Spitfire flew.
That was it.
She wasn't flying through any trick or routine. She wasn't flying to any point or place. She wasn't flying for anyone at all. She was just flying.
She let out a pure, joyous laugh as she banked into a lazy loop-de-loop. There was no tight control or careful adjustment, she wasn't trying to impress anypony and nopony was relying on her. All the movements and tricks she did were solely for their own sake, for her own enjoyment, for the pure feeling of flying. This... this was what Spitfire wanted to do more than anything, more than even being a Wonderbolt... though despite everything, she still loved that too, which was why it felt so surreally amazing to be able to do both.
She looked over at her falsely-blue wing and laughed in delight and astonishment. For so long, she'd thought this kind of freedom was impossible for her – when the Captain of the Wonderbolts was flying around, people would always be watching and she'd need to be at her best. But Beach Comber? All anypony would see was a random Pegasus going for a fly. Nothing notable about that at all.
This was the true gift that Fluttershy had given her. The fact that it allowed Fluttershy to see her without worrying about the problems of dating a celebrity was just a bonus, as indeed was the fact that that also allowed Spitfire to see Fluttershy and have all the benefits of talking to and, after a while, dating that miraculous mare. The main purpose, as Fluttershy had told her when she'd come to give it to her, was just to give her somewhere... somepony in which she could just simply... fly.
Looking over to the side, Spitfire saw her marefriend a short distance away, enjoying her own pleasant flight. Spitfire turned in a broad circle, scanning the area to make sure there was no one around to see before she swooped down and in front of Fluttershy, meeting their lips in a gentle kiss.
It would have to end eventually, of course. Sooner or later, Spitfire would have to sadly leave. There would always be another day to get through, another set of tasks to perform, another mountain of stresses waiting to pile onto her.
But she didn't care. Just at that moment, she was happy, she was at peace and she was alone with Fluttershy. And that moment was worth ten forevers.
