So me and my sister in law stubbled upon that we're both in loving relationships. But both are bored sexually. Well we were.
As the conversation deepened and the booze took over more we started to confess we had kinks and desires that our respective partners had either declined or at risk of getting nothing sexually we didnt confess to.

We had always got on. But id never really looked at my wifes sister in that way before our drunken stroll home after an unplanned piss up.

Angie was intrigued by my honesty about my watersports fetish omission.
Asking had i experienced. I had, a few years before meeting her sister. Ill admit it was more of an accidental thing as i was fuckin a girl and had cum inside her. She and i loved her pushing it out and have me clean her cream pie. But on this occasion as she squatted and pushed the hot cum from her dripping freshly fucked c**t hole, i was hit in the forehead by a stream of piss. The cum followed and dripped onto my tongue.
Abby, the woman in question, stood up in and as i looked up was clearly embarrassed. Apologising profusly. However i laughed and said pee is sterile and i still wanted to clean her cum filled pussy. She hesitated but eventually assumed her position. As she squatted she spread her lips and pushed again. The cum came tumbling out, and as i licked it up i felt another splash of piss hit my face. Rather than waste it i cupped my mouth around her bald pussy and gulped down the cocktail of my cum and her pee. I had never been so turned on. I knew it was different from normal as i was now hard again.

After i had finished up telling Angie about my 1st encounter with piss, Angie smiled and said it sounded so hot and dirty. She could see how it would be sexy. Eventhough she had never thought of the thing she does everyday, could be used in a sexual way. She continued to question why i thought it was a turn on. With no regard to the fact i had never discussed this with her sister/my wife. I had already said i kept it to myself as Rach, my wife, had no interest in some normalish kinks like mutual anal and cum play.
As we knew we were nearing the villa Angie stopped and looked out to sea. It was dark, the only light from the street lights on the walkway next to the beach.
I asked why she had stopped.
"Its still to early yet" she said before adding. "Weve got 2 beers each left and no doubt a few stories to tell" as she turned and winked at me.
Angie then went on to tell me she had an affair 10 years back behind her husbands back. It was with one of her friends dads. She went on to say he was very experienced at eating pussy and fucking, with his big cock. He had taken her anal virginity and she explained how eventually she became his sub. They booked time away. Indulging in roleplay, bdsm, cum play and even swinging in their year long affair before he died in an accident. I could hear thst this upset her in her voice but she said that she had been falling for him and although she got over it she never felt guilt as her hubby was a selfish, boring lover. Hadnt always been but over the years had become lazy.
By now we had one beer each left. It was still only 12:30 and we had told my wife and her hubby we were doing karaoke and would be back soon. A legit excuse as we always did when away. We loved it so we never got any suspicion from either partner.

We chatted more about sex without caution or care, no regard for the fact we were revealing our inner most desires that we hadnt been able to tell our partners.
Angie started to fidget and wiggle about. As we talked more she stopped me mid sentence to tell me she needed to wee alittle hesitently. I smiled and said "well its dark and no ones around" also adding id look away. I did however cheeking joke "and i'll try my hardest not to get turned on".
Angies look of slight embarrassment turned into a cheeky smile. Her eyes stared into mine as she winked.
Now i'll admit, i had never looked at angie in a sexual way in the 9 years i had been with her sister. Not only because its wrong, but she wasnt as attractive physically as my wife.
Sure Angie had 2 kids but was far from fat. She just fell into the role of mum and housewife whilst also doing a part time job some evenings.
She mostly wore sweat tops or jumpers over t-shirts. Jeans or jogging bottoms. On rear special occassions she would put a skirt or dress on and a little make up, but you could see it wasnt her cup of tea.
However this was the first family holiday we were on. My wife my son, inlaws, Angie, hubby and two kids.
Angie is 6 years older than me or my wife too. This was the 1st time i saw Angie in her bathing suit. Bikini to tell the truth. Im not gonna lie. Im a red blooded make and always sneak a peak at women on sunny holidays.
This was no different. My wife knew that me seeing her in a bikini always got me turned on. Partly knowing she had shaved her pussy completely bald and all that seperated me from her smooth c**t was a piece of crotch cloth. However with her family being on holiday with us and our son in our room i had no chance of horny holiday sex. Rach used be a little more adventurous on previous hols. Different positions, all over the room/appartment, any time of the day. Even once sucking me off in a bar toilet. Ok its pretty straight forward and normal for this site but you know what holiday sex is like.
This time though i had been limited to an interupted handjob which never got finished. And she point blank refused to do anything as her parents might hear/ come back early.
Needless to say i was frustrated.

