England, present day.

David looked at the old battered cardboard shoebox and ran his finger along the elastic band that kept the lid firmly in place. The word PRIVATE was staring at him, and he knew that he shouldn’t even consider opening it. His sweet wife, Melissa, was at work and not due home for another few hours at least. Enough time to see what was inside, and reset everything to where he had found it deep with Melissa’s wardrobe tucked away behind a pile of old clothes that she didn’t wear anymore that had fallen to the floor awaiting a tidy up, or clearing out. Opening the box, he found an envelope inside with his name on it, but to his frustration it was sealed at the back. Had Melissa wanted him to find it? If he dared to open it, she’d know he’d read what was inside. Maybe she’d forgotten it was there, or was waiting for the right moment to give it to him. The temptation was too much, and David carefully opened it, but unable to avoid tearing the envelope. Shit, Melissa will know for sure now, might as well read it. He took out the letter inside, his hands trembling with the illicit excitement, and his cock already getting hard in anticipation.

****

To my darling husband David,

I am writing this to apologise for my behaviour the other night, when you showed me those huge knotted sex toys online and asked me what I thought of them. I flew into a rage and called you a pervert. You see, it took me by surprise and I had no idea such things existed. Darling, seeing those things awakened something in me from long ago that I have shut out for years, and given that you wanted me to see those wild dildos, I’m hoping that you enjoy what I’m going to tell you, or it may shock you. Either way, I feel I must tell you.

You’ve always been interested in my sexual past before we met, and from time to time you’ve asked me what my best sexual experience was before we got together. I’ve told you a couple of naughty stories about me with other guys from my single days, that you enjoyed and we’ve had great fun around it, but darling, I’ve been too embarrassed to tell you about the far and away best sexual experience I’ve ever had, for obvious reasons as you will see. I’ve always loved your open-minded attitude to sex, but I think what I’m about to confess will test that.

I remember all the details as if it were yesterday, so here goes. I love you, Melissa xxx

It was towards the end of my 1st year at university, so 1992, and I’d be 18, way before we met. I was in my university town (you know the one) having a night out with my best friend at the time, Sinèad. You’ve commented from the old photos I’ve shown you, that you think Sinèad and I were a couple of hot looking girls back then. Although Sinèad was in the same year as me, she was a year older and way more sexually experienced and confident.

It was just the two of us in the Student’s Union bar one night, gradually getting drunk and naturally the conversation turned to boys, having a laugh about some of the guys we’d gotten off with, how far we went with them and so on. Sinèad asked me who’d given me the best shag so far, and I blushed saying I’d not actually had that many.

“You’re only young once, Melissa. You should fuck a lot more,” she teased me. She pushed me for the guy’s name, so I told her, and what we did together. I then waited for Sinèad’s best story, but she went all shy, so I kept at her, getting more and more pissed off when she wouldn’t tell me.

“It’s not a guy,” she said eventually, then went quiet and looked embarrassed, which really wasn’t like her.

“Oh, that’s okay if it’s a girl,” I said, even more curious as to who it was and if I knew her. I didn’t know that Sinèad was into girls.

She still wouldn’t tell me and I got even more annoyed that I’d told her my one but she refused to tell me hers. I went to the bar and got us a couple of shots and when I got back I said, “Look, this isn’t fair. I’ve told you mine and you won’t tell me yours. Come on, I want to hear it. Spill the beans or I’m leaving.” I was really pissed off!

“Can you keep a secret?” She looked really sheepish.

“Of course,” I said, wondering if she was shagging a lecturer or something. “You’re my best mate.”

Sinèad downed her shot and smiled nervously. “Zak”.

I laughed as I knew she was joking of course. Zak was her family’s pet dog, a fully grown male German Shepherd. Her face went bright red and I realised with horror she might be telling the truth.

I just sat looking at her with my hands over my mouth. I was speechless, totally shocked, but in all honesty I also felt weird butterflies in my stomach that I couldn’t control even though I knew what I’d heard was so wrong. My disgust was unexpectedly mixed with odd primeval feelings that I tried to fight.

