Hidden camera discovers infidelity

His day was going normally, he had finished the day's work, he was getting ready to receive his wife, but before that he had the idea of checking the security camera. He had never found anything strange, but it didn't hurt. The quick camera proved him right as he found nothing strange or that could cause concern. Everything changed when he arrived last Thursday. Then he witnessed his wife letting in a man he didn't know at all, but who was offering her some product. A few moments later the two of them were naked and having sex on the couch.
