Bumping this for an unrelated opinion. I'm a big voyeur myself, and I have my wife in a cabin right now that is obviously set up for spying. Cracked blinds, windowed bedroom doors to secluded accessible decks with no working lights, and a hot tub that is clearly seen from the edge of the owner's privacy fence.
Do I owe it to a fellow voyeur to let him have his fill of watching my unaware wife?
i think you should.
I think it's your duty.
If he watched, I made sure he got a hell of a show. Fucking in the hot tub, positioned her for a good view on the bed where he could watch from the dark deck, and made sure her blinds were cracked during her shower.
I hope he watched and enjoyed.