My inquisitiveness got the better of me, and I asked question after question, I couldn’t help but to want to know more. Sinèad told me it had “just happened” a few weeks previously when she was at her parents home for the weekend and her mum and dad were staying over at friends. It started with Zak sniffing her crotch as he was in the habit of doing, but for some reason this time she didn’t stop him as she normally would. It flicked a switch in her and one thing led to another, as they say. She said that in no way did she force him and that Zak definitely wanted to sniff, then lick her pussy, then she ultimately ended up letting him take her from behind. She said it was a really weird looking cock, and way bigger than any guy’s she’s had, but that seeing it so naked and aroused turned her on so much, she didn’t stop whatever he wanted to do with her.

“He’s always been a randy dog, keeps trying to hump my leg – and my mum’s. I don’t know why I didn’t stop him this time. It just felt really wild and that turned me on. I think he’s been trying his luck for years with me, I finally gave in,” she laughed.

At this point a couple of good-looking sporty lads we knew from the University rugby club asked to join us. Ordinarily we’d have said yes but I instantly declined, telling them we just want to be the two of us. I was craving the details of my mate’s sordid behaviour. I remember her telling me the orgasms from being pounded from the rear by a big strong dog are way more intense than from any guy, even though she didn’t experience the knot, which she said she was really disappointed about. She had to explain what the knot was, but I still didn’t really understand.

We sat quietly for a few minutes, and I have to admit I was wrestling with all sorts of emotions at what I’d just heard from my best friend.

Eventually I said, “You know you could have any guy in here, don’t you?”

“So could you, Melissa,” she nodded towards the guys who had asked to join us. “All the Uni rugby team lusts after you, but I bet none of them could do you like my Zak could.”

“Sinèad!” I protested.

“You’d love it, you dirty bitch,” she giggled. “You should try it. Zak’s not going to tell anybody is he, not like the pricks in Uni and their guy-talk.”

Of course I told her no way, but later when I got back to my dorm room my knickers were soaking through from thinking about Sinèad being fucked hard from behind by that big dog and I played with my fanny for hours feeling really guilty of the forbiddenness of it all, but also being off the scale horny too. One of the guys I’d slept with had shagged me from behind, and I really liked it. It made me wonder what Zak had done to Sinèad. I barely slept that night, just constantly practicing being in the doggy-style position sticking my bum into the air in anticipation of an imaginary horny big beast, whilst sticking my hairbrush handle up me and rubbing my clit thinking what it would feel like. The shame of being turned on and masturbating to the thought of being fucked by a horny powerful dog only made my orgasms more intense.

We didn’t talk about it again for a few days, and I could tell Sinèad was avoiding me, obviously ashamed about opening up to me with something so private, and taboo.

However, the next time we had a drink together, I just had to tell her that I’d been masturbating so much about what she had told me, even though I felt really guilty about . Sinèad smiled and said she’d hoped I’d bring it up again and we excitedly talked about her experience again.

Then she sprung a surprise on me. Sinèad suggested I could to stay the night at her mum and dad’s over the holidays when the rest of the family would all be away to Spain. We’d have the house to ourselves, so she said we could get drunk and see if Zak would treat us girlies to a good time, but it’d be up to him.

“If he’s not interested in us, we could just get pissed on my dad’s expensive booze, smoke and listen to music,” she said.

“I don’t know, Sinèad. I don’t think I’d want to, you know, with your Zak,” I replied hastily. I was excited by the thought, but tried to suppress it, disgusted with myself for even contemplating it.

“You don’t have to do anything, honestly.” She reached to hold my hand with both of hers. “Just come over and we’ll have a laugh.”

“Well, okay then,” I smiled.

“But I’ll tell you what you need to bring. Just in case you do fancy a bit of naughty fun with old Zakko,” she smiled, causing a little tingle between my legs.

I didn’t really think I’d go through with it, and tried to suppress any excitement that crept in as the days went by and the end of term approached. However, no matter how hard I tried, I thought of nothing else in the lead up to that night and despite some last minute nerves I decided to just go to Sinèad’s for night of drinking and music if nothing else. So there I was on the train at 6pm one Friday on a warm June day, my Walkman with a KLF tape loaded helped to take my mind off why I was really travelling through to spend the night at Sinèad’s mum and dad’s. I clutched my plastic Blockbuster carrier bag which contained a fresh top for the next day, three pairs of clean cotton knickers as a girl can’t be too careful, my toothbrush, a bottle of vodka, and two packs of cigarettes. Oh, and the items that Sinèad had briefed me to bring…

I walked up Sinèad’s parents’ driveway and stood at the door. No turning back now. I rang the doorbell and my stomach churned when I heard Zak’s scary bark, much more intimidating than any other dog I’d heard. What am I doing, I’m an attractive and intelligent 18 year old girl, that guys fancy and I have no problem pulling whenever I want to. Am I really going to have sex with my best mate’s pet dog? I exchanged polite hellos with Sinèad’s middle-aged next door neighbour who was in his garden.

