Brunette milf fingers her mature pussy while I masturbate in front of her

So yesterday I went to the beach to relax. On getting there I met this sexy brunette milf just lying down on the sand very close to the sea. What drew my attention to her was the fact that she was naked. So I decided to stay close to her. A few minutes later she begins to finger her pussy, I did not want to be left behind so I stood and started jerking off right in front of her.
