It was a sunny summer Saturday morning when the car and driver picked her up and whisked her out of the city and out into the countryside, finally crunching up a gravel driveway towards a small estate house set in its own ground.
Before they reached the main house, the car swung off to one side and pulled around to a separate set of stable buildings.  The car stopped and the driver spoke for the first time.
"Leave your bag in here and I'll pick you up later and get you home.  Head through that side door there." He indicates a very agricultural stable door. You step out of the day, hesitant to leave your bag and everything you'd normally have with you, and watch as the car drives away around the buildings. You pick your way across the grass, struggling a little in your low heels, the breeze whipping your yellow summer dress around your knees and finally make it across the concrete to the door. Everything is very quiet and still.
When you open the door and step into the stables, it's still very quiet, warm, and a little musky. There's a concrete floor, tack hanging on the walls, and individual corals for horses, some of which are occupied.  You take a few steps forward, looking around and seeing nobody before finally calling out.
"Hello? Anybody around? I'm, erm..." You trail off. You've no idea how to finish the sentence. "I'm here to get fucked? I'm the entertainment?  I got an invitation I couldn't turn down?"
Luckily before you have to say anything more a tall older gentleman comes around the corner, dressed for riding with black boots and a riding crop at his hip.
"You're here! Excellent! Just in the nick of time too, they're nearly back. Come on, hurry though, we've just got time to get you fitted out!"
Taking your hand he leads you further into the stables, and stops at an open coral.
"Let's have a look at you then," he says, lifting your chin up with his finger and peering down at you, then spins you round by the shoulders and cops a feel in a very businesslike manner. He cups your breast, squeezes your bum, and runs a hand up your bare leg, feeling the hem of your knickers.
"Very nice, very nice," he murmurs to himself, "The club always finds such lovely specimens."
Finally talking to you and not himself he says, "Slip those knickers off, you'll not need those, and step inside. Everything is waiting for you."
