Under a car

There aren't a lot of places left to hide so you find a vehicle with some height and silently slip underneath. The cold asphalt chills you, even through your clothes. As you catch a breath you slowly become aware of some unusual movement above you.

"What in the-"

Before you can finish your thought the entire bottom of the car vibrates obscenely and falls down on top of you.

It feels like a huge, thick rug has covered you completely, except this rug is entirely composed of some sort of living threads. The thin lifelike strands reach under absolutely everything, the machine doesn't even have to strip you to get what it is after. Millions of tiny vibrations engulf you, it's like nothing you have ever have imagined in your wildest dreams.

"Oh, fuck! Get off of me!" You manage to squeak out.

The machine ignores your plea and massages you both inside and out. The tiny threads feel amazing as they dance across your tits and even better, if possible, between your legs. Several hundred of them tickle your clit in rolling waves. Your first orgasm explodes from deep within you before you even realise it's coming leaving you weakened and greedy for more.

"Fuuuck me!" You moan. "Oh god, I'm cumming again!"

Your sweat and cum are absorbed by the machine, which seems to make it more powerful. The more times you climax the more intense the fucking gets.

By the time you finally pass out the only thing you still know is that you love the machines.
