It wasn't a particularly busy or difficult day at work, but it was bloody hot. The weather had gone from a few weeks of nice clear days in the mid to high twenties, Celsius that is (that would be mid-seventies to eighties for those in the U.S). Then, out of the blue, we were hit with two days in a row of forty degrees (one hundred and five Fahrenheit). Hardly unheard of in Australia, to be sure, but it still kicks your ass when it hits. On top of that, it happened to be a day when I had to be at several house showings. I'm a real estate agent, so it meant that I was walking around in the heat for much of the day. The only respite was the air conditioning in the car.

On the drive home, I remembered that Zoe, my daughter, was working until later that night. I had been trying to work out what I was going to do for dinner because there was no way I was in the mood to cook tonight. The reminder that Zoe wouldn't be there triggered my memory that Patrick, my son, was supposed to be staying at his friend's place tonight, and of course, I knew that my husband Ben was away for work this week. He travelled interstate every couple of months for a week at a time. He had been doing this for the last five years, so we had gotten used to the routine.

I felt a small thrill of excitement that I would actually have the house to myself this evening, at least until Zoe got home after eleven. I wouldn't have to run around for anyone else or cook. I could make myself something simple to eat, have a wine and just relax in the pool all by myself and let the heat of the day leach out of my body.

That was when I had the exciting thought that I could even go skinny-dipping if I wanted to. It was something that I loved to do occasionally, and I always found it exciting; it just didn't happen very often. I could probably count on one hand the number of times it had happened since the kids were born, though, and they were both adults now.

That excitement of wandering across the backyard, completely naked, knowing that the only way the neighbours could see you was if they were deliberately trying to. Who knows, maybe they did like to sneak a look when they could. I didn't think that any of them would, but the thought was still a little exciting. Feeling the air caress your naked skin and then the water cooling you down and touching you in a way that felt strangely more intimate than just having a bath or shower. It was that feeling of heightened sensation that came with being naked, proved by the fact that even your bare feet seemed a little more sensitive to the grass underneath them when you had no clothes on.

I felt a shiver of anticipation move through me, and the fact that I was already horny just made it that bit more exciting. One weird side effect of the hot weather for me was that it never failed to make me ridiculously horny and summer was my husband's favourite time of year for exactly this reason. It had been the case for as long as I could remember. I don't know exactly why it did, but the combination of wearing as little as possible, feeling the heat on my skin and getting sweaty, always made me wet and horny.

It didn't help that the last client of the day was a very good-looking man in a beautifully tailored suit. Everything about him was yummy. His physique, how well that suit fitted him, the fact that despite the heat he was still immaculately groomed, and the expensive cologne that didn't quite mask the subtle smell of man sweat, which made me think of the smell of good sex. That raw, sweaty, fucking that left you with limbs of jelly.

I reached down between my thighs and let my hand slip under my skirt. I very lightly ran my fingertips over my panties, just giving my clit a very light tickle, as a tease of what's to come. My nipples were begging for some attention too, but they wouldn't be able to get anything more than a gentle tease until I got home, thanks to the bra and blouse I was wearing. I liked to be naked outside, but in the safe confines of my enclosed backyard, not in the car driving home. As exciting as that thought was, I had a professional appearance to upkeep.

I pulled into the driveway, grabbed my bag off the passenger seat and stepped out of my car. I was quite proud of my little car, it was nothing really flash, but it wasn't a base model either. It was the sports model with two doors, but I wouldn't go so far as to call it a genuine sports car. It was, by far, the fanciest car I had ever owned. I bought it after my first year of successful real estate sales. I had worked damn hard, not just for this car, but also for my position, as well as the success of the company that I worked for. I was no real estate mogul who would be making millions, not by a long shot, but I worked hard, and I brought home a nice salary.

My husband also brought home a good wage due to the fact that he had been instrumental in bringing the company he worked for from a devastated shell of a company, almost completely destroyed by the previous owner's illegal activities and gambling addiction, to a thriving sales success. He had worked damn hard for years and for several of those years he had been doing it for wages far below what he was entitled to. As a result, he had quadrupled the company's sales in the first two years for the new owners and it has been steadily growing since.

