In the year 2156 society is divided between two different classes the intelligent and the non intelligent. The intelligent live easy lives where they create different ways to make life better for the Intelligent. The unintelligent are slaves for manual labor, house maids, and sex objects. It is legal for the Intelligent to do what ever they what to the slave as long as they serve a purpose and are not killed. Beautiful intelligent are selected for light labor and sex. Some are maids or simple toys; but some are pets like cats, ponies, or cows. We still rely heavily on oil and other fuels to get around our small towns, if we need to go somewhere far away we take hydrogen powered helicopters, cars are an expensive luxury and many have to walk. A scientist came up with a mean of transportation using slaves, light machinery, and a lot of chemistry. Let me tell you how it works.

The slave has a chip in her brain that can control hornyness; a throttle on the cart controls her hornyness. The faster the cart moves the faster the dildo pumps, after a couple minutes of pulling the cart the slave figures out the harder she works the faster she will get to orgasm. The slave is also injected with hormones that make his (Or sometimes his) breasts swell, they are pierced and then wire lead up to the cart and the driver can drive the cart with the reigns.

The system works very well and soon these new vehicles will be the main method of transportation.
