Proof of Concept: A Cunning Plan

Warning: Gay/Pegging in the first starting bit. Whilst It is a small part, it is largely integral to the plot. I would appreciate you guys reading it, but understand if you don't!

"Mom! Come on!" Luke grunted his hips slamming back and forth, his cock diving deeper and deeper into his mother's tight pussy. His hands were pulling his hips down ferociously as she screamed into the ball-gag forced inside her mouth. Her pussy was glistening wet and dripping cum from the last time she had been fucked. Luke had been sliding his cock in and out of her pussy for a good half hour and he had built up quite the tolerance, "You know what we want!"

"I'd give it up Mom," Alex said trying to be the nice girl as she straddled Claire from behind. Claire's arms were bound behind her back, her tits tied together with a piece of rope, straining them. Alex slapped the blonde's plump motherly ass leaving a bright red hand print. Leaning forward, Alex pressed her soft pillow like tits against her mother's back, her erect nipples poking her shoulder blades, "I'll do it again… I know how much you moaned the last time!"

Screaming into the gag, Claire felt Alex's thick strapon cock rest against her tight arsehole. She had felt her strapon inside her ass before and it stretched her hole to lengths she never wanted it to be stretched to. Phil and her had always enjoyed anal, but Alex took it to extremes. Pretending to wait for objection from Claire, Alex smirked and pulled apart her mother's arse cheeks, before pressing her fake cock against Claire's asshole. With one swift push, she buried the entirety of her plastic cock inside, her mother's asshole, savouring the tight warmth, even though she couldn't feel it.

"I bet Dad never takes you this roughly," Alex remarked as she spanked her own mother. Alex wore a tightly red leather corset that pushed her tits upwards and made them seem even larger than they already were. The red leather harness for her strapon framed her tight and plump ass perfectly and made her ass jiggle with each pounding thrust she made into her mother's ass. As she mentioned her father, she was suddenly reminded of where he was.

Gay/Pegging

Looking across the room, Alex saw her Dad bent over the kitchen table, his legs spread wide and his hands bound to either side, leaving him spread eagle. His voice was muffled by a thick cock sliding past his lips and burying itself inside his throat. Manny's podgy frame eased his hips back and forth, sliding his thick Latino cock in and out of the older man's mouth. Panting loudly, Manny thrust harder and faster, pounding in and out of Phil's mouth.

"Suck his cock, bitch," Haley snapped as she brought a whip firmly down on her father's nipple, causing him to shake and spasm. Haley took the form of a dominatrix. She wore a matching black outfit to Alex's, except her cock was an extra inch long and she wore knee length boots. Jerking her cock as she strode around her father she struck her whip down a few more times, leaving red markings across his skin. All he could do was scream into Manny's cock, spluttering saliva around the fat little boy's sizable cock, "I don't think you're really trying! Perhaps this'll help!"

"Striding around to his ass, Haley parted his ass cheeks and pressed her cock against his asshole. Screaming into Manny's cock, Phil felt his own daughter slowly penetrate his asshole. Phil kept it a secret his affinity to gay men. He was in fact bisexual. Despite this, he never thought he would be in a position where he had hips lips tightly wrapped around Manny's cock and his own daughter behind his ass slowly sliding thick black cock inside his asshole.

Grunting as Manny slide the entirety of his cock down his throat, Phil waited for Haley to continue forward. His asshole parted even further as, she eased deeper in. Four inches, six inches, eight inches. The cock disappeared inch after inch, burying the thick plastic inside his asshole. Ten inches and finally twelve inches. The entire cock was lodged in her father's ass and Haley couldn't help, but feel a strange sense of perverse pride for her father. It was quite accomplishment. Pressing the coarse leather against her father's pert, hairless bum, Haley leaned forward and gently twirled her father's hair, "You like it… don't you?"

Manny continued to slide his cock in and out of Phil's mouth, enjoying the tight wet feeling of the older man's mouth. Yeah he would prefer one of the sister's to be suckling on his cock, but Manny would take Phil. His mouth was delightful.

"You know you like your darling daughter fucking your tight ass… Mom loves Luke and Alex's cocks… she wanted them remember… you wanted me as well…" Haley moaned loudly, the vibrator buried up her ass, shaking away, sliding even further, "Well have me!"

With that she drew he cock out and slammed her hips forward, causing Phil to scream into Manny's cock. The house was filled with pleasurable grunts and moans. A strange sight indeed.

One Month Earlier

"What do you mean!" Haley exclaimed watching her mother charge around the kitchen grabbing thing after thing trying to get ready to leave. Dressed in a tight fitting grey pinstriped pantsuit, Claire did her best to ignore her eldest daughter exasperated with the current argument.

