Incest Sex Story: Chapter 4: Enjoying the Weather - Sometimes the best things come about unexpectedly. I'd been anticipating a rather boring Memorial Day weekend which only appeared to get worse when my dad invited me to visit his mother in Illinois. Then he invited my Aunt Linda and her daughter Kristen to join us and that changed everything!

While it may have still been May, the weather was gorgeous! Had I been back in Pittsburgh, no doubt I would have been taking full advantage of the warm sunshine to work on that summer tan, laying out on my dad’s deck in nothing but the tiniest thong bikini. I know some people like seeing an “all-over” tan on a girl because it implies that she runs around outside nude a lot, but I’ve always liked just a wee bit of a tan line. Not enough to show when wearing typical outfits and such - that looks silly. I mean such that when I undress, it’s almost like those most private areas of my body are highlighted, giving the impression to whoever is looking at me that they are seeing something that is not normally exposed. Seems a lot more erotic to me!
However ... I wasn’t in Pittsburgh and I didn’t have the privacy of my dad’s deck available so that left the small deck at the rear entrance to my grandmother’s house. It was like the complete opposite of back home - zero privacy to the point you almost had to strike up a conversation with the neighbors when they came out to their car so as not to seem rude. Another major problem was the damn tree. Well, it was nice for shade most of the time, but that same shade pretty much made the deck useless for tanning.
Kristen and I slept in pretty late, not getting up until after ten in the morning when my aunt finally decided it was time for us to be social and have some breakfast. I just threw on a nightshirt and Kristen used what looked to be one of my dad’s shirts (when had she gotten that?) and we emerged into the light still rubbing our eyes. It wasn’t like we were exposing ourselves or anything, but still I caught a glance between my grandmother and my aunt. It wasn’t much, but it as there if you knew what you were looking for.
After breakfast we washed up and put on our bikinis. I would classify mine as my “public tanning” versions. That meant while it covered more than my normal tanning bikini did, making it suitable for wearing to a public pool or beach without having to worry about getting tossed out for indecent exposure! On the other hand, it really wasn’t intended to actually SWIM in, or for that matter, even run around wearing as it was pretty flimsy and easily shifted out of place or up my butt crack. It would help to assure that I didn’t create TOO much of a tan line yet at the same time, wouldn’t embarrass my grandmother if the neighbors saw me, at least so I assumed.
Kristen had on a similar number but while mine was jet black, hers was girly pink. Personally, I thought the black would look better on me once I got a tan but for now, it contrasted sharply with my lighter skin tone. Hmmmmmm, I needed to get some sun!
By now it was well past noon and the bright sun was out, a beautiful warm day. We grabbed a few beach towels and headed out for the lawn, abandoning the deck as there were only small patches of sun that worked through the leaves. The grass was freshly mowed and it actually felt better laying down than the deck would have since my grandmother didn’t have any decent cushions.
There was nobody around that we could see but even so, it wasn’t like we were on a private deck back home so a little modesty was required. Besides, I think that that a few strategically-placed tan lines are actually sexier than an all- over tan. With an all-over tan, it’s obvious you lay out in the nude and the immediate thing that comes to mind is everyone in the world has seen her nude so what’s the big deal? With just the smallest of tan lines at my pussy and around my nipples, it’s like they highlight something that is “hidden” from view most of the times, like the guy is seeing something that most other guys haven’t. Of course, it’s all a matter of perception. An all-over tan may have been gained from a completely private location whereas the girl with the tan lines may show plenty of her body, just not in the sunlight, but in the end, perception is what counts, not reality.
With this bikini I had on, keeping it in place completely would have resulted in TOO much of a tan line, such that it might show depending on what clothes I wear. That, of course, is NOT desirable. Visible tan lines when you’re supposed to be “decent” just say you wear a conservative bikini. Thus once I was on my back, I loosened the ties and let the strings full to the side, leaving my back bare. My bottoms were pretty narrow in the back - it was the front area that they were covering a larger area, so left it as it was since most of it was between my ass cheeks anyway. Indeed, from a distance I suppose somebody would have to look close to realize I wasn’t bare-bottomed.
Kristen, as usual, wasn’t quite as concerned about neighborhood decorum. Not only did she loosen up her top, but the bottom as well, leaving her essentially lying nude on her stomach with her bikini underneath her. God she looked hot! I loved the feel of her tight little ass and her long thin legs were shaved smooth and glistened in the warm, sunlight.
“Need some lotion?” Kristen said, looking over at me.
Now if there was ever a clichÇ line, that had to be it. Almost as bad as “Gee, it’s hot in here, isn’t it?” Then again, I wasn’t complaining.
