Incest/Taboo Evolution

Claire waited until she heard the shower running in her dad's en suite before she went down the hallway to his room. She hadn't showered yet, instead she quickly stripped off her running clothes, and dressed in loose shorts and t-shirt. The door to his room was open so she could see he had left the bedroom and gone into the shower.

I can't wait to see what he does with these, she thought to herself as she copied what her dad did with her pink panties, and left the thong under his pillow. Before she left the room, she couldn't help herself, she had to sneak a peak of her dad in the shower.

The door was open a crack, barely even an inch, but it was enough if she got close enough. She walked over quietly and leaned forward bringing her eye as close to the door as possible, her forehead against the door frame.

He was standing with his back to her, with the water from the shower spraying down onto his head and upper body as he washed his hair. He looked good from behind, she thought. But that's not what she wanted to see. She was starting to get nervous, she needed to get out of here before she got caught. She had just taken her head away from the door when he turned to his left to get more soap. Claire banged her head against the frame she was so eager to get a look. Fuck, I hope he didn't hear that thud.

Holy shit, he's hard, and it's even bigger than I remember, Claire thought. I wonder why he's hard, is it because of me? I hope it is, oh fuck that's making me wet.

Dad was really starting to get into shape, Claire noticed. He's looking good. But that dick, wow. Mom is such a lucky bitch, and Carla! And whoever else he screws with it. I wonder would he fit inside me, it's so thick. Jesus Claire, what are you doing, he's your father. Playing a little game with your underwear is one thing, but actually doing that is something very different.

Seeing Dad's cock again made Claire even more excited about leaving her used underwear for him. She had never been this wet in her life.

OK, I need to get out of here, I better not push my luck too much, he's starting to go soft now anyway. It's still massive hanging down between his legs.

I quietly leave his room and run into the main bathroom for a quick shower.

I'm frozen on the spot, holding the black thong in my hand. When I brought the flimsy piece of material to my nose a few seconds ago, my cock reacted with a force I've never seen before. It went from flaccid to a throbbing baseball bat in less than ten seconds.

I have no doubt in my mind who owns them. I'm just back from a run with my 18 year old daughter Claire, and looking at the style of this piece of underwear, they are specifically designed for exercise. These are Claire's, no question. There is nobody else at home!

I bring them to my nose again, fuck they smell good. I look for the area that would have covered her pussy and inhale, yep that's the spot, the scent is strong here. I've smelled a lot of pussy in the last few years, but none come close to this. It's so fresh, it's making me almost unable to control myself. Knowing it's my daughter is definitely adding to the thrill.

I let my towel fall to the floor, and take hold of my cock with my right hand. I keep the thong held up to my face with my left, and I can feel the dampness from her sweat and pussy cream. I've only stroked myself five or six times, slowly, when I feel the familiar tingle, I'm close to cumming already. I take the thong away from my face and look at the part of the gusset that had the strongest scent of pussy. Then I look a couple of inches down the narrow string to the area that would have been shoved between her cheeks against her asshole. I can't help myself, I bring this to my nose for a sniff too. It's fucking divine. Not a strong smell, just a mild musk. I'm a dirty bastard, I know, but I can't help it, I want to get at as much of her as I can.

When I can feel my climax about to erupt, I take the thong and hold the widest part of the material that would have covered her mound stretched out in my left hand. I aim my cockhead at the center, then another two pumps and I unload. There's too much cum for underwear this skimpy to hold, but I fill the front to the brim. The rest falls on the floor beside the bed.

After I've finished shooting my load, I leave the sodden thong down on the bed and get dressed. I hadn't thought this through, I just got caught up in the moment. I hadn't considered what this could mean.

Claire being so brazen has really upped the stakes in this little game we're playing. She must have thought after all that it was me who came into her pink panties when I got them back from Jean. She would be right of course. No way would she have left this thong under my pillow for me to find if she thought I was just the delivery boy.

Now that I've cum in Claire's underwear, again, I know exactly what I'm going to do with it.

