At the time we were living on a five acre small holding just out side of Johannesburg. Late one Wednesday afternoon a car drove up to our house and a friendly lady in her forties approached us and requested that we complete the census form, stating that she would be back on Sunday around 13h00 to collect it again.
My wife and I, being the kinky people we are, decided that we were going to be naughty and have the lady catch us doing something sexual.
Well Sunday arrived and by 12h00 we were both walking around naked, afraid that we would not be ready for action when she arrived. With all the trees and shrubs in the garden we were reasonably semi private and we sat around in the back garden, horny as hell.
We got a fire lit to cook some meat, poured a drink, got out the garden chairs and made sure our clothes were in the bedroom, to force ourselves not to chicken out. Even if we decided not to do something sexual at the last minute, we would at least still be caught naked.
By 12h45 I was dripping pre cum and we kept touching each other and ourselves. It was absolute torture needing to get the action and having to wait for the right time. This was not the first time we were doing something planned but this just seemed big and extra exciting!
Eventually, at around 13h20 we heard and saw the car arrive. We hurriedly moved over to the spot we had decided would give the lady the best view. My wife got down on the grass in the doggy style position, I knelt down behind her, holding onto her sides and slid my throbbing hard-on into her sopping wet pussy and began pumping away.
A minute later we could see from the corner of our eye the lady hovering behind a large shrub, watching us getting our pleasure.
