“So what have you been up to?” I asked my little brother John.

Something about him was making me suspect he’d been spending time with my wilful little sister Lettie and her promiscuous friend Janie Simmonds. I had to be concerned, because he’s too young to be getting mixed up in their mysterious goings-on over the road.

“Nothing!” he claimed, but looking a bit guilty, “just playing with my friends.”

“At Mr Whitaker’s?”

“He’s very nice, Mum and Dad said so.”

That was true. Our parents did like him, even if John was dodging my question. And it was no accident John had mentioned them.

I’d asked if Lettie really needed to be spending so much time over there on her summer holiday project, and if she was really ‘staying at Janie’s’, and they hadn’t wanted to know. They’re too lax with her, I’ve always thought so. She thinks she can do just whatever she likes.

Now John seemed to be going the same way, if his cheeky grin was anything to go by. He’d seen that I had nothing much to go on and he could just fob me off – if I said anything to Mum and Dad they’d just start up again about us all getting on together.

That grin was Lettie’s bad influence!

But anyway I didn’t have any actual evidence so I had to leave it. Still, I had a duty to keep an eye out, obviously. I’ll be eighteen in September and an adult, with responsibilities.

Anyhow the next day my hand was forced. Completely forced.

I’d already spotted, the previous week, young Ella Green from Year 9 going into Mr Whitaker’s drive on her bike, so that was worrying enough: whether her parents were really keeping a close enough eye on her.

Now this time there was another girl with her. I knew her by sight, though not her name. She is a rather distinctive girl, being part Indian or Pakistani by the look of her; or even completely I don’t know. She has rather a glamorous look to her anyway, and some noticeable development already. I can imagine her being a Sky weather girl in a few years.

John had disappeared again too, without saying anything. Mum and Dad were out, so after thinking about it I decided it was up to me to do something and make sure the family was not being let down by my irresponsible younger siblings.

So I went over to Mr Whitaker’s and rang the bell. I had to wait quite a while, then I was rather surprised when it was Janie Simmonds who opened the door! And in a housedress! Did she think it was her house now??

It was quite an immodest way to be dressed, in the middle of the day. In fact had she actually answered the door without underwear? Her breasts were showing quite an amount of detail through the fabric, and her feet were bare.

“Oh hello Vicki,” she said. She smiled, in rather a forced way I thought, but didn’t invite me in.

“Hello Janie,” I said. I wasn’t going to be put off what I’d come for: “I wonder if I could have a word with Lettie, please?”

Janie didn’t want to be rude by closing the door in my face while she went to get her, I could tell, but at the same time she didn’t want me coming in. She hesitated, which made that a bit obvious. There was something secret going on, as I’d suspected, and knowing Lettie...

“Can I come in?” I asked and just stepped in, brushing past Janie into the hall.

“Oh!” I heard her all surprised behind me but she stayed to close the door and that gave me time. I could hear talking and laughing from a door that was open – one Janie had just come through probably – so I walked through into the kitchen, remembering it from my swim in June, and then quickly across and into the swimming pool room ... and there was a scene from, I don’t even know, some perverted top shelf magazine!!

Everyone was naked. Not a stitch on! There were breasts and privates on display everywhere. And there was sex going on!

In the pool were Mr Whitaker – presumably that was why he hadn’t answered the door - the Asian-looking girl and Ella Green. It looked as though the Asian-looking girl had been interfering with Ella - who was floating on her back - between her legs, but she quickly stopped when I came in, and Ella stood up.

Lettie and John were lying on a mat, with a space between them. Somehow I suspected that Janie had been in that space when I knocked! And next to Lettie, I found it hard to believe, was one of our PE teachers from school - Mr Harris! Naked! I hadn’t even seen him arrive.

I placed my hands on my hips. “So!!...”

“I just knew it!” Typically Lettie started talking straight away, cutting me off: “I just KNEW you wouldn’t be able to mind your own business! We’re here having a nice time, in private, and Miss Bossy Boots has to come and stick her nose in.”

Janie had come in behind me: “She just pushed in, sorry.” Everyone was standing up. The three in the pool were getting out.

“I should just think I do have to stick my nose in!” I shot back. “What are you doing with John? And these others, they’re underage too and you’re all having SEX with them! With men. And doing drugs too!”

