Over at the new Stevenson home near Northolt, during the course of the Spring, Tom and his lads had finally got the swimming pool finished in between other jobs. However it wasn't until the beginning of the summer holidays that he decided that it was worth painting it and filling it with water.

'What are we going to do today?' asked Natasha as she and her twin brother met in their bathroom one morning just after term ended.

'Daddy was saying last night that if it was nice today we could put the first coat of paint on the pool.'

'OK, so what's the weather like?'

Andrew looked out of the bathroom window.

'I think it's going to be a scorcher,' he decided.

A scorcher it was and shortly after breakfast Jackie and the two youngsters set to work on the pool.

'Phew it’s hot!' gasped Natasha after a while, 'I think perhaps I'll start work on my all-over tan.'

Skipping up the steps she quickly shed her jeans, pants, and tee shirt. Andrew, who was painting the top edge of the pool surround, was highly amused. He put down his brush.

'I must go and get the camera,' he laughed and made for the house.

When he returned he found both Natasha and their mother stark naked, painting the wall at the deep end of the pool.

'Take one from the shallow end, back-view only,' instructed Jackie, 'Then we can put it in the house album.'

'OK,' he agreed, 'Can you look back over your shoulders and smile?'

The girls did as they were asked and Andrew took a photograph.

'I hope it comes out,' he said, 'You look priceless. I really like your hat, Mummy and Natasha's socks and tennis shoes.'

'You don't think we're good material for 'Playboy' then?' laughed his mother.

'Take off the hat and the socks and shoes and turn round and I'm sure you are,' chuckled her son, 'You look like sisters by the way.'

'My darling son!' exclaimed Jackie, 'Sometimes you say the nicest things.'

'Just telling the truth,' he replied, shrugging his shoulders.

'He's the most dreadful flatterer,' giggled Natasha and her mother took a swipe at her with her paintbrush.

'Less of that young lady,' she admonished, 'Otherwise, you'll end up a very strange colour.'

After putting the camera away Andrew returned to his job, shedding his clothes too before he took up his paintbrush once again.

'It's quite fun working starkers,' he laughed.

'Some jobs are OK,' agreed Jackie, 'I wouldn't fancy cutting down thistles like this though.'

'Or dealing with stinging nettles,' added Natasha.

'Wow!' gasped Andrew, clapping his hands over his crotch, 'What a simply awful thought.'

A week after the second coat had been applied, Tom announced that the pool was ready and the tap was turned on to fill it with water. The twins were very excited and rushed out at regular intervals to watch the level slowly rising. In just under two days it was full and the filtration equipment was turned on to begin the job of removing the fine particles of dust which were held in suspension and which gave the water a muddy hue. As soon as it cleared, Tom and his son set to work with the vacuum cleaner, to suck up every last bit of dirt off the bottom, before adding the initial dose of chemicals. Once the correct balance was achieved Tom turned on the heater to get the water up to a comfortable temperature.

'So when will we actually be able to swim in it?' asked Natasha plaintively, for to her the preparations seemed to be taking an awfully long time.

'Well, you could get into it tomorrow, but I reckon that it'll still be a bit on the chilly side,' replied her father.

Exactly twenty-four hours later, Natasha and Andrew stood on the side at the deep end, joined hands and hurled themselves in.

'It's fantastic!' cried Natasha as she surfaced, 'Come on in you two, it isn't really cold at all.'

'Can we ask Toby over to stay now?' asked Andrew.

'Of course,' agreed Jackie, 'I’ll 'phone his mother tomorrow.'

****

'Phew, thanks,' gasped Toby thankfully as his handsome blonde friend took over his bicycle which he had been pushing up Northolt Lane from the main road.

'You look rather hot,' observed Andrew, who was dressed only in a pair of red shorts and had flip-flops on his feet.

'I'm absolutely boiling. Isn't it a smashing day?'

'It's lovely. It took you a bit longer to get here than I thought it would. I've been waiting under the trees by the gate for almost half an hour. That's why I decided to walk down and see where you'd got to.'

'It's more uphill than I'd imagined. Some of it was pretty hard going, to be honest.'

The taller skinnier boy unbuttoned his pale blue shirt and took it off. Rolling it into a ball, he pushed back the lock of dark brown hair from his forehead and used it to mop at the sheen of perspiration that was threatening to trickle into his eyes.

You look as if you could use a glass of something cold,' laughed Andrew as he leaned the bicycle against the wall in the garage and began to untie the bag which was fastened onto the small rack behind the saddle.

'I certainly could.'

The boys went through into the kitchen and Andrew took a jug of something out of the 'fridge.

'Natasha's homemade lemonade,' he announced, 'It's very good actually.'

Taking a couple of tumblers from the wall cupboard he set them down on the breakfast bar and filled them to the brim. Toby picked one up and took a deep draught.

'Oh, that's great,' he said, smacking his lips appreciatively, holding out his glass for a top-up. He looked around him, 'This house is absolutely super you know.'

'It is, isn't it? We love it here.'

'I'll bet! Where's Natasha?'

'She was out by the pool last time I saw her. I'm not sure where Mummy is though. Come on slowcoach, finish your drink and we'll dump your stuff in my room and go for a swim.'

'OK,' agreed Toby draining his tumbler, 'We'll just rinse these out first though shall we?'

'You'll be getting me a bad name again,' grumbled Andrew as his friend washed out the glasses and set them neatly in the rack to dry.

Passing through the open-plan lounge, they made their way along the corridor which led to Andrew and Natasha's rooms. Opening the door Andrew entered first and threw Toby's overnight bag carelessly onto the bed. Sitting on the edge of the bed Toby took off his sneakers and socks and after removing his shorts and pants he turned to the bag beside him, unzipped it, and began to rummage around inside.

'You needn't bother unpacking now,' said Andrew, 'Leave it 'til later.'

'Yes, all right. I'm looking for my swimming trunks, that's all.'

'Oh you won't need those,' responded Andrew casually, taking off his own shorts and pants.

'What?' Toby looked somewhat aghast.

'I said you won't need those,' repeated Andrew with a grin, 'We don't bother wearing costumes. The pool's so private that there's no point.'

'But ....,' protested Toby.

