Neffy, a fiery redhead, submits to her dominatrix, eager to transform into a human cow. Her mistress commands her to grow, and Neffy's breasts and ass swell, becoming massive and sensitive. She moos in delight as her nipples swell into udders, dripping with milk. The mistress teases her with a glass milking machine, attaching it to Neffy's engorged teats. The machine hums, pulling and sucking, drawing out a torrent of warm, creamy milk. Neffy, now a mooing, milking machine, begs for more, her body writhing in kinky pleasure.