“It’s none of your business.” Lettie was in my face now. She’s a bit shorter than me but she can really lose it sometimes. She knows I’m a bit of a lightweight too, but I held my ground.

“It IS my business! He’s MY brother too, and you’re all breaking the law: sex and drugs with children, it’s WRONG!” I was looking at Mr Whitaker and Mr Harris.

“Course it’s not wrong.” Lettie’s always so sure of herself, it’s infuriating. “Everyone’s having a nice time, being nice to each other and making each other feel good. John’s not smoking anyway and Ella and Seeta aren’t allowed much, just a taster. Everyone’s ready for sex, who’s here, and just doing what THEY want to do. Not what YOU want.

“John was having wet dreams about Janie so he’s ready and she showed him how to fuck nicely, like David, and Seeta’s ready and having periods and everything and wanted to know about it and girls and so we’re showing her too, how sweet it can be.”

“It’s wrong!” I repeated, feeling myself running out of arguments like I always seem to with her. “Grown men with children, having orgies. You ought to be locked up!”

They all looked pretty shocked at that, except Lettie.

“Oooh yeah!!” Lettie was laughing at me, “just because YOU’RE still a virgin you think everyone else ought to be.”

That was so unfair! “That’s it!” I stormed at them all, as they were starting to gather round me. I suddenly felt it was time to clear out though. With Lettie, she doesn’t back down like other people even when she’s completely in the wrong. But I’d teach her!

“Just you wait!!” I flung at her, turning back towards the door.

“Stop her!” I heard Lettie call behind me. Janie got in the way, then I heard running feet behind me, male feet, and Mr Harris got past me and closed the door. He stood in front of it, huge and naked like some palace guard in a porn movie.

“What do you mean ‘just you wait’?” Lettie demanded, standing there with no clothes on either, as though it was normal. “You’re not going to make trouble are you? Graham would be in deep shit if you told on us, being their teacher. He’d go to prison, even though he’s just here being nice and because I asked him so we’d have a hunk to compare. David would go to prison as well probably.”

I realised I had to tone it down a bit. I’d just wanted to scare her, for once. But she wasn’t sounding scared, she was sounding more like scary.

“No of course I wouldn’t tell,” I tried to sound scornful but even to me it didn’t sound very convincing, “I just think you should stop, as it’s wrong.”

“Didn’t sound like that to me.” I might’ve known Janie would start a double-act with Lettie.

“Jesus Christ,” Mr Harris was sounding really alarmed, “I would go to prison, ‘position of trust’ and everything, with my students, fourteen, fifteen...”

“We wouldn’t tell, would we?” John was looking at Ella and Seeta.

“No of course we wouldn’t,” Ella was quick to confirm it and Seeta was shaking her head in agreement as well.

“Yes I know,” Mr Whitaker was worried too, “but it’s a different thing when you’re down at the police station, just with your parents and everyone’s pushing you to say what they want to hear. They have people trained in it, how to get it out of you. If Vicki tells anyone and the police start asking questions we’re in for it.”

“I won’t,” I hated backing down but I had to, “it was just to scare Lettie. I think it’s wrong but I won’t tell anyone.”

“How do we know?” Janie’s a sweet girl normally, even being a complete tart, but she’s such friends with Lettie she’ll do anything if she thinks Lettie’s being threatened. They’ve been friends since playschool and are joined at the hip. Other parts too, half the school thinks!

“You have to join in,” Lettie had decided. She can be so like that. “You have to join in and be part of it and we have to film you so you can’t tell anyone for absolute certain sure. You’re almost eighteen so some video of you forcing Seeta or Ella would drop you deep in it as well.”

“Forcing?” Mr Whitaker and Mr Harris said almost together.

“Well not really,” Lettie seemed to think that was obvious, “we just have them tied up or something so it looks like forcing on the video. Assuming you’re up for it?” It finally occurred to her to consult the girls, “it’s pretty vital.”

Ella and Seeta nodded. Obviously they were quite corrupted already.

“Dream on,” I said. She had to be kidding. “Me part of your orgy? I don’t think so!”

“Well it’s your fault,” Janie chimed in again, “you came and pushed in so now what do you expect? It’s just been nice up to now. Nobody asked you to come and find out and spoil everything, and now you have so we have to be sure you won’t say anything.”