'It's much nicer going without anyway,' Andrew cut off his friend's argument, 'When you get out of the water you haven't got that awful band of soggy material clinging round your bottom.'

'That's all very well,' responded Toby, obviously unimpressed, 'But if I have to go naked in front of Natasha you know exactly what'll happen to me.'

'Oh nonsense,' chuckled Andrew, 'Anyway, what if it does? Natty won't mind. She's seen you like it before, after all.'

Toby blushed deeply at the painful memory.

'Oh hell,' he muttered unhappily, looking around him as if for a means of escape.

'Here,' Andrew proffered him a towel, 'Wrap this round you 'til you get into the water. Once you're in nobody will be able to see you one way or the other.'

Slinging his own towel casually over his shoulder he made towards the door, followed reluctantly by Toby, who wrapped his towel firmly around his midriff as he went. Going across the courtyard they went through to the pool and Toby was appalled to see not only Natasha but also her mother, both of them lying out on sun loungers soaking up the rays of the midday sun. Hearing the door open, Jackie looked around, and, getting to her feet, she walked gracefully towards Toby, holding out her arms in welcome.

'Hello, hello,' she cried, kissing him warmly on both cheeks, 'How lovely to see you at last. Did you get on OK cycling over here?'

'Er .... yes, fine thank you, Jackie,' he replied, trying desperately to look only at her face and to ignore the fact that she was completely naked, 'It was hot work though.'

'I bet it was,' said Natasha, joining the group, 'I'm baked just lying here doing nothing.'

Toby drank in the sight of the naked mother and daughter standing side by side. One was simply a slightly smaller version of the other and both were breathtakingly beautiful. Despite Andrew's earlier words of reassurance, he could feel a warm sensation spreading through his groin.

'I think I could do with a swim,' he said hastily.

'What a good idea,' agreed Andrew, who was highly amused by the slight bulge that he could see forming beneath the front of his friend's towel.

Without further ado, Toby turned his back on the girls, and, dropping his towel onto the patio, he jumped into the pool.

'I think he's a bit shy,' explained Andrew with a wink.

Natasha laughed and her mother smiled sympathetically.

'He'll be all right in a while I expect,' she said.

'The cold water will help,' chuckled her son, walking to the deep end and diving in.

The four of them swam, dived, laughed, and generally horsed around and Toby could not remember having enjoyed himself so much in ages. His admiration for Jackie Stevenson continued to grow as she joined in the fun with gusto and seemed to be having quite as much fun as the youngsters.

'Goodness,' she cried at last, climbing out of the water and reaching for her towel, 'You've all absolutely exhausted me.'

'Oh Mummy!' laughed her daughter, 'It must be because you aren't very fit.'

'A few more days like this and she will be,' observed Andrew, hurling the beach ball at Toby, who had to jump into the air to catch it.

Natasha climbed up the ladder at the deep end of the pool and left a trail of wet footprints over to the sun loungers. After wringing the water out of her ponytail she shook herself like a dog and laid out in the sun to dry.

'Are you sure you're warm enough like that Natasha?' asked her mother.

'Yes, thanks. It feels even hotter than when we got into the water. What time is it?'

Jackie looked at Andrew's watch which was lying on the table beside her sun lounger.

'Heavens, it's almost lunchtime. I think I can have about fifteen minutes in the sun and then I must go and get us something to eat.'

Lying down beside her daughter she relaxed and closed her eyes.

Tired of their game, the boys got out of the pool and sat on the edge with their feet dangling in the water.

'Having a good time?' asked Andrew.

'Just fantastic,' answered Toby enthusiastically, 'I think the pool is absolutely marvellous.'

He looked around at the limpid blue swimming pool. Surrounded by a patio of warm-coloured stone tiles, it was set within high Cotswold stone walls which gave a most attractive secure sort of feeling to the entire area.

'You seem to be getting on OK without your trunks,' observed Andrew.

'So I am,' agreed Toby in surprise, 'Do you know, I hadn't given it a thought since I got into the water.'

'See, I told you so,' said Andrew smugly.

'It was a close thing at first,' whispered Toby confidentially.

'Yes, I did notice,' chuckled his friend.

'Oh Lord, did Natasha or Jackie, do you think?' asked Toby, looking somewhat embarrassed.

'No, I don't think so,' was the reassuring answer.

Toby looked over at the reclining females.

'My, don't they look lovely with nothing on?'

'Careful,' admonished Andrew, 'You know what'll happen if you start thinking naughty thoughts.'

'I'm not thinking naughty thoughts actually,' responded Toby, 'I was just thinking how right they look. Sort of natural, if you know what I mean.'

Andrew studied his mother and sister.

'Yes, I think I do. Actually, I've decided that girls look sexier in a bikini. It's what you can’t see that makes you curious.'

He leered at Toby and dug him in the ribs. They both roared with laughter.

'What's funny?' asked Jackie, sitting up and looking over at them.

'Toby was just saying that he thinks that naked girls don't look as sexy as girls wearing itsy-bitsy bikinis,' explained her son.

'No I didn't!' denied Toby hotly, 'You said that.'

'So I did,' laughed Andrew.

'I said that I thought you and Natasha looked lovely. Really natural,' said Toby shyly.

'How sweet of you,' responded Jackie, rising from the lounger and coming over to sit beside the boys, 'Andrew's right about girls wearing something being more appealing though. It's the mystery that gives us sex-appeal you know.'

'Hey,' called Natasha, raising herself up on her elbows, 'Did you say something about lunch?'

'All right gannet,' sighed her mother wearily, rising to her feet, 'I'll go and see what I can rustle up. Where shall we eat?'

'Can we have a picnic by the pool?' asked Andrew.

'Yes, but I think it would be a good idea to move the table and chairs into the shade. Come on, lazy bones, come and help me in the kitchen while the boys get things ready out here.'

Natasha got up languidly and followed her mother towards the house.

'Gosh,' said Toby, watching their retreating naked bottoms approvingly, 'You know, summers with the Stevensons just get better and better.'

'It gets even better tomorrow,' chuckled Andrew, 'Emma Knight's coming over to stay.'

'Wow!' breathed Toby, 'How smashing. I like Emma a lot.'

'So do I,' said Andrew, 'Hands off .'

Toby laughed, for he was well aware of his friend's predilection for the gorgeous Emma.

