as she is okk with being no face exposed.
it would be fun to make her have a physical photo of her in a male washroom, which she leave after she cum in that washroom stall.
(remember the dress must be the same as her clothes from the pic. )
this way those males who use that stall. can assume that she left the pic in there on purpose.
ofc she can leave from that place after a few people goes in the washroom.
this is just to humiliate not to expose her with face.
a whore with that figure sure to keep a simple image in almost every male.
