I felt the large, tapered end of the dildo press against my tiny asshole.

I felt the anal dildo press forward.

I felt my ass open only slightly around the tip. Just as when it entered, the machine increased it's pressure.

"AH!" I yelped. As the toy pushed harder into me. I felt my ass open only slightly but it still hurt.

The machine steadily increased the pressure.

"Gahhh! Oh shit... fuck it hurts," I grit my teeth and closed my eyes tightly. The stimulation of my pussy did almost nothing to lessen the pain that was shooting up through my ass.

The dildo crept slowly up into my ass.

"Ergh! Fuck!" I yelled. Out of instinct I tried to squirm my hips.

I could not tell how far it was progressing, but I could tell that it was getting thicker and thicker. My ass was on fire, as it slid deeper into me. The machine ramped up the pressure much more.

"AHHHHHHHHHHHHHHHHH!" I yelled as the last inch of it's tipped tore my asshole open.
