“Finally!” Hailey let the front door to her apartment shut behind her as she practically skipped into the kitchen. She tossed her bag onto the kitchen table and pulled out a worn and frayed leather bound book. “I’ve waited so long for this!” She hugged the book to her chest, squishing it between her impressive bosom. She plopped the book down onto the kitchen countertop and began skimming through the pages for a very specific spell this book was said to contain, a reduction spell. Or, more specifically, a spell that Hailey could use to reduce the size of her boobs.

Hailey had been living with macromastia ever since she had hit puberty in middle school. She was the subject of teasing and bullying all the way through high school. Some would even go as far as to steal her bra from her gym locker while in P.E.! She begged her parents to get reduction surgery but they never had the money to spare. Hell, when she graduated from high school she was wearing an N-cup bra that was already a couple sizes too small! And now she was an adult who had to custom order W-cup bras because she couldn’t afford breast reduction surgery either! Not with her student loan payments or her crummy retail job that didn’t offer insurance.

But this! This grimy, dust filled book would be the hero her poor shoulders needed! “Ah-hah! Found it!” At the top of the open pages, in handwritten cursive were the words ‘Reduction Spell’. The pages were a bit water damaged and the ink smudged in a few places but Hailey could make out the important bits of the book. “So the first page is a full body reduction while the second page is a modified spell that targets a specific body part… I think…” Some of the words were illegible but she was certain that’s what it was saying.

She took a step back from the counter and readied herself to cast the spell. Butterflies filled her stomach, she was so excited for this moment! After years of buying ever more expensive bras and having guys ogle her chest she just had to focus on her breasts and chant the spell. She closed her eyes, visualizing her chest as flat as a board and chanted, “Octurum paraz, teresh octura!” An unnatural feeling of force washed over her. She opened her eyes and looked down at her chest but instead of seeing her breasts shrinking, they instead appeared to be growing. “What!? No. No! This isn’t right!” She lifted her head up and looked towards the counter to see that she was now almost eye level with the countertop as it rapidly began to dwarf her. She started to run towards the counter to grab the book but as she took her first step she tripped on her now baggy clothes and fell to the ground.

“Fuck!” Hailey wrestled her way out of her now much too large clothes and once free she struggled to get on her own two feet. Her own breasts, although still the same size, felt much heavier attached to her shrinking frame. She realized what had happened, the spell didn’t shrink the body part you were thinking of it shrink everything but that body part and she needed to get her book before it was out of reach! She trudged forwards, her back bent at an angle as she struggled against the weight of her chest. Once she was next to the kitchen counter she got up on her tippy toes and reached up above her head, the tip of her fingers barely reaching the edge of the book. “Come on! I almost- have it!” Her fingers slipped from the pages as her hands slid down the side of the counter. “Fuck!” She shouted as the sudden change in grip caused her to lose her footing. Hailey fell forward, her bare breasts plapping against the kitchen tile. They bounced underneath her like a warm waterbed as the rest of her body continued to shrink. She was only now about three feet tall yet her breasts were already about to dwarf her.

“No, no, no, no!” Hailey pushed against her tits as she attempted to stand up but she found that her chest was now too heavy for her size. Despite her cries and pleas the spell continued to work it’s magic on her. Even though she was the one shrinking she couldn’t help but compare how big her breasts seemed to objects of her normal size as they rapidly went from ‘mattress’ sized to being larger than a ‘pickup truck’. Her legs lifted from the ground, now dangling from her own breasts by where they attached to her chest. Eventually she found herself resting snugly on top and in between her breasts, her cleavage nestling her tiny body which was now the size of a bottle cap. “Did it finally stop?” She looked to either side of her and saw a sprawling field of her own tit flesh, the size difference nearly incomprehensible to her at her new size. The tile flooring was uncomfortably cold as it sapped the heat from the bottom of her breasts which in turn caused her nipples to become engorged and erect. With her facing towards the now colossal cabinets she couldn’t see any of the digital clocks that were scattered across the many kitchen appliances. An hour and a half later, or what felt like several hours to her, the front door to her apartment creaked open as her roommate flicked on the living room light.

“Ugh! She’s always leaving her stuff everywhere.” Her roommate muttered under his breath as he sat his bag on the kitchen table.

“Hey! I don’t- Nevermind. Nick! I’m down here!” She shouted and flailed her arms as she craned her neck trying to keep him in her sight.

“What do I want for dinner today…” Nick, preoccupied by his hunger, made his way to the fridge and began rummaging through it. Hailey’s voice was inaudible to Nick as her voice had shrunk along with her body. “I didn’t go grocery shopping over the weekend. Hmm…” Nick rummaged some more before pulling out a bag of string cheese from the fridge. “This’ll do!”

“Hey!” Hailey continued to shout up at her roommate in hope that he’d eventually hear her. “You have been stealing my food! Nick!”

She was interrupted by a large object falling mere inches away from the far edge of one of her boobs. “What the-!?” Nick had closed the fridge and turned his attention towards the kitchen, dropping his stolen snack in shock at what he saw. His eyes first landed on the pile of clothes which were haphazardly left in the middle of the kitchen floor but that wasn’t the unbelievable thing. Nestled closely by the base of the counter were two masses of flesh with a tiny, little human laying on top of them. He cautiously approached it and squatted down to get a better look at it. “Hailey!?”

“Thank god you finally noticed me! And be careful with my cheese, you almost dropped that on me! Just grab my book and- Hey!” Nick grabbed the side of Hailey’s breasts and rotated her to be facing him. Her breasts sliding as she was forcibly moved felt uncomfortably odd to her. “Don’t just do something like that!”

