As ordered my 18 year old sister was stood erect and naked in the middle of the room she'd grown up in, the happy gleam in her eye partly due to the unexpected opportunity for play that had been given us with our parents' announcement that they were going out for the evening and partly due to the fact that she was eight months pregnant and her swollen belly matched her swollen breasts in their appeal to me. The fact that I had taken her as my willing submissive slave eight months previously and had been filling her with my incestuous seed at every chance since was no co-incidence to her present delicate condition. That I was the proud father was also beyond doubt considering I'd taken her virginity shortly after her 18th birthday and, despite her natural wantonness, I was still the only man she'd been fucked by as befitting being her possessive Owner... Her slutty instincts I'd allowed to run free in her bisexual tastes and she seemed content with the arrangement, in fact being so beautiful and flirty with a deviant imagination to match my own she was extremely adept at seducing other girls or older women and bringing out their lascivious sides. The fact that she now stood expectantly and heavily expectant before me made my heart beat faster and my erection lurch in protest at its confinement in my trousers. Since her pregnancy became obvious our relationship had taken on new heights of depravity. When she first surrendered herself sexually to me all those months ago it felt instantly right to use her as I wanted and she took to being my 3 hole whore with an enthusiasm that made my senses swim... She dedicated herself to her education in deviant sex and the unique pleasures of BDSM with an insatiable zest and was never happier than when my cock was pounding her cervix and filling her womb with heavy loads of cum. Thoughts of contraception never entered either of our minds since the relationship of Master and slave felt so natural... and so nature followed its course and my sweet angelic slut sister was soon impregnated. She rose to this unplanned development wonderfully, tearfully spinning a convincing story of an unknown boy at a student party being the father; a tale performed so well that our parents' shock and disapproval was wiped away instantly and her caring big brother entrusted to protect her virtue in future. Since I was her Owner and intended to continue to ensure that the only cock she enjoyed was mine I accepted my responsibilities easily, especially since it meant that the unusual amount of time we spent in each others' company went unquestioned by our mother and stepfather, who hardly expected that we could barely contain our perverse lust for each other. My sister had been an eager debauchee since that magical weekend I first took her as my possession, but pregnancy had intensified her need for hard physical sexual gratification that was bordering upon nymphomania; the hormones and other natural chemicals pounding round her young body had her radiant in more ways than usually associated with the delicate condition and I had been doing everything possible to defile the purity of motherhood-to-be. So when the opportunity to have the house to ourselves arose every minute was to be savoured.... Hence the instant the parental car pulled out of the drive I'd produced her collar, fastened it round her slender neck, and ordered my sibling slave slut to go to her room and prepare herself. Such was the conditioning that she'd surrendered herself to that the very act of putting her in harness began her descent into her aroused sub-state and now running an approving eye over my sister's pale nakedness, still slim except for the rounded swell of her smooth belly, I was delighted to see the glistening torrent of female fuck juices already leaking from her engorged cunt....exposed and shaved clean as it was on a daily basis. This lewd appraisal of my precious pain whore had my erection stirring, painfully trapped inside my trousers and I wanted to sink it deep between her soaking thighs where I belonged, but I held my rising lust in... The truth was that my sister was just too delicious to not tease and torment into a deranged passion. I raised my eyes up from the intoxicating folds of her freely flowing cunt and with a smile observed that her breasts were following suit... My clever sister just couldn't wait until the birth to start expressing her mothers milk and had joyfully induced the lactation early by using suction cups on her sensitive nipples... Now, in her perversity, sexual arousal started them leaking in the way that a baby's crying would normally The hours of dedicated playing with her tits was paying dividends in a way that excited us and had proven an unexpected attraction amongst her more bold girlfriends. If we'd had more notice of our free run of the house I'd have instructed my slave girl to invite a couple of her female lovers over; the look of bliss on her face when she breastfed them was only beaten by the inevitable straying of their hands to her splayed thighs and the orgasms they forced upon her without relinquishing the enlarged teats they feverishly suckled upon. However, tonight she was mine to enjoy alone and her clear blue eyes sparkled at the prospect. Keeping that beautiful fresh face staring expectantly into mine, I strolled provocatively close to her body until her protruding belly was touching the strained yet concealed by pants erection that had placed her in this condition. I pushed my groin forward slightly so she could feel my hardness against her curved stomach and she groaned appreciatively and shifted her body weight artfully to rub the incestuous fruit of our unnatural relationship against her Master. She certainly knew how to ignite my lust and I grabbed her flame-coloured tangled locks at the nape of her neck and forced her lips to mine roughly for a long overdue passionate kiss that soon had our tongues dancing against each others' in an imitation of my hands gliding forcefully down her spine and kneading her pert buttocks in a way that had her thrusting her pelvis towards me in a vain effort to crush her rigid clit against my clothed body for relief. Unfortunately, her occupied womb wouldn't allow freedoms she'd enjoyed in previous months. As I lost myself in the smoldering effects of the kiss, I realized how wrong it was for me to still be dressed and be denying myself the sensuality of holding her naked against me, so returning my grip to the convenientleash that was her hair I eased her head backwards and broke the spell that locking lips with my sister always inspired. "Undress me, slave," I said, these words breaking the silence that had been maintained throughout apart from the heavy breathing. "Yes, Sir," she answered demurely and without hesitation reached down to unbuckle my belt and unfasten my trousers....she had her priorities fixed in her mind as usual. I allowed her to unzip them so they were free to fall to my ankles and, ignoring the blatant bulge in my underwear, I lifted my arms in indication that she should lift my T-shirt over my head next... a hint that she complied with. Once my upper torso was as naked as hers I stepped out of my trousers and took her tiny hand and placed it over the erection shaped tent pole straining for release... I guided her fingers along the cloth-covered shaft and made it linger at the end of the protrusion so she could see the effect she had on her brother. As usual when she got me this hard she inspired a flow of pre-cum which whilst modest compared by her production was still enough to have made a spreading dark circle in my underwear. Her fluttering fingers sent electric thrills across my sensitive cockhead as she swirled the slippery cloth against its swollen bulb, then unbidden she dropped to her knees and lapped at the sticky mess... Well she'd made the mess; it seemed fair that she cleaned it in the best way available. I felt the warmth of her saliva soak back through the material as her tongue swirled as best it could at the concealed length of prick meat and I could resist no longer... I pulled my underwear down and my rock solid erection sprang up triumphant at its final liberation... Grabbing her hair once more, I pushed her face into me and was rewarded by the unique feeling of my slave's soft, wet, and welcoming mouth encasing my bobbing knob end, her well practiced lips dragging my foreskin clear of my bulbous purple cock-end in the process. The familiar tingling warmth spread down my shaft and throughout my whole body as my orally inclined sister worked her dedicated devotion upon me, recklessly driving my erection into her throat without regard for her own modesty. She was eager to please her Owner and knew how to fuck me with her mouth, but as usual having my pregnant slut naked on her knees below me had my more fierce lusts raging and I wanted harder gratification. "Enough, slave," I barked and she instantly withdrew her angelic face from my groin and looked up at me expectantly. If she didn't recognize the wild look in my eyes she certainly knew that tone in my voice and what would be in store... She wouldn't be allowed to make me cum until I'd extracted my fill of perverse pleasure from her still slender and extremely fuckable impregnated body. My enslaved sister rose to her feet without being told to do so and stood upright once more, her poise to compensate for her extended belly meaning she unconsciously arched her back and thrust her lactating chest out proudly. Spontaneity was always the secret to keeping Domination fresh and seeing those unusually full breasts displayed so innocently, all rounded and firm and tempting decided me on how I wanted to warm my pain whore up. I glanced over to my darling sister's dressing table; obediently she'd laid out all our favourite instruments carefully once she'd been given the order to make herself ready in her room. With slow deliberation I walked over to the ever expanding collection of contact play implements and picked up the smallest flogger... with what I had in mind I wanted to be able to stand in close proximity to my abused sub. Her eyes glistened with undisguised licentiousness as I showed her my choice—the flogger was her personal favourite dispenser of chastisement, as she'd once breathlessly confessed after a particularly energetic punishment session, its stinging caress was like having her whole body fucked at once. I gave the flail a test flick into thin air and her gaze traveled to her Master's face expectantly; maintaining eye contract I moved back to stand in front of her. My slutty slave really was irresistible and I allowed myself the luxury of another long lingering kiss, in doing so taking hold of her collar with my flogger still gripped in my fist and pulling it backwards to ensure she remained at the correct ramrod posture. Our tongues danced madly against each others' as my rampant erection poked up against the belly bulge it had created, the heavy stream of my pre-cum making its contact slick and surprisingly arousing on my sensitive cock-end as my free hand naturally found itself straying to her literally overflowing breast to take a jutting nipple, wet with precious mother's milk and pinched it firmly to enjoy the effect it had on the urgency of my sister's mouth locked against mine. Without warning I let loose the hold on her collar and in the same action swung down with the short handled flogger ensuring its tails stuck hard across her tight buttocks; the unexpected contrast in caresses made her squeal and break off the kiss without permission. Recovering her submissive composure instantly she realized her transgression without me having to say a word. "Please forgive me, Sir, I wasn't ready for the blow," she said meekly, which was perfectly true but I wouldn't be any kind of Dom if I let such things go unpunished and, besides, I knew my pain whore was aching for harsher treatment. "You're my good slave, but you must learn respect," I taunted her and the contrite expression on her lovely teenage face almost moved me to forgiveness... if only I wasn't so primed with vicious Domineering lust and the knowledge that my incestuous slave was aching for painful indulgence. Taking a step back and losing the delightful sensation of warm impregnated flesh against my cock (although a sticky thread of my pre-cum kept us connected briefly I was amused to notice....a perverse umbilical cord from her pronounced stomach to my bobbing erection), I let the fact that harsh chastisement was imminent sink in, allowing the tension to build as my wanton sister let her demented imagination run wild. What she anticipated I'll never know, but I certainly caught her off-guard with the sudden strike I made with the flogger aimed at her maternally prepared breasts, the leather straps hitting firm tit flesh with an obscene smack. My sister flinched under the assault upon those most taboo of targets, but held her position well. I placed the flogger's handle under her chin and gently pushed her head back with it. "Chest out and stand up straight," I ordered kindly and without warning took a second brutal swipe at her already reddening chest, the flail's cruel caress catching hard nipples and tender aureoles this time as I'd found my range. A shudder of excruciating pleasure seemed to ripple through my masochistic sibling's lithe except for the midriff frame and she bit her lip as if to stifle any moans that I might judge disobedient. However, the bright wildness shining her eyes and the way her parted thighs were running with viscous fuck juice left me in no doubt at her increasing state of arousal. The third embrace of the flogger across her tortured tits actually brought a small spurt of breast milk squirting forth, a development I had not expected but which obviously delighted us both. I had watched and participated in my sister's determined exercise to induce lactation prematurely but this was the first time that I'd witnessed such a deviant display... It was as if I'd managed to corrupt and defile her most natural bodily reactions, a living testament to my complete Ownership of her. I repressed the compulsion to bend my head down and suckle upon those leaking hard knots; my deliciously depraved sibling was absorbing her cruel punishment too well to discontinue it so soon and I'd have to be some kind of a sadist to deny her this painful treatment. However, there was a powerful surge of twisted lust rising in me... I was regretting my haste in choosing my sister's bedroom for this rendezvous—I should have used the basement. I knew from past happy training sessions how useful the low ceiling beams down there were; my pain whore would have looked stunning strung up arms above head and fully exposing her tight supple pregnant body to the flagellation she was now enjoying. Still faint Dom never won fair sub and I must take full advantage of the current situation. Besides, we should have enough time tonight before the parents returned for me to lead her on all fours down the stairs for further debauchery... Being impregnated had increased my sister's sex drive to insatiable levels and her cravings were not so mundane as wanting to eat unusual foods. With the thought of a subterranean second round later, I quickly snatched up an ever-present length of black rope that we kept within reach and ordered my slave to put her arms behind her; she'd looked too comfortable with them hanging by her side and I suspected that a few more blows and she wouldn't be able to keep her active fingers from straying to her aching, rigid clit. I wanted her to feel the reassuring security of being bound