"I said no," Claire said grabbing her bag and sliding it over her shoulder, "You haven't done anything to earn it. If you want a car, you can pay for it yourself."

"I don't have any money!" Haley argued trying to stop her mother from leaving her and avoiding the argument. She had been trying to get a car for a few weeks now and her mother was adamant in her positon and was showing no signs of faltering, much to Haley's fury.

"I'm not doing this again!" Claire said pushing past her daughter and striding down the corridor towards the door. As she opened it, her youngest child, Luke appeared at the stairs an innocent begging look upon his face, "What do you want now? Money?"

"Me and some friends want to go away in a few weeks and I need some money," Luke said trying to appear innocent and play to his mother's loving caring side.

"How much?" Claire said suspiciously as she searched through her bag for her car keys.

"Two hundred dollars," Luke said timidly knowing full well that this was too much to ask for. As he suspected, Claire scoffed and opened the door.

"Not a chance, Luke! Now you two behave. Dad will be back soon and you two are to stay upstairs and let him work!" Claire said shouting down to Haley who was still fuming in the kitchen. Disappointed, Luke turned and headed back upstairs. Leaving the house, Claire left the two children alone in the house and walked way to her car.

Grumbling to herself, Haley stormed upstairs pushing past Luke in her anger. She really needed that car. She looked like an idiot driving around with her mother and father. Yeah Dylan had his own car, but she didn't want have to be chauffeured around everywhere. It was humiliating. Angry, she lay down on her bed contemplating . Perhaps if she asked her father. He was always more persuadable.

Waiting patiently in her room, she finally heard the door open and her Dad enter the house. She waited for him to call up the stairs, asking who was home. What he normally did, but the house remained silent. She sat there for a minute, but nothing. Her dad had entered the house and said nothing. It was strange to her. Really strange.

Sliding out of her bed, she crept down the stairs hesitantly. Peering into the living room she saw her Dada fiddling with the TV connecting a cable to it that ran towards his laptop. Intrigued, Haley sat on the stairs, making sure she wouldn't be seen. Phil continued to fiddle around eventually, until the TV display came on showing a very interesting scene. The shower. It wasn't a live feed, but it was recorded video. Interested even more, Haley leant closer trying to see just what was happening.

Phil clapped his hands together excitedly before turning around and sitting on the sofa. Unbuckling his belt, Phil pulled out his cock. It was still soft, but was hardening slowly. Haley's eyes widened as she saw the length and size off her father's cock. His had to be six inches soft and as it slowly hardened to full length, she looked on in awe as it reached at least nine. Biting her lip, she couldn't help, but feel naughty watching her daddy gently stroke his cock.

Casting glances up the stairs to see if Luke was watching, Haley leant back against the wall and hiked her skirt up slightly to reveal her panties. She was planning on meeting Dylan later and had dressed accordingly. A pair of black lacy panties and matching bra. Pulling the fabric aside, she slid a finger up and down her slit, gently teasing herself. Biting her lip to stop her from moaning, Haley watched her Dad. While, Haley was leaning back, Phil had taken his clothes of leaving him naked. Much to Haley's surprise, her father had quite the figure. Lean with hints of a six pack lingering on his chest. He had an unshaven chest, which strangely aroused Haley even more than she already was.

Sitting back down, Phil had positioned himself so that Haley could no longer see his cock. Disappointed, Haley crept slowly down the stairs and hid behind the wall that separated the living room from the hallway. Here she got a clear view of her Daddy's stroking hand, gliding back and forth over his cock as he played with himself. Reaching over to the TV remote, Phil pressed play and Haley watched as the timer in the corner started rolling and the video began to play.

It took a minute before anything happened, but eventually movement began onscreen. The door opened and someone's elbow popped in shot before disappearing. Haley heard her mother's voice, in the video saying, "Are you sure? In here? What if the kids hear us?"

"They won't if we're really quiet, besides the water will drown most of our noises out," Phil whispered before his arm reached in and turned the water on. As the water began to flow, Phil stepped into the shower, his cock already hard. His hand was jerking it back and forth waiting for Claire. A moment passed and Haley saw her mother toss her bathrobe to the side and step into the shower. For a moment, Haley was taken aback. Her mother was quite hot. She had never really realised. She had nice smooth, creamy skin and a set of perky, full tits. Her ass was round and plump, but didn't sag. And now she had her hair wet, she looked hotter than ever, "Well? Shall we begin?"

