He could happily have stripped off all the clothes of conformity and gambolled around in just his boxer shorts. Yet Matthew had been raised a conservative fellow, unaccustomed to nudity. Mae-Lin was the first and only woman he'd witnessed naked. That merely intensified the longing for a girl his own age to strip naked, to let him touch her firm breasts and do all the things that horny twenty-year olds dream of. A sagging middle-aged woman hardly bore comparison.
It was just as well he didn't allow the newfound lack of inhibition to run riot, for at that moment a gentle yet urgent whirring sound filled the air. Stepping off the path at the last moment, he felt a whoosh as a muscled and tanned guy, clad in lycra and sporting a baseball hat, flashed by on a mountain bike.
10 seconds later, a second bike passed. This time the rider was female. Struggling to keep up with her male cycle buddy, the girl's cute backside was raised as she stood down hard on the pedals in flip-flops, puffing and panting as the forest floor stifled her progress like it was made of treacle.
Stopping up ahead to wipe a forearm across a moistened brow, she turned briefly to glance at Matthew, offering a half-smile through the pain. Her breasts that heaved at a cream coloured tank top looked like they craved to be squeezed. Before there was time to return the compliment, however, she was gone, her arse bobbling seductively.
The peace restored, Matthew's only companions in the forest during a mile-long stroll were the birds that hid furtively in the trees, the squirrels that slid smoothly through the undergrowth like creepers and the watchful crickets keeping time like a metronome. Reaching a clearing, Matthew contemplated getting back to the house. Yet he was drawn by a sixth sense down an almost hidden path that would take him even farther away from his destination. Glancing down, he noted its dusty surface scored by two thin tyre tracks.
Following the trail for another mile, once more the distant sound of water rippling was audible. It was then that the tyre trail ended, two bikes hastily discarded on their sides a few feet away. His eyebrows elevated at the discovery of a discarded white Adidas trainer, then another a few feet on. Next was a balled-up black sock, then another. Continuing in some Hansel and Gretel-style trail, the breadcrumbs substituted for items of clothing, Matthew encountered a pair of flip-flops, then a lime green lycra top, shorts and a baseball cap. More intriguingly, he discovered a ruffled-up tank top, accompanied by a throbbing feeling between his legs.
It became even more intense upon spying what could only be described as the Holy Grail: a skimpy bra and thong set in matching lilac. Reaching down, Matthew caught hold of the thong, bringing the crotch to his nose and breathing in deeply. It reeked of intoxicating pussy juice. A more subtle aroma than the stench that seemed to be ingrained in his fingers for days after playing with Mae-Lin, Matthew felt his entire body quake with desire. This was young female in her sexual prime.
Slowing, he tiptoed towards another clump of trees, through which the stream down below swelled into a wide bowl like a private swimming pool. Able to creep closer, tree by tree, he heard voices, breath held tight. Visible from the waist up, the couple frolicked in the stream. Mesmerised, Matthew couldn't take his eyes off the girl's breasts, big and bouncy with droplets of water clinging to the expanse of flesh. A sight to behold – only the second naked woman he'd ever set eyes upon – Matthew had to shift position to attain comfort, the throbbing in his groin an unwelcome distraction.
But things would get better, much better. Without warning the boyfriend ducked down, disappearing beneath the black marble surface. The scene before Matthew lapsed into freeze-frame as suddenly the girl squealed, her legs taken from beneath her. Riding momentarily on the guy's strong shoulders, a squeal rang out as she was bucked clear, flashing the briefest snatch of pubic hair before she hit the water. Yet despite its ephemeral nature, the image of that pretty pussy was imprinted on Matthew's brain like a lingering filament.
Surfacing, the girl shot a look that was stern yet playful. The pair grappled, sinking below the surface before emerging in a heated embrace. Their lips smacked purposefully before tongues made exploratory manoeuvres within. Matthew found himself rooted to the spot, a hand brushing across his crotch, guiltily appraising the semi-hardness. He was sorely tempted to masturbate, such was the effect the couple were having on him.
Just as well he didn't follow his urge, for at that moment Matthew discovered he and the couple were no longer alone in their reverie. "They sent me to find you," clarified Meg, causing her younger brother's face to turn a spectral white and perspire profusely as his eyes darted from Meg to the lovers like a spectator at a tennis match. "Did you, um, want to be alone?"
More terrified of discovery by the couple than of discovery by Beth of his guilty secret, Matthew pursed his lips and placed an upright finger to them, craving quiet. Easing up close to see what held his attention so raptly, Meg gasped hoarsely. "Matthew!"
