Grandad Billy

"What if I get pregnant?" Lucy asks Jason, wanting to know his attitude towards the supposed possibility, will he let his desires get in the way of common sense, although as far as he knows the chance is tiny, it could happen.

It's a sunny saturday morning and the couple have just made plans for Jason to make himself scarce that morning, sitting on the bed talking in whispers, Lucy's question suddenly throws a frown across Jason's fervent expression.

Jason regards her with suspicious eyes, "Why would that happen?...you're on the pill aren't you?"

Nodding, Lucy then points out that the pill is not 100 percent effective, not only is she wanting his attitude on the matter, Lucy is also getting Jason ready for the almost certain outcome of this rather strange and twisted 'affair'.

As expected, her young hubby is willing to throw caution to the wind, citing that the pill has worked all this time and that she shouldn't worry, little realising Lucy hasn't been on the pill for many months, and the real reason she hasn't conceived yet is that he is infertile.

On hearing Jason's stance on the subject, Lucy cannot help feel a surge of arousal from deep within, there is something so delightfully twisted about tricking him like this, and using Billy for her own ends, neither of them aware of what she's up to.

With the matter closed by an oblivious hubby, the pair put their plan into action.

Once back in the lounge where Billy is watching an old re-run of batman on tv, quietly chuckling at the dynamic duo's antics, Jason announces he's going for a long run and will be about an hour, while Lucy gets comfy in the dining area, sat at kitchen table with a book.

Both her and Billy say their goodbyes to him as he leaves, Jason briefly making eye contact with his wife before closing the door, their gaze meeting in electric anticipation.

As soon as the door closes Lucy feels it straight away, nervous excitement welling up from within. Being alone with Billy had always been a little nerve wracking in the past, but now there was an expectant thrill to keep it company.

For the next 5 minutes there's a tense atmosphere as she waits for the old fella to make his move. Those 5 minutes drag by, and every second Lucy expects him to approach her but he doesn't.

Billy waits while the show goes off, giving Jason time to get away from the van. From where they are there's a good view of the fields, clifftops and sea beyond, Billy gets up off the lounge seating and reaches for his binoculars.

Upon hearing him move, Lucy glances away from her book to see Billy peering through the binos, scanning the path that leads away from camp.

"Ah there you are." Billy says, quite casually to himself.

Looking back, she sees him focusing in for a clearer view, "That's him alright...there's my boy...off you go lad and have a good run...while I take care of our girl."

After saying this Billy lowers the binos and turns to offer young Lucy a lascivious grin, "Well...it seems we're all alone again princess."

What happens next happens fast, Billy places the binos down then moves quickly and with purpose, striding up to where Lucy is seated, grasping her by the arm and pulling her to her feet.

"Billy!..wait...he might come back...what if he comes back." Lucy protests, staying in her 'innocent' role.

Billy doesn't reply, continuing to pull her towards the back of the caravan, locking the van door as they go. Leading her to the small bedroom he closes the door behind them and orders young Lucy to her knees before him.

Lucy obeys, getting down on her knees as Billy is unzipping his trousers fly, again she keeps up the innocent role, expressing reluctance, "Billy...I don't think we should be doing this...yesterday...it was a moment of madn..."

Billy interrupts, gazing fervently down at her while replying, "Don't call me Billy while we're messing around...I'm grandpa to you now understood?...and grandpa's gunna fuck you real soon princess...but first your gunna wake my pecker up."

Lucy gives in, after all, she doesn't want to protest too much, and besides, she finds calling him grandpa...very kinky.

"Yes grandpa." She replies, gazing up at him with the most innocent expression she can muster.

His grin broadens, "Yeah that's right..." at this point, Billy's semi erect cock is freed as he undoes his trousers and pulls both them and underpants down, presenting himself to her, "...I'm your naughty...sneaky old grandpa and I've got something for you...here you are princess...you know what to do with it."

Lucy, without further ado, takes him into her mouth amid approving words and moans from above.

She explores gently at first, rolling her tongue around the head, feeling him get bigger. Although enjoying giving oral in the past with Jason, with Billy it's so much more exciting. Apart from him being more well endowed than hubby, the old man is so different physically, the taste, smell, amount of hair, all contrast with Jason.