Kristen sat up, her bikini top hanging from her neck loosely, barely covering her nipples - although for the life of me I didn’t understand how it even managed to do that. It was like there was two-sided tape or something keeping it from moving totally off her boobs. Her bottoms feel away but she was kneeling besides me so it wasn’t like she was showing off her shaved pussy to anyone. It was ever-so-tempting to reach out between her legs and touch that cute little thing but I just laid there, waiting for the feel of her hands on me.
The suntan oil felt a little cold at first on y sun-warmed skin but it quickly warmed as she spread it all over me. I moved my legs apart to allow her to get between them and she didn’t waste the opportunity to reach right up to my crotch where she moved my bikini out of the way and oiled my pussy. I couldn’t help but jump a little as her oiled finger easily slid into me.
“Kristen...,” I warned her, trying to remind her where we were.
“Oh you can be such a fuddy dud sometimes Kelly,” she mocked me, pushing another finger in me as if to prove to me she didn’t care WHERE we were at all. “Don’t EVEN try to tell me you don’t like it.”
Well, she had me there. Even though nobody was around, having my cousin fucking my pussy with her slippery fingers DID feel naughty and nice. With her other hand she massaged my butt, rubbing the oil between my ass cheeks and all over me from there.
“God you’re such a slut,” I sighed, trying to pretend to be exasperated at her continuing efforts.
“Hey, who’s the slut here? I’m not the one laying out in public all but naked getting my cunt fingered!” she came back at me.
I guess I could have reminded her that while I may be laying down all but nude, it was her that sitting up all but naked with her boobs clearly showing underneath the all but invisible bikini top. There was also the point that while I may be getting my pussy fingered, whose fingers were doing the fingering? Then again, why bother arguing?
“God that feels good,” I moaned softly, closing my eyes as I just laid there enjoying Kristen’s touch.
My cousin had one finger in me with another outside, rubbing up and down my pussy slit, hitting my clit each time as she moved her hand in and out of my crotch. The oil made everything so slick, it felt great! I noticed her one had had stopped fondling my ass and I opened my eyes just enough to see what she was doing. Sure enough, she had moved her hand to between her own legs where she was working her own pussy as she did mine. Damn, Kristen was really horny today! OF course, so what was new about that?
“Ohhhhhh, just like that, I sighed as she touched me right where it felt the best. It was like the sun had just gone nova or something as I started to feel hot all over, even inside of me. Kristen was fingering me non-stop, relentlessly pushing me over the edge.
“Oh god ... YES!” I moaned as my hips arched upward and into her hand. God, it felt incredible as I came.
Kristen pushed a second finger into me again, fucking me hard with her hand as she giggled. It was like she thought it was funny that she could drive me this would so fast. Well, if there was one girl who knew what it took to set me off, it was my cousin.
As I peeked and then slowly came down from my high, Kristen kept her fingers in me, just holding them inside of me the way a guy would keep his dick in me after cumming inside of me. She laid down next to me, her arm over my thigh as she kept her hand in place.
“You like my fingers in you Kelly?” she whispered to me softly, seductively.
Well duh! Did I really have to answer that? I just sighed and opened my eyes to look into hers, smiling at her as my body tingled all over from the residuals of my orgasm.
“Imagine if Grandma could see us now?” she teased me, giggling again like a little schoolgirl.
“Yeah right, like THAT would go over like a ton of bricks,” I sighed, not even able to work up a decent answer as I just laid there and felt her fingers twitching inside of me.
I suppose I would have returned the favor given a little more time to soak in the final few pleasurable moments I was having but it was then I heard a door opening from the house next door. Thankfully Kristen has enough sense to pull her hand from my pussy - as much as I would have loved for her to keep it there. We both laid there on our stomachs, just inches apart, essentially nude although all anyone would have seen looking at us were our bare butts and it’s not like there would have been hidden much more had we had our thong bottoms on.
“It’s their daughter.” Kristen informed me, her head turned to the side so she could see who was coming out of the house. She was blocking my view so unless I picked myself up I had to depend on Kristen to keep me informed.
“Wow, she’s certainly grown up,” Kristen said in a sultry voice, “She must be what, eighteen now?”
The couple next to us (the ones with the pool) had only one daughter. The last time I had seen her was years ago when she was probably still in grade school. Grandma had mentioned something her graduating this year so I guess that would make her seventeen or eighteen.
“What’s she doing?” I asked, curious now as to what was happening.
“She’s in her bikini - not bad by the way. Fuckin’ hot actually. Looks like she’s going swimming.”
