Ally leaves an untested, potent lactation medicine in the living room, which the ever-naked and dominant Kelly immediately consumes, ignoring Ally's warnings about its unknown effects and potential addictiveness for the consumer. Driven by a desire to breastfeed her nineteen-year-old foster child, Kelly declares herself the test subject for the medicine and you, the foster child, as the official taster. After a moment of medical hesitation, the submissive Ally agrees to the arrangement, setting the stage for Kelly to feed you directly as the ultimate test of her newly induced lactation.
