Discovering sister's errogenous zones

Note : This story is completely fictional!

Josh and Amanda were much closer to each other than most siblings. One of the main reasons for this unusual bond they shared was due in part to their losing their parents in a car crash in the South of France when the children were still only toddlers. And as a consequence of this tragedy befalling them they were sent to live with their mother’s older sister Aunt Beverley, who, although very wealthy chose to live a frugal existence with just her cats and dogs for company, in a very remote part of Scotland, near Loch Lomond.

They were at ease with each other’s nudity and up until fairly recently would think nothing of sharing a bath or just lying in front of the open fire talking or watching the television, naked as the day they were born. Their Aunt was also very comfortable with her own body and was most times unclothed whether sunning herself in her huge garden or perhaps riding one of her seven horses.

Josh was now eighteen years old and Amanda was just short of her nineteenth birthday. With their schooling being done at home; under the tutelage of Mrs Walpole, an elderly spinster who had retired from teaching. With the nearest school being over fifty miles away this was both a godsend education wise. And a hindrance to the young sister and brother where meeting other children was concerned.

For a lad of such a young age he had quite the biggest penis that his Aunt had seen for very many years. As for his sister, never having seen a penis apart from Josh’s, she had no clue as to how large it was, she thought it rather wonderful looking though, especially on the odd occasion that Josh had become erect when she was cleaning his back in the shower, or perhaps as he woke up in the morning with a hard-on, that would protrude from his young loins sticking out like some massive veined bulbous flag pole.

Amanda had developed into quite a beauty. Flaxen tresses cascading down her back and perfectly formed neck towards her pert bottom. Struggling to gain the advantage and climb past the two magnificent jutting orbs, her hair settling on her breasts, where the longest part of her mane covered her teats that were erect as chapel tent pegs. Josh was very fond of caressing her tits but now since he was starting to experience feelings of a burgeoning sexuality he was becoming ever more obsessive about his sister’s vagina and she in turn was full of lustful thoughts for his cock.

“I have to go away for several days” said Aunt Beverley to the fully clothed siblings.
“I don’t want to but I gotta see, so you two will have to fend for yourselves ’till I get’s back.” Secretly these words were just what Josh wanted to hear and he felt his organ beginning to strain against the confines of his underpants. The thought of some carnality was making Amanda’s cunt moist and neither one could wait for Beverley to leave the house the next morning.

As they waved their Aunt goodbye the two “horny as hell” youngsters ran upstairs to the master bedroom. Amanda’s mouth was forcibly thrust onto Josh’s willing lips. Their tongues intertwined like two slippery eels in a dance of death.
Divesting their clothes their naked bodies squeezed tightly together in lustful congress.
“Oooh it feels so hard let me suck it for you dear brother.” and as she finished saying these words she opened her mouth wider to ensure accommodating Josh’s big cock and in one swift movement she skilfully deep throated him right the way down his engorged member to his balls, that were now resting on her chin.
“Mmmfff slurp mmfff” were the sounds emanating from where Amanda’s head was bobbing up and down at her brother’s crotch.
“Ooohh sis that feels fucking wonderful…..aaahhh yes, sweet Jesus ooh.” and Josh’s eyes squinted slightly as wave upon wave of pleasure surged through him. Josh could feel that sensation he knew only too well since discovering masturbation. He could not hold back unless he pulled his dick from Amanda’s blood red lips. This movement of retrieving his close to bursting penis from the oral receptacle that was about to receive a whitewash took tremendous willpower from one so inexperienced. But pull out he did and in turn threw his sister down onto the king sized bed.

“Slurppp mmfff slober” were now the noises coming from Amanda’s snatch as Josh showed that having a big cock wasn’t the only way to cause a woman to cum buckets, also having a long dextrous tongue would just as easily turn the lucky female to mush. Amanda lay back on the bed and received untold pleasures from the darting probe that was Josh’s second largest appendage, flicking in and out of her cunt, moistening her clitoris in readiness for what was to come.
“Be gentle with me Josh it is my first time.” and with those words still sounding in his ears he positioned his mighty organ at the entrance to his sister’s sopping wet vagina and slipped all the way up into her love glove all the way to his bollocks that had tightened within the sack prior to the imminent explosion of hot sticky globules gushing out from his bell end into Amanda’s most secret place.

“Yessss oh yes that’s it ohh yyessss!” Amanda cried out as Josh now mauling his sister’s breasts roughly, and slapping her hard on her arse speeded up his thrusting in and out of her cunny to such a pace that it was almost a blur before:-
“Aaahhh yessss fucking hell……….yyesss!” Josh sweat dripping from his lithe young torso clamped Amanda so tightly she could hardly breathe as he ejaculated into her.
