Santa's Little Helper Ch. 03

Author's Note: I received more comments and votes on Chapters 1 and 2 of this story in 3 months than any of my other stories, with the possible exception of Uncle Bob Chapter 1. It'll be some time before Chapter 4 emerges, as I'm pondering the plot direction - suggestions welcomed - and I have a few other stories to complete, but I hope you enjoy this.

"Last Christmas, I Gave You My Arse"

The following day - Boxing Day - I composed an email to Mike Wallace, the senior police officer in charge of child protection. Mike and I had met at many child safety committee meetings when we'd discussed vulnerable or disturbed kids who needed multi-agency support. Sometimes I'd call Mike about a kid who'd run away from a home that I was managing, or Mike might call me to see if I had any capacity to take some vulnerable runaway that he felt would benefit from my care. This by-passed some of Social Services' processes, which wasn't ideal, but if he had a scared kid in a police cell, he knew he could count on me to either find an emergency place for them or at least to be able to pull a few strings to get the kid somewhere safe and appropriate as soon as possible. We had a very good working relationship.

So I WhatsApped Mike to inform him that I'd become friends with Nina and that she was alleging that her stepfather - a guy called Gerry Pascoe - had not only tried repeatedly to do inappropriate things with her (she wouldn't say precisely what) but that he might well be planning similar behaviour with Nina's sisters. I asked him to make discreet enquiries about the stepfather and let me know in case I needed to do anything, but not to send the 'heavy mob' in until Nina was ready to make her allegations formal. Mike would still be on Christmas leave, so I said that it wasn't mega-urgent but that I'd like the stepfather investigated soon to avoid any further potential abuse.

Nina called her mum, who told her to come home and insisted that her stepfather was innocent and was just trying to be friendly. Nina pointed out that being slapped hard in the face and called a bitch wasn't her idea of friendly gestures. She said that she wanted to think about things for a bit before returning home, and assured her mum that she was 'very safe' - a phrase I liked. Then she phoned Gemma and asked her about their stepfather. Gemma felt less safe at home without Nina there, but it seemed my little talk with her stepfather had put him on at least tolerable behaviour.

So Nina and I spent some time being affectionate - kissing and cuddling, moving on to mutual masturbation and then oral sex in sixty-nine. I felt that having my cock spontaneously stroked and then sucked by Nina, while I first stroked and then licked her pussy, was a far better way of spending Boxing Day than watching repeats of Die Hard 3 on the telly.

We'd kept meals simple and light, because our main aim was to eat each other. Sixty-nine isn't always a great position; her tongue is the wrong side of your cock for a start, and if her clit is over your tongue, you don't have much room to finger-fuck her. But hey, we coped. Because it almost doesn't matter where her tongue is if the top third of your cock is in her throat. And if she can't be finger-fucked in the normal hole, because she has a hymen, you can work your arm around and get a finger up her arse with a bit of judicious flexing.

And the great thing with non-penetrative sex - that is, not up the pussy at least - is that it doesn't matter if the guy comes first. He can continue to stimulate the girl even after spurting a pint of cum down her gullet. Which is precisely what happened. It was very satisfying to feel Nina's orgasm with my finger up her bum and my tongue on her clit, having unloaded into her hot, wet and deliciously sexy mouth. This was turning into the best Christmas I'd had since Celia died.

After cleaning up and a light lunch, we spent some time researching anal sex online; the ins and outs of it, so to speak. We needed to know about tools and techniques, how much preparation was required and how to go about it, how to know when it was working and when it was hurting; what to expect. There was a surprising amount about it on the Internet, and Nina was as fascinated and excited as I was. After working out what we wanted to try, we went onto a couple of online sex shops and looked at all of the toys, lubes other likely-looking items. Nina helped me choose the things she felt would be right for her, so we ordered them and waited for delivery.

It was a cold but bright day, so we went for a walk.

"How's it been for you?" I asked her as we strolled along.

"What?"

"Christmas with an old fart."

She turned to me, smiled - and kissed me. She linked her arm through mine as we walked on.

"So much better than I could ever have imagined," she said. "You've been so kind to me, Frank. Christmas at home would've been half boring, half terrifying. My stepfather seems to think that what he says, goes. So we'll end up watching what he wants on telly, eating when he wants - with my mum doing all the cooking and clearing away - and not saying anything that might offend him. Gemma and me, we'd try to keep out of the way, because he would be inappropriately affectionate or unnecessarily rude to us, depending on how drunk he was. Lily's always sad because she's never known a Christmas like when my dad was alive. Little George is too young to know any better, but Christmas is meant to be about kids, and my stepfather seems to think that, as he's the biggest kid around, it should be about him."

"Does he give you presents?"

"Hah! My mum buys them, mostly out of her own money. As he takes a lot of that, there's not much to go round. I don't mind for me, but Lily and George deserve better. Mum won't hear a word against him, but he's a total arsehole."

I stopped and put my arms around her. "Let's see what we can do. If we can find evidence against him, we can maybe put him where he probably belongs."

"The trouble is, Mum would be heartbroken. She's lost one husband she loved - we all loved him - and fell for the first man who told her she still looked nice. Except he's a user. I don't mean drugs; I mean, he uses people. And he's lazy and violent and nasty. But I'm sure he has some good points - just none that I've seen."

Later, after a light supper, we made love again. I spent around half an hour focusing purely on Nina's pleasure, teasing her skin, stroking and massaging. I licked behind her knees and up her thighs. I stimulated her breasts and her nipples, stroked across her abdomen and traced the outline of her hips. When my fingers told me her slit was wet enough, I made it wetter, exploring each little crevice and curve with my tongue. I rimmed her puckered arsehole, making her giggle at first and then push back against my mouth as the sensations became more erotic. I stayed there, my tongue lightly probing and strumming the crinkled hole, while I used my finger on her clit. Her moans increased in pitch and volume until she was writhing around and moaning in orgasm.