“Sinèad having a party whilst her mum and dad are away on holiday, eh?” he smiled and winked, letting his gaze linger on my hips and bottom a little too long for my liking. I was glad I chose to wear my comfy baggy jeans for the journey over, although I was wearing my favourite strappy wedged heel espadrille sandals from Next, that showed off my cute painted toes and pushed my bum cheeks up and out. I’m sure that all helped to encourage his perving.

“Nah, it’s just me,” I laughed nervously.

“You one of Sinèad’s pals from Uni?”

I nodded with a forced smile.

“In your first year like Sinèad?” He dropped his gaze down my entire figure, before having a good look at my feet in my wedges.

“Yeah,” I replied, feeling very self-conscious.

“Very nice,” he went on, winking at me again before letting his eyes settle on my breasts. I had a sensible top and bra on but still, I self-consciously adjusted my stance and wished I’d worn a jacket. “Bet you’re having lots of fun at University, if you know what I mean,” he smiled.

“Nah, not really. Too busy studying.” I rang the doorbell again, impatiently, which caused more loud barking from inside.

“I don’t believe that, a couple of good looking young girls like you and Sinèad. What’s your name then?” he was looking towards my hips again.

“Melissa,” I replied staring at the front door, willing it to open.

“Well, Melissa, I promised I’d keep an eye on the house for them, don’t be smashing the place up,” he winked at me one more time. I instantly felt he knew the sordid reason I was there, and I could feel my face go bright red.

Thankfully, I was saved by an excited Sinèad greeting me at the door. “Oh, hi Mr Jones,” she said whilst ushering me inside. “He’s a randy old pervert, he’s always saying suggestive things to me and my mum. I bet he’s touching his dirty old-man cock to you right now.”

“Yuk,” I responded. We were stood in the hallway inside the front door and I could hear Zak sniffing and scratching at the kitchen door, where Sinèad had closed him in. “Look, I’m really nervous about this whole thing.”

“Just have a drink and relax, nothing will happen if you don’t want it to. Anyway, Zak’s got good taste. He might not even fancy you, you ugly fucker,” she laughed, digging her fingers into my ribs. I hadn’t thought of that and felt instantly disappointed. That told me something.

“Did you bring a short skirt and old t-shirt or something?” asked Sinèad excitedly.

“Yup,” I said and pulled out the skirt. It was that lightweight miniskirt from Chelsea Girl that I still have and you love me in. She’d recommended to bring a short skirt along as it gave the dog ready access to smell your private parts but made it easier to just pull it down again should anything be happening and the doorbell goes or something. She said the t-shirt was because his front paws on your back could be a little rough if, you know, were to actually happen. I wasn’t sure I liked the sound of that. I also had to make sure not to put on any perfume or deodorant to let my natural scent come through. It was all very matter of fact preparation.

“Perfect,” smiled Sinèad, and led me through to the kitchen to meet her Zak. I have to admit, he was a lovely dog and very friendly, well groomed and well behaved, but oh my god he was huge and muscular looking, bigger than I thought he’d be. Butterflies fluttered in my stomach, what in god’s name am I doing? I’d be lying if I said I wasn’t excited though. I patted him, trying to avoid being whacked by his wagging tail.

Sinèad had already taken Zak for a long walk, cleaned him up and fed him, so he seemed content to just sit with us quietly chilling whilst we drank my vodka and chatted in the kitchen. I gave him a couple of claps and head rubs and he was a lovely natured big thing. As time went on, the conversation was all about uni courses, guys and the gossip about our mutual friends. I wasn’t sure if anything was going to happen and felt okay with it, but a little disappointed, which told me that deep-down I wanted the excitement of seeing what could happen. I think both of us were nervous to be the first one to mention the big reason why we were both there.

