Incest/Taboo Evolution

Ben returned home just as Carla and I were walking down the stairs after our shower together. Carla has dressed in her blue and white summer dress again, and was still fixing her white bra straps back into place over her shoulder as we came into the kitchen.

I have just spent the last 30 minutes screwing my son Ben's 19 year old girlfriend in the shower. It's not the first time I've fucked her, that was last Monday in the gym. But she was just a stranger then, when I had no idea she was dating Ben.

To my credit, I thought she was at least 25, maybe that was due to the dim lighting in the gym. When I discovered yesterday that she was just 19, I was in shock. I have never had anyone that young since our world changed 3 years ago.

At first I was mad at myself, a bit grossed out even. I mean, I have a 19 year old son, and an 18 year old daughter. The idea of fucking someone the same age as them, didn't really appeal to me. But let's just say I've come around to the idea, especially now that I've tested Carla out again knowing her age.

Carla and I go our separate ways in the house now. Carla goes and sits down on the sofa with Ben to watch some TV and chat. I grab some coffee and breakfast in the kitchen. Laura joins me shortly after, and I ask her if she would like one too. She does, so we sit down on our high stools together. I'm a bit apprehensive about Laura's reaction to what happened with Carla. I've never had sex with anyone else in the house before apart from her. She has though, many, many times. Not with her son's girlfriend, but still....

There is silence between us for a minute or two, but then Laura starts talking about the usual things we chat about every day, like what we will have for dinner that evening, news about our neighbors, general stuff like that. Everything is back to normal, as if nothing happened.

"It's almost 1pm," Laura says. "Jean and Pete will be here soon. I better make a start on lunch."

"I almost forgot they were coming over," I say. I didn't almost forget anything.

"Hey Ben, will you and Carla be staying around for lunch? Dad's work friend Jean and her husband are coming over at 2," Laura raises her voice so Ben will hear her.

"No thanks Mom, I'm going to drop Carla home soon, so I might hang out there for a little while. But I'll be back later. I can say "Hi" to them then if they are still here," Ben answers.

"Have you seen Claire today?" I ask.

"No, I haven't actually. She must be studying in her room again," says Laura.

"I better go check on her, see does she want something to eat," I say.

I knock on Claire's bedroom door, and wait for her to answer.

"Come in," she says a few seconds later.

"Hey Claire, just checking you're OK?" I say as I open the door.

"I'm fine Dad. Just getting some work done for the test tomorrow," she says.

"We're having lunch at 2pm when Jean and Pete get here. Will you take a break from your studies and join us outside then?" I ask.

"Yep, sounds nice Dad. Count me in," she says.

"Perfect, I'll let your Mom know. See ya then," I say as I close the door behind me.

I walk back to the living room and notice Ben and Carla have left.

Jean and Pete arrive at 1.50pm. I've worked with Jean for the past 11 years. She's 51, and her husband Pete is a little older at 54.

"Hi guys, thanks for coming over," I say when I open the front door before they knock, holding a hand out for Pete to shake, which he takes.

Then I give Jean a hug and a kiss on the cheek, as Laura stands behind me in the hallway.

"Hey Jean," Laura says, and gives her a hug. "Hi Pete, great to see you again," she says then, giving him a hug too.

"Laura, you look amazing. I love your outfit," Jean says to my wife.

Laura is wearing a pair of white knit short shorts, and I mean really short short. On top she has a pale blue spaghetti strap top, that just about covers her tits. She looks amazingly hot. Laura is dressed like this on purpose of course. She is showing Jean what she has to compete with, and is laying down a marker. Pete will have to sit down soon I would imagine. His eyes are glued to Laura, and I'm sure he is struggling to hide his erection already.

Jean obviously knew the game plan for today, and she came dressed to impress too. She is wearing a short and form fitting cream colored casual dress. It's sleeveless, with a nice plunge down the front. It's made from a light stretchy material that clings so tight to her body, it leaves very little to the imagination. The way it sticks to her little pot belly is unbelievably sexy. It shows how confident she is in her body, and is turning a part of her that other women might try to hide into another asset. Her tanned legs are on show as usual, with her snug fitting dress coming to just above mid-thigh.