Claire has showered and gone downstairs when I walk down the hallway to check if she's around. I quickly go into her room with her drenched thong balled up in my fist. I place it under her pillow, only this time I put it on top of her vibrator. My slimy cum is smeared all over her little toy, and some has dripped out on her pillow and the bed sheets too. But there is still a good pool of it still waiting for her in the thong.

Before I leave her room, I make sure to pull a string of the thong out from under the pillow so that she sees it there.

I feel a little bad about the mess I've made on her bed, but if my suspicions are correct, she won't be too bothered by that.

Now little lady, over to you! I bet you weren't expecting this back so quick.

I feel a lot more relaxed after relieving myself, and I'm famished now. When I get down to the kitchen, Claire is standing at the cooker preparing dinner.

"Hey Dad, dinner will be ready soon. Are you hungry?"

"Starving, I worked up a big appetite this evening," I say.

"Thanks for taking me along on your runs. I'm really getting into it," Claire says.

"Love having you come along. You keep me on my toes."

When the food is ready, both Claire and I grab a plate and sit side by side at the high counter. We eat our dinner together like this, chatting the whole time.

"OK, I need to get some study done, see you later Dad," Claire says, then gives me a hug.

When she leaves the kitchen, I tidy up and put the leftovers in the refrigerator for Ben and Laura. Then I sit and watch TV for a while until Laura gets home.

It's the first thing Claire sees when she walks into her room. The black material poking out from under her pillow. It's easy to spot on the all white bedding.

She almost dives onto the bed to grab it. When she pulls the waistband of the thong, the rest follows with her vibrator getting dragged along too. Oh he's bad! He left it there on purpose.

When she lifts the thong up off the vibrator, a string of slime hangs from the material down to the tip of the toy. I don't actually believe it, she thinks, he used my thong to shoot his load in. This is so fucking hot. Well that settles it for sure now, it must have been him who did it in the pink panties too.

Her thong is completely saturated with his cum. It was damp when she left it for him from her sweat, but now it's soaked through and heavy. She opens up the material at the front, and she is shocked to see a huge blob of cum.

She sticks her forefinger into it without thinking. It's so gooey and wet. She can't believe this came out of that gigantic cock she couldn't stop looking at earlier.

This is wrong, she can't help but think. We shouldn't be doing this, whatever it is. But it's giving her the biggest thrill of her life. It's only harmless fun, she tried to reason with herself.

Claire's mind was being pulled in opposite directions, but there was only ever going to be one winner. What started with a dirty old man taking her panties as a souvenir had turned into the sexiest game between her and her father. She didn't need to think about what she was going to do next, she would have done this with her pink panties if she could.

She grabbed the waistband of her cotton shorts and panties, and pulled them to the ground. Stepping out of them, she opened the thong with both hands, being careful not to spill the huge blob of cum sitting in the material at the front. Then lowering her arms, she stepped her right foot through the leg hole, then the left. She was in almost a squatting position. Keeping her knees slightly apart, she pulled the thong up between her legs by the thin straps, up over her hips and onto her waist. She immediately felt the cold of the cum load, she wasn't expecting that, she had only felt warm cum up to now. But it made sense, he must have shot this out over half an hour ago.

Using her hand outside the material, she pushed the blob down into her slit, massaging it around her clit, and working some into her hole. Then she grabbed the back of the thong and pulled it up tight between her ass cheeks, squeezing her father's semen back over her asshole.

She felt filthy, and she didn't even know why she did this. But she also never felt so sexy and like a woman in her life. She never felt so alive.

I need my vibrator, she thought. She lay down on the bed in her soaking wet thong, and switched on the cum covered toy, held it against her clit outside the material, and came with a shudder in less than a minute.

Claire has been on my mind a lot since the evening she left me her black thong. That was Tuesday, and I've noticed that she is wearing more revealing clothes around the house than she has ever done before. That's not helping me to stop having thoughts I should not be having about my daughter.

It's Friday evening now, and Claire, Ben and I have just got home from a run. It's the first time Claire has come running with me since Tuesday, and I can't help but wonder, maybe even hope, that she will leave her underwear for me again.

