Maddie was, uncharacteristically, a little nervous. Her first male customer stood in front of her, and she was about to cast a spell she had never done before- and one she couldn’t test on herself. It’s just a dick, Maddie. It can’t be THAT complicated. The guy in question, Scott, felt a little awkward. “Maddie? What should I, uh… be doing?”

“First off, let’s see, uh, you just want a bigger cock right? And you said double in size?” He nodded sheepishly, thumbs in his pockets. “Alright, well, I’m gonna need you to whip it out then, so I know what I’m doubling.” Scott blushed a deep red, and fumbled around with the button of his jeans. After a few attempts, his jeans parted, and he pulled himself out.

“I need you hard, too, so…” The witch snapped her fingers, and instantly her sweater and bra transformed into a tight and thin white t shirt and bikini- clothes that did nothing to hide her plump nipples. She smiled at him as he rose to attention; as he hit fully erect, Maddie raised her eyebrows in surprise. “You’re pretty big to begin with, huh?”

“I… guess… it’s, uh… seven and a half…”

“I’d say that’s big, dude. Anyway, let’s get started.” The silver-haired woman snapped her fingers again, and in a few moments, Scott’s eyes were bulging as his cock was sprouting longer before his eyes.

“Holy… oh my god… I-”

“What, didn’t think I could actually do it?” Maddie smirked.

“No, I just… it’s getting so big…” By now he’d put on a couple more inches, and a decent amount of thickness. He tried to wrap his hand around it, but couldn’t get his fingers and thumb to touch. Scott stared, dumbfounded, as he stretched out inch after inch, the head of his cock getting further from him and closer to Maddie. He absentmindedly began stroking himself up and down, and a slow exhale escaped from him as an unexpected increase in sensation made itself known.

Maddie bit her lip; this was turning her on more than she thought it would. She balled her fists, determined to ignore it, but watching the growing cock in front of her was too tempting. In short, she was mesmerized watching him grow; her eyes only moved to notice his balls swelling a little to stay somewhat proportional. Luckily for her pride, Scott was too lost in his own world to notice her open mouthed staring.

As he neared the end of his growth, with his cock over a foot long, Scott summoned all his willpower to resist finishing, and released his cock from his hand and clenched his fist to stop himself from grabbing it again. Maddie brought herself back to reality as she realized he was done, although she reached a hand out towards the fifteen inches of Scott.

“Maddie- what are-” he began.

“I have to, ah, make sure it still works! It’s my first time doing this sort of thing!” She stroked him, gently, marveling at the disparity of her dainty hand against his meaty dick. She gave up the charade and dropped onto her knees; she wanted to make him cum, and she didn’t feel like waiting. Despite her wariness of trying to fit this thing in her mouth, Maddie dove forward and wrapped her lips around Scott’s cock, just barely getting the head in. She bobbed her head while running her tongue around him, and she redoubled her efforts after hearing him moan.

Maddie had a quick idea, and snapped her fingers again. She felt her lips thicken around the shaft in her mouth, letting her get a more complete seal on him. She brought both her hands to his cock and began to stroke the length of him she had no hope of reaching with her mouth. As Maddie worked him, she felt his knees tremble, and knew he was close. She pushed just a little further down on him, the tip of his cock tickling her throat before he grunted and a wave of cum shot into her mouth.

Maddie did her best to swallow his tide of ejaculate, but his pumped-up balls had more than she could contest with, and some leaked out her mouth and dripped from her chin to her cleavage. She continued through to the end, taking down as much as she could, letting the rest decorate her tits. When Scott was finally done, she slipped his cock out of her mouth and sat on her feet, inwardly proud of herself.

“That was… uhhh…” Scott struggled to find the right word.

“Anything short of amazing, and I’m reversing the spell.”

“No, that was… amazing,” Scott stammered out. “Oh my god, that was unbelievable.” Maddie smiled and licked the cum off her plump lips.

“Anything else I can do for you, Scott?”

A nervous grin crept across his face. “I was wondering if, uh, maybe, I could, uh,” he stuttered, staring at her chest, the thick nipples poking through the fabric of her shirt.

“You wanna fuck my tits, don’t you?” He nodded. “Hmmm… sure. Why not?”

The witch stood and pulled him through the curtain that separated her work space and living space. She collapsed on her bed, huge tits bouncing around in the barely-restraining bikini top and thin shirt. Maddie pulled them off, ignoring whether or not the sperm that dripped down onto her chest while she was blowing him got wiped off. Scott stood at the side of her bed, unable to will himself forward.

“Come on, bud, they’re just boobs. They’re just… really big.” He shook himself out of his reverie and pulled his jeans and boxers all the way off. Climbing on top of her, he was still marveling at the new size of his dick.

