I stretched. My body was aching. I had lost count of the number of times I had cum over the last thirty-six hours. However, it was Sunday; no work today... only fucking.

I rolled over; Lou was awake. She was sitting up, her hair cascading over those voluptuous breasts, her face betraying the fact that she was still half asleep. "Shower?" I asked her. She smiled.

"Shower, then coffee!" she laughed as I sat up.

After showering and pulling robes on, we started downstairs. As we were about halfway down the stairs, we could hear a familiar-sounding voice coming from the ground floor. "That’s it, baby, lick me there. Make me wet. Aaagghh. Make me wet for them. Uuhhh!"

We turned the corner into the lounge. Kneeling on the floor was Lucy, her head between the legs of Lexi; she was looking directly at us, a smile played across her face as she pinched her nipples. "Morning! Happy birthday... Daddy!"

"What the..." I managed to get out as Lexi continued smiling at us, maintaining eye contact.

"Come on. I'm just like you both. I'm horny all the fucking time. This isn't the first time that I have had Lucy between my legs, but I guess that's something else we have in common, isn't it?"

With that, her head lolled back as she groaned loudly. The lapping sound from between her legs continued as Lucy's head continued to bob up and down.

I took a moment to look at Lexi. She was wearing your stereotypical schoolgirl outfit: a short tartan skirt, knee-length white socks, a fully undone white blouse, and a matching school tie loosely tied around her neck. One foot was stretched out; the other was cocked up onto the sofa.

It was the first time I had seen Lexi's breasts; I had only ever seen them through a crack in the door as she watched Lou and me fucking at night. They were magnificent; so like Lou’s, I would so like to get my hands on them to mash my face between them and suck on their heavenly nipples.

I felt stirrings as my dick was hardening. Lexi opened her eyes. "It looks like you're both enjoying the show; look, you're getting hard... and look at Mum."

In that moment I had forgotten about Lou; I turned and looked at her. She had opened her robe and was openly rubbing her pussy as she watched what was going on, already panting with excitement.

Watching this, the taboo nature of what I was seeing, knowing it was wrong... and yet we knew we both wanted this. We had discussed this openly when we made our fuck-it list. Lou's hand slowly stroked me; she whispered in my ear, "Is this a dream?" Are we really watching this? Are we really going to do this?

I looked at Lou, my wife of so long, the wife that I shared everything with, including, it appeared, our daughter. I smiled and looked back at the scene unfolding in front of us. When I spoke, my voice was more powerful than I thought it would be.

"I know you like watching us, don't you, Lexi? Playing with yourself on the landing as we have sex." As I said this, I undid my robe, shrugging it off my shoulders to the floor. Lou, a split second behind me, followed my lead. "You like spying on us at our most intimate moments, and now what? Do you want us to punish you?"

My words did something to Lexi; she smiled at me, licking her lips... and then she opened her mouth.

"Please daddy, I want to touch your dick, feel it throb in my hands, feel the cock that created me in me. Then I want you to fuck me; I want to feel you fill me up. I want you to use me, to make me your cum dump, and to fill me with your hot seed."

She turned, her eyes pleading as she looked at Lou. "Please! Please, Mummy, let Daddy ride me. I have been bad; I have fucked so many and been fucked by so many, and he needs to punish me, to discipline me. Fucking me is the only way. Although I don't think it will make me stop, I can't... aaaggghhh, fuck, Lucy, that's so good. Don't stop doing that to me!"

We crossed the room in a couple of strides. Lou joined Lucy between Lexi's thighs, instantly starting to lick and lap at her soaking thighs. I stepped onto the sofa, standing over her.

I reached down and grabbed the tie around her neck, tugging her up to level with my balls. "You know what to do; now get sucking." Lexi did not need any second invitation, as she grabbed me in her hand and started to take me in her mouth. First she took one ball into her mouth, then the other while she stroked me, twisting her hand as she moved up and down.

She then gently tongued the precum droplets that had formed at my urethra before taking my cock into her soft mouth. I could feel her tongue stud rubbing on the base of my dick as she lapped at me. At the same time, she was moaning around me. Her mother was licking and sucking at her clit. Lucy had moved up to her breasts, groping and sucking at her nipples.

My hands went to her head, yanking at her pigtails as I started pushing my hard cock further and further into her throat. "Ughmph, ughmph, ughmph." The room was filled with the slurping sounds of me fucking her face. Tears were flowing from her eyes, and drool pooled on her lips.

It would have been quite the sight if someone had walked into our front room at that moment, three people taking advantage of this woman. All I wanted to do at that moment was be inside Lexi, to feel her cunt around my dick, to see her below me, her eyes screwed up in pleasure.

I pulled myself out of Lexi's mouth with a satisfying wet pop, a string of saliva from her mouth connecting to my cock. "Lie down," I ordered her. Lou climbed out from between her thighs, Lexi's juices running down her chin.

Lexi lay back on the sofa as I climbed between her legs and began to rub my dick up and down her lips. I knew that she would be open for me, that I would be in her in one swift move. "You want this, don't you?

"God, yes!"

"It's not the first time you've been fucked, is it?"

"No, Daddy, it's not; I fucked...." Before she finished her tale, I pushed fully in one swift move. "Oh my god, Daddy, you're so hard... aaagggh... it's like I'm fucking steel... Mummy, he's so big."

Lou had moved around and lowered herself onto her face; Lexi started to suck at her mother's pussy, and Lou's head instantly rocked back.

