I've been a longtime fan of this community but this is my first post ever on here. In my mind, there are about 4-5 stories I've wanted to write up and post on here but just could never find the time to do so. We've recently had one amazing encounter though that in some ways made me think back of how far me and my wife have come in our sexual history. I felt like this would be a good time to recount some of the events leading up to now.

So with that, here it goes. This first event happened around 3 years ago, pre-covid. I feel like this is a super long story, with lots of background info. If you are here just for the fun stuff, scroll on to the ****** below

Firstly, let me describe a little about myself and my wife. At the time of this story I'm 37 and my wife is 36. We have been married for 7 years and have been together for over 10. I'm asian, just shy of 6 ft 165ish lbs and fairly fit. Staying healthy and going to the gym has always been important to me (had some health issues in my teen years that opened up my eyes a little bit). Definitely not packing anything crazy below the belt, very average 5.5", maybe 6" on a good day. As for my wife (this story is actually about her sister, but we'll get into her later on), she is also asian, 5ft4 and around 105lbs. Smaller boobs, perfect handfuls I would often say. Definitely more "cute girl next door" then "bombshell sexy". I wouldn't classify her as incredibly fit but also no where near overweight. She has never been a fan of going to the gym or working out but has always seem to not gain any weight, despite all the snacking she loves to do.

As for our sex life, I would say its fairly plain and vanilla. Both myself and my wife have only had 2 partners each in our lifetime (one each before we met). So neither of us were exceptionally experienced when we first met. But don't get me wrong, we were going at it like rabbits in the early years. Any chance we got, we would sneak off or hang back and find some alone time together. But in terms of experimenting or doing things a little more risque, it has always been more of a dream then a reality. I have always had a super high sex drive, while my wife is more on the medium to low end. But with that being said, we've always been happy with where we were in life. Obviously there was always the thought of trying/experimenting more sexually, but it seemed both of us never really knew how to get started. This story will kind of lead us through the start of our so called "Sexual Awakening".

On to the vacation!

Me and my wife love going to Maui for vacations. Something about the warm sun and being by the water. This was the first place we ever travelled to together and we have returned back every couple of years for a nice getaway. This time around, we decided that we would plan a trip with my wifes sister and family (husband and two kids). Well, actually my wife and her sister planned the trip and I was the loving husband that said fine, we can all go together. In my head, I already knew this meant very little time for me and my wife to hang out alone and a lot of "helping out" watching the kids. The good thing though was that I actually enjoyed looking after and playing with the kids. And on top of that, I was able to convince my wife to book an extra 2 nights longer on top of our trip just so that we can still have some "us" time. This was monumental as there is another story of the end of this trip that I would need to share with you all as part 2.

We booked a nice big house in Kihei for our stay. Super fancy and something we would not normally book just for ourselves. The first couple of days were pretty standard, lots of beach time, eating out, and hanging out in very family friendly areas. My sister in law (gonna call her Jen) and her family are big foodies, so they like to go out and find the coolest and most interesting places to eat. We ended up at this seafood place on night number two. The food was pretty good, very asian-hawaiian fusion. The next morning rolls around, and I wake up to multiple toilets flushing and crying and puking noise throughout the house. Still to this day we all have no idea what was the cause of all of this, but my wife, Jen's husband and the two kids were all puking there brains out. We don't think it was food poisoning but maybe a small bout of stomach flu, who knows. But day 3 was basically me and Jen making trips to the super market picking up medicine and helping clean/sanitize the house and taking care of the kids. Great way to spend your holidays!

Day 4 rolls around and it seems like my wife and Jen's husband were starting to turn the corner. The kids still had mild fevers but they're spirits were improving. Nothing like all the chicken soup and paw patrol you can handle to quickly distract kids from being sick or all the sunshine and playing outside at the beach. We were all hanging out in the living room, when Jen's husband suggests that me and Jen go out and salvage a bit of the holiday.

Matt (Jens husband)- "We're fine, me and Kate (my wife) can hang with the kids. You guys go out and get some sun"

Jen- "Are you sure? Its not a big deal for us to stay back"

Kate- "No you guys should go. We're just going to be here resting anyways. Just come back with more soup. Not chicken noodle pls"

Me and Jen looked over at each other, and decided that it would be nice to go out and catch some sun for a couple hours.

