Grandpa's Pet

Summary:

Rebecca is supposed to go to Summer school, but she'd rather enjoy her vacation. Her grandfather Samson agrees to let her skip class on the condition that she act as a housepet.

Notes:

Thanks everyone for over 11 million hits on the stories altogether and over 1 million on Uncharted Waters. Unfortunately, I can't brag about it to anyone, because it'd mean explaining the kind of story I post on this account. Still fun.

Chapter Text

Rebecca sighed, drew back the end weight on the Newton's Cradle, and watched the balls flick back and forth. It was sunny outside, and the house had a pool. She loved swimming, she loved tanning. But she was in a rut. The prospect of returning to Summer school the next morning really had her down.

She knew it was fair. She'd have to redo her final year of high school, and even though she'd received an ADHD diagnosis that explained a lot of her struggles, and a corresponding pharmacological regimen, she understood why her parents insisted on additional classes.

That didn't mean she had to like it.

‘Hey, kitty.’ Rebecca looked up. Her grandfather had walked in from the garden, where he'd been reading and soaking up the sun in shorts and a t-shirt. He lifted his sunglasses onto his head, his kind eyes crinkled with concern. ‘You don't feel like going for a swim? It's gorgeous out there.’

‘I'm okay,’ Becca replied, plopping her chin down on her crossed forearms.

‘You don't sound okay,’ Samson said, leaning against the wall.

‘Yeah. I guess.’ She lay turned her head to the side to look at him, radiating gloom. ‘I dunno. I'm just kinda sick of Summer school… you don't wanna be the best grandpa ever and let me stay in tomorrow, do you?’

‘Are you saying I'm not already the best grandpa ever?’ He walked past her, affectionately running a hand through her hair on his way to the couch. Rebecca's parents and sister were on a vacation cruise to the Bahamas, and that made her own decidedly garbage summer sting all the more. She loved her grandfather and always had fun visiting him at his secluded home, but she'd hoped to spend her 18th summer sipping cocktails on international waters. She was ruminating on this thought when Samson sat down with a sigh, shorts tugging up his strong thighs –

Her eyes widened when his thick, soft cock popped out of the leg hole and onto the couch cushion.

Samson had always been an avid hiker and biker, and he still did all the gardening and upkeep around the house. Rebecca knew he had a good body for any age, let alone his late sixties, and as she'd grown and gone through puberty, she'd often felt a secret flutter in her chest when he put his muscular arms around her for a hug. She'd never really paid attention to his bulge, though she'd frequently seen him sunbathing in trunks, and she'd never imagined what lay underneath.

Despite his age, he was uncut, thanks to his first-gen European migrant father being unconvinced by the American preference for infant circumcision. Judging by the way it bounced when he sat, his cock seemed weighty, the covered glans resting low on a pair of smooth, heavy balls a couple of shades darker and rosier than his body. At the tip, the opening in his relaxed foreskin was wide enough to show a tiny glimpse of his shiny, pinkish-purple head, and the lips of his piss slit.

It was the first real-life dick and balls she'd ever seen, and she instinctively felt an urge to touch them, to feel the texture of that delicate skin and know the reality of what she’d seen in porn.

Flustered, she quickly looked away. Despite the amount of detail she’d observed of his manhood, she’d only been staring for a couple of seconds at most. Still, as her gaze swept up his body, she thought she met his eyes.

Did that mean he’d seen her looking? She hoped not. Nervous, she watched the world through the window and waited for him to continue.

‘Look,’ came Samson's voice, tone soft. ‘Show me your notebook.’

Becca’s attention snapped back to him, eyebrows raised, and she darted over to her discarded backpack to fish out her recent schoolwork. Samson plucked his glasses from his t-shirt collar and put them on to scan the documents while his granddaughter stood by, anxious. She’d been doing well, but she wasn’t sure what he was looking for, and his poker face was firmly in place while he leafed through her writing. Finally, he set the papers on the coffee table and crossed his arms, gaze still lowered. ‘You’re more than keeping up. I thought that was the case anyway, with how fast and how well you’ve been finishing your homework, but now I really know.’

‘And?’

‘I can’t let my granddaughter stay home from school for no reason, Bec. You know that.’ Rebecca took in a deep breath, ready to sigh and tell him she understood, but he quickly continued: ‘Now… a pet could stay home as long as it wanted.’

The teen’s lips parted in confusion. Samson continued: ‘You know I’ve only ever had indoor cats, right, kitty? Pity you aren't one of them, at least for the week. Though… I always told you you could become anything you put your mind to.’

He winked. The rest of the day was spent mulling his words over. When she was little, she went through a phase where she'd act like a cat when visiting her grandfather's home, crawling around on all fours, meowing. She wanted a pet at home, and with her parents not allowing it, there was something fun about trying to relate to her grandpa's pets, particularly with how willing he was to play along. He'd put her snacks on a little plate on the ground, wave a toy wand, pet her belly. It was fun. 

Was that what he was suggesting?

