"We should do something nice this weekend, just the two of us. We never go out anymore," says Laura.

It's Friday night, and we're in the sitting room. Laura is watching some brain rotting reality show nonsense on TV. I'm wasting my own brain away in equal measure scrolling on my phone.

I come to my senses and leave the phone down, then say to Laura, "You're right. Let's do something tomorrow night. Dinner? Then hit a bar? Or how about we go to the movies?"

"Oh I'd love to see a movie. It's been sooo long since we did that. Let me look at what's showing."

We decide what to see, well Laura decides really, but I'm easy, I'm just looking forward to an evening out.

Laura changes the TV over to a streamer and we watch an episode of a pretty good show both of us like.

When it's over I get the sense Laura wants to say something.

"I'm worried about Claire," she starts to say, after switching the TV off. "She hardly ever leaves her room except for school, or to go hang out at one of her friend's houses. I'm not sure how well she is adapting to the world now she's 18."

"She's just trying really hard with her school work. She's fine," I say, but now I'm not so sure. Laura is normally better at gauging things like this. "I'll have a word with her, and try to see of she's OK."

"Thanks Tom, she might open up to you. She's always been a daddy's girl," says Laura.

"I'll talk to her tomorrow, it's getting a little late tonight."

That's when I hear the back door close and look around to see Ben arrive home. Ben and I have really been cranking up the training intensity this week. Even more importantly, there has been no tension between us since everything that happened last weekend with Carla.

"Hey Mom, hey Dad," our son says as he sits down on his favorite end of the sofa. "Why is the TV off?" he asks, which is a reasonable question. It's never off!

"Your father and I are just talking," Laura says to him.

"Weird," Ben says, reaching for the TV remote.

Laura just looks at me and smiles, then scooches a bit closer and rests her head on my shoulder.

"OK, are you going to get a room, or do I need to leave?" Ben says jokingly.

Laura play kicks him on the leg, but can't stop herself from laughing. All three of us sit there, Laura has laid down on her back now, with her head on my thigh. Ben is channel surfing while lying on the L end of the sofa. He eventually stops on a college football game.

Laura groans, then says, "Ah not this crap. I'm going to bed if you leave this on."

Suddenly, there is a knock on the back door.

"Who could that be, it's a little late for visitors," Laura says.

"Sorry, I forgot to mention Carla is coming over. She's going to stay the night. Is that OK?" says Ben.

"Of course it's OK," Laura says.

Ben jumps up and opens the door for his girlfriend, then both of them walk over to the sofa. Ben takes his usual seat again, and Carla sits down beside him. Laura has sat up now so there is plenty of room.

Carla is looking amazing as usual. She's just wearing her casual sports clothes, grey yoga pants and a long sleeve training top. She looks stunning in anything she wears.

All four of us sit and chat for the next half hour or more. Then Ben makes a move to go to bed.

"I'll just take Carla for a few minutes before you two hit the hay," I say.

Talk about a mood killer. Nobody says anything. Ben sits back down, and Laura doesn't move.

"Go on up to the master bedroom Carla, you know which one that is, I'll be right up."

Carla doesn't hesitate, she walks up the stairs as all three pairs of eyes follow her.

"You better not make a mess, I'm not changing those sheets tonight," Laura says, then grabs the TV remote and switches back to her reality show.

Ben doesn't say anything.

When I'm done with Carla, she uses the en suite, picks her clothes up off the floor, then leaves our room and walks naked to Ben's, his room is next to ours.

We didn't take long and we didn't make a mess. When I came inside her, she grabbed her panties to catch my load when I pulled out, before it gushed out onto the bed.

I assume Laura and Ben knew we were finished when the noise stopped, and they would have heard Carla moving between the rooms. Laura came up to bed a few minutes later. She went straight into the en suite and I could hear her taking a piss, then she came out dressed for bed wearing a pair of short cotton shorts, and a t-shirt.

