This world I was reborn into has a strangely advanced clothing culture.
For instance, underwear.
They wear modern-style bras and panties, a stark contrast to the typical attire seen in fantasy stories, like pumpkin shorts and tank tops.
I suspect another reincarnator is responsible for this shift, but...
Whoever he is, I salute you. Thank you, brother!
Now, back to the present.
Krystal's body is practically perfect—10/10 for most men, unless they prefer their women with more curves, and by that, I mean round. If you overlook the fact that she's older than civilization itself, she's quite the sight to behold.
"Do it carefully. You missed a spot."
And to that stunning figure, I... was asked to apply sunscreen oil.
This isn't limited to isekai; it's probably a dream scenario for many men. Even though we're the only two on this beautiful beach, luck has it that I can't really do anything.
After all, I'm just a kid. Four years old, to be exact.
If only this had happened in about 12 years from now instead... The circumstances might have been a bit different.
Anyway, I carefully rubbed sunscreen—which Master made herself—over her back.
Her shoulders, back, and narrow waist. The line of her spine, curved to perfection, and her nape, which is usually hidden under her long black hair. Everything about her body was picturesque.
My fingers were moving with precision, but at times, I "accidentally" moved beyond her back, touching here and there.
I'm not really sure if Master noticed it, but... since she's not really saying anything, I guess she's allowing it. Did she think it was just a kid's prank?
Of course, the thought of pushing the limits entered my mind for a moment... but the consequence otherwise scares me. Keeping to what's allowed should be good enough...
"I'm done, Master..."
After I made sure I lathered her entire back, I reported, wiping the sweat over my forehead—staining my cheeks with oil.
"Mmm..." Master hummed as she turned, now lying on her back. "Then do the front too. Make sure you don't miss a spot."
"..."
This... is she serious?
If I do that, then I would need to literally touch the two perky mountains that are covered by her white swimsuit top!
Eh? Is this fine, Master? Really...?!
"T-Then..."
Of course, with express permission, I didn't hold back. I started slow, lathering her stomach, squishy and soft. Slowly, I moved up toward her diaphragm.
Still no reaction...
I gulped as I moved further up, my fingertips pushing against her underboobs.
This... is so soft~!
It's like touching water balloons filled with warm water, without the rubbery feel!
As for her... still... no... reaction...? She's just flipping the pages of her book casually, as if I didn't even exist.
This... is Master "rewarding" me for my hard work, perhaps?
I'm not sure, but my mind's too chaotic right now. I don't know if I can hold back!
I put lots of oil on both hands and, in one go, smothered her twin peaks. I pushed from beneath and accidentally moved her top out of the way. This time, it's a real accident.
Of course, I didn't see the tip. They're currently covered by my hands, so it's safe! This is still rated for all ages... or not!
"S-Sorry, Master!" I apologized, flustered. "It's an accident, I...!"
"Mmm..."
But Master didn't even glance down, face stoic, while busy reading the book in her hand.
"It's fine, so just hurry up." She said.
Fine... what's fine? Is this fine?
My hands trembled as the two conflicting thoughts in my head debated.
Should I continue rubbing sunscreen over Master's body? But doing that would reveal her completely. Ah, but if I don't move, I'd be groping her for a long time... so soft... wait, no!
With great deliberation, I gulped hard and whispered.
"T-Then, I'll..."
I slowly fondled the peaks.
Elastic and soft. Too big for my small hands.
Ahh, I hadn't realized how close heaven was... Just an arm's length away!
As I moved my hand further back, I gulped hard and strained my eyes to glare at the stiff tips I was holding. Although I could discern their shape from touch, feeling and seeing are two entirely different experiences!
Just as I was on the verge of getting a glance of it...
"...!"
My vision went dark.
Wait, what?
What's happening?!
The sensation in my hands remained vivid—soft, supple, and elastic. But my vision had gone dark?! Was this some sort of new censorship by the FCC?!
"Cheeky kid," Master's voice echoed in the darkness, tinged with amusement. "You're too young to even feel aroused, yet you dare to lust after this perfect body of mine? You're a hundred years too early~!"
"..."
At her words, I realized something.
This darkness... is definitely the result of Master's magic.
It's a bit frustrating not being able to see, but I suppose I can manage. In fact, this situation isn't so bad after all.
Using my inability to see as an excuse, I took the opportunity to explore Master's body, rubbing against her soft skin with keen curiosity. Not being able to see heightened my other senses instead. Her flowery scent, her warmth, the sound of her breathing, and her slow moans.
I... would always remember this experience.
---
The two days of our vacation flew by quickly.
Master's routine consisted of sunbathing, reading books, and enjoying breakfast, lunch, and dinner before retreating to the hut she had set up a short distance away.
As for me?
I effectively became her hands and feet, tending to her every need.
To be honest, I was treated more like a servant than a disciple.
Still, the first day's experience was so delightful that I decided to overlook her tyrannical nature.
At night, I even got to sleep beside her... or rather, I became her hugging pillow.
It was blissful yet swelteringly hot. A woman's body is definitely warmer than a man's... I confirmed that for the first time.
Overall, the two-day-experience was neither heaven nor hell... perhaps it was a mix of both?
"Alright, we'll be returning. Come here."
And just like that, our vacation came to an end.
With a snap of her fingers, the scenery shifted around us, changing from the beautiful sunny beach to the dreary room in the Grendel Mansion's annex.
Master's outfit transformed instantly, going from her dreamlike white bikini to her usual mage robe.
For me, although my adventures had battered and torn my clothes, they got magically restored as if nothing had happened!
Anyway, now that we got back, it was time for me to receive my rewards, but...
"Welcome back, Master."
Before I could even ask, someone pulled me backward into a tight, warm embrace.
I looked up to see the flat plains—and the familiar face beyond them.
"Miranda..."
My little maid was somehow right here, waiting for us!