"You don't need to," I said as she stroked my cock and bent her head towards it after her climax had subsided. "I just made you come because I wanted to. There's no need to... OOOH!"

Nina's mouth was extraordinary. Where Celia's blowjobs were nice, Nina's were naughty. I mean filthily naughty. Her lips and tongue had this lascivious quality about them, the way she would lick up and down my shaft, nuzzle my balls, run her half-open mouth along the side of my cock, then suck hard at its head. She would fuck the tip using the grip of her moistened lips, almost as though she was trying to force a virgin pussy or arsehole over it and it was too big to go through the hole. Then she would open wide, take in most of my length, swirl her tongue wetly around it and slide it in and out, in and out until, finally, she pushed her head down until her nose was buried in my pubic hair and my cock was encased in her tight, wet throat. And she wouldn't stop until she'd milked a load of cum out of me.

Quite how she did it - or even why she did it - was a mystery to me. I was just extremely grateful that she wanted to do it.

On the 27th, I got a message back from Mike, saying that he wouldn't be back in the office until after New Year, but that he'd messaged the guys on duty to check to see if the stepfather had any criminal record and to let him - and me - know if there were any developments. I drove Nina home - we stopped around the corner from her house - so she could see her mum and siblings.

"I'm going to stay here tonight, but I'll call if there are any problems," she said before she kissed me and got out of the car. I texted her later that evening.

"Everything OK?"

"Not too bad. Gemma, Lily & George pleased to see me. We're playing UNO in my room, keeping away from Gerry. Mum happy I'm home. I'll call tomoz. XXX."

I liked the 'XXX', but not the fact that we wouldn't be together that night.

The following day, the package arrived from the sex shop. I looked at the devices and thought they looked a bit brutal. I decided to try out the plug and the anal dildo on myself, not as a sexual thrill but to reassure myself that, when Nina used them, they wouldn't hurt her. I also needed to know how much lube to use, and whether the advice about relaxing and 'pushing out' would work. The result was 'satisfactory'. I can't say I derived much actual pleasure from the experience, but it didn't hurt. It felt a bit weird and, if I'd persevered with using the vibrator against my prostate, I may have got a thrill from it, but it wasn't painful. I just hoped that Nina would find it more exciting than I did.

That evening I texted her again and she called me back.

"I'd like to stay another night, Frank, if you don't mind. Gerry's getting drunk and I'm worried that he might try something with Gemma or Lily. I think he now realises that I'll cut his dick off if he tries it on with me. I'll call you in the morning and if it's all quiet tonight, I'll come back to yours tomorrow."

"That's fine. Do what you feel is right. And by the way, the stuff we ordered has arrived, if that helps you decide."

"Frank, you're a dirty old man."

"And you're a very naughty young girl. Is that a problem?"

"Not at all, Frank. Not at all."

The following morning, Nina called around 8:30.

"Frank, could you please come and collect me? Gerry and me have had a huge row. He tried to hug me, pretending to be affectionate but just hoping for a grope. I told him to fuck off, he hit me, and then it all kicked off. Anyway, Mum doesn't want me around. She won't believe me when I tell her what Gerry's really like. Gemma's trying to keep a low profile, but I've told her if she needs help, she has to call me. But Gerry's sulking and shouting, and as it's me he's pissed off with, I should get out of the way. I'll see you at the bus stop; best you don't come to the house."

I went straight out to the car and drove around to where Nina lived. She was standing at the bus stop, holding an overnight bag and crying.

"I just wish Mum would open her fucking eyes!" she sobbed when she got into the car and I leaned over to hug her. "She thinks the sun shines out of his arse when really his arse is all there is of him."

I took her home, gave her a glass of wine, cooked us some pasta and held her while she told me about Gerry's temper, the way he was when he was drunk and the way he treated her, her mother and siblings. I felt an overwhelming desire to go round to her house and thrash the living daylights out of her stepfather. Instead, I hugged Nina and, when she'd stopped crying, sent her off to have a shower and get into bed.

I cleared away and, when I heard Nina come out of the bathroom, I went up and showered myself. When I came out, Nina was in bed; my bed, or, since she'd arrived, our bed. There was a soft buzzing noise.

"Feels weird, but it's actually rather nice," she said.

"What are you trying?" I'd left the package on the bedside, and I could see that she'd extracted the lubricant and opened a couple of the boxes.

"I - I've inserted the vibrating plug. It feels - ooh - rather sexy. It's sending vibrations up inside my bum and through the back of my pussy. Then I got one of the vibrators out and started using it on my clit. I think, if I carry on like this, I'm going to come. Would you like to help?"

Would I? I pulled back the duvet, climbed into the bed, put my arms around her and kissed her. She felt small and vulnerable in my arms - and delightfully sexy. I licked and sucked her nipples while teasing the entrance to her vagina with my fingers. The expression on her face and the soft moaning noises she was making told me I was doing the right things. Then I slid under the covers, took the cock-shaped vibrator from her hand and positioned it at the entrance of her vagina.

"Don't - don't push it in!" she said breathlessly.

"Don't worry baby," I replied. "We'll leave it there. I just want to do this." I leaned in and gently licked around - but not on - her clit. She squealed and wriggled. I stayed focused, gently lapping away, exploring the nearby folds with my tongue, feeling the weird vibrations. By now she was moaning quite loudly. I tried to avoid making too much contact with the orgasm button, preferring to tease around it, prolonging the build-up and postponing her climax for as long as possible.

But by the way her hips were bucking, I could tell she was very close, and if I didn't want to lose the moment and reduce the intensity of the orgasm, I had to ensure my timing was just right. A final circuit around her oversized clit with my tongue tip made her cry out. There was so much fluid around that it was wetting the sheet. I decided.

