For her 40th birthday, he gave her a one-time very special gift. He told her he had invited a friend over. He didn't tell her who, and blind-folder her so she'd never know, and always be guessing, trying to match the face and every seemingly knowing smile or wink with the memory of the anonymous cock. It was a wonderful guessing game, seeing every male friend as a possible lover, knowing that one of them had shot his load into her hungry mouth. Not knowing was so much better than knowing. It was truly a gift that kept on giving.
