The rides were bad and Aircraft X asked to descend. My D-side called and requested control; but neglected to point the aircraft out to the underlying sector. I forgot about the shelf as well so I never double checked my D-side's work and I descended the aircraft. There is really no recommendations. The issues are a lack of competency on everyone's part. The D-side barely works as is; and I myself do not get enough quality time anymore because of the lack of traffic. Combined with a constant changing of sector configurations led to this issue.
Center Controller reported descending an aircraft into another Controller's airspace; thinking the D-Side had pointed the aircraft out.
