I managed to find these links, try to search for their cgs or , if you have time, u can download them and see if they are the ones you are looking for. Also, 1 tip, u can search google for the image.
When i search google i usually try to get the name they give me like a grammar correction and then just add ehentai next to it and see if any gallery contains it, if it doesnt i just add getchu instead or dmm and see what games they give me.
P.S. sorry if posting links is not allowed, please notify me as i will fix the mistake as soon as i can.

I don't know if it's late but this CG is from this game: みだらなマンション
