Aircraft X advised me that he would be flying VFR at a low altitude. He appeared to be following a typical flight path used by VFR aircraft in the area. The aircraft cut through the northern tip of [two airport's] airspace; which too is a common flight path and a common practice. As the aircraft neared [a visual waypoint]; one of the airport's tower controllers called my line to advise that one of their aircraft who was primary only had Aircraft X in sight. Controllers typically observe VFR fly through this northern tip of [their] airspace at low altitude many times a day; every day; without point outs. As this was no different than typical operations in the facility; I did not perceive that there was a problem; until the CIC notified me that Tower had called to report an airspace violation. In the future I will either instruct VFR aircraft to avoid this small section of airspace; or I will point out the aircraft to the appropriate tower before the aircraft enters the airspace.
TRACON controller reported aircraft conflicted with a towered airport's airspace.