This went on for a couple more vodkas then Sinèad suddenly said, “So… Zak…”

I smiled and raised my eyebrows to encourage her to continue.

“Are you tipsy enough to see if he could be interested in us?” she smiled.

“I’m not sure.” Truth was, I was nervous but excited.

“Well, why don’t we change into our skirts and t-shirts, and just see what happens.”

“Okay,” I said, glad that Sinèad was confidently taking the lead. I went to the bathroom with my bag to get changed.

When I was in there, Sinèad knocked on the door. “Whilst you’re in there,” she said. “Have a pee, but let some drip into your knickers, he likes that.”

So I got changed into my little skirt and t-shirt and for some reason I took my bra off so my little tits were free underneath, it just made me feel sexier. All the guys liked my tits, and I have to admit, so did I, they were nice and firm with lovely small pink areolae, about a handful each. I also did the pee thing onto my knickers and and rubbed quite a lot over my fanny too for good measure. The preparation was arousing me. I was getting dressed for sex. I applied heavy eye make-up, my pale pink lipstick, a little blusher, and even brushed my hair into a sexy style that I usually kept for going out on the town. I was dressing up to pull. The vodka must have been kicking in, as I allowed myself to be turned me on thinking about the dirty reason I was doing all this, was to make me sexually attractive to Sinèad’s dog. I checked myself out in the long bathroom mirror, and noted with satisfaction my erect nipples poking up through my t-shirt, that little skirt barely covering my bottom, my smooth shapely legs that I’d freshly shaved and moisturised that morning together with my armpits, and my trashy rings on my fingers and dangly earrings. I wondered if I should put my wedgy espadrille sandals back on to complete the nicely slutty teen look, but realised that would be bad manners to wear my outdoor shoes in Sinèad’s mum and dad’s posh house with its expensive carpet everywhere. Anyway, I have nice feet, and I spent time giving myself a pedicure the day before, my cute toes looking great in their pink nail polish, matching my manicured fingernails. Dammit, I was looking so fuckworthy, even if I said so myself, this mutt had better fancy me.

When I returned, Sinèad complimented me on my choice of skirt and what I’d done to sluttify my hair and make-up. “Wow Melissa, you look stunning as always,” she said, kissing me lightly on the cheek. Sinèad hadn’t done that before, not with me anyway, and I tingled. “If only the guys at Uni could see you now, they’d come in their pants.”

I smiled demurely. She led me through by my hand to the living room where we both nervously sat on the plush couch next to each other with our old tops on, and the short skirts and our bare legs. Sinèad had bigger and softer tits than me, but I think I had a nicer arse, legs and feet. At Uni, tit guys went for Sinèad, the legs and bum guys liked me.

Sinèad called Zak through and told him constantly he was a good boy, she told me to do the same. As both of us were clapping him his big tail was wagging and he started sniffing about our bare feet and ladylike crossed legs. This was nice and it went on for a few minutes and we were giggling excitedly as his wet nose and tongue tickled with exploring little licks over our toes and legs. Sinèad was rubbing his tummy and down towards his nether regions. All the time we were giving him lots of attention and saying “good boy, good boy.” I could sense he was starting to get frisky, and he kept trying to poke his snout up our skirts.

“He’s responding,” said Sinèad. “Next stage is to lift our skirts right up and open our legs a bit so he can nuzzle around our knickers properly.”

I surprised myself by agreeing. My inner slut was aroused. So we pulled our skirts up to our waists, sat down on the couch again and parted our legs a little to allow Zak to have a good sniff around our crotches. It felt odd and exciting to deliberately not shoo him away from doing this, and to let him sniff away at our private areas as much as he wanted. He then started clumsily licking my fanny through my knickers. The lack of finesse took me by surprise and the naughtiness of not stopping him was hugely exhilarating.

“Ooh, he likes you,” giggled Sinèad. “Just let him do his thing, it’s exciting, isn’t it?”

“Yeah, feels really dirty,” I gasped, letting myself enjoy Zak’s unskilled rough licks and opening my legs a little more, his tail wagging in delight.

Zak’s animalistic panting and sniffling as he lapped at my cotton-covered privates was really arousing. I squealed and held Sinèad’s hand tightly, as my fanny being licked through my panties by her dog was so tickly and rough but it felt so hot and dirty. He was playfully jumping between us getting excited by the scent of our aroused vaginas and we lifted our legs up so he could smell our bums too. I remember deliberately relaxing my bumhole muscle to hopefully increase its aroma which might help get him going. Zak was using his strength to shove his nose all around our holes which were still concealed by our knickers.

