Chapter 1528 - MARRIED SISTER'S BIG TITS

My wife Karen and I were renting a nice house on the beach in Destin, Florida for a week with my sister Meagan and her husband Paul.

Karen and I are both in our mid 40's, while Meagan was 39 and Paul being a year or two younger than her.

Karen and I had done this several times in the past, but this was the first time for my sister and Paul.

I never really 'hung out' with my sister. We had separate circles of friends when we lived at home.

Meagan and Paul had two teenage boys while we had a son who'd already married and lived several hours from us.

With their kids staying with his parents for the week, we were all set for a week of hanging on the beach, margaritas, no work and no shoes.

We had only been at the rental for a couple hours when Meagan and Paul showed up. We all greeted each other and helped carry in their stuff. Once they were settled in we walked down to the beach.

My wife Karen is your typical mid 40's married wife. Just your average next door neighbor kinda woman. Not skinny, not fat, somewhere plainly right in the middle.

I'm by no means no one to write home about. I guess I'd use some of the same words to describe myself.

Paul was an almost skinny, tech savvy type of guy. He was always preoccupied with the latest phone or tablet in his hand.

My sister Meagan would best be described as an average looking girl with a bit of a curvy body and a very nice looking rack.

I'm always amazed at just how big her tits are on the few times a year we actually see each other and this time was no different.

We were all dressed in shorts and t-shirts and I found myself noticing again and again how Meagan's shirt was being held off her stomach by those big tits.

It was getting later and after watching the sun set we walked back up to the house. I fired up the grill out on the deck while Karen mixed up a batch of margaritas.

Soon we were all having a great time eating, drinking and telling funny stories about each other's daily lives.

With the drinks flowing I was noticing Meagan's big shirt covered tits more than I knew I should. I couldn't help myself as I don't usually have tits like that right in front of me. Luckily with everyone laughing and having a good time I don't think anyone caught on to me.

With none of us being big drinkers and having driven in from hours away it wasn't long before we were all calling it a day. We shut everything down and headed to our rooms. I can't speak for everyone, but I was out like a light.

Being use to getting up early I woke up around 5 am. I tried to go back to sleep but I was wide awake by then. I started caressing my wife thinking we might have a bit of fun but she woke up and told me she still needed some sleep after the drinks the night before.

I made my way out to the living room and layed back on the couch enjoying the view of the beach with the waves slowly rolling in. It was still awhile before sunrise so it was almost dark and eerily quiet.

As I lay there I couldn't help but to think about the way Meagan's tits looked in that shirt. I could feel my cock thickening as I did. The more I thought about that vision, which I couldn't stop doing, the harder I got.

I reached down and squeezed my dick through my boxers. Fuck, now I was getting horny.

It was quiet, everyone's still asleep, no one would know. I had just pulled my hard cock thru the opening of my boxers when I heard a toilet flush in another part of the house.

Damn, I fixed things back but my dick was still hard.

I sat up and grabbed a pillow from the couch and placed it over me in what I hoped was a nonchalant kinda way and then waited to see if someone came out.

After a few minutes here comes Meagan. She still has that same shirt on but the shorts are gone now, just blue panties. I'm guessing she doesn't see me as she heads to the fridge.

She grabs a water and takes a few drinks still standing with the door open. As she tilts her arm up to take a drink her shirt pulls up over her ass almost to the top of her panties. Damn.

I don't make a sound as she turns and closes the fridge and starts walking into living room while looking out at the beach.

The couch I'm sitting on is over to the side and it's still almost dark out so she doesn't see me but I can see her.

Her side profile is hot. Those big tits looked even bigger from those angle. I know I'm perving now but I'm the only one who knows and it's not like I'll ever reveal it to anyone.

Wow, I thought to myself, Meagan has a damn hot body with those thighs, ass, tits, and long brown hair. Right about then she turns and sees me.

A little startled she says "Dammit, you scared me" She then laughs a little and asks what I'm doing.

"Same as you" I replied.

She then came over and grabbed a throw blanket while sitting at the other end of the couch pulling that blanket over her lap in the process.

Looking out the big windows she said "Beautiful isn't it?"

I answered her that it definitely was.

We sat quietly for a few minutes. Then she got up to get her phone saying she wanted to get pics as the sun came up. I reminded her it was still a bit early for a sunrise.

As she was walking away to get her phone I could not keep my eyes off her panty covered ass with that t-shirt draped across the top of it.

My cock was getting hard again under that pillow. I figured I'd stroke it in the shower a little later.

As she came quietly walking back her big tits were bouncing under that shirt. She hopped back under that blanket and started messing with her phone.

I just said it before I thought about it. "No way those are real."