So with that, we packed up some beach stuff and we headed off. Now I have never really hung out with Jen before, let alone without my wife being there. Jen is 4 years older then Kate, so at the time of the story she was 40. At first glance, Jen and Kate look very similar. The running joke was that they could often pass off as twins. Jen however was a lot more active. She is a bit of a yoga enthusiast and loves running. In her younger years, apparently she did a bit of judo. Also roughly two or three months before the trip, I also found out she started doing a bit of weight training. That part of Jen always caught my attention, but besides that I've never really looked at her in a sexual way.

I loaded up the minivan (cruising in style, lol) and gave my wife a quick kiss goodbye. I heard the door of the van open and in hops Jen, wearing cutoff jean shorts and a fairly open-weaved top, just showing a hint of her bikini underneath and a little bit of midriff showing. I turned out of the driveway and asked her if there was a beach she wanted to check out.

Now I know which beach I wanted to go. A thing that me and my wife love to do when on vacation, is to try and track down all the nude beaches we can get to. There's just something about being out and naked in the open in an area where nobody knows you. Kate wasn't always this way though, as she has always been super conservative and a bit self conscious of her body. But an accidental nude beach encounter on one of our past trips and a lot of coaxing to join in on the fun ultimately changed her mind. Now, she's the one often suggesting we go and check certain nude beaches out on various trips. This was a major turn on for me, as I saw her start to become more confident with herself. I often joked that this was her turning over a new leaf as she starts to explore more of her sexual side. Little did I know that this was actually true!

******************************

So off we drove in around Kihei looking for a beach, when Jen suddenly breaks the silence and says

"hey so I read up that there's a nice beach not far away, in Walea. Maybe we can check that out"

"Yea sure, why not"

In my mind, I'm wondering.....hmm wonder if its the nude beach that me and my wife often go to haha

"So the beach is called Makena Beach, looks nice and there's a tiny beach off to the side called Little Beach"

"Oh yea, cool. Lets do it" I said

"O it looks like its a nude beach.......but that's ok right? Like you and Kate love to do that type of stuff?"

My mouth dropped to the floor.

"Uhhhh, what? Where did you hear about this??"

"Well, after your last trip to maui, Kate was showing me some pictures. And I guess she forgot to delete one or hide it, I don't know. But yea she was clearly topless. And I was like, did you guys go to a nude beach???? And then she said yea, they're fun"

"Wow, ok. I never knew my wife told you about that. Yea they're fun. A lot more relaxing then normal beaches cause there aren't any kids running around. And definitely not as many creepy old guys there than you would expect"

"Cool.......so you want to check it out? Like it won't be weird, will it?"

"I guess not, we're all adults here"

"Cool"

So off we went, a short 10-15 min drive away. We pulled up to the parking lot around 1130am. We could tell it was going to be a hot one, so we grabbed the sunshade and our towels and headed off. For those that are not familiar with Little Beach, its a short walk from the parking lot through Makena Beach, and then up and over a small rocky trail. We were pleasantly surprised that there wasn't a lot of people there, maybe 2-3 other couples and couple of singles. But all spaced far enough away from each other. Right away, I could tell Jen was excited but also a little taken back with everything. She had the biggest smile on her face but you can also tell she was out of her element.

"OMG, Like theres naked people here! Like there's a penis and boobs! OMG....wow, like some of them are good looking people too, not creepy guys at all.....Like I was picturing leathery old guys walking around hahaha" Jen joked quietly.

It was kind of cute and sincere to see Jen all flustered like that. Definitely a side of her I've never seen before. We decided to set up near the back of the beach, 3/4 of the way down. I got the sunshade set up and Jen laid out the towels.

"So do you just get naked? Like what does Kate do?"

"Well yea she usually scouts out the beach first and if there's other people around that are naked and no creepers around, then yea she usually goes for it"

"Wow, I would never pictured you guys doing stuff like this, especially Kate! Shes always been so reserved and shy growing up. K, i'm gonna do it. Wait bottoms too?"

"Yep...like its up to you, do what you're comfortable with. Kate usually takes her bottoms off, hops into the water then puts them back on when she gets back to her towel. You know, so that sand doesn't get everywhere haha"

"Wow, K. Wait you're getting naked too right??"

"I usually wait a bit, get settled and then join in when I hit the water"

"K you better. Alright here I go"

And just like that before I know it, off comes the weaved top.....off comes the bikini top.....off comes the jean shorts.....and off comes the bikini bottom. My sister in law is now completely naked standing in front of me. Again, my mouth drops to the ground and I am completely speechless. For someone who has had two kids and is 40 years old, Jen looked absolutely AMAZING. You could definitely tell she worked out, just the slightest hint of a 4-pack, everything tight and toned, B-cup boobs slightly bigger then my wifes (probably from having the kids), and completely shaved down below. Instantly I could feel blood rushing to my cock, thankfully I was seated down on my towel.

