Gainer Shake (Patreon)

The label really wasn't kidding when it read 'fast acting'... Like, I didn't expect instant... You sit there stoned out of your mind enjoying yourself but as I gaze at you from across the room it's almost horrifying. This shit really does work fast and now I'm feeling guilty for giving you TWICE as much of it.

"What?" You giggle, eyes red, donut in hand. I can hardly let words escape my mouth. You haven't even noticed yet. You lay back onto your bed and I watch hypnotized.  A moan escapes your mouth while you gobble down the glazed donut. "Fuuuck...". I can't even believe my eyes. You rest your arms at your sides. And all I can see is how fucking huge you are growing. This black market gainer shake was no joke. At view I see your belly bulging up towards the ceiling, rising and sinking while you breathe slowly. Your thighs swelling out, thick rolls forming between them, cascading downwards. Your calves are bloating and filling, engulfing your ankles with your feet becoming little loafs of flesh. "You-...you're-" I sputter.

"Hm...?" You attempt to sit up but fail, now realizing what's going on. I pause for your reaction. "Oh! I'm so heavy!" You grunt shifting your newly added weight around your bed.I didn't notice before but now I do.  Your ass and hips are growing quicker than everything else, your belly and thighs at a close tie.  "Oh! I...-I'm huge!" I can see the excitement in your face. Within half an hour you have gained I would guess nearly one hundred pounds, putting you at three eighty five-ish. I'm doing my best to hide my arousal.. "This feels so good...I feel so fat now-"

You jiggle your ever growing gut and I about lose it. You get yourself to the edge of the bed and heave yourself up to your feet. Which are being taken over by your bulging calf fat. "Here...feel this..." You wobble your insanely wide hips and they slosh back and forth. Fuck...I can hardly contain myself. I press my hands into your supple hips only to be met by feeling them swell.  I rub them softly and wobble them, working my hands up your apron of a belly where I lift it gently, feeling the heft spread outward and down onto your thighs.

You let out a slight groan. I can tell your sudden weight gain is really adding pressure to the rest of your body so I guide you back to the bed and lightly press you back into the mattress.  "How about I fill your tummy up with the rest of that box of donuts?" You moan between words, "Mmmf- yes!" Before you do anything else I cram another doughy sprinkled pastry into your mouth. You gobble it down and breathe heavily between bites readying yourself for the next one. You chew quickly and lick your lips, frosting and glaze forming around them.  "What a good piggy..." But then I noticed something. You seem to be growing faster.. Your ass spreading out from under you. Your upper arms are bloating and overtaking your forearms.  Your chest burying your neck, creating a wake of blubber up to your chin. "More!" You moan and demand. I hesitantly give you another creamy pastry and watch as you devour it. I pick up the gainer shake container and begin to read the label while simultaneously feeding you. I get to another section below the instructions. "Warning: Do not take with food. Give formula half an hour to activate. Food may speed up the process."

Oh. On top of giving you double the dose, I also gave you calorie loaded food. You smack your lips and demand even more. "I- ....I think we should slow down..." "More!" You grab the box and begin stuffing yourself while I watch in horror. You've tripled in size within the last ten minutes. You horf down donut after donut without a single clue that you're now basically too fat to roll yourself out of your own bed. "Wait-". I can hear your belly gurgling while you glut yourself even further into irreversible obesity. You consume the last pastry and go to wipe the cream and frosting off your chin only to realize within the last five minutes your arm had bloated so much fatter that you can't even reach your face.  "Oh-oh fuck...I-...I'm so fat-" You huff and puff between breaths. "How did I-...when-...?"

I can't even begin to formulate an explanation.. "But it was one box of donuts-...how-" Within seconds your belly surges upwards as you gain another twenty pounds almost instantly. "Oh god-that feels so good..." I watch as you struggle to sit yourself up, seven hundred pounds heavier. Propped up, your gut rests atop your swollen legs that are turning into lard filled tanks soon to only be used to store more fat. "Oh-it's so hard to breathe being this big-..."  I climb onto the bed, trying to repress my carnal instinct to roll you over to fuck.  I wrap my arms around your burgeoning belly, your skin almost hot from the rapid gaining. As I press myself into you, I'm pushed back little by little as I hear the sound of fat cells multiplying and stretching your skin. "Fuck..." I can tell how much you're enjoying this. You mush your hands into the rolls along your sides. "I-...I don't think I can move any more..." You whisper. I glance up.  I can no longer hold it in, my urges need to be met.

"Get up, pig." Your face suddenly red with frustration and embarrassment. I stand quickly to watch you struggle to move your now lard encased body.  "Don't try too hard, your pretty little heart might pop." I tease firmly. You wheeze and huff just trying to get to the edge of the bed. "I can't-'' You give up momentarily and lean back to catch your breath. "What's the matter? To filled with fat to do the basics?" I can't help but wobble your swollen belly. "To your feet now pig, or else." "Or else." I know for a fact you want the 'or else' You try again, inching your way to the edge of the bed again, your belly slapping against your rippling flabby thighs. In one brave attempt you launch yourself to your feet. Your calf fat nearly overtakes your plump feet and toes. Your thigh fat encasing your aching knees, cascading over one another and sagging towards the floor. "There we go...good." I circle around you observing every inch. You stand there suffering under your new found gain, wheezing and panting.

