[Hoshino Darts] Milk Tasting (Mama Milk Bokujou) [MrBubbles]

Maya-kun has zero patience for his hopeless mother—especially when her impossibly swollen breasts are aching to be drained, and he'd rather drink his milk straight from the source with something other than his mouth. When a busty nun enters the household, a quick syringe dose turns her massive tits into the family's newest dairy supply, and before long she's chained up as 'Pochi,' strapped to a milking machine and treated like the pet she's become. A depraved ffm romp of incest and lactation where the family keeps growing—and so does the milk flow.
