read two posts before logging in

Hi,
Is it possible to use this after a certain two pages have been viewed?
For example, I have several articles that are listed on a page called, Current Features.
My readers can pick and choose stories from this page that they are most interested in.
I’d like to offer two of these for full reading – and then, when they go to access a third, they are asked to login / register.

Is this possible please?
With thanks
George