Meanwhile Nick was still in shock and awe at what he was seeing. His brain worked overtime to come to a sensible conclusion as his tiny roommate babbled on below him. Her voice was also small, only carrying so far before it was incomprehensible. “What? It’s hard to hear you.” He leaned in closer to try and make out what she was saying.

“My book! Grab it and find a way to fix this!” She pointed up at the countertop, hoping Nick would take the hint.

“Book?” He stood up and looked at the counter where he saw the dusty spell book. He took a look at the open page, the aging page and poorly written cursive made it hard to read but he could make out a few words. “A reduction spell? What is this?” He flipped through a few pages, taking note of the pages titles. “Enhancement spell? Hex of stone? Newt’s blessing?”

Haikey watched as Nick tucked the book under his armpit and walked towards the kitchen table, scooping the bag of string cheese off the ground as he passed it. He opened his backpack and shoved the book and bag of cheese inside before slinging it onto his back. He then turned and began walking right at Hailey. “Did you find the reversal spell? Nick?!” He squatted down with his arms reaching towards her. He slid his hands underneath either of her boobs, pressing his fingers into her sensitive flesh as he lifted her from the ground. “Hey! What are you doing!?” She shouted up at Nick but he either couldn’t hear her or was ignoring her. “At least be more careful! These things are sensitive!” She softly bounced in his hands as he made his way to his bedroom. He shut the door behind him and plopped Hailey in the middle of his bed. “Are you even listening to me!?” Nick took off his backpack and took the spell book and string cheese to the other side of his room to his desk.

Hailey didn’t even bother shouting at Nick, knowing full well that he wouldn’t be able to hear her from this distance. He sat at his desk mumbling to himself while he ate her cheese strings and flipped through the spell book. “Ooh!” She heard him exclaim. She saw him get up, which she hoped was because he was going to come over to her and reverse the spell but he instead began stripping his work clothes off and tossing them behind him.

“Hey!” One of his dirty socks flew over her head, “watch where you’re tossing those!” His pants thudded at the foot of the bed. “What are you even-!?” His boxers casted a shadow over her before they landed directly on top of her. Like a spread net it cascaded above her, its damp and sweaty cloth laying on top of her as it pressed her down into her own breasts. “What the hell Nick! Nick!” She shouted in vain as the stale and musty air swirled around her. His pungent musk nauseated her as she continued to listen to his distant ramblings.

“I can’t believe that worked!” Hailey heard him begin flipping through the book again. It didn’t take him long to find what he was looking for as she heard him exclaim once again followed by the shutting of the book. “Whoops, sorry about that.” The tent of practically toxic yet somewhat arousing air was gingerly lifted from her.

“Took you long enough! What the hell are you even doing!” Hailey shouted up at Nick but as her eyes trailed down to her eye level she found her answer. Nick’s pube covered crotch pointed right at her. His cock was small even though it was erect yet that’s not what she concerned herself with. Dangling beneath his legs were two disproportionately large and swollen testicles, each easily the size of baseballs. “Oh my… Nick?”

“I’m sorry Hailey, I-” He sheepishly scratched the back of his head as he looked down at her. “I, uh… I’ve had a crush on you for a while now and…” He trailed off again, his face a deep red from embarrassment. “Fuck. How do I explain this? Uhm, I have a thing for big tits and uh… kind of have a shrinking fetish and… God you’re so fucking hot right now!” He sat down on the bed and scooped her up in his arms by her breasts once again. In one clean motion he rolled over onto his back and gently sat Hailey breasts first onto his groin.

“Wha- I mean- I’m flattered but…” Hailey sputtered at what Nick just confessed to her as she felt his nub of a dick poke in between her cleavage. It and his engorged testicles felt warm against her bosom but his penis didn’t even make it a fraction of the way through her cleavage. “Can we maybe discuss then when I’m back to normal?”

“I’m sorry but,” Nick grunted, “I really need your body right now.” His dick throbbed between Haileys cavernous cleavage. “Okay, here we go.” He bit his lower lip briefly before muttering, “Entranza decor, gurillum.”

“Wha- what now?” Hailey felt something rise between her breasts. Something that radiated a pleasant warmth until- Right in front of her the head of his cock poked through her cleavage and rose above her. It twitched, its veins pulsing as it shadowed over her like a small skyscraper.

“Fuck~ I can’t hold it anymore~” Nick roughly squeezed his dick with Haikey’s breasts, using them to vigorously stroke his shaft. Each lift of Hailey's breasts smushed her pea sized head into his cock as he pleasured himself with her jugs. “Agh fuck~ Your tits feel so good!” His balls clenched as he was brought to orgasm. Ropes of semen shot into the sky before splattering back down both onto Hailey and her tits. “God my balls still ache~” He set Hailey at the side of the bed facing away from him as he stood up behind her. “Let me make you feel good as well~” He pushed his dick between the underside of her bosom and ran it underneath her adorably tiny body, snaking his penis through her expanse until it poked out on the other side.

“Oh~” Hailey squealed in surprise as his dick was ran underneath her body, rubbing against her crotch. He began thrusting, his hands digging into the sides of her breasts. His shaft grinded up and down on her pussy traveling over what felt like massive lengths of flesh in the matter of seconds. “This feels~ weird~!” Each vein on his cock felt like small hills which pushed harder against her as he continued to pump his waist into the mammaries. Each thrust faster than the last as he used her to bring himself closer to emptying his leviathan balls which slapped against the underside of her tits.

“I’m getting close~ Have you?” He looked down at Hailey who was lying limp atop her chest, incoherent squeals and moans escaping her lips as she trembled on his cock. “God, you’re so cut~!” With one last thrust his cock spurt forth streams of cum onto his bed, his legs shaking underneath him until they gave way causing him to collapse onto his bed. In the morning when the two of them woke up he’d change Hailey back and the two of them would discuss some limits on their spell enhanced sexual life they’d be having.
