GRANDPA'S HOUSEPET IN

SUMMER VACATION ⛱️ 🌞

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.
