Stop licking my face all over! Hahaha. Cut it out!
Literal
Face [object-を] sloppily lick-[negative-imperative-な]. Hahaha. Stop-[imperative-ろ] [casual-よ].
Almost certainly directed at a dog — the combination of べろべろ (wet, sloppy licking), laughter, and the playful tone gives it away. べろべろ is a mimetic for broad, wet licking (from べろ 'tongue'). The ~な negative imperative and bare 止めろ imperative are both casual commands; the laughter between them undercuts any real severity.
