Unnatural Behaviour
By Zipper.
Maybe she’d lain too long in the garden and was getting sunburn. She opened her eyes to see.
“Biff! … No!” He was licking between her thighs, acting like the silly dog he was! She brought her knees together against his thick hairy body, and when she squeezed his muscled chest, it made a sharp little thrill shoot up her backbone. But he continued to lap at her cunt.
“Biff!” she said softer, “Please stop that right now!” But she didn’t mean it. His snout snuffled deeply into her swimsuit bottom, increasing the pleasure in her snatch. Her heart beat harder as she lifted her butt and gave a wiggle as she slid the bikini bottom down!
Tugging the towel down over herself, Selina allowed herself to feel that it wouldn’t hurt to let the horny dog have his way! She quickly made a tent of the oversized towel and spread her knees so Biff could stick his soft wet muzzle back into her crotch. “Oh – Yes!” she gasped.
Biff had been eager to get his big wet tongue on her soft-haired pussy since she’d begun getting her periods! When her mother caught Biff at it, she would yell, “Watch out for that dog, Selina! You have to slap him down when he does that!”
But now, as the dog licked right inside her pussy-lips, Selina arched her back and moaned, “Ooohh, Biff!” He’d never been that far before, and the sensation felt wild and crazy. His tongue shot a fire up her cunt, and she began to roll her ass in ecstasy. Maybe Biff would lap her long enough to make her come? She trembled at the erotic thought.
But Selina kept her head enough to look around quickly and peer into the tall hedge that separated their garden from the neighbors. But no, it was clear and peaceful, apart from the slurping of Biff’s tongue working into her pussy and the whining deep in his chest.
However, Selina was mistaken. She was being watched.
But Biff was getting to her like a finger-fuck never had. Selina reached beneath the towel and shoved his muzzle deeper into her snatch. She rolled her hips and humped her juicy cunt in a jerky fashion against his muzzle. Her arousal was gathering pace, and the reality around her receded into an erotic swirl.
She suddenly gasped and quivered,
“Oh, Biff!” she panted, swinging her head from side to side and breathing harshly. Her fingers dug into Biff’s broad head as she began to climax.
“Oh, Biff – you’re making me – Cum! You – Big – Horny – Dog!”
Her eyes rolled back in her head and her teeth locked into her lower lip as she rode out the rapture.
Then she fell limply upon the grass, weak and spent, her small tits heaved while her mind gradually returned to earth.
The dog’s big head came up from under the towel, and Selina helped uncover him but then was sorry she did. She suddenly recoiled in shock as she felt the prodding of his cock against her cunt!
She ducked her head down to see, and she was stunned!
Biff’s huge red cock was blindly poking at her wet entrance!
She wiggled and struggled to push him off. But Selina only succeeded in bumping her belly up against his firm chest!
Biff clung on, humping and thrusting forward steadily. It slid across her hairy cunt mound, and she bucked wildly beneath his weight. Panting, she had to turn her head aside from his dripping tongue, and the move threw her crotch into his moving prick again. It was slippery, oozing liquid. Her pussy was slippery, too, skidding under the intensity of that stiff dog cock.
Suddenly it poked into her pussy-lips. Selina quivered sharply and tried to wiggle off its end, but he kept humping, and somehow it suddenly went into her cunt! Right between the lips that had been turned so slippery by his licking and poking right up into her where only her finger had ever been before! “No! No!” she cried.
Selina was scared. She clawed at the big, powerful dog, and her curled fingers only slid down his short-haired hide. She tried to push him up with her knees, but he was too heavy, and his cock penetrated deeper into her snatch. Now it hurts like hell, like crazy, and she was just about to scream but fought back the panic just in time.
Mom wasn’t home, but the neighbors probably were, and she didn’t want any of them to come running to catch her being screwed by Biff. She’d have to fight Biff off by herself before his huge prick ripped her cunt wide open, made her bleed, and took her cherry!
Selina wrapped her arms around his heavy neck and tried to wheel him off to one side, but the dog had the feel of her inner pussy now and would not be denied. He humped his back and rammed deeper into her tightly resisting cunt. Selina felt the cock-head strike against something elastic, against some buried membrane that stretched and pained.
“Biff!” she hissed. “Get off me! Stop that! Biff!”
