Grandma's Secret Side Hustle
 
  It was a rainy day when your parents drove you over to grandma's house. Clouds were pinned to the sky like a moth-eaten shroud, and let loose a decent drizzle that dampened the road and formed a fine mist over the car's windows. You paid little mind to it, instead focusing on the weird, electric pop-music that played through your nice set of headphones. Top-of-the-line, funny enough they were a birthday gift from your grandmother. Bemused by this fact, you watched the landscape sweep by.
 
Of course, you could've easily driven over to her place yourself. You had, after all, just turned twenty-one. But your folks insisted that they take you themselves. "Oh, it's no trouble at all," your dad said. "It's on the way to the airport!" your mother added with a reassuring smile.
 
Never one to argue, you accepted their reasoning and let them drop you off. It was the least you could do, since you were such a disappointment.
 
Frowning, you breathed heavily on the glass and aimlessly traced through the fog before it vanished. Yup. There was no denying it. You were a grade-A, board-certified, never-going-to-amount-to-anything loser. A scraggly-haired coomer who spent all his time watching anime, playing video games, jacking off, or some combination of the three. Nothing more, nothing less.
 
Oh sure, you tried to follow the script properly. Did decent in school, got accepted into a good college nearby. But none of the classes interested you, and after a semester you dropped out. After that, you tried your hand at minimum wage employment, but a couple of fry-cook jobs later you discovered you weren't cut out for that either. So now, you scuttled back to the safety of your bedroom, where you could masturbate to your anime figurines in peace. Thankfully, your parents were both well-off and kind enough to let you back in, but deep down you could sense the disappointment they hid for your sake. You tried your best to help out around the house, but you knew no matter how many dishes washed or clothes folded it would still be there. Really, you started to wonder if you did it for your sake or theirs.
 
Still absorbed in your music, it took your mother's gentle nudge to break you from your self-pity session. "Honey, we're here." She said, as you tucked your headphones into the backpack that carried your laptop and phone in it. After grabbing that and the small suitcase of clothes from the adjacent seat, you kissed your mom on the cheek and wished her and your mustachioed father good-bye. They had decided to travel to Hawaii for this year's two-week summer vacation. Never one who enjoyed walking across hot sand under a blistering sun, you opted out this time to stay behind. Personally, you thought you could handle yourself well enough for a couple of weeks, but your parents insisted that you lodge with grandma. At least with her they knew you'd be fed hearty, home-cooked meals, they probably told themselves. So you agreed, happily so even. Though, not quite for the reason they thought.
 
Closing the car-door behind, you turned and waved your parents off as they drove down the suburb's road that eventually led back to the highway. As their car disappeared behind a row of finely-trimmed hedges, you appreciated how nice the two-storied houses that lined the sidewalk were. Maintained on the daily, they were comfortably middle-class, both in size and standardized design. Ripped straight out of a Friday night, prime-time aired sitcom, you mused, before you turned around and walked up the concrete sidewalk that led to the house's front door. Knocking on it, it didn't take long for its owner to come out and greet you.
 
"Well, if it isn't my favorite grandson!" Your grandma exclaimed, enthusiastic for your arrival. Smiling, you jokingly reminded her how you were, in fact, her only grandson.
 
The elderly woman threw her head back in laughter. "Oh, you'll have to excuse me, dear. My memory isn't quite what it used to be. Now, come here and give me a hug already!" Excited, you were more than happy to oblige. While you hugged her, you felt her humongous tits mash against your chest, and over her shoulder you saw how snug her denim-jeans fit across her juicy ass. For a split second even, your balls brushed against her own, and this almost caused you to melt in her arms. Fortunately, you composed yourself and pulled back at the appropriate time, though your gaze still lingered on the thick bulge that ran from her pants and under the lavender button-up shirt she had on.
 
Unaware of your sinful thoughts, your grandma cheerfully bade you to come in. "Don't just stand there and get wet, dear! Come in! We have so much to catch up on." Her hips hypnotically swayed from side to side as she strolled deeper into her home. Back turned, you felt confident enough to stare at her generous curves while you followed suit.
 
