Incest/Taboo Evolution

I'm not sure exactly what I had been expecting to walk in on, Ben thinks. I guess I just assumed Dad would be on top of Mom or something, or maybe doing her from behind. I hadn't given it much thought really, I was too preoccupied with my own excitement knowing I was going to get a blowjob from Mom, even if she was getting pummeled by Dad at the same time.

I certainly hadn't expected anyone else to be in the room. Our elderly next door neighbor, Doctor Moran, comes over to use Mom sometimes, but I think his late night visits are pretty rare.

When I open the door, I notice both bedside lights are on, which gives the room a nice warm feeling. It's more than enough light to see what's happening. The initial shock passes before any of them even notice I'm standing in the doorway, and that's when I start to decipher the jigsaw of bodies on the bed.

Dad is kneeling back on his own heels on the mattress with his back to the headboard. His hands are holding a woman's thighs steady as he slowly fucks her. I can see it's Mom he's fucking, but only because her white blonde hair is unmistakable as it sticks out from underneath the very sexy ass sitting on her face, grinding herself on Mom's mouth. Some of Mom's long hair is hanging down over the end of the bed.

Dad has his head tilted and is kissing the woman who is having her pussy eaten by Mom. It's when they break their kiss and the woman on top leans back, keeping her hands on Dad's shoulders for balance, that I see my sister's face. Her eyes are closed and she throws her hair back as she enjoys what seems to be a good tonguing she's getting from our mother.

"Mmmm Mom, I'm cumming," she breathes, and grinds herself down hard on our poor mother's beautiful face.

I don't know why I'm surprised really. I mean, I was on my way in here to blow my load into Mom's mouth. Of course Dad has been screwing my sister Claire. She's a sexy little bitch. I've wanted to nail her too, I just haven't had the balls to do it.

Dad sees me first, and gives me a knowing smile. He doesn't seem to mind I'm gatecrashing his threesome.

"Shit, Ben!" Claire squeals, seeming genuinely shocked to see me. She tries to cover her tits to keep her modesty, but she doesn't get off Mom's face I notice. She's not that fucking embarrassed for her to cut her pleasure short. Claire's turned into a little flirt recently, those outfits she's been wearing when she comes running with me and Dad, her yoga pants stuck up her ass. And the short skirts around the house, I should have known something was going on. How could Dad ignore that hot little piece of ass right under his nose.

I'm not sure if Mom even knows I'm here yet, Claire has her thighs right up against her ears. But whatever Mom is doing seems to be having the desired effect.

"Fffffuuck Mom, yes, right there, oh Jesus fuck that's good," Claire moans out, as her whole body trembles.

My sister then moves forward towards Dad, dragging her mound off Mom's mouth and down past her chin. She wraps her arms around Dad's neck and pulls him in for a deep kiss, as he keeps slow fucking Mom.

I can just see Mom's forehead and eyes now that Claire's ass has moved out of the way a bit, and that's when she sees me. She smiles, I can only see her eyes, but I know she's smiling at me.

"You need me Ben?" Mom says, sounding a little muffled, as she uses both hands to Claire's ass to gently push her a little further off her chin. My sister shuffles down another couple of inches, her ass now hovering over Mom's neck. I came into the room completely naked, and Mom's eyes drop to my throbbing cock as she watches the huge drop of precum that's dangling from the tip. "Let me take care of that for you honey."

Mom reaches out her hand towards me, and I instinctively start walking closer to her, my bobbing cock leading the way. I walk my cock right into her waiting hand, and her soft slender fingers wrap around my shaft.

"Hmmmm, you do need your Mommy tonight, don't you baby," she says then moans quietly, as she squeezes my cock and gives it a couple of gentle strokes. She can feel how hard I am. I don't think I've ever been this hard in my life. This tangle of bodies is probably the hottest thing I've ever seen, and now I'm about to get a blowjob from my own gorgeous mother, whose mouth is probably full of my sexy little slut sister's pussy juice. "Bring that thing around here," she says, pulling me by the cock closer to the end of the bed.

Mom then uses her feet to push herself down the last couple of inches to the end, bringing Claire and Dad with her. Dad's still slowly thrusting his enormous cock in and out of Mom, while he makes out with Claire at the same time. I can't help but look at my little sister's perfect ass just below Mom's face.

