Dress Shopping For MiyaMiya

"Come on, Miyabi, we've been standing around in here all day." you said as you started to lean against a nearby clothes rack. You'd been dragged, physically dragged, out of your home by Miyabi earlier this morning and taken to this huge department store that you'd never been inside of before. You still haven't figured out why exactly Miyabi dragged you here, or why she needed you for shopping for new clothes.

"No, Anon! We have to find it! There must be something here!" she shouted at you from inside the changing room she was inside, a flurry of sounds and movement coming from within. You still had no idea what she was looking for, but based on the selection of clothes that she'd made you carry to the dressing room, she was looking for a dress of some kind. Of course, you had no idea what else she could have grabbed to try on, since she threw enough clothes into your arms to create a veritable pillar, though it didn't compare to the two towers of clothing she had managed to carry to the dressing room on her own.

"What, exactly, are we looking for, Miyabi?"
"A dress! No, THE dress! The one that shall help me declare my femininity to the world! With it, I shall never be mistaken for a man again!" she shouted at you, loud enough that the door to the room she was in started shaking, making you thankful that there didn't seem to be anyone else in this section of the store. There was a soft click from the door, and Miyabi was standing in the frame, wearing a long, white dress with short poofy sleeves and frills on the cuffs along the cuffs on the arms and at the bottom of the dress. She looked positively stunning, were it not for her stern expression piercing through your body.
"Well!? How do I look?" she asked as she gave a small spin. She looked beautiful, though the dress did clash with her hairstyle. Not that you cared, since you didn't care whether she was masculine or not, but the topic was a sore issue for her.
"You know that I think you look beautiful, Miyabi. Dress or not." She blushed at your comment, though it didn't seem like she was satisfied, since she glared at you, groaned, then turned around and walked back into the changing room, grabbing a new dress from the pile and slamming the door.
"You're not helping, Anon! I need to find it! Then I'll never be mistaken for a man again!" she screamed as you heard her frantically undressing through the thin walls of the dividers. "Uggh, Anon please come in here and help me with this!" Testing the door, and finding it unlocked, you set down your pillar and opened the door wide enough to peek in...

...to be greeted with Miyabi striking an exaggerated pose, covering her breasts and crotch while letting out a piercing, "KYAAAAAAAAAAAAAAAAAAAAAAaaaaaaaaa..." She trailed off when she noticed your expression. While you could feel the blush on your face, you were more confused than anything else. It seemed more like a reaction that a naked person would make, not someone in their underwear, and even then it was more over-the-top than believable.
"What the hell are you doing?" you asked. Miyabi started blushing and fidgeting around, embarrassed by her own poor acting, as she started to stammer out an explanation.
"I-I saw in a m-manga that when a woman is walked-in on while she's changing, she should react like that..." she said, her head drooping as her blush started to grow from ear-to-ear. You sighed, walking into the changing room with her and shutting the door behind you.
"Miyabi, for the life of me, I cannot understand why you feel that you need to be so feminine," you said, bringing your hands up to her shoulders, her eyes meeting yours as she started to look up. "You know that I love you for who you are, masculinity be damned." You saw tears starting to well up in them as you brushed the back of one of your hands across her face. "And besides..." you said as you snuck your other hand down to her backside. You gave it a little squeeze, causing her to let out an audible "Eep!" as her blush engulfed the entirety of her head, practically radiating heat towards you. "...THAT'S how a feminine lady would respond to being walked-in on," you said as you gave her a wink and a mischievous smile, followed by a peck to her lips. All she could respond with was dumb-struck look, a blush bright enough you could probably use it to illuminate something, and her forcing you out of the dressing room.
"H-honestly! Now's not the time for that, Anon!" she said, poking her head out from the dressing room. You just laughed in response, and gave her a big smile. You went back to leaning against the clothing rack as you heard Miyabi start changing again, though the sounds of ruffling fabric were significantly slower than before. You started to daydream of that image of Miyabi's face, bright-red and luminescent, when you heard her calling your name.
"What is is, Miya?"
"I want to have your opinion on this dress, Anon," she said, opening up the door. This time, you were the one with a bright-red face, since Miyabi stood in the door-frame, naked as the day she was born, sans the calf-high socks she was wearing. "Well? What's your opinion on my 'birthday dress', Anon?" You could only sputter and stammer out a few words as Miyabi peeked her head out from the dressing room to confirm that there was no-one else around. Then she strode up to you, took your head in her hands, and brought it to in-between her breasts, letting you feel the warmth and softness of her skin. It felt like an eternity before she brought your head out from them, your brain practically boiling inside your skull. She quickly scampered back into the dressing room and took a hold of the door, giving you a good view of her bottom while doing so, before she turned back around to face you. She gave you a mischievous smile of her own, saying, "At least I have some feminine wiles. Right, Anon?" You couldn't respond, your brain trying to comprehend what had happened, so she simply giggled slightly, giving you a wink and a peace-sign with her fingers as she shut the door.

Honestly!
