A few houses down from Jon's, a man was about to have sex with his wife. They had only been married for a year and they had been trying for some children.
Before David (the husband) put his penis into Marilyn (his wife), it tingled. He looked down at it, but there was nothing wrong, so he entered his wife.
What David didn't know was that Jon was now David's penis and he was feeling everything that David's penis felt as he had sex with his wife.
