A very warm hearth's warming eve

"Happy Hearth's warming mom!" Twilight hugged her mother, then stretched her back and arms, taking a deep breath.
"Happy Hearth's warming sweetie. It's so nice to see you again!" Twilight Velvet took her daughter's hand and led her over to the freshly decorated upstairs area.
"Sorry for being so late. Thank Celestia I gave Shining Armor a spare key for cases like this. The meeting with Celestia and Luna took far longer than I could've expected... Their new plans for equestria are far more ambitious than I could've ever even imagined!" Twilight's face blushed slightly. Her composure quickly returned to normal as Shining Armor walked into the room.
"Sup sis? Nice to see that the princesses finally let you go." Shining Armor laughed as he handed Twilight a warm mug of strong eggnog.

"I hate to do this to you two, especially since pa is no longer here, but Flurry Heart's probably screaming at Cadance already for her presents at home..." Shining Armor grabbed a large wrapped box and placed it next to Twilight.
"I want to at least be here when we open the presents, like we used to." Shining Armor smiled as the three gathered around.

"Thanks Shining." Twilight smiled and took a sip from her eggnog. Her mind was still racing due to the meeting with the Princess sisters. The legal changes the two were planning to implement were still fresh in her mind: Complete nullification of public indecency laws, full legalization and royal advocation of incest... And most amusingly: mandatory government dresscode, consisting entirely of skintight latex...

Twilight couldn't help but interally giggle at what the sisters and Cadance had shown her. It must've been just an ellaborate prank...
"Here ya go sis! This one's from Celestia and Luna. First one of the three they sent here- Oh hang on, there's a letter..." Shining armor opened the letter, stamped with the royal insignia and started reading:
"Happy Hearth's warming Twilight, my most beloved student. I hope these gifts make the transition into our new world more enjoyable for you, your mother and your big brother~"
Twilight's heartbeat tripled. As she grabbed the top of the box, her hands began to tremble. This couldn't possibly mean what she was imagining...

"Those two sure love being cryptic don't they sweetie? Come on and open it! I'm actually curious now."
Twilight Velvet teasingly bumped Twilight's shoulder as Twilight took off the package's cover...
"Oh- Ohmygod..." Twilight looked inside the giftbox and then placed her hands inside it...
"WHAT! WHAT IS IT?" Both Shining Armor and Twilight Velvet yelled in unison upon hearing Twilight's completely baffled reaction.
Twilight face twitched as she slowly lifted the purple latex bodysuit from the box and into the view of his mother and big brother...

How nice of the princesses to send separate gifts to all three of them.
