In mid May this year I had to have some time off of work for an operation, I came out of hospital after 6 days and was advised that I should take walks every day starting with a 10 min walk and progressing to 60 minute walks, well I had been walking for a week or so and if you remember this June, well the days were warm and sunny. On this particular day I woke up late about 11:00, and thought, no work to go to so why did I need to get up too early, the day was very warm and I thought why not go for a walk so I said to my wife I’m off for my walk. So I put on my shorts, shoes and a t-shirt and went to the wooded area behind our house. I’d been walking for 10 minutes or so when 50 yards in front of me, just standing on the path was a very slim girl of about 18 with a thin white t-shirt top on with spaghetti straps, a bright red denim mini skirt with a stripy belt, red sandals and what looked like from that distance sheer natural coloured tights, which struck me a quite strange as it was one of those hot hot days that we had in early June. As I approached I noticed that she had pert little breasts and that she had no bra on and her nipples were very erect As I got close she looked at me and said, “I’ve dropped my purse, would you mind helping me to look for it, I was running through the woods and dropped it in undergrowth?” I said, “No problem, where did abouts do you think you dropped it”. Pointing, she said, “Just back there the woods”. So we walked in to wooded area, which was much cooler than the path we had just left. We started to look around for it, but after a minute or so I could not find it, so I turned to her and said “Are you sure it was here that you dropped it?” She said, “Well it could have been it bit further back in the denser part of the woods” So I followed her deeper into the woods, as we walked I was aware that apart from a few birds singing there were no other sounds. By this time I was feeling a bit turned on, me a 56 year old male with only my shorts and t-shirt on and her about 18 wearing a skimpy top, a very mini mini skirt. We looked some more but couldn’t find the purse, so I turned round to her and said, I think we are wasting our time, it must be lost forever. To my utter amazement she said “Oh I don’t think we’ve been wasting our time at all, with that she came very close to me and started to rub my penis through my shorts, she then slightly streached the elastic of shorts and slipped her hands down and started to squeeze my semi erect penis. For a few seconds I didn’t know what I should do, but then I recovered and slipped my hands underneath her top, slid them upwards towards her breasts. As my hands covered her erect nipples she shivered, took her hands away from my penis and removed her top. I could now see that she had very small beautifully shaped breasts with large dark nipples which were standing erect as soldiers on parade. I bent my head forward and started to suck them and lick them with tongue. She put her hands back down my shorts and started to fondle my, by now, fully erect penis. After sucking and licking her breasts for some time I ran my hands down to her slim legs and slowly felt up her skirt, not that there was a long way to go as her mini only just covered her pert little arse. To my surprise she stopped me said, wait, with this she undid her belt, the button and zip of her skirt and dropped it to the ground, she was now standing there in a pair of sheer silky red knickers and what I could now see were sheer flesh coloured hold ups. By now my penis was fighting to escape from my shorts, she grabbed my shorts and quickly pulled them down, my cock sprang up like a spring, she dropped to her knees and took it her mouth, I, by this stage was quivering. She sucked and sucked until I was sure that I was going to cum in her mouth, but somehow she knew. She stopped and stood up and said "It’s your turn now". She slowly took off her silky red knickers and dropped them to the ground, I noticed that she had completely shaved her pussy, which only made my penis quiver even more. I got down and started to lick inside and around her vagina; she started panting as her clitoris got harder and harder. By now my tongue was darting in and out of her and she was grabbing my hair pushing me deeper inside of her. I was almost at the stage of exploding when she said “I would like to be fucked now”. With that she pulled away from me and walked back to where there was some soft green grass, with that she laid down on her back and said, “Fuck me please” I got between her legs and guided my penis towards her vagina and although it was by now dripping wet and I do not have a massive penis I found that I had to push really hard to enter her as I did I could feel her cunt muscles encircle and squeeze my penis, it was like having an rubber band tightening around it. By this time she was panting heavily and was gently pinching my nipples as I was sucking hers. My strokes started getting longer and longer and I could feel by balls beginning to contract, I’m going to cum I gasped, she breathed, me too and at that moment I exploded. We lay there for some minutes afterwards getting our breath back, then she go up collected her clothes and started to put them on, as she was putting her mini skirt she felt in the pocket and said, “ Look I’ve found my purse, isn’t that lucky and with that she walked out of the wood without even a backward glance. Me, I got dressed and walked back home, when I got in my wife said you've been a long time, you must have had a good walk in the sun!
