As I turn on the car engine my heart starts to beat faster. I'm driving down the road that marks the line between my life as dutiful wife and mother and my life as a wanton slut. By the time I stop the car outside your house the transformation is complete. I'm yours for the next 4 hours and ready to take whatever you will give me.

You open the door and pull me inside. I lean against the wall as you breathe into my ear and whisper "Ready to play?" I smile and nod. You return my smile and kiss me briefly, urgently before pulling away as you say "Then let us begin."

I have no idea what this means but the knowledge that you have something planned is thrilling. I feel my nipples hardening in my bra and the tingling surge in the base of my stomach. I long for you to take me to new places. I know you can.

It's a little unexpected but I'm prepared to go with the flow. "Yes please," I answer. "I think that's just what I need."

I try to stammer a reply but I'm shocked into silence. You've never spoken this way before. I thought we had an understanding. We've even laughed about me being yours 'on loan'. Then realisation dawns...

"Ready to play?" The words repeat in my head even as I feel your free hand grab my hair. You pull my head so that my ear is level with your mouth and growl, "I know exactly what a slut like you needs."

Fear and excitement fill me and my body responds. I feel defiant at your control. How dare you have such an effect on