Having never strayed before, Lucy revels in the experience of being intimate with another man, the fact that Jason knows full well what his wife is up to, making it all the more special.

She soon has old Billy nice and hard, and he asks her to withdraw and take her clothes off. This doesn't take long as she's only wearing a summer dress and panties, white ankle socks. Having gotten used to being bra less in the van for Billy's benefit it's now Lucy's second nature, doing it without thinking.

While undressing, Billy, who's also taking his clothes off, asks her to leave the socks on, giving lucy a cheeky wink while removing his shirt. She obeys the request leaving them alone, and now finished, stands in just her socks with hands behind back waiting with a burning anticipation, for Billy's next move.

She can feel that she's already moist between the legs, can see the damp patch in her panties on the floor, as can Billy, who eyes the soiled garment with a grin as befitting a dirty old man.

"I see you're ready for grandpa princess." Billy comments, then alters his gaze to the small amount of neatly trimmed fair hair nestled within Lucy's crotch, "And you're a natural...I often wondered about that."

Moving to one of the single beds, his large cock wobbling to and thro with each step, he lays flat on his back and indicates for Lucy to approach.

"Turn around so you're facing away...that's right...now get on top of me." Lucy obeys, getting down on top of the bed, and Billy, in a 69 pose.

"Yeah that's good...now bring that cunny up here for grandpa...yeah...keep going...oh yeah I can smell you baby...mmmm."

Lucy lowers her groin down onto the old fella's face and quietly gasps at the touch of his tongue, the prickle of stuble tickling.

He gives her a few licks, sliding his tongue beneath slick lips...a glorious first taste.

These initial exploratory lashes soon turn into a burst of greed, as Billy relishes the scent and taste of the young lady, "Oh...ah...oh yeah."

Lucy's words are interspersed with gasps, she's so surprised by the greedy way in which Billy is devouring her, the thought of licking him back doesn't initially occur.

She kneels, legs splayed either side of Billy's head, eyes closed, enjoying the experience...

Meanwhile, on the clifftop pathway, Jason has had to give up on running, at least for a little while.

Now sitting on one of the many benches that dot the clifftops facing out to sea, it was difficult to run with a hard-on, not physically as such but more the risk of embarrassment. Moments earlier Jason had been surprised by happening upon an old woman out walking her dog, oh the look on the old lady's face when her gaze settled upon the very noticeable bulge in his shorts...

Her cheerful expression as she was about to greet the handsome, tall young man running towards her, had rapidly changed to one that could only be described as moderate peril.

The incident would perhaps have appeared comical to Jason at any other time, but this was different.

After all these years of becoming aroused by Billy's interest in his sweet young wife, he was now finally living out his wildest fantasy.

Thoughts and images of what would be going on back at the van flooded his mind and it was all he could do to resist masturbating right there on the bench, having looked about himself several times already to see if anyone was nearby, he'd only abandoned the idea due to a small fishing boat gathering up nets close in to shore, they may just be able to see what he was doing.

Still the lust within him grew to a point where it was almost overwhelming, this, this was so special, and not just for the fact that Billy was probably fucking Lucy right at that moment, there was something else which gave it that extra kinky 'kick'...something he was keeping secret from his wife...

Back at the van, soft moans are just audible to anyone walking close by the back of the caravan. Inside, Lucy, having almost climaxed in Billy's mouth, on his orders has changed position, now impaled on the old fella's large appendage she's vigorously riding him, while Billy has turned his attention to her ample rack, sucking each tender young nipple in turn, as he toys with and twists the other between thumb and forefinger.

Lucy has never felt so full, and despite being soaked from the licking Billy gave her, she'd slowly, almost gingerly sat down upon him, feeling the monster stretch her opening and insides.

But she's quickly gotten used to his size and is now working up to the climax previously denied her by 'grandpa', who'd expressed a desire to see her face when she came...he was about to get what he wanted.

Lucy bucks her hips ever faster, pulling up away from the old man's greedy affections, he lets her go, sensing what's coming.

Gazing gleefully up into her eyes as she closes hers, face contorting in a silent scream, head thrown back, Lucy goes still and Billy feels her little pulses on his hard cock as she spills over him in a small gush, he feels her trembling, juices running over his balls.

"Yeah that a girl...oh princess...grandpa's very pleased with you." Billy's words are spoken quietly and in sleazy tone, Lucy only vaguely conscious of what he's saying, her mind awash with intense pleasure.

