Diana is the chief employee of the "sperm bank". She goes to clients' houses and collects sperm. But for some reason this guy couldn't handle it himself. Diana reassured him and said that she would figure everything out. She quickly began to masturbate him, but it did not help. Then, the girl dragged a special sperm pump into the house. She put the nozzle on his cock and began to milk. The sensor on the sperm pump showed that the milking had begun, the sperm flowed. Enthusiastic, Diana proceeded with the procedure. The dumbfounded guy didn't say anything. She promised to come back again!
