This is my first submission here, so go easy on me. I started a series on another site, but they have since shut down their incest section, so here's what I had already. If it's received well here, I'll keep it going. Enjoy!
Part 1
The first drop landed on my left cheek, startling me from my slumber, and the next drop a few seconds later caused me to sigh out of tired frustration as I slipped out of my bed. You see, for the past couple of years, our roof would leak sometimes when we got really bad downpours during the summer, but it generally only affected me, because it only leaked into my bedroom, and to make it worse, it leaked right over my bed where my head would lay. My parents had had a few different roof repairmen come and take a look, and no one could find the leak. So on those nights, I had no choice but to replace my pillow with a bucket and sleep on the couch in the living room.
Let me tell you a little about my family before I go on. My name is Sam Smith Jr. and I'm the middle child of three. I'm about 5'7", a little on the skinny side, but toned from being very active. I have dark brown hair which I keep short and brown eyes to match. My mom, Carol, is a 2nd grade teacher and she has just recently crossed into her 40's, but with a beautiful, wrinkle-free face, long blonde hair, green eyes and a tight little 5'3" frame, she still looks closer to 30. My dad, Sam Smith Sr. is an accountant, with dark wavy hair and eyes like me, around 5'10" and a solid body better than most other 45-year-old men. They are both genuinely great, loving parents, though my father does get a little too caught up in his work sometimes.
I have two sisters close to me in age, Amy and Kim, both of whom epitomize the girl next door. Amy just turned twenty-two, and she looks just like our mom, except younger and more petite, but with the same perfectly shaped beautiful face, with plump red lips and the same amazing green eyes. She does almost nothing to take care of her body, but can't be more than a hundred pounds, standing only 5'2", but with amazing curves. Her 34C breasts look enormous on her tiny body and her plump, round ass, stuck between a tiny waist and pair of firm, skinny thighs, always looked amazing.
On the other hand, Kim takes after my father in most ways. She's eighteen, but already a little taller than Amy. They have the same size chest, but Kim has a little more meat on her bones. Her ass is even rounder than our sister's, her hips a little thicker, and her legs are more toned from being on the soccer team and running recreationally year-round. Kim has an adorable face, with a cute little nose, a sexy set of thin, pink lips, and light brown eyes, all accentuated by her raven black hair which is incredibly curly and reaches just to her shoulders, framing her face perfectly.
I had always been aware of and even been attracted to the cuteness of my little sister and the hotness of my older sister (and my mother, for that matter), but I never expected anything to manifest from it.
That brings us back to earlier tonight, when I had to vacate my bed because of the ill-positioned and ill-timed leak. I gathered my covers into a ball which I stuffed under my arm and in my other hand I carried my smartphone, which, as is the case with all teenagers nowadays, is never more than a couple feet away from me. I liked to sleep naked, but now that I'd have to sleep on the couch, I had to bring a pair of shorts to put on before getting out from under the covers in the morning, just in case. I didn't bother putting them on though, since it was after 1 AM, and I figured everyone would be fast asleep by now. In fact, as soon as I got out of my room and into the hallway, I tried to be as quiet as possible as not to wake anyone. My parents' master bedroom is on the first floor, but both my sisters' rooms are on the top floor with mine, though I was at the end of the hall, so I'd have to pass both their doors.
As I got closer to Amy's room, I realized that her door was open a couple inches, and that she had her small bedside lamp on. I immediately assumed she was up late reading, which was not out of character for her, but when I paused at the perfect spot so I could see her bed through the small gap, my eyes widened and my jaw dropped out of surprise. Amy was indeed in bed, but with her was Kim in a pair of tiny purple shorts that left half of her ass showing and an old tattered white tank top that she had been wearing as a night shirt for years, and it showed off her perky, ample breasts well ever since she had started filling out. Amy looked even sexier wearing just a little black lace nighty, which cut deep between her breasts and barely reached the top of her round, firm ass cheeks.
Their bodies were entwined in the sexiest manner possible- Kim was on the bottom, with her legs wrapped around her older sister's waist, one arm around her shoulders and neck, and the other much lower, squeezing and fondling Amy's round, bare ass, and I could see her fingertips slide up and down Amy's slit from time to time. Amy was laying on top of her little sister, grinding her hips down into Kim's. While one arm kept her upper body supported, her free hand roamed her sister's body passionately, going from squeezing her breasts and teasing the nipples down to her hips which she grasped tightly and pulled against her own body, creating extra contact between her bucking hips and Kim's thinly-veiled crotch. This elicited a throaty moan from Kim, though it was mostly muffled by Amy's mouth, since their lips and tongues were joined in one of the hottest kisses ever.
I stood there naked in the hallway and watched for a couple minutes, with my jaw hanging wide open and my cock harder than I could ever remember it being. Normally I'm about seven inches long, but I felt so hard and the head was so swollen that I'm sure it would've measured at least a quarter of an inch longer that night. My comforter was now on the floor by my feet along with the pair of shorts I had brought to be decent in the morning. I wasn't really worried about getting caught, since I knew they would have trouble seeing into the dark hallway from their spot in the dimly lit room, so I continued to watch my sisters go at it fervidly while my left hand squeezed and gently rubbed my aching hard on.
Suddenly I became aware of my phone in my right hand. Without really thinking and in almost no time at all, I had it recording the incestuous scene. And I started recording just in time, too; Amy gripped the hem of her black nightie on both sides of her hips and lifted it up and over her head, then tossed it carelessly on the floor next to the bed.
I was viewing them from behind, but at an angle, so I could see enough of my older sister's naked breasts to make my cock throb wantonly. As she peeled the nightie off and her s sprang free, I briefly had a side view so clear that I could make out her nipple, shaped perfectly like the eraser on a brand new pencil, and her areolas and nipples were both a light shade of pink that just looked like they wanted to be licked and sucked.
