Adultery could mean life in prison???

This is a very interesting story in the Detroit Free Press.
Apparently anyone having sex w/ penetration while committing a felony is guilty of Criminal Sexual Misconduct of the 1st degree which in the state of Michigan can be punishable by life in prison. And according to an older law on the books, adultery is technically a felony. So don’t get caught having an affair as it can now be punishable by life in jail.
I think this is what happens when you try to convict someone of a crime and the judges read more into the law then they should. And what if the Attorney General had affair, does that mean that now he should face life in prison?
Hey if this law means less people have affairs and maybe work on their marriages instead I’m all for it. But somehow I doubt that.
