I had left word for you that it would be today you would be my sub so you knew what to wear. When you came to the door you smiled then blushed. You weren't used to such a short skirt, especially with no underwear. The blouse was opened to show the cleavage of your firm breasts; while far from see through it restrained you nicely and showed when your nipples were erect. The sandals were light, easily removed.
"You look good," I said as we walked down the steps towards the car. You were relieved to get in and I turned, putting a hand on your thigh. "Today your body is mine. They are my breasts to do with as I will. My legs. My pussy. Do you understand?"
You nodded, your skin turning pink again a little. "You have to do exactly what I say otherwise you will displease me. You don't want to do that do you?"
"No," you whispered.
"No Sir."
You smiled. "No Sir," you repeated meekly.
"If I am displeased I will punish you in the way I see fit. I might decide to chastise you whether you have displeased me or not and you will accept that. Is that clear?"
"Yes Sir." You bit your top lip a little anxiously.
I started the car and said, "pull up your skirt, expose yourself as we drive."
I heard you gasp. "But someone might see -"
"Yes, that's the idea." I sat. "I'm waiting."
You blushed deeply and shuffled in your seat as the skirt was bunched around your waist.
"Spread your legs."
"Oh God," you whimpered and let your thighs fall open. My hand slid up your inner thigh my fingertips running through the dark hairs. "Soon we'll remove those," I said as I stroked your pussy, feeling dampness on my fingers already.
I drove off, into the centre of the city. At the first set of lights a cyclist went by and instinctively you closed your legs and tried to cover yourself up with your hands.
"Open your legs, keep your hands out of the way at all times," I commanded.
"Please -"
"You are displeasing me, is that what you want?"
I heard you draw a ragged breath and slowly expose yourself again. Two men walking by did a double take and whistled as we drove off. I drove around the city centre a little watching you blush and avert your eyes any time we slowed or stopped.
"Your punishment for not doing as you were told is to take off your sandals and put your feet up on the dash. Keep your legs spread. Slide two fingers in your pussy."
"Ohhh..." you wailed and were about to complain when you realised it would be a worse punishment still if you didn't.
"Quicker," I said as you moved slowly to comply. You were spread and your hand played on and in you as we approached the truck. As I drew alongside in traffic I honked my horn to attract the driver's attention. He let out a couple of blasts of his horn in appreciation as he saw you before we both began to drive off. I saw that despite your deep embarrassment you were sliding your wet fingers in and out of your sex eagerly now.
I glanced over a few times as you masturbated, watching your excitement grow.
"No coming unless I say so," I warned.