That certainly seemed to be the case based on Samson's comment later that evening, when they were clearing dishes after dinner. They tended to keep to themselves in the late evening, and before they parted, he smiled at her and said, ‘Hope I'll see an old cat buddy tomorrow. You never know.’

Laying in bed, Rebecca mulled the idea over. It was such a bizarre proposal, but her grandfather has always been playful and a little off the wall. If anything, it was probably an attempt at psyching her out: with the alternative being this weird pet concept, surely she’d pick going to school. As she fell asleep, she thought that, yeah, maybe classes weren’t that bad.

When she woke up the following morning to a blaring alarm, the beginnings of a gorgeous sunny day, and a full day of work to look forward to, she reconsidered.

She sat up in bed and stared at her backpack for long, silent minutes. It contained her notebook, her homework, her pencil case, an apple, and her refillable water bottle. Nothing too heavy, but the thought of putting it on her shoulders felt like having to carry a horse. Slowly, without thinking about it too much, she stepped out from under the covers and positioned herself on her hands and knees on the carpeted floor.

It felt awkward, obviously. She didn’t make a habit of wandering around on all fours, and she couldn’t really remember doing it at all since she was about nine or ten. Still, as she experimentally crawled around her grandpa’s guest bedroom – which she’d commandeered for the summer by moving in her plush toys, expansive makeup collection, and posters of Chappell Roan and Sabrina Carpenter – she got back into the swing of it surprisingly quickly. As long as she kept to the carpets and mostly loafed on the couch, she could manage without hurting her knees. Honestly, the most annoying part was the way her pajama bottoms stretched taut and tight across her cute, firm ass, restricting her range of motion.

She paused, and sat on her haunches. It was going to be a hot day, with an average of 90 degrees. What if she just… spent the day in her underwear and a tank top? When they played pets, a decade ago, she was often in her swimsuit or short shorts and a t-shirt. It had to be okay now, too. He was her grandfather , practically a second dad. It wasn’t inappropriate.

She wiggled out of her pants, and traded her sleep crop for a baggy tank top, not bothering with a bra since she didn’t intend on going out. She moved back onto her hands and knees, and caught a glimpse of herself in the mirror: a pretty girl, with the fullness of adulthood in the lovely curves of her butt and breasts, her long, smooth legs on display up to a high swimsuit cut, flashes of her belly when she moved, presenting like a bitch with her ass up.

Her grandpa wouldn’t think of her like that. No way. Plus, she only had to play along for a little while. If she gave up in about an hour, she’d be too late to show up to school. It was fine. She wasn’t sure why she was blushing, or why her heart was thumping, or why the image of Samson’s thick flaccid dick flashed through her mind, but she feigned confidence, nudged open the bedroom door, and crept out.

Thankfully, her room was on the first floor, so she didn’t have to navigate the stairs up to where her grandpa’s room and office were. She went directly to the living room, which connected to the open plan kitchen where Samson stood at the counter, in a t-shirt and shorts that showed off his muscular arms and legs, adding chopped strawberries to two bowls of cornflakes.

He heard her shuffle in, and turned around with a sleepy smile, eyes widening when he saw his granddaughter crawling on the floor. For a second, Rebecca thought she’d made a mortifying mistake, totally misread the signs, and that she’d have to jump up and play it off as a joke. He acted first, however, and crouched down with a hand extended toward her. ‘Hey, kitty! I haven’t seen you in so long!’

Relieved, Becca crawled over with a small smile, conscious of the hard kitchen floorboards on her knees, but wanting to play along. She got close enough to rub her cheek against his blunt fingertips, and made a sound of pleasure close to a purr when he ran his fingers through her hair, gently raking his clipped nails over her scalp, then down her back, over the fabric of her top. His touch left a fuzzy feeling of warmth in its wake, which seemed to seep into Rebecca’s veins and pool into her stomach to relax her. She didn’t think about how odd this scene looked from an outside perspective; she just let her rational thoughts go and enjoyed the affection, sighing and leaning her head against his chest while he caressed her back with his big, strong hand.

‘Alright,’ Samson said, and his granddaughter physically felt the rumble of his deep voice in his powerful chest, commanding yet soothing. She looked up at him, cheek still pressed against his pecs, and he met her gaze fondly, face disarmingly close to hers. ‘You can climb on the chair, right? I’ll get you something to eat.’

She missed the warmth and solidity of his body when he stood up, but the absence also made her self-awareness come back, and she was a little embarrassed about how much she’d enjoyed the brief cuddle with him. Was she really that starved for attention? She got onto the chair at the kitchen table, trying not to dwell on her concern, and sat with her knees at her chest, hands on the table like in pictures of pets “sitting like people.” Samson put the bowl of cereal down in front of her, and took the opposite seat to start spooning his breakfast into his mouth.

Becca couldn’t help noticing he hadn’t given her a spoon.

When she was little and they were playing pets, she’d eat cookies and drink milk out of dishes her grandpa laid out, but she’d somehow expected things to be different now she was grown. She looked at him uncertainly, but he wasn’t even keeping an eye on her, calmly eating his food as though it were any other day. She’d committed to this little game, at least for a few hours, and giving up this early meant she still had plenty of time to be shipped off to class. 