I'm so accustomed to Jean in her business-like clothes she wears to work, what she is wearing today is rare for me to see. I like it. If she intended to make an impression on me, it's working. But I suspect it's more for Laura, Jean knows I would screw her in a bin liner. Jean is intimidatingly hot. You just know by looking at her that she could chew you up and spit you out. And you would love every second of it.

Laura leads Jean and Pete out to the back yard and they all sit around the outdoor table. I get the drinks after asking everyone what they want. There's a lot of small talk about how nice the weather is, what the kids are doing, shit like that. I've relaxed a little bit, as Laura seems to be very at ease with Jean. They're getting on really well, and it doesn't seem to be an act, by either woman.

I don't have a lot in common with Pete. He doesn't have any interest in football, and is pretty reserved in general. But he's a good guy, and opens up a little when you make the effort to find some common ground. However, what Jean sees in him I do not know. Jean is the ultra milf, a teenager's wet dream. Pete is a scrawny, socially awkward nerd. But everyone to their own.

After about 20 minutes of chatting, Laura suggests we all go inside for lunch, as she has that table laid out already. I get fresh drinks for everyone, a glass of white wine for Jean and Laura, and a red for Pete. I'm still on the sodas. Laura is making the last few preparations for lunch, doing something with a salad, and then takes a cooking dish out of the oven.

"Jesus Tom, I completely forgot, do you want to dump your load in me?" Jean suddenly says to me. "I know you like to first thing in the morning. Have you relieved yourself already today?"

There is silence in the room. Jean is standing at the end of the island in the kitchen, the top of which is an inch or two above her waist. As she says this, she leans her elbows on the counter top, and looks back at me. I'm standing there with my mouth open, momentarily speechless.

I've never had sex with anyone in front of Laura. This morning with Carla, Laura didn't see us, she only heard what we were doing.

Also, this is Jean. JEAN, who I know Laura is seriously jealous of, and who she suspects I'm having some sort of affair with. With actual feelings involved!

"Eh, yeah I have already, thanks anyway Jean," I panic mumble in response.

I glance over at Laura, who is just staring at Jean. If looks could kill.

Pete is standing there like an imbecile, swirling the wine around in his glass.

This is a serious power play by Jean. By asking me if I want to use her is basically accusing Laura of not taking care of my needs. Also, the confidence Jean has to offer herself to me, with my wife no more than ten feet away looking on and listening, is extremely arousing.

But my decision to take Carla has set a new atmosphere in the house, and Laura seems to have accepted this show of strength. Now that I've had a few seconds to compose myself, I think it's time to drive this new dynamic home.

"Actually Jean, that was hours ago. I think I need to relieve myself again," I say.

She hasn't moved from her slightly bent over position. I leave down my soda, and casually walk the four or five steps to the end of the kitchen island, squeezing my growing erection with my hand as I walk. Laura has stopped what she's doing, holding a salad bowl and some plates in her hands, seemingly frozen. Pete is still swirling his wine, the dimwit.

I get to the end of the island where Jean is, and stand behind her admiring the shape of her ass in her tight dress. Before I touch her, I unbutton and unzip my shorts, but leave them around my waist. Then I pull my semi hard cock out, leave it hanging there, and watch it rise to full stiffness. Laura and Pete are watching it too, but Jean is just looking out the window seemingly disinterested, while casually taking the odd sip of wine.

Then, like I do most mornings when I get to the office, I take the bottom of Jean's dress in my hands and slide it up her legs. The material in her dress today is so light and stretchy it slips up over her ass and hips without any effort. She isn't wearing any panties. What a whore. But really, why would I have expected her to wear them, she likes to make sure I have easy access. She knew I wouldn't refuse using her today.

Part of me is waiting for Laura to say something. But she keeps quiet. The whole situation is arousing me so much, I feel like I could soon cum all over Jean by just standing here.

I don't wait any longer. I step forward and take hold of Jean by the waist, and without even needing to guide my cock into her hole, I push it in the whole way with one shove. She's cumming on me already, I can feel it, but she's trying to suppress it, trying to keep up the disinterested facade.

