Not only same underwear but same bedspread. You nailed the title. Outstanding!If you look at the top right corner above the vid there is a source button next to the word asian, the video is in there.
I'm about 90% sure it's from MMKZ-002. I didn't see the clip in the vid but she's wearing the same underwear
All of these look like they came from Reddit, if you click the "post source" underneath the title it takes you to where it came from. Couldn't find a source although it kinda looks like Kurea again
