My son was getting married to a lovely girl. My wife and I were chuffed that he was finally settling down with a nice girl. The reception was a large affair. We had two large Marquees with a connecting section. The wedding breakfast was set up in the one and the other set up for a group and a disco. I had paid for all the drink and a few other things. Her parents paid for the food and a few other bits, including the field and club house on the site. My son and his wife to be, paid for the marquees. It was a fantastic day. The day before the rain fell all day and the afternoon on the day after it rained again. They were very lucky with the weather. The wedding went off without any hitches. There was a small problem afterwards, but I quickly sorted that out. The meal went well and then the band was playing. The couple did their first dance and everyone was surprised they had been for dancing lessons. The people were dancing and drinking and generally getting merry. Then my Daughter in Laws mother tripped on something and twisted her ankle and grazing her knee. I helped Pearl to my car where I had a first aid kit. She sat in the passenger seat I cleaned her knee with some sterile solution, then I dried it and put a plaster on her wounded knee. As I was doing this, her dress that had a very long split had fell either side of her legs, and from where I was squatted I could see all the way up the remaining part of her dress to her panties. There was a damp spot. She noticed that I was looking at her fanny through her panties. I couldn't help it, my cock stirred and was soon at full length. Leg sorted I helped her to stand up and the ankle although sore was ok. As she stood, she kissed me putting her tongue in my mouth. I instinctively put my tongue in her mouth and played tongue twisters with her. Her hand went to my cock and through the kiss she groaned into my mouth. I put my hands on her arse cheeks and pulled her tighter to me. Then she was pushing me away. I thought she had come to her senses. No she hadn't she wanted to go behind the club house. I followed her limping to the end of the building and just around the corner. Her hands were in my trousers and trying to undo my belt and zip. Then she was wanking my cock. I had her tits out the top of her dress and was kissing them as I started fingering her pussy inside her panties. We were kissing and playing as we heard the music and laughter and fun happening in the marquees. Pearl pulled away, had she come to her senses, no she stooped down and took her panties off. I took them from her. They were soak with her juices. She turned and lent on a window sill as stepped up and slipped my cock slowly in. Just at that moment Tina Turner blasted out "Simply the Best." I must admit at this moment Pearl was definitely the best as she thrust back to make sure that she had all my cock buried deep inside her. We fucked for some time and then she pulled of my cock and faced me wrapping her arms around my neck as she thrust her tongue back in my mouth. Her leg with the plaster came up and wrapped itself around me. I had to position my cock so that it slipped back into Pearl's pussy. We humped at each other as our tongues played. I took one of her tits in my hand whilst my other hand supported her leg and cupped her arse cheek.. We could hear another couple somewhere fucking, but had no idea who they were or quite where they were as it was pretty dark. Then Pearl was gasping for air and humping even harder. Then with a loud groan she came. It was but a few moment before I pumped my cum deep inside Pearl's pussy. We heard the other couple talking trying to work out who else was in the darkness fucking. I helped Pearl put her soaked panties back on and kissing her pussy as I helped her. Pearl put her tits back away. Then she hobbled back to the marquee where her husband found us and said that he had been looking for her. Pearl showed him the plaster on her knee and told him we had gone to my car for a plaster. He was fairly drunk and happy and he want off partying oblivious of the cum dripping out of his wife's pussy into her soaked panties. I have never spoken to Pearl about what happened between us, but she always gives me that knowing smile.
