Given two arithmetic sequences $\{a_n\}$ and $\{b_n\}$ with their respective sum of the first $n$ terms denoted as $S_n$ and $T_n$, it holds that for any positive integer $n$, the ratio $\frac {S_{n}}{T_{n}}$ is equal to $\frac {2n-3}{4n-3}$. Find the value of $\frac {a_{2}}{b_{3}+b_{13}}+ \frac {a_{14}}{b_{5}+b_{11}}$.
