Let me tell you a little about my family before I go on. My name’s Sam, I’m the second oldest of four at seventeen years old. I’m about 5’7”, a little on the skinny side, but toned from being very active, with dark brown hair which I keep buzzed very short, and brown eyes to match. My mom is a 2 nd grade teacher, and she has just recently crossed into her 40’s, but with a beautiful round face, long blonde hair, incredible green eyes, and a tight little 5’3” frame, she looks closer to 30. My dad 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, and they are both genuinely great, loving parents. I have two sisters close to me in age, Amy and Kim, both of whom epitomize the girl next door.
Amy just turned twenty, 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 couldn’t be more than a hundred pounds, standing only 5’4” and with only enough fat on her body to keep her bones from showing. In the past couple years, her chest has blown up from an A cup to a 34C, and on her tiny body, they look enormous. Her firm round ass looks quite large as well, being stuck between a tiny waist and skinny pair of sexy, smooth thighs.
On the other hand, Kim took after my father in most ways. She’s sixteen, the same height as Amy and already with a similar build, but with a little more meat on her bones. Her ass is even rounder and her hips a little thicker, still with a tiny waist and very toned thighs from being on the soccer team and running recreationally year-round. Her breasts are already about the same size as Amy’s, too, maybe a little smaller, but the two girls are so close in size that they share almost all of their clothes, though we all know in a few years Kim will probably be taller than her older sister and bustier, too. 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 practically 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 in 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 molested her sister’s body hungrily, 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 covered 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 a little short of seven inches long, but I felt so hard and the head was so swollen that I’m sure it would’ve measured 7” 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 lit room, so I continued to watch my sisters go at it passionately 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 a video of one of the most erotic sights I have ever seen. 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. And as she had peeled the nightie off and her breasts 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. Their bodies separated just a moment while Kim removed her top and Amy slipped off her shorts. I hardly had time to admire Kim’s body before they were wrapped together in the same position as before, but it only took a second for me to see that Kim’s body was nearly as sexy as Amy’s.
With her arms and legs around Amy’s body again, Kim latched her lips onto her left nipple and vigorously worked it with her lips and tongue, while she wrapped her fingers and palm around Amy’s other breast, squeezing it lightly while her thumb played with her hard nipple. Then I saw the tips of a couple fingers from Kim’s other hand appear between Amy’s thighs and as they moved into my view more, I could see that they were rubbing Amy’s hairless wet crotch roughly on either side of her slit, which was opening more and more as her sister continued to touch her down there.
Her fingers moved slowly up and down, teasing Amy relentlessly for a couple minutes before finally Amy was begging for it. “Fucking hell, Kim, just fuck me already. Fuck my pussy with your fingers, please!” And Kim obliged, suddenly pushing two fingers between our sister’s bald outer lips and straight into her pussy, causing a hard groan from her. They slid in as deep as they could with little resistance and Kim left her two digits buried inside Amy for a moment, but I’d guess she was moving her fingers around just right based on the guttural sounds escaping Amy in that moment.
“Like that, baby?” Kim asked, as she switched her mouth’s attention to her sister’s other breast, kissing it softly all over as she looked up into Amy’s eyes. Amy’s breathing got harder as Kim started fingering her wet cunt slowly and deliberately.
“Yess, ohmygod, right there, keep doing that.” Kim must’ve found the g-spot, and I could see her fingers moving in a smaller margin now so that she would hit it over and over. “Ohh baby, Kim you are so fucking good. I fucking love the way you fuck me.” But I don’t think Kim was paying hardly any attention to what her sister was saying. After all, she was playing with Amy’s breasts with her mouth while her fingers tirelessly massaged her older sister’s g-spot. Her thumb found Amy’s clit and began rubbing it madly. This sent Amy over the edge, and suddenly her whole body tensed and her orgasm overtook her.
Kim recognized this, raised her head from Amy’s chest, and with her hand on the back of Amy’s head, pulled their faces together for a really hot kiss. I figured this was to keep Amy’s moans from echoing throughout the house, since even after they were muffled by Kim’s mouth, I could still hear her cries of pleasure vividly. The younger girl’s fingers never stopped working the other’s pussy, and though at the beginning of her orgasm, Amy had been pushing her hips down begging for more, after a couple minutes of the overwhelming sensation, she was desperately trying to get off of her sister’s fingers. But Kim still had her legs around her waist and her hand on the back of her head, and neither grip was budging. After a moment, Amy’s struggling stopped when another orgasm hit her and she was again bucking her hips wildly against the teen girl’s hand. Mid-orgasm, Kim rolled them over so that Amy was on her back and Kim was now straddling her at the waist, but their passionate kiss continued and so did her hand’s busy work.