Plainly put, your grandmother was a smoking hot GILF. You knew that ever since puberty struck and made you realize just how sexy she looked in her sling-shot bikini whenever she swung by your house to swim in your folk's pool. The fact that she was a well-endowed futanari, as expected of your level of degeneracy, only enticed your hormone-addled brain further, and churned your loins into a frenzy. Hell, nearly seven years later, and she still looked just about the same. A little wrinkly near the corners of her eyes and mouth, sure, but the rest of her milky-white skin was smooth and taut. Her hair, while snowy-white now, was still luscious and long enough to maintain the braided pony-tail that seemed to be her favored hair style. Even her voice remained sonorous and crackle-free, and her liveliness only made her seem that much younger.
 
She was definitely still a tempting catch for someone who started her seventies last year. At least, that's what you figured. Of course, this was a bitter-sweet recognition. Although the old girl had been single ever since her husband passed away while you were learning the alphabet, she'd forever remain out of your reach. What with the whole incest taboo and everything. Nevertheless, you figured that being around her for a couple weeks would give you plenty of opportunities to ogle. Maybe you'd even get lucky enough to 'accidentally' walk in on her while she was undressing. The possibilities, so your lecherous brain calculated, were endless.
 
All things considered, these couple of weeks at grandma's were shaping up to be pretty interesting.
 
...............
 
The evening passed about as predictably as you expected. Not that it was tedious either. Much of it was spent simply talking with one another, either in the living room while watching a melodrama or in the kitchen where your grandmother prepared a mouth-watering stew.
 
Overall, it turned out to be a very pleasant discussion. While your extroverted grandmother dominated most of it, you enjoyed listening about her life before retirement. Her childhood, her career, her love-life, all told with her usual dramatic flair. She seemed to have a thousand stories locked away, and she wanted to relate every one of them to you. Ashamed of your own colorless existence, you happily basked in her dazzling vibrancy. Unaware how the depraved lust that lurked in your soul towards her was being purified into love.
 
Eventually, however, the conversation had to be put on pause for the next day. After you helped clean the dishes and sat next to her on the couch to watch the local news for a couple hours, she rose and declared that she was ready for bed. Though you weren't tired, you certainly didn't want to be a bother either, so you lied and concurred. After that, the two of you separated to your respective rooms and prepared for the night. A quick change in dress that left you only in your underwear later, you logged onto your laptop and started to binge the latest paint-by-the-numbers isekai you'd been dying to catch up on. Privacy secured by the wireless headphones you had, you managed to get through half the season before your bladder ached.
 
Sneaking into the adjacent hall, you padded over to the nearby bathroom and finished your business. Weary-eyed, you felt now was as good a time to tuck in. Just as you flipped the incandescent bulbs off, however, you peered over to your grandmother's bedroom, and noticed a sliver of light slip out of her doorway, penetrating the darkness. Curious, you quickly realized how opportune the discovery was. At last, you could catch a glimpse of the voluptuous old girl in all her glory!
 
Awakened, your cock twitched and tented your cotton-white undies.
 
Without hesitation, you heeded its call. Slowly, you tip-toed across the polished wooden floor, deftly able to avoid making any more creaks from your weight than was necessary. Finally, you had reached her bedroom's door. Erect, and prepared to burn whatever images you could snatch in your mind's eye, you hid behind the heavy door and tilted your head to stare into the couple inches of opened-up space.
 
Shocked, your body shuddered at the divine sight that had waited.
 
Hunched over on a lavish office-chair, your grandmother stared intently at a flat-screen computer monitor. Just as you prayed for, she had changed into her pajamas. A silky lavender nightgown, the garment left plenty of her bust exposed, and apparently wasn't even enough to cover her pendulous balls. As such, her girthy dick shamelessly poked out of her cleavage, and ended just inches away from her chin. Heart fluttery, you traced her figure with your gaze and drank in its curves.
 
What you hadn't forseen, however, was that she would be filming herself.
 
You knew she was, given how the silvery ball of a webcam that was attached to her monitor's top blinked to signal it'd been powered on. If that wasn't a gigantic enough clue, your grandma's lewd smile and flirtatious giggles certainly were. Seductively, she leaned forward and cupped both her breasts, before suddenly she pressed them together to give herself a titjob. Cooing, she started to whisper to the camera.
 
