I've used voyeurism as a theme in many of my stories, although I have never actually submitted a story in the voyeurism category.
I have used a voyeuristic theme for erotic purposes in my lesbian story 'The PTA Queen Bee & the Teen Rebel', where an attractive married woman in her 40s (the titular PTA Queen Bee character) enjoys up-skirting women much younger than her such as her office assistant.
In my 'Spoiled Princess Hates Camping' series I use voyeurism for humor, where a bumbling 18-year-old young man is obsessed with perving on his pretty cousin (the spoiled princess from the title), other female cousins and aunts, and his twin sister's friends.