I gently pushed the tip of the vibrator inside the entrance of her vagina. She shrieked.

"No! Careful, don't..."

And then I captured her clit between my lips and strummed the tip with my tongue, with one hand holding her abdomen to stop her bucking and writhing too much. Her squeals and moans told me everything I needed to know. While my mouth was doing the necessary work, I was conscious that I shouldn't let the vibrator penetrate too far inside her as she wriggled around in the throes of a powerful orgasm. It was tricky, but I'm not without some skill.

When she finally collapsed onto the bed, begging me to stop, I carefully withdrew the buzzing phallus to remove the risk of hymen damage but kept her clit captive between my lips. She clawed at my hair to try to get me to stop - and then exploded into a second, even stronger orgasm. After which, I was prepared to grant her some mercy.

She arched her back and removed the buzzing plug, dropping it beside the bed. I could still hear its soft hum over Nina's ragged panting.

"Fuck, Frank - that was - that was insane! I - think I came - from my bum! I didn't know I could do that."

"Anal orgasms are supposed to be very intense," I said, having read up on the subject while Nina was at her mother's house. "There's also allegedly this thing called a 'trigasm', where the orgasm comes simultaneously from the anus, the G-spot and the clitoris. Again, some women who've experienced it say it's very intense."

"Well, if it's more intense than the ones you've just given me, I think my body might explode. Fuck, Frank - you're an artist!"

"I've been called that before," I replied. "Usually preceded with the word 'piss.'"

"Do you think - do you think that I could get an orgasm from just - just getting fucked?"

"In the pussy or up the arse?"

"Well, either. Did - sorry, I hope you don't mind me asking, but - but did your wife come when you - when you fucked her?"

I thought for a moment. The memory of making love with Celia made me momentarily sad. "Well, yes, but I was usually doing things with her clit or sometimes her nipples at the same time. I used to try to hit her G-spot with my cock, but as you know, I'm not particularly big."

"Big enough for my bum, I think," she said with a saucy smile.

"Naughty girl! But you see, once the vagina has relaxed, it expands to receive the guy's penis. If he's big, it's easier to keep up the G-spot contact. If he isn't, then in the heat of the moment, you can lose the angle and miss it more often than you hit it."

"I - I guess I'll be very tight, the first time. Maybe it'll feel good when I finally do it."

"Well, I suggest you break that pesky hymen first. I've had to comfort quite a few teenage girls who've decided to lose their virginities with a callous or inexperienced guy, and they said it hurt, there was a lot of blood and they didn't enjoy it."

"But - but, when the right guy comes along, I want to give him my virginity. Let him know that he's the first and that I've saved it for him."

"Sweet idea, and very symbolic, but it'll mean your first time won't be much fun for you. Better to let him break it with, I dunno, a vibrator, make you come another way, and then penetrate you when everything's healed and you're not sore."

"Yeah, I can see that might be a good idea. But what about my bum, Frank? That plug, it felt - it felt weird but so naughty and sexy. The vibrations went inside - I could feel them in my pussy, before I even used the other vibrator on my clit. And that bit just inside - you know, just inside the ring? The buzz, right there, felt so naughty and erotic. It was nice when you teased that place with your fingers, but the plug was even better. It was a bit difficult to get it in, because it was so big, but afterwards - WOW! It might be tricky to get your cock in there, but I bet it'd feel good."

My cock gave a little answering pulse at the suggestion of anal sex with this sweet girl.

Then she sat up, smiling broadly. "Hey, Frank, here's a naughty idea. Why don't we go out somewhere - I don't know, a pub or restaurant - with the plug in? And then I can, like, switch the vibrations on, and when I'm fizzing, you can slip your hand into my panties, or - or maybe I wouldn't be wearing any - and tease my clit so I come. Fuck, Frank, that'd be so naughty and so wild!"

"Very 'When Harry Met Sally', except you wouldn't be faking it. The problem is, you're very loud when you come. You'd be screaming the place down and everyone would be looking around at this dirty old man and his cute, innocent granddaughter." I kissed her.

"Frank, I'm not your granddaughter, and I'm not cute and innocent!"

"You're undoubtedly cute, but I'll admit that a girl who can deep-throat like that and is talking about anal sex isn't exactly innocent. I'm sure that the idea of clandestine sexual activity in a public place has a certain frisson to it, but do be aware that, with our age difference, I could easily end up getting arrested and having my career brought to a premature end."

"I - I could try to be very quiet. Keep my mouth shut."

"Nina, you're so vocal that I'd have to use duct tape, and that would be a bit obvious in public. Don't think I'm complaining. I love it when you moan and scream when you're coming. Just not in public."

"I don't scream!" she protested.

"You do. Next time I go down on you, I'll set my phone to record the noises you make before I start. You'll see."

She giggled. It was a lovely sound.

Then she lay down beside me again and snuggled in close. We kissed.

"Frank, you're amazing. You've been so kind to me. I don't know how I can ever make it up to you."

"Well, I think you've more than done that by sharing my bed and treating me to the best blowjobs I've ever had."

"But that's just the start, Frank. Like I said, I've done that for guys who meant nothing to me. But - but I'd like to offer you my arse as well."

"Charming!" I said, laughing.

"I mean, I'd like it if you'd fuck my bum. I want to experience that. I - I watched some anal porn on my phone when I was at Mum's and I couldn't sleep. The girl had an orgasm. It was so strong that she squirted pussy juices everywhere. I - I'd like to experience something like that."

"I can't guarantee I'll be able to achieve that - neither of us is a pornstar, so we haven't trained our bodies to make that sort of thing happen - but if you genuinely want me to try, I'd be delighted and honoured. God, just the thought of it has made me hard again!"

