I tensed a bit as I felt it; I was in a bit of shock.

I could feel the ball deeper inside me than I thought it would go.

"... maximum vaginal depth reached. Proceeding with cervical strain test, a mild discomfort may be felt..."

Without any further warning, the machine applied further pressure onto the rod and I felt the ball press up against whatever it was that was in it's way. I felt a mild stretching feeling, followed by a dull ache in my lower belly, that felt like the beginning of a cramp. I winced a little at the discomfort, but it didn't last long as the pressure was release. Slowly, the rod was extracted and I felt the ball creeping back down my vagina and then pop free. The rod drew back into the machine and the hatch closed.

"... vaginal exam completed. Vaginal depth reached was seven inches, and the cervical strain tested to have a high resistance.
