A married couple were invited to a masked Halloween patry. They were eagerly looking foward to it but at the last minute the wife cried off with an headache. However she didn't want to spoil her husband's fun and insisted that he went on his own. So he set off for the party in full costume.
After lying on her bed for an hour, the wife began to feel better and decided that she was well enough to go to the party after all. When she arrived, the party was in full swing. She qucikly spotted her husband but chose to keep her presence a secret from him, something she was able to do since he had no idea what her costume was. Instead she preferred to observe him, to see how he behaved when he thought she wasn't around. She watched from afar as he flirted, kissed, and danced with other women and then figured it was time to make a move on him herself, still without revealing her identity.
Disguising her voice, she walked next to him and said: "Fancy a breath of fresh air?"
"Sure," he replied. "I know the very place."
And with that, he led her to his car where they had sex on the back seat.
Both returned to the party but shortly before unmasking at midnight, she slipped home alone, removed her costume, and went to bed. Waiting for her husband to come home, she wondered how he would manage to explain his behaviour at the party.
"How was it?" she asked when he finally arrived.
"Oh, you know I never have a good time when you're not there, darling."
"Did you dance?"
"No, not one dance. In fact, when I got there, I met a few mates and went to the den and played poker all evening."
"Oh, yeah?" said the wife.
"But I tell you," he continued. "The guy I loaned my costume to sure had a good time!"
