I was told that there was usually good action with older men at a public toilet about a 5 miles from my home so one sunday early evening I caught the bus and went looking. I got off the bus and started to walk toward the park where the toilet was located. As I entered the park it was just getting slightly dark and was very warm I first noticed two men wanking each other in some bushes but walked on a little further on I could see a man walking towards me and the toilets in the distance. As I approached the man he made it obvious he was up for fun as he rubbed his cock inside his trousers as I walked toward him. He was about 60 but slim and fit looking, just my type as I was just 18, blonde and very fit. All I was wearing was a track suit bottom and a tee shirt with no underwear. As I walked closer I could not help it and got a hard on which was obvious. He looked around him and seeing no one else was there he got his cock out and wanked it as I came up to him. It was a beautiful cock, long hard and slightly curved up. Not a word was said but I just bent over and took his cock in my mouth licking him with my tongue and coating it in saliva. When I stood up he just grabbed me by the arm and walked me into some dense bushes away from the path. It was just light enough to for him to watch me as I stripped off and stood naked in front of him. His eyes devoured my body and he commented that I had no body hair so I told him I liked it that way and so did most of the men I had so far been with. I wanted his cock so slowly wanked him as we talked. He asked me to do him a favour and pulled out a small bag from his jacket. Inside were undies. I smiled to myself as this was not the first time I had been asked to wear undies and I knew it had a powerful effect on undie lovers. I asked him to turn his back while I put them on and very quickly slipped on the suspender belt black seamed stockings and tiny panties. I struck a pose and told him to look. He grabbed his cock and wanked at the sight of me as I walked up and down. Then he knelt down and demanded my cock. As he sucked me and I stroked the back of his head I was aware of the other two men watching. I smiled at them but put my finger to my lips to ask them to be silent. they put their thumbs up and carried on wanking while watching. he man sucking me was grabbing my bum and feeling all over my stocking tops, he was really turning me on. He then spun me round and started to tongue me through the panties. After a few minutes of this heaven he stood up and I felt cold gel on my bum, then his fabulous cock found my hole. We both froze in the perfect position then he slowly pushed it right in. He stayed right up me and fucked me in little but hard movements, while slapping my bum and feeling over my back. I knew he would not last and I urged him on telling him I wanted his cum. He came inside me with a huge groan and kept pumping into me. He must have been really full as he seemed to cum for ages, then he just pulled out and quickly walked away without saying a word leaving me nearly cumming but high and dry. The other two men quickly came up to me and told me that had been so sexy to watch was I up for more. I said yes and they asked me to follow them into the loo. I put my shoes on and feeling very sexy walked with them in my undies the 400 yards to the loo. Just outside they stopped and told me several of their mates were there and to just walk in. I went in alone and found three older men playing with each other. One told me he was nearly cumming and begged me to finish him off. I took him in my mouth and almost instantly got a mouth full of cum. He left and as the first tow men came in I was being kissed by the other two. They got really turned on by the fact I had not swallowed and we swapped cum for a while as they both fingered me and wanked me. I told them I would cum soon if they did not stop so I was bent over the urinal as the first one slid his cock into me. He had a long hard cock and pulled it almost out before plunging into me again. It was heaven and I could feel myself getting near and as he started to orgasm in me my own cock started to spurt without any help from me it felt amazing and had never happened before. He pulled out and left I noticed a couple more men had arrived and asked them to wait but they all refused and kept groping me. I knelt down and let them fuck my mouth while I wanked others then almost by accident they all started to cum at the same time. One in my mouth and the other three just over my body and face. They all quickly left leaving me in undies with cum running all over the place and me feeling a million dollars. My night was made complete by a lovely old man who came in later and took me into the bushes and gently cleaned me up and then sucked me off again and wanked over my bum as he could not get it hard enough to fuck me. He had loads of cum even from a half hard cock and I loved he feel of it as I walked home.
