Readers of this very good site - this is the penultimate story of my romance on holiday in 1992 with my sister-in-law ‘Hilary’. If you have followed my other two sexual encounters with my sister-in-law you know the first one happened in the apartment whilst my wife was sick in bed the second on the beach after we went out on our own but after the passionate sex on the beach we got back to the apartment and both were feeling a lit bit nervous and ashamed … after all how long could we get away with it? My wife hadn’t realised a thing and I especially was still feeling very guilty. On the Friday of the first week my wife was feeling better and things were back to normal but when I looked at Hilary I only saw all the naughty things we got up too. Anyway on the Saturday we all decided to go to the beach for a bit of sunbathing and R and R so we settled about half way up the beach strangely we were using the same type of sun beds and umbrella’s from which we had sex a couple of nights before which only took my mind back. We all settled on the sun beds and Hilary as usual was causing the local guys to hover round like flies I remember she was wearing a light blue bikini and it was showing off all her curves. All three of us spread out on the beds Hilary was led on my left and my wife was on the right … how lucky was I eh … but I was secretly and slyly eyeing up ‘Hilary’s’ body right from her toe’s up her legs and then the fabulous gap between her legs where I could just make out her exquisite mound and then up further and the gap between her cleavage and slightly protruding nipples…I had to turned over as I sensed my cock was throbbing and wanting to be stroked either by myself or if lucky by Hilary again, but I had to get this out of my mind. Just after midday after we had been drinking fairly heavily during the morning probably because the wife was feeling a lot better and also the holiday was back on track I was shocked after Hilary looked over to my wife and said, ‘shall we go topless its not a problem for me, and I really want to get a top half tan?’ My wife quickly replied ‘Yes that’s a good idea, lets do it’ and turned to me to ask what I thought and I just smiled, and then right it front of me both of these women unhooked and took off their bikini tops I watched as their breasts slipped free and they both giggled like schoolgirls I do remember a group of blokes about 15 yards from us spending the next 10 minutes with their tongues hanging out. We were all now relaxed and because of the blazing sun we all decided to get into the sea to cool off and I grabbed the snorkel and glasses because the sea was so clear we all swam about for about 10 to 15 minutes I remember looking at my watch and it was 2.15pm but my wife got out as she was a bit nervous because she was scared of the apparently prevalent jellyfish. Hilary and me carried on swimming about making small talk and I slipped on the snorkel and started swimming about looking at the small fish also I was trying my best to avoid Hilary because I knew I could get into trouble again. I was swimming about under the surface when I spotted Hilary legs ‘I knew these legs from 15 miles away’ but nearly took a mouthful of seawater as I swam towards her I realised she had dropped her bikini bottoms and they were hanging just above her knees and focused and could see the middle finger of her left hand pointing towards her exposed and NOW ‘newly’ shaven cunt, I decided to swim closer and as I reached out my hand to touch her she swiftly pulled up her bikini bottoms to prevent me from touching her. I came up out of the water about two feet from Hilary and she was grinning all over her face and as I wiped the seawater from my eyes Hilary had her lips apart and flicking her tongue in and out to mock me obviously giving her a good licking. I pushed the snorkel back over my head and walked a couple of steps towards her I knew where this was heading but really could not stop myself. As I moved in slowly Hilary’s breast’s especially were glistening with seawater and sun oil and her nipples were erect and so so suckable, I remember saying to her that ‘this is fucking bad news we are going to get caught’ and Hilary just said quietly ‘No no we wont IF we are really careful’ and I don’t know why I did it but I sank down to my knees until the water was splashing over my shoulder’s probably because I just loved looking at her body and breasts and then carefully put my arm out until it touched the inside of Hilary leg. Hilary did exactly the same and dropped down in the water and we just smiled at each other and without a word I slowly and carefully moved my hand up until it was starting to touch the inside of her thigh she was staring at me and wanting me to touch her cunt. Without getting to close to each other I brought my hands skilfully closer to the inside of her leg and started to move my hands up the inside of her thigh until I stopped at the material of her bikini bottoms, I put two fingers together and pressed against the front of the material and Hilary looked back at me and smiled I rubbed my fingers up and down flicking my middle