The way the animated scenes are setup, each part of the picture is separate to allow for moving parts, etc. The particular file is the uncensored cock used during deepthroat, independent of costume. The path of the file is inside of a packed gpx file...which took a lot of hoops before I managed to get it to work (with lots of appreciated help from
Reimu_Hakurei). However, after looking into the file, I noticed that the positioning file for the png has a space at the end (like in your pic), while the png did not. Not sure why it works for me so readily while not on your pc, but I've created a non-space positioning file and a spaced png to cover either possibility and repackaged it in the link below. Just drop in the main game folder and overwrite. Let me know if it works for you.