“I hadn’t realised,” said Mr Whitaker, “it’s all seemed so natural and harmless, but really now we have to take it seriously, I’m afraid.”

Lettie had sucked him into it, one way or another. She twists everyone round her little finger.

“Well you’ve got my word so that’s it. That’ll have to do.” I tried to push past Mr Harris to the door but he kept moving to block me.

“I’m sorry Vicki,” he said, “but you have to see it from our point of view. It’s a serious risk, something that could ruin my life and David’s. You just have to go through the motions for us, that’s all.”

“No WAY,” I struggled with him but he’s a million times stronger than me.

“It won’t hurt,” Seeta tried to reassure me. It wasn’t what I wanted at that moment, to be patronised by a trainee lesbian in her birthday suit.

“Shut up!” I said. I was being manhandled by a naked man and my manners were suffering.

“Oooh,” said Ella. That was all, but it was enough to tell me they were all together against me. John hadn’t said anything to support me.

“Bring her over,” said Lettie.

This whole thing was HER. I remembered her talking to Mr Whitaker all that time at the party back in June - she must’ve been plotting it then even. In fact had she actually suggested the party in the first place?

Mr Harris is so strong. He does weights and everything, and all sorts of exercise with being a Physical Education teacher. He’s all rippling muscle, and he must be six foot. I only weigh forty-four kilos, so he could move me around without even being rough. He gripped the tops of my arms, not hard, and just manoeuvred me onto the mats that were all over the floor between a hot tub and a big TV on the wall.

“Right then,” Lettie sounded in charge even of our muscle-bound thirty-something teacher, “sorry Vics but you’ll just have to do a bit so we can film it.” She didn’t sound sorry.

“Clothes off,” she instructed. How she has the nerve to call ME bossy I don’t know.

I just stood there. I FOR SURE was not going to strip on her say-so!

“Here let me.” Janie Simmonds moved towards me, the skank, wanting to take my clothes off! She’d taken off her housedress for some reason, revealing her freckled skin with a slight tan all over.

I could hardly believe what was happening as Mr Harris held me while Janie started undoing my jeans!

“Don’t you dare!” I felt so helpless and humiliated. “You’re just making it worse.”

“Worse?” Lettie latched onto it. “Worse how? Like what you’re going to tell everyone?”

“No! NOOOO!” was all I could say as I kicked and struggled. But I couldn’t stop Janie pulling my T-shirt up!

Mr Harris forced my arms up, Janie pulled my tee up over my face, and then in a moment he’d let go, she’d pulled the T-shirt right off and he’d got hold again. I was in my bra with my jeans undone, and Janie was already pulling at those!

“Nooo!” I kept going, more of a gasp than a shout by now as I was struggling like mad. I pushed my knees apart so she couldn’t slide the jeans down, but she’d got them started and I could feel my panties being dragged down with them.

“Go on Vicki,” she was saying, “just join in a bit, everyone else is nude, it won’t do any harm.” She kept pulling for a bit but she couldn’t get them any further with my legs jamming them. Ha!

She slid a hand in through the open zip and molested me!! Her finger slid right over my bits!! I closed my legs, automatically, and that was what she’d wanted, the lezzie tart, she had my jeans down at my ankles in a flash! And my panties were half-way down my ass.

Mr Harris lifted me up, right off the floor, and Janie started pulling my trainers and socks off, which I couldn’t stop her doing at all - my kicks went nowhere with the jeans bundled up down there. Then she pulled my jeans again and they just came off.

Everyone else was standing looking as I was forcibly stripped! I was down to my bra and half-off panties.

They didn’t last long either. Mr Harris made space for Janie to undo my bra catch then she pulled the straps down my arms, and like before he slid his hands down my arms a bit, let go and took a fresh grip, too fast for me to do anything. Janie tossed my bra onto the floor with my other stuff.

No-one had seen my tits, ever, apart from in the showers when it’s different. Though boys certainly want to! Janie stood back to look, the cheeky baggage, and everyone else stood perving, apart from Mr Harris who was peering over my shoulder at them. I could feel something on my back I was pretty sure had to be his ... thingy!! I’d always thought he was a bit lustful about me.

“Oooh lovely,” Janie was taken with them by the sound of her, though they’re not that big: I’m a 30B that’s all. “SUCH a lovely shape!” she carried on, “so pert, and so high. Are they sensitive?”