and helpless under my chastisements so I tied her wrists together in the small of her back with practiced ease, then took a couple of slaps at her irresistible rounded buttocks for good luck. I then stood in close proximity to her back so I could reach round and fondly capture a breast in each hand; they normally were the perfect size to hold fully in my cupped hands but I enjoyed their increased mass also, so firm and perfect with the added sensation of warm mother's milk dribbling over my tweaking fingers as I pulled her against me. As I massaged her tortured teats with the familiarity of Owning her I lent forward enough to nuzzle and bite upon her slender neck and this double stimulation obviously had its desired effect for she brazenly began to stir her bound hands and desperately reach out her fingers with some difficultly to stroke at my rock hard erection that was smearing sticky pre-cum against her back. I allowed this pleasant interlude to continue a little while then relinquished my milking grip on her leaking tits and move once more to face her. My teenage sister looked even more adorable in the prone bound position, the reddened breasts streaming white seepage that had cascaded down onto the smooth curve of her protruding stomach and was dripping to her pretty toes in a mirror of the copious flow of girlie fuck juice flowing freely from the engorged folds of her pouting cunt. I was struck with the sudden urge to coat her entire beautiful body with a concoction of bodily fluids: Milk, cum, saliva, sweat and female lube... Make her glow and shine with a wet sheen of lustful outpourings. To that end, I reached between her flawless thighs and scooped up a sticky load of her natural nectar, smearing her fascinating tits with the precious liquid and mixing it firmly into her milky nipples until her chest shone with perverse moisture, a concoction that I would not deny either of us tasting. I thrust my fingers into my sub slut's mouth and felt her tongue eagerly lap away and I caught a bobbing nipple between my teeth and chewed at it whilst enjoying the tangy, heady flavour. As I suckled and bit at my lactating slut's breasts I cursed myself for being distracted so easily, but my slave didn't seem to be complaining. I, however, was getting aroused beyond self control, which is not healthy for a Dom to allow himself, so I drew my teeth along the fat, stiff nipple and disengaged my oral grip. Retrieving the flogger I consoled myself that the weakness I'd displayed had at least soaked the swollen target; resuming the flagellation I knew the wet flesh would sting even more and the crack of the leather tails as they made contact confirmed this. My slave sister was fully surrendered to her sub-state of mind by this point and the sharp contract between my mouth's embrace of her tender tits and that of the flogger produced a dreamy smile of ecstasy across her angelic face that increased my resolve to make the events of the evening memorable in the depth of their depravity. Our Natural Selection Ch. 02 I stood back to admire my handiwork, or in this case my mouthiwork. The glazed look of demented rapture in my sister's blue eyes was a delight; obviously alternating the torture of her lactating breasts between using my teeth and my flogger was driving her into the stinging sensory overload that she was increasingly addicted to. Although initially unplanned, or rather unconcerned about the chance of it happening, the impregnation of my teenage sibling was now paying dividends in debauchery that I could never have dreamed of. She stood slightly swaying but keeping a respectful posture before me... naked and slender apart from the sexy roundness of her full belly and the reddened roundness of her tormented tits, marked most adorably by the welts of the flail and the love bites I'd just presented upon them as I tested the taste of mixing the dripping mother's milk with the heady liquids I'd smeared upon them scooped from her freely flowing cunt. Impending motherhood certainly had my enslaved slut of a sister blooming... the harsh treatment I'd inflicted so far and the fact her hands were tied behind her back had her perfectly formed chest thrust out as if begging for further attention; her heavy breathing adding to their distress in a manner that had fierce lust rising up inside me. Pure white mother's milk was still escaping slightly from her rock hard nipples, a reaction from the flagellation or my determined suckling maybe; whichever it was it was a beautiful sight to behold and I had the overwhelming desire to use her ripe, productive breasts for further defilement. Grabbing my angelic slut of a sister again by the red mane of hair I pulled her rudely towards her childhood bed, a sturdy 4 poster, and since her bound hands made her powerless to resist even if she'd wanted to it took the merest of pulling to off balance my slave so she landed softly upon her mattress, her hands still tied behind her back and trapped underneath her as I maneuvered her square on her bed, the slim body I'd pinned down there so often in the past looking unusual with the full stomach normally so flat sticking up out of place. However my sub slut's delicate situation didn't make me hesitate my grabbing of each shapely ankle in turn and securing it firmly to the adjacent bed post so her legs were bound splayed wide, fully exposing her tantalizing oozing cunt in a way that I knew made her fully feel like the whore she had become for me. I drank in this glorious sight stood at the base of the bed, my lecherous gaze going from her glistening spread thighs to the swell of her baby filled belly and up to her pretty face peering expectantly over the tummy lump, her clear blue eyes shining with excitement and anticipation.... since we'd embarked on this amorous and amoral adventure all those months ago she'd increasing become addicted to taboo treatment and whilst pregnancy had increased her appetite for her Master's cock wherever I saw fit to insert it in her the opportunities for this prolonged gratification had been scarce of late and I intended to tease my insatiable sibling and give her a fucking that she'd remember. Therefore I made myself not plunge my aching erection deep into her gloriously enticing vagina and instead dipped my head between her lean and lovely legs and ran my tongue up the sensitive flesh of her inner thigh and dipped my face into the oasis of her delicious cunt, my tongue forcing itself inside her tight hole and being rewarded by feeling her entire body shudder helplessly beneath my wet enclosed face as I drove my tongue wildly following the stream to flick against her girl-lube flavoured puckered anus then slowly back up to trace the folds of her engorged labia and seek out her hard nub of smooth clitoris and draw on it gently with my teeth whilst maintaining the swirling of my tongue against that most receptive of buds. I kept up the oral pressure until my teenage fuck toy was squirming against me in a most gratifying way, trying to thrust her bald pubic mound against my face with abandoned passion; I took a last lap into her liquid reserves then crawled up her body maintaining my soaked lips and tongue against her searing flesh, slowly up the rise of her occupied stomach licking and spreading her own wet wanton excesses across her taut skin. I hesitated when I felt the indent of her belly button under my lips, teased it wetly, then continued up the rise of her tummy until I'd reached its uppermost peak where I allowed myself the magnificent view down the other side of the slope. My prized breeding slut was gazing up at me with sheer perverse joy covering her sweet face and painful looking welts covering her leaking tits and now they had grown in size to provide maternal nursing services it was time to use them to serve my depraved lust. I moved from between my squirming sibling's parted legs and kneeling on the bed roughly raised her by her shoulders into a high enough position so I could fumble underneath her body and release the slipknot binding her wrists together.....I'd hate for them to become cramped and numb just when I had use of them. Once freed, I shoved her back into the laid on her back position, still at my mercy with her ankles secured tightly and spread wide. My possessed pet had a slightly quizzical look upon her beautiful face but she trusted her big brother enough not to seem too concerned.... even when I threw my leg over the petite part of her upper body and knelt looking down at her, my heavy manhood a solid shaft between my view of her wet breasts and sweat glistening face. I carefully lowered myself down onto her still skinny rib cage and pinned her down completely, enjoying the sensation of her tummy bulge rubbing against my buttocks as I took my staining and bobbing erection in hand and angled it down enough to make contact with the tormented tit flesh, radiating heat delightfully against the sensitive purple bulb of my insanely aroused cock. "I'm in the mood to fuck your breasts now I've made then receptive to the task with the flogger," I casually declared to my lusciously lactating slave as I gripped her wrists and positioned her tiny hands upon the tantalizingly tactile treasures that were her tortured tits. All thoughts of alliteration use were nearly blotted out of my mind as my natural slut of a sister mashed her maternally enlarged mammary glands together to envelope my grateful prick, the protruding teats secreting milky goodness in the process as if trying to match the lubricant producing properties of her always moist cunt. I groaned in appreciation of the sensation and instinctively thrust my pelvis forward... I'd been aching to put my erection to its natural use all day and the perverse soft haven of my sex slave's cleavage was irresistible after the painfully arousing treatment I'd treated her to recently... especially as I was defiling the purity of motherhood with every lewd motion of my groin, the tempo of my stabbing cock increasing as animal lust surged up in me, the excitement added to by the depraved look of bliss on my licentious sister's face at being used in this manner as she managed to keep my pounding cock enveloped between her punished breasts whilst also pinching and manipulating her engorged nipples so that as a rhythm was achieved her attentive actions stimulated twin jets of warm dairy richness spurting up against my hairy belly and chest as a perverted premonition of the effect that this tit-fucking was bound to have upon my quivering cock. Much as I was seized with the desire to lose all self control and add my hot cum to the creamy concoction being created on my sister's chest I resisted the urge... from the frantic tugging on her nipples that my sister was indulging in I knew she was desperate for the hard fucking that all this innocent foreplay had been leading up to and intoxicating as the sensation of abusing her in this manner was I wouldn't deserve to Own her body and mind if I gave into every selfish compulsion to cum over her, much as my libido was screaming at me to give in the animal lust surging up from this latest piece of depravity we were sharing with gleeful abandon. My pelvic thrusts were getting harder into her increasingly slippery cleavage and with a little more momentum I lifted my body higher and slid up her, straddling her wet breasts enough to force the tip of my cock past her up tilted chin and hard against her mouth....the passion of the moment had ensured that my slaves mouth was already hanging slightly loose and she instinctively widened it to accept the intruding purple cock meat, her lips greedily closing round its bulging rim as her tongue darted across its taut smoothness with well practiced skill seeking out the most sensitive areas and sending fresh waves of electric shocks of pure pleasure shooting throughout my entire body. I was still jerking my hips in the same frantic piston motion that I'd been enjoying as I fucked her tits and my accommodating slave bravely took it, but I wasn't so lost to lust to not realize that my impromptu positioning was a heavy burden for her abused breasts. I swung myself off her chest whilst ensuring that my orally lavished erection remained snugly inside my sister's pretty mouth and kneeling by her head I took grip on that most convenient of hand holds and used her hair to pull her mouth into the best angle for some forced fellatio. The wild lust surging up in me was matched by the sense of Domination and power I had over my precious sibling... to take her like this, impregnated, and sexually defile her to the extent I had this evening was an indescribable feeling... and then to look down and watch her devour my pounding cock with such devotion...life was good. It was a further source of gratification to see than my unrepentant nymphomaniac sub was so lost to the intensity of the occasion that she had brazenly snaked an arm down and round the full swell of her belly to reach out to stroke her fat little clitoris whilst the other hand still milked herself, roughly moving from nipple to nipple and releasing the pent up cream as her orgasm obviously approached. This vision of inappropriate motherhood behaviour had me forcing my solid shaft hard against the back of her throat in approval... a move that did nothing to dampen her desperate actions, but I drew back from the blink of total loss of self control, much as I wanted to erupt hard into her mouth and trigger her own orgasm. But my baby sister deserved only one way of being made to cum for her Master; the same way she'd been placed in her current delicate situation, a semi-permanent hormonal state of frenzied arousal that had pushed her voracious appetites to new levels.. I threw myself backwards, wrenching my erection from the perfect seal of her soft lips with an obscene pop and slid off the bed, eliciting a frustrated whimper from my human pet. Keeping my feverish mind fixed upon the final prize I hurried to the foot of the bed and released the slipknots binding my sibling's trim ankles to the posts with lustful haste. "Present yourself, slave," I growled in a guttural tone that reflected my concupiscent mood and despite her sexually dazed condition she had been trained well enough to react without the need to think... with some slight difficulty due to her full belly she raised herself and turned over so she was in the required kneeling position, bent forward holding her body horizontal with a firm grip on the bed's headboard and ready for convenient mounting. I hesitated for a moment to admire the breathtaking sight of my compliant slave awaiting her reward, her pert round buttocks and firm thighs a beautiful frame for her puffy engorged cunt, leaking a steady stream of clear viscous fuck fluid expectantly and alongside the burning desire I felt a sense of accomplishment. I had taken my sweet sibling and transformed her into this panting, pregnant pain whore before me and in enslaving her given her the freedom to give herself to the sexual sordidness that such a deserving licentious girl could only ever be truly happy wallowing in. "You are mine," I whispered as my hands gripped her hips and my impatient erection buried itself in the slippery groove of her bald cunt and skated along its wet folds until I felt its slightly gaping ingress positioned around the tip of my intruding prick. I had to take her then and with firm determination I sank my granite-hard shaft into her ripe tightness in one thrust, lubricated as she was it was still a marvelous resistance as I penetrated her as deep as I could and the mind blowing sensations breaking over me where enhanced by the fact that my slut of a slave started to cum as soon as I entered her and forced myself down to the hilt. Single orgasms were no longer an option for my insatiable nymph tho' and I took her back-arching orgasm as a request to be fucked harder... a request I intended to fulfill. Drawing back, I began to pound her silky cunt with animal abandon, my thighs slapping against her buttocks as I rammed myself harder and deeper with every piston-like thrust. The chain reaction of orgasms exploding through my sister's frame was impressive and she was lost to her normal submissive nature in the throes of such violent, rapturous exhilaration. "I love you, Master," she yelled. "Fuck me hard and make me your whore, please never stop.... use me forever and keep making me cum so nasty like the disgusting slut I am... Oh, Sir... fill my womb again...fuck me fuck me fuck me—" She was getting incoherent as climax after climax rocked her petite frame and I took firmer hold on her convulsing thighs in case her state of delirious disconnect made her forget her delicate position and collapse flat on her swollen stomach, although her knuckles were showing white as she held on to the headboard as if her life depended upon it. My own orgasm was fast approaching as her spasming velvet cunt gripped my faster pounding erection and her pleas of unabated ecstasy rang in my ears...I wanted to shoot my hot and heavy load against her cervix as a final spur to the string of orgasms that were making her jerk uncontrollably beneath me, and as sometimes happens in these moments a quiet little though popped into my head amongst all the white hot single minded thoughts of lust. 