I'm still naked under the sheets after Carla, I was just going to sleep like this. When Laura climbed into the bed, she lowered herself down under the sheets. Suddenly I can feel her warm mouth take my soft cock in. She swirled her tongue around every inch of it, licking off all the dried up cum and pussy juice. I think she likes tasting other womens' pussy, or maybe it's just Carla's she enjoys.

She takes her mouth off me just as I was starting to get hard, rolls onto her side facing away from me, flicks off the bedside light and says goodnight.

Five minutes later I can hear the now familiar bed squeaks coming from Ben's room. I don't remember them stopping, I must have fallen asleep.

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

Next morning at 6am Ben and I go for a long run together. Everyone else is asleep when we leave. We run past Emma's house on our route, but I don't see her, or anyone else inside. Running past her home makes me think about her, and even while running I get a twitch in my cock.

Putting my sister-in-law out of my mind, we finish off our run and get back home at 7.30am. I can't believe I'm able to run for that long already.

Claire is the only one up when we get back, she's eating cereal in the kitchen. Ben goes straight for a shower, but I hang back to chat with my daughter. I can't just dive straight in with my concerns, so we talk about all sorts of general stuff, mainly school.

Then suddenly Claire gets up and seems in a hurry to get back to her room. So I walk along with her, I'm not missing my opportunity to speak to her, plus I don't want to have Laura going on about it again.

"OK Dad, nice chat, but I need to study now," she says as I follow her into the room.

"Claire, your Mom and I are worried about you. You spend so much time in your room, we're worried you don't get out enough."

"Dad, I'm fine. I have so much work to do if I want to get into any of the top colleges."

"I know, I know, but you need to be more balanced," I say.

"I am balanced. I hang out with my friends all the time. I was over in Sara's house yesterday!" she says, getting a little annoyed with me.

"You need to get outside more. I can't remember the last time I saw you get some exercise," I say calmly.

"Just because you decided last week to get fit, doesn't make you an expert," she snaps at me.

"Listen, I know. I'm just worried about you. Why don't you join me and Ben on one of our runs?"

"What, are you serious? No way. You two stink when you run. Gross," she says, but she has calmed down a little bit.

"OK, well it would do you a lot of good. It will give you so much more energy. And it will help your studying, nothing beats the fresh air for clearing your head," I say, even convincing myself.

"I'll see."

"OK, I'll take that," I say, smiling at her and giving her a hug.

"Get off. Go take a shower," she says, trying to push me away.

As I hug Claire, I'm looking over her shoulder and something catches my eye on her bed. It's sticking out from under her pillow, and I know immediately what it is. Laura has the exact same one, it's a vibrator. Oh shit, I don't need to see that.

I know she's an adult now, but she is my little girl. I don't want to think about her doing anything like that. I need to get out of here.

"I'm going, I'm going. Just make sure you think about coming out with me and Ben," then I turn and leave as quick as my sore, tired legs will carry me.

Saturday turns out to be a nice relaxing day lazing around the house. Carla comes over mid-afternoon, and she spends most of the time on the sofa with Ben, just talking and laughing. Laura and I sit with them for a while, and it was nice getting to know Carla better and hearing about her family.

I wouldn't have been able to sit so close to her and have a conversation like that a few days ago, without wanting to screw her. I think our arrangement has taken the overwhelming urge to fuck her at every opportunity away, and with that pressure lifted we can actually spend time together as a family, including Carla as Ben's girlfriend.

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

Laura looks amazing for our date. She's wearing a pair of skin tight light blue jeans, white sneakers, and white tank top, with her white blonde hair in a pony tail.

The movie theater was full when we arrived. As usual, Laura gets a lot of attention when we go out in public. Very few other women are in her league. It's clear we're on a date together, so most men leave her alone. But it doesn't deter a few.

We find our seats around the middle after squeezing past a few people in our row. Laura is ahead of me so takes the farthest of the two seats, sitting down beside a man around our age.

He's there with a female partner of roughly the same age. His jaw hits the floor when he sees Laura about to sit down beside him. That gives me a little buzz if I'm honest.

