It all kind of went dark, I must've passed out because when I woke up couldn't move. At first I kind of panicked when I noticed my wrists and ankles were tied so tightly, but then I realized I had a gag and a mask over my mouth too. I was so confused and my mind was racing to figure out where I even was. A sudden buzzing hum like a motor switched on and jarred me out of my thoughts. At first I almost didn't connect what I heard with what I felt but suddenly that unmistakable warm flush from my crotch started to make its way up my body. It was such a strange mix of confusion, fear and intense sensation. Part of me was screaming let me out and the other part was hoping The ropes would keep me right where I was.

Cream started literally pouring out of me. It was almost too much, and for a moment I felt almost grateful that my ankles and wrists were tied down as tight as they were. Because it gave me something to push against while my body kept pumping out my cream until I wasn't sure how I was going to take anymore. The vibrations weren't stopping and my body kept going like a runaway train. By the time it had finished I was so sensitive and swollen that a gentle breeze felt almost too intense. I started noticing the room dimming and realized I had been pushed over my limits and was blacking out once more. I felt my clit just leaking as my thighs collapsed and I drifted off...