I leave the en suite door open a little wider than I normally would, and I'm paying a little more attention for any "visitors" to my room. But I don't notice anything. I can't help but feel a bit disappointed.

I grab a towel when I step out of the shower, and wrap it around my waist before walking back into the bedroom. And then I see it - something is left under my pillow again. How did she get in without me noticing?

I quickly grab what's left there, and see it's a pair of light blue high-cut panties. They've been worn, maybe earlier today, and are still a little bit damp where her slit would have been. I bring them straight to my nose and sniff in her scent. I'm fucking rock hard.

Then I notice something fell onto the bed when I lifted them up. It's a note, "Wear these to bed tonight, and fill them for me tomorrow morning. You know where to leave them."

I've never worn ladies underwear before, but immediately I'm turned on by the prospect. As soon as I read the note, I knew I would do what she wanted. Fuck, I want to wear them for me!

I towel myself dry, have another sniff of Claire's panties, then I put them on, stretching them almost to the point of ripping as I pull them over my big thighs. They're much too small for me of course, and my massive cock looks obscene in them. It's bulging out one of the leg holes, even when it's soft. The feeling of the material against my balls is amazing, and there is no stopping the erection I get from that. I manage to settle down, and my cock softens. It takes a lot of adjusting, but I get my balls and some of my cock to stay in the small little panties. I put on my normal boxer shorts over them.

I finished getting dressed and go downstairs to have dinner.

When I come down, Claire is there eating. She just looks at me, and raises an eyebrow while momentarily glancing down at my crotch, a barely noticeable movement of her eyes. I nod my head down once, less than an inch. There is nothing more than that simple communication. If either of us didn't know what the other meant, both gestures would not even have been perceptible.

I see a faint hint of a smile on her face as she eats.

Laura and I watched some TV together on Friday night before going to bed just after 11pm. I had been wearing Claire's panties all evening, and I have to admit, they felt so good. Not comfortable as such, but the feeling of them around my cock and balls, and wedged up my ass crack, was a lot more enjoyable than I ever thought it would be. It felt wrong to be wearing them, which made it even hotter.

I decided to wear them to bed too, something about sleeping in them beside my wife added to the excitement. Both of us fall asleep as soon as our heads hit the pillow. I was sleeping soundly until a noise woke me. It's 2.13am on my phone when I check it, half asleep. It takes me a minute to realize what's going on. Ben's fucking bed squeaking again. Carla must have come home with him tonight, they were still out when we went to bed. Maybe I'll take Carla for a few minutes when he's done, I think to myself. I'm getting a little hard listening to them.

It's at that point I feel Laura move in the bed beside me, the noise must have woken her up too.

"Hey honey, you're awake. I hear Ben is having some fun," she says, very voice still groggy.

She reaches over and gently feels my inflating cock through my boxers, the panties are underneath.

"Somebody is a little turned on. I don't blame you, it's making me wet listening to him screw her too," Laura says. Then she slides her hand down the waistband of my boxers. "Oh, what's this?"

When she slipped her hand down to grab my shaft, she can feel it covered in women's underwear. In truth, I wanted this to happen, and I want her to know who they belong to. I'm almost certain she's going to love how kinky this is, how naughty and wrong.

"Hmmm, very nice," she purrs, "did you get them from my drawer? Or are they from the dirty laundry basket? Even better" she quizzes me, sounding like this is turning her on big time.

"They're not yours," I say. She has her hand on my hard cock, gripping it inside the material.

"Oh you dirty old man. They Claire's? You're wearing your daughter's underwear?"

"Yes. I've been wearing them all evening," I confess, getting a little less confident in Laura being into this.

She reaches for the bedside light and flicks the switch on. Then she pushes down the bed sheets and pulls my boxers down fully.

"I need to see this," she says, kneeling up on the bed now.