They knew he could have left and earned more years ago and it would have left them in a terrible position, yet he stayed. He remained loyal to the company and took real pride in his achievements. Turning it from a nightmare, running at a loss, into a multi-million dollar success story that continued to grow. The owners rewarded his loyalty and hard work with a wage that more accurately represented his efforts. We weren't wealthy by a lot of people's standards, but we were far from poor. We had been poor for long enough to appreciate what we had and not blow it on unnecessary crap.

The two exceptions I would say for me were this car, which was now five years old and would stay with me until it was no longer mechanically safe to keep, and the pool. We lashed out and got a lap pool, although it was wide enough to play volleyball in, installed in our back yard. I got the pool because I have been a swimmer my whole life and I hated the times when I didn't feel fit. Wanting to stay fit, and with teenage kids at the time, it felt like a justifiable extravagance.

I felt a very exciting tingle as I stepped out of the car and my pussy lips slipped across each other. My clit was already tingling in anticipation of that naked walk across the lawn and into the cool waters of the pool. My nipples were achingly hard and were demanding attention. I couldn't wait to get naked. In my head, I had already decided to wait until I was outside before I would touch myself. Tease myself by not touching where I desperately wanted to until I was outside, in the hot, summer, open air, before I finally slipped my fingers inside my needy little pussy.

I was grinning like a loon as I opened the front door. I walked through to the kitchen and felt the smile slide off my face as I heard music coming from the back yard. My handbag hit the bench, and my keys rattled next to them. I watched in disbelief as my son and his best friend walked past the window. They had no idea that I had arrived home yet and they were laughing at something.

I was pissed off. I felt completely irrational being angry at him. This was his home, and of course, he was always welcome here, but I was so wound up, and suddenly, nothing was going to happen. It's not like I could just go up to my room, strip naked and make myself cum with my son and his friend right here. I could feel the mood slipping and that was frustrating as hell. It was then that I saw two more of his friends wander past.

“For fuck sake. Can I please catch a break?”

I sighed heavily as I accepted the simple fact that my much-needed alone time just wasn't going to happen. I opened the door and walked out onto the deck. Patrick, my son, turned at the sound of the door. He still had a smile on his face and I tried to respond in kind but it felt forced. I watched as his smile slipped a little and felt a fresh wave of guilt at feeling annoyed at him.

“Hi, Mum.”

“Hi, mate. What's going on?”

I gestured broadly at the three boys sitting on the edge of the deck talking. Seemingly on cue, they all turned to face me with smiles, and I got a chorus of “Hi Mrs. D” from them all.

“Hi, boys.”

I couldn't keep the sigh out of my voice as I looked back at Patrick with a questioning look.

“Yeah, sorry, Mum. We had an unexpected change of plans. Seeing as it's so hot and we have the pool I kind of suggested that maybe here would be better. I'm sorry, I should have asked first.”

He was obviously picking up on my frustration levels, but it wasn't entirely his fault. I certainly didn't want him to feel unwelcome in his own home. I guess I just had to cop it on the chin. I made a mental note that he owed me big-time, though.

“It's fine, I was just looking forward to a quiet night.”

Yeah, a quiet night of being naked in the pool and playing with my incredibly wet pussy. I could feel myself blushing as the thought went through my mind, and I was grateful that my already hot face would help disguise the blush that I could feel creeping up my neck.

“Sorry, Mum.”

“It's alright, just try to keep the noise down. I don't want to upset the neighbours.”

He looked across at the sound system he had brought out from his room, but before he could say anything, I set him at ease.

“It's fine as it is, just don't have it too loud, okay?”

The smile he gave me was one that always made me give in to him.

“Thanks, Mum. I love you.”

The second half was said a little softer in the hopes that his friends wouldn't hear. He may be legally an adult, but he still had some of the habits from when he was a kid at school, and it made me smile.

“I love you too, Pat.”

I turned and walked inside, sighing again as I entered the air-conditioned space. I picked up my bag from the counter and proceeded upstairs to my bedroom. I dumped my bag and lay flat on the bed for a moment, sighing as the weight came off my feet. I even considered having a snooze, but two things stopped me. The first being that I could already feel the mattress heating up underneath me and the second was my pussy practically screaming for attention.

