For as long as I can remember I had always been a 'Big Boy' yet the knowledge of me being somewhat different from my peers prevented me from flaunting my considerable assets, and in fact I was quite self-conscious with regards to my unusual anatomical dimensions and always endeavored to keep my 'little' secret well hidden.
That is of course until the fateful night of my 18th birthday party, when I'm afraid I had drunk a little more than was good for me and was eventually helped upstairs by my Mom in a virtually semi-comatose state. She eventually got me on the bed and like any dutiful mother began to remove my clothes.
She had imbibed quite freely herself that night and her previous maternal inhibitions had somewhat deserted her.
I suppose that the sight of a near fourteen-inch semi-erect penis straining at the fabric of her son's shorts finally caused her to flip and when I finally came round at what I imagined to be the climax stage of a 'wet dream', it was to find mom gagging with half of my cock stuck down her throat, vainly attempting to swallow the copious flow of semen that was pumping from the bulbous head and failing miserably as it bubbled and dribbled from the side of her mouth in thick gooey grey-white tendrils.
I instinctively reached for her breasts which had partially slipped from her flimsy party bra'. It required little effort to free them completely and although she had just turned 39 her tits were as pert and firm as a woman half her age and I felt the hardened nipples grow under my lustful ministrations.
I think we both heard the partially suppressed girlish giggles at about the same time and I looked up from my nipple nuzzling to observe my two older sisters, Carol and Connie, now dressed in their provocative baby doll PJ's, gazing in awe and envy at the spectacle they were salaciously observing.
With some reluctance, mom freed her generous mouth from my still gently oozing cock but kept a firm hold on the pulsating shaft as if afraid that it would vanish if she let go.
A momentary flash of concern darkened her face on realizing that her daughters had caught her in such a compromising and incestual situation with their younger brother.
She grinned sheepishly; wiped the worst of the dripping cum from her face then offered up my cock to the now advancing duo as if she were serving them meat loaf at the dinner table.
Being dutiful daughters they accepted the invitation to taste the meaty delicacy with unrestrained alacrity. Pushing mom unceremoniously aside in their eagerness, Carol began to lick away the final traces of the thick semen that coated the swollen head of my penis, whilst rhythmically jacking at the fast hardening vein-studded shaft.
Connie meanwhile, with a combination of soft full lips and long slender fingers, was doing things with my balls that set my pulse racing and within moments I sensed the largest erection that I had ever experienced and my previously reddened glans had now turned to a deep shade of purple and throbbed ominously.
My two rather skinny-assed siblings had by now lost any inhibitions that they may have been harbouring and with total abandonment had cast aside their flimsy night wear and were rewarding my lascivious gaze with glimpses of their slender but well toned bodies.
Both had tits that were relatively small but perfectly shaped and topped with hard full nipples that had both the size and colouration of ripe morello cherries.
I was also visually rewarded by fleeting glimpses of shaven pubic regions that more clearly revealed full smooth but barely perceptible labial mounds that parenthesised the long straight slits of youthful vaginas, now becoming slick with beads of feminine juices and broken only by the fleshy prepuce that housed each precious clitoris.
As I reached out to caress first those young, firm and sensual breasts, my olfactory organs were invaded by the heady and musky odour of more mature feminine juices and I was somewhat surprised to see mom, now straddling my face and manoeuvring her equally delicious pussyy over my mouth.
It could have been the blueprint of either of her daughter's pussies except that her outer labia was more pronounced and the inner lips more voluminous, with the outer edges a much deeper shade of red. Her prepuce hood was also agape revealing a quite sizeable clit that was surely made for sucking.
As my tongue passed across this ostensibly female organ before sinking deep into the warm and inviting vaginal cavity, I felt mom shudder as if receiving an electric shock and suddenly my mouth was filled by hot juices that were literally spurting from deep within her and I realized then that the female orgasm was no fantasy and I quickly devoured the sweet translucent cum that were now propelled into my appreciative mouth. "Oh Danny -- I can't stand this any more," moaned mom softly in my ear.
"I know it's wrong but I must have that beautiful big dick inside me."
The girls sensed her overpowering desires and deferentially removed themselves from my cock, which immediately sprang to full attention. With somewhat improper haste, mom opened wide her shapely legs and lowered herself onto my gargantuan erection.
