Pentecost Sunday - so hot!

The day started again perfect. My wife gave me another damn hot footjob wearing dark brown stockings. No question that I blew my load on her nylon feet. Little later I drove to the train station to pick up her aunt, we've invited her to spent the day with us. Her aunt - she's a widow - is a hot mature, nice body, never wearing a bra and as my wife told me very demanding about sex when she was younger. Sometimes I think about....
So there I was in my car waiting for the train to arrive that auntie took. She must had missed a train. An app in my smartphone showed me the time when the next would arrive. Just wearing sporty shorts made it easy to access my dick so I took him out. Within seconds my dick was hard as rock and started to wank. I could have cum easily but I decided to hold it back with other things in my mind.
Now we are sitting in the backyard enjoying the hot sunny weather. She's is 1 meter next to me, wearing a sleeveless top and short pants. Of course she can't see what I write. I'm still wearing my polo shirt and the sporty pants. The temperature is about 33° C. I think it's time to go back inside, change for something appropriate and finish what I started. Aunties ballerina flats are also inside...
