Spying Siblings

Spying Siblings By Kinkybelle It’s Friday night and I’m in my room staring at the ceiling and trying to jerk off. The reason I’m not staring at muff-diving teen hotties is because my parents took away my laptop as part of the one-week grounding I got for scoring a D on my history midterm. I mean, shit, it’s not like I failed or something. It was really more like a D+ if you think about it. And by the way, if you don’t already know, it’s nearly impossible to jerk off when you’re pissed and can’t focus on a fantasy for more than ten seconds without getting even more pissed off that you’re the only 16-year-old in America without their cell phone. I hear a girlish squeal then giggling coming from downstairs. My s****r Chrissy went to bed more than an hour ago since she has to get up for work at six in the morning, or some crazy shit like that. It had to be mom making the noise. She and Dad must still be up watching TV in the living room. I hear Mom squeal again. What the fuck is going on down there? Now I’m pissed and annoyed. And curious. I climb out of bed and quietly open my door a crack. I hear Mom’s voice, all low and flirty sounding. Then I hear Dad say something and there’s the sound of a smack. Like a skin-on-skin type of smack. Mom giggles. They’re definitely up to something. I creep out into the dark hallway with nothing but a t-shirt, pair of socks, and a hard-on. I go to the corner and peek around. The living room has one of those high, church ceilings--or whatever they’re called. The way the upstairs hallway is, it goes across past the living room, but up high, like a balcony almost. So there’s this half-wall thing there, and you can look down and see most of the living room. From where I’m standing I can see Mom’s feet at the end of the couch, and they’re kicking around some, and one of her slippers is off. She laughs, and there’s another slap. I got see what’s happening. On my hands and knees, I crawl along behind the low wall, then carefully look over. Down in the living room I can now see Dad sitting at the far end of the couch in a t-shirt and sweats. Mom is lying on her stomach with her head in his lap. The back of her robe is pulled up, and Dad has his hand tucked inside her white panties, and he’s rubbing her ass. And--holy shit--by the way Mom’s head is moving, she’s obviously giving my dad a hummer! It’s pretty gross that it’s my parents, but I’ve never had a chance to see real live sex before. And it’s not like my parents themselves are gross. A couple of my friends have told me Mom is definite MILF material, and I guess Dad was supposed to be some sort of stud back in the day--that is, if you believe what Mom says. Since they’re the ones who took away my internet, then fuck it, it’s only fair that they provide the entertainment my cock and I so desperately need at the moment. I grab my stiff dick and silently begin stroking. Dad slides his hand out and spanks Mom’s ass cheek. She wiggles her butt and her head never stops bobbing up and down in his lap. Dad grabs the waistband of the big cotton panties she has on and tugs them up, turning them into a thong. Holy crap! I can practically see my mom’s whole ass. This is getting good. I stroke a little faster. He squeezes her butt cheeks some more then stands up, pulls off his shirt, and drops his sweat pants. I can see his boner sticking out, and even from way up here it looks huge. While he’s getting naked, Mom pulls off her robe, so all she has on now are the panties that are still yanked up the crack of her ass. Dad sits back down, and Mom is all over his junk right away. I never imagined my mom sucking a cock before. But there she is, going at it like a regular pro. There’s a faint noise and I look over to my left, then freeze. Chrissy is standing there in her pajamas with her mouth hanging open like she’s about to scream. I put my finger to my lips, praying I can shush her before she makes any noise. It’s bad enough that I just got busted by my big s****r with my dick in my hand, but if I get caught by my parents I’ll never see my laptop again until I go away to college. Chrissy’s face goes from shock to disgust, but she doesn’t make any noise. I point down to the living room, and she looks. Her eyes go wide as soon as she sees what’s going on down there. I’m surprised, but relieved, when she ducks down behind the half-wall the same as me. I can tell that she’s trying to figure out what she should do. My s****r is generally a royal pain in my ass. She’s only a year older, but she acts like she has all this authority over me. Like she thinks she’s my second mother or something. She’s always ratting me out, and telling me what to do, and shit. I bet she’s trying to figure out how bad she’s going to blackmail me over this. She crawls over to where I am. There’s no point in trying to hide my hard-on since she’s already seen me whacking it. She gets right up close to my ear, and whispers. “What are you doing?” I put my mouth up to her ear. “What the fuck does it look like?” “That’s so