There exists a photo (possibly even more) of a readhead/blondish girl getting fucked in the butt by a guy. The girl is very skinny with lots of freckles on face and shoulders. The pic is probably taken from behind. Setting is a sleeping room in a therapy facility. The pic was taken by another girl with a smartphone.
If anyone goes so far as to analyze EXIF data: The pic is taken in northern Germany circa last year.
Any help would be greatly appreciated. Please post everything that might fit the description.