"Mmm, isn't that nice? I bet you all wished this was your cock instead, hmm?" Eyes-lowered, she chuckled. "Too bad. I'm sure none of you are nearly as big as I am. You really think your puny pricks are good enough for granny's knockers? They'd probably just get lost in them. But that's exactly what you guys want, isn't it~" Lusty, she scooted even closer until her unfathomably large jugs threatened to tip the computer over. Her nimble hands moved faster and faster, yet the superior grin never left her face.
 
Aroused beyond belief, you probed your underwear until your hand grazed the shaft within. Gripping it, you immediately started to pump it as you spied on the carnal show. Thanks to the angle of her desktop set-up, and how her front was reproduced on the monitor's entire screen, you were able to feast on the body-parts that mattered at the moment. Of course, all thoughts on why your grandma was doing any of this in the first place went completely out the window. For now, the only consideration you had was on rubbing a quickie out before she noticed your presence.
 
So enthralled to the pursuit of pleasure, you didn't realize how you had propped your body against the door, or how, weighty as it was, it still shifted under your movement. By the time you did, it was already too late.
 
Gracelessly, you stumbled forward, balance way off, until you fell on your side, groaning.
 
Startled, your grandmother gasped and swiveled on the chair. "Honey! You're still awake!?" She yelped. Fingers trembling near her mouth, she was mortified by the unwanted visit.
 
Embarrassed as well, you looked up and tried to explain yourself. Hand firmly under the bulge in your underwear, however, you discovered how bereft of words you'd suddenly become. And so, the two of you awkwardly looked on at each other, unsure of what the proper response to such a situation could possibly be.
 
As usual, your grandmother was the first to take the initiative. Turning around, she fumbled with the webcam for a bit. "Oh, come on," she whispered, frustrated by its senior-unfriendly design, "why do you always have to be so . . . there!" Through a chance combination of buttons mashed, she had managed to turn the camera off. With that, she spun back around and sighed. "Well, there's no point fibbing to you. You're a man now, and nothing I could say would fool you anyway. So, to be quick about it, yes. I was filming myself naked so I could upload it to the Internet."
 
Anxiously, you raised your hand off your genitals and asked why.
 
"Money, of course. Couple months ago, I found myself a little short on cash, but I overheard at the grocery store some of the cashiers talking about how much they made by, well, selling naked pictures online. After doing a little digging, I found one site called 'OnlyFutas', and decided I'd give it a shot." At this, she shrugged. "Turns out there are plenty of people out there who'd like to see me in lingerie."
 
Shifting, you asked why she hadn't simply asked your parents to spot her some money.
 
Hasty, she shook her head and smiled. "Oh, I couldn't do such a thing! It's not like what I wanted was important anyway! It was a luxury, really! Your grandfather was a good provider. He made sure to leave me plenty in case . . . in case he was gone." Her voice wavered, and she rubbed her shoulders, a distant glint in her eyes. Worried, you got up and walked over. Sitting on the corner of her nearby queen-sized bed, you placed a hand over her thigh. Despite how tantalizingly close her balls were now, you didn't even care at the moment.
 
Grateful at your care, your grandma stroked your back. "T-thanks, dear. You always know how to take care of me." Softly, you stroked her back in turn. After a few seconds of comfort, your grandmother spoke up again. "Y'know, honey, I wasn't being entirely honest before." Another pause passed before she elaborated. "I say it was money, but that's just how I justified it to myself. Really, what I wanted was the attention. To know that there were still people out there who found me . . . attractive, even now. That's silly, and someone my age should know better, but to learn that felt nice." Again, she turned away from your gentle gaze. "I-I'm sorry. Old hags like me shouldn't dump all their insecurities on young people, especially not their grandkids. Please, forgive me."
 
Fed on cheesy romcom anime as you were, you figured there was only one thing you could say. Suddenly snatching her by the wrists, you looked directly at her and said, with complete sincerity, you thought she was the most beautiful woman you knew.
 
