Another song. More! The one that says 'Warning:' at the start!

The 'song' starts playing but it isn't a song. There's no beat, just a woman's voice saying, 'Depth: 1; Speed: 1' and the machine starting.

In near silence, the machine moves the toy forward and back just an inch, and very slowly. You start pushing back to feel a bit more, but shortly after the voice speaks again. 'Depth: 2; Speed: 2'

The motion picks up, going twice as fast and twice as far. It's still not quite as good as a good fuck should be though, certainly not as good as the songs. You let it run, hoping the acceleration will happen again, and are pleased when you hear, 'Depth: 3; Speed: 3.'

The device speeds up again, though still very slow, but at least the strokes are a bit deeper. It still feels like it's teasing you. You know it can go faster and harder than this.

'Depth: 4; Speed: 4'

Better. 4 inches of cock slide in and out of you at a rate that a human lover could match, though maybe not maintain quite so long.

'Depth: 5; Speed: 5'

Five inches of motion, two strokes a second. That's hundreds of inches of cock moving through your hole per minute. It doesn't have the verve of a human but makes up for it by being more powerful and steady than any human could.
