Matt arrived home late, too late. He had been delayed on the train and delayed in traffic, and all he could think of was fucking some gorgeous ass. Squeezing his cock into a tight hole or two. Probably two if he knew his daughter well enough.

When he did walk through the door, he was met by a flourish of kisses as Em ran into his arms. Sandra leaned on the kitchen door and watched them cavort in the hallway. The afternoon’s session left her feeling slightly jealous. She secretly wanted to join them, but she waited, silently, until Em told her that she could.

After a good snog, Em finally turned to her mother and beckoned her over. Her hand went to the back of her mother’s head, and she pushed her towards her father so that they could kiss.

“She’s been good to me all day,” Em said.

“How many orgasms have you had already?” Matt asked.

“I lost count. At one point, I kept Mum between my legs for a whole hour, and she never stopped licking for one minute. It was heaven, Dad.”

Matt looked at his wife. He couldn’t comprehend the change in her, the submissiveness taking over completely as he saw her change into his daughter’s whore, for want of a better description. He felt odd, wondering to himself why he couldn’t have made that change in his wife. But it wasn’t in his power to do so; it was in another woman’s power to make Sandra behave the way she did. Sandra felt whole while giving herself to another woman and letting that woman control her. It just turned out that that woman was her daughter.

Matt slipped his arm around his wife and cupped her bottom, giving it a good squeeze. He noticed the tension in her face, the uncertainty as she made eye contact. She almost looked scared. Em could see her mother’s dilemma, too.

“Mum is so much looking forward to having your cock up her ass, Dad,” Em raised her eyebrows and smiled at her mother. “We’ve been practising,” Em added, “but it was only a small dildo.”

Matt smiled, lifted his wife’s skirt and fingered the rim of her ass.

“No knickers?” he said, surprised.

“She’s not allowed knickers in the house anymore,” Em said, “house rules.”

“House rules?” Matt repeated.

“Yes, and we’ve had a good chat today, and she’s agreed that anything you want, you get. So make the most of it, Dad.”

Matt unbuttoned his trousers and took his cock out, “better suck this, Sandra,” he told her.

Sandra looked towards Em, her raised eyebrows told her everything she needed to know and like a dutiful submissive, she dropped to her knees and started to wrap her lips around her husband’s cock. Matt shook his head and couldn’t understand how his daughter had this much power over her, where he had failed.

“Come on, you two, our evening meal is just about ready. Spaghetti Bolognese – quick and easy,” Em said.

Sandra stood up as commanded, leaving Matt to follow his erection into the kitchen behind his wife and Em. He smiled to himself, relishing in the newfound power he seemed to have over his wife, even if it was second-hand. He pushed his dick back into his trousers when his erection subsided.

The meal was wonderful, and they all nattered like a family should. The wine flowed too, though while Matt was holding back on the quantity, he could see that Sandra was getting her full quota of Dutch courage.

When Em came back from clearing the dishes, she placed her hands on her mother’s breasts from behind and whispered in her ear while squeezing them.

“Time for you to go upstairs and get ready,” she whispered.

Em was high on the power she wielded over her mother. Not that she was the one being dominant, it was more that her mother was truly, and one hundred per cent, submissive to her.

“Go on, off you go,” she said, indicating to the stairs with her thumb.

Sandra left them at the table. Em leaned in towards her father and kissed him on the cheek. When he turned to face her, the kiss deteriorated into a passionate exchange that left both of them breathless.

“What have you done to your mother?” Matt asked when they parted.

“It’s not me, it's her,” Em replied. “This is all her doing, following my orders, my wishes, my commands. She’s the one doing all of this. I’m just the conductor, waving my baton and getting what I want.”

“So, you’ve been naked all day?” Matt asked.

“Not only that, but she’s been licking my pussy ninety per cent of the time. At one point, I was having a continuous orgasm from the constant pleasure coursing through me. I’ve never felt that before, and it was wonderful.”

“Fuck, me, Em. You’re insatiable.”

Em laughed. “Come on lets go see Mum, I told her to get naked, get prepared, and wait for us while sitting on the bed.”

Matt and Em walked into the bedroom to see Sandra sitting on the bed as instructed, waiting with her hands in her lap. She glanced at Em as she walked in, hoping for recognition that she had been a good girl. Em nodded her approval and indicated with the flat of her hand for her mother to stand up and turn around.