“Do you have, uh, l- lu-”

“Lube? Somewhere, but we can improvise.” Snap. Maddie moved her hands to either side of her tits and began pushing them together until, a few seconds later, streams of milk began to leak from her nipples, trailing down into her cleavage. “That should do it.”

Scott gently pushed his cock into the inviting softness of Madeline’s boobies until his pelvis was grazing the bottom of her tits. The head of it just barely poked out the top of her cleavage. “Oof, that really is thick, huh?” Maddie teased, slowly working her boobs together around his penis, squeezing her milk out. He started moving too, pulling out slowly and then thrusting back in, relishing the smooth feel of her lactating tits.

He placed his hands over hers and took control of the action, now pushing harder than she did, and Maddie’s milk gushed out, covering her chest and his cock in the white fluid. Madeline moaned with pleasure, little coos interrupted by deeper growls emanating from her. The witch’s toes curled and her brow furrowed as the sensation of her lactation thrilled through her. The combination of the feelings from his groin and Maddie’s sound effects were working a number on Scott; he stiffened into steel between her tits and pushed one final time into her cleavage. When he peaked, his cock let loose, cum shooting onto Maddie’s neck and face, covering her in white globs, the ropes crisscrossing over her.

Madeline held her eyes shut while Scott’s huge balls emptied for the second time that afternoon, dousing her in sperm. When she was sure he was done, Maddie opened her eyes and licked the cum off her lips before speaking.

“Fuck me,” she whispered.

“Huh?”

“You’ve got me going too much, I need that thing inside me. It’s your lucky day, Scott.”

“But I don’t-”

“Don’t worry about a condom. You couldn’t get me pregnant if we did this all day.” She affixed him with a stare. “Just put your dick in me, already.” Her tone of voice made it clear this wasn’t a request, but Scott wasn’t about to fight her on it. He slid down her torso to her knees, pulling her leggings and thong off on the way. She was already clearly ready to go as Scott first saw her pussy, and an annoyed grumble-moan reminded him of the current impatience of his lover. Scott quickly straddled her and began pushing into her.

As big as it was, she easily accommodated the head of his cock, and he gently thrust into her, inch by inch. “Yes, oh fuck, yes,” she moaned, one arm wrapping around him, shoving his face into her cleavage, the other grasping the mattress underneath her. Scott slowly found a nipple and latched on, making her lactation intensify again. “Oh, goddess, fuck me, yeeeessss.” A sharp inhale escaped her as he nibbled on her nipple and he started milking her other teat.

Scott was bottoming out in her, never pushing in more than she could handle, and Maddie worked her muscles around his cock. Madeline’s words devolved into short gasps and throaty moans as she got closer and closer to her desired climax, and in a few more moments, her entire body tightened around him, her face stuck in an expression of pleasure, until she slowly rode through her orgasm, and her muscles relaxed. Hearing her finish was all the Scott needed to finally shoot his third load of the day into her. He didn’t know how Maddie was sure she couldn’t get knocked up, but he pumped her full of cum anyway.

He tumbled to the side of her, a little out of breath.

“Anything short of ‘the greatest experience of my life,’ “ she panted, “and I’m reversing the spell.”

--------------------------

“I hope you don’t mind if I have a bit of fun this time, Scott,” Maddie purred, already laying on top of him on her bed.

Pulling his eyes from the intense cleavage she was squishing into his chest, Scott shook his head. “Not at all.”

“Alright, well, prepare yourself,” she said, lifting herself up, but not before forcing her boobs into his face. Maddie grabbed the bottom of her shirt and lifted it up, for once not taking her bra with it. “Tell me you love my tits,” she demanded.

He smiled. “I absolutely love your tits.”

“Tell me you want them… bigger.” Maddie unclasped her bra, letting it fall off and tossing it onto Scott’s face.

“I wanna be fucking smothered by your tits!” He pulled the undergarment off himself and let it flutter onto the floor.

Madeline smirked as she noticed his eyes were helplessly locked on her stiff nipples. She slid back, down his legs, pulling at the fly of his jeans. Yanking them off, Maddie aggressively pulled his boxers off too, freeing his huge dick. “Good boy,” she commented on seeing him hard.

“I’m gonna titfuck you within an inch of your life,” Maddie said. “You grab the lube, and I’ll do… something else,” she finished, smirking. Scott shimmied over and grabbed a bottle, popping the cap open and working it around his cock.

The witch snapped her fingers, letting off a spell and hitting Scott with it; he felt the energy suffuse him immediately. “You first,” she laughed. “I want you to actually see what happens!”

