At the time of this story, I was about 30 years old and at the peak of my virility; I had recently broken-up from a long-term relationship and feeling a little bruised by the experience, though I never felt lonely, as I've always had good mates around me, both male and female.
My mum used to take short holidays out-of-season at a quiet beach resort in Spain and as my dad was constantly working, she often used to share her apartment with Aunty Rachel. Rachel wasn't really my Aunty, but a very close friend of our family, herself divorced with no children, so the nickname "Aunty" seemed about right. She was a fine looking, mature woman in her early sixties and kept very fit and healthy for her age. She had mid-brown hair, which lightened a little in the sun and slight crows-feet around the eyes, for she was always sunning herself, giving her a lovely overall tan. Rachel was not slim, not fat, but curvaceous, with large boobs (I'd say D Cup) and a flattish tummy, a good sized bum with only a hint of cellulite; she went to the gym regularly and was in good shape for her age.
Because mum knew I was a little down in the dumps, she asked whether I wished to join her and Rachel for a few days relaxing in the sunshine, eating some healthy Mediterranean food and swimming in the warm sea - not a regular prospect for me when living in Scotland!
Up to then, I hadn't spent much time with Rachel, as I lived a long way from my parents, who were in the South of England. When I had met her while visiting my folks, she had always seemed very vivacious and friendly and I did like the look of her, having a bit of a penchant for mature women.
Their little apartment was on the first floor of a well-kept, but almost deserted block, quite up-market, as it had three large bedrooms all on-suite. We each had our own room and space, a cosy arrangement, where we could come and go doing our own thing. My mum, who was a bit of an amateur artist, was off painting really good water-colour paintings; Rachel liked to read books and generally relax in the sunshine, whilst I went off early morning nature and bird-watching, which has always been my special thing (love-making excluded).
Late one afternoon, mum was due to drive to a local beauty spot to paint a sunset and suggested that Rachel and I should perhaps go for a wander along the beach, as the weather was lovely.
We set out together heading westwards along the wide sandy beach, which was almost deserted, except for the odd dog walker. Rachel was dressed in a yellow and white striped bikini with her bottom half wrapped in a light blue sarong. I was wearing t-shirt and swimming shorts. We walked slowly besides each other chatting away warmed by the sun. At one stage, Rachel took my hand and so we strolled hand-in-hand like a couple, but this wasn't a surprise to me as she was naturally an affectionate person.
It was getting hot, so Rachel undid her sarong and so looking down at her bottom, I thought I'd compliment her by saying: "wow, even your bum is brown" while pulling down my own swim shorts at the back to show her my somewhat paler backside. "It's not just my bum that's brown" she said, reaching back to undo her bikini top and letting loose her large, tanned boobs. They were fully-bronzed indeed, sagging slightly, but otherwise perfect, with lovely dark brown nipples. "Take your shorts and t-shirt off" she said: "there's no-one around and you could do with getting some sun on your whiter bits". A little shy, I took off my shirt and pulled my shorts down, becoming totally naked beside her. My body was in good shape in those days though with a flat stomach and muscles defined from martial arts and the gym.