Slowly coming out of it, she lowers her head, rapid breath slowing down, eyes opening to find Billy's smug grin awaiting.

"Well?...what do you say?"

Through the haze of her climax Lucy instinctively knows what Billy wants to hear, beginning to grin herself, she replies quietly, "Thank you grandpa."

His grin broadens before he acknowledges, "That's my princess."

There now follows a brief but very intimate moment between this odd couple as Lucy explores Billy's cock inside of her. When first inserted, it had all been about adjusting to his larger size and then once that was achieved Lucy went for it, wasting little time in chasing the climax that had previously eluded her, springing up and down on Billy's hard-on for all she was worth.

But now she enjoys toying with him, gently squeezing, moving up and down a little, feeling his thick girth sliding in and out, the head bumping her on deep in-strokes.

Billy watches, content at least for a moment to watch and feel her playing, see the satisfaction in her eyes joined by wonder.

A slick, sticky noise comes from between them as Lucy slowly, teasingly, milks Billy's old cock.

"Mmmmm...oh you are a naughty girl...teasing me like this." He says, feeling her squeezing him.

With some composure regained Lucy shows Billy a sexy smile, then lowers herself to him for a deep sensual kiss. Tongues dance together while Billy takes over control of the movement, beginning to slowly thrust upwards into her.

What tips him over the edge, triggering his dominance, is when Lucy gives out a nasal moan through their kiss.

Being teased was provocative enough but hearing her sexy noise prompts Billy to action.

He breaks the kiss, pushing her back away from him, pulling out and beginning to get up, Lucy's initial look of nervous surprise turns to thrill as she quickly realises what's happening.

The couple briefly part, Billy ordering Lucy onto all fours, she immediately obeys, feeling a surge of excitement welling up from deep within...this is it.

What she'd initially rejected when first suggested by Pat, which seemed like decades ago, but had reconsidered with surprising results, what she'd planned for and enjoyed toying with both men for was going to happen now, she was about to be bred by her husband's real dad.

A sense of urgency laced with the most exquisite anticipation fills the little bedroom, the bed creaks and squeaks as big old Billy gets into position behind her. Lucy's fingers clutch at the bed covers in readiness, and she aims a quick glance back to see the hulking form of Billy, looming over her.

He grasps hold of her hip with one hand while guiding himself in with the other, ramming it home in one swift movement that elicits a loud gasp from Lucy.

Then...pain and noise explode together, a hard slap on her rear causing Lucy's face to contort, her mouth to open wide. She'd been lightly spanked before by Jason and enjoyed it, but this was very different.

Slap...slap...slap on the same cheek smarts so much it causes Lucy's eyes to water. Suddenly she feels Billy's big hand gathering up her hair and her head is yanked backwards hard, she feels his hairy chest on her back as he lowers himself down, then a quiet but confident voice in her ear, "You've been a naughty girl...teasing me...haven't you princess?"

She answers immediately, out of the worry that to not be prompt may result in more hard spanking, "Yes grandpa."

But it's to no avail, Billy raises back up and swaps hands, now tightly pulling her hair with right hand his left comes down hard several more times in quick succession on Lucy's other cheek, the pain causing her to yelp.

"Yeah that's it...you squeal." Billy chuckles to himself before continuing, "I like to be teased young lady...but you've made an art out of it this past week...and you have to know sweetheart...that you can go too far...I bet my lad doesn't discipline you like this does he?"

Not waiting for a reply, Billy continues with another round of spanking, the pain mixing with the pleasure resulting in a surprisingly exhilarating sensation for young Lucy.

Waiting while he stops once more, she answers in a small, breathless voice, "Oh god no...no grandpa...he doesn't."

Initially shocked at Billy's behaviour, and with the pain, the administration of harsh punishment has stimulated her submissive nature in an exciting new way, leaving her actually wanting more. However, Billy has decided that she has learnt her lesson for now, and discontinues the spanking.

"Yes I could tell...but from now on if you're a naughty girl Lucy... you will be dealt with swiftly and firmly understood?"

Lucy responds once more with haste, "Yes grandpa...I understand."