The two seats beside me are empty when we sit down.

The movie is about to start when I notice the man beside Laura has placed his hand on her thigh. A bit forward, but who could blame him, she is beyond tempting. Laura seems to just be ignoring him, and he seems happy enough to just cop a feel.

The movie starts, and about five minutes in I get curious to see what's going on beside me. So I lean forward a little, for a better look, and I notice the stranger's partner has his cock out and is giving him a slow handjob. While he has his hand on Laura's leg still.

Maybe 10 minutes after that, Laura shifts slightly in her seat, leaning over towards the other armrest instead. So I take another look at what's going on. He still has his hand on Laura's leg, but now my wife has reached over into his lap and has her hand wrapped around the base of his cock. She isn't even looking at him, she's still watching the movie. His partner has leaned down awkwardly and has taken him into her mouth. Her lips touch against my wife's hand every so often when she bobs her head down far enough.

This seems to be as far as they're going to take it, until the guy leans his head towards Laura. She turns away from the screen and they start making out. His partner is attractive, but not on the same level as my wife.

They keep this going for another few minutes, then I see him place his hand on top of the other woman's head in his lap. He holds her down while he jerks his hips up into her face as he cums into her mouth, not breaking his kiss with Laura. I've missed about fifteen minutes of the movie because of all this.

My wife seems content with her work when she shifts her body to lean back over to me now, and rests her head on my shoulder. We manage to get to the end credits without any more distractions. Just another regular night at the movies.

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

Laura is speaking to her sister on the phone. I can only hear the odd whisper, but can't quite understand what they're saying. I wonder is Emma spilling the beans on me and what I've been up to with her. Well, it's all going to come out sooner or later.

It's Sunday morning, and Ben and I have already finished our early morning run. Claire didn't come with us, which is disappointing.

"Jack and the kids have gone to stay with his parents for the weekend. Em had the house to herself last night, she said it was amazing! Bubble bath, and some binge watching TV. When am I getting a break from you lot?" Laura says then laughs.

"Is she on her own again tonight?"

"Yep, they don't get back until early tomorrow morning," Laura tells me.

Interesting.

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

After finishing our meal on Sunday afternoon, Laura says she is going for a nap. I give it a few minutes, then I jump in the car and point it in the direction of Emma's house.

I let myself in, as I have gotten used to doing recently. I walk in the front door, and through to the kitchen at the rear. No sign of Emma. So I walk down the hall and stick my head into the sitting room. There she is.

"Fucking hell Tom, you have to stop sneaking around. You're scaring the shit out of me," Emma says, clearly startled.

She's sitting on an armchair in her robe with her feet up on a footrest, reading a book. I don't answer her. Instead I walk over to where she's sitting, and take hold of one of her hands. She leaves down her book and stands up. I take her other hand too, holding them both between us.

She has just had a shower or bath, her hair is still wet. She looks and smells so good. Lowering our hands, I step closer and kiss her for the first time. It's a gentle kiss, and it takes me a few seconds to realize it's actually happening. I'm actually kissing Laura's sister, I've wanted to do this for twenty years.

We share our gentle kiss for a minute, maybe two. Then it's Emma who can't contain herself any longer. She raises her right hand to the back of my neck and holds me firm, opening her mouth wide and pushing her tongue against mine. Her tongue feels so long she is shoving it that far into my mouth. It feels like its close to my throat, and it's fucking amazing. This really turns me on, and my cock makes itself known for the first time of the evening by rising up between us, poking her in the leg.

Emma brings her hands up to the belt holding her robe closed, unties it, and opens it for me, then lets it fall from her shoulders. She's not wearing anything underneath. It's the first time I've seen her completely naked, and it takes my breath away. I have to calm myself down to hold off ejaculating as I stand here.

I pull my gym shorts down over my fully hard cock, then let them drop to the floor.

"I knew you'd come here tonight," Emma says.

"What do you mean?"

"I knew you would come to me. When you heard I was here alone. That's why I called Laura this morning," she says, smiling. "I knew this would make you come," she says, tapping her forefinger on the tip of my cock.