I withdraw almost fully, leaving the tip barely inside, then slowly penetrate her again. I do this five times, not speeding up, then on the sixth plunge I empty by balls into her with a gush, letting out one single, quiet grunt.

My cum splashing into Jean gives her another orgasm. She doesn't suppress this one as she slaps her hand down hard on the counter top, and hisses "Ffffuck".

I feel like I've stepped out of my body and am looking down on this situation. Me with my cock stuck in my boss, who is bent over the island in my kitchen with her dress pulled up, and her husband and my wife looking on.

"Laura, clean this up," I say to my wife, nodding down to my cock as I pull it out of Jean.

WHAT! What the fuck have I done! Did I just say that out loud to my wife. In her own kitchen. I'm either very stupid, or very brave. I've been thinking over what Emma said on Friday night, about Laura being kinkier than I realize. I want to really test that theory, but this was so spontaneous, I said it without even thinking. I'm terrified how she will react.

Even Pete is shocked, he's stopped swirling his wine around the glass.

Jean is still bent over the island, white cum dripping from her snatch. She's not even trying to hide the smirk on her face.

Laura doesn't move. Neither do I. I've moved my left hand up onto Jean's lower back, leaning slightly on her, and turned my hips to the side with my still hard prick pointing towards my wife. A string of thick white cum hangs from the tip. My left hip is resting against Jean's ass.

"Laura," I repeat, but before I say another word, she leaves the salad bowl and plates down on the table. Then she hesitantly walks over to us.

Pete is looking Laura up and down as she walks over, his eyes boring through her shorts. He's left his wine glass down.

She stops just short of Jean and me, maybe deciding what to do next. I'm starting to have doubts about humiliating my wife like this. My beautiful, perfect wife. When suddenly she drops to her knees, and leans forward with her mouth open.

She slurps up the ever lengthening strand of cum hanging from the head of my cock with her tongue, and swallows. Then she licks along my full length, from base to tip, several times, eventually covering it all.

Finally, she opens her mouth wide and slides my cock down her throat, tightens her lips at the base, and slowly draws her head back revealing a clean cock inch by inch.

"Now her," I say.

Laura, still kneeling, narrows her eyes at me. But she does what she's told. She is already close enough to Jean's pussy that she doesn't need to move, she just turns her head to the right and a leaking hole is right there, two inches away.

My wife sticks her tongue out again, and presses it against Jean's clit, slurping up the cum that has seeped out and is hanging there.

Jean lets out a long moan, reacting to Laura's soft tongue. She is still leaning over the counter top, and Laura is positioned behind her, so she doesn't have the view I have.

Laura then slides her tongue up a little, to Jean's fuck hole, and clamps her mouth fully around her pussy. She sucks my load directly out of Jean, swallowing every drop of that too. I'm rock hard again looking at this.

When Laura pulls her mouth away, I immediately turn back to Jean, and shove my cock back up her cunt again.

Laura doesn't move, she just stays kneeling, her head inches away from where Jean and I are joined.

I screw Jean hard, then when I can feel my climax brewing, I pull out and slide it into Laura's mouth. She had it open waiting for me.

Three hard thrusts and I unload again, into my wife's throat this time.

Laura isn't humiliated, she accepted this as a challenge. She's proving to me, and Jean, that nobody can compete with her for me. There is no low she won't sink to.

The next few minutes are a little awkward, but Pete, of all people, comes to the rescue and restarts the conversation by complementing the wine, and asks me where I got it. He's not a bad guy.

By the time we sit down for lunch, everything has returned back to normal.

Claire has joined us and is talking to Jean and Pete about college, where she wants to go and things like that. She eats her lunch, and hangs around for 15 or 20 minutes afterwards to be polite, then she disappears back to her room.

Pete is sitting at the kitchen table about to start eating lunch when Tom and Laura's daughter Claire comes into the room. He hoped she would join them, as he had been looking forward to seeing her since Friday, when Jean told him they were invited over.

He met Tom's wife on several occasions at Jean's work functions, and seeing her was always a pleasure. She was a stunning woman. Jean spoke about Tom and his family regularly, so he knew they had a 19 year old son, but more interestingly, an 18 year old daughter. Who by all accounts was a younger version of her mother. Now who wouldn't want to see that!