'She's got much bigger knockers than Mummy and Natasha,' said Andrew making crude motions in the air with both hands, 'I bet she'll be worth seeing in her birthday suit.'

'You are coarse,' sniffed Toby disapprovingly, Then: 'Cor, I can't wait!'

This made Andrew roar with laughter and still chuckling the two boys rearranged the patio furniture before going inside to see how lunch was progressing.

The remainder of the day passed by swiftly, spent alternately swimming, playing, and lounging around the pool. Late in the evening, as the outside temperature was still very pleasant, Tom turned on the pool floodlight and all of them went for a 'midnight dip'.

'What a fabulous day,' sighed Toby contentedly as he, Andrew, and Natasha made their way to bed.

'It has been fun, hasn't it,' agreed his friend.

'I'm really into this birthday suit lark you know,' observed Toby, whose self-confidence had grown as the day progressed, 'Apart from feeling super, swimming with nothing on, it's so easy when you come out of the water, for all you have to do is get dried.'

'No messing about with changing,' agreed Andrew.

The youngsters were all still naked after their last swim, for Jackie had taken their towels to dry them in the laundry.

'And best of all,' said Toby, reaching out daringly and patting Natasha's bare bottom, 'Is seeing Natty in the nude. Lovely!'

She turned and gave him a warm smile, evidently flattered by the compliment.

'Do you want to shower first or second?' asked Andrew as the boys went into his bedroom together.

'You go first,' replied Toby, 'I guess I'd better unpack my stuff.'

'Righto. I shan't be long. I'll give you a call when I get out.'

In fact, Toby had already unpacked his few belongings and had reached the bathroom before Andrew finished showering, Sitting his sponge bag down beside the basins, he stood chatting to Natasha as she lay luxuriating in her bath.

'OK, I'm done,' announced Andrew, coming out of the shower cubicle and reaching for his towel.

Toby took his place and yelped as he turned on the water.

'Sorry, I should have warned you about that,' called Andrew.

'Coo, I wish you had.'

When he finished drying himself, Andrew went to brush his teeth, and seeing Toby's bag sitting beside his basin he decided to put the contents away in the bathroom cabinet concealed behind the vanity mirror. He was partway through taking out the contents when he came across an unfamiliar packet.

'What's Durex?' he asked, looking at the slim paper folder with interest.

Toby, still beneath the shower, did not hear the question, but Natasha did.

'It's a type of contraceptive,' she said, 'You know, birth control.'

'Is it? How do you know that?'

'Mummy and I had a chat about it at Easter time. Sorry. I was going to tell you about it but I must have forgotten.'

'Birth control,' repeated Andrew, turning the folder over in his hand, 'How interesting! Toby,' he said in a louder voice, 'Where did you get the Durex from?'

The shower stopped abruptly.

'Hey! What are you doing in my sponge bag?' complained Toby in reply.

'Sorry.' said Andrew contritely, 'I was putting your stuff into the cabinet for you.'

'That's all right,' replied Toby, 'They're for you anyway.'

He turned the shower back on again.

'Where did you get hold of them?' shouted Andrew over the noise of the water.

'Hang on,' responded Toby, 'I can't really hear you. Wait 'til I finish my shower.'

A short while later the water stopped again.

'Umm...is Natasha still there?' came Toby's voice from within the cubicle.

'Yes, I'm here,' said Natasha.

'Then would you mind closing your eyes while I come out?' asked Toby.

Andrew and Natasha exchanged a knowing glance and both laughed.

'Why do you want me to do that, Toby?' she asked innocently.

There was silence from within the cubicle.

'You can come out Toby,' said Natasha, 'Andrew’s is sticking up too.'

As the implications of what he held in his hand had sunk in, Andrew’s penis had become firmly erect.

'Oh,' There was a pause and the shower door slid back slightly, Toby's head appeared around it, 'I feel very embarrassed,' he said sheepishly.

'Here,' said Natasha, who had got out of the bath. She took a spare towel from the rail and passed it through the gap in the screen.

Toby took it gratefully and wrapped it around himself before emerging.

'I asked you where you got these from,' said Andrew, waving the packet of contraceptives at him.

'It was a real fluke,' answered Toby, trying to pat himself dry without removing his towel, 'On the way back from visiting Uncle Peter and Auntie Jane last weekend we had to stop at a filling station for some petrol. I needed a pee, so I went to the toilet and there was a machine. Luckily I had the right money in my pocket, so I bought a couple of packets just for the hell of it.'

'How did you know what they were?' asked Andrew, 'I hadn't a clue until Natty told me just now.'

'Martin showed me one last term. His older brother got hold of it from somewhere or other.' He looked at Natasha with interest, 'How come you know about them Natty?'

'I had a very interesting talk with Mummy last Easter.'

'Oh, I see. I love talks like that with your Mum.'

'Did you say you bought two packets?' asked Andrew.

'That's right.'

'And this one's really for me.'

'Uh huh.'

Opening the paper packet, Andrew removed one of the foil-wrapped condoms and inspected it carefully.

'Have you opened one?' he asked.

'Oh yes.'

'What's inside?'

'It's sort of like a little balloon,' replied Toby, 'But it's made of very thin rubber and it's covered in some sort of slippery stuff.'

'What do you do with it exactly?' asked Andrew.

'Well, it's rolled up, so what you do is to put it at the tip of your peen and unroll it. When your sperm shoots out it catches it. That's how it stops a girl from getting pregnant you see.'

'It's quite simple isn't it.'

'Very,' agreed Toby.

'Daddy calls them Wellington boots,' volunteered Natasha.

'Does he? Why?' asked Andrew.

'Mummy told me that he says they dull the sensations he gets.'

'Does Daddy use them?'

'He used to I think, but of course Mummy’s on the pill now.'

'Oh, yes she is, isn’t she?' said Andrew.

'Have you tried one on Toby?' asked Natasha.

'Er .... yes, I have as a matter of fact.'

'What does it feel like?' enquired Andrew.

'Very sexy actually,' admitted Toby and blushed slightly.

'Did you make yourself come while you had it on by any chance?'

Toby looked at Natasha and his colour deepened. The twins were both most amused by his evident discomfort.

'Oh Andrew, you are so mean asking him something like that in front of me,' said Natasha.