We sat there for a bit and just people watched. Jen asked if I wanted to go into the water, but I felt like I still needed to lay down on my towel for a bit longer haha. She stood up and trotted out towards the ocean, her tight little butt cheeks giving just the slightest jiggle as she made her way down. I grabbed some water to drink and closed my eyes, trying to calm myself. It worked perfectly. Hard on went down but now I was sporting a nice partial chub between my legs. Sweet lol, that was a close one. After 5 or so minutes, Jen came back. Water glistening from her perfectly toned body, small droplets running of her breast and over her small perky, hard nipples. She toweled off, reapplied some of her sunscreen (thankfully she didn't ask for help) and laid down on her towel beside me face down. Surprisingly, she left her bikini bottoms off. Looking over, I could just see a glimpse of her pussy lips. O man, this is dangerous...I can't be doing this. I turned and looked forward, took a deep breath and closed my eyes to take in the hot sun.

"You should jump into the water, its so refreshing!"

Hmm she keeps suggesting I go in.....

"K yea sounds good"

One quick swoop, I drop my shorts and ran out into the water. It actually was super refreshing. I could instantly feel all of the knots in my back and stresses floating away. I swam around for probably 10 mins or so. Alright, time to head back to the towel. I got out of the water still sporting a nice partially -hard, dangling cock (probably the mixture of going back up to see Jen and the cold ocean water). I was actually quite impressed if I do say so myself. As I got closer to our sunshade, I noticed Jen was now turned over, half lying on her back half resting on her elbows looking forward. My god she looked amazing right there, her perfect boobs resting on her slender tanned and toned figure. She had her sunglasses on but I could tell she was looking right at me as I walked up.

"How was it?"

"Soooo goooodd"

We both tried to play it cool, she kept looking forward but I could see she kept trying to steal glances over at me. I toweled off and laid right beside her, suddenly calmed and confident. We made some small talk about work back home and the kids. This helped bring me back to reality a bit.

"So....this isn't weird right?" I asked

"Weird? What, no hahahaha" Jen laughed nervously as she continued staring straight ahead, "I mean we are just two grown adults hanging out at the beach. Like yea we're naked and all but that's fine. We both take care of ourselves and look alright I think right? Like...good for you, you look pretty impressive...uhmm down there, o god"

Jens face instantly turns a dark shade of red as she realized exactly what she just said.

I gave a chuckle as I felt my cock slightly twitch a little.

"We're all adults here" I said. "And you're looking pretty good yourself, I can see the weight training is working!"

"O really? Yea I guess I've been going pretty hard lately in the gym. Its actually kind of nice some one is noticing"

"What you serious? You look hot, I wish Kate was more active like you" (I'm a horrible husband *palm to face*)

"Yea Matt hasn't really noticed....or said anything"

"Well, Matts not the most observant guy out there haha, like I swear always forgetting where he left his glasses and keys"

"Yea I guess, thanks"

Sweet, in the clear. We both laid back down on our towels to catch some sun. I closed my eyes for just a second and then I hear

"uhh, hey can you help me with some sunscreen?"

"yea sure"

We both sat up, Jen facing the ocean. I made my way around her and starting working the lotion onto her shoulders and back.

"hmmm Kate did say you give great massages"

"O yea...."

I start working my way down and around her back and along her sides, getting awfully close to the sides of her breasts. Lower and lower, I got to just above her butt. I paused for just the briefest second, then almost on queue she slowly leaned forward into doggy position, giving me a nice, long look at her surprisingly glistening pussy and then down onto her stomach.

"You may continue" she joked

I took a deep breath, moved forward and started applying sunscreen on her butt and legs. As I worked the butt, I kept getting glimpse of her asshole and pussy each time I worked her cheeks up and around. Her beautiful, plump pussy lips were definitely showing signs of wetness.

"There you go, all set"

"Thanks!" as Jen sat up and turn around. "O wow, OMG"

Her eyes quickly shot up with her hands covering her mouth.

Without even knowing, I somehow went from partial chub to full on, totally engorged, raging boner. There was no hiding it, absolute full mast. Like how I said at the beginning I'm fairly average below the belt. But at this one particular moment, I felt like I was about to explode. Like my cock was nearing pornstar mode and reaching out for the sun. I looked down and quickly tried to cover up with my hand.