"Oh, I've got something that can remedy that!" she replied. And ten seconds later, her hot, wet mouth was descending on my stiff cock. And she didn't stop. Once again, I felt the tight grip of her throat as the head popped through, and she worked me up and down, in and out. She slid back, allowing me to slip out, taking a deep breath, and then plunging me deep, faster than before. Some frantic nodding of her head as she worked the most sensitive part of my penis through the tight hole in the back of her mouth was too much for me. I lasted all of a minute before she got a creamy meal.

We both slept well after that.

Over breakfast, she asked the question I'd been anticipating.

"Frank, when can we try it?"

"It?"

"Anal sex. I want to feel you inside me. It would be the best feeling, I'm sure."

"OK, Nina, sweetie. Let's take it one step at a time. Firstly, you need to work on the preparation. Anything bigger than that plug is going to go deep, so you need to be clean and then we need to test with the vibrator to see if it's going to work. It would be very frustrating and unpleasant for us both if I got half my cock up there and you started screaming in pain. So maybe later today we might..."

"Frank, I've already tried the anal douche. I did it again when I was in the bathroom, just now. It's not that bad. I thought it'd be revolting but it felt strangely - well, erotic, I suppose. Maybe it's the anticipation of doing something taboo, or the feeling of something inside my arse, even if it's only warm water. So, if you like, we could try with the vibrator, like - now? I want to see if I can have another anal orgasm. Would you like to help?"

Is the Pope part of a tradition going back 2,000 years?

We headed back to the bedroom, quickly undressed and Nina lay face-down on the bed. I retrieved the lube and both vibrators - a tapered one and the cock-shaped one we'd used the night before. Nina pulled her nicely rounded buttocks apart and I worked first one and then two fingers in and dribbled even more of the cold liquid into the enlarged hole, making Nina gasp. We pressed on, with me inserting a third digit.

"How's that?" I asked, slightly concerned by some of the noises she was making.

"It's - it's a bit - uncomfortable. Just - just hold it there while I get used to it."

"OK. Don't forget to push out. That opens the sphincter and makes it easier to - oh, yes."

She must've just done what I suggested because my fingers slid a centimetre or so deeper into her arse.

"OK, Frank. Let's just - just hold it there - for a - for a moment."

She seemed to be straining.

"Am I hurting you, sweetie? I'll stop if you..."

"No, Frank, please don't stop. We've - we've got this far and - and I don't want to go - go back. Not yet." She started taking deep breaths.

And then I realised that I'd forgotten something important. I snaked my free hand around the front and slipped a finger into her slit. She gasped, then lifted her hips a little to allow me to probe deeper. As I gently rubbed back and forth, taking advantage of the copious natural lubricant that was already there, her breathing changed and her little gasps were more of pleasure than of pain. Slowly, ever so slowly, I began to pull my fingers marginally back, then slide them in a little deeper, trying to bend them to stroke the inside of her ring.

"Try - try the vibrator now - please, Frank. I - I think you've - you've stretched me enough."

I extracted my fingers, as slowly and gently as I could, and then tried to turn the tapered vibrator on and coat it with lubricant, all using just one hand. Finally, I had the buzzing toy sufficiently covered in the slick liquid and positioned at the entrance to her anus. She let out a low moan.

"Oooh, that feels - that feels so naughty and sexy," she sighed.

I pushed, gently. Maybe a couple of centimetres of the toy's tip slid in before there was any real resistance. Then she let out a couple of short gasps, pulling her arse-cheeks wider apart as I exerted a little more pressure.

"Push out, baby. Let it in. Try to relax."

"It's - it's hard to - to relax when you're - OH! - getting your - arse fucked. But - OH! OH! - it - it feels - strange but - but sexy."

We'd chosen this vibrator because it was flexible, not hard, and had a gentle taper so that the stretch would be gradual. It also had a couple of raised rings around it. When I'd squeezed the second, larger ring inside Nina's arse, I pulled back slightly to see what would happen.

"OH! Oh, that's - that's - oh fuck, Frank, that feels perverted and - and - and WOW! Oh yes!"

It seemed the stimulation on the inside of Nina's sphincter was doing the business. I held the toy in place while the strong pressure from Nina's arse tried to push it back out, before pushing it a little deeper, then letting it drop back for further stimulation of her sphincter. Then a little deeper still, then back. And then further.

When we reached the thickest part of the vibrator, which I judged to be about the same thickness as my cock, Nina was moaning rather incoherently.

"Oh fuck - so - so - oh yes - so deep - fuck that's - that's right up - right up - OH! Oh God! OH! Oh, Frank, it's - shit it's right in - it's OH! OH! Fuck! I think - I think I'm going to - going to - OH YES! YES! YES!"

Her hands released her buttocks and gripped the sheet as she continued to make a series of random noises and her legs started to shake. I worked the vibrator in and out, pushing the thickest part through the tight hole and pulling it back, as the middle finger of my other hand rubbed her clit - and kept rubbing as she moaned and writhed.

"STOP! Please stop! I can't - can't take any more. Please - please pull it out. Gently..."

I did as she asked, easing the toy out, making her yelp again as the thickest part expanded her sphincter one last time, and then the ridges stimulated the inner surface before pulling free. I left my finger in her slit, but let it lie still inside that wet valley.

"How was that?" I asked.

"Of fuck, Frank, you saw - and heard - how it was. Oh my God, it was so strong!"

"It sounds like you're ready to try the next stage," I said, not entirely sure what that stage might be.

"Not - not yet, Frank. I think I might be - a bit sore. I need to - to recover. Hold me, Frank. Please."

I wrapped my arms around her and she snuggled up close.

"It's OK, baby. There's no rush. This is about you getting pleasure from new experiences. Do you feel you're getting there?"