It's some fucking sight, I have to admit. A middle aged man, wearing his daughter's sexy panties, with his hard 8 inch long, and grossly fat cock sticking almost fully out the left leg hole, one ball hanging out the right and the other bulging the material. No chance of the panties holding me in now I'm hard.

"You dirty old fucker," Laura says quietly. But then she grabs my pole and starts stroking it overhand. "Did you take them from the laundry basket? Are they worn?"

"She gave them to me to wear," I say, just going all in. "She wore them at school today."

Laura pulls her knees together and takes off her shorts, but leaves her own panties on. Then she lifts her t-shirt off over her head. Her tits look magnificent as usual. She pulls Claire's panties fully over to the side, allowing my cock to stand up straight, then throws her left leg over my body. She uses her hand to pull her own panties to one side too, and being careful to lower her fuck hole down onto the tip of my cock, drops down taking me in ball deep. She's dripping wet, the horny bitch loves this.

"Did....you....smell....them?" she asks between breaths. "Did.....you....smell.....her.....cunt?"

"Obviously," I say. "She smells good. Fresh. She smells better than you."

I don't mean that. I love how Laura's pussy smells and tastes, but I know this is the type of shit she loves hearing when she's in this sort of mood. Although it's never involved her daughter before, but I take a gamble on that. And it works, her pussy clenches me hard, and she rides out her climax.

"Fucking pervert. You're own daughter," she breathes, and continues to grind on me.

Then she hops up off me and takes her panties off in a hurry.

"Let me wear them, quick! You can fuck me while I'm wearing them."

She pulls them down my legs and has them pulled up over her ass in seconds. Then she gets onto all fours, her ass up the air ready for me.

"You can imagine I'm her," she says so quietly, I can barely hear.

Kneeling behind her, I pull Claire's panties over Laura's right ass cheek and plunge my cock into my wife.

"Oh Claire, you're such a dirty little bitch," I say, really getting into it.

Laura is seriously enjoying this. She is fucking back against my thrusts as hard as she can.

"Come on Daddy, use your little girl. Do you like wearing your little slut's panties," Laura says, copying Claire's younger voice.

I spank her ass hard three times, then a fourth, as I ram my pole into her as fast as I can. Then I grunt loudly and dump my load deep inside her hole.

"Oh Daddy, your cock is so big," Laura says, and I'm erupting inside her cunt.

I collapse on the bed, and Laura lies down beside me, snuggling her head up to my neck. She fixed Claire's panties over her pussy, and it's catching my load as it flows out.

"That's so hot Tom," she whispers. "She's a dirty little bitch doing this with you."

"Do you mind? Or are you freaked out?" I ask.

"It's making me hornier than I can ever remember. It's wrong, but it's so sexy."

"I've something to ask you," I say, then hesitate.

"Go on," Laura says, after waiting a few seconds for me to speak.

"Will you..... would you mind...... ehh...."

"Just get on with it Tom," she says laughing.

"Will you wear her clothes sometime?" I eventually pluck up the courage to ask. "In bed? Or maybe around the house when she's not here?" This is a real spur of the moment thing. The idea just came to me. Claire and Laura look so alike it's remarkable.

Laura leans up on one elbow, and moves her face close to mine, then kisses me deeply.

"Anything for you," she says when she breaks the kiss.

"Here, put these back on," she says then, as she slips Claire's panties down her legs and over her feet.

I pull them on again, and I feel the wetness at back of my balls where some of my load had dripped out of Laura.

"What are you going to do with them? The panties?" Laura asks me.

"Give them back to her. I'll leave them under her pillow."

"Oh, you answered that very quick. I take it this isn't the first time."

"No, just once or twice before now. She wants me to jerk off into them before I give them back," I say, full confession time. "I'll do that first thing in the morning."

Laura pauses for a few seconds before saying anything. "Little slut," she finally says, but with a smile on her face.

Claire woke up early on Saturday morning. She had an uneasy night's sleep, waking up several times during the night. She has started to become a bit obsessed with this thing she had going on with her Dad.

Mom got up a few minutes ago and went downstairs first, which meant Dad was alone in bed right now. I wonder did he wear my panties all night, she thought.

