limit the number of times a subscriber can login

Is there a plugin that will allow me to limit my subscribers so that they can login only once (only successful logins would work, not login attempts). I want to use wordpress to distribute content, but i want to only allow the content to be viewed once. If the user wants to view again, we would go into the plugin and manually up their limit to two.

An alternative would be something that would change their password after they login once so the login doesn’t work again.

Thanks!
