Let $R$ be a commutative ring with identity and $M$ be an $R$-module. In this paper, we introduce and investigate the second submodule intersection graph $SSI(M)$ of $M$ with vertices are non-zero proper submodules of $M$ and two distinct vertices $N$ and $K$ are adjacent if and only if $N \cap K$ is a second submodule of $M$. Also, we introduce and consider the prime submodule sum graph $PSS(M)$ of $M$ with vertices are non-zero proper submodules of $M$ and two distinct vertices $N$ and $K$ are adjacent if and only if $N + K$ is a prime submodule of $M$.
