It was a beautiful, long, slow and very tender coupling. We wrapped our arms around each other and just sat there with mum's breasts squashed against my chest, our mouths occasionally touching whilst I told her my thoughts and desires!

"If he really loved you mum, he wouldn't be fucking her would he?"

"Well I'll tell you something you don't know Jamie," she said and squeezed her vaginal muscles around my cock. "But you must never, ever let you father know that I've told you."

"Of course I won't mum, I promise."

"Okay." Then she sighed and wiggled her bottom sexily, "Your cock is doing wonderful things to my pussy you know! Anyway as I was about to say, it's not always been like this with your father and me, when we met, we spent nearly as much time in bed as we did out of it. Every opportunity we got, we were at it like rabbits and remember I was still only sixteen then."

That made my cock jerk inside her and she giggled. "Pervert, I can read your mind."

"I bet you were a sexy little bitch," I said and reached round to caress her bum cheeks.

"Well put it this way," she snaked her tongue between my teeth. "Try to imagine me, a nice, innocent little schoolgirl sitting in class, panties soaking wet and dreaming about spending the whole evening in bed with a twenty-three-year-old man."

"Wow, sexy," I pulled her buttocks apart, and she moaned as my finger ran lightly over her anus.

"That's not all," she said and began moving up and down on my cock.

"Can you imagine that same innocent little sixteen-year-old sitting in the classroom with no panties on at all, because her best friend has got them in her schoolbag, just like that sixteen-year-old has got her friend's panties in her schoolbag?"

"Oh fuck mum, is that true?"

"Oh yes! Everything I'm telling you is true, that's why I don't hate your dad, because I'm not exactly lily white you know."

"No, I know you're not," I laughed and thrust upwards into her pussy. "You're pink in a lot of places, pink and wet."

"Mmmm, nice," she sighed and rotated her hips lewdly, "But let me finish, can you imagine the two sixteen-year-old girls in bed together, doing everything to each other, tongues, fingers, toys, even bananas?"

"Who was she, mum?" I could sense that I wasn't going to last much longer.

"Push that finger in," she said softly and moaned with pleasure as the digit slid easily into the little puckered hole.

"Can't you guess?"

I didn't have a clue, and I was having trouble concentrating on my thoughts anyway with my horny mother impaled not only on my cock but a finger too.

"God mum no, tell me."

She giggled again and flicked her tongue into my ear.

"Think about it Jamie, think about how two sixteen-year-old girls could go to bed together, sleep together, even bathe together without raising suspicion."

For the life of me, I couldn't think who it could have been, her sphincter muscles were squeezing my finger, pulling it deeper into the deliciously tight recesses of her anus. Her vaginal muscles were milking my cock, her breasts were squashed against my chest, and she was licking inside my ear. How the hell was I supposed to think of anything else but that lot?

"I'm cumming Jamie," she hissed, "Fuck me baby, fuck mummy's hot little cunt, oh God yes."

I rammed my finger in knuckle deep and felt my own climax rushing towards me, towards where her juices were soaking me.

"Who mum, tell me please?"

"Jamie, oh fucking hell Jamie, you're so big," she clung to me as she came and the last words she was capable of as she surrendered herself to her climax were, "I'm a twin Jamie, it was your aunt, Sarah."

I thought I was never going to stop spurting in the warm, clutching softness of her cunt as she spasmed in ecstasy, fucking hell she was telling me she'd had a lesbian affair with her own sister.

Still naked we walked down onto the beach hand in hand and into the beautifully warm water of the Mediterranean.

"So where does dad come into all this?"

She looked at me and smiled.

"For someone with the sexual appetite that you've got, you're a bit naïve you know."

It was said kindly though and she squeezed my hand.

"Your dad was fucking us both."

I was still digesting what I'd been told as we waded deeper letting the water take us off our feet. We swam lazily for a few minutes then came together again and stood holding each other.

"So when did your, er, your thing with aunt Sarah finish mum?"

"Wait a minute." she stood statue like, smiling at me, then shuddered and giggled.

"That's better, a girl's gotta go when a girl's gotta go."

I threw my head back and laughed.

"Have you just had a pee?"

"Yup," she looked up at me like a cheeky kid. "Why?"

"Oh mum for Christ's sake, I've got to walk back up the beach."

Grabbing her hand, I waded back towards the beach.

"Come on quick, I'm getting another hard on."

People looked up at us and smiled as we ran across the beach, water dripping off us, mum's gorgeous boobs bouncing delightfully and my cock visibly growing with every second.

At last, we reached the safety of the villa's garden and leaned against the gate, laughing like two naughty children.

"Did that turn you on then?"

"Now who's being naïve?" I said and pointed down to my erection.

"My God Jamie, you've only just cum."

She dropped to her knees and kissed the tip of my penis I felt myself going red with embarrassment as her lips closed over me.

"I just think it's sexy mum," I said, "I'd love to watch you next time."

Looking up at me, she winked sexily and cupped my balls.

