The promise of an idle weekend was more than welcome after yet another long week at the office and I was looking forward to doing absolutely nothing.
As I started up the staircase that morning in search of that novel I had been meaning to read for quite a while now, I heard my wife's voice come echoing through the house as she called to me. "Honey? I'm going over to check on the kids! I'll be right back, okay?" She didn't wait for my answer either as that brief statement was followed immediately by the sound of the front door opening and closing.
I just smiled to myself.
Our next door neighbors had recently away on a second honeymoon and weren't due to return for at least another week, leaving behind their two children. Before leaving, they had asked my wife Latoya and I to keep an eye on the kids while they were away, clearly worried about wild and riotous parties that would leave their house wrecked. I didn't think they had anything to be worried about to be quite honest as Chris and Michelle Ayers seemed like such a well behaved pair, but I was perfectly happy to help my friend's out anyway.
Well, it was my wife Latoya who was doing all of the checking up on our neighbor's kids. She was constantly going next door to look in on the two of them and make sure they were not up to no good. She had even taken it upon herself to go and cook them at least one meal a day, saying that she was not going to let them try to subsist on fast food and frozen dinners. I did not dare say so out loud, but it was my opinion that her maternal instinct had been triggered and that she was enjoying pretending to be their mother.
Perhaps Latoya and I had made a mistake so long ago when we decided not to have any children of our own.
In any case, I had reached the landing at the top of the stairs when I happened to glance out the window that was there. This particular window provided a view of the Ayers' backyard, but it was somewhat limited by how the houses had been positioned. What had so caught my attention at that moment was the fact that Michelle was in her backyard in what I can only describe as a scandalously brief bikini. Her brother was out there with her, but in that instant I quite naturally only had eyes for the young woman.
With a luxuriant mane of blonde hair, sparkling green eyes, and full lips, Michelle Ayers had the face of an angel, but her body was definitely the work of the devil. Her breasts were a little on the small side, but seemed a perfect match for her slender figure, her legs were long and smooth, and her tight little butt looked as if it might have been sculpted by a master artist. All in all, she was a real life wet dream.
Also, since she was just an eighteen year old high school senior, she promised to get even hotter and sexier as time went by!
She was stretched out on one of those folding lawn chairs at the moment working on her tan and so I was able to get quite an eyeful since she was wearing practically nothing. As I lingered where I was to stare and drool and my cock started to stir to life inside my pants, I remembered that I was all alone in the house at the moment.
Perhaps it was due to the shock of seeing so much of the luscious vision next door, but I did not recall exactly why I was alone though.
Belatedly, I noticed that she was talking casually with her brother, who was standing next to her chair and gazing down at her with a smile.
Chris Ayers was a large and muscular young man about twenty years old, built like the football player he was. His hair was red and cut very short, his eyes were a clear blue, and he had a large roman nose. With a powerful physique like his and a college football player to boot, one might have been forgiven for stereotyping him as a dim-witted bully, but his warm nature, his ready smile, and his boyish freckles belied that notion. As he stood over his sister this morning, I saw that he was dressed in a simple T-shirt with his team's logo and a pair of shorts.
If his sister was a vision of feminine perfection, Chris was easily her masculine equivalent.
I couldn't hear what they were saying to each other of course, but in my mind she was complaining because he was blocking her sun and he was answering that she already had a nice rich tan and that she should get under cover before she starts to burn. I was to quickly discover just how wrong I was.
Even as I watched, Michelle sat up with a great big smile and pulled down the elastic waistband of her brother's shorts with one hand to pull out his already semi-hard cock with the other. She did this quite casually, I must say, hinting that this was not the first time she had taken hold of her brother like this, but I was positively stunned to see this teenaged girl take possession of the older boy's manhood.
Then, without even an instant's hesitation, Michelle pulled her brother's rapidly stiffening dick right up to her lips and went to work on it. Standing there in my own home and watching in shock as she slowly and sensuously licked his shaft and sucked on the bulbous head, my own cock quickly finished getting fully erect and I was compelled to release it from it's painful confinement in my jeans.
Isn't that an odd picture? A man standing on the second floor landing of his own home and slowly stroking his own cock while gazing down into the backyard next door where an act of incest was taking place.
As the shock began to wear off and my brain started working again, I was a little startled that the pair of them would do something like this out in the open, but then I remembered that their yard was shielded from the view of passers by thanks to a nice high wooden fence. Not only that, but the place they had chosen for their forbidden tryst really was completely invisible even from the upper floor of my house except from this one window - and even then you had to be standing in exactly the right spot to catch a glimpse of them. They probably thought they were completely safe from being observed where they were and they were almost right.
Michelle took her time, I must say, working slowly and quite professionally on her brother's manhood to get it as hard as possible. The skill this girl was showing was yet another hint that this was not exactly the first time those the siblings had gotten their hands on each other. I found myself wishing I had been paying more attention to what was going on next door - perhaps if I had this wouldn't be the first time I was able to enjoy a show like this.
As Chris grew more and more aroused, thoroughly enjoying his sister's efforts on his behalf, I saw him bend forward slightly to untie the thin straps that held together the top part of her bikini. It fell away to land in her lap and those firm young breasts were unleashed. They weren't porn star boobs and big enough to bounce or swing of course, but I was still treated to a wonderful little jiggle. She was blessed with large, dark nipples, I now saw, and I just ached to run my tongue over them.
By the time his sister had stopped nibbling on his cock and begun taking more and more of him into her mouth, he had reached down with one hand to cup one of those sweet little cupcake tits. His other hand was on the back of her head but I saw that even though he had taken hold of a fistful of her hair, he was not actually trying to push more of himself down her throat. No, he was letting her work at her own speed and I think all three of us were very happy about that.
Michelle was proving herself to be quite an accomplished deep throat artist and I was amazed to see just how much of her brother was disappearing into her mouth.
As I watched her head slowly move back and forth, my hand was going faster and faster on my own dick until I found just the right speed and rhythm. As my legs grew wobbly beneath me, I had to lean my shoulder up against the wall next to the window to keep from falling down since I was not about to stop beating off.
Chris was younger than I and clearly had a lot more stamina as he was still making the girl work for his cum when I was already growing close to shooting off. In fact, it would later seem to me that I was ready to cum awfully quick, but in my defense just let me remind you that I was standing there watching the wildest, the hottest, and the most unexpected sex show live and in person.
That's when it happened.
I was just about to reach my orgasm when the back door of the Ayers home opened and who should walk out to join the incestuous couple but my very own wife! In a flash, I suddenly remembered that the reason she wasn't at home right now was because she had been going next door. Knowing my conservative, church-going wife as I did, I was absolutely certain that she was going to be horrified by the scene she had just stumbled across and would read those kids the riot act. The show was over.
Fortunately though, I'd had just enough time before this interruption to finish what I was doing. Before the siblings could break apart in surprise at her sudden appearance and pretend that they hadn't really been fooling around, before my wife could start screaming about how wicked and sinful the act of incest was, I let out a deep groan and sent a stream of my pearly white seed splattering all over the window in front of me.
As I stood there and panted, trying to recover after my biggest orgasm in a very long time, I gradually started to notice something odd was happening next door.