Taken aback at the confession, she snorted and dismissed it with her hand. "Oh please, dear. Don't think you have to give fake compliments just to appease me. I'm not that frag--" Again, your utter lack of real-world romance experience guided you. Without hesitation, you cut her off by kissing her on the lips. Since it was your first one, it was a bit messy, but fortunately when you pulled back she looked more astonished then disgusted.
 
Blushing, your grandmother blinked, bewildered. "Oh!" Mouth puckered into an 'O' face, she looked back into your eyes, this time with a seductive smile. "Oh my . . . I didn't know this was how you truly felt, dear." While she shifted in her office chair, her thigh bumped against your rock-hard boner, and caused it to jiggle ever so slightly. She glanced down, and her smile became toothy. "Mmm, oh yes. This definitely proves your not lying." Fingers clawed, she stroked the lump through the cotton fabric. Reflexively, you bucked your hips at her nimble touch. This, in turn, caused her own prick to throb and push against her nightgown.
 
"I suppose I should've seen the signs sooner. You always were a little too eager to take me up on my request to rub sun lotion on my back in the summer." She remarked. "Maybe I should've been more careful with how I showed off my body around my horny grandson. But I didn't, and now it seems you're obsessed with it." Panting, she leaned closer to you. "But that's okay. You're a man now, after all. So maybe I should start treating you as such~" Her tone clearly flirty, she cupped your cheeks again and gave you a longer, deeper kiss. Eager to explore her mouth, you pushed your tongue against her lips and tried to pry them open. But then, she suddenly pulled off of you, giggling.
 
"Hang on, sweetie! I know how badly blue-balled you must be, but there's no reason to rush things. Besides," she elaborated, and gestured back at her monitor, "don't you want to help your poor grandma make some cash while you're at it?"
 
Like a puppy, you furiously nodded in agreement. Pleased by your enthusiasm, your grandmother beckoned you over. "Well, let's get started then! Oh, but I'll let you handle the tech this time. I can work with it sometimes, but its still a big pain in my fat ass." Jumping up, you stepped past her to get the monitor and webcam up and running. As you set it up, you admitted that you were never good at acting.
 
"That's okay, honey. You don't have to say a word. Just let me do all the talking and work. I promise, this old girl still has plenty of surprises for you." Reassured by her confidence, you completed the process and stepped back. Light flickered on again, the image of you and your grandmother was reproduced on the screen. Smooth and in high-definition, practically every detail, down to your pasty skin, was captured.
 
Like a true professional, your grandmother smirked and waved at the camera. "Hey, all you GILF-lovers out there! It's me again. Sorry for the late upload, but today I have a special treat for you." Upbeat, she wrapped an arm around your midsection and pulled you close enough for your crotch-bulge to indent her right boob. "It's my grandson! Isn't he precious?" Gently, she tugged on your arm. Thanks to the sheer amount of porn you consumed, you had a pretty good gist of what she wanted. Slowly, you crouched until you were next to her soft cheek.
 
Mouth puckered, she gifted a chaste peck to your left cheek, along with the scarlet imprint of her lips that remained. "I could just kiss him until he passed out!" She declared for her audience's benefit. Soon enough, however, her expression turned far less innocent.
 
Her tongue flicked out, and with that she pulled you in for a sloppy French kiss. Anticipating this, you allowed the moist appendage to push over your teeth and stroke your own tastebuds. Its intensity was overwhelming. Knees buckled, you weakly humped the senior's boob while she continued to poke around, and as her saliva mixed with yours until it spilled into your throat. A tiny wet splotch appeared on your tidy-whities, the result of the precum that your cock had released from the near-orgasmic bliss of the make-out session. Enraptured, you clenched your eyes shut and happily moaned.
 
Finally, your grandmother pulled back. The thin thread of spit that connected both of your mouths snapped soon after.
 
Grinning, she smacked her lips with porn-star like gusto. "Other grandsons may not like kisses from grandma, but not mine!" Shaky, you nodded in approval.
 
Not skipping a beat, she pointed at your messied underwear. "Oh dear! Seems like he got a little too excited. Then again, so have I!" Her cock throbbed, threatening to break free of its silk-prison. "Here, honey, why don't we get these pesky clothes off already? I might be too tired tomorrow to do the laundry, after all~" Fingers twitchy, you snatched your underwear band and hastily lifted your legs out of it. More leisurely, your grandma raised her night-gown off her gigantic tits. Flopping out, they also allowed her girthy phallus to swing down and slap her thighs before standing at a lower angle.
 