Sandra complied while both Matt and Em removed their clothes.

Em’s hand found her mother’s breast first, and she kissed her neck and worked her tongue along it until she bit her ear. Matt followed his daughter’s lead and did the same. His hand came upon his wife’s bottom, and he couldn’t help but slip his finger along the crack of her ass, over her little star, and into her wet pussy.

“She’s soaked.”

“I thought she would be,” Em replied.

Sandra’s thighs parted of their own accord, giving Matt more room to manoeuvre his hand between them. It was what she was instructed to do from the sit-down chat that Em had with her before Matt arrived home.

He coated his finger in pussy juice and then slipped it into her anus. It felt tight, and he could feel her ass clench it before it even made it inside.

“Relax,” Em whispered in her mother’s ear. “Just relax.”

She moved in front of her mother and kissed her on the lips. “Just pretend it’s some wanton woman with a strap-on taking you from behind. Some tart from that club, Killing Kittens.”

Sandra sighed when Matt’s finger slipped all the way in. “Yes, that’s nice,” Sandra moaned, closing her eyes and leaning in to kiss her daughter. She involuntarily pushed her bottom back to meet the intruding digit.

Em squeezed her mother’s nipples between her fingers and thumbs.

Matt took some time out to undress while watching both of them caress and kiss on the edge of the bed. When he was naked, he presented his erect cock to his wife’s tiny opening. Pushing it forward just a little so that she could feel it ask permission.

She looked into Em’s eyes, pleaded with her to rescind her decision, but all she could see in return was excitement and pleasure.

“Fusk my ass,” her mother said, reaching behind her to spread her cheeks wide.

“Me first, Mother, you should know that by now,” Em said.

She moved to the edge of the bed and presented her ass to her father.

“This is how it’s done, Mother, watch and learn because you’re next.”

Matt stroked his cock in anticipation. He knew exactly how this worked. It was a simple case of presentation just to get started, hand on his daughter’s hips and push all the way in. His cock didn’t even require any lubrication because he knew that Em would have prepared herself for him well ahead of the lovely dinner they had.

Within a minute, Em was moaning and groaning and telling her father to fuck her as hard and as fast as he liked. Sandra looked on in amazement as Matt used his daughter like a rag doll, pulling back on her hips as he fucked his dick into her tight opening. Her pussy was gushing from the wild action, and it was everything Sandra could do to stop herself from burying her face in her daughter’s twat to suck it all up.

Em’s eyes rolled back as her first orgasm hit her hard. Her legs shook, and it was all Matt could do to hold on to her tightly and prevent her from crashing into the bed. Her hands grasped the bedclothes and crumpled them into her fists as she climaxed.

“Give me another one,” she cried out. “And Mum, get your cunt down here.”

Sandra moved quickly, scissoring her legs around her daughter's head and pushing her twat towards her mouth. Em sucked on her pussy while her father ploughed her ass to a second orgasm. It came much quicker than the first, which she put down to the fact that she was feasting on pussy at the same time.

When she finished climaxing, she slumped forward onto her mother’s stomach, breathing heavily and staring up into her dreamy eyes.

“Your turn, Mother,” she said, “be a good girl for me.”

Sandra looked at Matt, his cock still fully erect and proud of his body. She could see it ache for more of the same, and she could tell that she was in for a bit of a ride.

She approached the end of the bed, spread her legs a little, and turned to face her husband. Her daughter’s words spurring her on.

Em placed he pussy in front of her mother’s mouth.

“You may lick this if it will make you feel any better,” she said.

Sandra smiled, licked her lips, and then looked over her shoulder. “I want exactly what you just gave her. Nothing less,” she smiled, “now get your cock up my ass,”  she commanded, and then she placed the flat of her tongue on hr daughter’s twat and started lapping.

Matt couldn’t believe her words. Neither could Em, who moaned at the sudden oral pleasure as she witnessed the anal debauchery of her mother. She winked at Matt.

“Give it to her,” Em mouthed the silent words.

Matt’s cock had started to push past his wife’s sphincter. He shook his head, still not believing this intrusion was taking place, but he could see his dick disappearing. His hands grasped Sandra’s hips, and he pushed a little further. Em’s hand came down on her mother’s head, and she pulled her tongue into her needy cunt.