Finally, their movements slowed, until their lips were kissing softly and Kim’s fingers were again just lightly caressing her sister’s pussy, which was covered in her cum now, as were her thighs, the area of her bed spread beneath her and, of course, Kim’s hand. “I think it’s my turn now, sis,” Kim said as the kiss finally broke and they looked tenderly into each other’s eyes.
“Mmm, I want to eat your pussy. Stay just like that, let me scoot down,” Amy instructed, putting her hands on Kim’s firm, round ass and lifting her a few inches so that she could slide down between her sister’s thighs until her face was right beneath her dripping snatch. She guided Kim down until her pelvis was less than a couple inches from touching her nose, then she used her thumbs to pull those puffy wet lips all the way open. She raised her head off the bed with her tongue just barely poking out from between her lips and placed a soft kiss on her pussy, slipping her tongue out a little more and licking her sister’s sweet opening. That, paired with her nose brushing the tip of Kim’s exposed clit, queued a raunchy moan from the teen. Kim’s hands cupped her own breasts firmly, occasionally pinching her nipples.
Amy slowly lowered her head back until it was resting on the bed, and Kim’s hips naturally lowered at the same speed so that the light teasing her sister was administering wasn’t interrupted for a second. After another minute or so, I could see that Kim was getting a little frustrated and was starting to gyrate her hips on her older sister’s face, begging for more. Amy giggled and kept teasing her sister’s pussy with her tongue.
Kim couldn’t take it anymore and grabbed a handful of her sister’s hair and forcefully positioned it so that her lips were right on top of her hard little clit. Amy relented and opened her lips just enough to take her nub between them, sucking on it and rolling her tongue against the tip of it. One of her hands went up to fondle Kim’s unoccupied breast, since Kim still had her hand tangled in Amy’s blonde locks. Amy’s fingers skillfully toyed with Kim’s nipple, rubbing it firmly with two fingers, then squeezing and pinching it. Meanwhile, her other hand snaked around Kim’s hips to her ass, which was smacked playfully a few times before that hand dropped to the bottom of that beautiful ass. Amy slipped her fingers right between Kim’s thighs and quickly found her tight, wet pussy, and her middle finger slid all the way in with no hesitation. She withdrew it all the way, and then pushed it back in along with her ring finger. Kim couldn’t hold back from letting out an extra hard moan and as Amy started to fuck her hot, slippery cunt with those two digits, Kim started moving her hips up and down to match the rhythm.
“Oh my god, my pussy is on fire right now.” She said between moans as she hunched over and squeezed both her breasts firmly, having finally let go of Amy’s hair. Kim started sucking harder on her clit and pumped her fingers in and out as fast as she could. “Oh god, I’m so close, Amy, fuck, yes, I wanna cum all over you, keep going.” My younger sister did tend to swear a lot, but I had no idea her mouth was this filthy, and same with Amy. But it was definitely one of the best discoveries of my life.
Spurred on by Kim’s dirty talk, Amy went all out. I could see her lips really working her clit, and every few seconds she would part her lips so that her tongue could really whip across it. But when she added a third finger without breaking rhythm, Kim was almost instantly hit with an intense orgasm. She was moaning almost nonstop, and it looked like every muscle in her body tightened up, and the only movement she made was when her hips involuntarily thrust down on her sister’s mouth every few seconds. Amy took it in stride though, with her three fingers pushed as deep into her little sister’s convulsing pussy as they would go and with cum rolling down her hand and arm, and her lips still wrapped around Kim’s now-ultrasensitive clit. As the waves of her orgasm gradually weakened, Kim looked down into her big sister’s eyes just as her talented lips finally released the hard little nub. Kim’s moaning had stopped, but she was still breathing heavily and her body twitched with after tremors for a couple minutes to follow. Amy moved her face more directly under Kim’s pussy and finally withdrew her fingers from it, allowing her backed up juices to spill out onto her pretty face, and it was quite a load. It fell primarily on her nose and mouth, which was opened and happy to receive Kim’s sweet pussy nectar.
“Mmm, your cum is the tastiest I’ve ever had, sis,” Amy said as Kim fell onto her back beside her sister, completely worn out from the mind blowing orgasm she had just received. Amy scooped as much cum into her mouth as she could, and when she was done she sucked her fingers clean.
“Well, I’ve only ever tasted yours and mine, but I do think yours is better,” Kim said while she idly toyed with her clit and turned to look at her beautiful older sister. “I love you, sis.” Amy returned her gaze, and then they both leaned in for a soft, loving kiss which lasted only a few seconds. Their mouths separated, but just barely, and it looked as though they had both nodded off with their lips less than an inch apart and their noses gently touching.