Hesitantly, she lowered her head and grabbed a strawberry slice with her plump lips, sucking it in to chew it. Then, she scooped some cornflakes and milk into her mouth with her tongue, and soon, she was eating and drinking from the bowl surprisingly easily, not even making a mess. When she was running her cute pink tongue around the bottom of the dish to scoop up the last drops of sugared milk, she heard chair legs scrape across the floor, and felt that familiar strong hand card through her hair again.

‘Good girl,’ he murmured, before taking the bowl to the sink. The words squeezed Rebecca’s heart, and for the second time in minutes, she wondered if she really was in dire need of positive feedback, if such mild recognition made her this pleased. The concern overshadowed another sensation, which was far harder to explain, that fuzzy warmth she’d felt in her scalp and back migrating south to make her pussy lips and little clit hot and sensitive.

It was hard to ignore the recurring tingle in her nether regions throughout the day. She lounged around the living room, watching TV – Samson left Netflix on with the show she was binging running – and walked like a regular person when she was in the bathroom, but there were peaks of sensuality between the normalcy. He’d stroke her head, side, and back when he wandered down from his office for a coffee, palm gliding over her warm skin when it touched her side, where her top had ridden up, sliding over the smooth expanse of her thigh. When she crawled a longer distance to follow her grandpa into the garden, she felt her panties dig into the cleft of her cunt lips, and though it was pretty uncomfortable, it also created a tight pressure on her clit and rubbed against it hard when she took a big step, which was happening frequently while she picked her way over the grass. By the time she was at his side, enjoying the ambient warmth while protected from the sun by the trees shading the pool, she could feel the fabric stuck between her plump lips, kept in place by the sticky slick starting to drool from her fuckhole.

Samson took a thin, waterproof mattress from one of the lounge chairs, tossed it onto the ground beside his seat, then settled in to read a book. Rebecca crept onto the mattress and curled up on her side, careful to angle her crotch away from her grandfather. There was an occasional breeze, enough to refresh without being cold, and she shivered when it licked the wet halves of her pussy, cooling them down and heating them up at the same time, natural temperature play. 

She figured she'd stay there a little while, until she got bored, but the comforting presence of her grandfather nearby and the sounds of the water lapping at the sides of the pool relaxed her. It was nice and warm, and deceptively comfortable on the mattress. Before she knew it, she was waking up from a nap, and stretched her young body. The sun was still high in the sky, so she couldn't have slept long, but it did seem like at least an hour had gone by. Samson lowered his book and checked his watch.

‘School's out. Welcome back, Becks.’

Rebecca blinked, and got on her hands and knees, her sleepy brain slowly processing the words. School's out. Of course. She was only meant to be in pet mode during class hours. That meant she’d successfully enjoyed a whole day of her summer vacation, with fun and comfort. There were a couple of odd moments, some she’d even call sexually tense if they hadn't been interactions with her grandfather , but all that could be ironed out… if he let her repeat this trick the following day.

She’d been stuck in the same all-fours pose while she thought all this over, and finally looked up at Samson to ask him if the kitty could be a regular guest, at least for the rest of this week – and that’s when she saw him looking at her bare tits.

In her current position, her teenage breasts hung freely, unhampered by a bra or tight clothing. Her tank top was actually fairly modest when she was standing or sitting up, but now the scoop neck dangled open to give her grandfather a fantastic look down the front of her top. Beads of sweat shone on her smooth skin, eroticism on eroticism. Rebecca had been self-conscious about the slightly pointed shape of her boobs, because they were capped with dark, puffy nipples, softer than the rest of the breast and sensitive, too, likely to stiffen and poke out visibly through her tops. She practically felt Samson’s eyes palpating her little titties, and the jolt between her legs travelled up to the tip of each breast, signalling the nips to stand at attention.

Rebecca quickly turned around, trying not to show him how flustered she was while prioritizing making herself decent, and she was in such a hurry she forgot that all she was doing was displaying her ass to him instead, and more to the point, her cunt . She hadn’t pulled her underwear back into place, so the crotch remained firmly squished in between her labia, the pussy wedgie transforming her ordinary white panties into a provocative thong that bisected her sweet teenage slit and only covered up her clit, which had to be visibly twitching against the wet fabric. She awkwardly got to her feet, and swore she heard her grandpa grunt behind her.

‘I’m, uh, gonna go put my jammies on,’ she said, rotating her feet at the ankles to shake out the pins and needles. Moving her legs also had the effect of shifting her underwear back into a more respectable position, and she discreetly helped the process along by plucking the fabric out from between her buttocks.

‘Take it easy,’ she heard Samson say. His voice sounded casual, maybe a little too much. ‘I’ll finish a couple more chapters, then get started on dinner. I’ll call you down when the food’s ready.’

‘Sounds good.’ Becca started walking back to the house, the short grass warm under her bare feet after baking in the sun all day. Unable to resist, she cast the quickest, shortest glance back over her shoulder. She had a hunch she’d see something that would make her heart drop down to her pussy, and she was right.

