First, your nipple sensitivity is drawn out by the contrasting stimuli of dryness and moisture. You experience the 'Dry Nipples', thoroughly tormented with fingers and tools, then move to 'Moist Nipples', where licking, lotion, and oil make you feel them deeply. This two-part work allows you to realistically enjoy the reactions and changes of the nipples through a subjective viewpoint, fixed camera, and close-up stimulation.
