Sanae was surprised to come across what she had just found in Gensokyo, left in an unused junk pile by some kappa she had finished conducting business with. It looked like an old parachute rig, the type that appeared to be used by military paratroopers in the outside world from the past. She couldn't quite place what decade or country the gear was from, but it in good shape seemed familiar enough to her. She recognized the main pack on the front, the reserve on the back, and the harness assembly that kept everything together and on its wearer.
Now she found herself curious. She'd seen a lot of movies and maybe the occasional airshow display, but she'd never really thought about parachuting herself before. Here, in Gensokyo, she and everyone else could fly with little restriction. Since she was by herself and had some free time with her outing concluded, she thought she would experiment for a bit…
First, she'd make sure that it worked. She held the pack out in front of her, and pulled on the large, conspicuous handle on the front of the pack. Nothing quite happened; she assumed that it probably was meant to open while she was moving. She reached into the pack and pulled the folded chute out gently, holding it out to the air while running backwards, handling it like a kite. It unfolded and trailed in front of her for a bit, but as soon as she stopped running, it flopped to the ground.
Sanae then got an idea. She picked up the chute again and started trying to run with it again, although this time she invoked a small amount of the wind magic she innately possessed. The parachute began to inflate, becoming the familiar dome of green silk as it flapped and fluttered in the wind… Sanae had to keep running to not get dragged back in the opposite direction. She looked at the canopy as she continued to move along… it looked to be in good condition in spite of its age, with no unusual holes or damage. Once she was satisfied with this test run, she pulled on the lines, trying to collapse the canopy back down and bring it to the ground.
It was then that Sanae decided to start putting the rig on. She wasn't going to bother with the thigh straps; getting them around her with her skirt on was too much trouble, and she wasn't going to go to the lengths of taking it off out here… she put the upper part of the assembly on around her shoulders and chest, the main pack settling in under her ample bust and pushing it up, even more so when she tightened the other straps. Once she felt comfortably settled in, she picked up the parachute lines off the ground, running along to let the canopy catch the air again…
Once the canopy was inflated, she started to use her wind magic to try and guide it above her… the wind also blew under her skirt, causing her to blush slightly… if anybody were watching her, they would have seen the blue-and-white striped panties that were a trendy fashion for girls in the outside world… Sanae started to float in the air, strapped in the parachute as she began to rise gently, starting to ascend above the treetops…
Eventually, Sanae stopped her wind magic, letting gravity take over as she started to float back to the ground. Her breasts bounced slightly as her momentum shifted in the air, and the wind blew against her legs, making her skirt gently billow and possibly exposing her panties to any lucky onlookers. She looked around, enjoying the ride as she gripped the risers. She didn't really know how to steer the parachute, but she looked like she was headed for a soft landing in the clearing she had taken off from.
After some time, Sanae touched down back to the ground, landing on her feet. She took a moment to absorb the shock of the landing travelling through her body. The girl laughed and smiled, putting her arms out as the canopy started to deflate. The parachute settled to the ground, landing on top of Sanae and covering her feminine figure like a statue. She had enjoyed the thrill and wanted to jump again when her free time would let her...