She looked up at me and said "What?" Not like she didn't necessarily hear me but more like she couldn't believe what I just said.

I then stumbled over my words as I said "Shit, I'm sorry, I think my filter is still asleep."

At that she looked back down at her phone and while still looking at it said "No they're not. I had them done several years ago. I thought you knew, everyone else did." After which she looked back up at me with a quick little smile then back down to her phone.

I blurted out "My compliments to the surgeon."

She looked back up to me and said jokingly "Hey now, most of these are real you know."

I replied with the old saying "They say if a guy can reach out and touch 'em then they must be real".

She laughed and then we were quiet again for a few minutes as she continued messing with her phone.

She then layed it down on the coffee table and sat back against the arm of the couch facing me and said "I'm guessing you're like all the other guys and you like big boobs."

I replied "Who wouldn't?" I then asked her if it was a big difference from before she had them done.

"Yes." She said. "The first thing I noticed was they were heavier."

"Any bigger?" I asked trying to be funny.

"Well, yeah." She replied.

I then mumbled that I wish Karen would do the same but quickly added "She's not the fun type though."

A few more minutes roll by and in my horned up frame of mind I said with a little smile "Would it be too weird if I wanted to feel what your 'enhanced' boobs felt like?"

To which my seemingly shocked sister answered with a slightly raised eyebrow "Do you really want to feel your sister's boobs?"

"Not if it's too weird for you." Then I added "Just curious what the difference would be."

She looked at me for several seconds then looked towards the kitchen where the bedroom doors were.

She then looked back at me. "You really want to?" She said

"Sure, I mean if you're cool with it, I'm not trying to freak you out or anything though." I replied.

"I guess but of course this goes without saying, you better take this to your grave."

I looked at her and said "Seriously, who am I gonna tell?"

She said "I mean it mister, if this gets out, I'll put you in a grave."

"Relax" I told her "You can put the shovel away already, no one's gonna know."

She looked at me lightly biting her bottom lip and said "Ok, scoot closer."

So I scooted over next to her feet that were still under the blanket.

Now I'm sitting about middle of the couch with Meagan on my left. She's sitting kinda Indian style with her feet and knees pushing against my left thigh. I've still got that pillow on my lap with my arms resting on top of it.

I then say "How do you want me to do this?"

She reaches over and grabs my left hand bringing it up to her shirt covered tits. She gently presses my hand to her right breast. She then moves her hand leaving mine there.

I start lightly squeezing as I asked "Is this ok?"

"Yeah." She said, looking over towards the kitchen and bedroom doors as she said it.

I found her nipple with my thumb and rubbed it side to side. I then said "Damn, I like that".

After a minute or so of this she says "So what do you think? Do they feel different than your wife's?" Those last two words barely a whisper.

I replied that I wasn't sure, it was hard to tell through the t-shirt. I kept rubbing my thumb across her nipple and it was starting to get harder and so was my dick under that pillow.

I then asked if they both felt the same. She didn't answer so I moved my hand over to the other one and began lightly squeezing and rubbing it.

Her tits were so fucking nice. Big, squeezable and her nipples were getting harder by the minute. I couldn't stop. I leaned toward her and put both my hands on her tits pushing them upwards and together while rubbing my thumbs back and forth across those big hard nipples.

My cock was throbbing hard now and I let that pillow fall to the floor.

A minute or so more goes by and she says "Getting carried away there, don't you think?"

To which I replied "Just a friendly comparison." I then repeated that it was kinda hard to tell with the shirt in the way.

She said "Michael, you are bad."

I tried reassuring her that I wasn't but I don't think she bought it.

Slowly I brought my right hand down a little and started pulling up on her shirt. She just looked me right in the eyes as she was again biting on her bottom lip.

I pulled a little harder. She didn't help me but she didn't stop me either.

I told her "I just gotta see them now."

She closed her eyes without saying anything so I took that as my green light.

I was still gently tugging on her shirt when she lifted up just the slightest little bit and I watched as that t-shirt was dragged upwards till the bottom of her big tits came into view.

All I could think was 'Fuck, this is so fucking naughty'.

At that point I reached down and cupped both hands up around the bottom of those tits, squeezing and massaging as I did.

Her shirt fell back down over my hands that were pressing her tits together with my thumbs now directly on her hard, warm nipples.

I wanted to see them but not as much as I wanted to continue feeling them. Fuck, I was horny.

She began to straighten her legs out underneath me pushing her feet from under that blanket in the process.

I moved around giving her room not wanting to spoil the moment. She ended up with her legs straight out and her head layed back on the armrest.

I was now straddled above her thighs on my knees with the inside of my thighs just touching the outside of hers and I've still got my hands squeezing her tits with her nipples now as hard as my cock.

