My mind is full of naughty thoughts

I wish I could sleep but I can’t stop thinking of another man laying beside my wife, they are facing each other on the bed as they cuddle and kiss. I am laying by myself as close to the edge as I can listening to them. I am so turned on knowing that she will soon be his. I feel a little creepy being there and decide to go down to the livingroom to give them space…….there are so many ways I could see the night ending! What is your favourite evening with a woman?
