Bridget waited with her young daughter for her school bus. It was a warm spring day, a Friday, and she dressed lightly in a tank top and shorts. She lacked a bra; her breasts were as perky as before Emily was born. The mother walked her onto the bus and watched as it pulled away. Turning to walk back into the house, Bridget saw her new neighbor walk out to her car. Leaving for work, I suppose, she thought. Bridget had barely seen her neighbor before now; she’d only moved in a few days ago. She immediately noticed her neighbor was beautiful, a moment later, Bridget saw how busty she was. The young woman’s bust was noticeably larger than Bridget’s own D cups. Damn, what are those? G’s? Some girls have all the luck…

She walked back into her home. Emily was on her way to school, Eric had been at work for hours. What’s a young mother to do?

Removing her shirt, Bridget started to get ready to get on the treadmill. She dedicated at least an hour a day to staying fit. Topless, she saw herself in the mirror. For the first time since she was a teenager, Bridget felt like her breasts were too small. She gently played with them, examining her figure in the mirror. The girls are hardly small, and Eric has never voiced any displeasure with them. Why do I feel like this now? Because some girl in her twenties has big back-killing tits?

During her run, Bridget kept getting distracted by the bounce of her boobs. Wouldn’t it be kind of fun, though, to be a bit bigger? Especially if I could surprise Eric… She smirked wickedly as she got off the treadmill. Bridget pulled her sports bra off and looked down at herself. “Implants are so… unnatural. I wonder if there’s a real way to make my boobs bigger.” She examined her sports bra. “This thing is getting kinda beat up,” she observed. “I should probably get one to replace it. Let’s see what else is on the agenda today.” Bridget walked downstairs to look at the calendar in the kitchen.

“Hmm. Emily’s going right from school to a friend’s house and spending the night there, so Eric and I will be home alone. Maybe a new sports bra isn’t the only thing I should pick up.”

At her local department store, Bridget browsed through clothes. She’d already picked up a new sports bra; that was the easy part. She looked at a few shirts, but nothing was really sparking her interest. Then, she saw it. A plain white v neck, very basic. Something about it… drew her attention in. Bridget picked it up, determined to try it on, at least. She loved v necks, loved showing off some cleavage.

Inside the fitting room, Bridget stripped off her own t shirt and tried on the new one. Examining herself at all angles, Bridget didn’t notice as her cleavage subtly bulged out deeper. “I look damn good in this,” she stated. This with just panties… a nice greeting for Eric, I think. She took the shirt off and refolded it. After paying, Bridget adventured back home.

Finally home, Bridget decided to pamper herself. How often did she and Eric have a child-free house, anyway? She took a long, hot bath, making sure every inch of herself was scrubbed clean. By the time she was done and dried off, Bridget spied the clock. Three thirty already? Won’t be long ‘til Eric’s home! She pulled a lacy pair of underwear on and admired herself. Pretty damn hot for a mother, she thought, even if I am only 36…

Bridget grabbed the shirt out of the bag the cashier had put it in with her sports bra. She pulled the tag off after reading it. “Expansive,” it read. “Never heard of that brand, but it fits great, so who cares?” She lounged around in her lingerie and v neck, waiting to hear Eric’s car pull in the driveway. She zoned out watching whatever daytime TV had playing, nothing worth paying attention to, really, but Bridget didn’t have anything else to do. One show finished, and Bridget sat up to adjust her position, but something was immediately wrong. Her hands shot up to her chest and confirmed her suspicions- her boobs were bigger!

Looking down, Bridget was amazed to see two cantaloupes stretching out her shirt instead of her normal D cups. “Oh my god!” she exclaimed. “These are huge!” Squeezing her breasts, bolts of pleasure shot through her. “And they feel… damn good! Eat your heart out, neighbor girl!”

Her boobs continued to enlarge, overflowing her hands. “How is this happening?” she asked to the empty room. Bridget held her tits in her hands as she marched back upstairs to her room. She rummaged through things, looking for the tag.

“Expansive,” she read. She flipped it to the other side. “Enchanted to make your boobs grow! Extra effects based on color!”