'Nonsense,' contradicted her brother, 'You know that both Toby and I like to make ourselves come. It's nothing to be ashamed of.'

'Well .... yes, I did come actually,' admitted Toby.

'Was it good?' asked Andrew.

'Very good indeed. Neat too. They're super for doing it in bed at night.'

'Have you used more than one then?'

'Two so far,' replied Toby, 'I ruined the first one by trying to use baby oil on it. They don't mix and it sort of melted. What I have found out is that I can rinse them out and use them more than once. They're a bit difficult to roll back up, but if you put talc on them they work quite well.'

'I've simply got to try one,' said Andrew, ripping open the foil of the condom which he was still holding in his hand. He removed the slippery contents. 'Oh, what a strange thing.' He inspected it closely, obviously most intrigued.

'Hold it by the little teat at the end,' said Toby helpfully, 'That's it. Now hold it at the head of your peen. Oh, hang on, you have to pull your foreskin back first.'

Andrew did as he was told and looked at his friend quizzically.

'Hold it in place at the head of your peen with your left hand and then unroll it right to the bottom with your right one,' instructed the expert.

'Isn't it funny,' said Natasha, who had been observing her brother with interest.

'Yes, it's odd,' agreed Toby.

'Here Toby, put one on too,' said Andrew, offering him the packet.

'Oh .... gosh .... no .... thanks all the same,' mumbled his embarrassed friend, looking at Natasha in horror.

'Oh go on,' said Andrew encouragingly, 'You won't mind if he does, will you Natty?'

Natasha giggled and shook her head.

All at once Andrew lunged for Toby's towel and pulled it from around his waist.

'Oh I say!' gasped Toby, standing stark naked before the twins, his penis jutting up rigidly.

'You've got a lot bigger since the last time I saw you like that Toby,' ventured Natasha with a grin.

'Have I?' asked the young man, losing some of his embarrassment at the implicit compliment.

'Definitely,' nodded Natasha, 'You know, I love to see a peen when it's hard. It looks so much more .... exciting. Yes, that's it .... exciting, dangerous, and sexy all at the same time.'

'Wow!' breathed Toby.

Taking the contraceptive packet from her brother, Natasha took out a condom and unwrapped it. Holding the sheath at the tip of Toby's erection she casually unrolled it down the shaft as if she had been doing it for years. At the contact of her hands through the thin rubber, he gave a gasp and realized at once that he was going to climax. A look of ecstasy passed across his face and his penis twitched violently. Andrew recognized his reaction immediately.

'Quickly Natasha,' he said, 'Rub him. He's just about to come.'

Natasha knelt down in front of Toby and encircled his penis with both hands.

'Fuck my hands, Toby,' she urged, looking up at him, her mouth pouting sexily, her eyes sparkling.

He gave a whimper and began to thrust frantically, his penis sliding back and forth in her hands.

'Oh Natasha, .... aah .... aah .... aah .... aaaaah!' he moaned as he experienced a most delicious orgasm.

As he watched, Andrew rubbed his penis vigorously through its feather-light covering. As soon as he saw Toby's spasms begin it set him off too.

'Oh Wow,' he gasped, 'That's it, I'm coming.'

Looking across, Natasha could clearly see the teat on the end of his condom fill with semen.

'Was it a good one?' she asked.

'It was fantastic,' he replied grinning happily.

'So was mine,' added Toby. 'Thank you so much, Natty.'

He slipped the contraceptive off his softening penis and gestured to Andrew to do the same. They went over to the basins to rinse them out and it was not until they had dried them that they realized that Natasha had left the room. Their attention was drawn to the fact by a high squeal from the direction of her bedroom.

'What in the hell was that?' asked Toby, starting violently.

'Oh nothing, just Natty making herself come,' chuckled Andrew, recognizing the familiar sound immediately.

'Oh... My... God,' gasped Toby.

'She usually has more than one climax. Here, follow me, but don't make a sound.'

The two boys crept over to Natasha's door, which she had not closed completely. Pushing it gently Andrew managed to make it open sufficiently to allow them to see the mirror at the far end of the room. In it was reflected Natasha, lying out on her bed with her hand still busy between her legs, as Andrew had predicted. Toby's eyes widened with delight as he watched the delicious sight and a short while later Natasha's bottom rose convulsively off the bed as she had a second orgasm. On she went to a third and then a fourth, by which time Andrew and Toby had regained their erections and were rubbing each other gently in time with her movements.

After yet another climax, Natasha was apparently satisfied for she stopped caressing herself and stretched out sensuously, rubbing her hands up and down her body. Then, all at once, she leapt cat-like off her bed and flung the door open all in one fluid movement. The boys froze, each with the other's penis in his hand.

'Ahah! Caught you red-handed, you ratbags.' cried the girl.

'Holy shit!' gasped her brother, jumping like a startled faun.

He and Toby let go of each other and looked so shocked and guilty that Natasha began to laugh and collapsed, giggling, onto her bed.

'Oh my goodness,' she groaned at last, holding her aching sides, 'If you could only have seen your faces. You looked so funny. Oh dear me.'

She continued to giggle helplessly, wiping the tears of laughter from her face as they trickled down her cheeks.

'That was a very sneaky thing to do, spying on me like that,' she scolded as she pulled herself together.

'Sorry Natty,' mumbled Toby.

'Well,' retorted Andrew defensively, 'You'd have never let Toby watch if we'd asked you. You're such a spoilsport.'

'I might have done,' said Natasha, smiling sweetly, 'You should have asked.'

'Huh,' snorted her brother, obviously unconvinced.

'I'm sorry I made your erections go away,' apologised his sister, because the shock of being caught peeping had been sufficient to quell both boys' ardour.

'I'll make them come back shall I?'

Rolling onto her back she began to caress her body sensuously, her hands creeping slowly but surely toward her crotch. Toby and Andrew watched her with bated breath. Parting the lips of her sex with her left hand, the pretty blonde teenager plunged the first two fingers of her right hand deep inside her. Closing her eyes she gave a sigh of contentment and drew them back out again, she spread the wet sticky liquid that they were covered with over the swollen lips of her vulva. Opening her eyes again she looked at the boys. Both of them bore flaming erections again.

'Now then, isn't that better?' she asked with a little chuckle.