"Wow! I mean, wow, Frank. I'm a virgin; well, sort of, though I'm not sure whether you can still call my arse 'virgin' after what you just did. But - but now I get why a girl might want to be penetrated. And, Frank - I want it to be you. I want to feel you inside me. You, Frank. I'm - I'm still not sure that my pussy's ready but - well, soon, Frank, I want your cock up my arse. I feel so naughty and excited just saying it, but I'm sure it's going to feel special, and I want it to be special for you, too."

"Nina, sweetie, everything we do together is special. I'd be honoured and delighted to do what you ask, whenever you feel you're ready, but don't feel you have to rush into anything."

"Thanks, Frank. You make me feel so safe, in a way I haven't felt at home since my Dad was alive. But I've noticed you have a boner again. I don't think my arse will take anything else in it tonight, and my throat is a bit sore, but - well, how about a tit-wank? We have lots of nice lube!"

Celia wasn't well enough endowed for the task that Nina carried out, so it was something of a novelty. Sure, it wasn't as much fun as an actual fuck - vaginal or anal - or as intense as being deep-throated, but looking down at the expression of deep concentration on Nina's sweet face as I straddled her body and she pressed her breasts tightly around my cock, and being enveloped in that silky, well-lubricated valley, was enough for me. It only took a couple of minutes. As I wasn't holding on for her pleasure, I just let myself come as soon as I was ready - before Nina got a very messy facial, which she seemed keen to gather up with her fingers and devour.

"Your cum tastes nice, Frank. Better than - better than Gerry's."

I was shocked. "Has he really forced you to suck his cock?"

"Oh yes, as well as groping me. He wanted to fuck me too, but I wouldn't let him. He's started threatening to fuck Gemma if I don't let him fuck me, and that's - that's scary."

"Shit, Nina - I never realised how serious this was. I don't suppose you have any proof? You know, audio recordings on your phone?"

"No. But - but I could see if I could get one."

"That's dangerous. If you let him start, he might press on and rape you."

"I know. But - but that's given me an idea." Nina had an inscrutable smile but would say no more.

We spent the rest of the day just chilling out. Nina was on her phone quite a lot, seemingly messaging Gemma. Later, I drove us down to the river and we walked along the Embankment. Although it was December, it was sunny and not too cold. Again, Nina linked arms with me as we walked, occasionally leaning in when we stopped to rest her head on my shoulder. I put my arm around her and she smiled up at me.

"Frank - thank you."

"For what?"

"Everything." She reached up and kissed me. "Just everything."

Later, I cooked us a light supper and we watched a couple of things on television before going to bed around nine, in anticipation of further sexual activity. I wasn't disappointed.

"Frank," she said shyly as we lay together, naked under the duvet. "Would you - would you tie me up, please?"

"Why would I do that?" I asked, surprised.

"I just - I've just got this urge to feel like I'm helpless and being forced to come. You will make me come, won't you? And then - then you can, like, use my mouth..."

I was careful not to tie the old neckties too tight around her wrists and ankles. I had to link some of them together so that she was spreadeagled in the middle of the bed, with pillows under the middle of her back and her rather nice bottom. She wanted me to blindfold her too, so I used an old sleep mask I'd got from a plane journey some years earlier.

And then I went to work. I used an old shaving brush to tease her skin, interspersing it with licking and teasing with my fingers. I nibbled at her neck and throat, I tantalised her inner thighs, I licked her armpits and behind her knees.

Then I started teasing around her outer pussy lips with my fingers, occasionally darting in to lick or suck her nipples. After around thirty minutes she was begging for release.

"Oh Frank, make me come! Make me come! Please!"

"No. Not yet," I replied with a smug smile she couldn't see. Ten minutes later and she was writhing around, trying to get my naughty fingers to stop skirting the most sensitive parts of her pussy and get into that flooded valley and onto her clit. Finally, as she was moaning deliriously and begging me to finish what I'd started, I went in with my mouth. After less than a minute, during which she moaned and screamed almost hysterically, she started bucking off the bed as far as her restraints would allow. I had to hold her down as I mercilessly devoured her clit, and she jiggled like a crazed marionette in her bonds.

When I finally relented and stopped torturing her pussy, she lay panting for quite a while. Then she murmured, "You can fuck my mouth now."

"It's OK, sweetie, I'll just..."

"Do it, please, Frank. Use my mouth. Stick it in my throat."

It sounded so brutal I objected. "Nina, baby, I can't..."

"Please, Frank. Please feed me your cock. My throat can take it. Give it to me. I can't resist, tied up like this. And I don't want to. Use me."

I couldn't. I really couldn't. Nina was a vulnerable kid. She was over-sexualised. I was in loco parentis, looking after her. I...

Then she opened her mouth wide and made little hawking noises in her throat. "Do it!" she croaked. "Please stick your cock in my mouth. I won't shut up until you do." It seemed she was asking to be dominated, something I don't usually feel comfortable with, but...

I moved around and tentatively pushed the head of my cock between her lips. She lifted her head to take more of me. And yes, I pushed deeper. I couldn't help myself. Before long, I was straddling her body, lifting her head so that my prolonged invasion of her mouth, and then her throat, was possible, given the angle. She pushed her head forward to meet my thrusts, making those erotic and somewhat scary gagging noises, until I inevitably reached my own orgasm. She gasped and gurgled at the flood of semen I deposited into her throat. When I withdrew, my cock still tingling, she said, rather hoarsely "Thank you, Frank."

"What?" I slumped back onto the bed beside her, finding it hard to believe what I'd just done. This was depraved and a complete abdication of my responsibility toward this poor kid, who...

"That was fucking amazing. I could feel you pulsing in my throat. I love that feeling."

"What? How? I mean..."

