Tim had known Joan for most of his life, she had been his Mum's best friend for as long as he could recall and he had grown very fond of 'Aunty Joan' as she became known over the years. He had never been sure of her exact age but he guessed she was now in her late-50's. She was a lovely woman, full-figured and attractive, with gorgeous legs, which she liked to accentuate with heels. She always dressed nicely and with a hint of something gorgeously feminine underneath. He had often found himself looking at her full bottom and speculating about her lingerie, she had a varying visible panty line and sometimes none at all evident. He found that as she got older she became more and more alluring.
Following the death of his Mum several years previously Joan had grown in his affection and he started to regard her in a different way. As a 19-year old Tim had lost his virginity to his landlady, a motherly 50-something, and he had grown a weakness for mature women ever since. Since turning 50 himself he found he was even more attracted to older ladies and had enjoyed wonderful sex with women in their 60s & 70s.
He loved meeting women who still craved sex in their senior years and found nothing more horny than a respectable older lady who enjoyed being a cum-slut in the bedroom. He loved the way they had no inhibitions and he especially enjoyed sex with married women who needed cock supplements in their lives. Sometimes their partners joined in, either to watch or partake to various degrees. Being bisexual he was happy to entertain any option.
He found himself fantasising about Aunty Joan more often and increasingly thought about her when masturbating. He still recalled the occasion when he had happened upon her in his Mum's house several years previously, adjusting the suspender clips on her fully fashioned nylons and had asked him to check her seams were straight. That had confirmed in his mind that he was a leg man! Since then they had often flirted together but Tim had always been concerned not to step over the line and spoil their relationship. However that all changed the day he showed off his new camper van to Aunty Joan.
Tim had bought the van as a way of getting out and pursuing his passion for the great outdoors, but since owning it he had found it a wonderful way of enjoying his other passion, namely older women who needed somewhere discrete to meet away from their husbands. So he was thrilled when Joan asked him to show it to her one sunny day, especially as she had been teasing him about it being his 'shag-wagon' as she called it. God, if only she knew, he thought. They arranged to meet at a nearby country park as Joan lived on a hill, and it would be easier to demonstrate the van on the flat. He couldn't help noticing that she had asked him to show how it was possible to unfold a double bed β she claimed she didn't believe it was possible other than in the biggest vehicles, but Tim couldn't help wondering if she had a hidden motive.
