When Hollow realized she hadn't checked to see if Magma was into shortstacks, she goes ballistic and prepares a perfect scenario to see if it is something he likes.

Hollow keeps a little black book all about Magma, when she learns there is something she hasn't learned whether Magma likes it or not. She goes all out in a test to see if it's something he loves or hates.

The following fic contains: Shortstack, cum inflation, showers, milking, facesitting, transformation and enough cum to clog a shower drain. Reader discretion is advised.

Hollow's little black book

It was your average day at the milk mine with Hollow busy orchestrating a big order to be delivered soon needing more than a few hands on deck, as she roped Sneak, Queenie, Serenity, Rybbon and Thunder Cath to help her fulfill this order with them helping with the milking and bottling of the product while Hollow is reading as she is milked.

“Ugggggh I am so tired,” Serenity complains, putting another full crate of milk bottles on the cart before soon wandering over to a small stool and sitting down causing the wood to creak.

However due to the massive weight of her derriere the stool soon gives and breaks underneath her causing Serenity to fall down which catches the attention of everyone and leads to Thunder Cath bursting out in laughter.

“You think that’s funny!?” Serenity spits in anger staring daggers at the medieval enthusiast shortstack.

“Very much so,” Cath continues to laugh unaware of Serenity getting up and soon sitting down on Cath’s face silencing her laughter. The sounds of scared screams flailing of the small bugling ensues as she tries to get the gargantuan ass off her so she can breathe.

“Serenity let your sister go,” Hollow mentions reading through her book.

“Why should I?” Serenity retorts as she continues to smother her sister with her rear. “She started it by making fun of me when she doesn’t have a great ass like mine!” Serenity boasts puffing her chest out.

“I wouldn’t say that honey,” Hollow points out. “Cath has appeal as a shortstack which in itself is the appeal,” she explains.

“Really does dad like that sort of thing?” Sneak asks as she adds her solution into the milk.

Hollow doesn’t respond instead just closing her book and staring into the void in thought before coming to the conclusion her kin do.

“You don’t know, do you?” Queenie blurts out.

“Of course I know! It should be in my little black book,” Hollow laughs it off in an attempt to save face using her magic to conjure said book before feverishly leafing through it.

“Black book?” Rybbon questions.

“It’s a book mom has to keep notes on dad and everything about him,” Sneak explains. “From favorite foods to preferable sexual positions,” she finishes her explanation.

“Let’s see birthday september tenth no, favorite ice cream flavor cookie dough no,” Hollow mumbles reading through her notes. “Ah sexual kinks preference!” she loudly proclaims reading through them before noticing she does not have it written down. “M-maybe I passed it,” she tells herself as she rereads through but doesn’t find it. “Milfs, bimbos, goths…” she reads through still not seeing it. “Aaaaaaaaaaaaaaaahhhhhhhhhhh!” she screams, throwing her hands in the book.

She takes a deep breath and her eyes dart to the crates loaded on the cart and over to her fellow buglings.

“Okay well clearly I need to test this theory then and get an answer,” Hollow says, unhooking herself from the milk machine. “But I need him to be fully loaded and brimming to burst so I will need your help here girls,” Hollow points out.

“Us?” they say in unison confused.

“Yes we don’t have much time till he gets home from his shift at Flanksworth, so I think with enough effort we use this milk to make some cheese and cream for a nice special lunch for him that will bloat his balls so I can properly test this out,” Hollow explains.

“But wouldn’t that throw off the order?” Sneak protests. “Plus I’d have to undo the solution to turn it back into regular lust changeling milk,” she adds.

“Please if this works the amount of cum and lust your father puts in me I can refill this order in an hour,” Hollow retorts.

“Well what’s in it for us?” Serenity questions.

“I’ll pay you all triple your allowance,” Hollow states blankly to which the girls all stare at each other before springing to attention.

“Reporting for duty mother!” they all salute as Hollow grins.

“Alright then Rybbon heads to the kitchen and begins prepping to make tomato soup, a grilled cheese and some muffins for your father’s lunch,” Hollow orders.

“Yes ma’am,” Rybbon responds before heading out of the barn and into the house.

“Sneak undo your solution from the milk,” Hollow booms.

“On it!” Sneak mentions grabbing a crate and getting to work.

“The rest of you take the milk and make some cheese and cream on the double!” Hollow barks.

“Yes Ma’am!” They respond by scrambling to work grabbing the equipment they have to make said items.

“Finally air!” Thunder Cath exclaims breathing in fresh oxygen having the dump truck of an ass Serenity owns off her face.

The buggos go to work making the requested ingredients from the milk they were supposed to deliver, half working on making delicious cream and the other making some rich cheese.

They soon begin carrying it all inside where Rybbon is hard at work making a tasty lunch for her father that will fill his nuts up with enough for Hollow to have more than her fill of fun. Quickly whipping up a rather creamy tomato soup with some well grilled cheese and delicious chocolate chip muffins as a desert.

“All done mother,” Rybbon mentions, wiping a bead of sweat from her brow and puffing her chest out at the fruits of her labor.

“Good work Rybbon,” Hollow praises her daughter.

“Daddy is inbound, he's coming up to the door!” Serenity exclaims looking out the window.

“Alright girls everypony act natural!” Hollow orders, to which they all scramble to look normal.

In no time at all Magma soon walks in and is greeted by Hollow and his kin to an overly suspicious greeting home.

“Uh hey…” he responds, taken aback by the surprise greeting.

“We all made you a tasty lunch for you sweetie,” Hollow guides him to the hot and fresh meal.

“Oh… you all shouldn’t have,” Magma says as he is soon bombarded by hugs from his kiddos.