Her mother gave her father a sultry look before sliding down into a squatting positon, the water falling down over her body, leaving it shimmering and glistening. It took a moment for Haley to realise what she was watching. Her mother leant forward and pressed her lips softly against Phil's cock, before parting her soft motherly lips and taking Phil's engorged, pulsating cockhead into her mouth. Phil groaned as Claire took his cock into her mouth and began suckling away. She bobbed her head back and forth across the very tip of his cock, making sure to drag her lips softly across his hardened flesh. Her tongue wrapped its way around his length ticking and playing with every sensitive crevice.

Haley almost forgot that her Dad was jerking off on the sofa watching himself get a blowjob. In a way it was kind of hot. Haley watched her Dad slide his hand back and forth over his cock, watching Claire suck him off in the shower. Casting her gaze back to the video, Haley saw her mother start to take more into her mouth. Shifting her position so that she was resting on her knees, Claire opened her throat up and slide down his cock, taking inch after inch into her hot wet mouth. She had had enough practice with Phil to lose he gag reflex and she put this to good use. She was able to take Phil's entire length into her throat with ease, as she demonstrated unwittingly to her watching daughter.

Pushing her husband's cock all the way into her throat, Claire finally pressed her lips against Phil's crotch. Holding herself there, she flexed and constricted her throat, squeezing his cock, while her hand slid up to his balls, gently fondling them. Playing and squeezing them.

Haley was well into playing with herself, sliding two fingers in and out of her pussy while watching her father jerk of to himself and her mother. Her pleasure ridden trance was interrupted when Phil spoke to himself, "Oh Claire… I can fuck you any day… lets sample some more forbidden fruits…"

Using the remote, he fast forward, letting Haley catch frames of him sliding his cock into his mother's pussy before spurting cum all over her pretty blonde face. Phil stopped the video, to show the shower empty once more. Looking at the time stamp, she could tell this was two days later. The sound of the door opening, sounded from the video and smaller arm reached in to turn the water on. Haley watched as the mysterious figure disrobed and then came into view of the camera. Stepping into the shower, the figure was revealed.

"Oh Alex!" Phil moaned his jerking speeding up slightly as Haley's nerdy little sister stepped into the shower, the water gliding over her skin. I say little, but Alex had grown into quite the woman. Like her mother, it was only now that Haley was realising just how hot her sister had become. She had massive tits, far bigger than hers and her mothers. Haley could even wager they could give Gloria a run for her money. Despite being very large, her tits hung perfectly and showed no hints of sagging. Each one was capped off nicely with a cute little nipple. Haley watched as her sister rubbed he water all over her body, down to her breasts. Alex massaged her soft globes before tracing her fingers over to her nipples. Gently playing with them, she brought them to stiff and erect peaks, before sliding her hands down her stomach.

Haley was trying her best not to moan, and was quickly becoming more and more aroused by her sister. The fact that her dad was jerking off to her sister was an immense turn on and she was fingering herself with passion. Watching with bated breath, Haley saw her sister's hand slide down her curvaceous hips and down her smooth legs. Alex had turned herself so she was bent at the waist presenting her arse unknowingly to the camera. Phil and Haley got good looks at her flesh bum cheeks and the sweet delicious holes within. Her puckered asshole was winking at the two of them and her pussy glistened wet from the water flowing down her body. Turning back around, Alex showed a front of view of her pussy. She had trimmed her hair into a small line leading up from her clit.

Her hand slid down to her clit and gave it a few rubs before reaching over and grabbing some shower gel. Without even thinking, Alex squeeze a long strand of the gel across her breasts before rubbing the liquid in, creating a thick soapy lather that covered her body. Phil moaned loudly as he watched his youngest daughter massage every inch of her body covering herself in soap, "Mmm… so hot…"

Haley agreed, but chose to keep her silence and instead continue watching the video, three fingers now pumping in and out of her tight pussy. Keeping her mouth shut, she pictured her sister's naked form. The sound of the shower filled the room as Phil continued to watch Alex in the shower. Suddenly the shower stopped and Haley grumbled to herself before peering back around to the TV and seeing the video fast forwarding. The time stamp changed to a week later and the video sped through. Instead of stopping at the beginning of the new shower experience, Phil fast forwarded to his favourite part.

Stifling a gasp, Haley saw Phil stop the video. Two people were in the shower and loud grunts and moans filled the room as they got down to it in the shower. It was Haley and Dylan. She remembered when the video was. It was a week ago, when she last say Dylan. They had the house to themselves and they spent the day walking around naked and fucking. They ended up in the shower cleaning themselves and ultimately fucking again. Looking at the video, Haley smirked before continuing to play with herself.