Looking down, he was momentarily confused because his dick wasn’t growing at all- but looking beyond it, he saw what she was doing. Scott slipped a hand down, palming one of his enlarging testicles. Originally the size of softballs from his first experience with Maddie’s magic, they were rapidly growing larger, filling up his hand. “Maddie- wh-”

“Gigantic tits call for lots of cum, don’tcha think? I’ll put you back to normal when we’re done.” She watched his growth taper off, his balls now each around the size of a ripe cantaloupe. “My turn.” Maddie snapped off another spell, targeting herself this time. Her eyes fluttered closed and she smiled as the rapturous nature of her breast growth began; Maddie’s basketball-sized tits swelled larger and larger, quickly becoming large enough to settle on Scott’s legs.

“Isn’t that nice?” the witch asked as she settled her colossal breasts around his erection. Maddie snaked her arms under her boobs and lifted them as best she could as she continued to grow, steadily getting her whole body into the motion of sliding her tits up and down his length. Beyond beach balls she grew, smothering Scott in her warm, inviting flesh.

“Fuuuuuck, Maddie,” he moaned, his dick lost in all her cleavage. He gently squeezed handfuls of tit, almost not believing how much boob Maddie now had. As she grew larger, more of Scott was buried underneath her bust, and Madeline eyed him needily.

“Play with my nipples,” she commanded, her breasts now so large that she couldn’t lift all their mass. Scott obliged, grabbing onto the nubs as the inched ever closer to his face. He gently pulled on them, working them harder and harder until they nearly filled his hands. “Oh, fuck, that’s it, Scott, goddess, you’re so good at this…”

“Unnngggggh,” he moaned, his hips bucking into Madeline’s fat tits. “Maddie, I’m gonna-” he let out a long exhale- “I’m gonna cum!”

“YES!” she screamed, eager for it. “Fucking douse me in it!”

Scott groaned; the size of his dick and balls meant it took a few seconds for him to fire, but when he did, it was a veritable eruption of cum. With his cock still hidden in between her tits, the first load didn’t even escape her cleavage, the canyon now slick with sticky ejaculate. The following blasts, however, were like white, pasty fireworks going off. Scott covered her in cum, ropes criss crossing over her tits, a few more flying up to her hair and face.

The witch quietly watched him recover, not yet cleaning up any of the jizz. When he finally looked up and opened his eyes, she smiled at him. “Want a picture?” she asked, waving her hand and pulling his phone to it. “But if I find this on the internet somewhere, you’d better start running,” she warned. “Or you’ll need a microscope to find your dick.”

“Don’t worry,” he said, snapping the picture while she made bedroom eyes at him. “It’s going in my secure folder and never coming out.” He took another while she wiped some cum off her tits and sucked the fingers into her mouth.

“Good. Now,” she said, licking some of the cum off her hands and face. “I hope you didn’t think I’d let you go that easily.” Maddie wiggled her hips forward, enlisting help from her fuckbuddy to lift her boobs up while she rose almost to her feet, aligning herself over his thick cock. “The end of this is gonna be an experience,” she joked before sliding down. “Oh, fuck, how do I always forget how big it is…”

Maddie slowly eased herself down his mast, bottoming herself out and slowly bouncing- her tits still resting on his chest. The witch worked him expertly, tightening at just the right times, gyrating her hips. She moaned while he played with her nipples, working wonders on the stiff nubs. “Mmmmm… if I was lactating right now, you’d be drowning…”

A stronger-than-usual bolt of erotic electricity ran from her nipples to her pussy, and she twitched and tumbled down even further, filling herself up entirely with Scott’s dick. The downstroke was all he could take, and he was again letting loose- this time inside her pussy. “Ah, oh, oh fuck, oh fucking god, there’s so much!”

Scott’s dick was pumping cum out, way more than could fit inside her- especially with how stuffed full of cock she was. Ejaculate leaked out as Maddie’s face expressed her purest bliss, her tongue lolling out, eyes crossing, cheeks blushing. “Uu- uguuuu~!” she screamed. “Oh god, I fucking love your dick!”

-----------------

“So, you’re moving tomorrow, huh?” Maddie asked as she brought Scott up to her bedroom one last time.

“Yeah. Got everything packed up already, then it’s time to drive all the way out to Oregon.”

The witch closed the door behind them. “Well, guess I’d better get all the mileage I can out of that dick, huh?”

Scott groped her from behind, and Maddie moaned aloud. “And me from these tits,” he teased.

“Mmmm… where am I gonna find someone as good at fondling me as you?” Maddie joked. She turned to face her friend-with-benefits and smiled devilishly. “With one last night of magic… want anything bigger?”

