Don't Forget What You Learned Today
I mustn't forget what I learned today. What the hell had just happened? My chest felt hollow, like the aftermath of a storm sweeping through. Not only had my breasts been groped, but now even that sensitive spot called my pussy had been toyed with.
Ye-eun had said she was teaching me how to wash myself, but even I—who'd been a guy just a little while ago—knew it wasn't anything as innocent as that. But I couldn't say a word. Instead, I'd gotten drunk on that strangely good feeling from the stimulation and let out sounds that surprised even me.
"Wh-what... is this...?"
I stared blankly at the bathroom door Ye-eun had exited through, then picked up the towel draped over my knees. First things first—wipe off and get out. The soap suds were all rinsed, so drying off would finish the bath.
I quickly dried my relatively short hair and body, then scrubbed at my pussy with the towel. Maybe this would erase what Ye-eun had done to me. But no matter how hard I rubbed, that sharp yet dull sensation from before wouldn't fade.
"Hic... I d-don't know. Just go."
In the end, I gave up, hung the towel on the rack, and stepped out.
Hye-won Kang was already outside, holding a shopping bag and chatting with Ye-eun. She must have sensed me coming, because she turned her head. Seeing me fresh out of the shower, buck naked, she smirked.
"Eww, hey. What the hell happened to you? Did you steam yourself in there or something? Your face is all red."
"Eek?!"
"Ah~. I was teaching Seo-jin how girls are supposed to wash up. That's probably why."
"Oh, really? Looks like you two were having a good time."
"It wasn't... like that...!"
I tried to raise my voice in protest, but a wave of shame crashed over me, turning it into a mumble. There was no way I could claim it wasn't some sleazy thing like Hye-won was imagining—not when that moment with Ye-eun had been anything but normal. Not only had my friend groped my breasts, she'd touched my most private spot. The real problem? I hadn't felt disgusted or resisted. I'd meekly savored the new world her fingers opened up.
If I called out Ye-eun here and blamed her for leading it, I'd just look like the weird pervert who'd gone along with it and enjoyed every second.
In the end, all I could do was play it off like it was just normal friend stuff.
"We were just bathing. Ye-eun taught me a lot... I learned tons."
"Yeah? Well, a long bath can heat up your face like that."
"Anyway, Hye-won, did you get what I mentioned?"
"Oh, that. Of course I did."
She nudged the shopping bag at her feet toward Ye-eun. Ye-eun picked it up and handed it to me.
"Here, Seo-jin. Since you're already naked, why not try on the underwear right here?"
"R-right here...?"
"Yep. Hye-won went through the trouble of getting it—gotta show her too, right?"
"U-uh... yeah, okay."
I nodded instinctively, catching the sharp glint in Hye-won's eyes, and took the bag. What the hell had they bought? Knowing these two, it was definitely something not normal.
With trembling hands, I peered inside. And when I saw the contents, my eyes widened in surprise at the unexpectedly ordinary haul.
"...It's normal?"
"Yeah, you idiot. What, you think I'd buy some perverted freak underwear?"
"Uh, w-well... yeah."
"Jeez, it's for you to wear every day. Can't have you in something like that. These are practical for daily use, so wear 'em."
The underwear Hye-won brought was surprisingly plain. Everyday designs you'd see blatantly displayed in street lingerie shops. The black ones with lace trim at the edges felt a bit sexy, but otherwise, they were just... underwear. Nothing special.
"Alright, try 'em on. You gonna stay naked in front of your friend like that?"
"Uh? N-no, of course not!!"
"Thought our Seo-jin was a perv, but guess not~. Okay, go on—try them in front of the mirror."
Ye-eun teased with an innocent grin, and I had no choice but to grab the underwear. Yeah, standing around naked was weird anyway. After sharing a bath with girls, showing off lingerie felt like no big deal now. I started slipping them on one by one.
After hooking the bra and slowly pulling on the panties, I stood before the mirror—and my eyes went wide at the unexpected sensation.
"Huh...?"
"How's it feel? Different, right?"
"Yeah..."
It's more comfortable than I thought. That was my first thought. Worlds apart from the tight, stuffy cotton bra Mom had gotten me. The thin, firm fabric cradled my massive breasts gently but securely. Like someone else carrying the heavy load for me—a sense of liberation. The pain pressing on my shoulders didn't vanish like magic, but it eased up a bit.
"This... is actually comfy."
"See? That's why I told you—gotta wear a bra that fits you perfectly."
"Yeah..."
"All thanks to measuring your bust size so carefully earlier. You admit it, right, Seo-jin?"
"Uh, y-yeah..."
"Hehe, then let me adjust the straps for you."
Ye-eun came around behind me and fixed the bra straps. I flinched, half-expecting her to go for my breasts again, but she just straightened them properly and stepped back.
