-----------------‐------------------------------------------------------------------------------------------------------

I wake up at 8am on Saturday morning alone in bed. Despite only getting a few hours sleep, I feel on top of the world.

I'm pretty grimy after my late night activities, I just got straight into bed after running home from Emma's house. But I don't bother showering now either. I wanted to leave her smell on me for longer.

"Good morning sexy," I cheerfully say to my wife when I come down the stairs and into the kitchen.

Laura is sitting on a high stool at our countertop, sipping a cup of coffee. She looks bad.

"I'm never drinking again," she quietly says back.

"Yeah yeah, that's what we all say," I reply, laughing. "I'm going to the gym, do you need anything from the store? I can stop off on my way home."

"Yes actually, I need a few things for the barbecue later. I'll text you a list," she says, as she reaches for her phone. "Working out again? Wow, you really are taking this new lifestyle seriously, aren't you?"

"Trying my best," I say, giving her a kiss on the lips as I go to leave. "Love you."

"Love you too Tom," she says back.

-------------------------------------------------------------------------------------------------------------------------

The gym is very quiet, which is exactly what I want. No distractions, just a hard workout.

I shower there when I'm finished, then check my phone. There is a text waiting for me from Laura with a few items to get for later.

When I get to the store, the parking lot only has a few cars dotted around, so I get a spot close to the door.

I grab a basket and start making my way around picking up the things Laura wants. I'm trying to decide which type of cheese to get when another shopper catches my eye.

She is in her late 20s I think, 5'7" would be my guess, wearing workout gear. Black yoga pants with white gym socks pulled up high over the lower legs. A white short sleeve running top, and a white baseball cap, with her brunette pony tail sticking out the back.

She is a very attractive young woman, with the most sexy full lips you can imagine. I think back to what Emma said last night, "use who you want to use, just take them."

No time like the present. There is nobody else around that I can see. I leave my shopping basket down, walk up behind sexy lips, take her by the hand and make my way into a storage room for staff a few feet away, pulling her along. She makes a little noise in surprise, but she doesn't protest, and just walks along a step behind me as I lead her by the hand. She knows what I want.

I close the door to the small room behind me. It's just a closet they keep some cleaning stuff.

Squatting down, my head level with her hips, I notice she is still holding her basket. She sees me looking, and bends to leave it down on the ground. I reach up and grab the waistband of her pants, then pull them and her thong down. She has her brown bush nicely trimmed.

I stand up, my hard cock sticking out obscenely in my loose fitting sweat pants.

"Turn around," are the first words I say to her.

She does what she's told, and she doesn't need any further instructions. She leans up against the wall, and arches her back just enough so that her pussy is presented to me, easy for fucking.

I immediately push my wide cockhead inside, and she swings her left hand back off the wall onto my hip, trying to hold me off.

"It's too big, holy shit. Give me a second," the brunette says.

She looks so hot with her baseball cap still on, a lock of her dark brown hair hanging down the side of her face.

We wait a few seconds, then she takes her hand away from my hip and puts it back on the wall, bracing herself.

"OK, try another bit," she says, her breathing shallow. "I've never taken one this big before. It's so thick."

She's getting wet, and I notice her pussy is starting to loosen, adjusting to my size. But I take it slow with her.

A few slow plunges later and she's ready for a fucking. She has her knees close together, both slightly bent, and I'm squatting down a little bit so that I keep my rod in line with her.

When I'm sure she is able to take it all, I pick up the pace and get into a steady rhythm. I'm pulling her ass cheeks apart, looking down at her ass hole, sizing it up. I'm not sure she will be able for a cock of my size up there, it was hard for her pussy to take it. So I just play with it a little using my thumb instead.

"Oh god, I don't think you'll fit up my ass," she says when I push my thumb in. "But you can try if you want."

"I just want your pussy," I say back.

I'm really giving it to her hard now, and her breathing is getting faster.

"Yesss, yes Daddy, fuck me hard," she says as she cums.

OK, I've never been called that before. I'm not that much older than her, so I give her ass a slap. That triggers her to spasm again, and call me daddy again!