She still had her eyes closed as she kept lightly chewing her bottom lip. Her blanket was now only covering her waist with her stomach showing above it and most of her thighs down below.

My dick was so throbbing hard I thought I could cum any minute.

My hips started to gently gyrate like I was fucking. I honestly couldn't stop it. I was so fucking horny my body was trying to fuck all by itself.

I glanced down thinking there's no way she can't feel this and I see her now looking up at me.

My body is still doing the 'fuck' motion as my cock comes poking thru the hole in my boxers. I don't think she can see it with the way I'm bent over massaging her tits.

At this point I don't care. I straighten up and my cock stands straight up above her tits while her shirt hangs right at the top of her big, smooth, hard nipples. Fuck me, I'm going to hell and I don't care.

I grab the base of my cock with my left hand and my right hand naturally wraps around the shaft and I squeeze it hard.

The head is so swollen it looks like it will explode.

Meagan looks at my hard dick. My married sister sees my throbbing hard dick!! I never would have ever thought this would happen, ever.

At this point nothing matters to me. I'm on autopilot. My left hand still holds the base of my cock as my right starts stroking up and down.

I can't control any of this, it's like I'm just watching someone else do it and my cock was harder and bigger than I'd ever seen it.

I take my cock and aim it downwards, pointing it at my sister's big, tan tits.

I hear Meagan now gently but urgently say "Michael, Michael we need to stop."

But I don't, I can't. I touch the head of my cock to one nipple, then the other.

I spank my dick on her tits. I keep doing that. I'm about to cum but I want one more thing before I do.

I scoot down a little and lean over her putting my left arm supporting my weight on the armrest of the couch right by her head and smash my cock between her tits.

The whole thing from my balls up to the head squeezed down between those perfect fucking tits.

I then take my right hand and put it beside my other on the arm of the couch.

Now I'm slowly fucking my dick back and forth between her tits. It's not really sliding, just squashing back and forth.

I hear her again now quietly say "Michael, seriously, we need to stop".

Still, I can't. It feels too naughty, too taboo, too 'something I should not be doing' and that's what seems to get me going.

My right hand slides over and cups the back of her head which is now underneath my chest.

I hunch forward as I pull her head upwards. I just hold her head as my body, seemingly on it's own, keeps making those fuck motions squashing my cock between her tits.

I keep doing this for a minute or so while her hands are on my thighs trying to hold me back.

Then something happens. Something wet touches the head of my dick. Oh god, it feels so good.

I hunch forward and feel it again and again. Damn, it feels good. Every time I push forward I feel it.

Could it be? Now I know. As I push forward again and feel a warm wetness surround my cock head.

Fuck. It's going between my sister's lips! Every time I go forward it goes a little deeper. Oh Fuck, I'm gonna cum.

I begin to fuck her mouth at this point. I raise up as I still hold her head but now its not a struggle anymore.

Her hands move up to my hips as my cock is slowly going in and out of her delicious looking lips. Her tongue is poking out under my cock now licking the head when I back out a little. Motherfucker, my sister is sucking my cock!

This goes on for about a minute. I then reach back and start rubbing her thighs. I drag my hand up between them until I cup her pussy hiding under that blanket and panties.

She moans around my dick when I did that and her legs spread just a little. I cup it again a little more firmly. Again she moans around my dick and she's enthusiastically sucking my cock now with her hands gripping my hips.

I press my palm down on her fabric covered pussy and rub up and down a few times. She begins grinding up against my hand. I go down farther to the bottom of the blanket and pull that blanket up till my finger tips bump into her wet panties.

She moans on my cock again. Fuck, her pussy is hot under those panties. I rub my middle fingers firmly into those wet panties, feeling her pussy squish inward as I do.

Again my body goes on autopilot. I pull my cock from her mouth and get down between her thighs.

She whispers "No" as I mash my dick sticking out of my boxers right onto her panty covered pussy. I start grinding it up and down like that.

Meagan puts her palms on my chest like she's gonna push me off but, she never pushes.

Meanwhile, I'm grinding onto her pussy slowly but firmly pressing downward and holding there for a second each time I do. I begin to go faster, getting a small gap between us and banging back onto her.

You could hear us bumping. You could hear my hard cock banging against her pussy. She was meeting my thrusts now. Her knees were raised up with her thighs splayed out.

I slowed a bit and started grinding a little more. I reached down and put my hand on her right thigh, sliding it upward till I touched her pussy. It was almost like the panties weren't even there it was so wet.

I hooked my fingers under the edge and pulled those panties to the side. Immediately my fingers went to her hot pussy, rubbing it up and down.

