After the huge response I got from the last two installments I am continuing the story from my third visit to the clinic. This like the other two is true it really did happen to me.
Another four weeks had past and I was now a total convert to pee play. Every day since my last visit to the clinic I would piss in my hands, piss on myself in the bath, and fill my panties every chance I could get and squeeze the pee into my mouth. Sometimes I would be at the shops and wet my panties and just walk around in them for the rest of the day. I had become very good at controlling my bladder and I loved the desperation. My husband still sexually satisfies me between clinic visits but still doesn't know about my fetish.
As before I arrived with 5 minutes to spare with a full bladder (I'm starting to get good at holding two litres of water). The clinic was empty except for Sandra and the office girl. Sandra walked up to me and dragged me to one side and told me, that the owner of the clinic was here today doing the ultra sounds as she needed to keep up with her practical side of the business. I was devastated I couldn't believe it I was so horny and wanted Sandra so bad I asked her what we could do. She said she would try and see if she could do it as it was the last one if the day. Just then the owner appeared and said "You must be Michelle go straight in". As I went into the room I heard Sandra asking if she could do the ultra sound, but the owner said no and asked her to lock up and finish off her paper work.
As the owner walked into the room I noticed Sandra peaking through the half open door with that look of sexual frustration, I had the same look. As the owner sat down I looked at her nametag it said her name was Jane. She was dressed in a lovely white blouse and black skirt. I found out later she was 40 years old and had built the clinic up from scratch. She is quite an attractive woman still with a tight body for her age, dark hair and green eyes. She asked me if I had any problems with my pregnancy, which I answered no too. She lowered the bed right down so It was at her waist height and asked me to lift my dress so she could get started. Luckily I had on a pair of white cotton panties today as I wanted Sandra to suck my piss through them, but that was not going to happen.
Jane lubed up my stomach and started to probe me with the sensor. She was a lot more forceful than Sandra and she liked to press it hard on my bladder. I pulled my legs up to relieve the pressure but I released a small squirt straight into my panties. The pain now was very real as Jane was pressing harder and another squirt escaped. The front of my panties were soaked and I could fell a puddle forming around my ass. I was squeezing my muscles trying to hold it in, I didn't want to piss everywhere in front of Jane. I could see Sandra every now and then poke her head in the door to see what was happening. A few more minutes had past and Jane said that we were finished and that everything was fine and the baby was doing well. I could see Sandra in the doorway pointing to the toilet giving me a sign. I asked Jane if I could go the toilet now and she said "Just let me clean off the lube on your stomach first".
