Chapter 65: Gradually Being Stained
Chapter 65: Gradually Being Stained
After finishing such a satisfying meal.
We left the restaurant and walked side by side down the street.
The weather was perfect—peak autumn.
It was that ideal temperature, neither too cold nor too hot, with maple trees beginning to change into beautiful colors.
In truth, the reason I had asked Auntie Seo-hyun to eat with me in the first place was that I wanted to walk the streets with her on a clear autumn day like this.
"Wasn't it really delicious?"
"Yes. The flavors were so clean and refined. I liked it."
Our hands met naturally.
Feeling the cozy warmth transmitted through our interlaced fingers, we leisurely made our way toward our next destination.
Since we’d finished our meal, it was time for dessert.
We picked up a gelato each from a dessert shop near the restaurant. As we walked along the trail, taking bites one by one, a sense of peace suddenly washed over me.
Glancing over, I saw Auntie Seo-hyun eating her gelato with a look of pure satisfaction.
…Had we ever been this relaxed before?
Since we usually spent our time together in animalistic sex, intensely craving each other’s bodies, this leisurely time spent together felt even more special.
Physical intimacy is important, of course, but spending time like a normal couple is also crucial—
Vrrrrrr…
"Haah, ahh…"
Ah, right. I forgot I’d put a dildo in her.
Seeing Auntie Seo-hyun sweating profusely, her face flushed bright red as she let out a small, stifled moan, I realized she was barely holding it in.
"Are you okay?"
"……Yes. Master. I’m fine♡"
Her voice was thick and sticky, laced with a slight breathlessness.
She said she was fine, but the fact that she suddenly used the title 'Master' meant her arousal switch had already been flipped halfway.
As proof, a look of lewd desire had surfaced on Auntie Seo-hyun’s face, and I could faintly smell the pheromones of a female in heat radiating from her.
I secretly squeezed her butt and whispered.
"Can you hold out?"
"Yes♡ I can handle this much♡"
The corners of Auntie Seo-hyun’s mouth curled up.
Her expression was filled with a sense of thrilling excitement.
"If anything… it’s incredibly arousing♡"
"Heh. Just wait. Once this date is over, I’m going to fuck you until you pass out."
"Yes, Master♡"
Auntie Seo-hyun’s voice was thick with affection for me.
We continued our walk, holding hands tightly. As we reached the end of the trail, a sign on the corner caught my eye.
[NAIL & Beauty]
It was a nail salon.
Through the glass window, I could see neatly arranged tables and several staff members busy working on customers' hands and feet.
"Oh, there’s a nail salon."
"You’re right. It looks busy."
Auntie Seo-hyun glanced at the window and lightly touched her fingertips.
Her bare nails were only clear-coated for maintenance.
They were healthy and pretty, with a faint pinkish hue showing through, but they had no color on them at all.
While her bare nails were beautiful enough, for some reason, I felt a sense of lingering regret.
"Do you not usually get nail art done?"
"It just chips off immediately when I’m working at the cafe. And... my husband said his preference is for me not to do nail art, so I just naturally stopped doing it."
"Well, my preference is for you to have it done."
The honest sentiment slipped out of my mouth.
Her fingers were so long and white; adding just a bit of color would make them stand out and look much more beautiful.
The shape of her nails was lovely, too, so I figured almost any color would suit her.
Moreover, hearing that she hadn't done it because it was her husband's preference made me want to stain Auntie Seo-hyun with my own tastes even more.
"If that’s what Master wants, I’ll do it right away♡"
"Then let’s do it."
We walked straight into the nail salon.
As we entered, the air—a mix of subtle lotion scents and the distinct smell of nail polish—hit us.
A staff member approached us, and when we mentioned she didn't get her nails done often, she began explaining various options.
"We have gradients, glitters, and designs with parts attached. We also have simple, solid colors… and many people like to get a matching set for their hands and feet."
"My feet too…?"
Auntie Seo-hyun’s shoulders flinched slightly.
The staff member continued with a soft smile.
"Yes, we do pedicures as well. If you take care of both your hands and feet, it feels great when you wear sandals or even when you're barefoot at home. If you have time today, would you like to try your feet as well?"
"Should I do my feet too…?"
Auntie Seo-hyun trailed off cautiously, glancing toward me.
I answered without hesitation.
"It’d be a shame if only your hands were pretty."
"Okay. I’ll do my feet too, then."
"Your boyfriend certainly has clear tastes."
The staff member said this, assuming we were a couple, and Auntie Seo-hyun let out a little chuckle as if she enjoyed hearing that.
