Voyeurism is a big kink in this fandom because of the CCTV being used in the Hub, I think... it occurs to people as something they can use (and we used it as a porn battle prompt). But I don't think Tosh needs to prove she's a genius by being able to pull up porn vids. And Jack and Ianto would be aware that cameras exist, and I highly doubt any are in Jack's hole (LOL). I don't know... you'd have to set this up for me as a kink or plot point in the story and not a throwaway.

Even though we are all voyeurs by reading about them doing it. LOLLLLLZ. :)