Eventually after getting free Magma sits down and goes to town on the lunch enjoying the tasty meal unaware of his sack rumbling as the effects of the changeling milk goes to work on his body building up plenty of love liquid in him. They slowly start to swell, having been emptied due to his long shift at Flanksworth not causing his reproductivity to quadruple and work overtime to make more nut butter.

Soon after Magma finishes his meal letting out a loud burp to signal his approval of the lunch’s tastiness.

“Deeeeelicious!” he exclaims as he pats his stomach and stretches his limbs. “Think I’m gonna go take a shower, I worked a long shift today,” he adds getting up and heading to the bathroom not noticing his balls have tripled in size from his excess cum.

After hearing the door to the bathroom close Hollow smirks and heads after him.

“And that’s my cue, clean up this mess girls and I will pay you once I’m done,” she instructs them giddy with excitement.

“Will do!” Sneak answers.

“Hey these muffins are really good,” a voice mentions from the kitchen drawing the attention of the changeling females who soon have an expression of dread on they’re faces.

“Ditto chocolate chips is the best!” Yubie exclaims in agreement with his brother Hidden Heart as they both chow down on them unaware of the effects that will befall them.

“Should we tell them?” Queenie asks.

“No just get them to the barn,” Serenity adds. “Come on you two,” she says to them as they all grab and drag them away.

Near the bathroom Hollow listens in and hears the sound of the shower turn on and a grin spreads across her face. Lighting up her horn she is engulfed in silver flames as her transformation magic takes place shrinking herself down going from a five foot nine to three foot five replacing the lost height by thickening her thighs, rump and hips. She giggles to herself as the magic ends and she admires her temporary new body before reaching up and opening the door.

Instantly she is greeted by the heat and steam from the shower seeing Magma stark naked washing his body with his hunk of meat swinging between his legs along with his now beach ball size nutsack causing Hollow’s eyes to remain deadlocked on it. Licking her chops she saunters over and opens the shower door drawing his attention.

“I should have… huh?” he states in surprise at her new form.

“What do you think of my shortstack look?” she asks quickly, moving her head as his cock jumps to life in the blink of an eye now noting that he definitely likes shortstacks. “Looks like you approve heavily huh?” she giggles while hefting his rod with both hands due to how short her arms are and how much more of a monster his dick looks with her height reduced.

“What brought this on?” he asks his wang pulsating in time with his heartbeat in excitement.

“Oh nothing, just wanted to give you a nice welcome home present,” she responds with a sultry tone.”So why not have some fun with this new body of mine for the time being,” she adds. “DO whatever you want to me,” she finishes turning around and shaking her butt at him.

“Okay but you asked for this,” he responds looking like the cat that ate the canary as he grabs her by the hips lifting her and spearing his monster dick deep in her wet cunny, a task that is aided by his meat being wet from the shower and how wet Hollow was.

Hollow yelps in surprise his cock bulging through her stomach outlining how hung he is but luckily she made sure her body is super stretchy for him as he begins to pound her hole.

“Holy shit…” she moans out her eyes crossing as he loses her mind from pleasure of him ravaging her pussy holding her up to his crotch level and only allowing her to clamp down his schlong and gushing juices all over his swollen sack. Getting washed away by the hot water beating down on them adding to the appeal of the steam fogging the glass of the shower.

“Shit your so tight… gonna cum!” he announces as his balls tighten and his cock unleashes a geyser blast of his seed deep into Hollow’s stretched and molded snatch instantly bloating her out like a living condom feeling his spooge slosh around as he continues to jackhammer his hips into her slinging his dick as fast as he could desperate to empty all the cum out of his nuts. Her massive G cup melons swing nearly slapping her in the fast due to the speed feeling his baby batter drip out of her around the plug that is his bitch breaker with his widened flare.

“Unf unf my balls feel so full… gotta dump all this cum…” he mutters to himself his hips still thrusting burying his dick deeper in her love tunnel, her blue tongue falls out as her silver-gray eyes cross as she creams herself on his red tallywacker. His nuts keep slapping against her as he fires off another creamy load from his love rocket that continues to delve deep inside her, further expanding her belly but reducing his balls size as she soon finds herself feel even more fuller not at all considering adjusting her body to digest the massive amount of cum she is filled with like a cream puff. He still does not slow down and continues to use her like an onahole, a stray thought crosses her mind thinking ‘maybe I shouldn’t have used all that milk…’ she wonders.

Hours pass of intense shower sex with Magma having blown seven more loads as he howls to the sky and shoots out number eight before exhaustion takes him and he falls back against the wall and slides down taking Hollow with him as she is still firmly impaled on his pole. Sleep takes him as Hollow pants and drags herself off his dick a task that is difficult considering her cum packed belly is touching the floor but she is able to pop free of his flare with a wet pop and letting the waterfall of cock cream flow free. She then uses her magic to restore her height to normal and pants heavily as she gains her composure.

“Well… I did ask for it,” she pants to herself feeling strength get to her legs again.

She stands up patting her belly and turns off the water and decides to let him sleep this off as he sits surrounded by water going down the drain mixed with spooge.

As she walks out of the bathroom and through the house outside to the barn leaving a long trail of cum on the floor she passes.

Swinging the barn door open she is greeted to the sight of Serenity, Rybbon and Queenie working hard to try and milk Yubie and Hidden Heart who’s balls have bloated to the size of watermelons and they’re dicks firmly attached to cock milkers.

Hollow shoots an inquisitive look to Sneak who gulps at first.

“They ate some of the muffins that were for dad,” Sneak answers instinctively.

Hollow nods and walks back over to her breast milker before hooking herself up and turning it on. She reaches over and grabs her black book and conjures a pen into her hand.

“Shortstacks are a yes,” she writes down with a smug grin as she begins digesting his seed.