Samson was wearing the same shorts he’d had on when she’d glimpsed his flaccid meat, and now, the escape hatch of his pants leg showed her even more. Her grandfather’s erection poked out of the left leg of his shorts, and it looked like a completely different organ from the hot but cuddly limp dick she’d seen. It was different in color, a bluish puce at the shiny glans with a gradient down to a shade darker than the rest of his skin, even more apparent in the way his penis rested on his paler thigh. Usually protected by his foreskin, his exposed cockhead and frenulum were visibly moist, the veins and thick underside ridge of his shaft highlighted in the sun. His balls were hidden, but pulled up higher, the crotch of his shorts pulled taut across his big cum tanks. He fidgeted in the chair, hurrying to tuck his rigid dick away, hiding it under his book.

Rebecca had looked back at just the right moment to see the effect she’d had on him, and the knowledge she’d turned her grandpa on carried her back to the house as if on a cloud. It should feel violating, repulsive, but all it did was make her cunt throb like crazy. She was in her room, laying on the covers of her bed, trying to wile away some time on social media, but every once in a while she’d remember the sight of his cock, the way she’d felt when he petted her and fed her from a bowl, and she’d have to squeeze her tights hard to make a flutter of pleasure go up her little clit to the pit of her stomach.

She didn’t have it in her to outright masturbate. Somehow, that felt a little too far. There seemed to be a real tension between them during this petplay episode, but she could have been imagining it. And his boner didn’t mean anything nefarious – she was pretty proud of her body and it was just a natural reaction to seeing a pretty young girl’s tits and ass.

It felt all the more surreal because she found that she didn’t really look at her grandfather differently. When she just thought about him – and not his old stiff dick – she just felt the same warm, familial fuzzies she always did when she thought of a beloved relative. When he called her down for dinner, she confirmed these sentiments.

Becca expected the meal to be a bit awkward, but it went by just like any other after-summer-school evening. Samson made roast potatoes and chicken, and they spoke about what was on the news for the first moments after they’d taken their seats at the table. Between forkfuls, he smiled at her, innocent. ‘And how was school today?’

‘Same as always,’ she replied without missing a beat. ‘Pretty boring. I bet you had a more interesting day than me.’

‘You could say that. I had an old friend stop over. A little kitty I hadn’t seen in almost a decade.’

Rebecca’s grin was genuine. ‘That’s great, grandpa. You think she’ll be back tomorrow?’

‘I think she might.’

That was the only real reference they made to the bizarre deal they’d struck, and Rebecca was just thrilled to be allowed to stay home the following day, too, even if it meant acting like a pet again. It was pretty easy, in all honesty, even kind of fun. She liked not having to think about things, not having to worry about her increasingly complicated life, with the tribulations of early adulthood. They chatted and enjoyed the food, washed the dishes together, and watched a couple of episodes of trash reality TV before Becks started to yawn.

‘Alright, I’m gonna go to bed,’ she sighed, hopping off the armchair. Samson remained on the couch, and waved as she walked past him towards the guest bedroom. She was almost out of the living room altogether when he spoke, somewhat haltingly:

‘Y’know, there was just one weird thing about the cat today.’

Rebecca paused, and turned back. He was still looking at the TV, acting as if he was just making an innocent comment. ‘What was it?’ she asked.

‘Somebody – I guess her actual owner or whoever – put a little outfit on her. Looked kinda constricting.’ He shrugged. ‘You know how it is. Even if it looks cute, pets shouldn’t wear clothes.’

Rebecca stood in place for a couple of beats, and made an affirmative noise before murmuring, ‘Goodnight, grandpa.’

There was no way she was easily getting to sleep after that. She lay in bed until late, alternating between doomscrolling on her phone and thinking about Samson’s words. It seemed stupid to ask what he meant, because it was pretty obvious, but she couldn’t figure out why . The only explanation –

No. It had to be him trying to psyche her out again. He’d been nice enough to let her skip a day of school, and he was too nice to outright tell her no. She’d had him wrapped around her finger since she was a kid, and he always caved. Making an extraordinary demand was his way of making her chicken out.

Well, she’d make sure it wasn’t going to work. She wouldn’t back down from a challenge, no matter how harebrained.

The following morning, standing in front of her mirror completely naked, she found it was easier to think that way than to actually go through with it. She had her arms by her sides, turning first one way, then another, trying to glimpse every angle of her tight young body. She often saw her nude reflection after a shower or while getting dressed, but observing herself like this, almost clinically – that felt strange. It made her hyper-aware of the smoothness of her freshly shaved legs, the teasing wisps of closely cropped pussy hair on her mons, the elegant way each curve flowed into another. Standing in profile, she half expected to be able to see her chest throb with each powerful heartbeat. Her mouth felt dry.

She was really about to do this. And she had to get a move on before she could talk herself out of it, so she did her best to clear her thoughts, focus on the relaxation ahead, and got on her hands and knees before nudging the door open and walking into the living room.

