Brand New World - extensive male milking [art of 2 characters, B/W] (Patreon)

Just a fantastic plot: The world after the cataclysm began to exist according to completely new strict rules. And some of them most directly affected men who had a big, burly physique. Specialized camps and research laboratories appeared, which, quite legally, carried out all kinds of tests and experiments. As well as obtaining biological raw materials, such as testosterone, high-quality proteins, glucose, and especially valuable male lactate.  Special detachments and factions of licensed hunters hunted down and delivered big men to concentration research centers. Which, among other things, were also food corporations. As time went on, there were fewer and fewer fat beefy guy at large, and the price of hunters increased. In turn, corporations and laboratories are trying to collect seed material and artificial reproduction, cloning attempts have not been successful and are considered not a natural product.