Then I got my first sight of his cock unsheathing from his fur like a shiny lipstick, as it grew it looked very red and raw, it was so alien and wet, constantly dribbling clear fluid from its weird fleshy barbed head. Sinèad had warned me beforehand that a dog’s aroused cock is very different from a human one, but I was still shocked to see it for myself.

“Oh my god Sinèad, look at his cock,” I whispered.

“I know, it’s so barbaric, isn’t it? He’s getting really turned on now.” She turned to me and smiled. “This is the last point we can stop as it’s unfair to tease him. If we want to go further we need to take our knickers off, but if we do that we have to let him fuck one or both of us.”

As she said this she reached to touch the cock and began stroking and wanking it and then the disturbing big bulbous knot became exposed. Seeing that weird erect dog penis shocked me, and seeing Sinèad, my best friend from University, tenderly wanking it shocked me more, but the bizarre sight made me ache between my legs. I opened my legs as wide as I could for Zak to slobber over my now sodden knickers again, whilst I debated whether to take the step that would mean no turning back.

It didn’t take me long to decide that I wanted to try to get that big veiny shiny wet alien dog-cock in me all the way up to the leathery ball-sack, including that weird knot thing at the base. I wondered if my tight 18-year old pussy could take that beast, but I was certainly going to try. I had only experienced a few guys’ cocks up till now, and they’d all been too excited and had come quickly, all very disappointing really. I wasn’t sure if I’d ever even been fucked properly. I craved a really hard merciless fuck from something that lasts more than twenty seconds, and I hoped Zak here would desire me enough to want to fuck me properly as a bitch in heat like me deserved.

“Go on, take your knickers off Melissa,” encouraged Sinèad, stroking my hand.

I was losing my inhibitions by now and didn’t care about Sinèad seeing my hairy pussy any more. “Well, I’m not a cock-tease, Sinèad,” I smiled and I lifted my hips and pulled down my panties, leaving them at my thighs. Sinèad told me not to so silly and yanked them all the way down to my feet, and off.

“They’re soaking, you dirty bitch!” she said, and put my pee-dripped, vadge-juice and canine-saliva saturated cotton knickers to the dog’s snout to entice him in to my now fully exposed lightly-used teen cunt. “I’m keeping mine on so he’ll concentrate on you. I want to watch you get licked and fucked by my Zak, you’d better give him a really good cum,” she teased me. She patted my open pubic area, which surprised me, being touched intimately by my best mate, and put her fingers to the dog’s nose. “Come on boy, does that smell good? Come on, good boy, on you go, good boy.” I felt so dirty and used, I fucking loved it. The excitement of knowing I shouldn’t be allowing this to happen was incredible.

He didn’t need much encouraging and started furiously slobbering all around my naked fanny lips and bumhole as I lifted my legs up and spread them for him to get full access to everything. I was getting both my holes licked ridiculously hard by this big dog and it was another level from what a guy can do, the hairs around my labia and anus tugging due to the speed and ferocity of his licking and nuzzling, causing me to gently yelp. I’d never had my other hole licked before, and the first time was by Sinèad’s pet German Shepherd, I was in dog-slut heaven. I relaxed my sphincter as much as I could to let Zak’s tongue and nose fully explore my wrong hole, what a feeling.

“That’s it, give her arsehole a good licking, good boy,” Sinèad looked up at me, her dog intensely lapping away at my open brown hole. “Have you had a shite today, Melissa?”

I mumbled defensively, “Yeah, but I cleaned by bum thoroughly in the shower later, why, is it dirty?” My embarrassment was reaching new levels, but I just went with it, Sinèad had seen everything now. I was always scrupulous in my personal hygiene, especially after doing a number two.

Sinèad looked at her dog lapping away loudly at my anus. “No, he must just be able to smell things we can’t. He really likes licking your bum.”

“It feels gorgeous,” I moaned. “But my fanny wants some more of those amazing licks too.” I rubbed Zak’s head. “You’re such a good boy, aren’t you Zak?”

