The phrase "my sister, my spouse" comes from the Song of Solomon ("You have ravished my heart, my sister, my spouse. You have ravished my heart with one of thine eyes, with one chain of thy neck" -- Sos 4:9) and there is no incestuous connotation for the phrase. From the Jamieson-Fausset-Brown Bible Commentary, "By the term "sister," carnal ideas are excluded; the ardor of a spouse's love is combined with the purity of a sister's (Isa 54:5; compare Mr 3:35)."
This song seems to be about consuming love, healthy or not.