'Go on Natty, don't stop now,' encouraged her brother and Toby looked at her pleadingly.

'You naughty, naughty boys,' she scolded.

'Here, come through into my bedroom, I've got an idea,' said Andrew.

He and Toby went through and he pulled back the bedclothes.

'What are you up to?' asked Toby.

'Mummy put an old blanket on top of the mattress,' explained Andrew, 'She said that we can make as much mess as we like.'

'She is hilarious,' laughed Toby.

'She knows us, that's all.'

Andrew produced his bottle of baby oil from the cupboard beside his bed and smoothed some onto his penis, then handed it to Toby, who did the same. As he did so Natasha came into the room. She looked from one to the other and smiled slowly.

'Hop onto the bed and make yourself comfortable,' invited her brother, 'Toby and I are about to do something very rude for you to watch.'

'We are?' asked Toby, somewhat apprehensively.

Andrew nodded and knelt down on the mattress at the bottom end of the bed. He motioned for Toby to do the same. He did and Natasha, giggling, joined them on the bed. Catching hold of Toby's erection Andrew began to slide his fist slowly up and down. His friend immediately returned the compliment. Natasha giggled again and watched with approval as they caressed each other lasciviously.

'Move a bit closer,' Andrew instructed and the boys shuffled forwards on their knees. Leaning over Andrew whispered something and Toby laughed.

'You're disgusting!' he exclaimed.

'Come on spoilsport, I promised Natty we'd do something rude.'

'Oh all right then.'

Changing hands so that they held their own rampant organs, the boys moved even closer to one another and began to rub the heads of their penises together.

'Ooh,' squeaked Natasha in delight, 'That is rude.'

'We've never done it before actually,' admitted Andrew, 'It feels good though, doesn't it Toby?'

'Mmm,' agreed Toby, holding his hand still he began to thrust gently. Andrew followed his rhythm, and, at the end of each stroke, the tips of their penises touched and rubbed.

'Let's hold them together and do the same thing,' suggested Andrew.

'How do you mean exactly?'

'Sort of make a big fist with all four hands with our peens in the middle.'

'OK.'

The boys did so and began to thrust and rub in unison.

'Oh, this is great,' gasped Toby.

'That's even ruder,' whispered Natasha faintly and began to masturbate as she watched.

'Oh my God!' exclaimed Toby when he saw what she was doing, 'I think I'm going to come.'

'Try and hang on for a little while,' muttered Andrew, 'I'm not quite there yet.'

'I'll do my best,' gasped Toby, 'but I can't promise anything.'

In the event, he gritted his teeth and managed to hold out for another full minute. His concentration was to no avail though when he heard Natasha give a small helpless cry and saw her writhe about in ecstasy as she orgasmed. He gave a moan and Andrew felt his penis begin to twitch, felt the flood of his friend's hot sticky sperm against the head of his own organ.

'Achhh,' he whimpered and climaxed himself, leaning forward and resting his head on Toby's shoulder as his lithe young body shivered and shook convulsively.

Natasha, continuing the short quick movements of her finger back and forth across her clitoris, cried out again as she had yet another orgasm. She fell back onto the bed, giggling and panting.

'Oh my word,' she gasped, 'That was awfully good fun.'

'Wow!' exclaimed Toby, highly impressed by the performance of both Stevenson twins, 'Wasn't it ever?'

'God that was so sexy when I felt your come spurting out,' said Andrew.

'I could feel yours too. Wasn't it strange?'

'Yes, but nice too. Mind you, I don't think I'd want to do it with just anybody.'

'Well you are very special friends,' observed Natasha.

'Very special,' agreed her brother.

'I still wonder sometimes if we're a bit homo,' said Toby, frowning slightly.

'Oh, I don't know,' responded Andrew easily, 'What were you thinking about while we were doing it?'

'Er....,' replied Toby and blushed.

'Making love with Natasha?' asked Andrew.

Natasha looked at Toby and smiled warmly.

'Yes,' he admitted and his blush deepened.

'So was I actually,' said Andrew cheerfully, 'I don't know what that makes me exactly, seeing that she's my sister, but I don't think either of us is really very homosexual.'

Toby laughed.

'Golly,' breathed Natasha, 'Fancy having both of you thinking about making love with me. I'm very flattered,' she gave a small yawn, 'I'm also very tired. I think I'll go to bed.'

Getting up onto her knees she kissed both the boys good-night before slipping off the bed and leaving them with a cheery wave.

'You know she is fantastic,' breathed Toby as she closed the door behind her, 'She's the most terrific sport.'

'Yeah, she's all right!' agreed her brother as the boys straightened out the bed and got into it.

'You both are,' said Toby solemnly, 'I'm so very glad we're friends.'

****

The following morning, Toby was awoken from a deep slumber by a curious rocking motion. He had been in the middle of a dream and consequently felt confused and disoriented for a few moments. As he wiped the mists of sleep from his eyes, he realised that the bed was bouncing up and down beneath him, and, turning over, he found the perpetrator of the strange motion, who was lying on his front thrusting his pelvis energetically against the mattress.

'Goodness, I wondered where in the world I was,' laughed Toby.

'Sorry,' responded Andrew contritely, 'I didn't mean to wake you.'

'Wake me,' chuckled his friend, 'I jolly nearly got bounced out of bed.'

'I do it quite gently at first, but when I get near to coming I'm afraid I get a bit carried away.'

'How near are you?'

'Very near. Will you do me a favour?'

'What's that?'

'Stroke my bottom for me.'

Toby laughed and reaching out did as he was asked. Andrew began to gyrate frantically against the bed and a short while later he buried his face in the pillow and gave a harsh cry as he climaxed.

'Cor!' exclaimed 'Toby enviously, 'That looked super. I wish I could do it.'

Andrew rolled over onto his side and grinned.

'It was fantastic,' he agreed, 'Are you sure you can't do it?'

'Yes. I've tried several times. You know how much the skin stays back from the head of my peen these days. I don't think I'm as sensitive as you are anymore.'

'What a shame. I tell you something that might work though,' Andrew sat up and reached for the bottle of baby oil. Throwing back the bedclothes he spread some onto Toby's penis and then onto his own which was still firmly erect. He got up onto his knees and elbows.

