A couple with kids had made a pact that they would always fulfill each other’s physical desires every time they were in the mood. They had also thought of a secret way of communicating with each-other so that the kids would not understand..

For example, every time one was in the mood for sex, they would say to the other: “can you please help me type a letter on the typewriter?”.One day the dad was in the mood, but the mom was working late. She calls home and their son answers the phone. While they were talking, the dad tell the son to ask mom when would she come home because he needed help “typing a letter”. The woman responded she had a lot of work, but to tell him that she would be home as soon as possible.After a hour, the wife called again to say she might be a while longer but she doesn’t know how much exactly, so she told the son to tell his dad that she is trying to come home ASAP, to help him “type the letter”.The dad hears and says: Tell her no need to rush, I couldn’t wait so I just “wrote it by hand”.