He was too far gone to listen. He only squeezed her surging body tighter between his paws and pounded that insistent prick more strongly against the barricade of her cherry.
“N-No!” she grunted. “Oh, no, Biff! Don’t-do-it!”
But she couldn’t get herself free, couldn’t loosen the impaling cock working like a lance into her pussy. And the pain, quick and sharp and over in a single flashing moment, now she felt the slick dong moving and the swelling of the knob on the end of the dog’s hungry cock. Now she knew the deep tickle of a prick within her cunt, where she had imagined one would be before too much longer.
But the future was now, and she wasn’t a virgin anymore. She felt the extra wetness of blood and thought crazily that being screwed by her dog wasn’t exactly the way she had pictured losing her cherry. But at least Biff couldn’t knock her up, and since it was already done and she had tried like hell to stop it…
Biff grunted and shoved. His cock rammed into her cunt to his hairy balls, and Selina knew that her snatch could take it all without ripping, that her tightly clenching pussy could swallow every swollen inch of the dog’s big prick without tearing.
And his cock felt terrific. It felt so wonderful, buried deep in her cunt, and for the first time in her life, she knew the joy of being fucked.
All those sex-education classes, girls giggling, and wet dreams led to this crazy moment. His big rod felt marvelous, filling her pussy and making her ass go tight!
Biff humped in and out of her cunt eagerly, and the thrill of that swollen prick slipping over her vibrant clit was almost too much. Selina thought she was going to faint.
Oh wow! she thought. Biff’s thrusts were making her head bob up and down. She had to have something to hold onto. She clung to his neck while getting her ankles over the dog’s back. Now she could work her crotch against his thrusts, swinging her ass in quickening circles while on the verge of cumming in her very first fuck, and when he plunged his dick again, she quivered in ecstasy.
Selina came, clinging to his body with her legs and arms. Lights flashed on and off within her head, and crazy things happened inside her cunt. Her rectum snapped tight like a rubber band, and she felt his balls swinging.
Biff whined then, his breath hot in her car and his damp muzzle pressing against her cheek. She felt her tits rubbing their erect nipples into his heaving chest and the rise and fall of his hairy belly as he shoved the prick to her cunt in a savage burst of power.
He shot his load off inside her.
Selina trembled from head to foot as hot dog sperm spurted from his swollen cockhead: thick and creamy, it flowed with a few drops oozing from her rubbery cunt-lips to puddle in the crack of her steamy ass.
Blissfully, Selina rolled her crotch, the hard cock inside her frothy cunt, and over the aching button of her clitoris.
Moaning softly to herself, clenching her teeth, she heaved her pussy against Biff’s balls. She burrowed her stiff nipples into his muscled chest and moaned softly, with the craziest feeling blossoming within her.
“Oh, Biff, you lovely, wonderful dog, with such a lovely cock! My very own cock!”
As if in answer, Biff gave the last spurt of hot jizz, and Selina reveled in the buttery sensations within her flexing pussy. The dog’s cock was her own. She possessed it in her pussy and held it prisoner, by the muscles of her cunt, and it pulsed inside its tender trap.

Selina lay back in the hot water of her bathtub and smiled smugly. She wasn’t an eighteen-year-old virgin anymore! She’d had full-on sex!
Soaping the sponge, she slid the bubbles over her tits, tickled them awhile, and wished they were more like her mother’s, who had a fine figure and was still an attractive woman.
But Laura, her mother, seemed to disguise her good looks by wearing boring loose blouses. Selina guessed she didn’t want unwanted male attention since she’d become a widow. Maybe she still loved the memory of her husband Richard and didn’t want to have shameful sex with another man?
Her father had seemed a distant guy, seldom home and away on business. The highway had killed him two years ago, and his mother became a widow. A while after dad died, his mother obtained Biff from a recommended dog breeder. She’d specified a home companion and guard dog, which would help fill the void left by dad’s departure. And true to form, Biff became his mother’s most loyal friend.
Tentatively, Selina eased the tip of her finger between the plump lips of her cunt. It still felt beautiful, but had it altered now he wasn’t a virgin? Had Biff forced her pussy out of shape or made it looser?
She didn’t know about these things? If she dared ask Laura about such things, her mother would probably blush or turn away and consider her whorish. Suppose she went right up to her saying: Hey, “Mom, Biff has been fucking me recently, and I want to know if….”
