Frau Doctor instructed me to milk this patient, who was in a straitjacket, really hard. Unfortunately, I'm not allowed to sit on this hard cock, I was forbidden to do so. So the sperm sample has to be taken purely by machine. But we want a LOT. So I also hang the poor, horny patient on the fucking machine and he gets a "blubbler" on his gas mask. Under difficult circumstances, everything that he has collected in his overflowing eggs is taken out. Will Frau Doctor be satisfied with that? *Role play: I'm playing a horny, naive blondie here.