When I move around to the end of Mom and Dad's bed, the back of Mom's neck is resting on the edge of the mattress. Her head is hanging back slightly.

I look up and I see Dad staring directly at me. Claire is bending down now and has her head near Dad's crotch, right where our parents are joined together. I can't see what she's doing though, but as she has bent further down now, it's caused her pussy to sit right on Mom's neck.

Mom has released her grip on my cock so I can move closer to her mouth, into the position I want to be in. Without using my hands, I drop my cockhead to Mom's lips.

She sees me looking at my sister's ass and smiles up at me. Teasing me, she places a hand on each of Claire's ass cheeks and pulls them apart, revealing my sister's little puckered hole to me. Then she opens her mouth wide, leaving no doubt what she want me to do.

Placing a hand on each side of her face, my thumbs under her jaw as her head is now almost upside down, I slide my cock into my mother's warm, wet mouth. Her tongue goes to work straight away, swirling circles around my tip.

Then I do what I've wanted to do all day. I press my hips forward and push my full length down Mom's throat. I knew she would take it easily, she's the best cocksucker I've ever had.

I slowly start fucking her throat in this perfect position, my balls coming to rest on her nose every time I shove it in. I take it out after a minute so she can catch her breath, then I stick it back in.

When I push my pole down her throat again, I notice her neck bulging up firmly against Claire's mound. And then I see it. Claire is grinding her clit down on Mom's neck bulge each time I thrust forward. What a fucking whore. When I let my eyes roam up along my sister's naked back to her head, I see she is taking Dad's cock into her mouth. I look down at her magnificent ass again, just there in front of me, the temptation is too much. I take my hands off Mom's face and place them on my sister's ass instead, and I hear her groan with Dad's cock in her mouth when I do this.

I must have been mesmerized by all this for too long, as Mom taps the back of my thigh with her hand to tell me to pull out so she can take a breath.

She gasps and inhales deeply this time, then as I'm about to stick it back into her mouth again, she stops me. I can't see her face as it's between my legs, underneath my cock and balls, but she reaches her hand up and grabs my shaft. What she does next happens so fast, but I can't deny I wasn't already thinking about it. Mom lifts my cock upwards away from her mouth and pulls me forward the few inches past her face to Claire's soaking wet slit. She lifts it up another little bit, and then leaves it down on my sister's ass.

I've wanted to fuck Claire so much recently, there is no way I'm going to pass up this opportunity. I grab my cock in my right hand, and position the tip at the entrance to her bald pussy, then without any hesitation I push it inside. She's a tight little bitch, and the loud moan tells me she likes what I'm doing. Judging by what I walked in on tonight, I would imagine Dad has already had his monster cock up Claire's cunt many times already, so she will be able to take me no problem. When I push it all in and she doesn't protest even when I bottom out, I think my suspicions are correct.

I relish in the pleasure of being inside my little sister, so I just stay still while I massage her ass and legs for a minute. I need to hold off cumming too if I'm honest, the excitement of having sex with Claire is a little overwhelming. And her pussy feels so fucking good wrapped tight around my cock.

That initial sensation passes, and I'm about to pull back to start fucking her when I feel Mom's mouth sucking on my balls. She's taking them into her mouth one at a time. They're probably too big for her to fit both in together.

Eventually I can't hold back any longer, so I pull my cock out to the tip then thrust it back into my sister, over and over, building up speed each time. Claire looks back over her shoulder at me, and there is pure feral lust in her eyes. I always suspected she was a little slut, that nerdy bookworm persona of hers was just a cover up.

"Fuck me Ben, fuck me. I've always wanted this," she says, and I can see she's jerking off Dad at the same time. Then she faces forward and leans down, taking him back into her mouth again.

I'm getting close, Claire's tight cunt feels amazing. When I feel my climax rapidly approaching, I pull out of my sister, and shove my cock back into Mom's waiting mouth. I came here for Mom's mouth, and that's exactly where I want to be when I cum.

I don't bother warning her, I just push it all the way until my balls are squashed against her nose. When I feel her throat muscles contract around my shaft it tips me over the edge. I unload straight down Mom's throat, while holding onto Claire's hips as I empty myself completely into my mother's stomach. It's such an intense orgasm, I end up collapsing on top of Claire's back.

