Flashed the maid

Just got back from a hot and sexy holiday. Plenty of sexy antics with the wife.
But what turned me on the most was flashing the maid. She was not much to look at, Turkish, in her fifties big breasts and only started looking at her differently when she bent over and I saw a black g string under her white trousers.
I deliberately used the bathroom while she was making the bed and came out flies open and clearly saw her look several times at my cock. Then she continued her work.
The next day we were on the balcony, I was sat facing in. She looked out and smiled. I pulled my cock down my shorts and exposed myself. She saw it. She kept looking over. I was growing in my hand and her stares became longer. She finihsed her work shortly after.
Was a huge turn on and shame I didnt see her again.
