Narrative:

VFR on flight from ZZZ3 airport to ZZZ1 airport, us. I inadvertently penetrated ZZZ5 class B airspace without checking NOTAMS or filing IFR flight plan. The latter flight perfectly legal prior to 09/tue/01. I realized the mistake and the seriousness of it after landing at ZZZ1, by the base operator staff. I received no phone call from ZZZ4 tower. I will certainly check NOTAMS and file IFR flight plan where indicated from now on.