finger against the material and slowly was rubbing her clit I guessed just by looking at her face that my fingers were having the correct response. Hilary then pulled the material to one side so now I could move my fingers in on that beautiful cunt, and as I brushed past her hand I instantly could feel the softness of her cunt and quickly found her clit and started to rub it with my index finger she smiled and said ‘nice and soft eh’ and I flicked her clit again with my finger and she closed her eyes as I touched her clit I noticed her body twitch and her nipples started to grow and getting more erect I took my chance and pushed one of my fingers deep into her cunt and she opened her eyes really wide and said quietly ‘you naughty boy’. I remember saying to her ‘I know this is naughty but lets pretend we are just chatting and splashing about in the water and I will play with your shaved cunt’ and Hilary just smiled and said ‘I love it …. Fucking love it’ .. I really don’t know how we didn’t get spotted but we were both fairly drunk. I was on my knees and the water was just up to my neck Hilary was also on her knees but under the water my hand was slowly and skilfully playing with her cunt she was pretending to hold a conversation so it looked natural but she was losing control this was SO bloody naughty ‘and’ dangerous but it was also a huge turn on my finger dug deep into her hole and she was doing her best to just look around also to see if anyone was aware of what we were doing but the spot we had chosen was more for adults and luckily was down the far end of the beach. Hilary kept saying ‘I love your fingers fucking me’ and the more I played with her cunt the more she wanted me at one stage she took hold of my hand and held it in her cunt whilst she moved about writhing and fucking my fingers. I could see some people swimming out past us so I stopped and Hilary looked at me as if she could kill me and reached under the water to pull up her bikini bottoms… I was looking around just incase was my wife who was swimming out. I was looking around but there was no way I could see my wife from where we were playing about…and then without warning one of Hilary’s hands had slipped up the left leg of my swimming shorts and was heading towards my balls and cock I instantly let out a sigh and said ‘fuck’ and turned towards her she had a wry smile on her face god she was so bloody naughty but I knew from a distance it ‘still’ looked like we were just splashing about and chatting but how long could we keep this up? Hilary had skilfully got her hand up inside and was gripping on the bottom girth of my cock and squeezing my balls it didn’t take long for some sort of reaction and slowly and gradually my cock started to spring into life I could feel her hand around my cock as it was growing in her hand she was also gripping it fairly tightly and her eyes were glazing over she was slowly and carefully moving her hand up and down the length of my cock and starting to wank me off … I knew I was in trouble AGAIN. Then just as I was enjoying it she let go of my cock and pulled her hand out from my shorts and then swam backstroke about 10 feet back from me and then turned towards me and dived under the water I could see briefly her beautiful ass disappear under water and THEN before I had a chance under the water she had pulled down the front of my shorts took my cock in her right hand and then I felt the warmth of her mouth as he started to force it to the back of her mouth!!! For gods sake I was thinking this is BAD!! She quickly and skilfully moved her mouth up and down my cock for about 15 seconds at the same time I ran my hands down her back until they reached the top of her bikini and then slipped both my hands inside and gripped her ass really hard and try to get one of my fingers near her cunt but that was enough and she suddenly appeared back on top of the water and smiled like nothing had happened. I looked around again to see if anyone one was about and Hilary said ‘lets go out a bit deeper’ and I followed Hilary out until we could just touch the bottom Hilary was treading water and I knew she was teasing me she swam towards me and grabbed my hands and we were mocking a play fight my cock was really stiff at it was rubbing against the material of my swimming shorts she whispered ‘drop your shorts a bit’ and I dropped my hands under the water and pulled down my shorts and loved the feeling of the water around my cock and balls. Hilary also dropped her hands and I was guessing she had slipped her bikini down as well, we playfully grappled with each other as if we were loving ‘couple’ I pulled Hilary towards me and my cock touched the inside of her leg and she grinned and whispered in my ear ‘come on slip it in’ we splashed about again but this wasn’t easy my cock brushed up against her cunt again and she would mouth ‘nearly’ then I grabbed both her arms and we moved about in the water again on one occasion we eventually got my bell end to penetrate her luscious mound but only just a couple of inches at first. I was getting really pissy now because I ‘wanted’ her cunt and Hilary