>>4007784It's from the Singularity 2018 event art / cosplay photo book that has a lot of Kurisu and Suzuha cosplay in some sexy poses. I have no idea where to get proper scans of it (if they exist) or where to get a physical copy. I know there are illustrations throughout it but I've only seen that Kurisu and this Suzuha by Ikeda Yasuhiro and one with both of them by Huke. There may or may not be more in there.
