Narrative:

Upon departure from newark airport we proceeded wbound on a 300 degree heading. We were subsequently released from ATC control and proceeded toward our destination on a VFR transponder code. I was PF and captain was PNF who was familiar with the newark area but had not flown there recently. He told me to climb to 4500 ft MSL for our cruise. Upon reaching that altitude the captain recognized that we had climbed prematurely and were inside the outer shelf of newark class B airspace. I immediately descended and the flight proceeded without further incident. In the future, better preflight planning, and my not deferring to the captain's experience to ascertain my own positional awareness would have contributed significantly to preventing the situation.
