Over the course of the night, the two festive mummies, trapped in their strapped stockings, finally grew tired. Their struggles leading to fatigue and exhaustion. After a few good hours of sleep, the two of them were awakened by the sound of rustling. The rustling of the wrapping paper being pulled away from their heads. As they opened their eyes, they were blinded by the harsh light of the room they were in, but that light began to recede as something pink got in its way. That led to a revelation. Only one thing is that tall and that pink.
 
Standing in front of them was none other than Pinkie Pie, clad in one of their outfits, a grin planted on her face as she walked over and hugged the bound lovers that were left leaning against the wall . Thus, the next revelation hit. The mare that did all of this, binding them, wrapping them, and stuffing them into a hanging stocking.. Was her.
 
The two wrapped mares gave a sigh into their gags as they rolled their eyes. Of course it would be the one mare who knew what their shared kink was, and considering that before they left for their cottage, the Earth Pony warned them that she had “something special” planned for them this Hearth’s Warming Day. She just didn’t tell them what. Now that the mare of laughter had them where she wanted them though, who was she going to have fun with first, as she pointed her finger between the magical mummies..
 
Eenie..  
Meenie..  
Minie..  
Twilight!
 
She skipped over to the wall and quickly scooped Twilight up in her arms, pulling her close so that the princess’ wrapped chest pushes slightly against her’s. Of course, this did not go well with Rarity, who became quite furious. Nopony had the right to bind and wrap her marefiend up and toy with her. Not unless it was her. And as soon as she got out, Pinkie was so going to get it.

Gift-wrapping a princess and giving her away is high treason in its sexiest form.

A very merry christmas. Also, pinkie is stronk.
