Public dildo fun in the park

We were enjoying a walk in the park of a castle and i showed to hubby that I had open lingerie under my dress. I was so excited that I couldn’t resist to start a risky masturbation. Luckily I always have a dildo in my purse. It makes me so horny to  do this in public and the risk of being caught adds so much to the excitement. What would you do if you see like this in the park?