And she touched one!!! She moved to the side of me and started stroking over it! I could feel her tit on my arm as well, her nudity right next to me.

“Get OFF!” I said, struggling again.

“Do you think we ought to be, er, touching her up?” Mr Whitaker came to my rescue.

“Oh, I suppose not,” Janie giggled, taking her hand away, “sorry Vicki I got carried away. Your body is so gorgeous you know. I’ve always thought so.”

“Thanks a bunch,” I snapped sarcastically, “that means soooo much to me.”

“Well it’s a bit of a waste,” she wasn’t even slightly withered, “keeping it to yourself when you could be making people happy with it, giving pleasure. It looks made to make people cum. Or even just look at. It’s a model’s body really, just a bit shorter.”

“Cum??” I was shocked, “it’s for me to live in, not for sex maniacs to perv over!”

“Well I think it’s very nice.” Ella Green was staring at me.

In the back of my mind I couldn’t quite stop myself thinking that Ella Green saying that, with her looks and figure, did make it a bit of a compliment.

“Anyway let’s have these off,” Janie took hold of my panties, “though they do look rather sexy half-way down.” She started pulling them down and I opened my knees to stop her.

She grinned up at me. “Do you want me to stroke your pussy again? I don’t mind.”

I hastily closed my legs and in a second I was completely in the nude. Mr Harris let me go and I took a step away from him. I saw everyone’s eyes go from me to him.

I looked round. He did indeed have a disgusting aroused man thing sticking right out. It jutted up, waving around slightly. It was the first one I’d actually seen. I hadn’t been expecting my first sight of one to be on my own teacher!

“Sorry,” he did at least apologise, “it’s the contact.”

“And holding me while I get stripped naked!” I spat.

“Well Vics,” Lettie had been quiet for too long already, “it’s just a natural reaction. Fact is you are rather gorgeous, you know. In fact if you weren’t my sister...”

“Oh great!” I snapped, “Lettie Mellors would do her pervy thing with me if only I wasn’t her freaking sister! That makes me feel SOOO warm and fuzzy inside.”

“Well it’s nice to look nice, don’t you think?” Seeta wasn’t going to stay shut up. “If you’re going to be doing me on video then at least...”

“Yeah,” Ella joined in, “if the video did get out then at least it’d be hot!” She giggled, nudging Seeta next to her.

God! The awful plan came back to me. It was fun to them but I’d never done anything and I was NOT a les. Sex was something for life partners anyway, that was my view.

“Well let’s get arranged,” Lettie was focussed on my downfall, “who’s it going to be?” She looked at Ella and Seeta.

“Me!” They both said together, then looked at each other and laughed. They were competing for it!

“Let’s start with Ella,” Lettie said, looking at her, “as you’re a bit more experienced and you cum so nice and easily. We’ll make it up to you after, Seet. What can we tie you to Ella?”

They all looked around. I couldn’t help thinking there was a bit of enthusiasm building up.

“Pool steps,” said Janie, “and some cushions under?”

“Mats,” said Mr Whitaker. I noticed his appendage was looking bigger than it had been, even if it was still dangling. I had a sinking feeling his protection was wavering. He was looking at me rather like Mr Harris was!

And so was John, the little beast. And his little willie was sticking out a bit as well!

They moved the mats over to the pool and folded one in half to make a pile a foot or so high. Ella lay on them on her back with her knees over the edge and her arms over her head. Mr Whitaker went into the house and reappeared with some ties. Formal neckties. I nearly told him he was going to ruin them, but just stopped myself in time.

Lettie and Janie tied Ella’s wrists to the handrails of the steps, then tied two ties together for each leg and led them round to the base of the rails. It looked as though they were holding her legs open, even though they probably weren’t really.

Anyway there she was, the fourteen-year-old school beauty: small, blonde and helpless, ready to be ravished. It was hard not to stare. She was tanned all over, every inch. I tried not to look at her little blonde bush and her girly bits, but they kept drawing my eye. But anyway I wasn’t going to do it.

“Forget it!” I said, shaking my head, “I said I’m not going to and you can’t make me.”

“Well you’re not going until you do,” said Lettie.

“You have to let me go sometime,” I pointed out. “I only have to wait until Mum and Dad wonder where I am, and then how long before they wonder about here?”

