The machine's hum grew louder, and I saw the dildo actually strain a little from the resistance of my cunt.

I knew it wasn't possible. The dildo failed to gain any ground in it's mission, but I heard the machine's hum grow even louder, and felt the pressure again increase, this time greatly.

"Shit!... Oh, AH! FUCK!" The machine was increasing the pressure every few seconds.

I gritted my teeth and muttered every profanity I knew. It was stretching my pussy to impossible limits. I could feel every advance the dildo made with my entire body.