Being completely naked in the common areas of her grandpa’s house was a trip. She felt the soft carpet under her knees and palms as she crawled through, noting the slight jiggle of her breasts and cute puffy cuntlips with each decisive step forward. They’d spent so many evenings here as a family, playing board games, some of her grandfather’s old console games, watching movies, celebrating Christmas and New Year’s and birthdays… the walls had witnessed her at every stage in her development, from cradle to now, and in a weird way, she felt like she was paying the old home back by letting it feel and see her beautiful bare body. Moving among the ghosts of the past without clothes on was a thrill, and she bit her plump lower lip to stifle a groan as she made her way to the kitchen, where Samson stood facing away to ready their breakfasts, just as he had the previous day.

He must have heard her come in, but he didn’t turn towards her as she made her way into the room. Talking wasn’t on the cards, but there was no way she was going to meow or bark – even though it seemed absurd to have standards of decency given her current position, she couldn’t help the way she felt. She moved over to her grandfather instead and pawed at his bare leg, which still didn’t seem to get his attention. She saw that he was wearing earphones, humming a tune under his breath, and though she assumed he was just teasing her, maybe he really was distracted. Rebecca’s next move was to shift back on her knees, sitting up, and to press the front of her naked body against her grandpa’s leg and side, like a puppy clamoring for pets.

Samson looked down at her right away, smiled, and popped the headset out of his ears. ‘Hey, kitty, you’re back! And you’re all fun and fancy free today, huh?’

He reached down to pat her head, and Rebecca sighed happily as his fingers massaged her head. It helped her sink into a space of mindless comfort, which only made her more aware of physical sensations and, naturally, of the way her naked teen body slotted against her grandfather’s side: she leaned her face in the small divot just over his hip, his muscular thigh neatly parted her breasts, and if she tilted her hips forward, she could press her sensitive, tingling clit against the side of his shin. She could hump him like a dog and get some relief from the strange, mounting tension that had been building for two days.

Samson’s fingers left her scalp and he went to place the two bowls of cereal on the table, as always. Becks blushed, embarrassed she’d even considered rubbing her pussy on her grandpa’s bare leg – even though it wasn’t really her thinking that, it was some kind of subconscious free-floating thought. That’s what she told herself, anyway. The breakfast was a good distraction, and she found herself digging in without utensils straight away, now more experienced at eating this way without making a mess. When she looked up, licking milk off her lips, she saw that Samson was watching her with a fond grin, and without thinking, she made a happy, chirpy noise. Not a meow or a bark, but definitely something similar, a sort of pleased yip.

‘Glad you liked it,’ he said, with a chuckle. He took the dishes to the sink, then walked to the door and indicated the living room with his head. ‘I have some work to do today, but how about we watch a little TV together first? It’s still plenty early.’

Rebecca nodded and carefully made her way off the chair and to the floor to trot over to the comfy couch. She didn’t remember it ever not being there, and it was thoroughly broken in and softened to perfection, the most relaxing piece of furniture she could think of. The fabric still smelled faintly of tobacco, even though Samson had quit smoking around the time she was born, and that was oddly comforting, too. She hopped onto the cushions, and considered laying down on her front first, but having her ass on display without being able to see much seemed even more daunting than the other option, so she lay down on her back with her thighs pressed together, obscuring most of her vulva. Her young tits were on full display, of course, but there wasn’t much she could do about that except nervously run her hands over the soft, jiggling flesh, waiting for her grandfather’s move.

Based on the way he’d discreetly checked her out the previous day – and popped a rampant boner over what he’d seen – she figured he’d get his fill of her luscious breasts and the hint of her cute little pussy, and that she’d get to satiate her curiosity over the sight of a real-life erection again. Instead, Samson very casually took his place on the free side of the couch and turned the television on, navigating to the show they were making their way through while Rebecca was staying with him. He made eye contact with her, bypassing her naked body, and winked. ‘I’m supposed to be watching the episodes with my granddaughter, but what she doesn’t know won’t hurt her, right? I gotta know what happens.’

Becca rested her hands loosely on the mounds of her breasts and made an affirmative noise. Her heart had been beating almost painfully hard when she lay down, not out of fear of what might happen – she’d never feel threatened around her grandfather – but out of expectation. Of what, she wasn’t sure; maybe she wasn’t letting herself think of it, consciously. Anyway, her heart rate calmed down as they watched, and her nakedness became more of a non-issue. This felt a lot like their normal evenings together, and she was comfortable enough to kick her feet onto his lap at some point. He put his hand on one of her ankles and started lightly massaging it without taking his eyes off the television, digging his thumb and fingers into places she didn’t even know needed to be rubbed this way. It made her kind of boneless, and she let her eyes drift to semi-closed, not falling asleep, but settling into a liminal space of warmth and safety.

Samson’s skilled hands roamed from her feet to halfway up her thighs for the massage, and as she became more relaxed and less self-conscious, Rebecca’s hands fell off her tits to rest by her sides, and her thighs drifted apart just enough to expose the slit between her outer labia, the pages of her sex. In her sleepy, hazy state, she didn’t notice how much more of herself she was showing, how her nipples had firmed up and her slit plumped up and flushed with pleasure – or how her grandfather had started sneaking peeks at these hot spots on her body.