I shifted myself down the plump couch slightly to close off my bumhole to Zak and I spread my fanny lips with my fingers to expose my engorged clitoris to that slobbering canine tongue. I cried out as the fleshy knub was licked hard and rough without mercy.  I looked up at Sinèad’s dad’s shiny golf club trophies and could see a small reflection of my spread legs with his beloved pet dog panting and slurping loudly at my hairy pubic area. I was starring in my own private extreme porno in this highly-respected man’s family home.

Zak’s panting and slobbering from my cunt to arsehole then back again, combined with his rough animalistic efforts trying to clamber on me was driving my pleasure to astoundingly intense levels. The feeling of his warm fur against my open thighs and private parts added to the perverse raw excitement. It was incredibly dirty and horny, then I realised that Sinèad was down below french kissing, licking and sucking the dog’s angry-looking and dribbling purply red cock, her lips moving from the odd-shaped head with little fleshy barb at the tip, down the long thick red veiny pulsing shaft, all the way to that cunt-churning bulbous knot at the bottom, just above his tight leathery balls. I couldn’t take my eyes off it. She let the grotesque raw looking monster cock fall from her pretty teen mouth, and smiled at me. It was time.

“Zak, good boy, gooood boy, you want to fuck Melissa now don’t you, good boy…” she said, her chin and cheeks glistening from the dog’s precum, before returning her beautiful silky lips to Zak’s dribbling weird cock-head, wanking it slowly into her pout. In between sucks and licks and cock kisses, she said, “Bend over the couch, Melissa. Let him fuck you. I’ll help guide him in if he gets too frisky. You’ll fucking love it.”

“Oh yeah, I need fucked now. I want that big dog-cock up me,” I gasped without hesitation, appalled but thrilled at hearing my own words, and I turned around to rest my face onto the soft fat cushions of Sinèad’s family’s expensive couch and arching my back to stick my bare round white bottom out for their beloved pet to molest me from behind, just as I’d practiced in my dorm room at Uni for countless nights. I knew that my bottom was lusted after by so many guys at Uni, and here I was offering it up to a dog. I felt like a truly depraved slut at this point, and I loved it. Zak was panting hard and I winced as I felt the hard claws on his front paws clumsily scrape on my bare arse and lower back as I presented for him. I didn’t care that Sinèad was there to see it all, I was too fucking horny by this time, in fact it turned me on even more, being watched. I sensed Zak was struggling to get a target and I felt Sinèad’s hands on my backside pulling my bum cheeks apart for him. “Thanks Sinèad,” I said, oddly, as I was completely and intimately exposed.

“Ooh, very nice, that’s horny as fuck,” said Sinèad. “You’ve got such a gorgeous fanny and arsehole, Melissa. Doesn’t she Zak? Who’s a lucky boy?”

I’d never had my backside screwed before and perhaps Sinèad’s pet dog could have the honour of taking my brown hole virginity if he wanted it. I didn’t care which hole he went for, I just begged for his big beast-cock to find one of them. I gasped “Come on Zak, good boy, come and get it. Please Zak, goood boy…”

Sinèad was helping the big dog into position. His front paws were scrabbling up my back and the t-shirt was good advice. I could feel his furry warmth on my bare bum and legs then his panting in my ear and his weight on my back, then the warm wetness of his cock fluid against my brown hole and sopping fanny, then I yelped as I felt his doggy-cock find my welcoming cunt with a plop sound and I immediately felt the heat of his shaft in my walls unlike any guy’s penis I’d had, and he started just hammering away. It was like a jackhammer! Oh my god I’d never been fucked like it, he was nailing me so fast and hard and he just kept going and all his panting and scrabbling was so hot.

Sinèad was egging him on. “Good boy Zak, good boy, fuck her hard, that’s it, she’s your bitch now, good boy!”

I was yelping and grunting and I came so hard but the dog kept hammering away so fast I was having continual little mini-comes. Then suddenly he thrust forward and I experienced the huge bulbous bit hit resistance at my labia. I gasped each time he pushed again and again with more and more force, until my vagina finally yielded. I shouted out in surprised pain but this soon transferred to searing ecstacy as my g-spot was crushed and wave after wave of intense pleasure surged through me as my young cunt tightly gripped this monster dog cock from tip to knot in all its impossible size.