"Look, Frank, sometimes it's fun just to be helpless and have stuff done to you. I just wanted to be used - and to come, of course - because..." She paused as if examining her motives. "Because I want to surrender myself to someone I care about, who'll only use me in ways I want to be used. If I'd asked Damien to tie me up, he'd have taken my virginity, probably hurt me, come inside me and then told all his friends. But you, Frank, you did exactly what I wanted; to be helpless, teased and forced to come, but only when I was begging for it. And I craved that feeling of power, to open my throat and actually feel you throbbing as you came, knowing that I'd done that. I so needed to just give up control and let someone I cared for do things to me that were naughty and dirty and so sexy. I wanted to lose all control. Oh, I don't know Frank. I just can't do the psychoanalysis. Just untie me now, please, and then hold me."

Afterwards, I rubbed her wrists and ankles to restore circulation as we listened to the recording I'd made of our latest little sexual experience.

"Fuck, Frank! I do scream, don't I? I never realised. But - but it sounds sexy, doesn't it?"

"Very sexy. Dick-stiffeningly sexy, but I can't take any more tonight and, I suspect, neither can you. Come here." I wrapped my arms around her and we kissed.

As Nina slept in my arms, I pondered again on what was going on. Was I exploiting a damaged kid? Was she using me to get thrills she didn't dare seek elsewhere, just because she trusted me? Should I end it, before it got out of hand and maybe threatened my career and reputation? If I did, how would Nina take it? How would I take it - losing someone I genuinely cared about? I finally dozed off with all the weird contradictions buzzing in my brain, and a warm glow emanating from my well-sucked cock.

After breakfast, we both showered and dressed, and then we went out to a nearby shopping centre. It remained mild for December, and Nina looked rather sweet in a short, black dress, a leather jacket and knee-high boots - similar to her usual goth attire, and with the long, half-green hair and her facial piercings again defiantly in evidence - while I wore my usual jeans and sweater. The streets were busy with the sales, every hint of Christmas now gone.

As we passed a branch of Ann Summers, Nina suggested that we go in. I'd only ventured into one many years earlier, looking for ways to spice up the sex I'd enjoyed with Celia.

"I'm not sure. I don't think we should do this together. Look," I said, getting my wallet out. "If you want to buy something, here's twenty quid. Thinking about it, you might need more," I said, handing her another twenty. "But we shouldn't be seen together in somewhere like that."

"Why not? I can fuck whoever I choose," she said defiantly.

"Keep your voice down! Yes, you can, but in private. If someone in there notices the two of us looking at sex toys, they might suspect grooming and report it. That would cause a lot of trouble, especially for me. It's probably best if I don't come in with you."

I found a bench and sat, checking my phone, while Nina browsed. She came out carrying a bag and with a smug expression on her face, but didn't say anything - and I didn't ask. I thought that she might want to surprise me, and the thought of that instigated a pleasant swelling in my underpants, as well as a worrying feeling of conflicted interests in my addled brain.

We went into Pret, and she headed to the ladies' while I bought us each a sandwich and a coffee. While I was waiting for her to return, my phone rang.

"Hello, is that Frank Parker?"

"Yes. Who's calling?"

"I'm DS Hobbs. Chief Inspector Wallace asked me to call you if we found anything on a Gerald Pascoe. It's somewhat irregular, sharing police records with a civilian, but Mr Wallace said you needed to know. Well, there's not a lot, but what there is looks - er - interesting. Pascoe was cautioned eight years ago after a fifteen-year-old girl complained that he'd groped her at a party. His wife put a restraining order on him, and..."

"Sorry - you say 'his wife'? I wasn't aware he was married back then."

"Yes, his wife is - or was - an Amanda Pascoe. An address in Beckton. She complained that he was violent and had sexually assaulted her twelve-year-old daughter. The child was from an earlier marriage; the Pascoes had only been married about a year when this happened."

"Was there any investigation of the sexual assault?"

"The girl was questioned but was reluctant to talk about what happened. It seems the mother just wanted him out of the house and wasn't willing to press charges. The notes indicate that they both looked frightened and the mother seemed angry, but the officer investigating felt they simply wanted shot of him. Uniform were later called to a disturbance when he was banging on their door, in defiance of the restraining order, clearly drunk, but he left when the officers arrived and, again, the wife didn't want to take it any further. There's also mention of another alleged sexual assault on a girl of fourteen, two years later, but again, no witnesses and the case was dropped."

'And so it goes,' I thought. 'He moves on to the next victim because the last one just wants a quiet life, unpolluted by Gerry Pascoe.'

"Thanks, Sergeant Hobbs. I'll speak with Chief Inspector Wallace and see if he feels there are grounds to investigate Mr Pascoe's current activities further. Could you please check whether he actually divorced the first wife and get back to me?"

"MARRIED!" Nina exclaimed when she returned and I told her about the conversation. "Mum has no idea he was married before she met him! He might still be, which would make him a fucking bigamist! And he's tried it on with other young girls! Fuck!"

"Keep your voice down, Nina. But yes, it seems a pattern is emerging. Have you spoken with Gemma?"

"I called her while I was in the loo. She seems OK and says Gerry is being quiet - probably hung over - at the moment. When we were messaging yesterday, we agreed that if he tries to come into her room, she'll call me on speed dial and then leave the phone face-down by the bedside. If I see it's from her, I'll pick up, go on mute, and record the call. If she shouts for help, we can come off mute and warn him he's been recorded and the cops will be on their way. Does that sound like a plan?"

"A very good plan. Nina, you're a cunning little vixen. It's probably the best way to protect your sister while you're with me, and any recording might finally convince your mother she needs to listen to her daughters. Hopefully, it'll also get Gerry behind bars where he belongs."

"Yeah, that would be a result, though I don't want Gemma to have to go through that. But Frank?" Her face took on what I would call a 'conspiratorial' smile.

"Yes?"

"Remember what I said? About being in a public place..."

"You haven't!"

