Women have taken over the world. There are not many men left and the fertile specimens are kept in cages for breeding. Today, Miss Yara will take care of tapping the sperm. The subject is taken out of the cage and fixed on a bed. The milking is carried out as follows. First, the cock is stimulated for a long time to achieve the best sperm quality. Then it is further stimulated with pain to delay the orgasm even longer. This part does not serve to improve the quality of the sperm but is purely to satisfy the women's sadism. Yara visibly enjoys the misery of the sperm donor and even rubs herself against his face while he screams in pain. The sperm is then tapped out in the worst possible agony. The subject only wishes to return to the cage. There it is kept until it is needed again.
