I sat down on the strategically placed chair in my bedroom and eased my trousers and boxers down to my ankles, taking my semi-hard cock in my right hand, gently squeezing it, feeling it harden. I lifted my head, peering through the bottom of the window at the objects of my gaze. Two young women lay back on sun loungers in the neighbouring garden, both dressed in bikinis, their breasts straining against the bra like tops, their crotches visible between their parted legs.
I started to stroke myself, enjoying the feeling running through my body, my hand slipping over the crown of my cock with each upward stroke. They were both in their early twenties and I had known them for all of my life, the younger one and I had been born weeks apart and we had grown up together, as close as any siblings. Her name was Samantha, her older sister, by two years, Victoria, or Sam and Vicky as everyone called them. They were both very attractive with blondish hair, currently tied back in pony tails and had amazing figures, full breasts, shapely waists and legs that stretched forever.
It was unusual to see them both there, Vicky had a boyfriend with whom she lived about an hour's drive away, but Sam lived there with her Mum, her Dad having died a couple of years ago. I lived with my Dad, my mother having left us about four years earlier. I was aware that my parents were not getting on, but when they told me they were separating I was distraught, what I had believed to be a close knit family was breaking up, my mother having found someone else.
I stayed with my father, it was more practical, Mum and her new lover could only manage a small flat, and our family home was near to my school. Initially I was very bitter towards her, refusing to see her, but Dad sat me down one day and explained that she would always be my mother, no matter what the relationship between the two of them was. In fact he encouraged me to stay close to her, setting an example by steadfastly refusing to talk her down, even accepting that there were two sides to every story and he had to shoulder his fair share of the responsibility for their break-up.
So I used to see my mother as often as I could, and when she and her new man bought a house together, I did actually go and stay with them sometimes, but it wasn't home and I didn't really feel comfortable there. He was pleasant enough and he never tried too hard with me, so we got on fine.
My Dad was great, he treated me like an adult, we used to go and have a beer sometimes, usually after work, I had a job in a local Insurance company and we'd meet up in town and go for a pint and something to eat once a week or so, he even accepted me buying my round, but although he never tried to "manage" me, I always knew he was my Dad and would always be there for me as a Dad.
I was twenty-one and currently girlfriendless, I'd had a few, never really getting serious, enjoying sex with them, I'd always been attractive to the opposite sex for some unknown reason, and could always find an eye-catching companion, but I was certainly not looking to settle down for a few years yet.
Hence really I suppose, why I was sitting in my bedroom spying on my neighbours, masturbating briskly on a Saturday afternoon. Dad was out, the sun was shining and the two young women in the garden were certainly worthy of my attention. As I watched and wanked, my eyes travelled their bodies, wishing they were closer, I'd tried using binoculars in the past, but it really was too awkward and so I was thankful for my 20/20 vision and the convenient aspect of my bedroom window.
As I watched, Sam stretched her arms above her head, her top tight against her breasts and I wished they'd pop out, just for a second, but they stayed firmly ensconced. Vicky sat forwards and my attention switched to her, she spread her legs, bringing her knees up and peered down at her crotch as though examining for stray hairs, of which there were none I was sure, when I had used binoculars I couldn't see any through the 20x50 lenses.
Of course I felt a little guilty at spying on them in this manner, they were like sisters, but which brother hadn't tried to get a look at his sister's tits or pussy. I would have given my right arm to see either Sam's or Vicky's, well perhaps not, I discovered that I couldn't masturbate successfully with my left hand, and although it was rumoured to feel as though someone else was doing it, I was just not co-ordinated enough.
I was starting to get really into it, and was managing my arousal, forcing myself to slow down and speed up, I didn't want to cum too quickly, Dad wasn't due home for a while and I wanted to really enjoy this one, seeing both of them together was a rarity these days. Another figure came into view and I realised it was their mother, Jane, Aunty Jane to me, she'd been a second mother to me, as mine had been to the two girls, comforting me through scraped knees, nursing me through childhood illnesses and generally treating me as her own child.
She was dressed in shorts and a tee shirt, covering her ample figure, she wasn't seriously overweight by any means, just curvy and cuddly. She paused by the girls, clearly talking to them, then looking up at the sky, plonked herself down on a third lounger, and sitting up, pulled her tee shirt over her head. Now this wasn't the first time I'd seen her in a bra, I'd even seen her breasts once, many years ago, but the sudden sight of them was too much and I came, my cock spurting out into the hastily grabbed tissues that I had nearby for just such an eventuality.
As my orgasm rolled through me I could see them all looking up at my window and I hastily ducked down, I didn't think I could be seen, the angle and the refection should have taken care of that, but it was a little disconcerting nevertheless.
I thought I'd got away with it, then on Sunday morning there was a knock on the door. Dad was busy so I answered it to find Aunt Jane and Vicky on the doorstep. "Hi Billy, is your Dad in, we just wanted a quick word with you both if that's possible?" Aunt Jane and her daughters were the only ones outside the family to call me Billy, I was christened William and for many years was known as Billy, but now I was grown up I preferred to be Will.
"Sure, come in, is there a problem?" I asked tentatively.
"Hopefully not!" I went and found Dad and we settled down around a cup of tea at the kitchen table.
Aunt Jane started. "Well it's good news really, as you know Vicky and her boyfriend have been together for some time and have now decided to get married," I breathed a huge sigh of relief, "and want to do it while they're on holiday in September. They're going with some friends to Skiathos and have already booked." She turned to Dad. "The thing is we wondered if you would give her away in the absence of her father. It's not going to be a big do and you've been as close to us as anyone over the years and Billy is more like a family member, so he's invited as well."
Dad stood and pulled Vicky into a hug, "Vicky, congratulations, I'd be delighted." I added my congratulations and we all hugged.
"We'll need to work out the details, but perhaps the three of us and Sam could go out a bit after Vicky, and travel together. I'll do some research and let you know likely dates and we can sort it all out in more detail later. We chatted for a bit longer and then they left. About a week later we got a 'Save the Date' card for the middle of September which we stuck up on the fridge.
The more I thought about it the happier I got, both families had been close over the years, we'd had numerous days out over the summer holidays and had even been on a seaside holiday together once. Sam and I had been especially close, doing everything together until puberty started to push us apart, Sam's body developing, lumps and curves appearing as I became awkward.
