Fear not, I have done moderate amounts of research and found the sauce for the top image. Artist is alp.
I have no idea what the source is for the bottom image, but it looks like it’s by the same artist.
E: JK I found it, https://alp315.fanbox.cc/, the bottom part seems to be paid content.
E2: After more research, I have found both images. https://e-hentai.org/g/2004467/be9e42f3d6/?p=2
