I had a walk into the park and it was a very quiet and peaceful time. I sat down on one of the many benches that lined the footpaths. I felt a stirring in my pants as I sat there alone. All I had on was a tee-shirt and sweatpants so I pulled the front of my sweatpants down a touch to allow my semi erect cock to see the daylight.
At that moment it began to fully erect and my shiny bell end looked massive sat there in my lap. I had a sneaky look around and there was still no one about so I spat on my shiny bell end and teased my cock to full erection and began to slowly wank it. Within a minute precum began to flow out of it so I massaged it all around my shiny bulbous bell end and my six inch shaft and slowly worked my fist up and down it.
I could hear womens voices and I looked up to see two women walking across the other side of the bowling green. I stopped wanking and held my cock out fully erect and imagined them taking turns to sit on my erect penis and take that bulbous bell end into each of their rectums then get off and suck it for me and they could bend over in front of me and I could lick their arse holes out and their pussies.
All this was too much excitement and I quietly cum into a tissue as they carried on walking completely unawares.
I hadnt had much chance to put the tissue into a bag and into my sweatpants pocket and make myself decent than a middle aged woman came walking by and looked at me and said good morning as she walked past without realising what spectacle she had just missed.