loved teasing me, she grabbed and squeezed my cock and rubbed it up and down quickly which was driving me mad, on one occasion she took my cock in the palm of her hand and guided it towards her inviting cunt and smiled at me as if she was going to let me slip it in, as my bell end inched slightly into her warm cunt sensation was mind blowing only then to be pushed back teasingly ….I had enough and quickly looked around just in case someone was close and planned to make my move. I moved forward and carefully and skilfully my cock was near her cunt again I knew she ‘really’ wanted me so I made my move again my cock brushed up against Hilary’s cunt, but this time I moved forward swiftly and she wasn’t ready and had no reply and my very hard cock slowly entered her love hole inch by glorious inch until my cock had slipped in half way what a glorious feeling and Hilary’s breathing was already faltering I knew I had her. Hilary eyes were now shut and her mouth was open I knew she had lost the plot again and I let go of her left hand leaving my right arm free and quickly reached under the water and grabbed hold of her ass and pulled her towards me and my cock slid slowly and carefully right into her cunt until our bodies touched Hilary just groaned and I pulled her tightly and her body twitched and she let out a moan again and now she could do nothing as she was embedded on my cock. We gazed at each other and the passion was building up again I quickly looked around just incase there was anyone near but luckily we appeared to be on our own and a fair way out. Hilary was trying to shift and move her body backwards and forwards along my cock and was groaning but I was holding her so close that she had no control at all and she called me loads of dirty fucking names but that made my reaction worse and I dropped my other hand and put this around the back of her other ass and my feet were just touching the bottom and Hilary’s legs swiftly entwined around my back, I was now holding Hilary up and her tits were nearly in my face we stayed like that for about 2 or 3 minutes it may have looked very suspicious, so Hilary was trying to playfully hit me as if we were having a fun-fight but little did everyone know on the beach including my wife that under the water I had my hand gripped tightly around her ass with her long legs now entwined around my back and my throbbing cock was embedded in her warm cunt, we stayed like that for a matter of minutes and Hilary was loving it don’t know about you but there is nothing like concentrating on one thing whilst being naughty with something else, I then suddenly spotted Hilary’s bikini bottoms floating away she told me to leave them but I said ‘how could we get back onto the beach with you totally naked’ we both gazed at each other and the tension was now even far worse and the naughtiness of the whole scenario made it dangerous who would hold out longest? and as they drifted and drifted I slid my cock out slightly and forced it back in that made Hilary grip onto me even more I told her I must go to pick them up but she held me tighter and I grabbed her ass and forced my cock into her as hard as I could and got angry ‘fucking let me go’ but I couldn’t move and they were drifting further away finally she let me go and I slipped my cock out of her cunt and she gave me one of her evil stares. I pulled up my shorts and swam over to retrieve her bottoms but Hilary didn’t care she just stood there and called me more names. ‘I want your cock NOW she said’ but I argued back and said ‘this is bloody dangerous we are going to get caught we have been out here for about 45 minutes’ I really don’t know how Hilary did this but she seemed to find places that I never could ever think off .. I handed over the bikini bottoms and she slipped them back on but about 25 yards from where we were swimming were some small boats bobbing about and she said ‘follow me’ she swam quickly doing breast stroke ‘Great breasts’ I was thinking. There were six or seven boats tied to buoys and Hilary swam behind one of them and I followed she stopped for a couple of seconds and looked about we had swam so far out that there was no one about but it was obviously a lot deeper and I could not see the bottom. ‘What here?’ I said.. and Hilary said ‘Oh no…. lets get in this boat’ .. I stared back at her in disbelief but she said ‘come on climb up the ladder keep your body low and slide in’ … for a start I still had a semi hard cock so keeping low was going to be difficult but due to the way the tide was running the back of the boat was obscured from the beach so I slowly and carefully climbed up the alloy ladder and the back and stupidly muttered ‘Hello’ just incase someone was in the boat. I slid in the back of the boat it was a neat and tidy boat with a large full bench seat at the back and seat each side for the driver and passenger also small walking gap in the middle, I sat on the floor and after a couple of seconds Hilary appeared and I moved over to let her in. She smiled at me and said ‘how long have we got?’ and I replied ‘about 20 to 30 minutes without your sister getting really