This happened as a result of a conversation with my husband. He told me about a girl he saw on the beach who was openly masturbating. It clearly aroused him, so I thought I would try it.
The park is massive. It used to form part of the grounds of a large country house now long-since demolished. The vast expanse of lawns and plants allows people to wander and just drink in the scenery. I had other ideas.
I found a natural incline that allowed me to sit with my back supported. I intended to masturbate outdoors and had dressed in a short loose skirt and panties. I don't wear, or need to wear a bra. (Still the same size I was when I was 13)
I had a few false starts. Somehow, I just couldn't get into the mood properly. Oh, it felt exciting to be outdoors, with my knees apart and my hand in my panties, but I wasn't getting anywhere and was about to give it up. Now, I love being screwed outdoors and I thought that jilling would be great.
Then a guy walked over to near where I was and lay on the grass face down and began reading. This gave me a second chance. He was hunky and I stared unashamedly at him as I eased my knees apart again and started to stroke over my panties. He glanced up and that made me want to put my hand inside. Again, he glanced, looking at me for longer this time. I stared back at him and tugged my panties aside and slipped a finger deep in me. There was no mistaking what I was doing and he lost all interest in his book. I masturbated until I felt an orgasm welling up between my legs. It felt raw, almost sharp and totally unlike my normal cums.
The guy had not taken his eyes from my crotch the whole time. I jerked my head over my shoulder to indicate an old summer house not far away. To my delight, he followed. It was locked, naturally, but round the back afforded us enough shelter. I told him that there would be no sex but at the same time, I got his cock out and started to jack him off. He lifted my skirt up and I aimed his cock at my panties as he shot his load.
Back home, I told my husband what I had done and he showed me what being shagged raw on the floor feels like.
He wants me to write about an incident I set up for him. (He thinks it was a pure coincidence, but it wasn't.)
