I decided that it was a great day to take my daughters to the park. They are probably getting a little too old for it really, but they still enjoy it and as they are old enough to be responsible for themselves it means that I can have a nice walk and then perhaps take a book to read or just have some time alone with my thoughts while they play. It was a pleasantly warm summer afternoon and they were getting a bit bored in the house so we walked the ten minute journey to the park. They ran ahead and once I got there they were already on the swings and so I strolled around a bit and then watched them over the fence and enjoyed the warmth of the sun beating down on my back.

As I watched I heard someone behind me and a familiar voice said 'Do not move'. I felt his face nuzzle in to my neck as he kissed me and he pressed his body against me and I felt the shape of his cock pressing on my ass. Now I knew who it was and I pushed my ass out more and he reached his hands round and held my breasts, one in each as he spoke to me; 'I have been watching you ass ever since I entered the park gate and couldn't resist it.

He unwrapped his arms from round me then and was feeling his way under my short skirt. I could hardly believe he was doing this in such a public place but the whole idea of it was making me so horny that there was no way I was going to ask him to stop. His hands were working their way up my legs now. Fortunately there were not that many people around, just my children playing happily hardly noticing if I was there and a couple on a bench who were watching us. The fact that they were watching us was making me even more horny and by the time his exploring hands made their way between my legs, I knew he would find that my knickers were damp.

He was kissing the back of my neck now, those tiny soft kisses which make you shiver and I could feel my whole body starting to shudder as his hands explored further. He slipped just one finger inside my kickers and then another and another until his whole hand was trapped under the soft fabric. He ran his fingers up and down my wet slit and I pushed down on them trying to force him to push them inside me but he was not in a hurry. A quiet moan escaped my lips as I uncontrollably shuddered hard and I heard him laugh quietly to himself, knowing what power he had over me. I glanced across at the couple on the bench and they were blatantly staring at us and occasionally kissing and I knew that they were getting turned on watching us. I felt juices run down my leg at the thought of it.

Then I heard the noise of a zip and I knew that he was ready to give me what I needed. I lent right down over the low fence and pushed my ass out as hard as I could. He lifted my skirt a little and then pulled my knickers aside with one hand and guided himself inside me with the other. I gasped as his cock filled my aching hole and immediately shivered again as I came, pressing hard on his thick shaft. I heard him laugh again as he began to slowly thrust inside me and I imagined what the couple on the bench might be thinking as they got a fantastic view of what we were doing.

I knew that if I looked at them I would come again so I resisted and just enjoyed the pleasure of being filled my this luscious cock. I was soon increasing my pleasure as I rubbed my clit under my skirt. He was thrusting harder too and I knew that I needed to come soon or else he would have to withdraw before I had my final pleasure. I rubbed my clit more frantically and glanced at the couple who were kissing but somehow watching at the same time. I could feel their eyes looking at me as I panted quietly and rubbed hard, feeling my orgasm building and building and not wanting to let go until the last possible moment.

He was pushing inside me faster and faster and I couldn't believe he had held on for so long, then I heard a guttural groan and I knew he was close so I relaxed and allowed myself to come. Shudders of pleasure spread through my body and I knew the couple watching us would be able to see me physically shaking as I came. I could feel juices pouring out of me and I pushed his cock out of me with the force of my orgasm. I could feel him grab his cock under the shelter of my skirt and he rubbed it until he came, splashing come all over my legs and skirt.

When we were done, we lay on the grass to dry out my skirt and we I looked over to the bench but the couple had gone, they obviously needed to go somewhere more private to express their desires.