There was a silence while they realised I was right and they couldn’t actually force me to abuse Ella. I felt a huge rush that I’d beaten Lettie, the little madam!

But I should’ve known, really, that with her when you think you’ve won you’ve probably only raised the stakes.

“Alright well you’ll have to be the one that cums then,” she said, motioning to Mr Harris with her head. “You cumming with Ella and Seeta playing with you will do just as well: you won’t want that all over school will you?”

While the awful meaning was sinking in Mr Harris grabbed me again. I couldn’t think of anything to say to stop them, just weakly ‘stop, no,’ and they took no notice! If I complained or threatened Lettie’d just say it proved I was going to tell!

In a moment Ella had been untied and I was on my back being tied in her place!!

Next thing I was as helpless as young Ella had looked. And I’d been wrong about the leg ties: they tied them just below my knees and they did totally stop me closing my legs. My most private place was completely exposed and vulnerable.

And Mr Whitaker had helped! So no rescue from him now. John was just watching. Well he’s always had a thing for Lettie even though I’ve always loved him too. Actually now I looked again it rather seemed like he had a thing for me after all, but not in an appropriate way!

“OK we can make this a lesson, as it’s Seeta’s first day,” Lettie was still bossing everyone about, but they didn’t seem to mind. “Do you want to give her a demo, Ella?”

I watched as five of them came together in a line looking at me: Mr Whitaker, Janie, John, Lettie and Mr Harris, all intent on my tied, naked body and having a great time by the look of it, while Ella and Seeta closed in on my pelvic region.

Nobody had ever touched me there, since I was a baby and I couldn’t remember that. I had my pride though. I wasn’t going to plead and give my bossy pervert sister the satisfaction. I just wouldn’t respond. That would teach them. They’d get fed up and untie me, and I’d put my clothes on and walk out in dignified silence.

Ella put a hand on my bush! I stopped looking and lay my head back. I’d concentrate on not responding.

“So we can just comb her bush a bit, to start with,” I heard Ella, all fourteen years and five feet one of her, start giving her lesson to her eager pupil. “Just very lightly, fluff it up where it’s been squashed by the panties and then comb our fingers through it.”

It wasn’t too bad. It was a novel sensation to be honest but nothing to get worked up over.

“Now we just lightly brush over it, just like to tickle it, touching the ends.”

I could almost imagine if it had been the love of my life doing it, I’d have enjoyed it. But it was alright.

“OK now we just run our fingers down over the hood of her clit, like this.”

I jumped. It was impossible not to.

I saw the lights go on and heard movements. I looked up to see Lettie and Janie pointing their phones at me.

“I’ll do video shall I?,” said Lettie, “and you do photos?”

“OK,” said Janie. They were both grinning like Cheshire cats. I lay back again, ignoring them.

“So you run your finger down,” Ella continued, demonstrating, “just lightly, feeling with your fingertip, then on the way back up you rub a bit harder and lift this little hood back a bit, see?”

I couldn’t quite keep still, with what it felt like. I realised this must be what ‘playing with yourself’ involved, but I’d never done it. I didn’t want to be that kind of girl. And I still didn’t!!

But I wasn’t going to beg. I knew Lettie anyway: she was set on making me ‘join in’ with her depraved orgy and she wouldn’t stop just because I asked. All I could do was not react, and run time off the clock until she had to give it up.

“OK you do it for a bit,” Ella was giving her pupil hands-on practice. I concentrated on the roof while Seeta’s small finger rubbed up and down my private places. It went on for a minute, and it was weird, but I just about managed to block it out.

So far, so good.

“OK so now we’ll go the next step, in her pussy!” Ella sounded quite keen.

I sensed a shuffling as the rest of them moved closer to my exposed private area. No doubt the whole perverted lot of them were thinking of it as a ‘pussy’ too.

“So you run your finger down again,” Ella continued, “but this time when you get to here you feel for the hole, where it is, even though it’s closed, and run your fingertip round it. Then if it’s still dry you lick your fingertip and do it again. And just keep going until you can get your finger in. Have you been doing yourself?”

“Oh yes,” Seeta seemed to think it was an odd question, “for ages.”

“OK well it’s the same obviously, so just go round it, and play with her clit as well, use a bit of spit, you know, till you can get a finger in, and then just do the things you like, but to her. Feel for her G spot and everything.”

