The pleasure was pushing me fast towards an orgasm, but the pain was yanking me back.

The dildo in my ass was getting deeper. The thrusts getting harder. My belly rippled with every thrust. My insides were being pulverized into paste.

"AH... AH... AH!" I screamed. I felt the pressure building in my gut.
"AHHHHHHHHHH! UHH!" I yelled as a tidal wave swept me away. For a moment, I blacked out, then found myself shivering and shaking, squirming against the restraints. I moaned and shook until I was weak, but I could not stop.

I was having convulsions. I gasped for breath. My mind could make no sense of it, it wanted it to stop yet go on. I was doing whatever I could to squirm my hips against the thrusting dildos.

"AH AH AH AH!" I was drifting in and out of consciousness.
