I felt the machine press harder, and I panted.

My pussy expanded, and I felt the rounded tip slip deeper into my cunt.

"AHHHH!!" I yelled as my pussy finally accepted the fattest area of dildo. I winced from the agonizing strain I felt.

"Oh, fuck... Ah!" My pussy continued to stretch around the monster's head.

My cunt was on fire, the burning sensation in the ring of muscles was awful but the dildo dispassionately continued to impale me with its rubbery thickness...

There was no relief. The lips of my pussy remained strained by the enormous shaft of the dildo. The machine, with it's cold, indifferent persistence kept pressing the dildo forward. With the full girth of the object pressed passed my resistant lips, the machine's progress increased.

I could feel the little tip prying apart the sensitive inner walls of my pussy, and felt them continuously spread until they too ached and strained over the full width of the massive object. It sank deeper and deeper.

It continued grating into me, the massive shaft wedged in my flinching vagina.