There was something so hot about watching herself get fucked. The faces she made, the grunts and moans slipping out from between her lips. Phil groaned loudly as he let the remote drop and he let his second hand begin to massage his balls. He was close to cumming and was speeding up his jerking as he watched his eldest get fucked.

In the video, Dylan had picked Haley up so she had her long, tanned slender legs wrapped around his hips, his cock submerged in her tight teenage pussy. Her hands clung to his neck as he pinned her against the wall. Her face was agape with pleasure as moans an orgasmic grunts came from her lips. She caught glimpses of Dylan's cock as he pounded into her with slow, powerful and forceful thrusts. Every few seconds he would pull out and slide back in. That was how she liked it. Slow and hard. It also helped when Dylan had a nice cock. A little shorter than her Dad's, but thicker by far. It stretched her to new lengths every time they fucked. Haley and Dylan's moans were timed perfectly with each time, he slammed his hips inwards making sure to force his cock deep into her teenage cunt.

"Naughty, naughty Haley…" Phil groaned watching his daughter get fucked in the same shower he fucked his wife, "Oh… what I would give to punish you…"

"Punish me Daddy. Punish your naughty little daughter," Haley moaned beneath her breath, lucky that the wet slaps of his cock were drowning out her tiny whimpers and helpless moans.

Dylan's hips pounded in and out, the wet slaps of their shower fucking echoing around the room as Phil neared his orgasm. Haley however was mesmerized with her own face. The sexy looks she was making as Dylan speared her on his cock, making her moan louder than ever before. She remembered this time in the shower well. It was one of the hottest and most pleasurable times they had sex. Dylan murmured something in Haley's ear, before sliding his cock out of her pussy and letting her down. Crouching down in the shower, Haley opened her mouth and began to massage her pert young teen tits.

Furiously jerking his cock, Dylan groaned loudly, spraying rope after rope of cum over the young Dunphy girl. Grunting loudly, he watched as he painted the young girls face with thick white cum. She smiled and let the cum land on her face and into her mouth. Swallowing what was left in her mouth, she rose to her feet and gently jerked his cock with her hand, "That was amazing baby…"

"I know…" Dylan panted, recovering from his orgasm and admiring his hot girlfriend plastered with his cum, "What shall we do now?"

"Well… I want you to eat me out on my parent's bed," Haley suggested, before the pair of them left the shower and ran off to fuck in her parents bed. As Haley said this, Phil grunted loudly, covering his chest in his cum moaning Haley's name loudly. Close to her own orgasm, Haley sped up her fingering only to be interrupted by the door being unlocked. Panicking she sprinted up the stairs and around the corner before peering back down. She saw her mother entering holding an unmarked black shopping bag. Curious, Haley crept back down the stairs as Claire entered the living room.

"Ooo… you jerking of too Haley again?" Claire purred as she joined her husband on the couch and licking some cum from his chest, "I managed to get the stuff for our little roleplay. The hair dye, the cute little girl panties and bra. I got it all. Even the stuff for my little fantasy."

"Mmm, I can't wait," Phil moaned, breathing heavily as he tried to recuperate from his masturbation session, "Are you sure you wanna do the whole Luke thing?"

"Yeah! There are some interesting positions, I'd like to see him in!" Claire said taking the bag and hiding it away under the stairs so now one would find it, "Now I was thinking we could act out your fantasy tomorrow night when the kids are at their grandparents and we could do mine the next day? They'll be staying the whole weekend so we'll have plenty of time."

"Sounds like a plan," Phil said pushing up from the couch and grabbing a towel from the laundry pile, "Suppose I should go pick up Alex then?"

"That would be great," Claire said as she strode into the kitchen to start making dinner. Haley had a mischievous look on her face. If her parents wanted to act out their perverse little fantasies, perhaps they'd prefer to actually perform their fantasies. She would gladly help her father out, but her mother would be harder. She'd have to get Luke in on the plan. If that worked she would get her car and Luke would get his money. Smiling, she cast a look back over to the TV and saw the scene had changed again.

Luke was standing in the shower jerking of with a pair of panties. A pair of Haley's panties. Letting her hand drop back down to her pussy, she noticed the top right hand corner. The video feed was live. He was in the shower right now. Smiling to herself, Haley readjusted her outfit and walked back up the stairs. Arriving at the bathroom she leant against the door, hearing grunts and wet slaps from within. Smirking to herself, she dropped her hand to the doorknob and slowly twisted it. The door opened slightly and the noises grew louder. Then, she entered…