With surprising ease, which even made the girls gasp, a good ten-inch vanished inside the now gaping maw with nary a hint of resistance.
It was pretty obvious that she was no stranger to super sized willies and as I later learned my pop, who some ten years ago had run off with a pretty college sophomore, was no slouch in the dick department.
The next couple of inches demanded a little more effort on my part and I gently but firmly pulled her further onto me.
She gasped a little but bid me continue and so with a number of deep penetrating thrusts I was able to insert the full 14 inches.
She looked at me apprehensively and I nodded in anticipation of the unasked question that my cock was fully housed.
Slowly she gyrated her hips as if making further room for the fucking that was about to commence. The circular grinding gradually evolved to perpendicular oscillations that quickly gathered pace until my huge cock was pistoning in and out of mom's pussy at a frightening pace.
This erotic act was all to much for the girls who were now squealing in sexual excitement and frantically sought each others vaginas into which they were vigorously pumping multiple shaking fingers.
Having previously shot my first load of the night, the now frantic fucking was a little more sustainable and it took a good five minutes before I sensed the familiar tightening within my dangling scrotum.
"Oh! Mom, Mom, I think I'm going to come!" I hollered somewhat poetically. Mom was also now totally bereft of inhibitions and screamed in response,
"Shoot that sweet cum deep into my burning cunt Danny and then fuck me hard again in my asshole."
Now this request may have caused problems for older guys but when you've just turned 18 then the practicalities of such a demand become much more feasible.
In tandem with Mom's orgasm, I duly sprayed her stretched pussy with my hot seed and with somewhat undue haste withdrew my still fully erect cock, whilst mom obligingly assumed the 'doggy' position.
Eager to assist, Carol and Connie began to lubricate mom's anus with a combination of our slippery fluids. Eventually their lusty ministrations had opened the petal shaped orifice to the degree where my huge glans could partially penetrate. With a strange, demented look, mom now turned to me and demanded passionately,
"Now fuck my sweet ass Danny -- hard and deep."
Needing no further bidding I thrust that great head into the heart of mom's ass and geed on by the demented cries from my siblings I continued the savage thrusting until I had fully penetrated her.
This left, much to the delight of the girls, about four inches of cock protruding, which they rapidly seized upon with their hungry mouths.
The added stimulus stiffened my penis to a new elevation and as it slid in and out of that ever-expanding cavity, the sex-crazed duo slurped greedily at the thickly coated member.
After eventually depositing a further copious load of cum deep inside mom's asshole, the rest of that long eventful night was spent in performing a number of sexual exploits with mom and the girls, the latter being happy with just blow jobs, tit shags and fingering, especially after seeing the size of mom's poor asshole after my third invasion that fateful night. This happy turn of events continued for a further couple of years on a near nightly basis and mom, quite happily I must add, took the brunt of actual copulation.
Only once did I manage to persuade Connie to let me shag her but unfortunately her screams of protestation after taking little more than about 8 inches put the pair of them off any further attempts at 'brother fucking'.
I guess it was these regular sessions that stimulated further penile growth and by my 20th birthday the size of my cock equalled my age. Fortunately I then appeared to stop growing. I suppose this happy state of affairs could have continued indefinitely and undoubtedly would have until that fateful day I met Jenny.
Jenny was all that any man could desire, including the fact that she was a virgin. Her family belonged to one of those bizarre sects who steadfastly believed that sex outside marriage was strictly taboo, so due to her authoritarian upbringing our courting period consisted of much gentle kissing; the occasional feel of a bra' constrained tit and just once a furtive glimpse of a heavenly pussy that I stole when she had fallen asleep once while watching TV.
However, her beauty was such that I believed that anything more than 'kissy feely' was worth waiting for, besides I still had access to a trio of opportunities through which I could vent my sexual frustrations - and boy! Did I take advantage.
The day we married was quite eventful but not perhaps in the way you would have imagined. Mom and the girls broke into fits of uncontrollable sobbing when I said 'I do' and I can't for the life of me imagine why.
Jenny's father was also quietly sobbing, which was also out of character as he always appeared to be a rather jolly chap but had been strangely silent and subdued since we had earlier occupied adjacent urinals before entering the church.
But all of this paled into insignificance compared with Jenny's strange behaviour when we were finally alone in the bridal suite.
