Subject: How to have a unique primary key on two tables

Hi everybody,
I need to have a primary key which has to be unique on two tables.
E.g.:
CREATE TABLE first
(
id serial NOT NULL,
testo text,
)
CREATE TABLE second
(
id serial NOT NULL,
testo text,
)
When I insert some text on "first", I would like first.id = second.id
+ 1, and vice versa.
A sort of primary key in common for both tables.
Any hints?
Thank you very much