sick. You’re a total perv.” “No shit.” She looks down at the head of my dick poking out of my fist and shakes her head. “Is Mom really giving Dad a blowjob right now?” I nod. She looks at me and she’s got this weird look in her eyes I never seen before. Next thing I know she rises up enough to peek down into the living room. I wait, but she doesn’t come back down, so I go up, too. Dad has his hand reached down and he’s fingering Mom between the legs from behind over her panties. It looks like she’s still sucking away, then she stops. “My turn,” is what I think I hear her saying, and Dad gives her another friendly spank. She starts moving to turn around, and both me and Chrissy duck down. I’m about to whisper something to my s****r, but she puts her finger to her own lips to shush me. What the fuck is she up to? After a few seconds, she goes back up for a look. When she does, I notice that her hand ends up right around her crotch and she gives it a quick rub. No fucking way. Is she really doing this? I don’t waste time trying to sort it out, I want to see what I’m missing. Mom is now facing the other way on the couch, lying on her back. I can see her tits and everything! She runs her hands up and starts playing with her nipples. This is too good to be true. I don’t care if my s****r is right next to me and I start stroking myself again. She notices and looks down at my hand working my cock. I detect a slight, disapproving shake of her head, but after a few seconds I notice her stick her hand down the front of her pajamas. s*s is into this just as much as me! Down below, Dad pulls off Mom’s panties. I would have guessed she had a full-on old-lady bush, but from here it looks like it’s trimmed into a neat little landing strip. Mom has it going on! She is still tweaking her nipples, and she spreads her legs open like a total slut. “What was it you wanted again?” my dad says with a cocky smile. “You know what I want,” Mom answers. They are talking pretty quiet, but I can just make out what they’re saying. “Remind me.” “Stop fooling around and lick my pussy.” Holy shit! I never heard my mom say ‘pussy’ like that before. “Yes, Ma’am.” Dad gets his face right down between her legs and starts eating her pussy just like she told him. And if that wasn’t enough, I get another shock when I hear a soft sigh from my s****r as soon as she sees her dad going down on her mom right there for us to see. Chrissy says something under her breath. I can almost make it out. I lean a little closer and our arms touch. She shoves me away with her shoulder, but before she does I hear, “That’s it Daddy, suck her pussy good.” This just kept getting better. Mom is holding Dad’s head now and grinding her pussy on his face. His head is moving up and down, then side to side. He’s really working mom’s twat like nobody’s business. Chrissy is moving around next to me and I look over to see what she’s up to. She pulls her pajama bottoms down partway and she doesn’t have anything on underneath. I can’t see any of her puss, but as soon as she gets her hand back down there I can hear the wet noises it makes when she fingers it. Freaking awesome. What I can see is her ass. I honestly never paid much attention to her before, but now that I see the perfect curve of her smooth butt I can’t believe I’ve had something this sexy right under my nose for years and never realized it. As I’m checking her out, her bottoms fall the rest of the way down, and she quickly kicks them aside toward her bedroom. She notices me eyeing her goodies and shoves me again, and silently mouths “Stop it,” then nods toward our parents. I turn my attention back to the living room and Mom has her feet up in the air. She’s panting and pushing Dad’s head into her pussy with both hands. How the hell is he able to breathe like that? Mom lifts her head and looks down and watches her pussy getting sucked. Something about that sends a nice tingle up my back. Seeing Mom acting all horny and slutty is totally changing the way I’ve always thought about her. “Make her cum,” Chrissy mutters under her breath. “Make Mommy cum in your mouth.” I can’t believe my normally super-bitch of a big s****r is totally perving out right next to me. I never even pictured her touching herself, and now she’s masturbating along with me like a complete hornball. I reach over and touch her naked ass. She twists away and gives me a dirty look meant to say ‘don’t do that again.’ I wait a few seconds, then do it again. She grabs my arm, digging her nails painfully into the inside of my wrist and f***efully moves my hand away. It fucking hurts like hell, but it was worth it to get a feel of that sweet butt of hers. I’m thinking the third try might be a charm, but then I see Mom thrashing around on the sofa like crazy. “Mom’s going to cum,” Chrissy whispers with a little moan behind it. “Mom’s really about to cum on Dad’s face.” Her hand is moving crazy fast between her legs, and from the look on her face, she’s about to make herself cum along with Mom. I look down and see Mom turn her head and press her face into a pillow. She arches her back, jamming her pussy against Dad’s face, and screams into the pillow. I probably wouldn’t have heard it if I was in my room with the door closed, but I can definitely hear it now. And it puts me over. I start shooting cum everywhere. Most of it splats onto the low wall in front of me and the rest spills out of my dick and down onto the carpet. “You’re so gross,” Chrissy breathes, but she keeps looking at my load of jizz dribbling down the wall and after a couple of seconds her body starts jerking and her eyes go all goofy. My s****r is making herself cum right in front of me. Fucking-A, yes! She shudders and shakes some more. When she opens her eyes she sees me staring at her with my dick in my hand. Chrissy looks more embarrassed than I’ve ever seen her before, and I’m loving it! She acts like she’s going to run back to her room, but then we hear Mom giggling. “Oh, that was good, now give me some cock,” she says without even trying to be quiet. Dad straightens up and waggles his dong at her. “Is this what you want?” “Yes!” Mom reaches for it, but he pulls back to tease her. “Stop fucking around, and fuck me!” Chrissy makes a kind of soft whimpering noise. “Look how big Dad’s thing is.” “No shit,” I whisper back. “And Mom has some nice tits on her.” “What do you want me to do with this?” Dad says, still taunting Mom with his big thing. “I want it in here.” Mom reaches down between her legs, and even though I can’t see it, I can tell she’s spreading her pussy open. “I want your fucking cock in my cunt, now!” Dad looks down at Mom’s open pussy for a few seconds, then sticks it in her. I can’t even begin to grasp how completely off the hook it is to hear my own mother say ‘cunt.’ “Holy crap,” Chrissy gasps, “they’re totally fucking right now.” Instead of leaving, she stays right where she is. Her hand finds its way back down between her legs and she starts diddling herself again. I’m still hard as a rock, so I go ahead and start stroking myself, too. My legs are getting tired from being in this sort of half crouch, but I don’t give a shit about that. Mom’s tits bounce up and down as Dad pounds into her. He’s pulling out slow, then pushing in real fast and hard. Mom seems to be liking it. She’s got her legs wrapped up around his back, and is making little grunting noises each time he slams all the way in. “That must feel so good,” Chrissy said in a hush. “To have Dad’s big cock inside you like that.” I can’t believe she’s actually saying this stuff, but I don’t want her to stop. This is too friggin’ hot! “Mom’s pussy must feel pretty good, too,” I add. “Don’t be sick, you little perv.” Dad picks up the pace and is now banging Mom good. I don’t know how he’s holding out--I would have shot my wad in about ten seconds if I had my dick in that pussy. Mom’s tits are really jiggling like crazy and it looks better than any porno I’ve ever seen. I notice that my s****r is squeezing her own boobs through her pajama top. She sees me looking and just rolls her eyes. Next thing I know she reaches up under her top and starts playing with her nipples. Sweet. Of course, I’m still jacking away, looking back and forth between my parents humping like a****ls down below, and my s****r crouching next to me, naked from the waist down, and molesting herself like a sex-starved freak. I figure with both her hands occupied, I can take another chance. I reach over and put my hand on Chrissy’s butt again. She wiggles, like she’s trying to shake me off, but that’s all she does. I rub her smooth cheek and she lets me get away with it. “Look how hard he’s fucking Mom,” she whispers, sounding like she wishes it was her. “She’s going to cum again. Mom’s going to cum all over Dad’s huge cock.” I take a big risk and slide my hand lower. I feel her clench her ass tight, trying to block me from going further, but I do anyway. I can feel the heat of her pussy even before my fingers get there. My stomach is in free-fall. I keep pushing and I feel something wet. “Noooo…” Chrissy groans through clenched teeth, but at the same time she relaxes and pushes down against my hand. I feel around, find her hole, and stick my middle finger up inside of her. She doesn’t say a word and just keeps working her clitty even faster. I can hear Mom making noises like she’s about to have another orgasm, but I’m too distracted by having my finger up my s****r’s pussy to care. I can feel the muscles inside flexing and squeezing. Now that I’m in there, I don’t exactly know what to do, so I start moving my finger in and out like I’m fucking her. She moves along with it, so I’m guessing she likes it. I hear Mom’s muffled scream again, and at just about the same time Chrissy’s pussy clamps tight around my finger and she cums, too. My s****r just fucking came on my finger! How cool is that? She massages her clit a little more and lets me slide my finger around inside for a few more seconds, then she pulls my hand away. She shakes her head, more to herself than at me. It