Claire sat down in the free chair beside him at the table, as he hoped would happen. Watching her walk over to the table wearing a little white tank top and short denim skirt had him drooling. Her skin was flawless. Not only did she look like Laura, in his opinion she was even better. She was truly beautiful.

I can't take my eyes off her, Pete thought to himself, but surely she won't notice a few subtle sneaky peeks of her body while she sits beside him.

It had been a very strange afternoon so far. Jean offered to let Tom use her a little while ago. That in itself wasn't particularly interesting or unusual, Jean allowed men use her all the time, whether I was around or not. Often, these men would come to their house, use her, and then leave immediately afterwards.

However, there was a strange atmosphere between Tom and his wife today. He used Jean of course, I think he does that quite a bit at work, so nothing untoward there. But I'm not so sure how Laura felt about him doing it in her presence today.

Which leads me to the most peculiar thing that happened. After ejaculating into Jean, Tom demanded that his wife clean both of them up. Very strange. But compelling to watch all the same. Laura looked ravishing, I must say. And she certainly knows how to please a man from what I could see.

Claire goes back to her room after a delicious lunch, ready for an evening of study. She's nervous about the exam tomorrow, so she wants to cover as much of her reading material as possible today.

She looks up when she hears a gentle knock on her door. It's probably Dad checking if I'm OK. He worries a lot about me, she thinks.

"Come in," she says.

"Sorry, I hope I'm not disturbing your studies," says a voice, as the door opens slowly.

That's not Dad. It's Pete, Dad's work colleague's husband.

"Oh, hi," Claire says to him.

"I was just looking for the bathroom," he says, "sorry for intruding."

This obviously isn't the bathroom, but he comes into the room anyway, and closes the door behind him.

"So what are you studying," he says, trying to make conversation.

"Biology, I have an important exam tomorrow. So I should be getting back to it." she says.

"Wow, biology right. Sounds tough," Pete says, trying to keep talking to her.

Claire hasn't time for this drawn out chit chat. This guy is here to fuck her. He had been gawking at her legs the whole time she sat beside him at lunch. He's just too shy or awkward or whatever to cut to the chase.

"What way do you want me?" she says.

"What, eh, eh, what, what do you mean. I-I-I don't know what you're talking ab....," he stammers out.

"Look, I know why you're in my room. You know why you're in my room. So, what way to you want me?" she asks him again.

"On your back," he says quietly. "Thanks."

Since Claire turned 18 a few months ago, she has had her fair share of men of all ages try to screw her. She tried to hold out to begin with, but her urges became just too intense.

She needed it on such a basic, instinctive, maybe even primal level, that when she gave in to her nature, the sense of relief and joy that came with sex was overwhelming and empowering.

Now she quite enjoyed the thrill of sex. The only problem was, none of the guys she's had sex with have been able to satisfy her. She has never had an orgasm from a man, and certainly not from a penis. Granted, she's a relative newcomer to the world of sex, but she hasn't even gotten close.

She relies on her trusty vibrator for that.

Claire is sitting at her desk with her laptop open beside a notebook and pen. She stands up, and reaching up under her blue denim skirt with both hands, she pulls her light pick panties down. She lets them fall to the floor, then steps out of them, kicking her converse sneakers off too.

Her denim skirt is short enough that she can leave it as it is, he should be able to get at what he wants when she lays down on her back.

She then sits onto the bed, and puts her head back on her pillow. She lifts her feet onto the bed, bends her knees and places both feet flat, while spreading her legs wide.

Her bald pussy is there waiting for him, but he's just standing there looking. He's pretty old, so maybe he can't get it up?

Then he moves at last. He kneels on the bed, and lowers his face down between her legs, up her skirt. He started licking the full length of her slit, several times, then sticks his tongue up her pussy as far as he can reach.

Finally, he moves up to her clit and starts lapping with his tongue. Now this was a lot better. But he must have been ready at this stage as he didn't stay there for long. Still, she enjoyed those few seconds.

He seems really hurried now, and is scrambling to undo his pants to get his cock out. He manages it pretty quickly, as he mumbled to himself, "Goddamn it....so tasty....little...pussy....fuck....so young...," were the words she managed to catch.

