Sauce on the images and or a flat image of this pattern?
Looks like panels from Asanagi's doujins.
Not sure if they are all from the same author.

Yeah that looks to be accurate I was hoping to find the collage already made.
They're not all Asanagi, this one is from another famous h-artist called Turtle.Fish.Paint
If you try "ahegao" in google image and scroll down a bit you should see a few collage pics, although I can't spot the exact one that was used for the shirt in the OP.
Ah, there we go. A google image search for "ahegao collage" seems to yield the best results.
Disgusting