I found her clit and payed close attention to it as she started grinding into my hand. I grabbed my cock and rubbed the head up and down her lips a few times then pushed my whole throbbing, hard cock into her pussy in one quick stroke.

I held it there as I kissed her neck and felt her feet on my ass and her hands on my back.

I wasn't gonna last. I was practically already there.

I fucked my adult married sister hard, as hard and fast as I could. Banging her pussy like I was trying to push her thru that couch.

I reached under her, grabbed a handful of hair tilting her head back and fucked her harder than I've ever done anything in my whole life.

I fucked her till I came, pushing my cock as far in her as it would go when I did. I really don't know if she came or not as I was in my own world there for a moment.

After a minute or so I raised up making my still hard dick spring up from her pussy, slinging cum in the air as it did.

I stood up and looked down at my sister with the blanket still covering her above the waist. Her shirt above her tits, and panties pulled to the side of her very nice, smooth, well fucked pussy.

She looked up at me with my cock sticking out dripping cum on the floor and whispered "Where the fuck did all that come from?"

"I'm sorry" came my reply "Those big tits do that to me I guess."

As I looked back down I realized her hands had gone to her pussy and were rubbing as her ass was still subtly going up and down. I grabbed my cum dripping dick and began stroking it as I stood with it sticking out over her.

My cock was so slick with cum as my hand slowly stroked it. After a minute of this I knew I was gonna cum again.

By now I had grabbed the base of my dick with my left hand and squeezed as my right hand was stroking my cock as fast as I could.

You could hear the squelching sound of it as I did.

I couldn't resist. I got back between her legs and leaned over her and rubbed my cockhead up and down her pussy.

Her fingers were still busy playing with it and she didn't stop as I rubbed my cock around in a combination of wet pussy and fingers.

Slowly her fingers began to explore my dick, going up onto the shaft and squeezing some here and there.

I could feel her wet hand wrap itself around my hard cock as she was now stroking my dick while rubbing the head up and down against her lips and fingers.

Her other hand began spreading her pussy open as she did this. I gave a little push and with her help my dick started working itself back into her cum filled pussy.

This was so fucking nasty but felt so good. This was my sister! We should not be doing anything like this at all. She is married. I am married and my hard cock is slowly sinking back into her already well fucked pussy!

I feel a hand on my ass, then another as she has now started pulling me into her as she was pushing up to smash our crotches together with my dick as deep as it could go.I obliged her and began to fuck her again, grinding around in a circle when I went all the way in.

She had her knees all the way back with the bottom of her thighs facing up at me now, her pussy squashed up and puffy looking as my cock went in and out.

Fuck, it was hot to see. I began to pop it hard all the way in and out, then hold it for a second. I would stay poised above her with just the head of my cock in her pussy. Bang it hard and fast in and out then pause. Again and again.

At that point I heard her whisper "Yes".

I raised up on my knees, put my hands on the bottom of her thighs pushing her legs back even more and stated pounding that pussy that was squeezed up and presented to me to do with as I pleased.

Fucking her with complete control as this time, I think we both understood, it was about her.

I would fuck her pussy for several strokes, then pull it out and spank the head on her clit a few times, then plunge it back in and fuck her hard.

At one point I pulled out and pressed my cock onto the front of her pussy, grinding it between her lips with the head of my dick going up past her clit sticking over her stomach while I smashed my balls against her spread pussy.

I did that a few times then buried it back in her as far and deep as it would go.

By now I was pounding her hard and not stopping till she grabbed onto me, squeezing me as she bucked uncontrollably underneath me. Her mouth was pressed into my shoulder making an "Uh uh uh uh" noise.

That did it for me. I almost blacked out as I came in her pussy again. I guess I didn't realize how hard I was fucking her and my normal married sex is no where near the workout my dick just forced me through.

I held us like that till I felt her start to relax a little. I raised up with my dick still in her and pumped it once more, then as I pulled out I whispered "Did that feel good?"

She grabbed her shirt pulling it down over her pussy while looking back towards the kitchen and bedroom doors for a second and then back to me as she whispered "Maybe" with a little smile.

I turned and headed towards the shower wondering where this would lead and thankful we didn't get caught.I quietly open the bedroom door and find my wife is still snoring in bed. I tiptoe into the bathroom and start up the shower. With the warm water washing over me, my mind cannot let go of what just happened out on that couch...with my married sister!

I try to blame it all on her big tits, but there's more to it than that, so much more. Meagan has those kind of curves that make a guy think about sex. Her big tits seem to be what gets the attention, but upon closer inspection, her thighs and ass just dare you to try to look away. I also now know it's more than just an image, my grown up, married sister likes to fuck. It might've been the furthest thought from her mind initially, and I'm certain neither of us 'planned' what just happened...but she came on my cock. My grown, married sister grabbed my ass and pulled my cock into her as she no doubt came on her brother's cock. Fuck.

