Just had a thought, random chance that when you come to that you have 1 photo and it's of one of the girls in the area inspecting the camera, like when you have a phone or laptop that takes pictures when opened and it's a pets face.
It could be an accidental selfie that's zoomed in and blurry, random scenery, your character face down ass up with cum dripping out of them, a selfie of the predator that ravaged you holding up their hand in a V for victory gesture with the character in the back ground.
Later down the line the level of familiarity could come into play and the more familiar a species is with you the higher the chance they mess with your camera while your sleeping off the best sex you've had in the last hour: a pic of some girls napping next to your character, putting a blanket on you, putting a sign next to your characters ass that reads "open to public".
I'm mostly having fun with the ideas and hold no expectations, just hope I can make someone laugh.
