Someone could always write that their character listened at the door, stood outside the tent, or peeked through the bushes/cornstalks.  Having it in a different thread is just so it doesn't drown a main thread with 2 people posting back and forth.<br/><br/>If you want your character to spy on a couple, or maybe inadvertently walk in on them, then communicate with the other players and make the scene happen.  The smut thread might be a separate thread but it still occurs within the confines of the larger scene - unless of course the couple are truly alone.
