To address the issues of superconducting and charge properties in high-Tc cuprates, we perform a quantum Monte Carlo study of an extended three-band Emery model, which explicitly includes attractive interaction VOO between oxygen orbitals. In the physically relevant parameter range, we find that VOO acts to strongly enhance the long-range part of d-wave pairing correlation, with a clear tendency to form long-range superconducting order in the thermodynamic limit. Simultaneously, increasing |VOO| renders a rapid increase of the nematic charge structure factor at most of wavevectors, especially near q=(0,0), indicating a dramatic enhancement of nematicity and charge density waves. Our findings suggest that the attraction between oxygen orbitals in high-Tc cuprates is a common thread linking their superconducting and charge properties.