Lucy was kneeling next to Lexi, her face in her lap as her tongue darted out, catching her clit and my dick as I increased my pace, fucking my girl.

My hands went to Lexi's tits as I squeezed and pulled at them. "Oh fuck Daddy, squeeze my tits. I love them being pulled; it makes me so wet. Make me gush from my cunt. "Fuck me, Daddy. Fuck me hard. Fuck me like the slut I am," her muffled voice cried in pleasure.

I kept my pace up, hooking one of her legs over my shoulder. "God, Mummy, he's so deep... breed me, own my cunt!" I looked up at my glorious wife, one hand braced by holding the back of the sofa, her other hand rubbing her own clit, Lexi's tongue probing her. Lou's eyes closed in bliss. I could tell she was about to cum and cum on the face of her daughter.

Lucy had now sucked Lexi's clit into her mouth but briefly looked up. "She squirts; she squirts just like Lou." Lou and I both looked up, our eyes locking for a moment.

I pushed roughly into Lexi. "And how would you know that?" I hoarsely asked her.

"I fucked her in your bed. I fucked her until she came; I fucked her until she blacked out!"

Like mother, like daughter, I thought.

I could see that Lexi was starting to fall apart. The confident young woman that we all knew was now losing control. Her back was arching, her feet flapping like she was trying to swim; her hands spasmed as her cunt exploded, her ejaculate drenching our thighs.

At that simultaneous moment, Lou came with a huge orgasm, squirting into the face of the girl she had birthed.

I could feel Lexi's cunt walls contract as she continued to cum. A surge of pleasure had rolled through her. If the pleasure she had been experiencing before were waves, her orgasm was a tsunami blasting through her body.

At that moment, I ejaculated, spilling into her in hot spurts. "Fill her, fill her pussy. She's just like her mother; make her your cum slut!" Lucy shouted.

Lou fell back against the sofa, spent after her squirting orgasm. I rocked back, my dick falling out of her, accompanied by a mixture of both our juices. Lucy went down on Lexi, starting to clean her up.

For a while, the only noise that accompanied our heavy breathing was the slurping sound made by Lucy. Lexi was lying there, a contented smile across her face, her eyes half open, her fingers twirling Lucy’s hair. To everyone, she said, "Fuck me... own me."

From the other end of the sofa, Lou spoke, her voice shaky but confident. "I need to have her."

Lucy sat up and then crawled over to one of the chairs. I watched her swaying bottom as she crawled; I do love that ass.

When she reached the chair, she retrieved something, which she put in her mouth, and then crawled back to Lou. In her mouth was a strap-on, which she offered to Lou.

Lou took the offered strapon, now an expert at putting them on. How much she had learnt during this year.

She sat between her daughter's legs, slowly starting to play with her labia as her thumb started to rub her clitoris.

Lexi whimpered as Lou softly stroked the folds of her pussy, Lexi's hand softly pulling at her own nipple. Lou leaned across her, her mouth nuzzling her neck. Lexi's eyes were closed, her mouth slightly open. "So long", she whispered, quietly but loud enough for her mother to hear, "finally."

Lou knelt up; she rubbed the pink phallus that she was wearing against her lips. Lexi made a mewing sound.

Lucy was seated next to me at the other end of the sofa; her hand reached for my hardening cock, and she started to pull at me. I kept watching as my wife fucked my daughter.

Lexi had already abandoned all restraint as she came quickly. Lou pushed through her orgasm, her hand pushing down on Lexi's abdomen. "Fuuuccckkk, Mummy, fuck, that's so... so... so... uurrghh." Lexi squirted again all over Lou.

I was now rock hard, a combination of Lucy's ministrations and the erotic taboo show going on in front of me. Lou looked across at me. Meeting my gaze, she grinned and then turned to Lexi. "Suck your Daddy, suck him until he comes in your mouth. Lucy... Come and sit on my cock."

Lucy stood up as Lou backed out of Lexi's soaked cunt. Lexi rolled off the sofa and crawled on her hands and knees toward me; as they passed, Lucy playfully swatted at her ass.

Lexi took my dick in her hand as her mouth enveloped the head. At the same time, Lucy straddled Lou’s silicone dick, sticky with Lexi's cum. "Aaagghhh, fuuucckk, fuck, fuck, god", her hand flicking at her clit as she quickly gathered pace.

The room was filled with the "slap, slap, slap" of skin on skin as Lucy impaled herself and the "splodge, splodge, splodge." The crude slurping sound Lexi made as she increased the speed and depth that she was taking me in.

From the other side of the room, Lucy came before flopping back against Lou.

"I'm going to cum, I'm... aaaggghhh." Lexi bobbed her head down until her nose was pressed against my abdomen. Rope after rope of fresh spunk coated her throat as she gulped it all down, swallowing every drop. "Good girl, Lexi. Good girl."

Lucy had crawled off of Lou, her chest heaving as she lay on one end of the sofa. Lou was leaning back but sitting up. Lexi was now sitting between my legs; quietly she said, "It's everything I knew it would be.”

We were all resting in post-orgasmic bliss, globs of liquid drying on our skin. It was Lexi who first spoke. "What now?"

"You told us you'd done so much, had been fucked and had fucked. Why don't you tell us all about it?" Her mother said.

Lexi sat up, the school tie the only thing she still had on, a smile playing across her face. "OK, let me tell you about when I lost a dare at the pub and ended up with a load of men wanking across my face."

The End... Well almost, one final chapter remains!