"I have, Frank. I bought a new plug in Ann Summers. It's in place - I brought the lube with me - and switched on. And - and here are my panties." She reached across the table and handed me the small, crumpled garment. I rapidly put it in my pocket.

"Frank, my pussy is so wet that I'm going to leave a damp patch on the back of my skirt. It feels so deliciously naughty. I mean, I'm totally exposed if someone looks up my skirt." She shuffled along the bench opposite me where she was sitting, past the end of the table, and gestured for me to look down. Then she pulled the front of her short skirt up to her waist and opened her legs. The delicious pink slit was clearly wet, and I could just make out the end of an anal plug at the back. She smiled, pulled her skirt down and slid back to her earlier place.

"Do you like it?" she asked with a slightly nervous smile. "I mean, I'm not - not going too far, am I?"

I laughed. "Nina, you're a constant source of surprises. You'll only be going too far if we end up attracting the attention of someone who thinks I might be a pervert, grooming a young girl."

"Maybe - maybe you are a pervert after all, Frank. I mean, I bet you want to fuck my bum right now, don't you?"

"No," I said, lying.

"Ha! Yes, you do, Frank. It's written all over your face. And you know what? I want you to. Can we go home now, please?"

"You - you want me - you want..."

"Absolutely, Frank. It was so good yesterday, but it was intense and I thought I'd be sore today. But I'm not. The plug I bought in the shop - it's bigger than the one we used the first time. I - I sort of knew, when I got up this morning that today would be the day, so I douched after breakfast and - I lubed and put in the small plug. And then, when I saw the bigger one in the shop, I wanted to try it. Frank, it feels amazing. I have to keep trying to distract myself so I don't come yet. But please, can we go back to the car? And then, would you please rub my clit for me? I so need to come, very soon, and if we don't go somewhere private, I'm gonna come right here. And then..." She leaned close. "And then I need you to take me home and fuck my tight little arse. Will you do that for me, please Frank?"

How I made it back to the car, I have no idea. I managed to adjust my erection inside my pants before we left our table at Pret, but the memory of what Nina had said, the fact that I knew she was pantie-less and anal-plugged under her short skirt, and the way she kept slipping me sly smiles as we walked, were all excruciating.

Finally, I unlocked the car and we both climbed in on our respective sides. She hitched her skirt up and gasped "Now, Frank! Please - I need to come right now!"

I reached across past the gear lever and slid my hand between her legs. She wasn't exaggerating - she was quite literally dripping. It took maybe a minute before she clamped both hands over her mouth to muffle the loud cries that emanated from her mouth. I glanced around, but there wasn't anyone nearby in the car park. Which was just as well, because despite her efforts to reduce the volume, she was still loud. And I held on as her legs shook and she writhed around in her seat. I idly wondered whether pussy juices would stain the leather.

"Take me home, Frank," she sighed. "I'm ready."

I didn't ask what she was ready for, but I got us home in record time.

She got out of the car rather unsteadily and, once I'd opened the door, headed straight up to the bedroom. As I hurried behind her, I could see up her short skirt and admire her shiny, wet pussy and the rather large plug in her bum. I followed in anticipation.

In the bedroom, she shed her jacket, pulled the dress off over her head, unzipped the sexy knee boots and climbed onto the bed, manoeuvring two pillows underneath her.

"Frank, do it soon. When you're ready, pull the plug out and go in. I - I'm fizzing like crazy, and now - now's the time. I so want to feel you inside me before I come again."

I could've asked if she was sure. I could've suggested that she might not be ready. I could've taken her in my arms and just held her.

But I didn't. I almost tore off my clothes, retrieved condoms and lube from the bedside, and climbed onto the bed behind her. My cock was hard and throbbing as I rolled on the rubber - a recommended precaution to prevent infections - and slathered lubricant over it, then reached for the buzzing anal plug.

"Pull - pull it out slowly," she murmured, her head down on the mattress, her bum raised, her legs spread. "Ooh! Oh, that's - that's so weird. It - kinda hurts a little but - but it's almost - almost making me come!"

The plug - significantly bigger than the one she and I had bought online, finally popped out, still buzzing. I held it in place, the tip protruding just slightly into the vacated hole, as I squirted more lube over it, then slid it a little deeper, making sure there was plenty of gel to ease my entrance.

"Oh, quick, please Frank. I'm going to come - very soon and - and I - I want you inside me - when - when I do. Oh!"

"Push out, baby," I said softly as I tossed the plug to one side, shuffled between her spread legs and positioned the head of my rubbered cock against the hole. She gasped as I pushed, holding the shaft of my cock to prevent it from sliding sideways which, given the amount of lube and the small hole it was trying to enter, was a real risk.

Nina gave out a series of little gasps. My cock advanced so slowly, millimetre by millimetre, and Nina's cries became more urgent.

"Baby, I can stop if you..."

"NO! Keep going. Just slowly. It feels so big but - but I want it, Frank. I really, really want - want to feel your cock - in my arse. I know it's - going to be uncomfortable for a bit - but it doesn't really hurt. Just - just keep going until - until I say stop."

Glancing down, I could see that she'd moved one hand between her legs and was rubbing her clit. I had one hand guiding my cock and the other gripping her hipbone. The pressure on my cock-head was almost excruciating; she was so tight. I felt I shouldn't be doing this. I'd imagined something romantic, gentle, lots of foreplay. Not this - sudden, unexpected, direct. And...

And then suddenly, the head of my cock popped through her tight ring and slid forward a couple of centimetres. I gasped and Nina gave a little grunt. I moved my hand, now no longer needed to steer, onto her other hip to brace myself and started to slide deeper.

"Stop! Woah, Frank. Pull back a little. Not too much. That's - OOOH! YES! Oh, I love that! I wanted to feel it, pulling on the inside of my arsehole. You - oh yes, Frank - you're doing it right. You can go deeper, but keep pulling back just - OH YES! YES! Just like that!"

