M35 Recent experience at a bladder ultrasound scan.

NSFWNon-fiction Stories

I wanted to write about an experience I had a month ago.

I am currently battling pelvic floor dysfunction and I needed to have a bladder ultrasound scan at the hospital. They asked me to arrive with a full bladder. Specifically, they said to finish drinking a litre of water 1 hour before the appointment. Well, for me this sounded like a fun holding challenge. I thought I’d up it to two litres, 1 hour before the appointment.

On the way to the hospital on the train I felt the familiar fullness in my bladder, it felt really naughty that the train was packed with people, it was rush hour during the week. I was starting to fidget a little, but nothing too obvious. On arrival at the hospital I was told to wait for my name to be called. Now, uk hospitals are insanely busy during the week and I secretly knew I would be called late for my appointment. But this all added to the thrill of the experience. I was on those hard plastic chairs, squirming and crossing my legs at this point. I was trying my hardest not to look visibly desperate. I know the lady next to me saw my attempt to squeeze the end of my penis subtly through my trousers. Another half an hour went by and I started to wonder whether this was worth it. I was getting close to either having an unplanned accident or unleashing my stream in the toilet and having to book another scan. When I was finally called I was dancing from foot to foot trying to rush into the scan room.

To my delight/embarrassment the doctor completing the scan was a lovely, smiling, attractive woman. I was not expecting this. Usually the assistant is sometimes female, but never the scanner. She knew immediately that I was holding in a lot of piss. She said I look rather distressed and asked would I be able to hold it for the duration of the scan. The way she said it, wow! sat legs crossed in her tights and short hemmed uniform. I couldn’t believe it, I was shocked and nervous, I just muttered a “hopefully.” I got on the bed, and she applied the gel. It was cold and I felt a little twinge in my penis as she applied it over my bladder. I think my bladder thought this was the time for sweet release. She was absolutely amazed at how much I was holding in. She even commented as soon as she looked at the screen. “Oh my gosh, you’re absolutely full to the brim, you must be so uncomfortable Mr.” I was stunned. This had been my wildest fantasy but I had no idea it would come true so unexpectedly.

What happened next just blew my mind completely. She started taking her time with the scan, it was as if she was trying to slow the whole process down. I think she was testing my limits. she kept saying “nearly there Mr” in a condescending, yet soothing, professional tone. Part of me thinks that she was trying to make me have an accident. I would have been mortified with embarrassment but I think she truly wanted to see me squirm, battle and then be reduced to a frantic mess of desperation pissing all over the floor in front of her. Somehow I made it through. She urged me to go straight to the toilet opposite in the opposite room and “relieve myself.” I tried to walk out casually, but it was clear that I was making a beeline straight to into the cubicle. I just about got my penis out in time before thundering a thick, crystal clear jet of piss into the toilet water for the best part of a minute. The sound echoed so loudly I started to feel rather self conscious. I was breathing heavily and felt incredibly turned on by the whole situation.

When I went back into the room to have the next scan, (to assess whether I’d emptied my bladder completely) she said how impressed she was that I’d managed to hold that amount of urine before and during the scan. She said this with a wry smile which set my mind racing.

Thanks for reading. I’d be happy to talk further about similar experiences / fantasies. Just drop me a message anytime. Happy peeing everyone!
