It was just as he was thinking about Camille when he felt something sticky and wet under his hand. He turned on the light and looked at it. He couldn't believe his eyes, and prayed that it wasn't true. For it was quite clearly semen that he had found on the sheets, and Tom knew that he and his wife had not had sex for several years now.
Of course, he had a 15 year old son, so he thought it might be that his son was having sex. But then, Tom looked at the dirty clothes by the bed and saw that his wife's underwear had cum in it. It was then that he knew. She had started to hide her clean underwear even since she discovered Cullen stealing it to wear for himself. Tom started to get angry then, for he knew what this meant: his wife was having an affair.