After a few seconds, Mom gives me the warning tap again, and I pull my cock out while still lying on top of my sister, and Mom underneath her. I can feel my slippery cock rub all over Mom's gorgeous face. She can't move from the position she's in, but she just lies there and takes it.

When I catch my breath, I stand up and take a step back. I look down at Mom and see what a fucking mess she is. Her face is completely covered in cum and spit from the throating she gave me, she is almost unrecognizable. Her mascara is streaking onto her cheeks and forehead, and her sexy hair is a total mess, matted with saliva.

But she still smiles up at me. "Did you like that baby?" she asks.

"Yes Mom, you are amazing," I say back.

She then manages to squeeze her way from under Claire, and says "I'm just going to freshen up, be back in a sec," then quickly leaves the room, leaving me there with Dad and Claire, who is still sucking him off.

"You enjoy that?" Dad asks, and I can't figure out if he's pissed off with me or not.

"Yeah, she's so hot. Nobody blows me like her," I say, deciding to just be honest.

"She's a fucking pro, isn't she," he says, smiling. "You need to try your sister too, she's like a vacuum cleaner."

I've started to recover already, and my cock is rising again ready for more action. That's when Mom comes back into the room having cleaned off the mess I made on her face. She's completely naked, and my eyes are popping out of my head as I try to see as much of her as I can.

"Sit down over here," Mom says to me, motioning to a chair close to the bed. I do what she asks without even thinking.

As soon as I sit down, Mom comes close and throws one leg over me, then lowers herself down onto my rigid cock, taking me straight into her pussy. No easing it in, she drops down to my root in a split second, and immediately starts riding me. She gave me no time to think, but immediately I know this is everything I've ever wanted. She is definitely used to taking big cocks. I suppose, she is married to Dad!

"Aaaahh fuck, that's what I need," she says. "I've wanted this baby, I need my son's big cock."

It's all happened so quickly, but this is everything I've ever wanted. I'm fucking my own mother, the reality is starting to sink in and I can't believe it. Any doubts I've had about this evaporated the second Mom mounted me, her pussy feels like it was made for me. Then she leans down and kisses me on the lips, opening her mouth and sticking her tongue searching for mine.

My stunning mother is fucking and making out with me. It's my wildest dreams come true. I can feel her pussy clench around my cock and a flood of juice spews out of her around my balls. She breaks our kiss but keeps her face close to mine, then I feel her tongue lick me all over my face.

She leans her upper body back then, giving me a perfect view of her great tits as they bounce up and down while she rides me. I squeeze them with both hands, pinching her nipples, and then I clamp my mouth around one of them sucking it deep into my mouth. God she has amazing tits. It's all getting too much for me and I feel my balls twinge.

"I'm cumming Mom," I whisper.

"Mmmmm, yes baby. Inside me. Inside Mommy," and she cums herself again.

I erupt into my mother as she shudders in my arms. No orgasm I've ever had comes even close to matching this.

"You stay in Claire's room tonight Tom, I want Ben in here with me," Mom says to Dad when we eventually recover. She's still sitting on top of me on the chair.

"Sure thing honey," Dad says. "Go easy on him," he says then with a laugh.

"I think he's more than able for me," Mom says.

Dad stands up, his massive cock sticking straight out in front of him.

"Come on Claire, let's leave the love birds to it," he says to my sister as he takes her hand and helps her stand up too. When she does I get to see her fully naked form properly. She's such a sexy little thing. I'm going to fuck her senseless soon. But tonight is all about Mom.

That night with Mom was the best night of my life. When Dad and Claire left, we climbed into bed naked and actually fell asleep, but only for an hour or so. I woke up with Mom's hand holding my soft cock. Seeing her naked body asleep beside me quickly caused my erection to grow in her hand. I woke her while mounting her again, and I fucked her slowly on her back, to begin with. But of course it ended up in another pounding fuck session.

We fucked in every position imaginable that night, and I really seen what a cock hungry slut Mom is. She's a wild animal in bed, and fucks harder than I imagines possible. I can usually go all night, but Mom is the first woman to truly wear me out, and we eventually fall into a deep sleep in each others arms in the early hours.

