After being moved about for Celestia knows how long, the box containing the two festively-dressed captives stopped its shaking and bumping and.. Moving. The box had completely stopped. the passengers though would not notice this right away, sleep finding them during their transport. What woke them from their slumber was something hitting the box, the creaks coming from the nails holding the box closed as the top was propped up and pulled away. The two sleepy mares attempted to look at their surroundings, but once more, it was dark. Once the box was tipped up, things began to show up a little more clearly.
 
They had been taken to a large room. A barn, or what appeared to be a barn. They could only make out the outlines of a few things in what little light entered the building. This didn’t help them either when it came to identifying their captor, who stepped forward and into their view. Once more, they couldn’t see a face, but their silhouette identified them as a mare. They could see what looked like a smile as she grabbed Rarity, pulling her out of the box. An action that was more than enough to revive the struggles from Twilight Sparkle.
 
The captor cut the ropes away from the ivory unicorn, save for the ones binding her arms and legs together. Then, she began the process of cutting the clothing away. Carefully slicing and pulling away the dress, gloves and shoes. Then, the captor went a step further, slicing off her bra and panties, leaving her completely naked. The kidnapper then picked up the now beet-red Rarity, her struggles renewed in the arms of her enemy, but the mare holding her was just too strong. She was then placed down upon a material. Something that crinkled under her. Before she could identify what it was, the hidden pony began to roll her. As she turned though, the material followed along, and before she knew it, she was wrapped tightly in some sort of paper. Completely mummified from her muzzle down, her screams now more muffled than before.
 
The next thing she felt was something go around her neck, and finally, something was hooked to the back of her wrappings. Before she could give of any further struggles, she was hoisted into the air, the cord that held her tied off on a hook, keeping her suspended. It was then when Twilight could see what was done. Her marefriend was wrapped up in green and red striped wrapping paper. Thick wrapping paper. A fluffy white collar was placed around her neck, and she was trussed up, making her look just like a Hearth’s Warming gift for somepony.
 
Once the captor took care of some last minute adjustments, she turned around to face the princess still bound inside the box. Already seeing what happened to her special somepony, she knew what was in store for her.

They look so comfy!