“What are you waiting for, Dad. Fuck her,” Em was relishing the pleasure and the sight of her mother taking her dad’s cock.

Matt took hold of Sandra’s hips and pushed all the way inside her tight little hole. When he was balls deep, he pulled back and repeated the action.

It didn’t take long for him to be on the verge of orgasm. He put it down to the fact that it was his wife’s arse, a place that his cock had no chance of penetrating, and yet it was. He repeatedly slammed his dick into her anus, not caring whether he made her climax or not.

Sandra lapped at her daughter’s pussy until a feeling deep inside her threatened to break loose. A feeling that her husband’s cock had never elicited in her pussy. Her legs started to shake, and she was rapidly losing purchase on the bed. She had to stop licking her daughter’s pussy, much to the dismay of Em, who was on the verge of her own pleasurable journey into bliss.

Sandra lifted her head off her daughter’s twat, looped her hands around her thighs, and gripped them hard.

“I’m fucking cumming,” she squeaked. “Don’t stop, this is so fucking good.”

“Told you that you’d love it,” Em smiled.

He leaned forward to hold her mother tight. “Give it to her, Dad.”

Matt looked on in awe. Both women instructed him to go harder, deeper, faster. He was fucking at full speed as it was, and his wife’s words caused him to lose all composure. He had never heard her be so verbal in his whole life. She was shaking below him, her legs vibrating like they were plugged into the mains electricity.

“She’s overloading, Dad,” Em cried. “She’s going from one to another, to another.”

Sandra knew that her daughter was right as orgasm after orgasm crashed over her body. Once one had started to subside, the next one grew so quickly that she didn’t have time to recover. Her gasps of pleasure merged into one another; her pussy was on fire even though it was her ass that was powering her orgasms.

Matt couldn’t believe the sight before him. He couldn’t believe that his wife was on a tightrope of sexual release, with each one threatening to make her pass out with pleasure. And then he lost all control of his own body. His orgasm hit hard. He plunged into his wife’s ass one more time and held his cock deep inside while he emptied his balls into her.

When he was sure he was empty, he pulled from her anus and let her legs fall flat on the bed. She was still shaking between her daughter’s thighs when he took a step back.

Em made a silent whistle with her lips and smiled at her Dad.

“Fuck me, that was intense,” she said. “That was something else.”

“Yes,” said Sandra, “that was something else. Something I have never felt in my life.”

Sandra climbed up her daughter’s body and kissed her. “Thank you so much for encouraging me to have anal sex. It was mind-blowing. I’ve never had orgasms like it. Thank you.”

Em embraced her mother while her dad sat on the bed beside her. He leaned over to kiss her, allowing his cock to brush against his wife’s ass once more.

“I’ve decided,” Em said, “that now anal sex is on the menu for you two, that you can share your bed again. I’ll move back into mine, and this family can get back to normal. As normal as it possibly can, that is.”

Matt felt an immediate sense of loss that he would not be sleeping with his daughter. His gaze rested on Sandra, who just nodded. She sobbed while letting a tear or two escape.

“Mother, stop that,” said Em, “Dad, you will still be fucking me, and we’ll be having those Friday morning blowjobs as usual. Mother, your pussy is mine, all mine, but since you’ve discovered a love for anal sex, then Dad can have your backside whenever he wants.”

The room fell silent for the first time that day. It was stares all around, and the consequences weighed heavily on all of them.

“Are you okay with that, Sandra?” Matt asked.

“Yes, I am. Let’s give it a go. Especially if those orgasms are repeatable.”

Em left the bedroom to go to her old room, paused in the doorway, and smiled at them both.

“You two behave, no arguing, no sulking, and no refusals,” Em insisted. She closed the door and left them to it, smiling all the way back to her own bedroom.

The silence nearly suffocated Matt and Sandra, and it was a few minutes before Sandra smiled and bit her lip.

“We have one hell of a daughter,” Sandra said.

“I agree,” Matt nodded.

Sandra surprised him by turning around and kneeling on all fours.

“Come on, fuck my ass again.”

“Really?” Matt asked.

“Really, because if I know Em, she’s listening at the door. Now, make me cum.”
