Very Hot, I can only recall one time I sat in the same room and just watched my wife get fucked. But I had many experiences secretly watching her get fucked by guys who had no idea I was there. Quite a few were at our house, my favorite was when she seduced 3 guys who were installing carpet and she asked if they'd lay her? And boy did they. But my favorites were in hotels when she ordered a pizza or something like that and end up seducing the delivery guy/girl and I'd be hiding & watching. It normally was just a blowjob but on occasion it went further.
