As a brother and sister Nick and Alison had always been close when growing up, Nick being the older by two years. As children, teenagers and adults they had few secrets. As teenagers for each of them the other was their first glimpse of the opposite sex naked, without ever going too far they watched each other's body develop into adulthood. Seeing hair sprout, breasts develop and other signs that their bodies were developing. Then they both married and, like many siblings, saw each other less often.
Now they were both over fifty and within a short space of time they both found themselves on their own. All children having left home, Nick moved nearer to Alison and they started spending more time together, there always seemed to be odd jobs that she needed doing.
When the subject of a holiday came up it seemed natural that Alison and Nick would go together, after all none of the children wanted the same sort of holiday and they would prefer to go with their friends anyway. Soon a place was decided on, the right balance of beach, bars/restaurants and peace and quiet. A self-catering apartment seemed to be a good choice, meaning they could have a leisurely breakfast either in the apartment or going out to eat. The only problem was cost, the two-bedroom apartments being priced for families or four adults. Eventually the brother and sister agreed that a one-bedroom apartment with twin single beds would be fine, after all they weren't intending to spend much time in the apartment.
Soon the day came and they arrived at the resort, the apartment proved to be just what they needed. They quickly unpacked their clothes and took turns in the bathroom to change into costumes, before heading to the beach. Nick couldn't help noticing how nicely his sister filled her costume, despite what she would describe as her flabby bits, the costume showed off her shapely legs and body. Despite having children and a bit of middle age spread, Alison was still a very attractive woman. Nick had always kept fit and prided himself on the fact that he was still the same size and weight as he was when he got married, nearly 30 years before. He might now be going grey and his hair thinning but he ran and played squash regularly.
The couple spent the next couple of days enjoying their relaxing break, taking turns to change out of sight of each other. Though, as it was warm at night, Alison was wearing just a thin nightie to bed and on occasions Nick couldn't help noticing that some mornings she had kicked the covers off her bed giving a tantalising glimpse of her body. What he didn't realise was that his sister was also very aware of his body in his thin shorts at night and small swim shirts during the day.
On their third night there was big thunderstorm, Alison had always been scared of them as a child and Nick now discovered that she hadn't got over that fear. As a small child she had climbed into their parent's bed when there was a storm, sometimes when they were older she would climb in with big brother instead as her parents complained that she should have grown out of the fear. Alison found herself awake, shaking and unable to settle.
