Sexy horse gear ad has social media galloping

A Queensland horse riding gear outfitters has got social media bucking wild with its sexy 50 Shades of Grey inspired ad.

The raunchy clip produced by Horse Gear Outlet really captures many horse lovers' unbridled enthusiasm for the animals by taking an unexpected turn.

While a trainer tends to his horse he is spotted by four young fillies who he tries to woo by pouring water over his bare back and chest.

The ladies appear to take up the stud's advances and stride in wearing their riding attire and proceed to tie the man up to a chair.

Thinking he's won the Melbourne Cup, the bound man yields as the ladies pull down his trousers and one of the women hogties his ankles with his belt.

The ladies then do what they came to do and grab the whips and bridles.

But then they saddle up their horses and ride off into the night, leaving the crestfallen stallion tied to the chair in his underwear.

It must be one of those things that only horse lovers understand.

After viewing the ad more than 65,000 time in the past two days, many of the Facebook fans suggest they really love it — the gear that is.

"I'm pretty keen to do this ... For the gear of course," said one fan.