'What are you up to exactly?' asked Toby, somewhat mystified.

'You remember that time that we saw those dogs having a fuck?' reminded Andrew.

'Do I ever,' breathed Toby, 'We could hardly wait to get somewhere private to wank off, could we?'

'It wasn't very private though, was it? The look on that kid's face when he realised what we were doing.'

'Didn't he come quickly too?' remembered Toby, ' He'd hardly started rubbing it when it started to squirt.'

'I thought the funniest thing was the way he ran off afterward. I wonder who he was. I don't think I've ever seen him since.'

'Me neither.'

'Anyway, what I was going to suggest was that you try sticking your peen between my legs and fuck like a dog.'

'You are disgusting Andrew Stevenson.'

'Go on, try it,' he waggled his bottom provocatively and Toby moved behind him and slipped his erection between his legs.

'Cor!' gasped Toby after a while, 'It feels rather good actually.'

'Will you reach round and wank me off at the same time please?'

'Sure thing. Gosh, you're hard.'

It took no time at all for Toby to climax and switching places he allowed Andrew to thrust steadily between the tops of his legs against the crack of his bottom until he too was done.

'Dear oh dear,' chuckled Andrew afterward, 'We've got sperm simply everywhere.'

'It's just as well your Mum's understanding, isn't it,' said Toby as he mopped at himself with a tissue.

'It most certainly is. The old blanket was a great idea.'

Springing off the bed, Toby went to the window and opened the curtains he looked outside.

'I think it's going to be another nice day,' he observed.

'That's good,' responded Andrew, 'I hoped it would be sunny, especially with Emma arriving this afternoon.'

'Gosh, yes!' exclaimed Toby enthusiastically, 'I'd forgotten about Emma coming. That’s super.'

The boys went through to the bathroom and were joined a little while later by a bleary-eyed Natasha.

'Good morning,' she said, stretching and yawning, 'I think it's going to be sunny again.'

'How can you tell?' laughed her twin, 'You haven't got your eyes open yet.'

'You're such a pig,' retorted Natasha, 'I have too.'

'Be warned Toby,' said Andrew grimly, 'This is what women are like first thing in the morning.'

'I think she looks as gorgeous as she always does,' replied Toby staunchly 'You deserve to be called a pig for a crack like that.'

'Ugh,' laughed Andrew, 'You're sucking up to her again.'

'No I'm not,' denied Toby hastily and blushed furiously.

Natasha sidled up to him and reaching up on tiptoe, kissed him on the cheek.

'I think that you’re very sweet and you're to ignore my brother completely I’m afraid that he takes some kind of delight in making you feel uncomfortable.'

'Who, me?' asked Andrew, trying to look innocent and failing dismally.

At that moment both Toby and Natasha moved towards the toilet cubicle.

'Ladies first,' said Toby and stepped back gallantly.

'Thank you, Toby. It's nice to find that there are some gentlemen left in the world.'

'Huh!' snorted Andrew, stung by the intended insult, 'I never think there's much point in being a gentleman when there aren't any ladies about.'

Without bothering to close the door Natasha sat on the loo and peed noisily. Toby was quite shocked by her uninhibited behaviour and when Andrew caught sight of the look on his face he simply roared with laughter.

'See what I mean?' he demanded.

Toby took Natasha's place in the toilet and closed the door modestly behind him. After he had done his business he was followed at once by Andrew.

'If you're going to make your usual smell,' said Natasha, wrinkling her pretty nose daintily, 'Then kindly close the door, open the window, and turn on the extractor fan as well. You don't want to gas our guest.'

'It isn't that bad,' protested Andrew.

'It is too,' retorted Natasha, 'I often think they should have equipped this bathroom with special masks.'

Toby was in fits of laughter as he listened to their good-natured banter.

Natasha washed, brushed her teeth, and then groomed her long blonde hair, Toby stood watching her. Flicking, it back behind her she gathered it up and tied it into a ponytail with easy practised movements. Toby was enchanted by her grace and beauty.

'Mirror mirror on the wall,' he said softly to himself.

'Sorry?' said Natasha expectantly, looking at his reflection in the mirror in front of her.

'I said 'Mirror mirror on the wall',' answered Toby and then blushed again, much to his inner fury.

'You do say the sweetest things,' Natasha blew him a kiss which caused his colour to deepen even further.

At that moment Andrew emerged, closing the toilet door hastily behind him. He caught sight of his friend's suffused countenance.

'What have you been doing to Toby?' he asked his sister accusingly.

'Nothing. Nothing at all,' said Toby hastily.

Andrew looked from one to the other and frowned suspiciously. He went to his basin to wash.

'I suppose we'd better get dressed,' said Toby reluctantly.

'Let's not bother,' suggested Andrew, 'It's plenty warm enough without clothes and we'll be out by the pool soon after breakfast.'

'OK,' agreed Toby with a grin.

'How silly,' giggled Natasha, 'Mummy will think we’ve gone mad.'

Laughing merrily the threesome scampered along to the kitchen.

'Good morning,' cried Jackie when she saw them, 'What's this? Run out of clothes?'

'We thought it was warm enough not to bother with them,' explained Andrew.

'Suits me well enough,' laughed his mother, 'It'll certainly save on laundry.'

After they had finished their breakfast and helped with the clearing up, Jackie sent the youngsters to tidy up their bedrooms. Andrew and Toby made their bed and Toby put away his few belongings, which were spread over the chair at Andrew's desk. Going through the bathroom to look for Natasha, they found her perched on the toilet with a pair of nail scissors in her hand.

'What on earth are you doing Natty?' asked Toby in surprise.

'Trimming my pubic hair,' she replied. 'It's feeling rather long and Emma's always so neat there... I can't have her showing me up.'

'Well I never,' muttered Toby in surprise.

'Yes, I can see you never,' chuckled Andrew, reaching over and tugging at a tuft of Toby's pubic bush. 'It's way past time you did, too.'

'Do you cut yours too then?' asked Toby, astonished.

'Yes, of course.'

'How interesting. I always thought you simply didn't have much pubic hair.'

Andrew laughed and as Natasha got up from the loo and brushed the loose hair from her pubic triangle, he took the scissors from her and began to snip away at himself. Approaching Toby, Natasha bent down and scrutinised him carefully.

