I went outside to breathe some fresh air and saw the girls walking arm in arm across the car park, wicked grins on both their faces.

"What're you two up to?" I laughed, but they just laughed and told me I'd find out later.

I did too.

At their request, I sat in the garden drinking a beer and thinking about my encounter at the bar while I rolled a few joints.

I really didn't know how mum would react, when and if the gorgeous little teen did actually arrive with her girlfriend the following night, but there was no doubt that I was determined to find out.

"Excuse me, can you tell me where two innocent little girls can go for some fun and games around here?"

I couldn't help smiling as mum's voice broke into my thoughts, I turned round and got an instant fucking hard on.

Two little schoolgirls stood behind me, holding hands and each one sucking a lollypop, tongues licking suggestively at it as they looked at me with wide sparkling eyes.

"If you help us to have some fun." Sarah lisped coyly. “We'll give you some strawberries and cream, I've got the strawberries."

"And I've got the cream." mum added, then giggled and crossed her legs, "But hurry up, 'cos it's melting."

I didn't need asking twice, they both screamed with delight as I dropped to my knees in front of Sarah and pulled the dainty white panties to one side.

"Oh yes," she giggled and ground her pussy into my face as I pushed my tongue into her and found a strawberry. Getting it out though wasn't as easy as I'd thought. But finally, it oozed into my mouth along with a few deliciously tangy drops of urine and mum then took her sister's place.

The cream was dripping into her panties, soaking into the thin white cotton, but there was enough left in her sweet little cunt to add a very different taste to the urine flavoured strawberry.

I thought I was going to come there and then as mum ground herself down onto my mouth, while Sarah stood behind her and unzipped my jeans.

A delicious stickiness surrounded my cock as Sarah eased herself down, I could actually feel the other strawberries inside her, being mashed to a pulp as I began fucking her in short, sharp jerks of my hips. I saw her hands come round onto mum's pussy, one finger joining my tongue inside mum and another finger strumming her clitoris like a guitarist.

"Oh you fucking bitch," mum groaned. "You're making me cum."

Sarah giggled, and I felt a finger squirming beneath my chin, a scream from mum announced the arrival of the said finger in her anus and she screamed out her orgasm as she flooded my mouth with a combination of piss and cream.

She rolled off me and lay on the grass beside me, legs splayed out obscenely as her sister fucked herself on my aching prick.

Reaching out to her I pulled my mother into my arms and kissed her, letting her taste the tangy mixture she'd left on my lips.

"I'm fucking her, mum," I gasped. "I'm fucking your sister."

"Yes baby." she sucked at my tongue and licked her juices from all around my face.

"I told you she's a horny little cunt didn't I?"

"I'm gonna spunk, fucking hell, yes."

Sarah collapsed on her knees and let me take over, I arched my back up off the grass, lifting her up with it and formed a bridge with my feet and my shoulders.

Sarah was climaxing wildly as she hung on like a bronco rider and my sperm jetted into her cunt in a series of long, hot spurts until with a shudder I collapsed back onto the grass, totally and utterly spent.

Mum and Sarah looked absolutely gorgeous in identical white thongs as we strolled down to the nearest beach bar, a refreshingly cold shower had livened us all up considerably. I thought with me in my brief white shorts, we made an attractive threesome. Neither of the girls wore anything else at all, not even flip-flops and I was very much aware of eyes following us as we walked along arm in arm towards the bar.

"Have you ever had that feeling?" I said to mum. "That you're missing something."

She laughed and said that she had it all the time, but still something was bothering me, I couldn't quite pinpoint it, I was still mulling it over as we reached the bar.

Turning to mum, I asked her what she'd like to drink, to which she replied.

"Vodka and coke with plenty of ice please darling."

"Sarah?"

"Vodka and coke with plenty of ice please darling."

The barman looked up and smiled, turned to the bar and then spun back round again, a look of bewilderment on his face, the three of us laughed as he looked from mum to Sarah, then back to mum again.

His face broke out into the widest grin I'd ever seen and he guffawed loudly.

"Tweens, har, har, har, I see tweens, dos tweens."

I started laughing with him but then I suddenly stopped, I knew what it was that had been bothering me.

Turning slowly towards the two girls, who just happened to be innocently gazing up at the sky, I said softly.

"Who's idea was this then?"

"Hers," they chorused and pointed accusingly at each other.

"Aw come on," I protested. "This just isn't fair is it?"

"No" they agreed, "But it's going to be a lot of fun isn't it?"

My mother had had her nose pierced too, in exactly the same place as her sister and had even found an identical stud to wear through the bloody piercing.

"I theenk you lucky man senor, no?" the barman chortled as he served their drinks. "And what weel you have to dreenk?"

The girls almost collapsed in a heap when I replied with a perfectly straight face.

"Vodka and coke with plenty of ice please darling."

They wandered off arm in arm in search of an unoccupied table. I waited until they were about ten feet away.

"SARAH!"

"Yes?" they both turned and answered in unison.

All I could say was, "Shit." before I joined them in a fit of the giggles.

We stayed there for a couple of hours, content just to look and admire all the semi-naked and completely naked sun worshippers whilst getting slowly and pleasantly pissed.

The girls had a lot of catching up to do and set to their task with a will, gossiping and laughing and positively lapping up all the attention they were getting from the other occupants of the beach.

They were both obviously very touchy, feely sort of women and their hands seemed to flutter everywhere as they got reacquainted with each other.

Several times they stroked each other's thighs and even kissed each other tenderly on the mouth, in a genuine and beautiful show of affection.

I just happened to glance out towards the sea when I saw two familiar faces walking along kicking their feet in the surf.

"Paige," I shouted, and they looked up in surprise, Mum and Sarah looked up too, equally surprised as I shouted again,

"Paige, Claire." then they recognised me and came running towards us, waving and laughing.

""Hi Jamie," Paige kissed my cheek and said with a giggle.

"We were just talking about you."

"Really?"

"Yeah, I was telling Claire that you said you were staying with two- - - -, Oh my God."

She saw mum and Sarah smiling at her and put her hands to her face in shock.

"Oh my God," she repeated, "You ARE staying with two girlfriends, but you never said they looked like this."

"Hi," mum ( or Sarah ) stood up and kissed her, continental style on both cheeks, then did the same to Claire while Sarah ( or mum ) did the same thing too.

"So how do you three know each other?" said one of the twins and I butted in to answer before Paige could even open her mouth.

"I can honestly say Suzy, or Sarah." which provoked gales of laughter from the two newcomers, "that within a minute of me meeting Paige, she had a hand in her panties."

"Mmm, lucky hand," they chorused and promptly dispatched me to the bar for more drinks.

The barman greeted me with a, "You not just lucky man senor, you fucking greedy man too, no?"

"Yes," I agreed and silently hoped my father was having such a good time fucking his secretary, that he'd never want to return.
