Receptacles are set up for that purpose. There are two brass screws on one side of the receptacle, and two silver-colored screws on the other side.
The hot wire from the source or another outlet (Turn it OFF) comes into the box and one wire goes on each side of the receptacle, black to brass and white to sliver.
The wire feeding the other receptacle does the same, one wire to each side of the receptacle.
You can put two grounds on the green screw or splice the two grounds together and put a small piece of ground wire (jumper, pigtail sometimes called) from the splice to the green screw.