'Hmm,' she said.

'Hey, stop it,' protested Toby.

'A little bit off here and there wouldn't hurt you know,' she said, grinning up at him, 'It would improve things no end. After all, you go to the hairdressers when the hair on your head gets long, don't you.'

'I often wish I didn't,' sighed Toby, 'He's absolutely useless.'

'Old Spinks is pretty grim, isn't he?' agreed Andrew, who frequented the same barber, 'Mum keeps promising that we can find somebody new in the city now that we’ve moved.'

'You lucky thing,' responded Toby enviously, 'Let me know when you're going and I'll come too.'

'It's a deal.'

'Toby,' began Natasha thoughtfully, 'Do you mind if I ask you a question?'

'That depends,' replied Toby, somewhat nervously, 'What sort of question?'

'I’m afraid it’s rather personal!' giggled Natasha.

'Oh dear,' Toby looked at her doubtfully.

'It's about your peen actually,' said Natasha.

Andrew looked up from his task and burst out laughing.

'Has this by any chance got anything to do with Emma and that funny conversation you had with her a little while ago?' he asked.

'What funny conversation?' demanded Toby, his curiosity aroused.

'Well you see Emma doesn't have any brothers and we had a long talk about peens recently because she’s very curious,' explained Natasha, 'I think she's going to be really interested when she sees you two in your birthday suits.'

'Oh my!' exclaimed Toby and laughed a little uneasily at the idea.

'The reason that I wanted to ask about your peen is because I've noticed that the head is often uncovered,' explained Natasha, 'Andrew's is never like that except when he's hard and even then it isn't unless he actually pulls the skin back. If Emma notices the difference between you she might ask me about it.

'And you don't want to admit that you don't know why,' chuckled Andrew.

'Exactly.'

'The answer's quite simple actually,' explained Toby, 'You see my foreskin is much shorter than Andrew's and if I pull it back it often stays back, even when I'm not hard.'

'Ahah!' exclaimed Natasha, 'I understand now. I first noticed it yesterday afternoon. It was after you got out of the swimming pool.'

'I expect I pushed it back when I got dried,' said Toby.

'It stayed like it for quite a long time,' giggled Natasha, 'I kept an eye on it.'

'Oh Natasha, you are funny,' laughed Toby.

'It was the same after we swam in the evening and I noticed it again after you came out of the loo this morning.'

'I pull it back before I pee,' explained Toby.

'Do you? Why's that?' asked Andrew.

'It makes it easier to aim at the toilet bowl,' said Toby simply.

'Does it really? In that case, I must try it. Sometimes I miss completely.'

'Horrible boy!' Natasha screwed up her face in disgust.

'I usually pull it forward again if I'm wearing clothes,' continued Toby, 'Because otherwise, it feels uncomfortable. If I'm naked it's quite nice to leave it back because it makes me feel a little bit sexy.'

'Pull it back now,' demanded Natasha.

Toby obliged.

'If I didn't know better, I'd say you were circumcised,' observed Andrew.

'I think it looks prettier like that,' offered Natasha, 'You should always keep it like that when you're bare.'

'Well,' replied Toby, 'I suppose I could, but there is a small problem.'

'What's that?' asked Natasha.

'Because when it feels nice it tends to make me feel randy and when I feel randy ....'

'You go hard....,' finished Natasha, watching him do so before her eyes.

'That's right,' chuckled Toby, looking down at himself ruefully.

'I can see that would be a problem at times,' laughed Andrew.

'Will it stay like that for long?' enquired Natasha curiously.

'If I can manage to think of something else it sometimes goes away quite quickly,' replied Toby, 'But with you standing there, stark naked and actually staring at it, I think it might stay hard all day!'

Natasha stifled a giggle and colouring slightly she turned away.

'Here,' Andrew stood up and proffered the scissors to his friend, 'Have a hack at your pubes with those. I reckon that's guaranteed to frighten any self-respecting peen to death!'

Toby laughed as he took the scissors. He inspected Andrew's groin.

'You went a bit mad if you ask me,' he observed, 'I'm not chopping off as much as that.'

Sitting on the toilet seat he began to snip at himself gingerly and as Andrew had prophesied his erection died away almost immediately.

'Now that looks much better,' commented Natasha after a while.

'You're quite sure about that?' queried Toby.

'Absolutely. We're all neat and tidy now.'

Freshly shorn, the three of them made their way out to the pool. Toby and Andrew prepared to clean it while Natasha settled herself on a sun lounger with a book. An hour or so later the boys professed themselves satisfied, having netted the surface, brushed the walls, and run the vacuum cleaner over the bottom.

'So can I actually swim in it now?' asked Natasha as they stood proudly surveying the result of their handiwork.

'Well,' replied Andrew dubiously, 'As long as you don't take any dirt in with you I suppose it'll be all right.

'She looks quite clean to me,' laughed Toby.

'You never know,' said Andrew going up to his sister and walking around her slowly. Catching hold of her hand he raised her arm above her head and pretended to sniff at her armpit. She struggled to release herself from his grip.

'You horrible person,' she cried.

Undeterred, Andrew bent down and made a show of smelling around her bottom.

'Stop it,' she protested, moving away from him hastily.

She certainly smells all right,' announced Andrew.

Toby, watching the pantomime, was doubled up with laughter.

'You're both loathsome!' complained Natasha, stamping angrily, 'Ooh, ouch, now look what you've made me do,' she cried, raising her bare foot off the patio and inspecting it closely.

'Oh dear, are you OK?' asked Andrew, immediately contrite. He and Toby stopped laughing at once.

Natasha carefully put her foot on the ground.

'I'll live,' she said bravely, 'No thanks to you though.'

'To answer your question, Natty, yes you can swim in it now. In fact, we all can. Last one in's a sissy!'

Taking three quick steps to the side, Andrew dived into the water.

'Let's be sissies together,' Toby suggested and he and Natasha walked to the water's edge.

'One, two, three.' counted Natasha and they dived in simultaneously.

As they lay sunning themselves later in the morning, Toby sighed contentedly.

'This really is the life.'

'Isn't it?' agreed Andrew, 'I'm already dreading the end of the holidays.

'And the end of the summer,' added Natasha.