Soon enough, the two of you tossed your respective clothes to the side. Already, your brain was awash with a thousand sins you wanted to commit with her luscious body. Eyes tracing the tiny blue veins that ran across her tit-skin, you were equally overjoyed at her more tan shaft, and the brick-red mushroom tip that capped it. Finally, you settled on a simple handjob.
 
Hand ready, you wrapped it around her schlong and clumsily stroked to her balls.
 
Gasping, your grandma quickly regained her bearings. "Oh my! Such an eager young man, isn't he?" She asked, rhetorically, before she responded in kind. Dicks now out in the open, it was obvious who was bigger. While yours was comfortably average, her meat-slab was enormous. Thick around as a soda-can, it was nearly a foot and half long. Before long, your hand grew tired from having to cover so much flesh, and it ached. Still, you persisted, determined to keep her hard for whatever she planned ahead. Of course, this was easier said than done, especially when her own deft touch was applied to your far weaker prick.
 
Thankfully, she seemed to understand the strain. "As fun as this is, dear, what do you say we take this to the bed?"
 
Graciously, you nodded. Smiling, your grandma hopped off her office chair and crawled onto the nearby bed. Before you could accompany her, she gestured towards the monitor. "Don't forget the webcam, dear! They have to get a good view of us." Stepping back, you hunched over the computer and shifted the monitor on its stand until it faced the bed. After peering back and nudging it to adjust the angle, you turned back. Lurching onto the mattress, you asked if you'd ruined the video.
 
She waved off your concern. "Don't worry, dear. We can always fix it in editing." She said, keeping her voice level to a whisper. "Now, be honest, and tell me if you want to fuck me first." Contemplative, you screwed your face up and considered the question. After a few moments, you looked back at her and said you'd prefer it if she had the first go at it. Grinning, she gave you another kiss. "So courteous! Alright then, we'll do it doggy-style first."
 
Speaking up, she looked back at the webcam while you scooted past her on hands and knees. "Seems like he wants to start by having his own ass pounded! Such a dirty, dirty boy. But I'm sure he speaks for all you, so I'll give him an extra big load for you pervs." She let out a haughty laugh while you rested on all fours, ass perked up to receive the inevitable dick. Sliding over, your grandma suddenly grabbed at your own cock that swung underneath. Startled, you gasped as she focused on the head for a moment before she pulled back. Palm covered in your own pre, she used it to lube up the upper part of her shaft.
 
Then, left hand raised, she slapped your exposed derriere, hard. Yelping you felt the imprint of her palm sizzle on your tender buttock. "What an ass! Nice and untouched, just for me!" Her member flexed, and its head grazed your virgin butthole. Meekly, you begged to be destroyed. Cooing, she ran her fingers down your hair before she suddenly clutched a fistful of them. "Don't worry, slut. 'Rough' may as well be my middle name. Now, bite that pillow, sweetie. Grandma's gonna wreck that tight ass!" Hips pulled back, she slammed her dick right through your pucker, not stopping until her base collided with it. With a howl, you clutched the bed sheets and peered down at the bulge that poked through your lower abdomen. For a moment, you watched it quiver from under your skin.
 
That's when she started to thrust.
 
Faster than a machine, she made sure to pull as much of her member out before she shoved it back in. Teeth clenched, you cried out at the violent assault on your prostate.
 
"Ah! What a firm hole he has!" Your grandmother declared. "But not for long. When I'm done, it'll be so loose that regular dicks will just fall right in! Then only I can make him cum by hammering his prostate!" She continued with a laugh. Her nuts smacked your butt loud enough to echo in the room. Meanwhile, you whined and groaned, feeling the meaty rod travel up and down your rectal cavity every second that passed. It felt like you were being skewered on her cock. In essence, you were.
 
Lungs jumping and body quivering like a mound of Jell-o, you were uncomfortably erect. Though your precum flowed out now, the urge to cum already burned inside. In your desperation, you knew the only way you'd climax was if your grandmother did. Realizing this, you clenched your cheeks together with all your strength to grab her attention. Her husky groan was proof enough you succeeded.
 
