Best supplier of belly movement videos on the internet.
Belly Movement Google Drive: https://drive.google.com/drive/folders/1-TLre6pX3FY_JVCmmQZaKG9oCvy2W5-5 (UPDATED: ADDED 30 new videos "Moving-J1 to Moving-J30" on 11th March 2024)
I update it kinda infrequently but it's usually around once a month or two. All the newer videos are titled "Moving-X25" for example. Look for those. Just going up the alphabet when it comes to naming them. Might get around to sorting out all the videos with random names into an neater, more organised category like the newer videos I'm uploading there.