"Suck it," I say. "I want to feel what your mouth is like."

She does what she's told and drops her naked body to her knees before me. She sees how big I am up close now, at eye level, and I can see the fear. But that only lasts a split second. Then I see pure, animal hunger.

I always imagined Emma taking my full length down her throat when I jerked off thinking about her. I knew chances are that would not be very realistic, not many women can take one this big. She is always so demure and ladylike, it was fun to think about her being such a sex mad whore. Little did I know she's even more filthy than my wildest dreams.

I've seen the real Emma in the bedroom now, and that Emma is wild. Yeah, she'll fucking take it all down alright.

She holds it by the base in her right hand, and takes my balls in her left. Then opens her mouth and engulfs the tip, then four inches, slides it back out to the tip, then takes it all down like I knew she would, like a good little slut. She hold me like that, but uses her tongue and throat to massage my entire cock. I've never felt anything like it.

"I'm cumming, Emma, I'm cumming," I mumble.

She pulls me out of her throat, and keeps the tip and an inch or two of my shaft in her mouth, then squeezes my balls softly with her hand.

I've held on for as long as I can. I know this is going to be a massive load, I haven't emptied my balls since Friday. I can't remember the last time I've gone that long.

Putting my hands softly on each side of her beautiful face, I just let it happen. The first spurt often startles some women, but not Emma. It's a huge splash of cum, but Emma lets it hit the roof of her mouth without even a slight flinch. Then they start firing out in quick succession. She has her lips sealed around my prick, and she doesn't let a single drop escape.

But there's just too much to hold in her mouth, and I see her gulp down a mouthful as I continue shooting more into her.

Then another gulp. And finally a third when she feels I've finished. She gives my tip a few swirls with her tongue, then lifts her mouth off. I need to sit down.

I want to fuck her. I want to spend every second I can inside her. But she drained me so good my legs are like jello. I'm normally ready to go again quickly after cumming. Sometimes without even losing my erection.

But after a suck like that, I need to take a minute. I feel light headed.

Emma gets to her feet, and reaches for her discarded robe, but I catch her arm to stop her.

"No, stay as you are," I whisper.

I'm sitting on the sofa, looking directly at her pussy. Her mound is covered in neatly trimmed dark brown hair.

I reach out my right hand, around her side and onto her ass. After gently caressing her left cheek, I pull her towards me, just the last step between us, and lift her smooth left leg upwards. She places her left foot on the sofa beside me.

Then without any hanging around, I bury my face between her legs. Emma immediately pulls my head tight against her, holding me with both hands as she stays standing. I'm licking and sucking everywhere. There's probably something you should know about me - I won't win any prizes for my skills going down on women. I love doing it, but I'm just not very good at it. Well that's what I've been told anyway.

But I need to get this out of my system, I've longed to taste her, to stick my tongue in her most intimate place. And she tastes fucking good. I'm probably getting more from this than Emma.

I settle down after a couple of minutes and I move my right hand off her ass, bringing it around to her pussy.

I keep lapping with my tongue, and insert the middle finger of my right hand into her pussy. She's wet, very very wet. I don't think I've ever felt such wetness before. My finger slips in so easy, I immediately put a second one in, and quickly follow that with a third.

For the next minute I enjoy exploring her with my fingers, pushing in far, then pulling towards the front.

Suddenly, Emma takes her foot off the sofa. I pull my fingers out and they're dripping wet. She sits down on the sofa where her foot just was, lifts her feet up onto the cushion towards her ass, and spreads her legs. I get the hint, and dive right back in face first. I can get my tongue further into her in this new position.

"Use your fingers," Emma breathes.

See what I mean, I'm not very good.

So I take my face away from her snatch and it's covered in her juices, up around my nose and down to my chin. She tastes delicious. A lot like Laura.

I stick the same three fingers back in and start curling them inside her, which she seems to like. I have my left hand on her soft inner right thigh, slowing stroking it up and down.
