Wonderbolts headquarters, A random cloud, Cloudsdale, 8 pm.
 
An animated conversation was going on between Soarin and the potential wonderbolt Rainbow Dash during sunset.  
The wonderbolt stopped the conversation to say that it was getting dark, and they should get home.  
But, getting pity on the pouty mare, who didn’t want to stop talking with her friend, Soarin decided he’d invite her home, and the conversation could continue there.  
After offering her a drink, Soarin decided to pour her a glass of a special drink.  
Going through the bottles he kept in his cabinets, he found something she could enjoy.  
“Sidra asturiana. 7% etanol.”  
It was a rare drink, uncommon in Equestria, imported from the human world.  
“I recall this was a special kind of cider.”  
Humans had a different way of making cider, and human cider was known to taste harder and burn through the digestive system. Some ponies thought it was poison, but some others loved it and claimed it tasted good once you get used to it.  
Dipping her lips in the strange beverage, Rainbow Dash felt warmth around her mouth.  
Trying it again, she sipped gently, felling the temperature in her tongue and throat increase for some seconds.  
Not wanted to be rude to the respectable wonderbolt, who was kind enough to invite her, she continued to drink slowly as the conversation continued.
 
Soarin’s house, another random cloud, Cloudsdale, 9:00 pm.
 
The empty glass was lying on the table. After a quarter of a litre of the drink, the female pegasus didn’t feel anything burning now. It didn’t taste that bad.  
She did feel a little tipsy, as she spoke to Soarin about how much of a good flyer he was, quote, “almost as good as me”.  
On the other hand, while Rainbow’s speech was as animated as one hour ago, Soarin was starting to feel uncomfortable with her manners.  
She was getting closer and closer, didn’t hesitate sitting just next to him and poking his chest and belly as she mentioned him, and seemed to sound honeyed.  
“Uh… it’s time for dinner!”  
Soarin flew to the kitchen to get some food, and rid of some of the awkwardness.  
Back into the living room with some hay pizza slices heated up, he found her, pouring herself another glass.  
After the pizza was placed on the table, she happily ate a couple of slices, stopping every once and then to drink a little more.  
“So… we were talking about how awesome I… about how awesome you… th’hay, you are so awesome… I always wanted to…”  
Soarin gulped.  
“…Sleep… aren’t you tired? It’s sleeptime…”
 
Soarin’s bedroom, the same fucking random cloud, that floating city which isn’t called Columbia, 9:30 pm.
 
Clothes spreaded on the ground, two pegasi on the bed.  
One of them doing something questionable.  
The other one wearing something more questionable.  
Frills, ribbons… a diaper?  
“Awwww… just look at you!”  
“…”  
“You are the cutest thing I’ve ever seen!”  
“…no!”  
“I just want to snuggle a fiwwy all night long…”  
“…”  
“Aww… grumpy Soary…”  
“Rainb…”  
“Who’d have swore that you had such a cute dress in your closet?”  
“One of my friends wanted to throw it to the trash and I borrowed it to make rags for cleaning.”  
“Suuuuuure, and what about the diapers?”  
“…”  
“The harder you blush, the cuter you are.”  
“No! Ain’t cute!”  
Rainbow Dash giggled.