"Cute Seo-jin complete~. Definitely prettier like this. Right?"
"...Yeah. It's pretty."
Just like Ye-eun said, my reflection looked objectively cute and pretty—even to me.

Even with my hair still damp from the shower and my eyes full of unease, the nice lingerie made me look way better. I can look this pretty too, huh. It hit me then, more real than ever: I was a girl.
"Alright, basics done. Time for the little tips now."
"Little tips...?"
"Yeah. Like how to do makeup, or what girls like."
"Wh-why do I need that...?"
"You'll need it all. Come here."
Ye-eun tugged my arm with a grin. My strength was gone anyway, and I was too dazed by my new look to resist. Luckily, she really did drag me to the vanity and started teaching makeup.
"Okay, Seo-jin. Makeup basics start with moisturizing..."
"W-wait...! Nothing complicated, please. Just no-makeup makeup? The simplest way."
"Hmm? That's the hardest part."
"What...?"
"Fine~. Well, your skin's so good, no need for heavy layers. Just the basics."
She dabbed skin essence and lotion onto a cotton pad, gently wiping and applying it to my face. Then, with something called cushion foundation, she patted my cheeks lightly. "Don't rub—pat gently to blend," she explained kindly.
"Eyebrows? No need to draw 'em—just fill in the sparse ends a bit."
"Okay..."
"Finally, lips. Yours are so pretty, tint balm's enough—no need for heavy lipstick."
"Got it."
"Still got some left, so I'll do it all. Just remember what I taught~."
Her soft touch brushed my lips, and the makeup was done. Looking in the mirror, a brighter, more vibrant beauty girl smiled back—way livelier than before.
"Whoa... it's really different."
"Right? Not overdone, just pretty. Like it?"
"Yeah... it's pretty."
As I stared dazedly at my made-up face, Hye-won approached from behind. She glanced me over, nodded, and added,
"Yeah, looks good. But what about those baggy guy clothes?"
"Right. Seo-jin, you're not thinking of putting those drab guy clothes back on, are you?"
"Huh? Then what do I wear? That's all I have."
"Obviously, borrow mine!"
Ye-eun flung open her closet and quickly picked out clothes: a soft white off-shoulder blouse and light blue denim skirt.
"Try these. With your figure, they'll look perfect."
"Uh... huh?"
"Size should be close enough. I'll lend 'em—if you like, keep wearing."
"Ah, uh... okay."
After changing into them semi-forcibly, the two clapped and cheered. The off-shoulder blouse bared my shoulders coolly while dizzyingly accentuating my 70D bust, and the short denim skirt showed off my smooth legs. Even I thought it was too girly—my face flushed hot.
Ye-eun watched my reaction with satisfaction, then grabbed my hand.
"Outfit's perfect now, so time for what girls love most."
"What girls love most? What's that?"
"Follow and see."
Led by Ye-eun's hand, we ended up at a popular dessert cafe downtown. After ordering a bunch, the table filled with treats: fresh strawberry croffles wafting sweet aroma, colorful macarons, and cool, sweet drinks. Baffled by combos I'd never tried as a guy, but weirdly tempted.
"Dig in. Girls gotta eat something sweet and tasty when stressed or needing a pick-me-up."
"R-really...?"
"Yep! Trust me~."
Ye-eun cut a big piece of croffel and brought it to my mouth. I took a bite—and the melting sweetness made me smile unwittingly.
"Good, right?"
"Yeah. Really good."
As I chewed and answered, Hye-won snorted from across the table, slurping her iced Americano.
"Jeez, unbelievable. Seo-jin, don't fall for it. She's just using you as an excuse to pig out on sweets."
"Oh, Hye-won. Way to kill the vibe? Seo-jin's loving it."
Watching them bicker, I burst out laughing too. Made up like a girl, dressed like one, munching girly snacks and chatting—it felt like I was a normal girl. Strangely nice.
Living as a girl... might not be so bad.
The thought startled me, but the vibe was that good.
Sunset came before we knew it, and we stood to head home.
"See ya."
"Already, Seo-jin?"
"Yeah, gotta eat dinner... Catch you later."
"Okay~. See you at cram school next week~."
Hye-won waved casually, and Ye-eun smiled as she saw me off. I'd worried they'd cling, but they let me go easy. Sighing in relief, I turned to head home—
"Oh, Seo-jin. Don't forget what you learned today~. Got it?"
"Eek?!"
"No slacking on practice. I'll check later~."
Check? It sounded like doing that again. Speechless, I just bolted without a word.
My face burned.
"N-no way...! Just watch me...!"
I shook my head fiercely, steeling myself. No more days like today.
But heading home, I didn't realize—from the moment I heard those words, my pussy had secretly started getting wet.