Claire had no doubt that he would do what she asked, and now was his chance. She needed to make sure he knew the coast was clear, so she got up, and rather loudly made it known she was having a shower.

She stayed over 20 minutes in the shower, that should give him enough time, she thought. When Claire walked back into her bedroom, she immediately saw her light blue panties exactly where she expected them, under her pillow on top of her vibrator.

They were absolutely destroyed in cum. These panties were much bigger than her running thong, so Dad had more material to play with. She felt so excited knowing that her Daddy had kept this big load just for her.

Without giving it a second thought, she stepped into them and pulled them up her legs. The cum wasn't cold this time, he must have just squirted it out while she was in the shower. There was such a big blob that it spread into every crack and fold, getting into her pussy and all around her asshole. The feeling of his semen now covering her most intimate places was exhilarating.

She felt dirty doing this, like a complete slut. But she can't believe how it's making her feel. She's imagining her father's big sweaty balls and enormous cock bulging the panties that she's now wearing. She pulls them higher up her hips, the material slipping into her slit.

Most of the light blue material had darkened, but the odd patch of original color was visible - exactly what she wanted.

She then went looking for something appropriate to wear, for what she had in mind. She decided on a little white cotton skirt that was so short, she always needed to be careful when bending down or reaching up for something, as her underwear would always be showing. But today, that's exactly what she wanted. She wanted to show her Dad that what she's wearing, to show him his seed is all over her.

On top she wore a light blue vest top that showed off her flat stomach. She felt very slutty wearing this outfit, and that was without even thinking about what was in her panties.

When I went downstairs, Mom and Dad were having breakfast. I need to do this quickly, she thought, before I lose the courage. Dad was sitting across the table from Mom, so I went to the cupboard behind Mom, to where I knew he could see me clearly. I opened the cupboard door, then bent forward at the waist, keeping my legs straight and a little bit apart, pretending to look for something. It's the cupboard they keep all the cleaning stuff, just my luck! Mom would know this is the last cupboard I would open intentionally!

I could feel the bottom of the skirt slip halfway up over my ass, so I knew the cum stained panties would be there for anyone to see. The way I've noticed Dad look at me recently, there is no way he could resist looking at me now in this position. He would even be able to see between my legs!

I wait there for the longest 10 seconds of my life, then stand up and fix my skirt back into place. I close the cupboard door and turn around. Dad flicks his eyes away from me, looking back down at his plate. But I saw him, and that made me add my own little bit of juice into the panties with his cum.

I need to stay sitting at the breakfast table until my "situation" settles down. I'm so hard from looking at Claire in her outfit.

Laura knows exactly why I'm not moving, and she's loving it. She's not helping either by the way. She slept naked after we fucked last night, and she didn't bother getting dressed properly before coming down for breakfast, just wrapping her robe around herself instead.

She has purposely let the front fall open, leaving her left tit on show. I can see her nipple poking out. She doesn't seem to care that Claire is about to sit down at the table beside us.

Claire sits down beside her mother, and seems to push her tits together with her arms as she moves her food around the plate. I don't know where to look, and my prick is about to burst it's so hard.

I can't take it anymore. I stand up to leave, my tented shorts poking out proudly. I'm gone beyond caring. Both women stare at my crotch as I turn away from the table, giving them a good side view.

I meet Ben and Carla walking down the stairs.

"Hey Ben," I say. Then I just take Carla by the hand and lead her back up the stairs she just walked down. We go into the master bedroom. She bends over the side of the unmade bed, and pulls down her leggings and thong just far enough. Her sexy 19 year old ass is mouth-watering.

Carla takes my breath away every time I see her, she is so painfully beautiful. But today I'm just using her pussy because of her age, she's only 19, so just a little older than Claire.

I'm about to blow my load by the time I get to the bed. Seeing Claire wearing her panties full with my cum was just too much.

Carla is nice and wet as usual when I drive my cock in, but it takes three or four thrusts to get it all the way inside her, she's a tight little thing. She has the most perfect pussy I've ever felt around my cock.