The sun shining through the window wakes us up the next morning, and we realize we're both filthy from all the dried up cum and sweat.

"I can't believe last night happened Mom," I say. I'm being genuinely honest, it doesn't feel real.

Mom smiles at me, her head resting on my bicep facing me. "Oh it happened alright," she says, and closes her eyes as if she is remembering it all.

"I know it's wrong Mom. I mean, what you and me did. And what I did with Claire," I say, a little panicky.

"It was wrong Ben, in the past it would never has happened. But we don't live in the past anymore, and the world is different now. We can't help it baby. We just can't keep these urges at bay anymore. So just go with it," she says, and I can see she's thought this through.

"Maybe. Maybe you're right. It just scares me a little, in the cold light of day, that's all," I say, but I do feel a little calmer.

The room is a complete mess too. The bed was even moved a few feet sideways towards the window. The memory of having Mom bent over the side as I rammed her pussy while standing on the floor behind her comes back to me.

"Come on, let's take a shower," Mom says, as she drags me out of the bed towards the en suite.

The temptation is too much for me to ignore this beautiful naked woman in the shower, and I don't even pretend washing is my priority. I enjoy every inch of her perfect body while the water from the huge shower head sprays down on both of us.

I turn Mom around and stand in close behind her, my rock hard cock sticking into her thigh gap, between her toned legs. I'm enjoying soaping her magnificent tits from behind, squeezing them and pinching her nipples. She just smiles, letting me explore her body as much as I want.

I can't help it when I start grinding myself up against her ass, she just feels so good. Then when I bring one hand up and take hold of her neck from behind, I think she realizes what's coming.

She places her hands on the tiled wall, and arches her back a little presenting her ass hole for me to do as I please. What a woman.

I reach down with my free hand and guide my hard cock to her ass, slowly pushing the tip inside. There's resistance, but not too much. I push forward and she meets me by pushing back, taking my full length into her ass in seconds. She's used to taking cock up there too it seems.

"Hmmm," Mom groans. "Just like your father, he likes shoving his cock up my ass in the shower too."

I finish off in a matter of minutes, shooting my load deep into Mom's rectum. Then both of us finally wash ourselves properly and dry off.

When we come downstairs together, Dad and Claire are already up. They're having breakfast at the kitchen island, and Dad is reading the news on his tablet. It's almost 9am on Saturday morning, and there's a really relaxed atmosphere in the house. It's like all the sexual tension has been released and we're left in a satisfied, contented state.

I'm a small bit worried about how Dad is going to be. I mean, I did spend the night with his wife. But I need not have been concerned.

"Hey Ben, you fancy going for a run? I don't know about you, but I need to get some fresh air. No better way to blow off the cobwebs than getting outside on a nice sunny morning like today," he says enthusiastically.

"That's a great idea Dad," I say, "I'd love to. What about you little sis?"

"Nah, I'm a bit tired. I didn't get much sleep last night," she says, and gives Dad a flirty look.

I'll bet you didn't, I think to myself. I check her out while she's making another coffee, and I feel my prick stir immediately. I know I stuck my cock into her last night, but we didn't get to fuck properly. I really hope she wants to have a repeat of that, only for a lot longer next time.

Both Dad and I get changed, and I meet him out front in five minutes. Then we stretch a little before heading off together.

"8km sound good?" Dad says as we turn onto the sidewalk at the end of our drive.

"Perfect Dad, but better take it nice and slow. I'm a little tired myself," I say.

"I'll bet you are," Dad says, and chuckles knowingly to himself.

The run with Ben was the perfect way to start the day, in more ways than one. The fresh morning air was exactly what both of us needed after the nights we just had. But even more important was the chat we had along the route. Any lingering misgivings quickly evaporated, and I made it clear to Ben that I'm OK with what he and his mother have now. I may not be ecstatic about it, but I'm changing and willing to adapt.

As for him screwing his sister, sure it's wrong, but looking at them turned me on quite a bit. And she's my daughter, so I can't really be a hypocrite either considering what I'm doing with her.

When we return home, I can see in through the kitchen window Laura and Claire sitting on the sofa talking. We kick off our dirty running shoes before we go inside, and I fill two glasses of water, downing mine in seconds before refilling.