Seconds later, I shoot the first splash of cum into her pussy, without any warning. Then I pull out and spray the rest of my huge load on her back, under her training top that I'm holding up. Some even lands on the straps of her sports bra. I hope she has a change of clothes, she's drenched.

The girl is still leaning against the wall with her pants around her ankles as I reach to open the door.

"Thanks," I say, and slap her on the ass again, then close the door behind me.

I pick up my shopping basket and get the last couple of items Laura wants. Then I pay at the checkout, and leave.

I wait in the car to see the girl leave too. She comes out ten minutes after me, walking very slowly and gingerly, with the wet patches clearly visible through her top where it sticks to her back.

Smiling, I start the car and drive home.

-------------------------------------------------------------------------------------------------------------------------

Ben texted his mom to say they will be here in 10 minutes, he's leaving his girlfriend's house now.

"I really hope she's a nice girl Tom," Laura says to me. "Ben deserves someone who will treat him right."

"I'm sure she's perfect, honey," I say.

I'm cleaning off the barbecue, it's been ages since we used it. It's a really nice day with hardly a cloud in the sky, a perfect day for eating outside.

Claire is in her room studying for an exam on Monday, but she said she would join us when the food is ready.

The barbecue is just lit when I hear Laura's car pull into the drive. Ben borrowed it to go and collect his guest.

He walks around the side of the house, and opens the little gate leading into the backyard. Ben walks through first, and holds the gate open for his girlfriend.

This is the first time he's brought a girl home to meet us, so it must be serious.

Laura is standing beside me holding onto my arm, squeezing a little tighter when she sees the side gate being pushed open.

Her long bare legs, toned and tanned, catch my eyes first. Fuck they're nice.

She's wearing a short baby blue summer dress with a small white flower pattern all over. It pinches in at the waist, and comes to about half way down her thigh.

When I look up to her chest, my eyes almost pop out of my head. Her tits are out of this world. The dress dips down at the front, showing a nice amount of cleavage, not too much. But tits like this can't be hidden. My pole is rising just looking at them.

A few locks of her long black hair hang down around her breasts. I manage to tear my eyes away from her magnificent tits, moving up her flawlessly tanned upper chest, to her neck, then I look directly into her eyes...

Shit.

"Mom, Dad, this is Carla," Ben says excitedly, introducing his girlfriend to us both.

Oh shit shit shit.

Carla is looking back at me, her mouth open in shock. I'm rooted to the spot, still holding the tongs for the barbecue.

"Oh my god, it's so nice to meet you," Laura says as she strides over to Carla and gives her a hug.

I'm dumbstruck. What the fuck can I say here?

"Hello, nice to meet you, I'm Ben's dad, Tom," I say finally, as I walk over to shake her hand.

"Nice to meet you Tom," she replies, taking my hand after the few seconds she needed to pull herself together. She was just as shocked to see me.

Even her hand is sexy. So soft and small in mine.

Ben asks everyone what they want to drink, then he takes Carla inside with him to show her around.

"Is that who I think it is?" my wife asks, while barely moving her lips. Then she gives Carla a little wave and a smile when she looks out the window at us during Ben's tour of the house.

I just nod. I'm not able to bring myself to say yes.

"I thought so, after seeing both of your reactions," she says. "Well, your description of her was on the money."

"Looks like I have some competition," Laura mumbles to nobody in particular, then walks inside.

Everyone is sitting around the outdoor table, chilling out. Claire has joined us, and she is chatting to Ben and Carla. I'm at the barbecue finishing off the food, when Laura asks everyone what they would like.

"I'll have a burger and a hotdog, Mom," Ben says.

"Just a burger for me please," Carla tells Laura.

"Oh Carla, are you sure you won't have a hotdog too," my wife says smiling. "Tom has a footlong simmering with your name on it?"

Carla blushes, then politely declines. Laura can be wicked when she wants to be. Claire takes the hotdog instead, two of them in fact.

I join them at the table when everyone has their food, and sit down beside Ben. Carla is the other side of him, with Claire opposite her, and then Laura across from her son.

"So Carla, tell us more about you," said Laura. "Are you in college, or do you work?"

"I'm in Ben's class in college, that's where we met," Carla says.

"So you're the same age as Ben?" I say, my voice squeaking.

