Мой пасынок отсосал у меня, пока я звонил моей жене

I swear I didn't ask him to give me a blow job. I was just lying there naked and texting my wife. We were discussing what she was going to cook for dinner when this insatiable boy suddenly started sucking my cock. And he didn't stop until I came in his sweet throat. What should I tell my wife now? Or should I keep this our little secret?
