1- show you masturbating into you panties then pissing (and maybe shitting if you're into that) into the panties then you sniffing/licking/sucking on the panties, hopefully you can take pictures of just your mouth without showing your face.
2 - licking your shit (or from whatever person/animal you can find)
3 - pictures of you pissing through your panties in a public restroom then going out in public with them still on
4 - go to the park with a blanket, and cover yourself up totally, take all you clothes off under the blanket and take pictures, continue taking pictures while masturbating
5 - wear the same pair on panties for a week, then on the last day, put on a good pair of shoes (high heels work best i believe), go for a long walk and get all sweaty, when finished, blindfold yourself, take your panties off, gag yourself with them, then take a shoe and tape it to your head over your mouth and nose (hopefully this will sufficiently cover your face)