"Yes, I'm 19," Carla replies, looking directly at me.

I was certain she was at least 25 when I banged her last Monday. Jesus, if you asked me her age now after seeing her again, I would say at least 25 if I didn't know. Not a teenager!

I need to get away from here. My head is starting to spin. I've screwed my son's 19 year old girlfriend. I've royally fucked up this time.

I suddenly stand up, banging my thigh off the table by accident, almost knocking it over.

"I just need to use the bathroom," I say, as I walk towards the back door.

When I get there I close and lock the door behind me. I splash cold water on my face in an attempt to clear my head. All sorts of thoughts are running through my mind.

What if Ben finds out...Will he ever speak to me again... Will Carla tell him... Carla is one seriously sexy woman, those legs, and tits, her beautiful face... Stop thinking about your son's girlfriend like that... What will Laura do when she gets me on her own... Imagine Carla on all fours in front of you in that dress, like she was in the gym... Stop it, stop it...

I walk out of the bathroom, not feeling a whole lot better. Back in the kitchen I get a drink of water. I'm standing at the sink after gulping down half a glass when I see a reflection in the window of someone behind me. I spin around, and Carla is standing there. It's just the two of us.

"Why didn't you tell me you were only 19," I say to her quietly.

"Well you didn't seem too worried about my age when you asked me to fuck," she spits back.

"I thought you were much older than 19. Maybe 25 at least," I say.

But it's pointless, I don't even know what I'm arguing about. I think I'm just lashing out in a panic.

"Don't worry about it," Carla says. "I'm not complaining. I'll never forget your cock for as long as I live. It's like a fucking fire hydrant."

"You can't talk like that Carla, you're dating my son," I say. "Just forget it ever happened."

"Forget? How can I forget about this," she says, as she reaches out and grabs my stiffening cock through my shorts. "It's all I can think about."

"It's never happening again. What about Ben?" I say, a little louder now.

"Ben is great, but he can't measure up to this," the little sex goddess says, giving me another squeeze.

We stand in the kitchen for another minute. I don't know what to say, or do. But she's still holding and squeezing my cock through the material as it grows in her hand. I strain my neck back to look out the window. I can see the other three are still out back sitting around the table.

"We have to stop this, NOW," I say, looking into Carla's eyes.

Then I walk out of the kitchen and go upstairs to the master bedroom. I need a minute to cool off, and soften.

When I walk back outside, Carla is sitting at the table beside Ben again. Laura stares at me, very suspiciously.

"Hey Dad, Mom said it's OK if Carla stays over tonight. Do you mind?" Ben says to me.

Yes, I mind that a lot.

"Sure thing Ben, she can stay over anytime," I say back.

-------------------------------------------------------------------------------------------------------------------------

Laura and I go upstairs to bed early, leaving Ben and Carla to watch some TV on their own. After I bumped into Carla in the kitchen earlier, the rest of the evening passed without any drama.

I'm still awake, but Laura fell asleep as soon as she climbed into bed. I can feel myself begin to doze off when I hear a sound coming from Ben's room, which is next to ours. It's a slow, barely audible squeaking noise. I listen for a while just to make sure, and yes, it's his bed, they're having sex. Great.

Here I am on a Saturday night, listening to my son having sex with his girlfriend. Shouldn't this be the other way around? He's the fucking teenager, not me!

The noises from his room are going on for a while, and all sorts of images are forming in my mind. I'm remembering my time with Carla, and how unbelievable it was. She is the most beautiful girl, woman, I've ever had sex with, ever seen in real life! The flashbacks are not helping, because now the whole situation is starting to have an effect on me.

As I lay on my back, I can see the sheets forming into a tent before my eyes. I need to do something about this. Laura is on her left side with her back to me, snoring softly. She's wearing a matching short-sleeve silk button top and shorts.

Luckily the shorts are very short, and I know she isn't wearing anything underneath as I watched her put them on an hour ago.

I strip off my boxer shorts, so now I'm completely naked under the sheets. I slide over behind Laura, and pull the left leg hole of her shorts upwards, giving me access.

I don't bother waking her up before I push my cock into her pussy like this, while lying on my side behind her.