All of this 'reflecting' is having a very profound effect on me physically, my cock is, once again, as hard as it was a few minutes ago in my sister's pussy. It's probably going to do this from now on anytime the slightest remembrance of her creeps into my mind. Dammit, this is messed up.

The bathroom door opens and pulls me out of my naughty thoughts. I see through the fog of the shower--to which I have no real account of how long has been going--my wife heading towards the toilet. Shit, I can't let her see my soaped up, throbbing cock that I didn't even realize I was stroking!

I quickly turn facing away from her, and try to appear as if I am in the middle of the most normal, ordinary, boring shower I'd ever taken...hoping she doesn't want to join me.

Karen mumbles something about me being up early as she finishes up her business. I mention I wanted to get the most out of my time here. I know, lame.

She tells me she isn't ready for it yet, and heads back to bed. Thank god for last night's margaritas.

Once the bathroom door is closed again, I notice I'm no longer ready to launch a missile as it were, but still sporting a bit of 'excitement' that has a flattering effect on my 'physique.' Honestly, given the circumstances, I think it won't go completely soft till I'm back home.

I finish up, throw on a shirt and some lightweight cargo shorts--commando as it just seems to compliment the mood I'm in. I look down at my half asleep wife as I finish getting dressed. The way she is facing me on her side, her mouth--with her lips pouted together as she is slipping into dreamland--is almost perfectly level with the lump of my half hard dick in my shorts. I think 'why not' as I undo my shorts and pull my cock out. Just the idea of this, compounded by what happened earlier with my sister, has my cock rising to the occasion...any occasion it seems.

I grab it around the base and step forward. Karen is almost to the point of snoring as I touch the head of my cock to her lips, slowly rubbing it around. Damn, it feels good. I push against her lips trying to get the head between them. She starts moving a bit, no doubt waking up to my dick. I reach out and grab the back of her head as I push harder. Karen's lips open around my cockhead, a little dry at first, but once in and out a time or two, extremely slippery. She makes an almost irritated "Mmh" noise, but lets me slide my dick farther into her mouth, and even gets her tongue in the action as well...trying to lick around my swollen cockhead as I get more forceful.

I stand there beside the bed and fuck my wife's mouth. Any other time this would've been so 'normal' that I wouldn't have thought much about it. But now, all I can think is how utterly naughty it is that this same cock--my cock-- was in another mouth and pussy not even thirty minutes ago...and those belonging to my sister! Fuck, my cock is so damned hard again. I'm almost concerned Karen will wonder what has me so worked up, which reminds me of earlier events.

I get lost in the recent memory while fucking my wife's mouth and the next thing I know I feel her hands slapping at me and I've got both my hands on the back of her head and her lips smashed all the way down to my balls as I unload in her throat...I guess it was her throat, I honestly couldn't have told you where it was right then.

I let go of my wife's head as she pushes her mouth back off my cock. Tears are running down her face and she is coughing, trying to catch her breath while wiping the back of her hand across her mouth--a mixture of spit and cum dripping down on the bed.

"What the fuck?" She snarls at me, while looking from my throbbing cock still dripping cum, up to my face, and back again to my cock.

"I was horny," I tell her, "So I stuck it in your mouth."

"More like down my throat," she replies, "That fucking hurt," she adds while turning over away from me and pulling the covers over her shoulder.

"Sorry," Is all I can come up with, she doesn't say anything else. I wipe my dick on a towel from my shower, tuck it into my shorts--it still hasn't gone completely down--and head for the bedroom door, on the other side of which I have no idea what awaits.

The living room is empty. It is still early, but judging by the view out towards the beach, the sun will begin to rise any minute. I can only guess at the awkwardness of this whole 'situation' once I see Meagan again. For all I know, she's hiding out in their room, reluctant to come out because of me. My relationship with my sister never to be the same again.

Or, maybe it didn't have quite the same effect on her as it did me, and she has all but forgotten about it. Perhaps it would be best if I headed down to the beach, give her 'space.'

Once out on the beach, I begin to walk east towards the sun rising. There are a few people out, tourists like myself, and everyone is friendly with a nice 'Good morning' greeting.

The sun is about halfway up when I see her walking towards me, my sister Meagan. I'm once again struck by just how 'fuckable' she is built. I'm also reminded of the fact that we did in fact, fuck...about an hour ago.

I have no idea what her attitude will be towards me, so I approach her with caution, ready for whatever she might have to say.

I slow my walk as we near each other, she does the same.