Ben and I are still catching our breaths when Laura and Claire stand up and come over to us.

"So, Claire and I have been talking, about, everything," Laura starts off saying.

"Oh," I reply, raising an eyebrow pretending to look worried.

"We talked about last night. Well not just last night, we talked about everything that's been going on," Laura continues.

"Sounds.....interesting?" I say, skeptical.

"No, it's all good," Laura says. "Claire was really honest with me, and it helped me process a lot of stuff too. Things have really changed around here, I think you'll both agree, and we haven't really discussed anything, properly."

Ben and I look at each other, not really sure where this is going, or even what to say.

"It can be a little, awkward is probably the best word, to, eh, initiate something with each other, especially when our urges for each other can be so intense," Laura continues on. "I mean, we are all family after all, and we haven't had this sort of relationship until now."

"You mean, it's a bit weird to use my daughter when the mood takes me," I say with a grin. "I think I understand what you're saying dear."

"Exactly Tom, it can feel a little strange," Laura says, agreeing with me. "We're family, and I know we have developed certain desires for each other, but it's still not really a normal everyday thing to just start into it with each other. And that's what Claire and I want to get out in the open now. We want it just as much as you two, trust me! So that's why we've decided to try something new around the house."

"OK, this does sound interesting," I say, starting to relax a little now.

"We know you guys can get as much sex as you want as soon as you walk out the door. But something tells me it's what's inside this house that appeals to you more," my wife says, and a dirty little smile appears on her face. "It certainly appeals to Claire and me, that's for sure. So we want you both to know, you can use us whenever you want, anytime day or night, no need to ask for permission, we're giving that now."

I'm not really sure what I'm hearing, and I look at Claire to see her reaction. She catches my eye and smiles when I raise my eyebrow.

"That goes for me too, day or night," Claire says, a little more shyly than her mother, but I know she means it.

"You both can take us whenever you need some relief. I know the urges men get can be really strong, so Claire and I are here for you both," Laura goes on to say.

Ben's jaw is practically on the floor. Here is his beautiful mother and sister giving themselves to him on a plate, he must be struggling to keep the excitement from showing. I know I am!

"To make things easier for everyone, Claire and I have decided to make a little change. This is Claire's idea by the way, but I love it," Laura says, building the suspense. "We're going to dress, differently, around the house from now on. We're going to wear things that you both will probably like, and that will give you nice quick access to the.....areas.....you need to get at, if you know what I mean."

I'm getting hard just hearing this.

"If either of us are on our period, or just not feeling particularly horny, we will cover up a little more, and you'll have an idea what's going on and stay away, that way we can all avoid any awkwardness," Laura says.

"The other one of us can take the load, so to speak," Claire says then, which I have to admit is pretty funny.

We all just look around at each other until Ben eventually breaks the silence.

"Fuck yes," he says loudly as he high fives me, unable to hide his delight.

"OK, calm down Ben," I say, trying to keep my composure, but inside I'm just as excited. Two beautiful women on tap, whenever we want them. Claire, available to me 24/7. Is this a dream?

"Claire and I are going to go to the mall to get some new.....suitable clothes," Laura says.

"So plenty of short shirts you mean," I say, unable up hide the big wide grin on my face.

"Well, yes actually. Very clever Tom, you catch on quick," my wife says sarcastically, but with a warm smile. "We're going to the mall right now actually."

"Would you like Dad and I to come and help you pick out some new things?" Ben says.

"We know what you horny bastards like, I think we'll manage just fine on our own," says Laura.

"Nice try, perv," Claire says to her brother, and then both of them start laughing.

"Worth a try son," I say to Ben. "But I think we'll be more than happy with whatever they wear."

I was so happy after talking with Mom about Dad and Ben, and the changes that have been happening recently, Claire thinks.

I've been so turned on all the time lately, it's nice to know I'm not the only woman feeling like this. We talked a lot about what's been going on with me and Dad, and she really put my mind at ease about the whole thing. She thinks that some things that weren't acceptable before, like fucking your parents I suppose, are becoming more normal in the world we live in now, so I don't feel like such a freak anymore.

Mom admitted that she gets strong urges when Ben is around her, so it's nice not being the only filthy bitch in the house. I really opened up to Mom. I told her everything.