She starts to stir after a couple of short thrusts, then looks back over her shoulder at me and smiles.

"Hey, do you need a little relief babe? You go right ahead. Do you mind if I go back to sleep while you do your thing?" my wife says.

"Sure. Thanks hon," I say, and I continue slow fucking her.

I'm enjoying the wonderful feeling of my wife's amazing pussy, while listening to Ben slowly screw his girlfriend next door for a couple of minutes, when Laura speaks again.

"Are you fucking me because you're turned on listening to Carla get fucked by our son?" she asks.

I don't answer. I just carry on doing what I was doing, ignoring her.

"That's just weird. You're a sicko Tom," she continues on.

But her pussy just suddenly soaks me.

"Shut the fuck up. I'm imagining you're Carla, and you're ruining it for me by talking," I say.

I can feel her pussy clench and grip me tight when I said that. The dirty bitch loves it.

Pulling my cock out, I turn Laura face down, flat on the bed. I climb on top of her legs, grab her shorts with both hands and rip them apart, fully exposing her holes to me.

I roughly knee her legs apart, take hold of my rock hard cock in my right hand and line it up with her pussy. I push the tip inside, then placing a hand on either side of her body, I lower myself down on top of her, pushing my cock fully up her cunt as I eventually lay flat on top of her, my belly on her ass.

Then I fuck her senseless. I fuck her as hard as I've ever fucked in my life, burying her face into the pillow and pummeling her body into the mattress.

I take my weight off her and pull her up into a doggy style position. Then holding both of her arms up at her hips by the wrists, I continue ramming her hard. I'm grunting like an animal, but it's nothing compared to the noises Laura is making, and she's not faking it.

I slap her ass hard, once, twice, then a third time, her right ass cheek is a burning red. But I continue my onslaught on her pussy. And yes, I'm imaging it's Carla the whole time.

"That's it Carla, take it, you're pussy is so tight," I say between grunts.

Laura is lapping this up.

"You know how to take my cock. You're such a better fuck than my wife," I say.

That tips her over the edge, and she squirts her pussy juice everywhere, gushing back all over me and the bed.

I stick my cock back in, and let her ride out her climax, then I kick up to full speed again and keep going. When I'm nearly there I pull out, pick her up by the armpits, and throw her around onto her back.

I stick my cock that's about to erupt back into her pussy for a few final thrusts, then when I'm just about to come I pull out, quickly crawl up over her chest. Kneeling on the bed with one knee either side, I fire my massive load all over her face.

I've never come on her face before. Her beautiful face. The face men stare at longingly and lustfully. It's completely covered in my white cum. She's a mess, one eye glued shut, it's in her hair, up her nose, one huge glob is hanging from her chin as she props herself up on her elbows.

The sense of power it's given me is intoxicating, and addictive. I've marked her and defiled her, and she fucking loves it. I can see it on her face, underneath the coat of cum.

"Is it OK if I go clean up?" she asks me, a few minutes after I've climbed off her chest.

I don't even answer. I just close my eyes and fall asleep.

There is silence coming from Ben's room now.

---------------------------------------------------------------

If Ben heard anything last night, he doesn't mention it on our early Sunday morning run. Laura, Claire and Carla were all still in bed when we left the house.

We return to find Laura and Carla having breakfast together. Claire is still in bed.

Carla's eyes immediately go to my crotch and I can tell she wants it bad. She definitely heard it in action last night.

"Guys, Max just messaged me. He needs a ride to work at the grocery store. Mom, is it OK if I borrow your car? I'll go collect him and drop him off. Carla, I'll be back in 30 minutes at most," Ben says.

Carla smiles and nods back at Ben.

"That's OK, I'll just hang out here with your Mom and Dad until you get back," Carla says.

Then he grabs the keys and leaves.

"I'm gonna jump in the shower," I say back over my shoulder as I start climbing the stairs.

I wonder will she take her chance. She might be afraid to with Laura around, that's the only problem.

Stripping off my sweaty running clothes in our bedroom, I walk naked into the en suite. I step into the walk-in shower and turn on the huge shower head coming down from the ceiling.

The cold water that comes first is refreshing, and is just what I need to cool down after my run.