'I wonder if my slave will still be this tight after the birth?' I mused abstractly and the answer I gave myself finally pushed me to the point of no return.... a looser cunt would give me the opportunity to begin fisting training. This delightful prospect and a final deep impaling thrust had my senses swimming with the electric bliss of release... I erupted deep into my already defiled slave's body and kept my unwholesome fucking going as load after incestuous load filled her... as expected, this pushed my delicious slut beyond the realms of pleasure tolerance and she went limp as ecstasy engulfed her rationality altogether. Still grinding my cock into her clutching cunt I held her hips tightly as she collapsed her head down into the pillows in final surrender, her impregnated stomach nevertheless protected in that bowing position. My jerking cock finally discharged the last of its seed and I knelt with our loins still fused together whilst I recovered whatever composure I could. My sister was muttering nonsense words of gratitude and servitude into the pillow as I gently withdrew my still erect cock from her body and rolled her onto her back just to be safe Her face was glowing with sexual serenity although she appeared to have passed out. Slightly concerned, I bent to examine her and sensing my proximity her blue eyes slowly opened and she gave me a brilliant smile of pure bliss before remembering her duties and opening her mouth happily to accept my slightly drooping cock which she lapped clean with contented dedication, her tongue relishing the final seeping of sperm that had originally placed her in this maternal condition that we were abusing so perversely. Our Natural Selection Ch. 03 I allowed my slave girl to finish showing her greedy devotion in the way she relished most, licking the erection that had just fucked her into the state of delirious and defiled bliss that she constantly craved even more desperately since I'd impregnated her all those months ago. Her talented tongue savoured the mix of our combined sexual secretions and I felt the blood returning to my cock as she increased the enthusiastic oral attentions in the way she knew drove me to renewed passion.... not that it took much to move me to that happy state. My sister is a stunning red-headed eighteen year old beauty whose blue eyed innocence could tempt the... I'm racking my brains to think of the most unlikely person to use as an example, the fact I can't think of a single person to fit the bill should give you a clue to her attractiveness. The fact that the contents of her brain are as debauched as the contents of her clothing, when she's wearing any, just adds to the joy of Owning her. I sometimes think how lucky she is to have a brother as considerate as myself... what a waste it would have been if she'd been an only child and that appetite for vice in all its more extreme forms had gone unexplored. A swell of possessiveness flowed over me and I roughly pulled her face from my wet sticky groin and tilted her head up so I could bend low enough to kiss her soft lips, still tasting our salty sweetness on her mouth as we kissed lazily and long--a shared intimacy that the young mother-to-be deserved for being such an abandoned pain whore. Still kissing we slid into a comfortable side-by-side reclining position for a much needed rest after such a frenzied bout of unwholesome fuck action; my sister's slender frame, apart from protruding belly, eased itself against mine so when our mouths finally parted she could rest her tangled mop of fiery red curls on my chest and stare up respectfully at her Master with that look of sated contentment on her angelic face that makes all my exertions worthwhile. I stroked her hair idly like the pet she was and we lay peacefully for a while, recovering our strength and gently exploring each others' bodies with trailing fingers... not lustfully, yet, but just as displays of familiarity. I had no intention of allowing this break in her training to last long: The opportunities for full on depravity were not so common whilst we both were living under our parents' roof and, besides, in her current delicate condition I knew that my wanton fuck puppet's hormones were keeping her in a near constant state of arousal that was pushing her to nymphomaniac excesses that as her big brother I naturally encouraged. Even in the aftermath of the punishments and pleasures I'd inflicted upon her I knew she was ready to be forced into fresh defilement, not least because her hand had found its way between my legs and was doing that strange fluttering caress she'd mastered upon my testicles, alternating with stroking lightly the length of my heavy shaft in a way that saw it responding in the only way it knew how. I noticed at this point that my molestation of my little sister had grown firmer in unconscious unity... the available breast standing clear of my body I had in the palm of my hand and was kneading in the way I knew would get results. Sure enough when I pinched the nipple I was rewarded with a thin white stream of milk and a gasp from my deliberately prematurely lactating sub. It would have been a shame not to have taken full advantage of this expression of her perversion after all those laborious hours using the suction pump on those perfect and perky alabaster tits... a painful process that had my slutty sister masturbating ecstatically as I operated it. I milked her already recharged breast with growing harshness and my pain whore mother-to-be scrambled up to give me access to her other teat which I grasped happy to perform the service. The only noise in the still of my kid sister's bedroom was her groans of appreciation as I pulled upon her swelling cleavage, still covered with crimson streaks from the earlier flogging I'd treated them to. Silently I maneuvered her until she was straddled across my laid flat body... sat astride her Master erect and proud as I reached up and manipulated her fat nipples, sending spurts of warm dairy goodness flying free and down upon my already sticky body and face. The temperature of the evening was rising again as my lithe little slut arched her back under the influence of this lewd abuse of her nursing apparatus, pushing her full curve of her impregnated belly forward and as she squirmed her smooth outspread thighs against my horizontal body I felt further wetness spreading on to my skin from between her legs, a mix of her ever-flowing fuck juices and the seeping of my cum expelled unneeded from her already fertilized womb. This damp reminder of our recent fornication reminded me that the straddling position I'd placed my sister into was one of the approved positions for pregnant intercourse and interesting sensation as it was to have her internal fluids leaking onto my midriff, I could think of a more receptive part of my anatomy... the one returned to full solid erectness and straining to be included in the filthy fun. "Slide down, slave, get that wet cunt sat on my cock," I advised and with both my hands maintaining their maternal massage she edged down my body until her slim hips were spread across my thighs and without ceremony she was able to grind the hot and slippery folds of her labia into the hard contours of my erection, imprisoned between our gyrating bodies. In this delightful position a rhythm was soon established, her riding the ridged length of my soaking cock from tip back down to squash my balls as I emptied her tortured breasts of their nourishing content. The tempo of my sister's pelvic thrusts against my hardness was increasing as I recognized her ragged breathing and glazed look on concentration on her pretty young face as the approach of another orgasm... her breasts must have been sorer than I thought.... and though I knew my recovery time for climax was much longer than hers it seemed to be a waste of a good erection unless I had it lodged deep inside my fuck puppet to help her sexual release. Releasing the tantalizing handhold on her leaking tits I reached round under the fullness of her occupied belly and sunk my fingers into the pliant firmness of her tight buttocks, pulling them apart and pushing her down a bit harder against my lubricated cock. "If you want to cum again then you've got to have me inside that precious little arse of yours," I told her kindly. "It's yours, Sir, to use as you like," she replied quite correctly and since she'd been working herself up into a nice little frenzy she took the initiative, lifting herself up off my prick and leaning forward enough so that it bobbed up free and whilst I held her arse cheeks splayed she brazenly took the straining cock in hand and guided it carefully to that puckered cuteness at her rear that I'd enjoyed so often in the past. I was seeing this obedient compliance from an unusual angle, looking up into the familiar face of my little sister, a look of seriousness mixed with lust spread across her visage as I felt the tip of my prick make contact with her sphincter. Bloated as it was it was also well lubricated with the liquid outpourings of her own loins and she screwed her face up as the cock-head pushed relentlessly against the anal seal. Something had to give and it would be her anus... I felt my sensitive flesh enter her anal ingress slowly until it stretched her cruelly... I laid back with hands still holding her cheeks apart letting her set her own pace for the sodomy, but once she'd inserted the whole of my glans inside herself her passion and impatience overcame caution and she thrust her back down onto me, impaling herself down to the hilt with a shriek of emotion. Such a slutty dedication to her Master warranted suitable tribute, so I gave her buttocks a quick slap and withdrew my hands... I ran my fingertips to the rigidness of her fat clitoris eliciting a shiver of pleasure that I shared with her through the effect it had on my cock buried unnaturally inside her, then ran my hands across the curve of her oval belly, dripping with expelled breast milk before returning to her much abused tits and resuming their milking. My slave gave a groan of husky approval at my hands' return and threw her lovely head back as a fresh duel arc of cream was forcibly expelled from her sore nipples. "That's more comfortable, isn't it?" I cooed and pushed my hips up to remind her that her ass was full of her Masters invading cock. "Yes, Sir, thank you," she murmured, wincing since I accompanied the thrust with a double pinch to her tormented teats that shot white liquid away over my head. "Good, now prove to me once again that you are my whore... make yourself cum and let me enjoy the feeling of it on my cock lodged so sweetly inside your arse." My insatiable, incestuous slave didn't need any prompting; I'd trained her to let her fingers stray to her own cunt without any shyness and being buggered and milked at the same time in this manner was a vice that my pain whore hadn't experienced to date and she relished giving herself fully to all new perversion. She looked a portrait of debauched perfection as her slim fingers sought out her swollen pink pearl and began frigging it... leaning forward as I supported her body with the grasp I maintained upon her wet tits. I held her in this infinitely incestuous position and luxuriated in the sheer wrongness of making my baby sister anally penetrate herself like this to enhance her masturbation... still, judging by the way she was shifting her weight to make my steel erection delve further into her body, this crude sodomy was having the required effect. I continued to massage her reddened breasts, marveling at the continuing spurts of cream that I could coax out of her as she pushed her chest against my cupping hands and pushed her cute arse against the full cock holding her pinned to my thighs. My little slave's tits had grown at least a couple of cup sizes since embarking upon artificial acceleration of the lactation process with the same single minded enthusiasm that had been the hallmark of her sexual submission to me and whilst they were not over-sized now they were noticeably larger... cute little tits that my hands covered so perfectly now overflowed as I brutally manipulated them. On sudden impulse I mashed them together in the same way my slut had held them earlier in order for her beloved brother to sink his straining prick between them and fuck the milk-lubricated cleavage to such delicious effect. Pushing her tits together I made sure that the nipples and aureoles made contact and were rubbing together... her teats were swollen and sore looking from all the extra attention they'd received and they looked so irresistible, so hard and erect dribbling white still that I leaned my head up enough to capture them both in my mouth and drew my teeth sharply along their jutting length, eliciting a fresh double burst of mother-to-be's milk into my mouth and a yelp of ecstatic surprise from my slave sister. I maintained my dental grip upon the dual juicy knots and bite and chewed upon the tender paps, the effort of holding my head to them added to most delightfully by the way my unrepentant pain whore was now bouncing her firm buttocks up and down my hips and forcing my appreciative shaft to fuck her tight anal tract, stretching her sphincter to new limits as my cock grew even fuller and harder as it pummeled up and into her at the tempo she was dictating. As I got swept up in the increasing lust I wanted to cum inside her again and fill her arse with cum the same way I'd recently filled her fertile and fertilized womb, but this wasn't some corny story and I knew that my next orgasm would be a little while off yet... still, that was no reason why I couldn't wallow in the electric sensations being transmitted down my impaling cock, or indeed enjoy the effect it was having upon my beautiful sibling who was beyond all restraint by this point and was thrusting herself backwards upon my raw erection with the single minded passion that the triple hard