this image was originally only available on Shutterstock for $499 but after some meticulous Google Search(es) I was somehow able to find this gem of an image
Sorry for the no sound video, I was trying to get it with the sound but the quality of the video decreased significantly (worse than a potato) so I felt compelled to go for this option instead, which produced a much high quality of the video.
The redditor that posted her a few months ago deleted their account so I wanted to be able to reupload this masterpiece. Unlike the original one that had about ~1 min of her underarms, I went through the video again and was able to find almost another 57-60 seconds of her flashing her buttery pits, which comes to a grand total of 1 min 57 seconds.
Hope y'all enjoy this :). This is the original video link for those wondering - https://www.youtube.com/watch?v=6GD8Fc29oMg&t=9s
EDIT: apparently gfycat only caps clips to 1 min so here's the full video - https://sendvid.com/co6ss92k