With my curiosity now overwhelming me, I picked my head up enough to see over Kristen’s head. Damn, she wasn’t kidding. That little girl next door was HOT! A dark brunette, she wasn’t tanned at all yet and was wearing a skimpy white bikini that showed off her body without being TOO revealing. I suppose later when she had more of a tan the white color would make for a nice contrast but for now it only emphasized her pale skin. Not that it looked bad, mind you. She never looked our way once. If she HAD noticed the two of us, she was doing a damn fine job of pretending she hadn’t.
Both Kristen and watched (stared may be a better description) as the teenager opened up the gate to the pool, climbed up the steps and started working on removing the solar cover. Both of us sucked in our breath when she leaned over without bending her legs, showing off her incredible ass as the bikini pulled up tight between her butt cheeks. She wasn’t wearing a thong but the bottoms she had on still left very little to the imagination. She just pulled the cover to one side, not getting it completely off the pool as it appeared to be rather heavy and cumbersome. Then without further ado she jumped in and for a moment I thought of how cold the water had to be and was waiting for the inevitable gasp; but evidently the solar cover had done a better job than I’d anticipated as not a sound came from the pool.
Instead, what surprised me was to see first the top, then the bottom of her bikini being tossed onto the walkway around the pool. Damn, our sexy neighbor was skinny dipping! You really couldn’t see her because the water level was below the walkway and thus unless you were right next to the pool it virtually otherwise impossible to see anything in the water. It was sort of cool in that I hadn’t realized before now that even though it was out in the open, the pool was actually quite private so long as you stayed below or just barely on top of the water.
“Do you think she noticed we were out here?” Kristen whispered to me.
I shook my head together with a barely audible grunt that was meant to convey that I didn’t think she had, not with the two of us laying on the ground and the manner in which she had walked straight out of the house to the pool without even looking our way. I imagine knowing it was just my grandmother next door, she didn’t pay a whole lot of attention to the goings on in her neighbor’s back yard. Actually, if I’d been in her place I probably would’ve done the same. After all, even if someone WAS looking it would be just be an old grandmother who probably would have disapproved of my bikini so why give her the satisfaction of seeing her looking at me that way?
“Hey, what do you say we join her?” Kristen suggested.
I gave it a thought before I answered. After all, it wouldn’t be like we would be pursuing some kid as the girl WAS eighteen, or least close to it if not maybe even older. In addition, there was no sign that anyone else was home next door. The garage door was open and there was no car in it or parked on the driveway.
“C’mon! Let’s do it!” Kristen urged me as she tied up her bikini and gathered up her towel.
Oh what the heck, why not? I quickly tied and adjusted my bikini, grabbed my own towel, and walked quickly to catch up with her. As we approached the pool I had to wonder how the girl might react to having two strangers suddenly pop in on her while she was swimming naked!
As it turned out, she wasn’t SWIMMING naked, but she WAS indeed nude. When we got to the edge of the pool, I could peek through the fencing around it and see that she was lying on her stomach on an air mattress towards the opposite side. Her head was turned to the side, facing away from us, and she was lying there motionless, almost as if she was sleeping. With the blazing hot sun and her pale skin, I hoped that she had on some pretty good SPF sunscreen or she’d be paying for this later!
Kristen, ever the more outward one, didn’t hesitate. She climbed the steps and stood at the top, grinning back at me as if pleased with herself that she was the first to be there. Then she turned back to the pool.
“H!” she called out to the girl, “My name’s Kristen and this is my cousin Kelly. We’re visiting our grandmother next door.”
The poor girl must have either been asleep or pretty well out of it as at the sound of Kristen’s voice her head popped up and she twisted so quickly that she fell off the air mattress and into the water. Gathering her senses as she stood up in the pool, she quickly got behind the mattress, using it to shield her nudity from whatever intruders were there. Her eyes were about popping out of her head as she looked at Kristen, then me, and back to Kristen again, a picture of uncertainty painted on her face.
“Sorry, didn’t mean to scare you, can we join you?” Kristen went on, as if nothing had happened.
The girl just stared at us, as if too frightened to reply. I don’t think she still had quite figured out who it was that was violating her privacy. Well, if she was surprised at our entrance, imagine her surprise when Kristen simply stripped off her bikini and jumped in. Figuring that nothing much I did now would make a difference, I quickly undid mine and joined them.
So much for the efficiency of solar covers! Damn the water was COLD! I could feel my nipples instantly harden and goose bumps raised all over me as the initial shock sank in. It wasn’t really THAT bad, but colder than I had anticipated so that made it seem worse than it was at first. By the time I’d gathered my wits and cleared the heavily chlorinated water from my burning eyes, I saw Kristen had already made her way over to the air mattress on the opposite side from the girl who was still staring at us, speechless.
