Lacey wakes up with a strange device between her legs. She's nude, and helpless - she submits willingly but as the device slowly and steadily increases the pain she begs for it to stop. The torment continues increasing, and as it gets worse and worse she loses the ability to even speak - just grunting and moaning and crying. Will it ever end?

*note - the fuck machine between my legs in this is NOT running - this is a fantasy about a 'machine' that's tormenting me with pain*