Selina slapped the water’s surface with her open palm, imitating her mother fainting. She smiled at the thought and climbed from the tub.
As she dried herself, the fluffy towel felt sensitive to her skin. Every fine hair on her arms and legs seemed to stand up. She wanted sex again right now.
Then quite unexpectedly, her mother entered the bathroom! She stood for a moment staring at her naked daughter, holding the bath towel. Her facial expression was one of displeasure! Selina was perplexed, and even more so when her mother stepped forward and soundly slapped her face!
“Yes! I saw you with Biff from my bedroom window, you crazy brazen bitch!”
As the sting of the slap spread across her cheek, Selina saw anger in her mother’s eyes she’d never seen before.
“You just had to let Biff fuck you, didn’t you! I knew this would happen – But I won’t let you steal him from me – do you hear me?”
Selina was shocked and rigid. Her mother had never before slapped her face or used such language! Dismayed, she cried, “Laura! No! I tried to stop him – really I did!”
Tears sprang to her eyes, and her only response was to embrace her mother and weep on her firm bosom. Laura took her into her arms, and they held each other. Their warm bodies pressed together. The closest they had been since Selina was a child, but Selina now was nearly the same height.
Laura gently moved back and took off her soft sweater top.
Her hands dipped behind, and she released her gorgeous breast from their bra. Her nipples visibly stiffened as she stood before her naked daughter. The sensuality of the moment overcame Selina. Their bare breasts met, and she passionately kissed her mother’s mouth.
Laura then led Selina to her bedroom, where they made love, their mouths feeding hungrily on each other. Laura ground her juicy cunt against that of her daughter. They moaned and whispered secrets about Biff as they explored each other.
Laura then cradled her daughter’s head while softly explaining how her sexual affair with Biff had begun.
“It was his unnatural sexual behavior that gradually excited me, Selina. It enticed me into teaching Biff to do things for me in the bedroom, like lapping at m yvagina. I felt so ashamed to start with.
But discovering what Biff hid between his hind legs excited me … a fabulous cock! And with a little hand or mouth encouragement, it would spurt hot spunk!
Something I hadn’t had for a long time since your dad went Selina.
I stopped short of full-on sex with Biff for quite some time before … finally giving in to him.
The first full-on fuck I had with Biff was an evening you had gone to the cinema with your friends Selina … leaving me alone with Biff.
I felt fresh and tingling from the shower I’d just taken and had been drying my hair by the fireside in the parlor. Just contemplating what I was about to do with Biff was turning me on, and I couldn’t wait any longer.
I took off my bathrobe before lying back to let the heat of the fire onto my skin.
Then I called Biff over to me. I trembled excitedly, watching him wagging his tail, his eyes fixed on me. He was a handsome muscular mutt with a sleek brown-black coat. With his warm hairy coat against my skin, I shivered excitedly. The pure intimacy of the moment was intoxicating. My cunt tingled. Then tentatively reaching into his warm brown loins, I began stroking and fondling his silky black sheath, whispering, and cooing encouragingly as I did so. Soon I felt a throbbing in my hand. Biff was now letting out soft wining calls of desire that thrilled me. His sheath was expanding in my hand, and his red-tipped cock glistened as it emerged provocatively. I’d begun perspiring from the obscene urges running through me. I knew these urges were taboo and wicked, Selina: but I felt a bravado and fear about them. I couldn’t even begin understanding my desire for Biff.
While I was focused between his loins, Biff was also exploring mine. Then I felt his wet nose pushing rudely into my pussy, causing me to pant in pleasure, and just like you in the garden with Biff earlier, I was fast losing control. Biff was now sexually agitated, too, his fat glossy cock wagging obscenely in my face. Instinctively I cupped my mouth over it. It felt like heaven. His snout gnawed into my cunt, his teeth nipping my clit, his tongue slurping my juice. I was near the climax, and Biff was sweating profusely. With a genuine cry, I knelt hurriedly on all fours for Biff to mount me. Biff needed no prompting from me. With a cursory sniff at my cunt, he was on me. Oh, that sensation of contact, his hot chest against my naked back, his strong paws encircling my waist, his panting head alongside my own.