'Never mind,' said Jackie, who had joined them by the pool at about midday, 'There will be more holidays and lots more summers to come.'

'That's true enough,' agreed Toby philosophically.

'How about lunch?' asked Andrew, 'I'm famished. All this pool cleaning and swimming have given me quite an appetite.'

'All right then,' laughed his mother, 'Just give me five more minutes in the sun, and Natasha and I will go and rustle something up. Where do you want to eat this time?'

'Let's have lunch out here again,' suggested Natasha, 'It's such a nice day that it seems a shame to go inside.'

A few minutes later Jackie rose to her feet and stretched.

'Come on then lazybones,' she said to her daughter, 'Come and give me a hand while the boys move the table and chairs and lay up.'

Lunch over and cleared away, the three youngsters made their way back to the pool. After letting their meal go down for a while the boys decided on a swim, while Natasha continued to be immersed in her novel. It was while they were thus occupied that the pool door opened, admitting a most attractive brunette girl dressed in a minuscule yellow polka-dotted bikini.

'Oh it's Emma,' cried Natasha, throwing down her book and jumping up excitedly, 'Hello Emma! How are you? We didn't hear you arrive.'

'I'm fine,' replied Emma, looking at her friend in astonishment, 'Oh Natasha! You haven’t got any clothes on.'

'Fancy you noticing,' giggled Natasha. She gestured at the boys in the water, 'Neither have they. We don't bother with costumes round here.'

'Well for heaven's sake,' laughed Emma, and reaching round behind her, she unclipped the top of her bikini, 'Why didn't you tell me? I went out and bought this thing specially.'

'Sorry,' replied Natasha, 'I didn't know how you'd take it, so I decided not to say anything.'

'Silly girl,' laughed Emma, calmly peeling off the bottom half of her costume, 'I think it's an absolutely lovely idea.'

Toby and Andrew had watched her casual disrobing with undisguised delight.

'Wow,' breathed Andrew in a low voice, 'She looks even better naked than I'd imagined.'

'She's stunning, isn't she,' agreed Toby, 'I think I'd better try to look somewhere else for a bit or I'm going to have my usual problem if you know what I mean.'

'Likewise,' chuckled Andrew and the two of them promptly duck-dived to the bottom of the pool.

Emma Knight, although only sixteen, already possessed the lush ripe contours of a fully grown woman. Though of about the same height as Natasha, at five feet six inches, she presented quite a contrast to her friend. Instead of Natasha's air of athletic grace, her movements were somehow slower, more voluptuous. Her breasts, as Andrew had already told Toby, were full, round and heavy and they jiggled enticingly as she moved. Her hair, centre parted, which hung part way down her back, had natural chestnut highlights, and with hazel eyes, a neat nose, and a sensuous mouth, which always had the hint of a smile, even when at rest, she was altogether a singularly attractive picture of young womanhood.

Gasping for breath Andrew surfaced and grabbed for the rail at the deep end of the pool. As he blinked the water from his eyes he was greeted by the sight of Emma, squatting by the edge looking down at him with a warm smile. At the view of her intimate anatomy which she was - apparently unwittingly - giving him, his heart missed a beat and he immediately dived to the bottom of the pool again. When he surfaced a second time, to his relief mingled with disappointment, he found that Emma had moved and was sitting on the side with her feet dangling in the water.

'L O M,' he said, tickling the sole of her left foot.

'L O U,' she replied solemnly, joining in the private joke they had, of speaking by using only individual letters of the alphabet and numbers.

'B U O K?' asked Andrew.

'O R, I B O K.' responded Emma. 'B U O K 2?'

'R, I B X...ellent!' laughed Andrew, running out of letters.

'H2o B 82 F,' said Toby, swimming over and joining in the silliness.

'Fantastic,' cried Emma and promptly jumped in.

The remainder of the day passed by quickly and Toby was fascinated by the attention lavished on Natasha's guest by his friend. Andrew was obviously totally smitten by Emma and by the end of the evening Toby realised that the reverse was also true.

'Do you get the feeling that we may as well not be here?' he asked Natasha jokingly as they watched Andrew and Emma laughing together.

'Absolutely,' agreed Natasha, 'But I'm rather pleased about it actually because I love both of them so much.'

'And that’s important?'

'Oh yes! Imagine how awful it would be if he started going out with somebody I didn’t like!'

'I never considered that,' said Toby thoughtfully, 'You two are really very close, aren’t you?'

'Terribly,' Natasha sighed, 'I often think that being a twin is quite a responsibility.'

'I hadn’t thought of it that way,' said Toby, 'But I can quite see what you mean.'

That night the boys and girls shared Andrew and Natasha's bathroom equably and Emma commented upon what a remarkable arrangement it was.

'I never would have thought that I'd feel so comfortable about sharing a bathroom with two handsome naked males,' she said to Natasha, 'It's great fun, isn't it!'

'Yes, it's nice,' agreed her friend, 'But you've got to choose your males with care.'

'Oh Wow,' sighed Andrew happily as he and Toby got into bed after saying good night to the girls. 'I've got to tell you Toby, that I think that Emma is the greatest thing since sliced bread.'

'I'd already gathered that you thought that,' chuckled Toby, secretly thinking that if anything Natasha was even better, certainly as far as he was concerned.

'She is so sexy!' exclaimed Andrew. 'How I've kept myself under control all day I'll never know.'

Impulsively Toby reached out beneath the bedclothes and encountered a firm erection on his friend.

'Oh, make me come for God's sake,' groaned Andrew.

Toby laughed and began to move his hand up and down rhythmically.

'Emma, oh Emma,' moaned Andrew a little later as warm sticky fluid flooded over Toby's hand.

'Natasha, oh my darling Natasha,' Toby cried silently to himself not long after that, as Andrew returned the compliment before they settled down to sleep.

*****

The following three days passed by swiftly as the four young people played, swam, laughed, and joked happily together. Jackie Stevenson looked on approvingly, delighted by the relationship that she could see blossoming between her son and her daughter's best friend. As always a warm comfortable atmosphere existed between Natasha and Toby. Jackie found herself hoping privately to herself that one day a romantic relationship might follow. She was extremely fond of Toby Adamson and thought that he and her daughter were ideally suited, though it was an opinion that she was very careful to keep to herself.