“I wouldn’t complain.”

“What about a new spell to test?” She pulled herself out of his arms and started stripping her clothes off, giving Scott a little show as she did.

Scott folded his arms. “What’s it do?”

“Gives you another pair.” Maddie finished undressing, and tossed her thong on top of the pile of clothes.

“Hmmmm… alright.”

“Fantastic,” she said, dropping onto her knees and yanking him half-naked. His dick was mostly hard at this point, and Maddie took it in one hand and worked him up, smiling as he rose to full attention. Once he was hard, Madeline snapped her fingers and flowed her magic into him. Scott’s eyes glazed over from the pleasure of his growing cock, and the witch continued to tease him with a hand.

Longer and thicker he grew, leaving his old fifteen-inch size in the dust. Maddie eventually had to support him in both hands and shuffle backwards. As it finished growing, Maddie let his cock rest on her face, and she kissed and licked the underside while she moved to cast her second spell. She held his balls in her hands and cast her spell, and she instantly felt another pair in her hands, and all four swelled a little larger.

Maddie pulled back and looked at Scott’s new package. “This thing is a crime against nature and I cannot wait to put it inside me. Which reminds me...” She shuffled over to her nightstand. “Portia wanted me to test a new potion. With luck, you’ll be sliding into me without any issues.” She winked at him and giggled as she saw a dollop of precum leak from the head of his dick. Maddie downed the potion in one go and felt heat envelope both her throat and her pussy.

The witch slid back to her boytoy. “Time to make you cum your brains out one last time,” she purred. With that, she slid the head of his massive cock between her lips. As she pushed further down, her jaw opened as wide as possible, and he still barely fit. Portia’s newest potion was clearly working, and Maddie swallowed more and more cock. Her throat bulged with its passage, but she kept on, not letting herself stop until she pressed her lips to his pelvis.

She moaned from the thought of how much dick was stuffed into her throat, and slowly drew back to bob her head on the end of his cock. Scott moaned and grunted, wanting to hold onto Maddie’s head, but he couldn’t reach- Maddie had doubled his size again, so she was much too far out of reach.

Scott stumbled backwards; he couldn’t keep himself on his feet anymore. Maddie pushed him back until his thighs hit the bed, then let his cock slip from her mouth as she followed him onto the mattress. The duo shuffled back before Madeline engulfed his length in her cleavage.

Overcome by his lust, Scott flipped them over, and grabbed a strong hold of her tits. He pumped back and forth between her boobs- the only lubrication he needed was the copious amount of pre almost gushing from his dick. Maddie’s boob valley was slick within seconds, and he was so big that she couldn’t hope to contain all of him in it.

Maddie felt his quartet slapping against her bosom with each thrust. She thought dreamily about the four nearly cantaloupe-sized cum-factories, and how much spunk she’d be covered in at the end of this. She leaned forward and let the head of his dick go in and out of her lips, adding another layer of pleasure to his already mind-numbing experience.

She could tell he was close, his thrusts became shorter and faster, his breathing heavy. “Come on… come on… come on… cum on me!” she enticed. “Blast it all over my face!”

Scott couldn’t take any more, and pushed forward once more and spewed cum, the first load drenching her face in sticky whiteness. He pulled back, still blasting off, and pounded into her pussy. The potion was a complete success, and Scott slammed in to the hilt. Maddie gasped and moaned with the sensation of a thirty-inch cock inside her. Scott’s first orgasm ended, but he was still hard, and continued sawing away in her gushing pussy.

Her tits bounced and wobbled with the roughness of the fucking. She held on to them and clamped down on him, moaning nearly constantly. “Your m-monster cock feels so- so gooooood,” she mewled. “I want you to f-fuck me… forever…”

He grabbed onto her hips and pounded even harder, driven on by Maddie’s delirious fantasies. In just a few more seconds, his second orgasm hit, and he released a torrent of cum into the witch’s desperate wetness. Jizz gushed from between her thighs and splattered the sheets below them, and Scott ceased his motion but held her down on his pelvis until he finally stopped cumming.

Scott slowly pulled back and looked again at his twice-enhanced cock; it’s previous erection-length was now what it looked like soft, and his four testicles were the largest on the planet, he assumed.

Maddie slowly came back to reality. She stretched and wiped some cum off her face and swallowed it. “I have a gift for you,” she said. The witch slowly stood, and wobbled, bow-legged, to her dresser. She took a box from atop it and handed it to her fuckbuddy.

He pulled it open to find a plain black bra--clearly one of Maddie’s--inside. “Uh..?”

She smiled. “It’s enchanted. Give it to a nice girl out west and she’ll get a figure you’ve come to love.”
