Installing additional outlet to the same line


I know, it sounds rudimentary, but I don't want to make a mistake.
I have two dedicated power lines going to the same wall location, terminated with double outlet each. I need to add one more outlet to each of the two lines, so I'll have 4 total outlets connected to 2 lines.
I have replaced outlets before, so I do know how to do it, bu the wiring diagram, I'm not so sure about.
Thanks in advance

Be certain to connect the black(hot) wires to the brass colored screws and the white ones(neutral), to the nickle colored screws, so you don't reverse phase, between the outlets. Regarding the ground: just get some crimp-on, spade terminals and you can attach two wires(Romex ground and jumper) to your existing outlet's ground screw.