stimulation of her pleasure centers was driving her into. The enthusiasm of her bucking actions was making her take longer and longer slides along my shaft and I could tell from her sobbing and panting that she was on the verge of climax... the rhythm of her fingers' motion upon her aching clitoris matched the abandonment of her throwing herself upon my erection and her full belly was being pressed against mine without regard for its contents so I released her chewed nipples and pushed her upright so I could take control of her orgasm. My little slut whimpered as her breasts swung free but I quickly caught hold of them again since they were such responsive hand holds and, with her sweat sheened body held at a more responsible angle, I began to thrust my hips upward to meet her bobbing arse cheeks until we had achieved a crazed tempo, her body acting desperately on auto-pilot riding my pistoning shaft oblivious to everything apart from the sensory deluge she was losing herself to. Her split wide cunt was flooding juices down onto my belly and balls most wonderfully and once again the pinching of her fat nipples was spraying warm cream down across my face and hair as her anal passage was ravaged mercilessly by a combination of our exertions....finally her back arched gracefully as she landed especially hard on my invading shaft and she let out a howl of pure mindless pleasure... I felt her anal ring clamp and clutch the base of my cock as her entire body jerked spasmodically and she ground herself down onto my impaling prick in a way that made it swell even more. feeling her cum this way buried so deep inside her was thrilling and I wished I was ready to shoot my next load so I could add just a further act of depravity to her evening's indulgences... I knew having my hot baby-making spunk exploding inside her arse would appeal to us both, especially if I made her clench her buttocks and hold it internally until I allowed her to let it trickle free like I had in the past. However, exciting as it was to have her sat so solidly on my cock whilst another orgasm filled her entire world, I concentrated in holding her aloft and safe until a slow satisfied smile filled her fresh face and she looked down at her milk splattered brother with that delightful look of adoration and devotion that made my cock lurch as much as my heart. I held her in that compromised and sodomized sitting position a little longer admiring the view looming above me, then I urged her to raise herself slowly so I could enjoy the tight heat of her arse as my cock was withdrawn out of her, and finally it emerged springing up into cool air... fully erect and ready to fuck. My enslaved slut gave a contented little sigh, basking obviously in the rearing effect her rear had had upon her Master and I guided her down to lay once again by my side so she could recover and we could let our mouths meet in the passionate kissing that was always the perfect aftermath of such intense sexual debauchery. Our tongues fluttered madly against each others' and I felt her melt against me as the total relaxation of post coital bliss flowed over her. I let her rest a while... it would only be a little while I knew, my arousal was growing again and valuable time was passing... my hot little impregnated slave was going to be worked hard this night and in her delicate condition she need to regather her strength. I stroked her hair and taut body and presently I knew she'd drifted off into a light sleep. Carefully, I disengaged myself without waking her and slipped out to take a shower... I was sticky and coated with various drying fluids that my clever possession had exuded— a refreshing shower would sharpen me up and prepare me for the next chapter in my sister's on-going training in unrestricted vice and depraved servitude. Our Natural Selection Ch. 04 I stood under the shower's restorative deluge and quickly lathered myself clean of the various bodily fluids that the latest bout of sisterly defilement had seen me covered in... Not that I minded much, but a certain Dominant standard had to be maintained and it was best if only my slut slave remained in such an excitingly sticky and thoroughly fucked state. The water felt good pounding hard against my chest and upward straining erection, but the memory of my wanton sibling's burning ass clamped tight around my impaling cock as she straddled my hips and sodomized herself enthusiastically was still fresh in my mind and I was eager to proceed with the evening's incestuous diversions whilst our parents were out of the house. Therefore the briefest of showers was all I could tolerate and I was barely toweled dryish before my mind was swirling with perverse plans and impelling me to return to her bedroom and the sprawled slender figure slumbering lightly in her childhood four poster bed. As always the wondrous sight of my slave-sister reclining in all her naked glory forced me to hesitate and linger over the vision admiringly. I was still getting used to the alien contrast between her normal lithe sleekness and the protruding roundness of her bulging belly and swollen tits but impregnating her had taken my Domination of her to an intense new level that was intoxicating.... There for the world to see was proof that she was my possession, my Owned fuck pet who was only truly content when she was serving her Master or being served the physical punishment she relished so fiercely. As I watched her she stirred and smiled up at me with a look of sheer bliss... I should have known better than to think she'd allow herself to drift off to sleep in the tiny space of time I'd left her alone; I'd promised harsher treatment and already she was anticipating the form it would take. Pregnancy had made her insatiable for every attention I lavished upon her pale, tight young body. Catching hold of the collar round her neck I raised her to a sitting position gently and tilted her face up for the meeting of our lips that I could never get enough of, then dragged her to her feet off the soaked and stained bed. "Don't forget to change these sheets later," I instructed although I knew that our parents would be returning late and discovery of evidence of our incestuously illicit activities was unlikely. Which reminded me, it was time to lead my glutton-for-punishment slave down to the basement now she'd had her warm up chastisements... My fertile little fuck puppet was long overdue the firm work out that the den below could deliver. It had been intended as a family leisure room in our youth but never really developed as such and was abandoned due to lack of interest. However, since taking my sweet sister as my personal pain whore I had found lots of inventive uses for its sturdy overhead beams and supporting pillars along with the discarded furniture that had found its way down there over the years. I'd claimed it as our secret play room and we sneaked down there as much as was possible without attracting suspicion.... Tonight, however, we had hours left to test my slave slut's various thresholds and with that delectable thought in mind I retrieved the hold on my perverse pet's leash and pulled her by the collar towards her bedroom door. There was always something extra intense in the mood when the opportunity of an empty house arose; to be able to parade my slave through familiar surroundings naked and proud in her sexual submission to me and in her current condition.... belly swollen, tits glowing with their caresses from the flogger and still slightly leaking milk in gratitude that made the occasion even more special. It would have been unseemly to rush her down the stairs, certainly her deliberate and graceful walk was poetry in motion, but I was impatient to get my hands back upon that perfect body and get my cock back inside her. I let her take the lead so I could admire the roll of that intoxicating arse, still striped by the red welts of its initial warming up and it was due to this eye catching sight and the single mindedness of my anticipation of further Dominating debauchery that my attention was elsewhere. We reached the foot of the stairs and turned into the hallway that would take us to the basement door when I was snapped back to reality by the abrupt halt of my naked sister, so unexpected that I walked into her suddenly motionless body and nearly dropped the collection of implements of torment and lengths of ropes that were vital for the intended continuation of the evening's deviant play. Before I could utter a comment on my slave's almost disobedient halt I saw the reason for it: There was a figure stood down the hallway just inside the back door in a posture of shock similar to the one my sister and I were frozen in... Whilst we had the advantage of being residents of the house the intruder had the edge as she was fully clothed and not presenting such a vivid portrait of incestuous perversity as I'm sure we displayed caught in such a compromising position. I instantly recognized the woman stood mere feet before us, although the look of wide-eyed, open mouthed amazement upon her face wasn't her usual expression.... it was old Mrs. Parker, "Nosy Parker" as we'd always called her, our next door neighbour and almost the last person on earth who I'd want to be discovered stark naked leading my equally naked younger sister around on a collar. As a rebellious teenager with a habit for getting into various scrapes my relationship with Mrs. Parker had been understandably frosty... She was a self-righteous, church going pillar of the community who didn't enjoy my hooligan antics and had made it her mission to monitor my comings and goings with a combination of curtain twitching and disapproving sermons about "the youth of today" and its lack of morality. I couldn't help thinking that this catching of us in such a blatant exhibition of all her warnings to our mother about how I was a bad influence upon my innocent sister would provide her with a lifetime's supply of smug justification of her one-woman neighbourhood watch campaign against me... and yet as we stood in a silent stunned face off I had to notice that she seemed to be somewhat mesmerized by the taboo tableau that she'd wandered into. In fact, instead of the expected hysterical denouncement and screams for the police, fire brigade and a priest with full exorcism kit that I expected to issue forth, when she recovered her voice she remained silent and rooted to the spot, as did we, not so much through embarrassment as a total loss at what could be actually said to explain the awkward situation we all found ourselves enmeshed in. "I thought I heard someone shouting for help." It was Mrs. Parker who finally stammered words to fill the silent void holding us all in limbo and it did seem a viable statement considering my slave had just recently been cumming at the top of her lungs for her Master... Who'd have thought the dividing walls were so thin. Mind you "Nosy" Parker never needed much of an excuse to snoop and I'm sure her moralistic indignation had been going into overdrive recently upon learning of the scandal of my 18 year old sister's pregnancy. Any chance to mix neighbourly concern with sticking her beak in must have been a Godsend for her... and she was a God botherer of the first degree. Before any kind of intelligent answer could be thought up on my part she uttered her second statement of truth "You both haven't any clothes on," she whispered in wonder as if witnessing some divine appearance and she'd never spoken a truer word. I wondered if she was so innocent in the wicked ways of the world that she thought there was a viable explanation for our nakedness, and if she did what the fuck could it be so I could use it. Luckily, I was mostly shielded by my sister's body and Mrs. Parker couldn't see my erection bobbing not-so innocently against my sister's spine where it had positioned itself since I walked into her. Events had happened so swiftly that I hadn't even thought of covering my swollen shame; in fact I noticed that my sister didn't seem to have considered any moves towards modesty herself, her hands were holding the underside of her full belly supportively but under the circumstances she seemed pretty bold as she stood proudly before the annoying neighbour... ... that same annoying neighbour who upon closer examination was still presenting a fine impression of stunned indecision with mouth gaping at the bare fleshed apparition she'd intruded upon. Still, as long as she wasn't screaming the place down, it gave me time to think and try to work out how to solve this rather difficult situation. I couldn't help observing that given the obvious sinfulness of the discovery Mrs. Parker was being somewhat meek; surely she must have understood the full implications of what she'd walked in on, a line of thought that made me suddenly question the innocence of her snooping. My sister's orgasmic cries had probably been clear enough so why would our neighbour be so brazen as to come a-prowling unless......... I was shamed of myself; I'd underestimated my sexy sister's seemingly unlimited powers of perverse appeal, although old Mrs. Parker was as an unlikely candidate as I could imagine, and yet reexamining her in this new light it explained the current wide-eyed gaze upon my slave's obviously ravished and about to be ravished form. Who'd have thought the old busy body would have such taboo good taste, although having said that I had to reappraise our Devil dodger from next door. Her body was suddenly worth a second glance now her amble bosom was in a state of increasing agitation and without the usual look of disdain covering her face she looked more like the 40-ish woman she was...her dark features vastly improved with the potential for depravity beginning to show through and I couldn't think of a better way of ensuring her complicity than implicating her fully. All we had to do now was nudge her in the right direction and encourage her to break down years of repressed lust... the internal struggle was raging inside her and still could go either way. Luckily, my exceptional sister was as much a natural seductress as she was a natural sub slave slut and I could sense she was way ahead in me in her appraisal of the confrontation. Despite the fullness of her swollen occupied belly she'd straightened her spine and held her shoulders back in a provocative posture that her exhibitionist instincts knew made an intoxicating sight, her full round little tits thrust up high and proud in a display that few could resist, especially when combined with that angelic expression on her pretty face that was an open invitation for debauchery. Still the moment could have gone either way had my clever concubine not been fully aroused and shameless... she'd been promised a trip to the basement by her beloved Master and nothing would be allowed to delay proceedings much longer. Preening herself in the full attention she was demanding, my slut sister slowly and deliberately began to run her hands upwards over her burning flesh until she was cupping both reddened breasts and began to concentrate her fingertips working her achingly erect nipples until the fresh drops of white cream began to appear. My dear sister's sexual instincts proved as accurate as always. Mrs. Parker gave a little moan that ended all pretense and her eyes were wild with the fire of lust burning in them... That new look on her face and the fact that somehow the ensuing deep breathing seemed to have loosened Mrs. Parker's respectable blouse which was now showing a disreputable amount of cleavage was forcing me to rethink my opinion of our tempted neighbour... It