The slime attaches to the girl's body and secretes an aphrodisiac, and absorbs the body fluids secreted by the girl (milk, love fluid, and dregs in the girl's anus) to grow her body. When all the very good nutrients that can be obtained from the girl's body (milk milk, love juice, and waste from the girl's anus) are consumed, the slime begins to dissolve and absorb the girl's body.