Sinèad shouted above my own loud grunts and moans, “Oh my god Melissa! Oh my fucking god! He’s knotting you, you lucky bitch!” I felt her squeezing my hand hard and I appreciated the support.

Zak’s cock was all the way in me, knot and all, and my whole reproductive system felt incredibly full. He stayed very still and just panted in my ear and I could feel his cock tip nudging against my cervix deep in me, then violently twitching and ejaculating his spunk into my womb. His knot was locked in me and stretching my cunt to the limit and together with his erect cock and his floods of cum, my entire vulva felt at full capacity and almost unbearably heavy. I was still repeatedly orgasming from the knot pressuring my g-spot and I tried not to cry from all the forced comes trembling through my body. I moaned and yelped and whimpered and sobbed “Am I a good fuck Zak? Am I a good fuck? You’re such a good boy, goooood boy.”

I was bent over and knotted from behind for several minutes, Zak panting as his knot continually squashed my g-spot into orgasm spasms every few seconds, Sinèad holding my hand. Each time I came, I was curling my legs up so the soles of my feet were going deep into the warm fur of his rump and slamming the hard muscles of the dog’s behind and held them there until my orgasm subsided, when they limply dropped down again. But only until I was forced into another come a few seconds later. I went from sobbing to crying at this point. This only added to the sensation of being taken roughly by a relentless beast. I’m embarrassed to admit I accidentally urinated too, a distinct warm wetness splashing onto my thighs and a watery tinkling sound on the carpet. I was struggling to control anything.

“I’m really sorry, Sinèad, I’ll clean it up,” I sobbed in between gasps and in total shame of my humiliating and filthy sluttery, tears and mascara and eye-liner streaming down my screwed up face. I was a fucking mess.

“Shh, it’s fine, you dirty cow,” she laughed and squeezed my hand hard. “We can clean it all up later, just let it all go, shhh, you’re doing great honey.” What a friend she was, letting me piss all over her mum and dad’s posh thick carpet whilst her pet dog fucked me into a quivering orgasmic oblivion.

I was sporadically crying and shaking, my tears not only coming from the continuing forced coming, but also from my shame at having a big dog panting on my back, having given it my prized, tight young cunt to bury its enormous cock in, all the way up to the balls, knot and all. I just lay my head on the sofa cushion which became damp from my tears and quietly whimpered, constantly coming whilst looking at a lovely framed family photograph of Sinèad, her sweet mum, proud dad, and older sister with Zak sitting nicely between them all. It was an odd feeling, having my best friend’s respectable family smiling down at me bent over their couch as their cherished pet dog subjected me to a punishing stream of never-ending orgasms with his big cock with that ginormous knot straining my poor inexperienced and stretched fanny. I was so relieved their pet didn’t go for my virgin arsehole, I don’t think I could have taken the beast up my bum. I found out later that their darling younger daughter Sinèad had guided him into my cunt, and I thanked her for it.

Sinèad was now gently stroking my hand and my face, wiping away my tears and her soft voice soothing me “Shh, you’re doing great Melissa honey, you’ve given Zak such a good cum, really good. Deep breaths. That’s it, good girl. It’ll be over soon.”

I had this sudden feeling that Sinèad’s neighbour, pervy Mr Jones could well be peeping through the living room window hoping to see Sinèad and I in some teen lesbian fantasy. He’d be in for a shock if he saw his lovely next-door neighbour Sinèad half-naked, helping her gorgeous brunette friend Melissa from university take a hard fucking from the family dog in a pool of her own piss, continually coming whilst crying her slutty eyes out. Oh well, I hope Mr Jones enjoys his unexpected ultra-hardcore teen treat, and has the best wank ever.

Eventually Zak’s cock softened slowly releasing his knot from my trembling innards and I heard a long, wet and very loud fanny fart sound which was all his dog spunk and my cunt juices rudely slopping from my gaping vagina and splashing onto the damp puddle of pee already soaking its way into Sinèad’s mum and dad’s deep-pile living room carpet. Zak jumped off me and sprang round to my rear end to slobber away noisily at my slicked anus and well-fucked swollen, soaking and very tender cunt. I could feel a mixture of forced intense pleasure again rushing combined with the sharp pinching of my matted mass of pubic hair being pulled as he nibbled and licked at the gunk streaming from my fuckhole.