"What color can I help you with? Is there a specific color you’d like?"
As she spoke, the staff member brought over a color chart. She looked at Auntie Seo-hyun’s long, white fingers and continued with a voice full of admiration.
"Your nail shape is so pretty that I think anything would look good on you. Is there a particular color or vibe you’re looking for?"
"Hmm. I’ll go with whatever my boyfriend wants."
Saying that, Auntie Seo-hyun looked at me as if she were leaving the choice entirely up to me.
I stared intently at the color chart the staff member held out, trying to pick a color that suited my taste.
As I wondered what color should stain Auntie Seo-hyun’s fingernails and toenails, one specific slot among the countless colors stood out vividly.
A deep, glossy black.
"How about that one?"
The staff member tilted her head at my choice.
"…Black?"
It was a total, pitch-black.
A deep black that looked as dizzying and dangerous as a venomous snake.
It was intense, but I liked it because that dark color seemed to represent Auntie Seo-hyun’s descent into corruption.
"Are you sure? It might look a bit strong…"
At the staff member’s slightly worried remark, Auntie Seo-hyun gave a sultry smile.
Then, she answered very clearly.
"It’s fine. I like that color too."
A deep, glossy black.
Having chosen to have her fingernails and toenails painted in that solid color, Auntie Seo-hyun’s eyes shimmered with anticipation for the transformation she was about to undergo.
.
.
.
The manicure and pedicure were finished.
I looked at Auntie Seo-hyun’s hands and feet.
At the ends of her long, slender fingers and toes, the deep, dark black nails sat vividly.
Like black pearls shining in the dark.
Simply calling it 'pretty' wasn't enough; there was a dangerous, dizzying atmosphere about it.
"Wow… it really suits you."
The staff member was the first to exclaim in admiration.
"Maybe it’s because of your fair skin, but the black makes your hands look even longer. Plus, the vibe is completely different."
"Really? Do I look that different?"
Auntie Seo-hyun looked satisfied as well.
She wiggled her black-stained fingernails and toenails, then gave me a bright smile, clearly pleased with her new look.

It was a very satisfied eye-smile.
I was also pleased with the result.
"I’ll pay now."
It happened while I was paying.
Without realizing it, while searching for my wallet, I accidentally pressed the button on the remote control connected to the dildo.
Vrrrrrrrrrr—!!!
"Hnghhhhh!!?"
The dildo’s vibration suddenly intensified.
Startled, Auntie Seo-hyun hurriedly bent her waist.
"Ugh♡!?"
She barely managed to cover her mouth and hold back a moan.
Up to that point, it wasn't really a big problem, but the issue was what happened next.
The anus is, by nature, an exit.
As her sphincter tightened, the dildo inside couldn't withstand the pressure and began to slide out. Suddenly, something thick and bulky protruded against the fabric of Auntie Seo-hyun’s skirt.
Fortunately, the staff member was in front of us and didn't see the bulge appearing at Auntie Seo-hyun’s backside. She quickly reached behind her and shoved the dildo back into her anus.
"Ma-ma'am? Is something wrong?"
"Oh, no. I just… stubbed my toe."
"Ah, you have to be careful. We wouldn't want you to ruin your nails or toenails."
The staff member began explaining how to maintain the manicure, but Auntie Seo-hyun could only nod with a frantic expression.
Once we left the shop and I could finally breathe a sigh of relief, I apologized to her.
"Sorry. I pressed the button without thinking."
"No, it’s okay. We didn't get caught, so it’s fine."
"But the nails and toenails really do suit you."
"Do they?"
Auntie Seo-hyun smiled and held out her hand.
The black-painted nails shimmered darkly in the sunlight.
Seeing the nails that had been a healthy pink just moments ago now stained with a black gloss that suited my taste, I felt a bulge growing in my pants.
Seeing my reaction, Auntie Seo-hyun wiggled her fingers in front of me as if she found it amusing.
"Where shall we go now, Master?"
"I don't know. Is there somewhere you want to go?"
At my question, Auntie Seo-hyun tilted her head slightly and smiled.
"Since we’ve painted my fingernails and toenails..."
Trailing off suggestively, Auntie Seo-hyun used her black-painted nails to gently scratch my lips, giving me a dizzying, provocative smile.
"Would Master like to paint my inside this time?"
Slide—
Leaning in, Auntie Seo-hyun wore a sultry smile and whispered words into my ear that were as sweet and dangerous as a poisoned apple.
"With Master’s semen♥"
