Mature woman expands and stretches the uterus at maximum by inserting a catheter into the cervix, inflates the catheter balloon to block the cervical canal, and then injects milk through a large syringe via the other way of the catheter. The injected milk will expand inside the uterus and fallopian tubes, producing an internal dilation of enormous proportions. To achieve maximum dilation of the uterus she must open little by little stretching the cervix to the maximum for which she will use different sex toys and gynecological instruments such as those used in medical hospitals. Before starting, she opens her pussy a little to show that she has been wearing a butt plug inserted into her cervix for many hours to keep it open all the time. Then she masturbates with 2 different glass dildos that when removed leaves the cervical canal clearly open. She then continues to use several german metal probes together while increasing the size of the probes. A huge crystal dildo with large balls will leave the cervix ready and massed to expand it. It's time to insert a catheter deep into the cervical canal and inflate the balloon so it can't come out. Once the balloon is inflated, she takes a huge syringe full of milk and injects it through the other tube of the catheter which will produce an expansion and stretching of the uterus as it cannot come out. This is the moment when she begins to pull the catheter tube very hard until she drags the catheter balloon out of her cervix causing a spectacular source of milk coming out of her uterus. She repeats the uterus inflation with the catheter so that you can see it and enjoy it in different ways.
