There's a whore in my garden

We have a quite big garden, actually it looks more like a park...really green, wild with clear define stone paths, big threes, many places to hide but with some spots where we can be seen by some curious eyes... A place to realize some fantasies. One day at work my libido started taking over and my blood flowed to the wrong place so I could not concentrate anymore...I decided to send an sms to my wife..."Hi my dirty slut, put on a short skirt, do not wear anything under, wear some high heels and a shirt... go to the garden and wait for me somewhere there... I have some dirty plans for you tonight!!"... no answer. I then finished my day of work and went home... got into the house... no one there... my conclusion was: she did follow my instructions. Outside it was getting dark but enough light to be seen. Still wearing my elegant suit from work, I started walking through the garden... I could see her, waiting there against one of the massive three... smoking... she was in play role mode... She saw me approaching... and asked me if I would like to have some fun with her. I asked her for how much she would take for a blow and a fuck wherever I want... she replied that she does everything I want for a few euros and will enjoy it... the deal was done... my fantasy of having her playing the prostitute for me in our garden was going to happen!! I told her to go down. She kept her legs open... I could keep an eye on her just recent shaved pussy... she started pulling down my pants and started sucking my cock... licking my balls... I was hard as a rock... and she was really horny... this play role was driving us both crazy. She kept looking perversely at me while playing with me... I had a perfect deep view into her half open shirt where her nice tits were gently bouncing... I was more then ready for the next phase... and she could not wait any longer either... I decided then to pull her up by her hair and did turn her around against the three. I wanted to show her that I was the decision maker here... I did roll her skirt up and she did hold herself against the three.