was time to push her over the edge and let her embrace all her new found dark desires. I pulled my slave's leash slightly to get her attention and to make it obvious who was in charge should the detail and scope of Parker's discovery have gone unnoticed in the confusion. "This girl you know as my sister is now my sub, my enthusiastic slave and slut. I Own her and use her as my sexual toy whenever possible... she is mine and you've interrupted tonight's training and punishment session. You've got a choice now Mrs. Parker, you can leave or you can follow us downstairs and find out what an unrepentant pain whore I've turned my sweet innocent sister into." I felt it was a pretty safe bet as I'd launched into my speech and noting the radiant smile my slave gave our shocked neighbour I took the lead and led my sister by her collar and chain past Parker, now looking strangely voluptuous once her voracious appetite had been wakened. Carefully I steered my naked slave, still pulling on her nipples with undisguised relish at this unexpected chance of showing off her submissive dedication to defilement before an audience, down the narrow steps that took us to the basement at last and with the last vestiges of morality cast side we were followed by the good Mrs. Parker. Our Natural Selection Ch. 05 My slave sister's naked feet made a soft padding noise on the wooden stairs that led down to the basement as I led her by her collar and leash and I savoured the harder echo of high heels ringing in reply that told me without having to turn round that we were being followed by down to the play room by our over inquisitive next door neighbour Mrs. Parker... Being a long standing and church going pillar of the community hadn't protected her from real temptation from sin when that sin had confronted her in the divine shape of my pregnant and perverse teenage sister. At the head of this descending parade I pondered the implications of this unusual turn of events and felt my ego swell along with my erection. "Nosy" Parker and her one women neighbourhood watch surveillance had long been a pain in the arse what with her constant holier-than-thou attitude and general right-wing crusading; now it would seem that like most people who are keen to impose their morality on everyone they can a certain amount of hypocrisy was involved. I was looking forward to encouraging her to debase herself as she succumbed to the pleasures of the flesh, especially since the flesh I intended her to prostrate and prostitute herself to would be my gorgeous slut sub who reveled in deviant behaviour as much as her Dominating brother. I'd reached the foot of the staircase by this point as had my impregnated possession and I took the opportunity to turn and give her and the ensnared woman still halfway down the stairs an appraising glance. She froze as my sister and I looked up at her, a guilty look hovering across her face as she wrestled with herself still, perhaps realizing that once she'd descended to our level she would be lost beyond all redemption... It was in our best interest to recruit this older woman in order to ensure our incestuous relationship remained unpublicized, so I drew my precious pain whore close to me roughly and standing behind her placed my hands over her own, still massaging her productive tits and just beginning to restart the lactation in dribbles of warm milk escaping from her rigid nipples, still raw and receptive from the harsh treatment they'd enjoyed earlier in the evening. My supple slut murmured appreciatively at this added attention to her aching breasts and pushed her lower body back against me to make contact with my rock solid cock as a gesture of gratitude and servile lust. "I'll milk you now, you show Mrs. Parker what a hot little whore you are," I instructed still looking over her slim shoulder up at our erstwhile upstanding citizen from next door. "Thank you, Sir," she purred, slipping her hands from under mine and, her natural sexual exhibitionism taking over, placing her fingers to her mouth to lap the cream from them before running her hands slowing down her succulent slender body, rubbing the splashes of milk that had landed on her swollen belly sensually over her taut curve then reaching down to her hairless public mound to stroke her sticky wet cunt, drawing the girlie fuck lube up her trim labia to find the jutting pearl that was her attention seeking clitoris. She sighed and lent back against my supporting body so she could display her masturbatory performance to the older woman looking down entranced from the stairs. I pinched her protruding nipples as she teased her fat clit and observed that she was staring up into Mrs. Parker's eyes with unmistakable invitation... Showing off her submissive obedience before such an attentive audience had my sister slipping back into insatiable desire again and it was certainly helping resolve any hesitation on the part of our nosy neighbour, who'd actually descended a couple of steps without conscious thought before she realized how strong the lure was and she'd paused once more without taking her eyes from the stunning sight drawing her so inevitably into depravity and disgrace. This further disintegration of Madame Purity's self-control had me working my sister's poor tits even more urgently and twin spurts of mother's milk shot forth in the direction of our guest... Mentally, I cursed that she was still maintaining a distance... I had the sudden need to see Mrs. Parker's sensible clothing and well coiffured appearance despoiled by bodily fluids of any kind, to crack that well-maintained outwards appearance of repressed respectability forever. Mind you, seeing her from this new point of view I had to admit she was looking more human... The eyes heavy-lidded with unspoken lust and the heaving bosom putting serious strain on her white blouse's buttons—even her responsible looking knee length skirt seemed to have tightened itself and ridden up her long legs somehow, reveling black tight covered shapely legs and strong yet feminine looking thighs that were not unbecoming on a woman whose air of being middle aged in the past lay more with her constant attitude of priggish disapproval rather than her actual age. She was about my height, 5' 11" or so, which put her a good few inches taller than my sister and her matronly curves made her a decided contrast to my siblings usual slim hipped, svelte perfection... I was eager to see my greedy slave take her into her arms and seduce her. This series of lewd developments had done nothing to cool my heightened level of lust and firmly manipulating my sisters ever-engrossing breasts reminded me of my original mission... Much as I was enjoying holding my slut sibling whilst she mesmerized our hesitant guest with her joyous exhibitionism it was time to reveal the full extent of my innocent sister's corruption and devotion to sexual depravity in its more extreme forms. The unique grip I had on my masturbating slut made her growing excitement easy to detect; she was never far from surrendering herself body and soul to pleasure at the best times but this evening had produced an overload of deviant thrills which she was still desperate to wallow in and my instruction to frig herself in front of a new, untested audience obviously held an appeal for my pretty little sensualist sub, but she'd have to earn her next orgasm. We were in the basement and punishment was the order of the day down here. Giving her red raw nipples a final pinch I disengaged my supporting clinch enough that she was forced to stand upright again, a signal that my well trained possession understood as instruction to prepare for a different indulgence. Dropping her hands to her hips away from her streaming cunt broke the intimate spell she'd been casting upon our upright visitor... Even tho' I'd been stood behind her I knew of old the devastating effect my slut slave's penetrating gaze had when she was giving into her basest desires and Mrs. Parker's eyes had been locked upon my slave's face. So as I tugged upon her collar and led her across the play room I was confident that our ensnared interloper would continue her descent into our playroom. Who could resist? The basement den was lit by a harsh strip light in the center of the rectangular room which added to the uncompromising nature of the space; a half hearted attempt to convert it into a family den by previous occupants years ago had not provided much in the way of comfort; the floor was tiled but the walls remained rough brickwork and the ceiling still exposed solid beams that we'd found an array of uses for in the past, from making rope swings on as children to more serious uses in the last few months since liberating my sweet sister and making her my compliant sex slave. The only objects in the room were an old sofa and a full size billiard table that had been wrestled down somehow and abandoned when the general gloom of the cellar discouraged further attempts at jollification. I guided my willing possession to the central spot where I'd previously screwed a heavy duty O ring into the wooden ceiling beam, a spot chosen so my captive's pale body was suitably illuminated by the glare of overhead fluorescent strip. Usually on these occasions I warmed her up with various lighter chastisements or spankings to push her into the right receptive state, but on this occasion I felt the addition of an unexpected observer coupled with the earlier indulgences had my precious little pain whore as ready to receive her punishments as she'd ever been. Standing in her familiar spot my sub instinctively stood straight with chin up as I unfastened her leash from its collar and set it aside. Not wanting to waste any time, I swiftly left her side and, setting down the flogger, crops and ropes on the scuffed green felt of the billiard table, I moved to one of the shadowy corners of the cellar where further instruments of our contact play were concealed behind forgotten storage boxes. Retrieving them I returned to my hedonistic sibling's side, noticing in the process that our obliging neighbour had found her way down the stairs and, although keeping her distance as much as she could, was pressed against the basement wall with a look of horrified fascination spread across her face. 'Well, if her imagination was expecting untold obscenities I mustn't disappoint,' I thought to myself as I crouched down to secure first one, then the other trim subslut ankle into the padded leather cuffs of the spreader bar which held my sister's legs nicely positioned apart at a comfortable and practical angle; as I was securing the second strap I stole a glance upwards at the smooth expanse of inner thigh and pouting puffy cunt lips exuding their leakage of fuck juices with her legs held parted... I regretted the spontaneous nature of the upcoming exhibition in punishment before our morally conflicted guest; had it been planned I'd have dressed my sister in her stockings and stilettos, she always looked so adorable dressed in such enhancing finery and the high heels added to her helplessness when secured in the spreader bar and strung from above. However my slave barefoot, naked and pregnant was such a stunning sight that it was a momentary passing regret instantly forgotten. With the same haste that I'd applied to her ankles I fastened the D ring bondage restraints around each wrist which she offered without being told, my sister's training and shameless eagerness for chastisement adding to her silent compliance. Nicely cuffed, I threaded the strong nylon rope through the rings and up through the hoop on the ceiling beam, then it was just a matter of pulling the rope taut enough to draw my sister's arms up and together straight above her head framing her angelic face, glowing with excited anticipation. I tugged it hard so she was lifted slightly off her feet and up onto tip toes then quickly tied it off to the solid dead weight of the billiard table leg. My pain whore looked truly helpless hanging there so exposed and swaying slightly in the unforgiving illumination of the strip light; I couldn't resist tugging her hair and pulling her face to mine to enjoy a passionate kiss, the forced hanging situation making our heights more equal and making the kiss all the more delicious. I ran my hands down her spine and cupped her pert buttocks firmly, pulling her to me as much as her expanded belly and my extended cock would allow.. .I loved holding her in such a grip knowing that she was secured so tightly and yet she felt so secure in my control... The trust between us was absolute and allowed my deviant darling sibling give herself totally to whatever bound situation I chose to indulge her with.... We'd never even discussed things like safe words or the like: I was her Master and she knew I'd never push her beyond any limit that she couldn't handle... The fact I'd never found a level of punishment that was beyond her limits yet was academic. It's strange how everyday tasks like securing my subslut sister hand and foot and hanging her all vulnerable and exposed from above took on a new urgency when performed in front of a newcomer relatively fresh to the concept of incestuous BDSM exploration, or even Sapphism in general judging by Mrs. Parker's smoldering staring. I felt growling animal lust surging up in me as I disengaged from my Dominant embrace and picked up the handy flogger, however in the interests of the occasion I felt like I had to gloat a little. "Well, Mrs. Parker, observe how beautiful my sweet sister looks when she's restrained like this on the verge of a serious bout of hard Discipline," I said evenly as I twisted my captive sibling face on to our wide eyed neighbour. "What are you going to do to her?" our one-woman audience stammered nervously without taking her eyes of the svelte swaying figure. By way of an answer I held up the flogger and waggled it to get her attention. "You can't do that to her, not in that condition," Parker gasped, although as protests go it didn't seem all that convincing. I reached down between my sister's creamy thighs and inserted a couple of fingers smoothly into her opened cunt then removed them and held them up glistening wet in the bright light. "Apart from the fact she is my possession and I can do anything I wish to my property," I announced slightly pompously, "her arousal is easy to spot and that's just in anticipation of physical attentions. Just wait till you see the effect that a good session of flagellation has, then you'll see my precious sister at her best." It was obviously such a fascinating prospect that our guest fell silent, although the increased motion at her heaving breast spoke volumes and to spur further agitation in both pairs of bosoms present I took a step back and an outstretched arm's swing forward to give my helpless slave the full impact of the flogger's flails across both deserving tits, the crack of leather meeting flesh ringing around the confines of the cellar and combining with my sister's gasp of obscene satisfaction. I let the flogger's tails drop from their momentary hold of her swelling breasts and deliberately trailed them across the curve of her fertile belly before allowing it to fall clear of her straining imprisoned body; then I lingered a few long seconds to let our guest witness the effect the blow had upon my sisters chest, a cute chest that had already suffered its share of torrid torment earlier but was obviously recovered enough for further indulgence. Crimson stripes began to show on the pale curves to match the redness of the hard nipples they framed, and issuing from those lactating teats