It was all too much and I pushed the animal away and collapsed onto the filth-soaked carpet, covering my t-shirt in Zak’s gloopy dog cum and my pussy juice and urine cocktail. I was helped up to stand by Sinèad. Our bare feet slipped in the mess on the carpet, which squelched up between our toes and oozed over our girly painted toenails. We laughed and hugged each other tightly, our t-shirts sticking together from the disgustingly sexy doggy and human goo. I decided to take off my soiled t-shirt, but in doing so, I succeeded in accidentally smearing some of the foul cocktail onto my face and hair. My degradation was complete, my face being a sticky mess of drying tears, running mascara and eye-liner, vaginal fluid mixed in with my urine, and dog-cum. I could feel it – and taste it – all caking onto my face as it dried, and I fucking loved it.

“You’ve got lovely little tits,” said Sinèad, eyeing my naked pale 34B’s, their nipples sticking up proudly. I think she wanted to feel them, and I wouldn’t have stopped her, but she didn’t.

I was naked, covered in the aftermath filth of sex with a dog, and entirely unselfconscious. “Thank you both,” I sniffed, looking down at Zak giving him a clap and a cuddle, as another stream of his cum dribbled down my bare legs. “What a good boy, that was incredible. I have never ever come like that before, you big gorgeous thing.”

I’d just had the fuck of my lifetime in this nice family’s living room from their pet dog in front of all the family photos, helped by their beautiful daughter Sinèad, who was now desperate to offer her own sweet teen holes for the beast’s pleasure too. I watched her slip her knickers off and could see her exposed fanny was even hairier than mine. This was the nineties after all. She spread her legs wide and rubbed her clit area saying “Zak, Zak, over here, come on boy.”

I wondered if Zak might be too tired after banging me relentlessly just minutes before, but he was quickly burying his snout into Sinèad’s enticing fresh young bush. “Suck his cock, Melissa, make it nice and hard for me,” she gasped whilst rubbing Zak’s head as he loudly sniffed and lapped at his second teenage human fanny of the evening.

I guess it was my turn to experience a dog’s dick in my mouth for the first time, so I did the decent thing and got down into the puddle of mess on the plush family living room carpet to position myself below Zak’s hind legs and started to kiss and lick his rapidly expanding meaty red cock. I slowly teased the dribbling weird fleshy barb with my tongue and popped the head into my mouth whilst slowly wanking his shaft, slicked from his cum and my own cunt juice, which made the metal rings on my fingers glisten. To think, that mouth you have kissed so many times darling, has been all over a dog’s cock and balls. The hot saltiness in my mouth took me by surprise but I worked through it like the good little slut that I now was. I then gently massaged and kissed his knot and even tried to lick his anus, it just felt so natural in the moment, but I couldn’t reach it in the position I was in.

Whilst I was underneath Zak with his heavy cock dangling into my mouth and dribbling all over my already messed-up face, I thought of the possibility of creepy Mr Jones peeping through the living room window again, perhaps with his wrinkly middle-aged cock out. Maybe the dirty old bastard was filming it on his Handycam for his mates down the pub. I opened my legs wide and used my fingers to spread my swollen pussy lips for the imaginary camera. In fact, Mr Jones, if you’re there, come in and lick the dog-cum still oozing from my sore cunt, I know you could only dream of tasting and smelling my tender young fanny and arse. I hope your dirty old men mates in the pub enjoy your homemade obscene pornographic video of two attractive and horny girl-next-door teenagers enjoying and sharing some dog-cock. Just don’t let your ugly old wives see it.

I was in totally lost my mind slut mode, actually hoping that Mr Jones could be at the window watching and filming the depravity of Sinèad and I sexually pleasuring her dog, but later being thankful, of course, he wasn’t.

Sinèad invited me over several more times whenever her parents were away, but I declined. I think my shame got the better of me, but I didn’t regret that one-off experience. Sinèad and I remained best friends throughout university, although we sadly lost touch once we left and went our different ways.

So, my darling husband David, I’m glad you found this letter, I’ve wanted to confess to you for so long about the time I was fucked senseless by a big dog. Now you know why my favourite position is being hard-fucked from behind by you. And yes, I’d love one of those doggy dildos, and for you to knot me with it, woof woof!

I love you darling, Melissa xxxxx