I contemplated having a cold shower to try and cool myself off but I knew that what I wanted to do was go for a swim. I stood up again after kicking my shoes off and walked over to the window that overlooked the back yard. I couldn't see the deck from here where I knew the boys would be sitting around talking shit. The swimming pool was glistening in the late afternoon sun and was calling to me.

“Fuck it! It's my pool, they're not going to keep me from it.”

I went to the drawers on the other side of the room and pulled out a one-piece bathing suit that I had purchased recently but hadn't worn yet. I laid it out on the bed and made sure that I had cut all the tags off it then began to get undressed. I was down to my underwear when I heard a sound from in the yard, so I walked back over to the window. The boys had taken their shirts off and were tossing a ball back and forth to each other. None were looking in my direction, but I had the sudden realisation that if they did, they would be able to see me standing here in my underwear. Well, they would at least be able to see the top half of me, anyway.

My first instinct was to move away from the window, but then I wondered if any of them would look up this way. I stood there for a little bit longer in just my bra and panties, which were a sodden mess by now.

It was exciting and I couldn't deny the effect it was having on me, watching these half-dressed young men run around the yard. I slid my panties down my thighs and glanced down at them. They were indeed a creamy mess and I knew I would have to have a wash before I put my bathers on. Standing there with no panties on, regardless of the fact that they couldn't see that far down my body, was incredibly exciting. My fingers began to wander through the short landing strip of pubic hair until they found the slippery folds of my pussy.

It didn't take long at all for the first tremors of a small orgasm to begin. It left me feeling even more daring and after double checking that none of them were actually looking this way I reached behind my back and popped the clasp of my bra. I held the cups in place for a moment before getting the courage to let it drop to the floor. I stood there for as long as I felt brave enough to, feeling my heart pound in my chest and the tingles began again in my pussy. It felt like I stood there on display for ages but it was probably no more than twenty seconds.

One of the boys, Zac, threw the ball wide and Josh ran to grab it and I watched as he picked the ball up and turned in what seemed like slow motion directly towards me. I darted to my left as quickly as I could. I don't think he saw me but there was definitely a split second there where he absolutely could have.

I stood there naked with my back now to the wall next to the window, nervously giggling like a school girl up to no good.

I went to the en-suite and proceeded to splash cool water on my face and used a wash cloth to clean myself up. Once I felt a little more presentable I went back to the room and, steering clear of the window, I put my new bathers on. I was surprised to find that they were a little firmer fitting than I had thought. It was odd, they were the same size and brand as the ones I usually got, but the hips were cut just a little higher, and they felt just a little bit tighter fitting than my old ones.

I went and inspected myself in the mirror and decided that maybe I was just feeling a little sensitive because they looked fine. In fact I quite liked the way they looked on me.

I grabbed my towel and made my way downstairs again. There was that awkward moment when I walked out the door and the conversation the boys were having dried up. It made me wonder what they had been talking about. Was it juicy gossip or just the usual inane stuff about computer games, sports, etc?

I could feel their eyes on me but I did my best to ignore the looks. Men are simple creatures and when something grabs their eye, they lose all understanding of subtlety. I know it can be a bit unnerving when men men just stare but after the first five seconds or so they seemed to recall where they were and who I was. The three friends all looked at Patrick as though expecting a rebuke from their friend but there was none coming. Not until Andy opened his big mouth, that is. Andy had always been a bit of a loudmouth and was apparently born with an excess of ego.

He was possibly the least shy person I had ever met. He had an overabundance of confidence and, through some random stroke of luck and extraordinary genes, he had the looks to go with it. It was particularly unfair for his friends who were all quite good-looking young men with fit, healthy bodies. Andy was just blessed to be that one step ahead of them all the time. Even with his inability to keep his mouth shut, he still managed to charm his way out of any potential awkwardness.

“Damn Mrs.D. You're looking mighty fine.”

I completely ignored the comment, even if it did send a tingle of excitement through my body. The other boys looked at Patrick as though he may pull out a gun and shoot him where he stood. Instead, he raised one eyebrow questioningly.

“Really, Andy?”

“Hey, sorry dude, but your mum is a regular MILF.”

“Enough.”

There was an edge of danger to his voice that I had...
