Once the jar is empty, Applejack retrieves a cold bottle of milk to the fridge and holds it in front of Rainbow’s face, suggesting her to drink.

Rainbow Dash looks at the bottle with cheerful crossed eye and accepts it with no question.
“Al-oo-phuf,” Dashie’s mouth engulf the rubber nipple.
Loud smacking noises accompanies the room.

“Would you have ever thought that you would enjoy being a baby after you became captain of the Wonderbolts?”

The totally cool sky blue pony shook her head no.

As Rainbow is drinking, Applejack asks her “So, are you excited to go back to your duties as a Wonderbolt tomorrow?”

Rainbow Dash takes a break from her bottle feeding.
“Oh you bet. I just really need three things to better prepare.
I kinda need my wings unrestrained to get a good stretch in.
Some thinner diapers and … a… butt plug,” the pony first gets excited then embarrassed as she answers her girlfriend’s question.

“Oh, of course I’ll untie your wings. Just remember that as long as you are being punished at home, you have to let me tie them. You don’t need diapers or butt plugs, though. Why do you ask?”

“I can control when I go potty. I can get away with peeing a little cause you know. Butt messing I can hide from the smell or the extra butt bulk,” Rainbow Dash explains. She listens to AJ as she continues her bottle feeding.

“What? Don’t tell me that you became incontinent,” Applejack says in shock, continuing to feed Rainbow the milk.

She nodes while feed from her baba.
