Mu Jin said, pushing his thumbs inside her underwear.
"W-wait, Mu Jinnnnnn~~" Her resistance turned into a moan of ecstasy as Mu Jin began pressing the outer skin of her lower lips.
Mu Jin didn't touch her pussy. He kept tormenting her, touching only the outer boundary, moving below before massaging the skin inside her underwear with his thumbs again.
"Sister Min Ji, were you saying something?" Mu Jin asked, his voice laced with innocence.
"I..I was saying you aren't massaging me properly," Min Ji murmured in a low voice. "You keep missing one part."
"Which part, Sister Min Ji?"
Min Ji moved her hand behind her back and whispered, touching her dampened lower lips, "Massage me here as well."
"But there is a cloth covering that area."
"Just take them off—"
Min Ji's words came instantly without hesitation, and Mu Jin's hands moved even faster. She hadn't even finished speaking before her underwear was already flying through the air.
"Kyaa!" Min Ji exclaimed, flinching from head to toe.
"What happened, Sister Min Ji?"
"N-nothing. I was just surprised. You are so fast at removing clothes."
Mu Jin didn't reply. His focus was completely fixed on something else.
Now that her ass was fully revealed, Mu Jin realized that...
She was thick.
Just yesterday he had been staring at her butts from a distance, but now he could not only see them in their full glory but also grope them to his heart's content.
The thin line of her pink vertical lips below her round mountains, glistening with her love juices, looked equally enchanting under the moonlight.
Mu Jin didn't waste another second. He grabbed her cheeks with both hands, his fingers digging into her soft skin, molding her ass into different shapes as he began groping them.
"Aahnn~ a-amazinggg~ y-your massage is amazing, Mu Jinnn~" Min Ji whimpered, her voice breaking with pleasure.
'Hehe, she has completely lost it,' Mu Jin chuckled inwardly, the corner of his lips rising.
'Now should I do that or not?'
Mu Jin gave the idea a deep thought for one second before declaring inwardly,
'Hah, of course I should. A man should always take the risk.'
With that, he moved his thumbs into her valley and spread her cheeks apart, revealing what had never been shown to anyone before.
The cold night air touched her little pink star, making her whole body tremble. At that point, her mind was too fogged to resist anything.
'Wow, both of her holes look so erotic,' Mu Jin gasped, a drool leaking from the corner of his lips.
This was the final test of the waters. Since she didn't oppose even this, Mu Jin was obviously not going to stop here.
He continued massaging her butts with one hand and moved the other below, his middle finger gently brushing the thin line of her wet erotic lower lips.