"Oh? You already want me to cum in your ass?"
 
You nodded, and pushed yourself back to confirm it.
 
"Alright then. But only because you're such a good grandson."
 
Lurching forward, she grabbed you by the shoulders and rested her fat melons across your back. Once she did, she grunted, and forced herself faster and deeper into your rectum. Creaking, the bed shook from her powerful thrusts. Jaws grinded, she rested her head to your left, and whispered in your ear. "Get ready, dear. I've been holding this one in for hours now." Her hot breath tickled your ear-drum, and got you even more excited. Eager to orgasm, you swayed your back from side to side, just enough so that her plump nipples would brush it.
 
Sent over the edge, she plunged forward and released her pent-up spunk. "Unngh!"
 
In seconds, her milky-white splooge rushed into your lower intestine, and filled your belly with its warmth. Sensing this, you came immediately afterward. Smaller than her load, yours nonetheless was enough to drizzle her sheets with thin lines of seed. Shuttering, you almost bit down on the nearby pillow hard enough to tear it. It was, undeniably, the best orgasm of your entire coomer life.
 
After a while, how long you weren't sure, your grandmother finished and backed out. Unclogged, your gaped anus leaked more than a few drops of splooge out as it cooled and shrunk to its normal width again. As it did, your grandmother pointed at it for the camera. "See? All stretched out now! I bet you all wished this was you instead, hmm?" Casually, she smacked your ass with her engorged mushroom head. "Come on, sweetie. We can't leave the viewers waiting too long."
 
On unsteady limbs, you scooted in reverse and allowed your grandma to take her place on the bed. Turning on her back, she lifted her legs high into the air. "Seems that my dear grandson wants to fuck me in the mating press position. Silly boy! He should know there's no way he can impregnate me now. But a deal's a deal."
 
Standing up, you waddled forward on the springy mattress and grabbed her by the ankles. Then, legs bowed, you lowered your pelvis down until your prick poked her nuts and gently pushed under them. It was there, safely tucked under her pendulous balls, her pussy quivered from the touch. Impatient, you prodded her folds until you sensed where her proper hole was located. Hastily, you crammed yourself in and started to hammer it like there was no tomorrow.
 
Hot and slippery, you instantly thought it was the most perfect snatch in the world. Admittedly, you hadn't penetrated any other one, but you couldn't care about such facts. Instead, all you focused on was not immediately ejaculating like the pathetic virgin you were.
 
Eyes rolled towards the ceiling, your heart thumped. The memories of the previous few hours suddenly washed over as you continued to pump into your grandmother. Maybe it was merely the ecstasy of finally getting laid, or the inherent immorality of who you were fucking, but it was then you realized how much you wanted her to bear your own children. Without thinking, you confessed as such to her.
 
Devoid of contempt, her face remained playfully gentle. "S-silly boy!" She repeated, albeit with a faint blush this time. "My womb's as barren as the desert is now. You could cum inside me a hundred times and still not impregnate me!"
 
Lovingly, you nuzzled her right sole. You didn't care if it took a million times. One day, you'd do it. And the same pussy that pushed out your mother would then push out your own baby. Of that, you were certain.
 
At a loss for words, your grandmother stayed quiet for a bit. Soon enough, however, she grinned, and contracted her vagina around your shaft. "Well, seems my grandson's more of a romantic than I thought! Fine. From this day on, condoms will be banished from my home. And you'll have to pound my pussy at least once every time we play!"
 
Boobs and dick clapping against each other from your thrusts, she screamed above the noise. "Come on! Stuff granny with your manly seed."
 
Gratefully, you complied.
 
Spit flung off your tongue, you plunged down with all your mustered strength. And after the fifth push, you came.
 
Surging into her twat, your cum soon filled her womb to the brim. Tongue lolled out as well, she also came from both genitals. Her jizz shot onto the nearby wall, and dripped down its sheet-rock surface. Impressed, you were compelled to remain inside as long as you could manage. Thanks to your determination, your cock sputtered out a couple more spurts before you knew it was done for.
 
'SLOP!'
 