"Hey," I say as nicely as I can once we are about six feet apart. I can only guess what her reaction will be as this is definitely uncharted territory between us. Hell, we didn't even keep up with each other much as it was, but now with this elephant in the room...I really don't know what to expect.

"Hey," she replies, in a tone that suggests she is not sure about anything herself.

"I thought you were still up in the condo," I tell her, adding, "I figured you'd want a little distance for awhile." The last part both playing nice, and feeling out the situation and perhaps her attitude now. I'm not lying when I say that I had alot riding on her response.

"No, it's fine...your fine," she answers in a nicer tone than I expected. A far cry from the mood of the wife I just left in bed a bit ago.

"Are you ok?" I ask. Knowing full well this is where the rubber is going to meet the road. If she's got any grief about what happened earlier, this is the question to get the answer.

"Yeah, I'm ok," Meagan replies as she reaches her right hand behind her head like she's scratching it...but it also evokes the image of a person in thought.

"We both know that shouldn't have happened, things went way too far back there," She states as she now puts both arms straight down with her hands claped together in front her, like she's trying to hide her sex in what I now see her to be wearing...snug fitting silky shorts with slits up each side. The added benefit of her arms and hands in that manner has the naughty affect of squeezing her big tits together in what almost appears to be only a t-shirt. Dammit, it's as if there's nothing she can do to not be sexy...if she doesn't want what happened earlier to happen again...she shouldn't be dressing like that because all I can think about now--is fucking her again.

Honestly though, it's like she's oblivious to what I see. I'm sure, given the timing of everything--especially since she was ahead of me--she merely threw some clothes on and headed straight down here to the beach. Which means one very naughty thought: my cum is still in her. My sister--my married sister--still has my cum in her pussy. Fuck. Thinking that is going to make my cock hard again.

Looking into her eyes, as best I can, I tell her, "I apologize, I've never gotten carried away like that before. But, I've also never seen anything like those before either." I then add as humbly as I can while motioning downwards with my eyes but still maintaining eye contact, "I think those are partly to blame, but again, I do apologize." I then followed that up by telling her 'that' kind of activity doesn't really happen at my house anymore...not like that anyway.

Meagan gave a chuckle as she rolled her eyes, then turning her gaze out over the water, she says in barely more than a whisper, "I can say it doesn't happen like that at our house either." Her face finally turns back to me, her eyes following a second or two behind. I swear it appears she looks right into my soul, almost as if to show a vulnerability in her last statement. A reluctance to a truth given to me in a moment...never to be mentioned again. If she wasn't so damned sexy, I wouldn't get so drawn in.

"Well, do you want to go back and get some breakfast. or are you still going to walk some more?...I know I'm hungry myself," I ask Meagan, not having an inkling as to what she'll reply.

"I got some great sunrise pics, I could go for something to eat too," She answers in a normal 'I-didn't-fuck-my-brother-today' tone...like it was just any ol' day.

I turn around and we both start walking back towards the condo, of which we are only a few minutes away from...neither of us saying anything else on the way. I don't know what she was thinking, but having her next to me...with those slits going up the sides of her shorts and her big tits wobbling around in what I'm sure is only a t-shirt...I was reliving the whole sorted, nasty event from this morning all over in my mind.

I let her go up the stairs first. Ours is on the second floor, but even the first floor is one flight up from the beach...with the white sand covering the first couple of steps.

Two flights of stairs behind--and slightly below--Meagan's ass in those silky thin shorts that fit her like a second skin with the bottom of her ass cheeks showing had me ready to fuck right then and there. I was hard in my shorts and if I went inside like this, our spouses were going to see it.

Once we reached our balcony, I told Meagan I would be a few minutes as I wanted to soak in the view some more. I walked to the outer railing and she went inside.

A few minutes later I hear the sliding door open and turn to see my wife, still in her pajamas, coming out. I just stay where I am looking out over the Gulf, watching the waves roll up on the beach. Karen comes to stand next to me, cup of coffee in hand as she too looks out at the waves. I remain quiet and a minute or two later she says she's going down on the beach. I watch as she makes her way down the stairs, and heads out on the sand. With my cock subsided, I head inside to see what we're going to do for breakfast.

The kitchen and living area are empty and quiet, but I hear a shower going in the background. I'm guessing it's Meagan or her husband, or perhaps both...who knows. Lost in thought, I open the fridge out of habit. Empty cold shelves remind me of my location...this isn't 'my' fridge.

Suddenly Paul comes out of their room and tells me he's got to make a run to an Office Depot for flash drives he needs for work. According to my wife, who keeps up with family better than me, he's the type that stays busy with calls and emails just about every day. He mentions that he'll be back in a few, and out the door he goes.