I digress. The 1st full day of the hol i saw Angie in her bikini. She walked past me as i plyed with my son in the pool. I noticed she had a major pear shaped figure.
She wasnt one for the gym of exercise and you could probably figure out she had kids. A few wobbly bits but nothing gross. She had smooth lightly tanned skin and the 1st thing my eyes were drawn to was her massive tits. Under those jumpers and tops she had hidden an ample bossom. The bikini top being only just big enough to keep in the slightly jiggling boobs.
I could clearly see her perky nipples pushing out the bikini top covering them. As she turned to lay her towel down on her lounger my eyes were drawn to her bikini bottoms. As she sorted her space out before apllying tanning oil she stood in a way i could see her bikini bottom crotch area being eaten by a clearly meaty pussy. Her thighs slightly chubby but her legs showing a nice curve.
I quickly snapped out of it and carried on. Later in the shower thinking she looked quite nice for a change.

So back to the beach. Angie and i stared at one another after my half joke half truth had come out.
Angie tonight was wearing some shorts with a vest top. My wife and her teen daughter had done her make up for her. Again ill admit i had perved down her top a few times earlier in the evening. See her mounds nestle in a black bra.
Angie got up slowly. As she did she started to undo the little belt on the shorts before undoing the button and zipper. She turned to face me and stood with her legs shoulder width apart. I knew what was to come. I just couldnt believe it. As she started to bend into a squat she pulled her shorts to just above her knees. She then pulled them up at the crotch as she got into full squat. With her holding her shorts slightly i could make out with the little light availible her fully shaven meaty pussy. Large lips slightly hanging down. She was balanced perfectly. She still looked at me with a devilish stare and a sassy smile. All of a sudden her free hand reached between her legs and parted her lovely lips.
She then softly spoke with a tone id not heard from her before.
"You can wank if you like. Ive always wanted to see this big cock Rach has bragged about" she purred.
Ok so without sounding arrogant ive been blessed with a 10inch cock. I workout, am quite tall and am not bad to look at. Thus pulling a stunner in my wife.
Anyway. I unzip my shorts, and as i go commando all the time, my cock sprang out. Angie gave a moan of delight as her eyes bulged slightly.
Breathing slightly heavily now as she squatted, displaying her spread pussy to me. Angie spoke again. "Play with that gorgeous cock for me" she asked me with her breating becoming heavier. "Pull that foreskin back, let me see the head" she added in a slightly authoritive way. I did as she asked. I pulled back on the skin cover to reveal my now leaking peehole and head of my swollen throbbing dick.
Angie let out a moan, muted slightly as she was aware we were in public still. I saw her manouver her fingers slightly. So her middle finger hovered over her exposed clit as the fingers either side still opened her pussy. As i continued to divide my staring between her pussy and face she then told me to stop playing with my cock and watch. I did as she asked. By now i was sure she was going to give me what i yearn.
There was a slight pause and her middle finger stopped moving seconds before a strong stream of piss shot from her twat. I was in ore as i could nearly see her hot piss cascade from her amazing pussy trickling a little between her arse cheeks. It wasnt long before she eventually slowed before stopping. Some pee slightly dripping from her lips.
She wiggled her butt a little to shake the excess wee from her. She remained squatting and looking at me with my hard cock pertruding from my shorts. By now the precum i create was dribbling down my cock and shaft.
Angie said i should not waste it. I knew what she meant. I quickly wiped the dribbles with my fingers before greedily stufging them in my mouth. My cum was slightly sweet tasting tonight. I was ready to explode.
Angie in the meantime had stood up and left her shorts hit the floor. She stepped out of them and parted her legs so i could get an even better view of her exposed pussy before she started to furioisly rub her clit. I began to pump away on my shaft. Both of us watching and enjoying this out of the blue fun.