Like a drain-plug to a bathtub, your cock popped off her pussy. Stumbling, you fell over and sprawled yourself across the bed. Legs more gelatinous than usual, your prick hung limp, and shrank. Embarrassed, you covered an arm over your eyes. While normally it took four or five orgasms for you to go soft, it seemed that actual sex was a whole different league than masturbation. As such, you were spent.
 
In contrast, your grandmother was still rock-solid, and her casual movements suggested she was nowhere near being finished herself. Quickly, she crawled over to you, her dick leaving behind a trail of slime as it jutted from under her.
 
A momentary glance of your own member told her everything. "Hey, honey. You think you're up for another round?"
 
Weakly, you told her you couldn't.
 
"That's okay." Soothing as always, her reassurance made your ego less bruised. "Sex is always more intense than masturbation. We'll practice to build up your stamina. But for now, why don't we end it like this . . ." She scooted over and knelt down right beside your ear, whispering in it. As she explained her plan, your flushed face grew a grin on it. Nodding, you agreed to it.
 
Sliding back, she made her way towards the bed's headboard. "Aw, is my wittle grandson tired already?" Back propped up against the flat slab of polished wood, she spread her legs out, allowing for plenty of room for her nuts to breathe. "That's okay. I know just the place where sleepy boys can go to rest." Finger curled, she beckoned you over.
 
Energy slowly being restored, you rolled over and swiveled on your butt until your feet were right above her hot tip. Then, slowly, you clamped them side by side, lowered them down, and pressed your big toes gently into her awaiting urethra. As they sank in, your grandma cooed at their touch. Meanwhile, you continued your feet in. Gliding over your digits like how a sleeve would, the cock easily grew to fit them in. Soon enough, both feet had been swallowed through, and the slit was now working up your ankles.
 
Encompassed in moist, gooey warmth, your toes wriggled. It reminded you of when you sometimes wallowed them into wet mud as a kid. Only this felt much, much better.
 
A few seconds later, and they had reached her nuts. Like a fabric of flesh, her sack conformed perfectly to your feet's broad arches and heel. Meanwhile, her slick slit swallowed more of your legs, until it finally reached your knees. By this point, you flopped onto your back and scooted back to make it easier to slide down her shaft. While you stared up at the blank white expanse above, your cock started to harden again. It seemed, after all, you did still have some steam left. Regardless, you ignored it for the moment and focused instead on the slimy warmth that oozed over your bottom half. You could always masturbate in her balls.
 
Cooing, your grandma shivered when she felt her penis head begin to crawl over your base. "Excited, aren't you? So was your grandpa. I lost count of how many nights he spent inside my testicles." She said, wistfully. Unsure if she was speaking for your benefit or the invisible audience of online pervs, you allowed her to continue in silence. "Oh, honey. You've made me feel like such a young woman today! There aren't enough batches of cookies in the world for me to thank you with!" At this, she chuckled. "Then again, this must be a far better 'treat', hmm? Now, come on, grandson! Get in grandma's nuts already!" Lip chewed on, she contracted her penis and sucked in another few inches of you at once. Up to your nipples in cock-flesh, you had laid your arms flat against your sides, intentionally so. Snug in her urethral canal now, the most you could do now was wriggle around. As the shaft snaked its way over your shoulders and neck to devour your head, however, you still enjoyed the sense of being trapped. Even as the darkness engulfed you, you smiled.
 
Outside, meanwhile, your grandmother's dick tamped down your messy hair before it finally consumed the top of your head. Monstrously engorged, from the outside it appeared like a flesh-colored worm had somehow swallowed you. Every contour of your average body, down to your twitchy prick and content grin, was exposed through the tight skin. Caught in high-definition on the monitor, your grandma stared on as you worked down her length to her balls. Though it took a little longer, eventually your entire body had reached them. Curled into a forward-facing ball now, it was a bit cramped. But the pleasant heat and gooey spunk that coated every square inch of you more than made up for that. Though you couldn't see her at the moment, you still gave your grandma a satisfied smile.
 
Shrunk down now, her thick phallus steadied itself near the top of your head. Given the human-sized sack it stood over, however, it seemed more like a fat stem on a fruit.
 
