Maybe five or six years ago my wife and I attended a Halloween costume party hosted by a friend of friend. We wore matching his and hers Pirate costumes. The outfits were not the sexy versions but Sara, my wife, looked sexy as hell in hers!
It was a small gathering, maybe 15 or so people, and most of the guests arrived at the same time. There was a nun, a guy in a dress, vampires, Spider-man, Frankenstein, Elvira, and a few others. The evening started off a bit slow, but as the drinks flowed and the music played everyone relaxed and had a good time.
A chunk of the guests all worked together, or had worked in the same place, and as the evening went on a couple smaller groups broke away form the shop talk. I had wandered off for a drink and wound up flirting with the hostess for a while, but eventually went looking for my wife.
I found her at the top of the stair case. She was waiting to use the bathroom and carrying on a conversation with whoever was inside. As I started up the stairs I saw the bathroom door open and Spider-man, or rather a tall guy dressed in full Spider-man body suite, emerge.
