LAS VEGAS – Gamblers can bet on all kinds of things in Vegas. The latest action? Sex toy races.

According to the Huffington Post, “The new bar game, played by up to eight people, pits four battery-powered dildos against one another in a 1.5 mph race against the cock (had to be said).”

Here’s how sex toy races work: The vibrators have paper attached to the bottom of their shafts, allowing their vibrations to get traction on a table’s surface. When the race begins, all the vibrators are switched on at once, perhaps while someone shouts, “gentlemen, start your engines!”

In a forward-and-back jerking motion that makes one think of a politician changing campaign positions, the vibrators inch their way to the finish line. The one to get there first is the winner.

A video showing a sex toy race in action is available on YouTube . The excitement of the players as they root for their favorite vibrators to surge across the finish line is palpable (and so is the hip-hop music). Even the women — maybe especially the women — are excited to see which vibe cums first … that is, comes in first.

“It’s not the most cerebral game, but at least it’s more complex than Keno, and it gets people really riled up,” Frederic Walme told HuffPo. Walme is chief executive officer for Fun Factory, the sex toy manufacturer that sponsors the races.

The company also plans to host a race at the New York City Museum Of Sex, to raise money for an LGBT charity.