The episode of their TV show came to a close, and when the credits started to roll, Samson sighed and cleared his throat. The sound brought Becca back to reality, and she turned her head to look down herself and at him.

‘Wish I could stay longer, but duty calls,’ he said, with an apologetic smile. He took hold of her ankles to move her feet off his thighs, but she resisted, stiffening her legs to keep them in place and trap him. He laughed, and ran his hand from his granddaughter’s shin up to her thigh, higher than he’d touched before, but still chaste. ‘C’mon now. I have work to do, kitty.’

Playing up her disappointment, Rebecca withdrew her legs so he could stand, and stuck her bottom lip out in a little pout, which made him chuckle. He leaned over her, and despite the friendly nature of their conversation, part of her was struck by the way his strong frame loomed over her like this. It made her feel oddly small and defenseless, but in a way that heated up her insides.

‘Look,’ he said, ‘I like to take my time so I’m not stressed out, but I can get through these work-from-home tasks pretty fast if I want to. I’ll hurry to free up my schedule and we can play this afternoon. Sound good?’

Before she could respond, he bid her goodbye by ruffling her hair, then trailing his hand down the side of her neck, adding his other hand when he reached her clavicle. Flattening both sets of fingers and palms, he ran them either side of her chest to palpate just the outer edges of her breasts, then down her flat belly, gliding over smooth skin to the tops of her thighs, one hand over either of them. As they separated to stroke her legs, she felt his thumbs prod her mons, and touch the hard little root of her clit for a millisecond before leaving her body altogether. The whole affectionate stroke only lasted a moment, barely enough for her to register what had happened before he was walking up the stairs, leaving her flustered and tingling where his hands had touched her sensitive spots: the sides of her boobs, the swell of her pubis, and a particular buzz at the base of her clitoris that spread down the whole tiny button, leaving it stiff and poking out of its usual hiding spot at the top of her slit.

Was all of that on purpose? She thought about the touch on loop while she distractedly watched TV. Even though she lay on her front now, she could still feel her skin hot and tingling where Samson had stroked her. She wiggled to find a more comfortable position, and her breath stuttered when her pussy found the corner of a couch cushion. Slowly, she adjusted her legs, and rolled her hips in an initial, timid hump. Her clit pressed against the corner, and the motion of her thrust sent a wonderful tingle through her pussy, then another, building up the warm fuzziness of arousal between her legs. Her hard nipples rubbed against the cushion she lay on, and her face was half pressed against the fabric so she could inhale the scents she associated with joy and comfort, of this house and the man whose hard, tempting dick she’d seen, of –

of her grandfather!

The thought startled her, abruptly stopping the masturbation rhythm she’d been settling into. This wasn’t any different from actually frigging herself with her fingers; it was still weird and wrong. Reluctant and embarrassed, she climbed off the couch and ambled towards the doors to the garden, on all fours even though nobody was there to chastise her for walking. It was as sunny a day as ever, and she nudged the French doors open to enjoy the weather.

Soon, Rebecca sat on the seat her grandpa had occupied the previous day. The waterproof fabric of the mattress was warm under her skin, and she enjoyed the warmth as she stretched her beautiful body out fully, arms over her head. Her muscles seemed to sigh with relief, and being totally exposed to the warm rays of summer felt awesome. The yard was big, with tall walls made even taller by adjoining trees and vegetation, so she was pretty sure the few neighbors Samson had wouldn’t be able to see her naked body. Eyes closed, she wondered if it was a big deal even if they did. She loved her body, and she knew it was plenty hot, hot enough to arouse even her loving, protective grandpa. What if some of the boys and men who lived next door could glimpse her from their tallest storeys? Would they leer at her barely legal body? Use their phone cameras to zoom in on her gorgeous melons and cute, hidden slit? Take pictures? Flop their cocks out of their pants to jack off to her while she lay there, clueless?

‘Hey, pussycat!’

Becca startled and sat up straight away, only to see Samson grabbing something from a cabinet by the house. When he stood back up and walked closer, she saw he was holding a bottle of sunscreen, which he shook a little as if to highlight it. ‘A hairless kitty shouldn’t be in the sun without protection. I think your mama cat wouldn’t be happy with me if I let you burn.

Rebecca hadn’t thought about that. The haze of arousal from his touch, her exhibitionism, and the fantasies of being watched had her feeling a little stupid. She reached out to take the bottle from him, but paused.

She hadn’t been out here long. If he’d come out here to warn her, that meant he’d seen her from his office. Maybe he’d been watching her supple form, taking photographs to beat off to later because of how rock hard his little girl made his old dick. Rebecca quickly glanced at his crotch and didn’t see any signs tenting, but that didn’t mean anything. Maybe he’d beaten off to her before coming downstairs. Maybe he still had some of his cum on his palms. Regardless, she’d enjoyed his touch so much, earlier on, and maybe this was the perfect opportunity for more.

Innocently, of course. A pet couldn't apply its own suntan lotion.