white droplets appeared as if by magic... I hesitated until the duel milky releases were threatening to tumble down then sent a second well-aimed strike hitting the jutting targets; this time a positive spurt of mother's milk squirted free of those raw nubs, not very far but enough for the full eroticism of the act to be apparent to all. As with all other aspects of my sister's insatiable fetish for pain it was obvious that her lactate glands responded well to such stinging stimulation and the succession of blows that followed had the white flow back up to powerful spurts from sore breasts and the glistening clear flow of arousal streaming down her held parted inner thighs as my captive squirmed against her bonds, her rapid breathing and glazed expression displaying her receptiveness to this deserved punishment. Now that I'd got her tits nicely productive I allowed myself to stroll casually around her beautiful stretched upwards pale body and allowed myself a self satisfied admiration of her chastised condition, taking a slap at her rump affectionately to let her know how pleased I was with her subserviently slutty display. Standing from the vantage point behind my perverse plaything I pulled my eyes from her captivating form and stole a glance back to our increasingly convinced convert guest... She was still stood fearfully with her back to the wall but her morally superior stance was somewhat undermined by the lewd way she was leaning against it with legs bent and pelvis thrust forward so she could reach a hand up her formerly conservatively cut skirt which had rode upwards and was showing off her upper legs handsomely, the hemline now just covering her crotch and whatever frantic activities her exploring hand was performing within. From the openly mesmerized look locked on her increasingly appealing features I wondered if she even realized that she'd been moved to touch herself so blatantly... Her body's obvious desires maybe taking charge without need of conscious thought to direct them. As I pondered this my slave sister moaned slightly from the halt in corrective attention from her Owner and I gave her rear a vicious swipe with the flogger by way of apology; once I started these punishment sessions my sister expected to be taken to the limits of agony and ecstasy and combine the two in the exhilaration of forced orgasm, an intense climax I had no intention of denying her. My hesitation was in trying to think of ways of utilizing this potential pervert neighbour rapidly losing all self control before us. Apart from the alluring appeal of seeing Mrs. Parker give in to sexual abandonment and be used as an instrument in my sister's ongoing depravity training, I was also considering the advantages in having a compliant and compromised woman living next door... This cellar had its limitations, not least it's opportunity for use with our parents around. The divorcee 40-something currently ensnared could prove useful as host for discreet debauchery. With that inspiring thought in mind I set about the final corruption to turn slack jawed voyeur into enthusiastic participant; given the heady aroma of sexual musk exuding from the pair of excited cunts it wouldn't take much persuasion. "Why don't you show my sister how much you appreciate the beating she's just taken, Mrs. Parker," I suggested innocently and whether she'd misunderstood my offer or merely was giving in to her own exhibitionist streak I couldn't say.. The former busy body lifted her constricting skirt above her waist with both trembling hands whilst simultaneously leaning back against the rough brickwork so she could widen her stance more; her tights were soaked in a dark circle surrounding her crotch which betrayed the strength of her arousal and her shameless attitude to letting her teenage neighbours know it. Her eyes had a wild quality behind her rimless glasses and I was certainly seeing Nosy Parker in a fresh light, face flushed and impressive chest heaving for all its worth... She'd managed to dislodge another button and the exposed cleavage was being held in place by a supportive black bra peaking forth above the peaks of straining nipples poking hard against the tight material of her blouse. I longed to see her in intimate contact with the contrasting figure of my slender young sister and was wondering how susceptible the older woman would be to taking instruction when she moved from the wall... I'd underestimated the effect my sister could make when she turned her mind to seduction. My exquisite slut must have given some unspoken signal of deep yearning that pushed Parker over the edge...With a sob of abandonment our neighbour dropped to her knees before my imploringly imprisoned sibling and in a move that surprised me began to lap and nuzzle at her pregnant stomach, her tongue seeking out the splatters of liquid and eagerly consuming it like, well, mother's milk, I suppose. Each to her own, it was a taste that I'd acquired myself recently although I preferred to gather it at its source as was my right as the father and Master. I noticed my sister, whilst preening herself at her ability to attract perverse action, was in need of more direct stimulation and was lifting her hips up as much as her secured position would allow to give the hint that Mrs. Parker's previously harsh edged tongue would be better employed lodged between her thighs. Luckily, kneeling in front of a strung up beautiful whore such as my sub slave usually would inspire similar thoughts and before I needed to push her head where it was required she followed her own repressed instincts and trailed steadily downwards whilst maintaining her mouth and tongue within slobbering range of my succulent sister's smooth skin, down and down to the bald public mound suspended expectantly in front of her until she was low enough to plunge her face deep into the moist invitation that was my fuck puppet's freely flowing cunt. Our Natural Selection Ch. 05 My slave threw her head back between upheld tied arms in ecstatic triumph, a look of greedy pleasure lighting her angelic face up and she rudely began to undulate her hips into Mrs. Parker's face to express the oral frenzy she preferred as I stood back and admired the erotic interplay between the two women unfolding wordlessly. The kneeling Parker was gaining confidence in her new-found talent and was running her face up and down the length of my sister's streaming cunt in tandem with my insatiable slut's bobbing up and down as she swung from her bound position... Mrs. Parker steadied her young lover by digging her fingers into the yielding flesh of her upper thighs and dove deep against the sensitive wet folds of my possession's intoxicating cunt. I marveled at the transformation that had been induced in the staid busy body from next door as she slaked her thirst for sexual discovery at the oasis of my sister and though my own needs were growing considerably as my erection swelled even harder, I let my slave enjoy this expression of demented lust, although I couldn't resist taking position standing behind her so I could cup her aching tits in both hands and continue the milking that the flogger had induced.... I pressed my body forward so I could feel the building up shudders of climax in her bound and abused frame and leaned my mouth to her elegant neck to tease it with my teeth. "You are allowed to cum when you need to," I whispered in my captive's ear between bites, just so she could relax and give herself to the double assault on her erogenous zones, she gave a ragged gasp of thanks as she began to spasm against the pressed neighbourly and brotherly two sided embrace. As always when my irresistible sister was on the verge of climax I felt the overwhelming compulsion to share her orgasm by having my cock buried where in belonged inside her shaking body but our neighbour's newly discovered devotion to cunt eating had a faster effect on a slave already made susceptible to stimulation by the caress of the flogger; much as wanted to drive my impossibly hard cock into either her cunt or ass I contented myself with kneading her tits fiercely; I couldn't interrupt the unnatural spontaneity of events through selfishness. Being Master means having self control as well as complete control of my slave. Besides this pent up lust would be put to good use before the evening was over, of that I was sure. My slut sister was on the verge of cumming hard by now, her trembling restrained body was jerking violently against my chest and I could feel the manicured fingers of the kneeling Mrs. Parker brush against my upper thighs as she took desperate grip on my convulsing slave's buttocks to maintain her oral grip as my sister's hips bucked hard against her face; once again the desire to enter my sister's body filled my mind, to sodomize her with the obliging neighbour splaying the arse cheeks for my penetration, but it was too late, my sister gave a mindless yell of surrender as orgasm consumed her. I gave her nipples an encouraging tweak that sent a satisfying arc of creamy fluid cascading down over the curve of her extended belly and onto Mrs. Parker's back, then I dropped my hands from cupping her breasts and wrapped them bear-hug fashion around her rib cage... Given my sister's delicate condition I wanted her to be held secure and protected in her Master's grip. She convulsed as much as my hug and the bound position allowed as the violent intensity of orgasm hit in wave after wave until she went limp in my arms and slumped against the manacles, my hold on her upper body and Mrs. Parker's on her lower keeping her from serious wrenching of her wrists and arms. There was silence in the cellar in the aftermath of my sister's noises of passion except for her panting from the exertions she'd enjoyed and her lovers both cradled her sated form until she raised her pretty face from its flopped down resting place and whispered her thanks to her Master as was proper... Satisfied she could stand on her own two feet, I released my hold on her and was amused to see the face of Mrs. Parker, soaked with my slave's sweet girl cum, emerge reluctantly from between my sister's smooth thighs. Her glasses were gone and hair was in disarray and sticky with milk, but the most unusual aspect to her normally prim appearance was the lustful look of achievement that lit up her face as she tilted her face up to admire the teenage captive to whom she'd just given the gift of orgasm to. I had to wonder what kind of unhealthy repressed urges had just been liberated, and what further ones we could provoke. It's always nice to give something back to the neighbourhood, after all. "Slave, thank Mrs. Parker for helping you cum," I said without too much mockery and the demur way she mumbled her gratitude shyly was an incredibly seductive performance by my clever little slut... Such was i's appeal that Parker leaped to her feet and was moved to passionately kiss my restrained sibling, their tongues delving deeply into each others' mouths and allowing my slave to taste her own fresh fuck juices. I felt a slight pang of jealousy at this, kissing being the only intimacy that I felt was my exclusive prerogative, but it was a special occasion and the two women made such a delightful contrast: The disheveled older woman fondling the pale and pregnant teen while hanging in her fetters that I couldn't object. Besides, I was reaching animal levels of lust and didn't want to break the spell that Parker was increasingly surrendering herself to. As Mrs. Parker continued the kiss and with growing abandon groped my sister's poor raw breasts with trembling hands I moved close and began to untie the bonds that held my slave's arms above her head and restricted the responses that she could return to the woman caressing her. Once the rope was free of her cuffs her feet were allowed to drop flat on the floor and restore her balance somewhat, although the spreader bar kept her stance nicely lewd. Her freed arms encircled the taller woman and pulled her as close as her pregnant bulge would allow, such was Parker's concentration she didn't realize that the pain whore was unfastened until my slut's hands began to stroke the clothed woman. I was reaching fever pitch by now, my rock solid erection was streaming pre-cum that was a criminal waste as it spilled on the floor...Time to reassert my Dominance. I took a tight grip on my wanton possession's hair and encouraged her to pull her mouth from our brazen neighbour by way of a forceful tug.... My insatiable sister's eyes glinted with renewed licentious fire as she obediently disengaged herself to face me despite the climax she'd only just recovered from; there was no doubting the positive effects of her being an impregnated slut. "Now now, sister, you've been indulged enough for the time being, you must be polite to our guest and more importantly to your Owner... You must be used like the filthy whore you are." My sister understood her obligations at this reminder and couldn't disguise her joy at the prospect, no matter what demeaning form I judged better for her to be made to serve. However, I was too aroused to tease much and without preamble I picked the cushions up from the threadbare sofa and placed them on the billiard table to make it a more level and comfortable flat platform. The implications of this action didn't escape my cock and clit hungry slut and she waited expectantly until I lifted her bodily and sat her on its flat surface perched at the edge awaiting instruction, she being still immobilized slightly by the spreader bar connecting her legs. Mrs. Parker was herself immobilized with confusion in the same spot where she'd been abandoned but I had no intention of leaving her neglected for long. "My fuck puppet is yours to use as well, Mrs. Parker, this evening anyway... We'll have to see what happens in future." I left the offer open and without warning grabbed and lifted the steel spreader bar, raising it up and in doing so tipping my slave onto her back, helpless. Raising the bar higher I admired the view down her splayed legs and the soaking, pouting cunt exposed beneath, the table being exactly the right height that my bobbing cock was now level with its natural haven. I quickly unstrapped the ankle cuffs and cast the bar aside; my understanding sister knew to keep her slender legs held aloft in the same position and I stepped forward to place a trim ankle on each of my shoulders. In moving closer to this ultimate in exposed positions my streaming upturned erection now hovered over the bald pubic mound, a thread of silvery pre-cum trickling down onto the flesh and mixing with the combination of saliva and girlie fuck lube that already coated much of my slave's inviting thighs. I had to feel that unique heat against my cock without further delay, so I laid my hand on my straining shaft and pushed it downward with some difficulty until its length was pressed against the length of my slave's sodden slit, my full balls hard against its entrance and becoming delightfully drenched as they made contact with the unceasing flow. I teased her and myself by slowly edging my hips backwards and letting the vein ridged prick rub firmly along her well lubricated labia until my bulging purple cockhead was nudging her equally engorged clit and the sensation of her jutting hardness was an electric thrill against my most sensitive flesh. I could tease no longer, I had to be inside her so I guided my quivering cock further down until her lower lips were kissing the tip of my erection was she swiveled on her buttocks trying to speed my progress, greedy for penetration. Warmth and wetness