"I think it's time for cake." I whisper knowing the formula I just gave you would quicken again. "Yes..."While you stand there catching your breath I quickly run to the fridge to grab the triple chocolate cake I was saving for a treat for later.I come back to find you hefting your plump tits up playing with them."You ready?" I place the cake on the bed, not caring how messy our fun may get."Mmm...yeah!" "Eat." I command. You turn around, your enormous ass cheeks wobbling and jiggling with every half step you can manage and you bend over face first into the cake. Your mouth open as wide as it will go to take giant hoggish bites.  "Slow down, you're gonna pop pig!" As soon as words escape my mouth I watch slightly horrified as your gut begins to spread out underneathe you. Little grunts, sighs, and moans let me know you're no longer truly paying attention to how big you are growing. I stare, mesmerized at the rate your body is swelling. Fat packed into your short frame and you're getting heavier by the second. I step up behind your ballooning ass and roll my palms around your hips. They're wider than the door frame to my bedroom now."Mmmf- fuck me!" You demand. "I will. Keep eating." Terrified but too aroused to care I press myself between your colossal ass cheeks and wobble your bloated belly. I can hear you whimper while you scarf down more cake.

"You want it?" I tease. You waggle your entire rear end enticing me. "....fuck.." I can't hold it in anymore and try to find somewhere to stick my cock but... Your ass has grown bigger than what length I have so I press my hands into your supple hip fat and grind in between your massive cheeks. While you're bent over I can see the sides of your tits spilling out onto the bed like two puddles of flab to match your fat saggy belly. I work my cock between your ass and watch you struggle to stand up. "I bet you're going to blow past nine hundred pounds...keep eating for me..." I whisper softly into your ear. Pleasure filled moans leave me hard as fuck, throbbing, and ready to cum. "What if I can't move anymore?" You ask ready for my descriptive answer. "If you haven't noticed yet you're almost as big as my king sized bed. Once I roll you onto the bed it's over for you. You're stuck, and I'm only going to funnel feed you gainer shake and sugary desserts until you meet your premature demise..." Only half the cake was left. You wheeze and sputter trying to finish it for me. "I'm...getting too big-" I stop abruptly and force you onto the bed. “Fuck… you are heavy.” Your face reddens again."I know."

With all my strength I help you get to the center of the bed and roll you onto your back. With your little effort to move you are panting and wheeze trying to catch your breath. "There's no escape for you now tubby, I'm only going to fatten you up until you pop for me." Cramming cake into your greedy mouth I spread your fat laden, bulging thighs as far as I can. "Mmmf-!" Buried under hundreds of pounds of ever expanding blubber I see your wet flab filled fupa and start rubbing your clit in circles. Your face is so red. First from being so hot and bothered, second from the weight slowly pushing the air from your pathetically crushed lungs. "Cum for me.." A quarter of the cake left and your belly starts to form a round shape. "Mmmf-too tight!" I grin devilishly, "Yes you are..."

With ease, I slide my fingers down, your pussy hot and wet. My hand swallowed by soft warm rolls of fat.  My cock is so hard it's taking me all my willpower not to cum, but I know you need me inside of you. "Mmf-no...-mh skin is tight-" I watch as you struggle to lift your bloated arm up to your belly and you rub the side of it.  "Well my dear, the fat is probably struggling to find places to be stored. That's all you're going to be used for from now on."  You whimper again almost in tears, your pussy throbbing around my overworked fingers. "Don't worry, you have room to store it all or your body will just have to stretch a bit..." I enter three fingers.. "Hh-.." Your moans lead me to ready myself, I cream more sweet sugary cake into your awaiting mouth and remove my fingers.

You whine for more. I slip myself into you, your soft mound of fat cushioning every move. I reach for every inch of you, gripping and rubbing. With rythm your entire body ripples and quakes. I'm so fucking hard.  "I-cant breathe-" You struggle and gasp for air, pussy throbbing, wetness leaking into every crevace. "That's what you get for being a hog. Being a glutton comes with consequences." I speed up as I watch you writhe. Now completely imprisoned under over a thousand pounds of fat. You huff and begin to sweat a little. I put my ear to your stomach for a moment to listen to the cells and your stomach churn. "No! D-dont stop!" Heeding your command I thrust back into you and rub my palm over your clit. "Fuuuck..."

You're so wet I'm nearly cumming.." My stomach is getting tight! I'm going to pop-" You pant and groan, whining from the ecstacy of being stoned and living out your own fantasy. "Let's see if you do." I finish cramming the last bite of cake down your throat which is now buried under flab and tit flesh. "No more- I'm full! Please! My body will burst!"  You plea. You're growing so huge I'm having a hard time keeping my pace and staying inside of you. Your labored moans and panting quickens. "Good girl...I hope you got your fill." You scream, cumming hard. I thrust quickly catching up. "Fuuuck...."
