In the middle of September this year during the few weeks that the national Covid lockdowns were relaxed there was a week of fine, warm sunny weather. I decided to take the opportunity to drive to Surrey from Norfolk to spend a few days with my sister and her family. As I left their house at lunchtime to start the drive back to Norfolk I remembered that there was a layby nearby that had a reputation as a well known dogging and cruising venue. I had never got around to stopping there before so I thought that as the weather was so good I might as well take a look. When I turned off the dual carriageway and drove into the layby I saw that there was a selection of other cars parked there. I sat watching from my car and saw several men leaving their cars and step over the small ditch and walk into the bushes. After a few more minutes I locked my car and followed them. I found that there was a well defined path running parallel to the main road with some smaller paths branching off into the hedgerows. I stayed on the main path for a few hundred yards, I saw a vague shape through some low bushes and when I moved closer I saw that it was a naked man sunbathing on a towel, when he saw me he started to stroke his semi erect cock then sat up and asked if I would like to join him. I made some excuse and continued my walk along the path. After walking for a few more minutes I saw a middle aged man standing behind some thick bushes with his shirt off, I was about to move on when I saw the top of a head of dark hair moving back and fore below his waist. I moved around the bushes and came behind him. This man was also naked on a towel and in front of him there was a younger, attractive topless woman on her knees with his erect cock in her mouth giving him a blowjob. The man turned to look at me and invited me to join them and come closer if I wanted to watch them. The woman could see me approaching but she continued sucking his cock. I was now standing only a few feet away from the both of them. He asked me what I thought of her technique, I said that she looked quite talented to me, he laughed and said that if I was lucky she might see to me next. She took her mouth off his cock and said that she had a better idea. She asked me to get my cock out , I didn't need to be asked twice and I quickly unclipped my belt and pushed my jeans and underpants down to my ankles. My cock was already hard and she reached out her hand to squeeze it. She took her mouth away from his cock and I replaced him in front of her so that I could slide mine between her lips. The man went behind her and lifted her short skirt up over her buttocks. He got on his knees, put his hands on her hips and pushed his cock into her fanny and began fucking her. While she was expertly sucking my cock I kept looking around making sure that we were not being watched. I was getting close to cumming and she must have realised that because she looked up at me and asked me not to cum in her mouth, a short time later a few seconds before I was about to cum I pulled out of her and with a couple of strokes with my hand I aimed several thick streams of spunk onto her naked breasts. She complimented me on my aim and the amount of cum I had deposited on her tits. I moved away and pulled up my jeans, she lowered her head onto the towel so that her arse was higher, the man was pounding his cock fast and hard into her then with a groan he gave one last thrust which almost pushed her flat onto the ground. He pulled his cock out of her with cum still dripping off it. The woman cried out to him that she was close to cumming and to use his fingers to finish her off. After a few seconds his fingers made her climax and she rolled over onto her back. She used the end of the towel to wipe my spunk off her breasts. I told them that I could see a man about a hundred yards away coming along on the path and they both quickly covered themselves. After he had passed I told them that I had to leave, they both said that they hoped to see me again.