Happy at her superhuman feat, your grandma shifted her legs back so that her soles touched her mushroom tip. Quickly, she brushed them up and down her length, and grunted when an unexpected crack echoed in her ears. "Oh shit. I might be getting too old for this move." She admitted. Regardless, she continued the auto-footjob for a solid minute, until at last her cock spasmed and shot a stream of seed into the air. Falling in an arc, it landed squarely on her fat tits, and dribbled down to her nipples. Moaning again, she let herself cool for a moment, before she tilted her head back to the webcam.
 
Feebly, she raised both hands to her face and gave the camera a double peace-sign. "T-that'll be all for this video, GILF-lovers. Hope you enjoyed it, and I'll see you next time!" Weak smile on her face, she let it fall after a couple of seconds. "Shit! I don't think I can reach the computer with you in there . . . oh, nevermind! We can edit all this out later. Right now, this old girl needs to rest!"
 
Reclined on her headboard, she patted your head. "Don't stay up too late, dear. Tomorrow, I'll whip up a big stack of pancakes for you! You certainly deserve it." Content, she settled in and slowly drifted to sleep.
 
Engulfed in darkness, you also felt sleepy at the moment. But the layer of steamy spunk that tingled across you body excited you, along with the fishy odor of the place. Before you knew it, your penis was hard, and ready to cum again.
 
Of course, you were never one to ignore its call.
 
Hand between your thighs, you rubbed one out. And while you did eventually fall to sleep, it wasn't before you splattered the flesh walls with your semen a couple times while your grandmother snored away, a lewd grin on her unconscious face.
 
................
 
"Yes, sweetie, he's doing fine!" Your grandmother assured your mother over the phone. "In fact, he's been such a big help around here. Honestly, I don't know how I managed without him."
 
Settled on her couch, she held a remote in her other hand, and she had been preoccupied with her soap operas when she received a call. Near as you were to her, you could only catch snippets of the meandering conversation between the two aging women. Stuffed into your grandma's nutsack again, your butt ached against the wooden floor, and your legs splayed out at an awkward angle. Strained as your pose was, it was well-worth it to accommodate the space needed to pump your own prick with your grandma's flesh-light. High-end and battery-powered, it vibrated your shaft at an edge-inducing frequency, which could only be raised with a special app. Pleasureable as it felt, it was technically meant to help train you by increasing your sexual stamina. "It'll make our videos even better!", your grandmother explained. Ecstatic just to know there'd be more, you obliged.
 
"Sorry sweetie, but he's a bit busy at the moment to talk with you." She told your mom, her casual tone belying the fact that she also had a flesh-light slid snugly over her dick. Delivered just that day thanks to premium shipping, it had cost quite a bit. Of course, the senior could more than afford it now. "Yes, I'll tell him how much you love him, dear. Okay, make sure to drink a pina colada tonight for me! Love you, bye." Hanging up, your grandma sighed. "Phew! That was a lot harder to keep a straight face than I thought!"
 
Face right up against her ballsack's membrane, you asked how your parents were faring.
 
"Seems like they're having as much fun as we are. Your mom said she wishes they never had to leave."
 
Shifting against the couch, you admitted you shared the sentiment. At this, she chuckled. "Trust me, dear. So do I. But don't get disappointed now. You can visit me anytime you want." Still laughing, she opened up a bank app on her smartphone and appreciated how fat her balance was now. "In fact, the more often the better! Why, with how much money we've made, we could plan ourselves a trip to the beach. I know how much you hate the sun, but you'll love the bikini photos I can take!"
 
Panting, you rolled your tongue out to lap away at the salty spunk that coated her walls. Eliciting a squeal from her, you smiled, and cheerfully announced how you'd follow her anywhere she wanted. Smiling, she set down her phone. "Such a good grandson! Now, let your old grandma watch her programs. After that, we can finish what we started right here." Husky and deep, her voice tickled your ears. Then, she clicked on the T.V. remote and raised the volume again. While you could barely make out what the actors were saying, it made for a nice enough background noise to continue edging yourself with.
 
Cosseted in her balls, your mind mulled over how many more sex positions you could pull off before you had to return to your folk's place. There was, after all, still a week left at grandma's.