A moment ago, I'd felt trepidation that this was all going to be a fiasco - pain for Nina and frustration for me, having to stop and withdraw. Now - now we were opening a new chapter in our relationship. I was inside her - inside her sweet, sexy little body. Not, perhaps, as nature intended, but very much as Nina wanted.

Tentatively, I eased forward. She let out a low moan.

"Oh, that's - that's - so weird. But - but good. Pull back again, please and - OH! OH YES! You - you've got the action, Frank. Just - just do it, now. Just - just fuck my arse. Please?"

The next few minutes were a mix of intense concentration and sexual bliss. Sure, I loved Nina's blowjobs, loved exploring her sweet young body and her silky skin and licking her even silkier pussy. But this? I was inside her. I was fucking her - or, more accurately, sodomising her, doing something I'd never done with any woman - and she seemed to be enjoying it as much as I was. Except that there was this constant fear that I might hurt her, or reach a point where it was no longer giving her pleasure. As I slowly, tentatively edged ever deeper inside that oh-so-tight hole, I was worried that, at any moment, she'd scream with pain because of my clumsiness and it would all be over. But every time I slid back and tugged on the inside of that ring, she made more approving noises. And she seemed to like it when I pushed in, a little deeper each time. Could it be...?

And then my abdomen touched her sweet, smooth, rounded buttocks.

"Oh fuck, Frank! You're all the way in!" She giggled. "I'm a big girl now! I've been fucked right up the arse!"

I took my hands off her hips, moved one to a breast and the other to her pussy - nudging her own hand out of the way - and bent to kiss the back of her neck.

"OH! Oh, your cock twitched inside me. It - it felt..."

"Weird?" I ventured.

"Frank, it all feels weird. And naughty, and dirty, and sexy and - and exciting. I've never done this - anything like this - before."

"Neither have I."

"How - how does it feel to you, Frank?"

"Amazing. Very sexy. I feel - I feel so close to you, Nina." I wanted to say something else but shied away from it.

"Frank, you can't get much closer than - than right up my arse!" She giggled again - and then gasped as I simultaneously rubbed her clit, pinched her nipple, and slid fairly abruptly back about ten centimetres and pulled on the inside of her ring.

"Oh fuck, Frank! That's - that's awesome. Make me come, Frank, please! Then - come in my arse. That would be - perfect."

Coordination is a knack. Stroking a clit, squeezing a nipple and fucking a tight little arse at the same time is tricky, and perhaps the concentration needed was what stopped me coming too quickly. Celia's pussy - and that of the escort I'd used, and of the one or two girls I'd had before I met my wife - none had been as tight as Nina's hot young rectum. And, perhaps because I'm not exactly generously hung, I'd never had such an enthusiastic response from any of those women as I was now getting from Nina. I loved the way she gasped and moaned every time I pulled back against that ring - and every time I thrust in as deep as I could go - as well as her response to my stimulation of her clit and nipple.

Finally, she gasped "Don't stop! Please, please keep fucking my arse! Keep rubbing my clit. I'm going to come! Oh God, I'm going to come!"

It wasn't the first time I'd confirmed a woman's orgasm by feeling the contractions in her arse. With both Nina and Celia, a finger up the bum at the crucial moment had been an undeniable orgasm indicator. But this was the first time I'd felt that through my cock, and the experience was breathtaking. And cum-taking, as Nina's tight little rectal tube milked the semen out of me. Honestly, I'd never experienced anal sex before and hadn't had vaginal sex in ages, so it was hardly surprising that when Nina went into orgasmic overdrive, she dragged me with her.

I collapsed forward onto her, and she yelped, so I quickly released her breast and pussy and lifted myself off her again, with the throb of a powerful orgasm radiating out into my body from my tightly-imprisoned cock.

"FRIG MY CLIT! FRIG MY CLIT!" she squealed, so I rapidly returned my hand to her pussy and resumed rubbing. And despite my orgasm, I had enough of an erection to manage a few more thrusts and pulls, to prolong her climax as long as possible. Until she let out a long groan.

"Stop! Please! Can't - can't take any more. Please!"

I let out a long sigh and carefully lowered myself onto her, holding my weight this time as I again kissed the back of her neck.

"How was that for you, baby?" I asked.

"Awesome! Fucking - fucking awesome! Shit, I've never, ever, come like that! So - so strong!"

She turned her head and we kissed. "How was it for you, Frank?"

"Unbelievable! Yes, that was about the strongest I've come in a long time."

"Even stronger than down my throat?"

"Even than that. You, Nina, are a sweet little orgasm machine - at least for me."

She kissed me again. "Except I'm not sweet."

I laughed and kissed her back.

"No, I'm really not." She turned slightly and my softening cock slipped out. Then she rolled over and I slumped down beside her, somewhat out of breath. "Look, at me. I'm a Goth. I gave you deep throat and a tit-wank, and then I let you fuck my arse..."

"Let me? You practically begged me..."

"And that's my point, Frank. I'm not sweet. I'm nasty. I'm - I'm..."

"Gorgeous? Delightful? A bit vulnerable? A bit spiky? But strong, determined, protective of people you love, friendly and very accommodating towards sad old men..."

"Shut the fuck up, Frank, and just hold me, will you?"

I did. And I don't think I've ever felt happier - certainly not since Celia died.

I noticed after about ten minutes that she'd dozed off, obviously feeling safe and comfortable in my arms. And that gave me conflicted feelings. On the one hand, Nina trusted me and wanted to be close to me. On the other, she was a vulnerable kid to whom I should never, ever, be doing the things I'd done.

But - but Nina was more than any kid I'd ever comforted before. Much more. There were three words I wanted to say to her. Three words I knew I daren't say.