“Well I’ll be damned. This shirt is making my tits bigger… And extra effects? It doesn’t say what those are.” Bridget gripped the bottom hem of the shirt and pulled up.

The shirt wouldn’t budge.

“Oh god,” she whispered. Resigned to her fate, Bridget stared at herself in the mirror. Her boobs were bulging out as the shirt constricted around them. They grew into head-sized mounds as Bridget noticed a fullness within them. She experimentally squeezed them and felt an intense amount of pleasure as milk flowed through her sensitive, growing nipples. “Am I…? I’m lactating… from a white shirt. Clever.” Bridget continued to massage her burgeoning boobs, moaning as her milk was happily expressed. “It feels so good,” she mumbled as she fell on her knees, then onto her back. “I just wanna lay here… and grow… and lactate…”

She proceeded to do just that, the shirt’s magic still working on her tits. They inched larger, weighing down her torso. Her milk soaked into the shirt, making it transparent, her fattening nipples pushing into the fabric. The cream started to leak out of the shirt and onto the floor as pleasure started to take over Bridget’s mind. She only had one thought: she needed more. Her hands crept under the hem of her shirt, and she smiled dreamily from being able to get them there. Meeting her nipples, her hands started to pinch and tug on the nubs.

Her lactation intensified, a pool of milk forming around her on the carpet. Bridget didn’t care that she was staining the carpet, she only wanted to express more- as much as she could. Her v-neck stretched as her tits began to overwhelm it, the volleyball sized masses making the threads pull apart. “Grow,” she mewled. Bridget’s body obeyed. Her boobs readily plumped up to more unbelievable sizes, continually gaining mass.

Bridget was temporarily gone as she grew and grew, her mind now overwhelmed with the sensation of lactating. She climaxed and the crotch of her shorts dampened. She couldn’t focus on her nipples anymore and her hands relaxed, but her tits kept pumping out her milk. The intense pleasure made Bridget fall unconscious, still growing, still flowing.

Just past five, Eric pulled into the driveway. He had gotten to leave work early and was looking forward to spending the night with his wife. He was surprised to not find her in the living room, and headed upstairs to look for her. “Bridget? You up here?” he called. At the top of the stairs, he saw her standing in the doorway to their bedroom. His jaw dropped.

She was naked—no, that wasn’t entirely true, a white t shirt was pushed up over her breasts—and letting her huge breasts sit on display. They were gigantic, figure-defining, similar in size to basketballs. Topped by huge nipples, Eric noticed the white fluid leaking out of them. “Bridget..?” he asked. “What happened?”

“I’ll explain later,” she purred. “First- sex, now.” She pulled him into their bedroom and onto their bed, barely giving Eric a chance to take his clothes off before shoving a nipple into his mouth. “Please,” she begged. He sucked, and her breast eagerly released a torrent of milk into his mouth. She helped him get his pants and boxers off, then guided his stiff cock into her. Bridget moaned, overcome with sensation, as he pushed himself into her over and over and greedily suckled her milk out.

“Mmmf,” she moaned, “Do you… like… them?”

Eric released her nipple only long enough to answer. “God, yes, you’re so fucking hot, Bridget.”

She smiled through the moans. “I’mmhmmmmm glaaaad, hun. Oh fuck, that’s good.”

When Eric’s hand started to milk her other breast, Bridget couldn’t control herself anymore. She came nearly instantly and spasmed underneath her husband. Eric quickly followed suit, his ejaculate flowing into her even as Bridget continued to express milk. He released her nipple and rolled to lay next to her, her huge tits squishing between them.

“So…” he gestured to her body.

Bridget smiled. “I bought a new shirt today,” she said, indicating the soaked, rolled up shirt pushed up above her boobs. “Turns out it was magic and made me grow huge tits. I’m sure you’re crushed.” Bridget smiled as she teased her husband.

He looked again at her figure. “I’m finding it hard to be disappointed right now, babe.”

“You and me both.” She smirked. “Round two?”

“I’ll go as many rounds as I can,” Eric said, returning the smirk.
