The thrill of an unplanned encounter to me is better than that of an arranged meeting. It has always been a fantasy of mine to encounter a fellow walker on the hills or in the forest and after conversation, get to grips with each others cocks. At home I'm having a new kitchen fitted and I'd arranged for a representative to call round to give an estimate. I'd forgotten the time and just returned from the gym when the doorbell rang. Dave was about 65, doing the job part time. I showed him the kitchen and apologised for being in shorts and a vest and trainers. He said he used to go to the gym many years ago and liked my shorts. He asked what make they were and I pulled out the waistband and tried to read the label but the writing was too small. I was aware of a sudden sexual tension as he bent down to have a look. I realised he was looking right down my shorts at my pubes and his face was inches from my cock. I took the plunge and said I'd take them off to get a better look at the label. Standing there in my underpants I handed the shorts to him and he said, I dont suppose you can tell me what make of your underpants are? I just took them off and handed them to him and that was that. He knelt in front of me and took my expanding cock in his mouth and before long I was on the edge. I told him this and he just kept sucking so I just let go in his mouth. I passed him some kitchen roll and he went to the loo to clean up. What an amazing and unplanned encounter.
