Woman who lives down below

Woman who lives down below
I few months ago I was in a naturist spa and saw the women who lives below us in our block of flats. At the time I was completely naked having just got out of the hot tub and she was topless with a towel tied around her waist. She saw me too as she gave a little wave and smiled. A few minutes later I came across her again in the sauna and this time she was completely naked too. It was so horny seeing her great titties with the nipples erect and her shaved pussy with landing strip just above! Unfortunately nothing else happened but I have pleasured myself many times since imagining what could have!