seems like she can’t believe she just let me do that. “Turn over,” we hear Dad say from downstairs. “I want to cum on your ass.” He pulls his long cock out of Mom’s pussy, and she turns around. She has one knee on the couch, and the other foot on the floor, and she offers herself up to my dad. He grabs her hips, holding her swaying ass steady, and slips his dick into Mom’s pussy from behind. Mom reaches around with both hands and spreads her ass cheeks. Dad looks down at her totally exposed asshole and smiles. “That is so freaking sexy,” Chrissy comments quietly, then looks over at my cock. “Can you cum again?” “Yeah.” “Go ahead, then.” I start whacking off once again. She watches me, lightly rubbing her puss as she does. “You like that?” Mom asks kind of loud, and we both look back down there. “Is that what you want? You want to cum on my asshole?” My s****r was right, this is mad sexy! I feel her hand brush across my butt. My heart does a little flip, and I don’t risk looking over so I don’t jinx it. I feel it again, firmer this time, and she runs her fingers down my butt to the back of my thigh, then up. Then up some more until the back of her hand touches my dangling ball sack. I swallow hard, my heart beating as fast as my hand, and pray she doesn’t stop. Her hand turns up and she palms my nuts. This is pure heaven. Her fingers wrap around my balls and she gently fondles me as I jack off to the sight of my Dad doing my slutty Mom doggy-style. I can feel Chrissy’s body close to mine and it’s obvious she’s fingering her pussy again with her other hand. Dad spanks Mom’s ass hard, and Mom lets out a happy little squeal. Dad starts humping real fast then pulls out. He jacks his cock a few times, and unloads a massive load directly onto Mom’s wide open asshole. That does the trick for me. My body tightens up and I can feel myself about to go off. Then Chrissy gives me yet another shock. Just as I’m about to shoot, my s****r ducks her head down and takes the end of my dick in her mouth. There’s nothing I can do but cum in her mouth. She squeezes my balls and I pump my jizz straight down her throat. She gives me a couple more sucks to make sure she gets it all, then sits down on the floor with her back against the wall. Her legs are spread wide, and it’s really too dark to see everything, but I can see enough. She lifts up her top with her free hand and looks at me. She doesn’t have to say a word--I know exactly what she wants. I squat down and take one of her pale nipples into my mouth and start sucking it hard. I take the chance to feel up her other boob while I’m at it. Even though it’s my own s****r’s tits, this is better than I ever imagined. I could hear Mom and Dad talking and laughing down below, but I’m too busy with Chrissy’s boobs to care what they’re doing. Even if I hear them coming up the stairs right now I don’t think I would stop. Chrissy shoves two fingers of one hand into her pussy while the other races back and forth across her clit. Her mouth is locked in a kind of silent scream, and I just keep on sucking away at her nipple like there’s no tomorrow. It isn’t long before she gets all clenched up and has her third orgasm of the night. She keeps going at it though, and I think she gives herself one more right on top of the last one. Chrissy goes limp, but I still don’t let up. As soon as she gets her senses back, she shoves me away from her titty and pulls her top down, looking at me like I’m the one doing something wrong. I go up into a crouch and check to see what’s going on downstairs. Mom and Dad are still naked, but they’re cuddled up under one of the fleece throw blankets watching TV. When I look down at Chrissy, she’s gone. I see her crawling away, her naked ass pointed straight at me and looking all kinds of delicious. I watch her until she gets to the end of the low wall and she stands up. She gives me a serious look and puts her finger to her lips. I know that she means more than just ‘be quiet.’ She means ‘don’t say anything about this…ever!’ She blows me a kiss, bends over, picks up her pajama bottoms, and sneaks back into her room. I almost go after her, but instead I take off my t-shirt and wipe my jizz off the wall, then I crawl back to my own room. I spend the next hour smelling my fingers and jerking off while the memory is still fresh in my mind. I wake up in the morning and spank it twice more. Other than a warning look from Chrissy at breakfast the next morning, we don’t talk about what happened. Mom and Dad have no clue that their own k**s watched them fucking like porn stars, and masturbated to the whole thing. I’m definitely going to try to catch them at it again, and even if I don’t, maybe I’ll get lucky and my s****r will catch me spying again. Chrissy is a little nicer to me since I know her secret about what a horny perv she is. Overall though, she’s still pretty much a royal bitch Which is why I don’t feel bad that right now I’m in my room, staring at the ceiling, and jerking off while sniffing a pair of her dirty panties.