"Uhhhhhh sooo sorry, this is bad. And so wrong."

"Nono, like I said.....Bravo!" Jen laughed with the biggest smile now on her face, and her eyes fixated on my poorly hidden cock. "Don't worry about it, its normal. And its kind of my fault...like who asks someone to help put sunscreen on there naked sister in law" she laughed.

"Haha yea for sure. Anyways, I gotta sit down, just give it a sec, it'll go down."

We both sat down on our towels, silent for what felt like hours...it was really only like a couple minutes.

"Well I kind of feel bad....cause like I caused that." Jen said softly....."Is there anything I can do to help?Like....Do you want....a hand?"

Now I probably had the stupidest face ever as I looked both totally confused and aroused.

"Here lay back" she motion me to get farther into the sunshade. "Nothing sexual.....just helping out my brother in law, anddddd his incredibly large penis"

Jen looked side to side to double check that no one was around and could see into our sunshade. She started getting close, placing one hand on my chest so that I would lay farther back. She then licked her fingers and placed them on the head of my cock, slowly working down the shaft and then back up. Each time she got to the head, she would do this half turn with her fingers and then back on down. I was in heaven.

"WOW....seriously I had no idea you had such a big penis. Like the girth on this thing haha, its like the size of my wrist! You are soooo much bigger then Matts!"

"uhhh thanks" I said as I was drifting in and out of pure bliss

"Yea you like that, you like my soft hands stroking your big massive cock?"

"yes...o yes" O god, dirty talk.......

"Yea, you like how your massive cock could stretch out my tight pussy?"

"uh....yes?"

"Yea, you want to fill me up, right here out in the open on this beach"

I open my eyes, there Jen was, naked, biting her lips, kneeling beside me, one hand stroking my cock, the other hand squeezing her breasts.

In a brief snap of clarity, I grabbed her hands to stop. "Oh man this is too much, we can't be doing this"

The next thing she did was one of the most sexiest things I've ever seen. She looked me deep in the eyes, and slowly said

"K, this is happening. We're going to fuck and theres nothing you can do about it. I haven't had sex in a very very long time. I need that cock inside me now"

Quickly Jen looked side to side out of the sunshade to do another double check, then she bent down and shoved my rock hard cock into her mouth. At this point I have lost all control. She started working it up and down, with both hands, working my shaft and my balls. I have no idea how I didn't explode right there on the spot. She went at it for probably 4-5 minutes, then she stopped. She then crawled up beside me and laid against me, her back resting against my chest. My throbbing cock riding right up her ass crack. She reached back and slowly guided me into her pussy from behind. I used my right arm to reach over and grabbed her breast, using the inside of my fingers to twist and caress her nipples. She started moaning softly, but every time I thrusted forward, she would let out the faintest whimper. I couldn't believe how tight, yet how wet she was. It felt amazing, like I could feel every part of her every time I went in and out. She reached over with her hand to grab mine, I could feel her start to tense up and her breathing was getting super fast.

"Oh god, don't stop, i'm gonna cum soon"

"Me too"

"Cum in me, its ok, i'm on the pill"

Another minute of intense thrusting, and then I could feel her legs start to shake violently. The thought of her intense orgasm sent me over the edge. I must have shot 10-12 ropes into her. It was probably still to this day one of the craziest, most intense orgasm I have had in my life. Her body went completely limp as I held her in my arms. We laid still for 5-10 mins, Jen still resting in my arms trying to catch her breath. I could start to feel my cock slowly returning back to its normal state, cum slowly gooing out of Jens pulsing pussy.

"Wow....you have no idea how much I needed that" she softly said. "Don't worry, this stays on the beach. I won't tell anyone"

We collected ourselves, got cleaned up and hung around for another couple of hours. A couple more dips into the ocean and a couple more teases touching each other in the sunshade and then we packed up and headed home. Jen threw on her bikini bottom and her shorts and then just her weaved top on. You can clearly see her nipples poking through.

"O wow, that's daring"

"Haha, yea I know right. I guess you just bring out the wild side in me. Don't worry I'll throw my bikini back on before we get back"

We both laughed and made our way back to house, like nothing ever happened.

Kate- "Hey so how was it? Looks like you got a little sun there! You pick up the soup?"

"Damn.....I knew I forgot something"