When he starts climbing up her body, mauling her legs and tits on the way, she knew by his eagerness that he was just going to shove it into her.

And that's exactly what he did. But she didn't mind, he had her pussy nice and wet after slobbering all over it.

He humped her for about a minute, then bucked hard.

"Oh my.... oh my.... oh my.....," he whispered with his eyes closed.

I felt a small hot squirt inside, and that was it. He looked kind of embarrassed afterwards, and even apologized, for whatever reason. Then he said thanks and left my room. I notice him pick up panties and stuff them in his pocket really quickly before he left, he didn't think I saw him.

Oh well, at least I can get back to my exam revision quicker than I expected.

About 30 minutes after lunch, the four of us move over to the sofa with our drinks. Laura and Jean really do seem to get on well. There isn't a single moment of awkward silence now, as they chat about every topic under the sun.

Pete asks if he can use the bathroom, so I tell him where it is and off he goes.

It's after 5pm now, and Jean says it's time they were leaving. Pete has been gone for a while now, and I can see Jean is getting impatient. He returns a few minutes later, and Jean stands up to leave.

We say our goodbyes, give the hugs, Jean tells me she will see me in the office tomorrow morning, and they leave.

"That was lovely," Laura says. "We should have them over again soon."

I can breathe properly again, at last.

Claire went back to her room after lunch, but Pete simply couldn't let the opportunity to see more of her pass.

So I decided to visit her room for a.......private chat, thinks Pete, under the pretense of using the bathroom. She is a very forthright young lady, and she seemed eager to "get down to business" as they say.

What a sight she was, lying on her bed with her legs open, inviting me to enjoy her. I don't think I have ever seen such a vision of perfection before. Her legs were a particular favorite of mine, as was her very tasty, and as it turned out, very very tight private area.

I tried my best to give this young lady as much pleasure from the encounter as I was getting, but unfortunately the excitement got the better of me too soon.

I must see more of the lovely Claire again before long. Tom may not be happy with me for having my way with his daughter, but he's not really in a position to argue, he seems to be very much in love with my wife.

I also took a little souvenir, I really hope Claire doesn't mind.

Laura steps into the steaming hot bath that evening with an unexpected feeling of fulfillment coursing through her. Jean and her husband left an hour ago, then she and Tom spent until now cleaning up after the late lunch. Now she needed to unwind.

What a day it had been. It started off with Tom not being able to control himself with Carla, their son Ben's girlfriend.

She heard everything from the bedroom, then the arrogance shown by her husband was shocking, and something she had never seen from him before.

But that insult paled in comparison to what happened this afternoon.

She had been looking forward to taking Jean down a peg or two for months, that's why she had Tom invite them over. The bitch was getting a little too comfortable with Tom over the last year, and she needed to reclaim her turf.

She had planned on giving both Tom and Pete the fuck of their lives, and rubbing that slut's nose in it. But that's not how things worked out.

Instead, Jean had the audacity to offer herself to Tom before she had the chance to put her plan into action, in her own house. Initially, she thought there was no way Tom would use Jean, he had never been with anyone else in front of her before.

She certainly had other men while Tom was present, many men. She always knew men wanted her. Men of all ages have lusted after her all her life. But the last three years since everything changed have been on a different level, because now these men knew they could have her.

She enjoyed being used by men. It made her feel sexy and powerful, and being honest, she liked Tom knowing other men wanted her, and could have her, and she liked him watching. She knew he would get jealous, and that made her even more horny.

But Tom wouldn't do that to her, or so she thought. She knew it was double standards, but she couldn't help it.

However, there was something different about Tom this weekend, he had changed. He was always a good husband, and he was always able to satisfy her sexually. Her taking other men in front of him was satisfying a different need. But physically, very few men, if any, could compete with his cock.

Now the tables had been turned. Not only did he use Jean, he humiliated and degraded her by making her clean up the mess, on both him and his slut.

Laura would never admit this, but she loved it. Every second of it. What Tom made her do was one of the peak sexual experiences of her entire life.

She wasn't expecting that to happen. Recalling it now makes her feel embarrassed, and a little ashamed. But she remembers how she felt at the time, in the moment, and it was exhilarating.