"What would you say if I asked you to do it over me mum?"

She took her mouth away from my cock and stood up again, wrapping her arms around my waist.

"I'd say we'd better go and put some clothes on."

"Why?" I was back to being confused again.

"So we can go down to the village and have a few beers of course."

She looked gorgeous in a little white dress, not quite sheer but thin enough to show a sexy white thong and the rose coloured circles of her nipples through the flimsy material. I wore a white tee shirt and shorts and felt the proudest man on earth as we strolled down to the village.

"Hey, I've just remembered, you never answered my question did you?"

"Which one was that?" she asked, but I know she knew the one I meant.

"The one about you and Sarah and dad, when did it finish?"

"The reason I didn't answer was that I've been thinking about a little idea I've had, so I'll answer it and then ask you a question okay?"

"Okay."

"Well, it never did end really, as you know John, Sarah's hubby works on the oil rigs and only gets off for a month in every four months."

"Yeah I know, he earns a fortune."

"Well every so often when he was at home, the four of us got together, you know for some fun."

"What, like swinging fun?"

"Yes, me and Sarah, me and John, Sarah and your dad, the only combination that doesn't happen and never will, is John and your dad."

"Bloody hell mum, that's so cool."

She laughed again, that delicious little tinkle of gaiety that I've always loved, but now it sent shivers down my spine every time I heard it.

"Mmm, we certainly enjoyed it, but unfortunately it's never happened since your father started seeing that bitch in his office."

"Hmm," I said thoughtfully. "Now what about your question?"

We reached a little bar on the seafront where we could sit and look out over the beach whilst enjoying our ice cold lagers.

"Well I know we're going to have a lovely, sexy time here, just the two of us, in fact," she giggled again, "I'm wet already thinking about what you asked me to do earlier on."

She put her hand on my growing bulge beneath the table, "And I suspect that by the time we have to go home again, my poor little pussy is going to be in need of some rest and recuperation."

"It certainly is." I laughed as her fingers found the shape of my cock.

"Well John's not due home for another two months, and I just wondered if perhaps you think you could handle another sexy bitch who's every bit as horny as me?"

"Jesus Christ." I nearly dropped my beer in surprise.

She looked questioningly at me as I reached for her purse.

"What're you after darling?" she was unsure now and wondering about my reaction.

I laughed out loud and pulled out her mobile phone.

"I presume you know her number."

“Hi sweetie, how are you?”

"Oh I'm fine baby, in fact, I'm more than fine, I'm absolutely bubbling."

I left her to it and went to the bar for two more drinks, what mum had just told me had shocked me, although it was undoubtedly a pleasant shock!

The thought of her and her sister making love to each other was mind-blowing, every man's fantasy, (never mind every horny, eighteen-year old's!) and I could hardly wait until she got here.

"Well?" I asked as I returned with our drinks, she'd just put the phone down on the table and was smiling to herself secretly.

"She can't come," she said simply and watched as my face fell.

"Until tomorrow night."

"Aw mum," I laughed and leaned over to kiss her.

"Really, is she really coming tomorrow night?"

"Well actually she said she was coming as I told her about us two." she laughed. "She made me tell her all the dirty bits while she played with herself too."

The only other couple on the balcony drained their glasses and left with a polite nod in our direction. Mum looked round and stood up quickly.

"Look out for anyone coming this way," she said and walked across to the far corner of the balcony, out of sight of the bar.

Puzzled, I did as she said and I got even more puzzled as she just stood against the wall smiling at me.

"What're you up to mum?" and then I saw it, the little trickle running down the inside of both her thighs.

"Oh my God, mum." I gasped. "Christ, you're doing it!"

She giggled and raised her dress letting me see the warm, golden urine gushing through her tight little panties and splashing on the tiles between her feet.

"God I love this," she said softly. "It makes me so fucking horny."

"What do you think it's doing to me?" I laughed. "Jesus, mum, that's the sexiest thing I've ever seen in my life."

I saw a couple heading our way from the bar so we drained our glasses hurriedly and left, laughing at the thought of what they'd make of the little puddle she'd left behind.

I was as horny as hell when we got back to the villa and mum reaped the benefit as I pushed her back against the door and dropped to my knees.

"Jamie," she gasped as I clamped my mouth onto the wet cotton of her panties. "No Jamie I'm, oh my God. Yes, Jamie, I'm cumming."

I sucked the wetness from her sodden panties, my nose pressed against the prominent bud of her clitoris as she thrust her hips against my face.

"Jamie, oh fuck baby." and she shook as the waves of pleasure washed over her and she sank to the floor, a smile of sheer pleasure on her beautiful face.

"I don't believe that." she laughed. "No one's ever made me cum before without actually touching me, ooh wow, I'm still shaking."

I kissed her on the lips and she moaned again as she tasted herself. "Jamie go to the store down the road and buy some more lager, I'll have a surprise for you when you get back."

I watched as she scampered upstairs, her sexy little bottom peeking out from under the short dress and I felt a surge of love for her. Yes, it was love, not just lust, I was certain of that, Jesus I was falling in love with her, my own mother.

