I hope somebody could write a story like this.
It could be a nudist mother and son while slow dancing in a sweet music and casual about a son having an eretion, The son being outbalanced and fell on his butt on the edge of the bed or sofa. causing the son pulling the mom with him and ended up accidentally impaling herself in his son's hard cock. They were both wide eyed with surprise.
Or a nudist family with a brother and sister play wrestling on the floor and the sister stradling her brother to get the best of him. The Mom enjoying watching them was a bit shocked and surprised wide eyed when she saw that the daughter accidentally impaled herself on the brother and saw how her son's cock glistened with pussy juice when the sister withdrew from her brother's cock. The mom pretending to scold her kids but smiling. The kids just laugh about it and told their mom that it was just an accident.
Or Mother and son coddles naked in bed or the mom could just be wearing short nighties with out panties with their legs entwined and suddenly the phone rings and both of them got surprised and both jerked at the same time and suddenly they realised that the son's cock is burried deep in the mother's pussy.
This could be somewhat an incest story with some humor in it.