radiated down my cock from its slight insertion into my precious Owned whore of a sister and once positioned correctly I took a controlling hold on the legs reaching up against me and with one lewd thrust I impaled her as deep as I could, my cock buried to the hilt inside her clenching cunt until my heavy cum filled balls slapped wetly against upturned arse cheeks. A surge of pure sexual energy shot through my body... Everytime I violated my sister it felt as exhilarating as that day I'd took her virginity all those months ago; I could never tire of feeling that velvet grip envelope me and know with full certainty that she was mine and I'd guided her into the depravity that had transformed her into the submissive slut and insatiable dedicated whore currently smiling up happily at her big brother; her impregnated belly bulging upwards as a swollen constant reminder of her deviant devotion to her true Master. I held my cock deep into her, feeling her cervix squeezing against the invading member, then I started to slowly pull back, savouring the hold her tight teenage cunt exerted upon my throbbing rod as her internal muscles tried to keep me lodged inside giving her... as if I had any intention to withdraw. As I was nearly clear of her body I gave a brutal lunge slamming back into her that sent shivers of pleasure through my frame and a yelp of joy escaping the lips of my succulent sibling, her back arcing under the impact despite the fullness of her fertile belly. This slow toying with her was not only an exercise in massive self control on my part, I was sending her the signal that I was going to pace my enjoyment in fucking her so she could build up to yet another climax. I not only wanted to cum with my pleasing possession, but I had ambitions for Mrs. Parker to reach that ultimate satisfaction with us; I'd been so taken with getting my slave on her back for her Master I'd neglected my duties as host. I tore my gaze away from the beautiful sprawled body whose loins were being punished by mine with slow, deliberate strokes and glanced up to where we'd left our dazed neighbour. Even tho' I'd already given her permission to let her liberated libido take charge she was still hesitating stood where we'd left her, although she made an enchanting portrait of temptation overcoming all other considerations. Seeing my eyes lifted to her she made an unconvincing attempt at regaining her dignity. "You're having sexual intercourse with your sister," she croaked as if the prior use of the flogger upon her breasts had held some innocent explanation, or indeed she wasn't stood there with my slut's fuck juices still on her lips. "She's my slave....my willing whore....too attractive not to Own and fuck," I said, my speech punctuated by accompanying pelvic thrusts and the slap of flesh hitting flesh. "I recognized her....need for deviant sex....and I encourage....her continual depravity." "It's so wrong, lusting after her, especially since she's pregnant," she breathed, her eyes betraying further dark desire "Let her who.....is without sin.....cast the first stone," I grunted, my erection pummeling hard, deep and solid into my cock hungry slut who was swiveling her arse to the rhythm desperately to maximize the penetration as her hands occupied themselves pulling on her own nipples to spur on her arousal more. "It's so wrong, it's so wrong," Parker was muttering to herself, but since she'd also began to claw at her rumpled blouse, her skirt already falling to the floor I figured that I'd convinced her to follow her instincts. She shrugged off her outer clothing and had her tights and underwear stepped out of with unseemly haste... Both I and my reclining sister admired the sight of the last of her willpower dissolving and this eagerness to give herself to sinful indulgence. Whatever life of pious restraint she'd led to date it had to be observed that it had done wonders for her physique, despite probably being as ancient as her late 30's. Once the air of frosty moral superiority had been cast aside along with her clothing, the voluptuous near naked woman revealed was worth appraisal, her smooth tanned and toned body being a corset designer's dream: an hour glass figure who's shapely hips, flat stomach and impressive cleavage still imprisoned in her straining bra was better employed in the service of perverse gratification rather than serving any religion. I maintained my piston-like ramming of my excited little sister whilst we watched Mrs. Parker's clumsy strip, stretching her to the limits as sexual anticipation and adrenaline urged me on... Our formerly prim and proper neighbour was obviously emboldened by our acceptance of her scrabble to become as naked as we were: She strode on long, well shaped legs to the side of the table opposite my position where my libertine sibling was straining her neck to keep her in sight and without a care bent down to capture my tantalizing slut's mouth in an upside down kiss, her hands fumbling in exploration to brush aside my sister's tweaking fingers and replace them with her own. This passionate display so close at hand was gnawing away at my self control, but I owed it to all concerned to keep my lust in check and prolong this unique situation. Besides, my licentious little slave was making her ever present need to serve known. Her slim arms were reaching back and groping at the older woman, trying to pull her closer until in frustration she pulled her face away and gasped, "Use me, use my mouth, let me make you cum". I would have thought a lady as dignified as Mrs. Parker wouldn't have understood such a heartfelt plea, but without hesitation she had clambered up onto the table and was throwing a leg over my laid flat slut in order to straddle her so innocent looking face, lowering herself carefully until her dripping cunt was positioned squarely over my sister's talented mouth. Maybe Parker retained a shred of shyness for she was kneeling with her back to me, which under the circumstances I thought a trifle rude considering I was letting her enjoy my slut sub so kindly, but, as always, if my sister was the center of attention I was content for her to enjoy the debasing treatment and lustful usage. Besides, even if I was cheated out of witnessing our fallen neighbour's expression as my sister's artful tongue snaked out and lapped contentedly into hot wet cunt it was always a pleasure to see my wanton little slave giving into the exhilaration of being the perfect whore, especially since I had my pounding cock where it belonged buried inside her. I know from the juddering of her lithe young body that she was in the grip yet again of approaching orgasm and even with the sight of her mouth fully engaged in its vital work I knew I could hold myself in control so I'd cum at the most opportune moment... The feel of my sister lost to ecstatic release was all the trigger I needed, but the real result would be if my clever sub could coax the woman squatting on her face to join us at the same time. I need not have worried, my energetic sex slave used the glorious build up of approaching climax to redouble her assault upon the God botherer having a different kind of revelation astride her face. Mrs. Parker had been rocking herself to and forth using my sister's active mouth where it was needed, from clit to asshole and back as the exuberance of sensation set her body aflame in ways that she could only have dreamed of; now my inflamed slut reached up and took hold of Parker's buttocks, sinking her fingers into firm flesh and directing her hard down onto her attending mouth. From the position of the gnawing chin framed by shaking buttocks I could guess that my sister was concentrating all her oral skills solely on her new lover's clitoris and this theory was confirmed by the squirming response that it elicited; Parker shrieked at the unaccustomed intensity and mindlessly tried to escape, but my sister's arms were coiled around the kneeling thighs and held her in position to succumb to the feeling of teeth chewing upon clit. Even with just a rear view to judge by it was obvious to me that both women arranged one atop the other before me were in the final furlough before orgasm and I increased my fucking motion to accommodate my most deserving of slaves, my long delayed excitement finally taking me in that familiar grip of crude nihilistic compulsion to make my sister mine in the most basic of ways. She was taking no chances in ensuring that a 3 way orgasm was employed, above her writhing body with its extended belly and reddened breasts I watched her reach her grip round the splayed thighs smothering her and slide slim probing fingers simultaneously into Mrs. Parker's well lubricated cunt and asshole and match the brutal thrusts that I was slamming into her with rising speed. Witnessing this lewd violation was the final straw for me; it was as if I was fucking Parker through proxy and my head swam with the beauty of my sister's depravity... I lifted her arse clear of the table's edge as I slammed my cock mindlessly and repeatedly into her yielding tautness... A female screamed in ecstasy and a far away realization told me it must be Parker because my sister was muffled by her, but there was no mistaking that my sub was also in the throes of climax by the violent convulsions that her body was attempting, restrained tho' it was at both ends. That was my cue to give myself to the bliss of filling my sister with fresh loads of incestuous seed into her wide open womb; my legs buckled under the intensity of the sensation as I shot hot cum deep inside her and kept the fucking motion going in a desperate attempt to keep the moment of rapture alive as long as possible... It could never be long enough unfortunately, but my squirming sister was made of sterner stuff and as Mrs. Parker weakly rolled off her soaked face and collapsed panting by her side my never disappointing possession still had the capacity for further pleasure. Even as the last ejaculation entered her and my head began to clear she was still making mewing noises, her scrambling fingers mindlessly reaching round her belly to find her clit and keep the flow of multiple orgasms maintained. There was no danger of me becoming flaccid after the events of the evening so I forced my body hard against her and continued to grind my loins into hers, enjoying her orgasmic aftershocks clenching on my raw cock and I fucked her into total submission until even she could take no more undiluted sensation and she indicated at me to stop, her face aglow with sweat, fuck juice and achievement. Our Natural Selection Ch. 05 I unhooked her ankles from my shoulders and let them fall either side of my hips, but pushed my still erect cock fully into her and held my pelvis against her to lean forward and stroke her sweat sheened belly, breasts and face affectionately like the good fuck pet she was; I wanted to kiss her silky lips as I always enjoyed in the post-coital calm, not least because her mouth was shining with Mrs. Parker's copious juices and I'd have enjoyed comparing the taste from such a charming surface, but stood as I was inside her the bump of her stomach made that difficult, so I caressed her flushed cheek instead, trailing the older woman's lube into my slave's mouth and allowing her to suck my fingers. In my volatile state this simple act of submissive devotion sent shivers down my spine and sent renewed strength to my continuing arousal. My beautiful sister was looking up at me with clear blue eyes as she sucked my fingers; she knew exactly the effect she could have on me and that wicked gave spoke volumes—she still had the capacity for indulgence. The unexpected opportunity that had arisen with our nosy neighbour's curiosity getting the better of her just had to be extended a little longer and I already had a final chore planned for our former beacon of morality, which is why I'd remained sunk to my balls inside my slut slave. (As if I needed an excuse.) I glanced over to where the sprawled older woman had collapsed laid on her back; her bra had come unfastened during her oral ordeal and her firm round tits were rising and falling as she recuperated, from between firm thighs a flow of lube to rival my wet slut sister's was trickling down between her buttocks and staining the green felt of the billiard table. I'd have never forgiven myself if I hadn't taken advantage of her new found descent into self debasement; it wouldn't do for her to be given too much time to recover and let that old demon Guilt get a grip, so I carefully withdrew my erection from my happy sibling and quickly swiveled her body 45 degrees so she lay the full length of the six foot table, her lower half swung in Mrs. Parker's direction until her thigh knocked against the older woman's reclining body, the contact of flesh against flesh breaking her dazed reverie. "Cleanliness is next to Godliness," I reminded her and as if on cue the first seeping of my cum began to escape from my slave's tender pouting cunt and slowly flow down between the crevice of her buttocks. The freshly baptized pervert needed no further instruction and my obliging sister lifted a leg to allow her to crawl between her widely spread thighs and dip her head to that oozing opening that had just drained my balls. "Oh yes, lick me clean, lap up my Master's cum!" my shameless slut cooed happily, reaching down and taking her new admirer's dark hair in her hands to assist in the task. 