"I can't last long Carla, it's too good," I say.

"I don't care, just do me hard, I want it hard today."

I grab onto her waist and give her five more thrusts as hard as I can, the bed screeching across the wooden floor a few inches. Then I flood her fuck hole with a bigger load than even I expected. I've already filled Claire's panties before breakfast.

Carla can't get enough of my cock, and I know she loves a good quick fuck like that.

It's very handy having her around the house so often. It helps me get my unnatural urges for Claire out of my system by having another teenager to fuck on demand. The fact she's a beauty queen is a very nice bonus.

"Are you staying over tonight?" I ask her.

"Yep, Ben is going to get pizzas and we're going to watch a movie."

"Come into me during the night," I tell her.

"But what about Laura? Won't she mind?"

"Don't worry about her. Just come into me when everyone is asleep, OK?"

She just smiles back.

Carla and I come back down the stairs into the living room to join the other three again.

"Do you want some coffee sweetie?" my wife says to Carla, as she starts pouring her a cup without waiting for a response.

I notice that Laura hasn't bothered fixing her robe, and her tit is still on show. Ben is stealing glances every few seconds.

"You up for a run Dad? Maybe before lunch today?" he says to me.

"Sure, perfect day for it. Claire, you wanna come too?"

"Not today Dad, I'm going to the mall with Mom and Carla, I need some new clothes," she says, and gives me a filthy smile.

Ben and I do a long run today, and both of us are wiped out afterwards. We get back before the three women, so it's just the two of us in the house.

"You want me to fix you some lunch?" I ask, when he comes back to the living room after taking a shower.

"Sure Dad, sounds good."

Ben relaxes in front of the TV, and I make a start on some pasta. I'm about to serve up our lunch when there's a knock on the back door.

"Hey Tom, is Laura home," my sister-in-law Emma says when I open the door, then steps into the house before I even have a chance to answer her.

"Hey. No she's not here at the moment Em," I say back, my cock giving a little twitch when I look down at her body as she walks past me. Black yoga pants, pink sleeveless tank top, white sneakers with her bare ankles showing. Sex on fucking legs.

"Oh, where is she?" she says, rolling her eyes, her demeanor completely changing from her friendly greeting when I opened the door ten seconds ago.

"The mall. But you can wait here for her to get back."

"Eh, no thanks. I think I'll pass," she says wrinkling her nose while giving me a disdainful look, and goes to turn back towards the door to leave.

"That wasn't a question," I say smiling. "Hang around a while." I place my right hand on her ass, my middle finger sliding in between her legs, and give her a little push, guiding her gently back into the kitchen. Her ass is pure perfection.

"What the fuck do you think you're doing?" she snaps, then stops walking.

I pull the waistband of my shorts down over my now erect cock with my left hand, keeping my right on her ass, squeezing her rear end and pushing my fingers further in between her legs. I start stroking my cock slowly.

"You going to put up a fight today? I like that."

"You're such a fucking asshole Tom."

But she doesn't move, she just looks down at me stroking myself. I take my hand off her ass and bring it up to the back of her neck, then steer her over to the countertop next to the kitchen sink. When we get there, I push her neck downwards towards the counter, then wait for a few seconds. When she sees I'm not progressing things further, she realizes I'm waiting for her. She had placed both of her hands on the counter, but she reaches them back and hooks them into the waistband of her yoga pants and thong, and pull them down baring her ass.

"Nice. Pull your ass cheeks apart for me." She does, straight away.

I remember one time when Emma was 18, maybe 19, and she was getting ready for a night out on the town with her friends. She wore the shortest skirt I had ever seen at the time, and I couldn't stop staring at her legs and ass, imagining what she would look like if only she raised that skirt up a couple inches.

Well right now I'm seeing exactly what I fantasized about all those years ago. It's even better in real life. I kneel down behind her and lick her asshole, sticking my tongue into it. After giving it a few swirls, I stand up, then taking my rigid cock in my hand, I point it at her slit and enter her pussy from behind. Soaking wet and loose as usual, just the way I want Emma.