suspicious’ she smiled and I moved backwards and she moved her body on top of me until her tits were dangling in my face I was mesmerised again and she climbed over me and started to kiss me passionately her tongue was probing the inside of my mouth, I instantly started moved my hands up until the were placed on her breasts and I stared to pinch and play with her nipples she was instantly back in the zone again and I could hear her moan once again. I was led on my back with Hilary on all fours on top of me she occasionally stopped kissing me and made me lick and nip at her protruding nipples which were so sensitive and with each bite Hilary squirmed and her ass moved and rotated as she slapped her tits against my face. She suddenly slid down my body and I knew where she was going and passed my midriff and before I knew it she had pulled down my shorts and my semi erect cock was laying to one side she pulled her wet hair back over one of her shoulders and bent right down and was inches from my twitching cock…. ‘Shall I suck it’ she said …? ‘Yessss’ I said …!! ‘How much do you want me to suck it’? ‘Fucking loads I replied’ ‘Ok I will’ she replied and purred like a dirty whore she lifted my cock with her hand and carefully and it slipped into her mouth she didn’t suck it she just got this huge thrill from feeling my cock stiffen whilst in was in her mouth and I thought it was fucking amazing too but as she bent over me with her eyes shut I could feel the blood pulsating in my cock and it was gradually and slowly growing in her mouth she was moaning again, my cock gradually grew and went erect Hilary head also moved up until her head was above my cock and then she started to work on my cock like a skilled pro. I led back and looked up at the blue sky and then looked back down my body and saw this girl 8 years my junior working furiously and skilfully on my cock with each stroke she moaned and the feeling of her wet hair in my body was driving me mad she occasionally looked up and gazed at me to make sure I was enjoying her using her mouth at one stage she said ‘this is my cock MY fucking COCK’ and sucked it really hard and what with her tits dangling on my legs I had to do my best not to shoot my load. She stopped sucking on my cock and smiled at me and then skilfully pulled down her bikini bottoms without standing up she came towards me on all fours and my cock was twitching in anticipation of her now approaching cunt. We faced each other and both grinned I knew Hilary’s cunt was hovering over my cock and I wanted it really badly and so did she … I lifted my hips and my cock touched the inside of her leg and then it touched her clit she sighed again but she was teasing me and then slowly and carefully she moved her body down on my cock until inch by inch her warm cunt engulfed my throbbing cock we both sighed until all of it was buried in her cunt. For a number of seconds we didn’t move we just kissed passionately and Hilary occasionally moved her ass and body around my cock it was like we were waiting for the race to start. Hilary pinned my hands behind my head and looked down at me her breasts were dangling in my face and I occasionally nipped at either the left or right nipple and she squirmed when I got it right she kept saying ‘naughty naughty’ and then raised her ass up which released my cock out of her cunt and then skilfully she dropped her hips so it slipped back down over my cock again each time she did this we both sighed and we knew this would not last forever. Again she lifted her ass so my cock slipped out of her cunt and she teased my cock with her clit and the perfect warm mound of her cunt this was driving my crazy, she slipped my cock back in again but this time she decided to sit up on my cock my hands were now free and as she sat on my cock I reached up and started playing were her nipples and perfect breast, Hilary now had her eyes closed and was starting to lose control and working her body up and down on my cock she worked on my cock for a matter of minutes her tits were bouncing up and down and her hair was tossing about what a sight this was. I slipped my hands behind Hilary’s peachy ass and grabbed both cheeks as hard as I could and Hilary leaned forward and her tits were now pressed again my chest I was now going to fuck her so hard she was never going to forget it … slowly and carefully I gripped at her ass and stretched her cunt open and started to pound at her warm fanny I was pushing my cock in as far as I could and Moving my cock inside and grinding my cock until her breathing starting to increase I realised she was starting to bite at my neck and started to whisper dirty things in my ear ‘fuck me hard you fucking bastard’ she said ‘fuck me sooo hard with your cock’ and we started to build up an almighty orgasm…… BUT as we know with Hilary she had other ideas and just as I was getting to the final few strokes she whispered in my ear ‘please please let me have it doggy and fill me with all your spunk’ I was fit to bust and wondered how much more I could take but this women didn’t care she just loved my cock she smiled at me and my cock