"Where are you, mum?" I shouted as I returned with two dozen bottles of lager straight from the store's cooler.

"Give me two minutes baby," she shouted. "Get us both a lager and make yourself comfortable in the garden, I hope you're ready for this."

I was more than ready for it, as the semi-erect cock in my shorts was telling me, the little episode in the bar had left me wanting more, much more.

"Well, what do you think?"

Her breasts bulged invitingly, almost over the top of the lacy white bra, white seamed stockings were held up by a matching white suspender belt. Apart from white high heel shoes, her only other garment was a tiny white g-string, pulled up so tightly into her pussy slit that the beautiful hairless labia bulged out from either side of the narrow strip of lace.

I was practically speechless, she was, without a doubt, the most beautiful woman I'd ever seen in my life.

"Oh mum," I said throatily. "You're beautiful, absolutely beautiful."

She blushed as she kissed me and I wrapped her in my arms.

"You really do know exactly the right things to say," she whispered.

"I'm saying what I think mum, honestly, I don't want to touch you, you're far too gorgeous."

She giggled and ground herself wantonly into my bulging erection. "You'd better do more than touch me buster."

Her tongue wormed into my mouth, "I'm hot and horny as hell, and I need you to make me scream tonight, if I'm going to be sharing you for the next month, I'm having you all to myself tonight."

"Hey mum, I'd rather just have you than let there be any kind of conflict, honestly."

But she just giggled and tongued my mouth again as she unfastened my shorts.

"Believe me, darling, there won't be any conflict at all, don't forget that Sarah and I are twins. We're on exactly the same wavelength, we always have been, do you realise that when I went into labour before giving birth to you, Sarah had labour pains too?"

She shimmied my shorts down and took my cock into her mouth just to bring it to full erection.

"Now sit down again while we get pleasantly pissed and I'll tell you a few things about your aunt and me.

I groaned when she took her mouth away, but she ran her hand between my legs and prodded a finger gently against my anus.

"Sarah and I are going to show you things that you've never even dreamed of," she said softly. "Things that will make your toes curl."

We sat down together on the double swing, and I put an arm around her shoulder as we both swigged from our bottles. Gently I eased a breast out of its lacy cup and ran a thumb across the pert little rose coloured nipple.

"I'm going to give you so much spunk over the next few days, you'll be dripping like a tap."

She sighed happily and squirmed around to sit on my lap; like she'd done earlier with her legs wide open straddling mine.

"That's where you're mistaken my sexy stud," she laughed. "Because my kinky sister will lick every last drop out of me, to make room for more."

She lifted the naked breast up to my mouth and lowered her head so that her tongue duelled with mine around her nipple.

"Wow," I laughed. "Really?"

"Really," she confirmed and rubbed her panty clad pussy sensuously over my cock.

"Is there anything you haven't done then?" I asked, and my cock twitched as she giggled and her answer began trickling through her g-string.

"I've never peed over my son before!" she said softly and stood up to let me see as the trickle became a flood. Reaching behind her, I slipped a hand between her legs and caressed her tiny little anal cavern.

"Push it into me," she sighed as she continued to pee in my lap.

"Oh God yes, that's nice, but has your finger got a friend to join him?"

She sat down again and moaned as my two fingers opened her sphincter and I began fucking her tight little hole.

"Ooo!Jamie." her mouth formed an "O" as I removed my fingers and replaced them with the head of my penis.

"Oh fuck yes baby, oh yes, do it to me, fuck my bum, Jamie."

Our mouths locked together as she sank down on me, slowly the swollen dome of my cock squeezed into her anus.

"Mum," I gasped into her mouth. "Christ Almighty mum, I'm doing it, I'm fucking your bum."

She gripped my head with both hands and awkwardly lifted both feet up onto the swing beside me, my cock went deeper, and she squirmed in delicious agony.

"Oh Jesus," she deliberately allowed a long string of saliva to dribble into my mouth. "Jamie, this is so fucking sexy, so, so. . . ."

She could hardly speak as I thrust upwards.

"Dirty?" I suggested and she squealed.

"Fuck yes, dirty baby, that's it, it's so fucking dirty."

Another flood of urine spurted out through her g-string as she started to come, clinging to me, writhing with pleasure, gripping me, milking me."

"Come for me," she hissed. "Fill me, oh fuck you dirty bastard, fill my fucking arse."

Suddenly I came, my cock erupted, and I rammed her down savagely onto my cock, I felt my lips curling into a snarl. I was beyond pleasure, the giving of it anyway, I just took my own pleasure, she screamed and tried to pull away, but I held her as my cock spurted jet after jet of thick, creamy spunk into her bowels.

Again and again, she screamed, she bit my tongue, my lips, her nails raked my back, but I held her as she jerked uncontrollably. Her eyes seemed to roll back into her head until suddenly I was empty and she collapsed on top of me, limp just like a little rag doll.