I walk over to the windows and look down on the beach. I scan around the various tourists, looking for Karen. She will usually take off walking for a little while when in locations like this.

I finally see her about three hotels away walking into the sun. As I stand watching, she continues to get farther away. The sound of the shower reminds me that can only be my sister under that water...with her big tits, thick thighs, hot a...there I go again. Damn. And there goes my dick again.

I can't help myself as I make my way towards their bedroom door. I'm involuntarily squeezing my cock through my shorts as I cut through the kitchen on my way. My mind will not let go of the image of my naked sister in that shower.

Thinking Paul will be awhile as he probably hasn't even got their car out of it's parking spot yet...and my wife is a ways down the beach taking pictures, I turn their doorknob before I realize I've even done it. I push the door open and listen to the sounds of my big-tittied sister in the shower...the same sister that came on my cock earlier today!

I can't help but wonder what that vision looks like right now and before I know it, I'm coming up to that partly opened bathroom door. Steam is drifting through the foot-wide gap between the door and frame. I look back towards their bedroom door and surprisingly realize I closed it behind me. It's like I'm watching a movie of my own perverted making...like observing what my irrational self is capable of doing if left unchecked.

I now turn my attention back to what lies on the otherside of the bathroom door...namely my naked, married sister. Poking my head into the gap of the unclosed door, I see through the steamy glass: skin...hips--thighs--and those big fucking titties. Her hands are rubbing soap all around, caressing around her neck, down her sides, coming back up to cup her tits and press them together...FUCK.

My cock is hard in my hand...my hand! When did I pull it out? Dammit, I swear there's a side of me I'm neither aware of, nor in control of.

I can't stop jacking my cock as I watch Meagan squeezing all around her soapy tits...those big nipples! Her left hand stays on her tits, cupping and lifting them up--one then the other--while her right hand goes down her side, over her hip, and around to grab her own asscheek. That same hand then glides its way around and down to cup her pussy. OMG!...she's doing more than just washing off this morning's fuck adventure...the adventure she had with the very same hard cock that I'm currently stroking. Meagan--my married sister--is masturbating! Fuck, this is hot. I know we fucked earlier, but that could almost be construed as a coersion on my part.. a slight forcing of the circumstances. This...this is her getting off all on her own, by her own doings, and coming from her own naughty thoughts. Which, by the way, had me thinking now...what's on HER mind? Some random guy, maybe a guy from work, or some moviestar?...or the fucking she got from her hard-dicked brother earlier on the couch while everyone else was still asleep.

I'm going to cum if I don't let go of my cock. Looking down, I see it flex and throb all by itself...strings of precum dripping from the head onto the floor. Looking back at my married, big-titted sister in the shower, I see she is now holding onto the top of the shower withone hand--eyes squeezed shut--and methodically rubbing her other hand, all four fingers, up and down her soapy pussy!

I'm right at the shower door before I realize I'd even fully entered the bathroom. I didn't hesitate as I slowly open the shower door. My dick is standing straight out in front of me, twitching and throbbing as my sister unknowingly continues to rub her now overly clean pussy just a foot and a half away from me.

I step right up to the edge of the shower opening now...my cock invading into the shower space by six or seven inches. Meagan is picking up the pace now, rubbing her pussy faster. Me? I dare not touch my cock or I'd cum in a second.

Without thinking I reach up and cup one of her big fucking titties. That wakes her up! Meagan gets the biggest surprised look I've ever seen on anyone...especially when she sees WHO it is (I'm sure she initially assumed it was her husband Paul)...and what I have sticking out from under my shirt...her brother's throbbing cock.

I can tell by the way she tucks her thighs together that she, once again, isn't morally on board with this new turn of events, but just the same, she doesn't stop my hand on her tit...even as I start to flick my thumb across her big, hard, wet nipple.

Meagan's face is pointed downwards, almost like she's embarrased at being caught having fun, as I reach with my other hand and grab her hip, pulling her closer to the door opening. That hand now runs around and squeezes her asscheek, so slippery and sexy.

She still has a hand on her pussy, covering or caressing it, I can't be sure. I take my now wet hand off her tit and grab my hard cock with it. I jack it a few times, then put that hand around on her other asscheek, pulling her wet, naked body towards me and bumping my dick into the hand she still has on her pussy.

With the shower being a few inches higher than the floor, it has the benefit of putting my cockhead at a better angle, if only her hand wasn't down there blocking things.

I grab my dick again and rub the head around against her hand covering that married pussy. I continue rubbing and pressing against her fingers in a silent plead for access while she bites her bottom lip with a pained look on her face as she looks towards the door.

I follow her gaze over to the door, then turn back to face her. "They're all gone right now," I say barely above a whisper." I keep rubbing around her fingers with my dick, occasionally touching skin in between those fingers.