I'm well aware Ben is sitting on the other side of our open plan living space, but Emma doesn't seem to have realized yet. I look over and I can see that he is sitting up and staring right at us.

"Hey Ben, you want to have some fun with your auntie Emma?" I say over to him loudly.

"WHAT? Ben, how long have you been there? Fuck no," Emma cries out.

"I don't remember anyone asking for your opinion," I say to her quietly.

He stands up hesitantly, and walks around the back of the sofa towards where I'm slowly screwing his sexy aunt.

Emma is loving getting it from behind like this by the way, she's panting like a dog.

"Shit, Ben, oh my god. Tom, what are you doing?" she says, starting to panic when she sees Ben approaching.

Ben is not even bothering to hide his boner in his shorts. He even starts to squeeze it through the material.

"Relax Emma. It's just Ben. He needs some relief too you know."

"Ben, what are you thinking. I'm your aunt for Christ's sake. You're mother is going to be so pissed at you," she says to my son.

Ben doesn't seem too bothered by her threat. Instead he pulls his stiff cock out of his shorts and takes another step towards his aunt. It's only a few inches away from her face now, he's tall so his cock is above the top of the counter.

"What are you waiting for Emma? Make your nephew feel better. You know you want to."

She does want it, I can feel her hole grip me a little tighter. Also, she won't refuse anything I tell her to do. She made that crystal clear that night at her house.

When Emma reaches out her left hand, she wraps it around Ben's cock and starts stroking him gently. Then without needing any more "encouragement", she leans her head down and wraps her mouth around his prick.

"Oh God, this is crazy. Oh fuck," Ben whispers to himself. He can't believe his luck. He's getting his cock sucked by his milf aunt. The lucky fucker probably dreamed about this. Aunt or not, Emma is one seriously hot piece of ass. If he's anything like me, Emma being his aunt was probably an added bonus for his fantasies.

We carry on like this for another minute, but we realize we're in an awkward position, with Emma bending herself sideways.

"Let's move this over to the sofa," I say. Nobody says anything, but we all move at the same time.

Ben sits down on the sofa, and Emma kneels in front of him, then immediately swallows him ball deep. He leans his head back in pure ecstasy. I kneel down behind her and ram my cock into her pussy again. She still has her pants on, just below her ass, but she must want a bit more movement as she uses both hands to pull them down completely, and off over her feet after kicking her running shoes off too. She keeps bobbing her head on Ben's pole the whole time.

We stay in this position for maybe five more minutes, when I say, "Ben, let's swap over." Emma doesn't say a word, she wants him inside her.

Emma stays on her knees while Ben and I swap places. I'm looking at his reaction when he moves in behind her and sees her perfect round ass ready for him. There is pure hunger and lust on his face. He mauls her ass first before doing anything. Emma has already started giving me a blowjob. She might have pretended she didn't want Ben, but the slut loves it.

She stops sucking me, and even lifts her mouth off my cock. Her eyes are closed, he must be starting to enter her.

"Oh God, I can't believe this is happening. You're such a bastard making me do this. He's my nephew Tom.......," then she roars loudly, climaxing on Ben's cock when he's fully inside.

Ben doesn't say anything. He just gets to work on her pussy, and is pounding her hard within seconds. The noise of his balls slapping against her clit and mound are so loud, it's not surprising neither he nor Emma don't notice Laura come in through the back door. I see her though, I have a view of the door from where I'm sitting. I give her a little wink and a smile. She just glares back at me. I suppose I am sitting here with my cock halfway down her sister's throat, maybe expecting a friendly hello is asking a bit much.

"You're so hot auntie Emma," says Ben. "I jerked off thinking about you last week."

"Oh Jesus," Emma moans, her pretense of unwillingness beginning to fade. "Harder Ben, good boy."

At that, Ben starts pounding her harder than I've ever seen anyone fuck in my life. His aunt looks so small with his hands holding her waist in position, while he rams her from behind. She even had to take her mouth off my cock, such is the force he's giving it to her.

