Narrative:

Upon arrival onto the ramp; captain informed me that the preflight was completed; clearance and ATIS received and that he was heading back to the FBO to print our flight plan. For this particular flight; I was the PF and [he] was the PNF. The passengers boarded. I performed my last exterior check only to find that the lav was still being serviced. Immediately afterwards; I completed the exterior check prior to closing the aircraft door. The taxi process was uneventful. [On] takeoff the [pilot monitoring] called out '80 kts cross check' and 'you have no speed'. ATC also warned us of traffic at about our 11 o'clock so my focus as pilot flying was outside. By the time I glanced at my instruments; V1 and vr had already been called. We proceeded to continue because we were heavy; max fuel and verified no annunciator panel light. I then transferred the copilot's air data computer (air data computer) data to my side. We continued the departure making a left turn climbing to 4000 ft. ATC vectored us to heading 320 degrees and asked us to climb to 6000 ft. At this point; the gear audio started ('gear gear') and we couldn't silence it. [Pilot monitoring] made a comment to the effect of 'I hope I didn't forget the pitot cover'. We also turned off the left pitot heat to avoid any damage in case it was still covered. We requested a vector back for a visual. We landed at a weight of 35;000 lbs (500 lbs over mlw) however; our descent upon touchdown was less than 200 FPM. No inspection was required. Upon reaching the ramp I got out of the aircraft and sure enough; the pitot cover was still on. Needless to say; even I missed this. The cover had been missing its red flag. I removed it; and proceeded with our departure.
