Narrative:

This was my first flight in a jet in 5 months due to covid. We were doing 6 full stop landings at ZZZ. After landing number 3 (I think) while still on the runway we were told by tower to contact ground. I didn't want to call ground while on the runway; so I opted to work on setting up the plane for the next takeoff.the FMS has to be re-programmed from scratch after each landing which is a lot of work. I was busy doing that and we taxied for 1/4 mile without calling ground. Tower reached out to us and asked our intentions.I was in a rush to get the FMS and plane reset for the next takeoff and forgot to call ground. I've never done multiple landings in this plane so this was a non-normal operation for me.next time I should not distract myself from contacting ground by doing other work.