My eyes closed in wild anticipation. And then the bliss of union. Biff is suddenly penetrating me: hard and deep! Selina was panting with excitement at Laura’s tale. Her mother’s fingers had now entered deep into her vagina to bring her to a climax while she brought the story to its conclusion.
“Biff then pumped at me with a blinding pace … my mind span in ecstasy.
Now, sensing he was nearly there, I screeched with passion. I climaxed savagely just before he did: an incredible blinding moment. My legs and arms shook as his stuff spewed deep inside me! Selina let out a loud cry of passion as her mother brought her to a shuddering climax.
“That’s it, my darling … let it all out for Laura,” she purred.
*****
My heart had sunk when I glanced from my bedroom window and caught Selina bitching with Biff in the garden. The pair of them were having a ball, much to my disappointment. For some while, I’d realized that as my daughter developed, so too had Biff’s sexual interest in her! Occasionally, I’d observed Selina pretending not to notice when Biff poked his snout up into her pussy! That little bitch enjoyed it! What was a mother to do with such a wayward girl? What annoyed me was that I’d only blame myself shamefully. I had trained Biff to do it for my pleasure. Not for Selina’s! I felt humiliated. It felt like my love was being unfaithful to a younger tart!
You see, I had been a sexually starved widow of thirty-four. I’d desperately needed some sexual activity. But nothing would induce me to become part of that humiliating meat market called “ the dating game.”
Ugh! No, my only companion at bedtime had been Biff, and one evening, as he lay beside me while I was reading a novel in bed, I became aware of Biff’s stimulated arousal. It was a gorgeously throbbing six-inch cock, and I was astounded by it! The sight of it was enough to turn me on. Then the idea of indulging in unnatural behavior with him engulfed me in a shameful excitement. I slowly placed the book down and began using my hands to explore his belly and leathery sheath gently. And as I did so, Biff panted with evident pleasure. Just contemplating what I might do with Biff thrilled me. I took off my bathrobe before lying naked against my pillow and coxed Biff onto me! As his warm hairy body came up against my skin, I shivered with excitement. The pure intimacy of the moment was intoxicating, and my cunt tingled.
Then reaching into his warm brown loins again, I began stroking and fondling his silky cock, whispering, and cooing encouragingly as I did so. Soon his cock was throbbing provocatively in my hand! Biff was now letting out soft wining calls of desire that thrilled me. I’d begun sweating from all the obscene urges running through me! Yet I felt a bravado over what I was contemplating. While I was focused between his loins, I felt his wet nose pushing rudely into my pussy, causing me to pant in pleasure, and I quickly lost control. Biff’s glossy cock wagged obscenely in my face, and I cupped my mouth over it almost instinctively. It felt heavenly as its length slithered back and forth with Biff’s humping action.
His snout gnawed into my cunt, his teeth nipping my clit, his tongue slurping my juice. I was soon on the point of climax! Then as his cock expanded and spewed, I screeched – teeth grinding tsunami of ecstasy. The sexual intensity had been more significant than anything I’d experienced as a married woman, which only increased my sense of shame, as my husband had always been a dutiful and considerate lover. But such sentiment did not sway, as Biff’s incredible ability in the bedroom soon became a regular procedure for guaranteed satisfaction. And before long, I knew it was good for me when out meeting acquaintances. They would remark on how cheerful and attractive I’d become of late, pleased that I was facing up to life again! Yet now, my sex life is under threat from my daughter!
I’d seen them together in the garden. She is in her skimpy bikini, supposedly sunbathing, while Biff sniffs about. Brazenly then, as I watched, she’d let Biff fuck her silly! Such unnatural behavior for a teenage girl! My worst fears had been realized Selina had led Biff astray, and I was resentful. I’d pondered what had happened between us when I confronted her in her bedroom and how slapping her face had had the strange effect of not only sexually exciting her but also myself. That one stinging act of slapping her face had torn through formalities. It revealed savage sexuality was possible between us, one of a dominant mother ravishing her naked daughter into sexual submission.
So the way forward with Selina begins to fall into place the prospect of further indulgence emerges, of punishment and pleasure. Yes … of course, Selina would continue with the delights of bitching … but she would need to acquire the correct etiquette. She would need instructions from her mistress on how and when to satisfy the dog. Oh, there was humiliation and tears for her naturally. But eventually, there would be moments of satisfying bliss for her and her mistress.
The End.