slipped out of her now wet and throbbing cunt and turned around so her head was resting on the seat of this boat we had climbed in and her ass was sticking up in the air ready for my cock to pound into her for one final time. I shifted over on my knees but luckily we were covered by the fairly high side’s of the boat … how could anyone refuse to fuck this beautiful 22 year old and slowly and carefully I bent behind her and started to tease her clit again with my cock she loved this. I grabbed the base of my cock with my right hand and pushed my cock very slowly against her clit and rubbed it a couple of times and then slowly pushed my cock in by about 3 inches and then pulled it out and she squirmed and bucked and started calling me names again, I started teased her and slapped her ass with my hard cock and she was moaning again I called her a ‘dirty whore’ and she just replied by telling me ‘she WAS a dirty whore and loved cock’ and was gripping onto the back of the seat as if her life depended on it, I slowly and carefully inched my cock in again, I loved to tease her and she hated but I was now in control and she was mumbling under her breath ‘just fucking give it to me’ and I slapped her ass really hard and she squealed with pleasure … ‘How much do you want it?’ I said and slapped her ass really hard. ‘I want it lots and lots and lots’ she begged and ended with ‘pleaseeeee’ I thrust my cock in so hard her head was pressed up against the back of the seat and she gasped … ‘fucking hell’ ‘Like that’ I said and she said ‘Yessss like that’ I took my cock out again and teased her clit and she was moving her ass up and down in an attempt to get my cock back in again but I waited until she got really annoyed and was calling me names again and she screamed out ‘give it to me NOW you bastard!!’ …. And I duly obliged and thrust my cock in so hard my balls slapped against her cunt. She let out a whimper and shouted ‘Ohhhhh Fuuuuuuck’ but I also knew I was nearing to shooting my load but I just had to hold out as long as I could. I pushed my cock in until I had no more to give and started to grind and move my cock about inside her and could feel my bell end touching everything that was positively sensitive and Hilary’s breathing was getting deeper and at one point I must have touched a G-spot because she squirmed and whimpered and I felt her inner body finally giving in. I slapped her ass really hard again and could see the mark on the white parts of her peachy bum she was building up to a climax and I could NOW feel it coming through her body so I gripped both sides of her ass and pumped my cock into her and fast as I could occasionally slapping her ass before she finally started to buck and grind and then in an explosive couple of seconds she finally orgasmed and took one of her fingers and placed it in her mouth to nullify the screams she was trying to let out, even though her finger was placed in her mouth the noise went on and on and on and on it was so sexy and so dirty. BUT I had yet to shoot ‘my come’ and knew I could now use her cunt to give her a good shagging she was moaning and groaning and I pushed her hard against the seat, ‘Now do you want my come’ I said. ‘Oh please please fill my cunt’ she pleaded ‘How much do you love my cock Hilary because I am going to fuck you again before we go home’ Hilary was building up to another orgasm and her ass was pushing against my cock I was starting to build up to some long strokes and smacking my cock in so hard my balls were bouncing against her. She carefully put her hands between her legs and grabbed hold of my balls and played with them as I started to build up to my final strokes I was lost in total ecstasy and after about 30 seconds I could feel my come starting to build up and then in one final act of pleasure my cock released it juices and it sprang into her cunt we both let out a huge moan at the same time and I felt like I was going to collapse again. We stayed in this postion for about 45 seconds and then I moved back and my cock slipped out I gazed back at her and saw again my come trickling out from her beautiful fanny. How much more could I get away with …? I was already wondering if my wife was searching the beach? We quickly put our costumes back on and slipped down the side of the boat into the sea and I swam behind the boat about 30 seconds before Hilary and I speedily headed back towards the beach my head was spinning my heart was racing…. I swam up to the shore and noticed the ice-cream flag which was just near to where we had our beds and slowly walked up the beach, I could see our bags and beds and could see my wife led back on one of the sunbeds I slowly approached the bed and bend over and said Hi…. She awoke from her sleep and muttered … ‘god I must have fallen asleep, where is Hilary?’ and I replied quickly ‘just behind me we have been swimming for ages.’ My wife sat up and Hilary followed and she knew absolutely nothing of what had transpired we all relaxed back on the beds BUT the rest of the day my head was still in a spin…. Next week I will tell you how we spent the final night before we flew home.
