I had to have an ECHO ultrasound last year, and although I was given a gown and asked to strip from the waist up, the gown wasnt big enough, and I couldnt close it at the front, my breasts were bulging out from the front as I stood waiting to be called into the exam room.
The as I lay on the bed, the nurse just opened it up wide and begun the ultrasound exam after putting on lube on my chest and under my breasts.. that was quite embarrassing
The ultrasound was quite painful as she pushed the probe hard into my flesh, and I had to change positions and lay on my left side while she moved he probe under my breast, and being a large girl, she had to lift my right breast up, with one hand while using the probe with the other under my left breast.
I then had to sit up topless while she took some measurments with the probe..then she wiped the lube geel off with tissues, wiping under my breasts, and chest, including over my nipples as it had spread everywhere during the exam.
I found all of that quite embarrassing at the time, although midly arousing afterwards!