Billy lets go her hair, gazing down at Lucy's beautifully rounded, peachy rump, the cheeks a rosy red due to his recent handiwork, he admires the view for a brief moment while praising the young lady for her compliance, then tells her something that's music to her ears and sets her heart racing.

"Now...we probably don't have much time left...get your head down...on the pillow..." While speaking Billy places a hand on the back of Lucy's neck pushing her down hard, "...that's it...stay like that...I'm gunna spunk you now... spunk you good...oh yeah...fuckin ell you're tight."

As Billy is saying the last part he's beginning to thrust, working up a healthy rhythm, the slick, sticky noise returns, as does the creak and squeak of bed and mattress.

Lucy closes her eyes, pleasure taking over from it's neck and neck race with pain, pulling ahead, eliciting moans and gasps from her that spur Billy onwards. Grasping Lucy's hips tightly, he can feel his old balls beginning to boil, thrusting ever faster, the snug grip that her young cunny is offering pushing him quickly to the point of no return.

Lucy too, can feel Billy's impending climax, his big cock is buried so deeply on the in-stroke that he's bumping her every time.

Bizarrely, as Billy begins to curse and pant, advising his 'princess' that he's almost there, it suddenly occurs to Lucy that this position, doggy style, is one of the best for conception, allowing for deep penetration and the deposit of sperm close to the cervix.

It's a piece of very relevant information, the knowledge of which stirs up a level of arousal Lucy has never experienced before, knowing she's in a prone position with a fertile partner...and that partner being her own father in law...

At that moment Billy pushes into her deep and hard, going still and taut, his buttocks clenched tightly together, his grip on Lucy's hips beginning to cause pain, "Aaahh...aaagh...ahhhh...yes!...fuck me."

She feels him twitching deep inside her, and it's this sensation that pushes lucy into a second orgasm, the resulting scream of delight muffled somewhat by the pillow into which her face is burrowed.

There follows a moment of gasping and panting, no more commentary from Billy just silence, save for heavy breathing while this odd pair of lovers enjoy the intense sensations flooding both their minds.

It's another special moment between Billy and Lucy, an important part of the bonding process for this fledgling, passionate affair.

Billy is the first to move and speak, relaxing his grip on her hips, lowering himself over Lucy's back and planting several tender kisses on the back of her neck while his wandering hands caress her belly, moving slowly upwards to heaving bosoms, their nips standing erect, hard to the touch.

"Mmmm...oh princess...you got grandpa wet again...good girl." Billy can feel her juices dripping off his balls.

Lifting back up off her, his breathing now under control, Billy slowly pulls out, gazing eagerly down as his glistening cock slides out her neat little pink slit, the stretched skin of which forms an almost perfect 'o' around his girth.

His spent member flops out with a 'Schlock' sound, followed by more of her juices and some of his cum. Billy watches the mixture slide down Lucy's inner right thigh.

He gives out a little chuckle, "But this time grandpa got you wet too...oh yeah...spunked you good...not much to see back here...so most of it must still be inside..." Here the young lady receives another slap on the rump, this one lighter, playful.

"...you'd better get cleaned up before Jase comes back...don't want him seeing you in this condition now do we?"

Lucy begins to move, turning over and laying with her back propped against the bedroom wall, she gazes down between her open legs to see matted pubic hair and wet patches on the bed sheet.

Gazing with fascination at Billy's shrinking, wet cock, she notes a large droplet of cum welling up at the tip then dripping onto the cover below.

It appears that old Billy really has 'spunked her good'.

Placing a hand down between her legs she can feel the mixture of her own juices and Billy's cum leaking out, the smell of it lies heavy in the air.

"Right my girl..." Billy's words almost startle her from preoccupation, "...get your head down here and lick grandpa clean...then you can go get showered."

Lucy obeys, getting onto her side then licking Billy's soggy cock and balls clean.

He strokes her head and hair as before, praising her and assuring he'll keep what they're doing a secret. Once the old fella is pleased Lucy has done enough he gets up off the bed and begins dressing.

After such an intense session Lucy is still in awe, in contrast to Billy who seems unfazed by the experience and ready to get on with something 'normal'.

Lucy puts it down to him being more experienced than her when it comes to sex, and certainly so with the little matter of cheating. She'd at least thought he'd be more concerned and cautious about doing it with his grandson's wife but no, cool as a cucmber...curious.
