Breast vore:= Sucking the prey into one breast, through the nipple and absorb or melting them into milk. Unbirth:= swallowing the prey with the pussy, sucking them into the womb to either absorb or melt them into cum. Anal vore:= devouring the prey with the anal, pulling them into the stomach to digest them.