"I'm so fucking turned on right now," I tell her, hoping for something more, but knowing time is ticking. I take my cock by the base and vigorously shake it up and down a couple times...banging her hand covering her pussy, in the process.

She still has a grip on top of the shower with one hand, while her other hand is preventing her brother from fucking her married pussy again...right there in the shower.

"This is fucking crazy," Meagan says a little louder than I am comfortable with given the circumstances... making me feel like she might be coming to her senses and wanting to put a shutdown to this fucked-up brother/sister shower thing.

"Come on, you know my hard dick will feel better than your fingers," I plead in a hushed tone, hoping she hasn't come down from the obviously horny state she was in when I came in here. "All you gotta do is move them and I promise I'll make you feel good...or I'm going to end up cumming on those fingers because I'm about to pop." That last part added matter-of-factly.

The sound of the shower was almost deafening as I searched Meagan's face for an answer. She turned her face downward again as I feel her fingers begin to caress around the head of my cock, and onto the shaft...gently squeezing and pulling.

She keeps the one hand still holding the shower, while her other hand works my cock into the proper angle for penetration. Holy shit...we're going to fuck again! I can't wait, I know if this doesn't happen right this second, Meagan may change her mind.

I grab my dick and almost violently curve it upwards while bending my knees slightly to lower my body. My cockhead squeezes into my married, adult sister's wet pussy again. The angle is tough to achieve due to our height differences, but I'm not about to give up...I just bend my knees some more AND my dick--almost to the point of breaking it--which in turn gets a third of it into that slick, velvety pussy.

I let go of my cock and we both look down at it, forcing the angle so that it's sticking straight out of Meagan's pussy as opposed to sticking downward...the way nature originally intended.The side effect of this situation is that the sensitive part of my throbbing hard dick is being squeezed hard against the bottom of her pussy...conversely, the top of my cock is pulling tightly upwards between my sister's pussy lips, smashing her clit so hard that when I begin to pull back slightly, it pokes out from under it's hood...dragging along the top of my dick.

I waste no time in trying to get an 'in-and-out' rythm going. With this extreme angle of attack, it's overly sensitive on my cock...and given the way Meagan's knees are almost buckling...I'd say it feels good to her as well.

I keep doing that...in-out, in-out...each time pushing a bit deeper when it goes in. After a half dozen strokes, our pelvises bump...I've got my married cock buried in my sister's married pussy. No pussy has ever felt like this in my life. Fuck me, it's so damn tight fucking while standing like this.

I've got both hands on her ass now, pulling her against me each time we bump together. Fucking has never felt so good. If you've never fucked standing up, you should give a try if at all possible.

The intense angle is making it too extreme for me. Every millimeter of movement in my sister's pussy has me literally about to blackout. It's too much, I'm going to pop any second. I know I told Meagan I would make her feel good, and those were my intentions...but I'm going to cum so hard in the next two or three strokes that I'm certain I'll let her down.

Just when I thought I can't hold on any longer, Meagan begins to go all herky-jerky, knees buckling, head rolling back...until she loses her grip on the top of the shower and falls to the shower floor in a heap! My cock popped out of her pussy right as I began to cum...squirting out of my dick onto my sister...once, twice, three times. Fucking hell! I can't stop. I grab my cock and finish stroking it as the shower continues to wash over my sister.

I get my bearings back a few seconds later and immediately reach in and turn off the shower. Meagan looks up at me from the shower floor. My cock is still sticking out, almost right over her face at this point.

"Are you ok?" I ask, hoping she is. She just looks me in the eyes, down to my still hard cock, and back to my eyes...then smirks. I try to help her up as best I can as the shower is slippery. Getting to her feet she steps out of the shower, sits on the closed toilet, and grabs a towel. Looking up at me as she wraps the towel around her shoulders, she looks up at me and silently mouths the words, "Put that away and get out of here."

Her actions make me take into account my surroundings--I'd all but forgot where I was--and that my dick is indeed still out.

Quickly making myself presentable again I lean down and whisper, "Are you ok?"

To which she gives a slight laugh while looking over towards the shower, then looks back at me and replies in a whisper, "Yes, now go."

I open their bathroom door and see the bedroom door is still closed. I make my way over to it, and as scared as a kid checking for monsters under a bed, I slowly open that bedroom door. My heart is pounding because I have no idea if my wife is out there...or Paul. I can only guess Paul would've at least came into the bedroom upon returning...but my wife, I can only hope she's still down at the beach.

I walk out into the kitchen area...and there sits Karen on the couch...with her coffee and her phone. She looks up when she hears me.

"Where were you?" she asks me....