"Shush," he said, arms flapping.
They exchanged furtive glances before Meg moved in front to gain a more favourable pitch. In doing so, his eldest sister's arse brushed the partial erection, thankfully enclosed behind suit trousers and boxers yet nonetheless causing Matthew to staunch a groan. A cheeky glance up and aside as the shaft slotted cosily in the groove, Meg relaxed into her long lost brother's big strong chest. Chin dipping to rest upon her crown, Matthew towered over the girl, fixing his gaze once more on the courting couple, hands hanging redundantly by his sides.
He could feel his heartbeat thumping into Meg's shoulder as the couple up ahead petted furiously. Growing tired of the water, the guy lifted the girl into his arms and climbed from the stream, dripping wet. Meg pushed back as if scared they might be discovered, yet Matthew remained rooted, the sudden movement rubbing his foreskin as it fitted ever more snugly into the accommodating groove.
The lovers moved to within twenty paces, blissfully ignorant of their audience. Unashamedly exposed to the elements, they seemed unfazed by a slight chill in the air, illustrated on the girl's erectile nipples. Matthew could hardly take his eyes off them, except to gaze down longingly at the gorgeous and smoothly shaven pussy in matching pink. At the same time, Meg's eyes were fixed firmly to a thick cock that swung impressively between the guy's legs.
As Matthew's hands hung idly, Meg moved hers behind to rub his buttocks. Forgetting they were brother and sister, instinctively Matthew began to move his groin in time. Both could, however, be forgiven the dalliance for there'd barely been time for it to sink in properly that were brother and sister. Not that they were – in the conventional sense at least. Parted for two decades, there was no emotional bond between the pair, just a sprinkling of shared DNA. That and the fact they were two exceedingly horny twenty-somethings seemed to excuse their actions.
And it wasn't just Matthew. Meg purred as she moved her arse all over his stiffening cock, and that seemed to make things okay. She was as complicit as he.
Up in the clearing the guy had succeeded in working his cock up into a savage looking beast, sprouting proud in all its circumcised glory. The girl moved in stealthily on all fours like a prowling tigress, tongue running seductively around the inner circumference of her lips. Leaning back upon his elbows, chest inflated, the guy reached out for his girlfriend's hair, ensnaring a set of fingers in the brunette tangles and wrestling her face close to that outstanding appendage. Dipping her head, the girl smiled as her tongue tip touched his balls lightly before licking all the way up the rampant shaft. At the crest she licked the eye lovingly before enveloping the engorged head with a succulent mouth.
Matthew felt Meg's body tense against his and her breath begin to quicken, a guilt-ridden glance his way before settling back down on his cock and rolling it between her arse cheeks like a hotdog in a bun. If Matthew closed his eyes, he could envisage the act minus the layers of clothing that prevented the hard cock splitting the petals of her soft moist pussy. Meg felt it too, clamping her thighs tight to rub her aroused cunt lips together.
Hands still hanging idly by his sides, Matthew felt the overwhelming urge to feel her tits. Yet he hesitated, wracked by doubt. As if to prompt some action, Meg arched her back and pushed out her delightfully pert chest like a rooster. A pair of thick nipples strained at the front of the light blouse and threatened to pop the buttons. The outline of a lacy half cup bra beneath the blouse sent Matthew crazy with desire and, shaking like an arthritic, his hands elevated. It was as if suddenly he'd been possessed and nothing could stop it from happening. As Meg held her breath in heightened anticipation Matthew's palms covered the soft orbs, fingers reflexing.
The effect on Meg was startling, eliciting an audible breathy squeal that very nearly gave them away. Yet the couple were so engrossed in their own lustful games that it went unchecked. Adjusting, Matthew ran his thumbs around each teat, tracing small circles. Scared of what she might unleash, Meg's front teeth embedded firmly in the bottom lip, eyes screwed tight as the feeling between her thighs liquefied.
Up ahead, the guy had arrived at the throes of ecstasy, the girl anxious to join him. Running a hand down her spine and backside, she plunged two fingers deep into her gaping cunt as she continued to deepthroat her boyfriend with vigour. Sucking and licking, she frigged her pussy wildly, inducing an intense orgasm and a light spray from her cunt that hung momentarily in the air like a sprinkle of perfume. Simultaneously the guy began to exhale, his face contorting like he'd stood on a wasp.
The girl felt the first telltale jerk, tossing back her head and finishing him off with a blurring fist. Cum ejected like foam from a fire hose, looping in the air and peppering the girl's face and tits. She kept labouring away until every last drop had been drained and the once impressive cock melted in her hand.
