"...wow..." Looking down, Rainbow Dash rubbed the back of her neck nervously. "This is...I mean wow! I...I can't wait." 'Ah, hell with it. She already knows.' "I get to spend the whole weekend in a diaper! This is even better than Twilight's tickets."

She jumped over to her friend, pulling her into a slightly too strong hug. Releasing Rarity, Dash stepped back, looking at the diaper. "So, uh, we're waiting 'till tomorrow? When can I come? I- I don't mind getting up early."

Rarity looked at her friend bashfully. "I don't see why we couldn't begin immediately," she said. "Everything is set up perfectly," she continued, glancing around the room at all of the effort put into making her dressmaking room look more like a nursery, but only in some aspects. It was still her dressmaking room.

"Awesome!" Rainbow Dash trotted over the diapered mannequin and tried to remove the diaper, noticing the cutie mark on it immediately. She fought another flush of heat in her cheeks. She had never had any like that, and she had always wanted them. It looked thick too, much thicker than her dwindling supply.

She glanced at Rarity, embarrassed as she realised something. "Uh, Rares...I've only worn disposable ones before. How do I put this on?" As incredibly awesome as this was, Dash knew, it would be weird to ask for Rarity's help. For once she found herself unable to go through with something, wishing she hadn't thought about it. Things were so much easier to do when she just did it without bothering to think.

"Would you like me to put them on for you?" Rarity asked before realizing what she had even asked. A blush grew across her face. "I-I mean, show you how? The buttons . . . on the side, heheh . . ." she trailed, trying to make it not seem awkward. Clearing her throat, she continued, "There are these cute little buttons on each tab that snap into place. Just pull," she instructed.

Her mouth hanging open for a second, Dash wished she had said 'yes' in time before getting a hold of herself. 'No need to weird your friend out.' She reminded herself.

"T-Thanks." Just as she pulled the diaper off she remembered the "reliability" thing. "You wanted to test this for reliability or whatever, right? Uh, I don't wanna get a rash or something so do you have any...any powder?" Rainbow could have sworn her face had been lit on fire by this point.

Rarity was already a step ahead of her. "But of course! I couldn't subject you to such a risky treatment without proper care, could I?" she asked hypothetically, using her magic to levitate out some powder from a shelf underneath the changing table. "Oh, but I don't have any mats or anywhere you can get into it. You may use my bathroom if you wish," Rarity told her, leaning up against the changing table. Of course she didn't want to push her friend into anything so quickly!

"Actually..." Rainbow Dash found her eyes held fast by the changing table. She approached it cautiously. "I mean, since its here it would be waste....and, heh, you know how I hate walking further than I have to." She added as an extra excuse, hoping that citing her laziness (when the Wonderbolts weren't concerned at least) would help. Her wings got her onto it easily enough.

On a changing table, a thick cloth diaper ready to be worn....this was the best birthday present ever!

Rarity somehow knew Rainbow would go for as much realism as possible. "Alright Rainbow," she called as she walked toward the door, "I'll give you some privacy for the time being. I need to prepare dinner downstairs anyway so, would you like anything?" she asked the eager pegasus.

(Thought for this scene might do a bigger post. Wasn't sure if you wanted it kept it in that room for now, but feel free to have Rarity get back before she leaves or gets far.)

The pegasus didn't give it too much thought, too entranced with her diaper. "Nah, I'm good. Maybe a snack and drink or something, I ate at the party but its been a while."

Turning her attention back to the diaper with waiting to see if Rarity had closed the door yet, Rainbow Dash finally lifted her rear and pulled the diaper under herself. Powder awkwardly held between hooves while trying to lie back as best she could she gave it a very firm shake. Maybe a little too firm, the mare mused as she coughed.

Breathing in the smell was exciting nonetheless. Dropping her butt onto the diaper, Dash spent a few seconds wriggling to get her tail through the slit provided as she slid the diaper on. It was already feeling way, way more comfortable than her disposables, and when she finally got the taps snapped into place a sigh of pleasure burst from her.

It was soft against her coat, like she really did have a cloud around her. Rainbow Dash giggled, happy to let the sound out right now.

Getting down from the table proved awkward in the most delightful way. The thickness of the diaper spread her back legs and when she walked she was forced to keep them out wide and waddle. Another giggle preceded a reminder that she had brought her plushie.

'I did want Rarity to fix it...she won't mind....' She thought, pulling it from the saddlebag she had left by the door. Setting it on her back, Rainbow Dash tried not to grin as she waddled out to find Rarity and thank her.

'Best. Present. EVER!'

(Just do what you think the scene calls for. This was actually quite adorable! o3o )

Rarity was in her kitchen putting together something small for the both of them, as Pinkie's party had been rather filling like always. Of course, with Rarity's finesse, the meal she was creating took on the form of an exquisite culinary creation. She levitated some potatoes, garlic, rosemary, and a few other ingredients around herself as she searched through her organized cabinets for the right cutlery. Once satisfied with her ingredient selection, she set everything down and began the first step.

Before long, she could hear hoofsteps coming down her stairs. Rainbow must have finished up in the dress room, and was now coming down. Setting down what she was doing, she trotted over toward the stairs to meet her.
