Milk leaks from a guy’s nipples, either in slow drips or full-on squirts, and the panels linger on wet chests and swollen pecs. It usually gets played as a kink thing where his partner suckles, licks, or milks him mid-fuck, with plenty of messy nipple play and shiny trails running down his torso. Sometimes it’s tied to transformation or hormone/pregnancy-style scenarios, but the focus stays on the milk and the stimulation.
