[b]Most Faithful Toy, Part 2[/b]

[section=Story]
Twilight Sparkle felt massive weight pressing down on her head. Before it became uncomfortable, a fleshy ring moved all the way down to her withers and soft walls of hot, soaking wet tissue surrounded her head and neck. This was Twilight's cue to sit down on her rump and tuck her forelegs. Through the walls surrounding the unicorn, she could identify specific sounds and movements as Princess taking deep breaths in preparation for the second milestone.

What came next was pressure, more pressure, more pressure... and... <flomp!>

With upper body now safely lodged inside Celestia's posterior, Twilight could open her eyes, light up her temporary royal residence and take a look around. Well, there wasn't much to look at, just a mass of wet and squishy flesh, but thinking about what it actually was made the princess' pupil feel a bit uneasy and... fidgety?

Suddenly, Twilight felt her body rising from the ground. [i]What's going on?[/i] She could hear Princess Celestia's heavy breathing and muffled words:

"Huff, huff... we're going on a little walk, Twilight."
