sissy milk

Year 2205 In a world with food shortages, a milk produced by some sissys was discovered through genetic manipulation. It is highly nutritious and substantial, containing all the vitamins and minerals necessary for world hunger. Sissys must be stimulated by their milkers to produce milk. Farms have been established where sissys are stimulated three times a day by a male. It is estimated that for every liter of semen, sissys produce three liters of milk.