She lay back down, and lifted her hands up to her collarbones, knees together and raised, posing like a real cat on its back. She looked up at her grandpa pleadingly, begging silently, and for a surprising second, she thought she saw something primal, frightening, and exciting flash over his features before he quickly went back to his usual gentle demeanor. She was probably seeing what she wanted to see, something that wasn’t really there. But still.

‘Of course. You need my help, huh?’ Samson chuckled, and sat on the edge of the chair to have her comfortably within reach. He popped the top off the bottle and squirted some in his hands before he started to smear it on her arms, first. Even this unerotic touch made Rebecca’s heart beat harder, especially as he had to lean over her to cover both her arms. She could smell his aftershave, and the smell of books and old leather that permeated his office. There was a thick vein on the side of his throat, throbbing a little as it pumped blood to his brain. His shoulders were so broad. She’d never noticed before.

She sighed happily when he massaged the lotion into her shoulders, and had to press her lips together to avoid a strange expression or sound when he moved on to slathering her stomach next. It was a part of her body others rarely touched, and maybe that’s why it felt extra sensitive, capturing the rough texture of his fingers and fizzing with little hotspots of pleasure when he dug his fingertips harder into the space around her belly button, then just over her pubis, like he was knocking on the door to her womb through layers of skin and muscle.

Well. More like the window. He’d have to touch her differently to reach the door

It was on that thought that Samson took the bottle, upended it, and splashed some lotion directly onto his granddaughter’s full, trembling titties. Rebecca gasped at the sensation, which just made her breasts jiggle again, two shaky mounds on her narrow teen chest. The liquid was warm, clearly heated up in the sun-beaten cabinet, and its viscous texture on her boobs was unlike anything she’d experienced before – but she didn’t have any time to focus on the feeling, because without pause, her grandfather began running his hands over her tits.

Unlike earlier, when he’d avoided all but the edges of her breasts, he now focused on them. Rebecca’s mouth dropped open at the new feeling of strong, masculine hands kneading her tits, her grandfather’s fingers expertly rubbing circles into her hot young flesh and making sure to tease her stiff little nipples whenever his lubed digits came anywhere near the sensitive pleasure nubs. She looked down to watch her grandpa massage her soft, pliable pillows, and although she was very much feeling every aspect of this touch, she could barely believe what she was seeing.

By the time he was done covering her chest in lotion, her breathing was noticeably heavier, and her mind was spinning. She’d hoped her grandfather would be more daring, but she hadn’t expected her virgin tits to be so expertly played with, and she knew her pussy lips had to be full and glistening now, beginning to part to beckon in whatever breeder had turned her on this much. 

The problem was that the breeder in question was her own doting granddaddy, and he’d soon be seeing the effect he was having on her, because he was sliding down the chair to cover her legs in sunscreen now and he’d only have to follow the lines of her thighs to see her cute teenage slit in bloom.

Becca waited, the massage beginning on her shins and working its way up her smooth legs, paradoxically relaxing and unnerving. Samson rubbed and kneaded the sides of her shins to get to her calves, then her elegant thighs, and then, he flattened his palms and fingers to push up, thumbs caressing the insides of her thighs before they touched the bottoms of her pussy lips and moved up in unison, opening her slit to see the pink inside, coating the tips with her slick, and pushing gently against her throbbing little clit before backing off entirely.

Becca lifted her hips with a little whine, chasing his hands, then settled back down slightly mortified at her wanton behavior. Her mind was clouded with lust at this point, though, and she was stared at him with shining eyes. Her breathing was so heavy she was almost panting, and Samson noticed. He rubbed the last of the suntan oil off on his forearms – along with the smidgen of his granddaughter’s pussy drool – and smiled.

‘Well, kitty, you’re sounding more like a doggy than anything else. Maybe I’ve had it all wrong, huh?’

Without further explanation, he loped off towards the house, and Rebecca instinctively leapt to her hands and knees and scurried along. It felt good to feel her tits hang below her and give her clit a little stimulation, even if just from her the movement of her thighs, but more than that, she wanted to know what her grandfather meant. His words sounded like a promise or an invitation. She was slow to move, though, especially on the grass, and by the time she got inside, she heard his car start out front.

Sullenly, she returned to the garden, figuring she might as well catch some rays now her body was completely covered in sunscreen. She couldn’t think clearly enough to read or even watch something, anyway. She could only think of those hands all over her inexperienced body, the looming, heavy promise of intense sexuality, just how fucked up it all was. Most of all, she worried he’d come back after her classes were over, and that she’d have to wait and see what would happen the next day.

It was crazy to think so little time had passed since their relationship was normal. And it still was , wasn’t it? They hadn’t breached a point of no return yet. Okay, he’d touched her tits, but he was helping her out. And he’d touched her cunt, however briefly, but –

Rebecca heard the French doors open, and jolted upright. Samson stood there, holding a plastic bag and beckoning for her to come in. They probably had enough time for – whatever was going to happen.

With trepidation, Becca hurried back inside.

