It look like supremekitten have made some nice progress on the Idle cub spanking flash animation. Not it is in color and the cats body move back and forward now. That look really nice and make it little cute to.
You find the new version here on Inkbunny: https://inkbunny.net/submissionview.php?id=571238 and you need to have an account on Inkbunny to access this flash spanking. But it costs nothing to create one.