Now as she lay in the bath, she had a sense of fulfillment she never experienced before. She knew she wanted to be treated like this again. Degraded. Humiliated. She wanted more.

Ben didn't get home in time for lunch after all. When he eventually got back at 8pm, he asked me if I wanted to go for a run. I was keen to get an extra session in, so we got changed quickly, I shouted up to Laura in the bath telling her where we were going, and then we hit the road.

After some small talk, Ben gets to what he had been building up to say.

"So Dad, I know about what happened, she told me," he says when we are a couple of miles into the run.

"OK," I say back.

"I just wanted to say, I get it. It's OK," he says quietly.

"That's good," I say. "You're a good kid Ben."

Then after a couple of minutes silence, I ask, "When will Carla be coming over again?"

"We're going on a date tomorrow night. But you will see her around at ours a lot I'm guessing," he says.

We ran in silence for a long while after that brief exchange. I don't know what happened or was said between them, but one thing is clear. Ben understands he will be sharing Carla with me from now on.

The alarm on my phone wakes me at 5am. I have a stop to make on my way to work, and I'm not sure how long it will take.

I drive right up to Emma's front door. I check my watch as I put the key in and turn the handle. It's 5.20am.

I been thinking about what I'm going to do now all weekend. When I open their bedroom door, I can hear Emma and Jack snoring lightly, both fast asleep, as I hoped.

I reach down and switch on the bedside light on Emma's side. I've already removed all my clothes, and the anticipation has me fully hard.

Emma opens her eyes, but Jack continues snoring. He's a heavy sleeper, but he won't sleep through this.

It only takes Emma a second to understand what's going on, and I can see fear in her eyes, but also a hint of excitement hiding there too.

I gesture for her to move into the center of the bed, making room for me on the outside. As she makes room, I lift up the thin blanket and slip into bed beside her.

When I'm in, I twist her hips, making her turn her ass towards me, and face her husband. As I do this I notice that she pulls down her cotton pajama shorts and panties, and kicks them off her feet. Yeah, she's up for this alright.

I'm so excited to be in this position with Emma. I've wanted her for so long this feels like a dream. I don't waste another second. With both of us lying on our sides, I slide my cock in between her legs from behind, searching for her pussy without using my hands for guidance. I'm busy squeezing and mauling her breasts, that I have admired and longed to touch for decades. I'm pushing my cock but getting resistance, so I adjust my position down a little lower, and that does it.

My cock slides into her loose, well worn pussy. And it's heavenly. She can take my massive girth with ease. I bottom out on the first thrust, and her pussy juices are slopping around my cock making a lot of noise. I lift her left leg up, holding it up by the knee.

"Wha, what's going on?" Jack grumbles, still half asleep. "Tom, is that you? What the hell is going on?" he asks again, starting to wake up now.

"Just fancied fucking Emma. I've wanted to for years, just never got around to it," I say to him, while not being able to hide my resentment.

I pull down the blanket, showing her husband what we're doing.

"Are you fucking kidding me?" he starts to shout.

I don't even slow down.

"I know about you and Laura, you sneaky piece of shit," I say back, cutting him off. "You can't have your cake and eat it. Now you know how it feels."

"I'm not looking at this shit," Jack says, pulling off the blanket that was covering him, but he doesn't leave.

He is too engrossed in staring at my cock entering his wife to move. That does it for me, triggering my climax, which I shoot deep into Emma.

Emma hasn't cum, but she speaks for the first time saying thoughtfully, but purposefully to insult Jack, "So that's what a real cock feels like."

There is a look of heartbreak and hurt on Jack's face. He knows he'll never be able to satisfy his wife again.

I think about carrying on fucking Emma, I sure as shit want to. I want to make her climax on me, I want to make her happy. But I want her to want me, and I know exactly how to do that. I'll leave her wanting more.

So I pull my still rock hard cock out of her, give it a quick wipe in their blanket to clean off, and jump out of bed. I grab my clothes and leave the room, leaving the married couple behind looking at each other, my cum flowing slowing out of my wife's sister.

I check the time on my phone as I close Emma's front door behind me. 6.30am I think I'll hit the gym.​