'Such brazen wantonness,' I thought proudly as I climbed up onto the sturdy table and pressed my dripping but not drooping prick against my sister's sweet mouth. Instantly her soft lips encircled the raw purple bulb and sent quivers of radiant bliss pulsating through my body again. I let her active tongue dart around my most sensitive flesh, then gently disengaged my throbbing member so I could lay the shaft across her mouth like a living Bit gag... she obediently laid her head flat against the table surface looking straight up and pursed her lips around the underside of my shaft so I could glide it's length slowly across her lips and let her taste her own fuck lube that covered its entirety. When this delectable cleaning progress reached the base of my cock I tilted her head towards me and forced my testicles to her face; she ran her tongue across my equally sticky scrotum with greedy relish, purring contentedly as Mrs. Parker acquired the taste for cunt flavoured cum, sucked fresh from a previously fertilized womb. Having my balls tickled by my mischievous sub's dutiful tongue was doing nothing to make my heightened state of arousal lessen any... The insatiable whore was now really tugging Mrs. Parker's face against her wet cunt as if the spate of orgasms she'd wallowed in over the last few hours hadn't been enough, but she was a good slave and I couldn't deny her further gratification. Taking her own flame red locks in my hands I guided her mouth back along its vein ridged length until I could drive the swollen head back into her mouth.... I knew how having her face fucked with lustful abandon turned her on and I was prepared to make this sacrifice in order to achieve further debauchery for my dear sister... She began to moan as much as she could with a mouthful of thrusting cock and I could imagine that Mrs. Parker's lessons in cunt eating were having the desired effect. Even if I wasn't ready to cum again I was looking forward to feeling my slutty sibling orgasm again with my erection buried inside her mouth, so with a contented sigh I increased the pelvic thrusts into her angelic face... It was going to be a long night if each deviant act continued to contribute to this upward spiral of inspired degeneracy, still as I'm sure the pre-corrupted and compromised Mrs. Parker could have testified to, there is no rest for the wicked. Our Natural Selection Ch. 06 I pulled the fresh crisp sheets up to my sleepy sister's chin and tucked her in affectionately as she smiled up at me sweetly and bent her face up for a final goodnight kiss which turned passionate as our tongues slithered against each others' and darted into mouths betraying the true incestuous nature of our relationship despite the innocent nature of my good natured putting her to bed. To think that those silky lips I reluctantly broke contact with had been so active so recently... and even after enjoying a full program of perversity my cock gave a lurch to see my little sister laid in her 4 poster bed with a blissfully sated look on her angelic face as she contemplated her latest amorous achievements. What had started as our taking advantage of our parents' absence to indulge our incestuous BDSM relationship had taken an unexpected turn by the intrusion, temptation, corruption and seduction of our previously morally unassailable neighbour Mrs. Parker who'd taken to throwing off all self restraint in favour of exploring the virtues of unrepentant sins of the flesh... But who could blame her when that flesh comes in the form of my joyously sinful eighteen year old sister, heavily impregnated by her big brother and reveling in every new punishment and perversion I can introduce her to? I smiled down at the beautiful slut snuggling down into her pillow and longed to whip out my stiffening cock to plunge back into her always hungry to serve mouth, but our parents had returned and we were back into the unreality of our normal pretense. Luckily, we'd bid goodnight to our new recruit to debauchery and sent her back next door shortly before they had showed up. My enslaved sister had been showered and made to look respectable just in time and I'd made a point of showing what a supportive brother I was by helping her turn in. If our parents could have read minds or witnessed my pregnant sister sprawled across the snooker table down in the cellar earlier happily lapping my cummy cock clean whilst our newly converted to carnal excess neighbour lay between her splayed thighs devouring my freshly inserted jizz fresh from the cunt where I'd deposited it... Despite the fucking, sucking and flogging that my glutton for punishment possession had endured up to that point she'd still grabbed hold of Mrs. Parker's hair in order to mash her face hard into her squirming loins and I'd enjoyed that exquisite sensation of having my slut of a sibling orgasm violently with her mouth full of my appreciative member. At this point I'd been forced to introduce an element of sanity into the proceedings given the lateness of the hour; being caught in a compromising position with my kid sister by our unsuspecting parents would be bad enough, to be involving the pious pillar of the community from next door would be too much and the evening had been so perfect that I wasn't taking any chances of being discovered. So Mrs. Parker was encouraged to remove her face from the oasis between my slave's legs and she looked a picture of born again hedonism with her normally reproachful features coated with my sisters fuck honey, which I could testify was extremely addictive. I swung myself off the sturdy table and began to collect the various incriminating instruments of torment and hide them back in the recesses of the cellar whilst my sister struggled up into a sitting position whilst holding her rounded belly and moved close to her new lover, still slightly dazed by the intensity of filthy emotions that had led to her casting off all pretense of morality or chastity in such a dramatic fashion. She took the older woman's head in her tiny hands and pulled her close to enjoy a lingering kiss that was flavoured by the mix of our sexual secretions on Mrs. Parker's mouth. I picked up the discarded clothing that Parker had eagerly wriggled out of in order to join in the defiling fucking of my expectant and lactating sister and politely placed it next to her whilst watching the level of passion rising again between the two women; my Owned slut had caught hold of the voluptuous older woman's breast as they kissed and was kneading the firm roundness with one hand whilst sensuously rubbing her own smaller but perfectly formed tits against the other in a move that was doing nothing to calm down our nosy neighbour. What with my sister's insatiable sex drive and need for depravity intensifying since being impregnated and Mrs. Parker's years of repression coming tumbling down like the walls of Jericho, I could see that I was going to have to be the unwelcome voice of reason and dampen down the flames of lust that were already taking hold; my sisters hand had snaked with purpose down to the older woman's lap and was unhooding the swollen clitoral nub it located there with ease whilst Mrs. Parker had hold of my sister's collar and had pulled her away from the kiss in order to bend her face down to catch one of her productive breasts between her lips and was nuzzling at the nipple obviously hungry for the milk that needed little urging to be expressed. "Enough." I ordered against every instinct in my body and my obedient sister instantly straightened up, much to our ex-bible basher's dismay. Gently my seductive sister disengaged herself from the older woman's embrace and I helped her off the table. She stood shamelessly servile by my side, her slender succulence and swollen belly gleaming under the coating of saliva, sweat cum and female fuck honey that enhanced her glow of depravity so blatant... Without thinking, I drew her closer by her ever present collar and fondled her as I addressed the still reclining naked woman wantonly admiring my sister without a trace of guilt, her eyes still smoldering with the unholy zeal of one who's just seen the light. "Well, Mrs. Parker, I'd say your conversion and baptism went well; my delicious sister is certainly deserving of being worshiped with the devotion you've displayed today, but you must remember that she is my property first and foremost and, whilst I'd never deny her the slightest sexual indulgences, my Ownership of her means I must be in overall control. Do you understand? You may play with her but only with my permission, if not my supervision." Parker digested this information and it obviously held some slight appeal for she nodded with a hungry smile and my always indulged sister gave a happy squeal at this addition to her circle of lovers and I allowed her to kiss our convinced neighbour enthusiastically and help her dress. As she resumed her outward appearance of respectability she talked freely as the realization that the sexual intensity she'd just experienced would be repeated... As expected, her neighbourly surveillance of my sister and I had led to her suspecting that we shared more than most siblings and her imagination over the months since I'd enslaved her and impregnated her she had become obsessed with the taboo nature of the depravity unfolding next door to her. When our less-than-discreet noises of perverse passion had been heard by her once our parents had departed, the final threads of doubt had been swamped out by a lustful need to intrude and she'd thrown caution to the wind by sneaking into our home hoping to observe all the debauched acts that had haunted her imagination for so long, little expecting to be allowed to participate with such blissful abandon. I explained to her that she'd hardly scratched the surface of our forbidden brother/sister, Master/slave activities and now that she'd been inducted into our secret world of licentious indulgence she could expect us to be visiting her home frequently; a prospect that sent her on her way with a gleam in her eye. Then it was just a matter of escorting my slave to shower where I joined her and since she was exhausted once the adrenaline and endorphin rushes were wearing off I washed her carefully and she accepted this unusual treat joyfully. I could tell she was replaying the events of the evening through her wicked mind... the contented look on her face was making me concentrate my soaping motions between her legs and I was just looking forward to having her cum again under the administrations of my slippery stroking fingers when the sound of our parents' car pulling up outside was heard over the noise of the shower. I leapt from the bathroom and was safely dressed in my bathrobe with an innocent air about me when they entered, leaving my slutty sister to finish her shower unassisted, although I was fairly sure she wouldn't have been able to resist frigging herself to a final climax whilst still wrapped up in the memories of the evenings successful activities. Replaying the recent events of the evening combined with the angelic countenance gazing up at me with sleepy contentment had me once again hard as a varnished eel and despite the fact that conditions were far from ideal I knew I'd never forgive myself if I didn't perform one last act of gross indecency upon my lovely slut of a slave. The fact I was still wearing only a dressing gown meant my rekindling erection was obvious and my knowing sister had been taking a growing interest in the growing cock rising to the occasion and trying to poke itself free... I pulled my robe open in a trice and was rewarded by a dazzlingly happy smile lighting up my insatiable sister's face as my solid prick bobbed free above her reclining figure. Some family gene or the fact that we shared such a taboo taste meant that since enslaving my sibling my pre-cum production was greatly increased, tho' nothing approaching my lascivious sub's constant flow of fuck honey; as my achingly hard erection strained free, a trail of clear sticky fluid seeped out of the bulging purple head and slowly began to trickle down clear of its source. Maintaining eye contact with my kid sister I deliberately guided my cock over her waiting face just in time for the slow decent of fuck lube to land on her pretty lips. She joyfully accepted this token of my amoral affection and kept her mouth sealed until the flow had built up enough to start to dribble down the side of her cheek before seductively parting her lips and running her tongue round them carefully to savour every drop of my apparently sweet man sauce. The little minx knew exactly the effect such a slutty display would have and since any erection she inspired would be criminal to waste I bent the tempered steel organ downwards as much as was possible to increase the flow of lubricant into her ever greedy mouth whilst allowing my grip to ease my foreskin clear of the swollen purple prepuce hovering so provocatively over my angelic possession. With mischievous intent my impregnated personal whore snaked a slim arm clear of the cozy security of her bed sheets and reached up to caress my recently replenished testicles hanging above her in an instinctive gesture of sexual servitude. Her slender probing fingers gently massaged my love spuds as if desperate to squeeze every possible drop of incestuous goodness up into her waiting mouth and I luxuriated in the delightfully wrong sensation. The increased flow of Dom lube was running down the shaft of my bobbing cock and I shifted my stance so the stream could continue into my sister's greedy mouth once it trickled clear of my bollocks; mere centimeters above her lips. The feeling of my slut's active fingers smearing my scrotum with the excess fuck juice was driving me wild and I knew the only thing better than her talented digits would be her wicked tongue distributing the sticky liquid, so with a hoarsely whispered command to "lick your Master" I thrust my pelvis lower to straddle her mouth lightly whilst guiding her little hand upwards to envelope the taut flesh at the top of my over indulged cock. It was a slightly ungainly position I found myself in, semi- squatting over my slave sister's face with legs bent for best effect, but the electric waves of pleasure surging through me overcame all self-consciousness, and indeed all sense of discretion, considering our parents were in the house... but I'd never forgive myself if I didn't give in to the head spinning lust that she never failed to inspire. Bent awkwardly as I was meant that I could now reach under her blankets and my outstretched hand skimmed the hot tight flesh of her upwardly curved belly as I sought out the smooth heat of her bald cunny; I was delighted to discover that not only was my deviant sub sister as wet as expected but the fingers of her unoccupied other hand had beat me to the hard pleasure center of her rigid clit. I laid my hand on top of hers in a brotherly gesture of solidarity and let her active fingers work both of our most sensitive bulbs. The sharp tips of my teenage fuck toy's fingernails swirled across my shuddering swollen glans as our joint manipulations of her sweltering cunt pushed her into a higher sexual gear and conscious of the risk of such blatant perversion being intruded upon, combined with my own rising urgent needs, I gripped the veiny stiffness of my shaft in my unoccupied hand and began a slow wank with a rhythm that I matched with my two forefingers sliding into the tight, wet confines of my sister's vagina once again. With mounting passion we attacked each others' and equally our own sexual organs, both raw from the excesses of an evening whose depravity we were obviously reluctant to put to an end. Long reckless minutes were spent in this compromising position, the silence of the room overwhelming as we desperately stifled our increasingly heavy breathing and strained our ears for warning sounds of parental approach until the ecstatic sobs escaping my totally corrupted sibling's lips, now brushing my quivering cock head, told me that she was past the point of caring and she was about to cum hard and long without any sense of discretion left to hold her back... This was the trigger I'd been holding myself back for and my fingers increased their harsh torment of her G-spot as I dipped my purple cock head fully into her slack mouth and effectively gagged her cries just in time Even in the throes of climax my personal slut instinctively accepted my pulsating penis and worked its smooth sticky flesh with her tongue. My fingers were pounding into her and holding her down at the same time as her pregnant form jerked wildly under the layer of blankets; it was unusual to watch my depraved slave orgasm without being fully exposed and naked but the clutching constrictions her velvet cunt was making upon my fingers was in tempo with the sucking vacuum surrounding my orally pampered prick and I could not hold back another second: With a low groan I relaxed into the orgasm, ignoring the sudden desire to throw back the sheets and ejaculate over the spasming impregnated and lactating body of my partner in debauchery and cover her hot flesh with heavy splatters of my incestuous spunk as yet another tribute to her unhesitant and joyful degradation at my hands. However, common decency prevailed and instead my body cramped with euphoric release as I pumped shot after shot of jism down my obliging slut slave's throat, releasing the grip on my jerking cock safely secured in her mouth to steady my balance by grabbing told of my flame-headed whore's locks just in case her well trained gag reflex took over. I needn't have worried, even in her current agitated state she took my full load smoothly, the seed that had made her my breeding slut now filling her belly from the opposite direction.