The picture i have in my mind of my sister in law peeing for me and enjoying it after only finding out about my unconventional desire a few hours before, whilst the booze had tsken hold. By now i had sobered slightly. Not enough to realise, that although we hadnt touched or kissed, whst we was doing was the ultimate betrayal. There we were, my sis in law naked from the waist down. Stnding over me as i now lay on the sand, wanking my big cock.
Angies breathing got heavier, a few little moans with it before she told me she was going to cum. With thst she tensed before moaning loudly into the night air. Her groin thrusting back and forth. But i was in for another surprise. As her orgasm happened i noticed her pussy was streaming with every jolt. She was a squirter. I could feel the warm on my feet. She came to a pause before dropping to her knees.
I continued to wank as she gathered herself. She looked up and smiled with satisfaction. Still breathing heavily though. Eventually as she started again to watch me wank my dick she sat back on the heel of her feet. " i want you to stand up and wank over my tits" she said, again with a little authority. With that i stood. My shorts now falling to my ankles. As i stood over my bottomless, sex starved sister in law, she quickly pulled the straps from her vest top and bra from her shoulders down her arms before pushing her top and bra down. She then reached in and pulled out one amazing tit before doing the same with the other. She looked up and asked if i liked. I did. Her arreolas a light brown topped with a erect, thick nipple. She ran her hands over then and pinched her nipples gently. Im now not far from exploding. I look down as she stares up at me. I tell her i cum loads. To which she replies i know. She suddenly wraps both arms under her large ample breasts. Squeezing them together. Her nipples erect and hot. She begins to urge me to cum all over her special boobs, cover them in my spunk.
It was literally 10 seconds before a told her i was gonna cum.
With one last pump, grabbed and aimed the end of my swollen, foreskin pulled back cock at the big amazing tits on offer. The first spurt, hit hard and splattered both tits. Another shot and hit her neck. I was now like a hose as more hot white cum over the now sticky pushed together tits. After a 6th spurt i wad done. Angie looked amazed at how much cum was on her breasts. It dripping from her nipples onto the sand. Angie moaned in delight and admitted she had never seen someone cum so much. She stood up now facing me. Still hugging her deipping baby gravy tits.
"Stand there" she told me.
With that she some how with one hand pushed her top and bra down passed her exposed arse and pussy, before it dropped to the sand with her shorts.
I stood still as stood opposite me, naked. She kicked he clothes to the side before giving me another cheeky wink. She let her tits go. They didnt hang low at all or sag. The just stood there. A slightly smaller version of Kelly Brook if you will.
She grabbed her left tit, an lifted it up towards her face which was on its way to meet it. Fuck this was hot. I could feel my cock twitching again. Thst hadnt happened so soon fter cumming, for years. Angie stood licking and sucking my load from her tits. After a few seconds she stopped. Looked back at me. "Mmmmm so sweet" she moaned in approval.
With that she turned and ran into the sea. Letting out a little squeel as the water was cold. I could see her bending over and washing her sticky tits. 30 seconds later she was back. Shivering and trying to dry herself off. Failing slightly. She quickly got dressed as i too also pulled my shorts up over my now semi hard cock.

Angie and i looked at each other again. By now some of the sex fuelled booze induced confidence and bluntness had gone. We both giggled and decided to make the 1 mile or so trip back to the villa. We were only silent for a few seconds before i told Angie that was amazing and how hot she is. Adding i hadnt been that turned on in years. She pretty much mimicked my thoughts. As we went on we realised we were drunk but had discovered we could help each other in a few ways. I didnt feel wrong for some reason. We felt if we were careful and clever we could have the best of both worlds.
Angie even admitted she loved pissing for me. As we arrived we saw Angie husband having a cigerette on the balcony as her parents sat in the garden having a nightcap.
We were asked about our night by her parents and with the talking it wasnt long before my wife joined us all. Nobody suspected a thing as we recoiled what we had actually done in the kareoke bar earlier.
Eventuslly we all retired as by now it was nearly 2am.


This was the start of what is now a affair filled with experimentation, exploration and filth...
