Cum quickly

You quickly cum, and a female doctor enters the room, she inspects the rubber vagina and makes a gesture of approval at the evidence of your obedience.
A group of nurses enters the room, and she orders them to prepare you for extraction in the lab.

You panic, but you can't resist, there are too many strong people holding you...
You are immobilized on the stretcher and transported to the laboratory.

Once inside, you are locked in a penis pillory. You panic, this wooden thing can destroy your penis, but you are just tied up and you can't move, it's not painful.

The mechanism closes with a powerful grip and you are frightened. The milking machine covers your penis, and it's like a cow milker. The rhythmic pulsations make your penis swell and after a few minutes, you have a strong urge to cum. You cum and your semen is collected in a vial.

The doctor watches with medical interest and explains that she has to collect only 20 more cumshots today and suggests you calm down and relax.

Unfortunately, no matter how much you beg, you are milked every day. After a few weeks with the machine and its special medications, your cock is swollen beyond your imagination, you have the biggest cock that you have ever seen, however, you are trapped in the machine, and you are reduced to a simple sperm producer.

You finish your days producing semen, with your penis so swollen and used that you don't feel any pleasure, you just want to rest and try to escape this nightmare... unfortunately, you are condemned and you will die here.

THE END
BAD END: Penis milking nightmare
