First one is "Oppai Fukkireta": https://ecchi.iwara.tv/videos/yo6qwcjyvkt0xjqeb. all links i found take to the motion creator's Fantia page, but the motion itself is not listed on the page.

Second is "Kitty Cat": https://www.iwara.tv/videos/qapzju9axhrrbvj9. The only link i found for this one is broken.