Laura is looking on as her son mercilessly pounds Emma, her younger sister. She's standing behind Ben, and only I can see her. She has that familiar wide-eyed glint that tells me this is turning her on, despite what her folded arms and pursed lips are trying to portray.

"I hope you three are enjoying yourselves," Laura eventually says. "You're all fucking disgusting. Ben, she's your aunt, you should be ashamed of yourself."

"Oh shit, mom, I'm so sorry, dad started it, and I....I...," Ben stutters, while trying to cover his raging stiff cock now that he's pulled it out of Emma. The little shit throwing me under the bus as he tries to worm his way out of trouble with his mom.

"Spare me Ben. You're fucking sick. How could you," Laura yells at him.

Emma hasn't bothered moving. Instead she sinks her head back down into my lap and takes me down her throat again, right in front of my wife, her naked ass still on display. Such a naughty girl.

"Oh don't let me stop you," Laura says to Ben when he goes to stand up. He hesitates for a second, but then continues to stand. But Laura shows what she really wants then when she gently places a hand on his shoulder as he is half standing. Ben freezes, unsure what to do, but he quickly realizes what's happening.

He slowly gets back down on his knees and takes hold of his aunt's waist again. He had gotten a little soft I noticed, but his cock inflated back up to bursting point again when his mom put her hand on his shoulder.

Ben slowly enters his aunt again, not taking his eyes off his mom as he looks up over his shoulder at her. He's probably unsure of what her reaction will be.

Laura is wearing a pair of faded blue tight denim shorts, showing off her amazing tanned legs and feet in her sandals. On top she has a white spaghetti string top with a strapless bra underneath.

When Ben increases his fucking pace a bit, Laura takes her hand off his shoulder and walks around him to sit on the sofa beside me. She is looking very hot, her white blonde hair in a high ponytail which is swinging behind her as she walks. She crosses her arms and legs when she sits down less than a foot away from me. Emma looks over her sister without even bothering to take my cock out of her mouth. Both sisters just stare at each other for a good few seconds.

I place my hand on Laura's thigh, feeling the smooth sexy skin of her toned leg under my fingers. She doesn't say a word.

"This is fucking crazy," Ben grunts out quietly while shaking his head in disbelief, as he starts to pummel his aunt again.

We continue spit roasting Emma like this, with my wife looking on for another few minutes. Seeing my 19 year old son screw his 36 year old aunt is a seriously hot sight to look at. What I wouldn't have given to fuck someone like Emma when I was 19, a real, mature woman with experience beyond my 19 year old self's wildest dreams.

Suddenly Ben says, "I'm close auntie Emma, can I come inside you?"

"Oh no you don't," Laura says before Emma has time to lift her face off my cock. "Last thing we need is you knocking her up."

"I'm on the pill Laura, obviously," Emma says after lifting her head up, a string of drool and my precum connecting her bottom lip and the tip of my cock.

"Well just in case, come over here Ben. You can shoot it in my mouth," Laura says to her son.

Emma is flabbergasted. She is kneeling on the floor with her mouth hanging open, her left hand still holding my throbbing pole.

"What? I don't trust you to remember to take your pill every day with three kids distracting you. I'm not letting this ruin his life, or my furniture," Laura says defensively.

"Anyway, it's not like I haven't had his cum in my mouth before," Laura says to me. "What's one more load."

Emma's eyes go wide when Laura said that, and she momentarily pauses her amazing blowjob. But she decides not to get involved, and just takes me down into her throat again.

Emma is obviously on the pill like almost all women, otherwise she would be pregnant constantly with the amount of cum dumped into her. But I don't push it with Laura.

Before anyone has another second to think, Ben pulls his long cock out of Emma's loose pussy and jumps to his feet. He quickly steps around his aunt and up to his mother on the sofa, who uncrosses her legs as she leans forward. Laura places her hands on the sofa cushions either side of her knees, which she has kept together. She bends her upper body forward at the waist, tilts her head back and opens her mouth for our son.​