Though she’d been naked all day, she felt more exposed than ever. Her skin shone with the thin layer of lotion coating every inch of her front, and her grandfather was now more intimately familiar with her adult body than anyone ever had been. She knew he’d washed her as a child, and remembered the fun bath times with him. She’d never imagined she’d feel his touch on her sweet vulva for anything other than a quick hygienic wipe. Now, she sat on the floor, hands folded on her lap, waiting to see what he’d do. Samson was rummaging in the bag. He smiled at her over his shoulder, and turned around, holding something.

A leash and collar.

Rebecca’s stomach dropped, but it seemed to crash right through the bottom of her torso to make her snatch thrum with desire. Samson squatted down and waited for her to come closer, because he knew she would. And he was right. His granddaughter haltingly crawled to him, cheeks a pretty pink and plush lips parted in anticipation. The collar was made of good quality leather, the leash made up of a matching handle and a length of steel chain. It was unmistakably for an animal, and it fit snugly around her neck when he gently fastened it onto her.

‘Looks like I got the right size. You’d be surprised how many different kinds of collars there are. Well, I guess you wouldn’t. Dogs don’t think about those things, huh?’ Becca only made a small noise in her throat, which made him pat her head and stand up. ‘Let’s take it for a spin.’

He took a few steps until the leash was taut, and glanced back encouragingly. Rebecca had no choice but to follow the pull on her neck, and shuffled behind her grandpa on all fours, forced to take bigger “steps” to keep up with his walking speed. She could hear the lips of her dribbling pussy separate and reunite when she moved, squelch squelch, hyper-aware of how exposed her holes were as she hurried along, and she was glad Samson was in front of her so his eyes couldn’t devour her ass and cunt while she was helpless to do anything about it.

‘There we go,’ he murmured as they went around the room, ‘good girl.’

When he seemed satisfied, he stopped and looked down at her. The situation was insane: Rebecca, on her hands and knees in front of her grandpa, naked as the day she was born – and he’d actually seen her on the day she was born, though she’d been cleaned up and put in a little bodysuit by then – save for a dog’s leash. He smiled, leaning forward. ‘What a talented puppy. You knew just what to do. How about this?’

He held out a hand, palm up. Rebecca looked at it for a second, then hesitantly raised an arm and placed the tips of her fingers on his, which made him outright beam at her. ‘Give paw! Good girl. Good puppy!’

He raked his fingers through her hair again, and that added to the compliments filled her with a nonsensical pride, as if there were anything special to what she’d done. It was nice to be praised, to be appreciated, for the little things. To live easily. Samson crouched down to affectionately rub her bare back, and she arched her spine down to lead his hand up and down the valley that created, shivering at the way he tickled her soft skin. As she was on all fours, stomach down, he had to reach below her to pet her belly, which made those familiar sparks of arousal collect in her vagina – even before he lightly skimmed a hand over the tips of her hanging breasts. She gasped when he did it again, and had to bite back a moan when he started flicking her nipples back and forth. ‘Hmm, actually, I don’t know if you’re a puppy . With nipples like these, big, sensitive and rubbery, it feels more like you’re a bitch who hasn’t been fixed. Or a little heifer.’

Both terms made the thin hair on Rebecca’s arms stand on end, and as he kept stimulating her vulnerable tits, she started breathing harder, squeezing and relaxing her pussy to get the slightest bursts of pleasure in her poor ignored cunt. She heard her grandfather’s breathing quicken and deepen, too, before it was drowned out by her first uncontrollable, guttural moan as he closed his big hands around her udders and started milking them, squeezing first one, then the other, rubbing his fingers into the tender flesh when he pulled down, like he was truly trying to wake up her dairy ducts. 

‘Nothing coming out. Maybe I’m not doing it right.’

The chain clipped onto her collar tinkled with her shudders, and she vainly tried to stifle her pleasured groans. This was like the tit massage he’d given her earlier, but heightened, humiliating and glorious all at once. She’d never been this turned on.

Grandfather and granddaughter startled when his smartwatch let out a loud notification sound, and Rebecca’s boobs felt tingly and cold after being so thoroughly manhandled, then abandoned. She glanced at Samson, who turned the noise off and spoke as if to himself: ‘Summer school’s out for the day in five minutes. Becks’ll be back soon. I guess that’ll be your cue to go, huh, cow-kitty?’

Becca sat back on her haunches, visibly dazed, her breasts blotched red where her grandpa had grabbed them and her nipples hard enough to cut glass. The leash lay on her chest, between her boobs, and she didn’t have the presence of mind to think what an erotic sight her young body must be in this condition. He got back up on his feet, paused, then leaned down for a final grope of his granddaughter’s tit, grabbing it fully with his hand and running his fingers to the tip to give her stiff nip a pinch that had her whining and tightening her legs.

‘Thanks for stopping by again,’ he said, turning around to head to the stairs. For the first time that day, Rebecca saw a bulge in his pants, a thick fucksnake slithered halfway down his left thigh, brought to life by playing with her body. ‘See you tomorrow, maybe.’

She sat in place until she heard the door to his office close upstairs. Her heart beat hard in her chest and her pussy.

How far would this game go before the week was out?
