Given that the sum of the first $n$ terms of the sequence ${a_n}$ is $S_n$, and $S_n = \frac{3}{2}a_n - 1 (n \in \mathbb{N}^*)$.
(I) Find the general term formula of the sequence ${a_n}$;
(II) In the sequence ${b_n}$, $b_1 = 5$, $b_{n+1} = b_n + a_n$, find the general term formula of the sequence ${b_n}$.