I've really started to enjoy when men want to use me. I get plenty of older men especially looking for sex with me, Dad's age and some a lot older. And I can't lie, it makes me soak my underwear. It feels so dirty when they pull my panties to the side and roughly shove their old cocks up my twat, then squirt their cum into me after only five or six humps. Some of them say thanks afterwards, and others just give me a little slap on the ass when they're done with me. None of them have had a cock even close to Ben's, and definitely not Dad's. But I don't care, it's knowing the effect I have on the old fuckers that gets me off.

I've fancied Ben for as long as I can remember, so when he stuck his cock into me last night, I nearly came on Mom's tits there and then. He's such a stud, I can't wait to have sex with him again, and now that he knows he can whenever he wants, I hope he fucks my brains out every day.

But it's Daddy that really makes me weak at the knees. That battering ram between his legs splits me in two, and now that he knows I'm able to take it, he sure doesn't hold back on me.

It makes me so wet just thinking about Dad and Ben using me when they want. I have so many fantasies. I want them to take me from behind without any warning. Or throw me onto my back and spread my legs, then pin me down and ride me with their full weight taking my breath away as they lay on top of me.

I want them to come into my bed in the middle of the night and mount me like a bitch in heat. When they need sex, I want to be there for them to relieve themselves in, to be their sex toy to use however they like.

I want to be my Daddy's whore, my brother's little cum dump sister. It's all I can think about, and it feels so good to finally admit it to myself.

Tom switches off his laptop and pushes his swivel chair back from his desk as he stands up. It's Friday evening, and Tom realizes he has coasted through the week at work. But in his defense, it's been a mind blowing week at home. He can't believe it was only last Saturday that Laura and Claire made themselves fully available in the house for him and Ben to use. And use them they certainly did.

"Do you want a quick suck before you leave?" Jean asks me as I pick up my laptop bag.

"Oh Jean, that sounds nice. You always know exactly what I need," I say, and then go over to her desk unzipping as I walk.

While Jean works her magic mouth on my cock, I think back to last Saturday, the first day of our new "arrangements" at home.

Laura and Claire arrived back from the mall weighed down with shopping bags. I think they knew Ben and I were eager to see a sample of what they bought, as both of them went upstairs to change as soon as they got home. We've seen both women completely naked of course, but there is just something exciting about a gorgeous woman dressing up in sexy, provocative clothes. Knowing the real purpose in this case doubles the excitement.

Claire came down first, dressed in the shortest little black skirt I've ever seen. It didn't even fully cover her ass, with the bottom of her cheeks on show. On top she wore a black lace see through string top, no bra, so her tits were clearly visible and looked ravishing. Her top left her midriff and lower back bare, and her toned stomach catching my eye almost as much as her sexy legs and ass. She made me hard in seconds.

When I looked over at Ben, I could see his cock tenting his loose shorts. He hesitated, but I didn't. I'm sure he won't mind waiting for his mother.

Claire walked past me towards the sofa and was about to sit down. I walked up behind her, pulling my cock out on the way, and put my hand on my daughter's shoulder, stopping her before she reached the seat. Using my left hand, I eased my prick in between her legs from behind, feeling her soft ass on top of my shaft as I searched for her wet hole. She wasn't wearing any underwear and she didn't say anything, or even look back at me, but she did take a small step to the side with her right foot, opening up her legs and her pussy to let me in.

I found her slit and pushed my tip in, bringing a gasp from my beautiful daughter. She was excited, and her slippery pussy felt so good as I slipped my big cock further into her. Claire bent forward and placed her hands on the armrest of the sofa. I didn't even need to pull her tiny skirt up out of the way.

I only lasted a couple of minutes before pushing her down further onto the armrest, and pressing most of my weight down on top of her ass and back, as I grunted and shot my big load into her. When I pulled out and stepped back, Claire stayed lying on her stomach.

Laura still hadn't come down at this stage, I was pretty quick I guess. Ben obviously couldn't wait any longer. As soon as I stepped back, he moved in behind his sister taking my place. He already had his throbbing cock out, and he didn't waste even a second before he buried himself to the balls into her already sloppy, cum filled pussy. He fucked her hard and fast, and dumped a second load into Claire in a matter of minutes.