So Seeta lined up her little finger and pushed it in! Just like that. She didn’t seem to worry about it at all.

Then she started doing things that I really wasn’t prepared for. It went all zingy inside. I’d never felt anything like it! Suddenly it was wet down there. My bean was sensitive, like some sort of button that had squirted a drug into me! An amazing drug! The blood was rushing through my head, it felt like!

I groaned and writhed about, I couldn’t help it, it was like I’d been plugged into an electric socket. I was gasping even. The sensation got stronger and eventually I had to look: I could only see her thumb and little finger. She had THREE fingers in me!! I looked, up, mortified at what my perverted audience were viewing.

Lettie and Janie still had their phones on me. The men and John were ALL playing with their male equipment, which looked completely stiff. I looked at them but they didn’t care; even my own little brother, even my teacher, and even my sixty-five-year-old neighbour!

They were all in shape, I had to admit, and Mr Whitaker and Mr Harris would be quite hunky to the likes of Janie I daresay, and looking rather tanned and fit. Still I was horrified that they were getting to ogle me like this, being so outrageously taken advantage of and my body actually responding to the abuse!

Everyone was was grinning at me, Seeta was earnestly molesting me internally, and my pervert sister and her sex-mad friend were smirking as they recorded my helpless arousal.

It went on and on, for ages. But although I was trembling and writhing and gasping, I didn’t orgasm. I was wet, and I jerked about and gasped a lot, pulling on the ties, but I didn’t climax! Whatever a climax was, but I knew I hadn’t had one as my feelings hadn’t had any sudden change - they’d just gone up and up and then on and on.

In a while Ella had a go, and then Janie, who got me really close but still I didn’t go over the edge. I could feel the edge was there, sort of thing, but I never let go that last bit that would’ve given my depraved sister her victory. I just zinged, near the cliff but not quite going over into the abyss she was planning for me.

After what felt like half an hour she put her phone down. “OK let’s take her off there and spread her out. Let’s put the mats back and carry on over there.”

When they got me up I realised I was tired. I staggered a bit and Janie put her arm round me. “Are you OK?” she asked.

I leaned on her a bit. I was a little confused, after all the blood rushing through my head. My body was tingling all over, and I was feeling a bit shaky.

She propped me up while the others spread out the mats. She’s a kind person even if she is easy. She got me to lay down and then lay down next to me. Her leg was touching mine but I didn’t bother about it. Ella lay down on my other side, so I could feel a warm body each side of me.

“OK let’s have a look.” Lettie was opening a laptop like it was hers, though it wasn’t.

She turned the TV on and fiddled with her phone and the laptop. A picture appeared: the start of a movie. It was starring me! Nude, tied to the pool steps with my legs wide open and my private area right in the middle of the screen. I tried not to look but I couldn’t help peeking.

Lettie started it playing and the sound came out of some big speakers. My gasps echoed round the room.

The picture was wobbly but it did show me being interfered with by two totally underage girls. It zoomed in to between my legs, showing it all glistening and looking a bit swollen, and the little fingers abusing me, then zoomed out again. My gasping got worse. Christ!

Would it satisfy them? I certainly would NOT want this going viral!

Lettie seemed to be worrying about it though.

“It’s sexy,” she was saying, “but we can see who Ella and Seet are, so that won’t do. My fault. And she doesn’t cum, that’s obvious, so it’s like limited really how much she’s a lezzie enjoying underage girls. She could say it was forced and people would believe her.”

“That’s because I’m NOT a lezzie!” I squeaked. It was going to be a shout, but it didn’t come out right because Janie had just started on me again! Her fingers were between my legs, with her knee between mine.

What’s more Ella had started stroking my right breast. I realised they’d left my tits alone before, but it was getting a bit tingly as she stroked her fingertips over it!

I didn’t try and fight them off. I knew I’d just be overpowered again. Anyway I was starting to feel a bit used to it, crazy as that must seem I know. I just lay there being played with, gasping again and feeling the blood rushing through my head. I’d let them get bored and then leave.

It was a bit different now though, with two experts instead of one and a trainee. And with them lying next to me they could kiss my neck, lick my tits and actually nibble my nipples! All the time with their fingers in me and on my bits and everywhere.
