Three friends were home from college on winter break, hanging out while one girl's parents were on vacation. They sat on the floor, just talking the hours away. "Check this out," Gail said, holding up a bra to show her two friends. "I accidentally picked it up last time I went shopping."

"I don't get it," Jessica squinted at the bra. "Why does it look so strange?"

Indeed, the bra did look kind of strange. The cups were softer, and had hooks at the top to expose a breast. "It's a maternity bra. You know, for when you're knocked up. The cups unhook so you can get your tits out to feed your kid," Gail replied.

Bethany chimed in. "Why didn't you return it? You doing have any big news to tell us, do you?"

"That's the weird thing. It must've been accidentally put back with the regular bras because I have no reason to be looking at maternity bras. But when I went to return it the barcode didn't come up on the register. So now I'm kinda stuck with it." Gail didn't expect the bra to be enchanted.

"Does it at least fit? It might be handy as a backup," Jessica suggested, always trying to be helpful.

"I never tried it on, actually. Why bother, I figured, I'm not gonna squeeze one out any time soon. But you have a point, Jess," Gail said as she dropped the bra and pulled her t shirt up, exposing her plain white bra. "You girls don't mind, right?"

They both shook their heads. They were roommates in college, and saw each other topless on a nearly daily basis. Gail was cursed with being average, she thought, with straight brown hair and hips and breasts that weren't too large or small. Gail removed her bra and tried on the new one. Her B cups sat loosely within it. "Looks like I won't be a mom any time soon. Jess, you're the one with the boy-catching tits, why don't you try?"

Jessica shrugged and held out her hand foot the bra. She was the bustiest of the three, boasting DDs on her thin frame. Her friends believed she could be a model if she didn't have such big boobs. Long, curly blonde hair surrounded a classically pretty face, and aside from her chest, her proportions were lithe. Gail slipped the bra off and handed it to Jess, who quickly tried it on. The opposite of Gail, her boobs overflowed the maternity bra. "Too big, as usual." Jess grumbled.

"Give it here, I'm between you two anyway," the red headed Bethany commanded. Bethany had a figure similar to Gail, but more filled out. Just as she expected, Bethany's breasts fit comfortably in the bra. "Looks like I'm the winner. What's my prize?" Bethany joked.

"Hm. The bra?" Jessica suggested.

"Big milky mom tits?" Gail said.

"Ha ha, Gail. You're hilarious." Bethany stripped the bra off. "I guess I'll keep it. Might as well, since you can't return it." A confused expression came over Bethany's face as she tried to hook on her own bra.

"What's the matter, doll face?" Gail asked her.

"This is gonna sound really weird, but... my bra doesn't fit anymore."

"What?" Jessica asked, confused.

"My boobs are too big for my bra!"

Looking at them, it was clear Bethany's breasts were bigger. And then, it was more apparent that they were growing. They were pushing past D cups as the girls watched. Bethany looked up at both of her friends, who were both staring at her tits.

"Oh my god, Jessica! You're growing too! And Gail! We all are!" The other two looked down at their own chests. Each girl had gained about a cup size in a few minutes. The growth seemed to pick up as they noticed it, and their breasts grew, happily plumping up larger and larger. The girls sat there, dumbfounded, watching each other's boobs grow. Minutes passed, and the girls sat in silence, seeing their breasts add inches to their circumference.

Jessica was the first to break the silence. "This is kinda weird but... it feels REALLY good," she said as she brought her hands to her head-sized tits. She massaged them as they continued to grow, the pleasant feelings intensifying.

The other two followed suit. "I didn't want to be the one to bring it up, but yeah, you're right. My tits feel so good," Bethany agreed as she fondled her own cantaloupe boobs.

Gail looked at Jessica's growing boobs, and moved a hand from one of her own to Jessica's. "Damn, Jess, your tits are huge." She made Jessica moan as she roughly played with a tit.

"As if you're one to talk, melon-boobs," Bethany said as she groped one of Gail's breasts. The three of them started to grope and fondle each other's breasts as they continued to grow. Soon they were all large enough that it was hard to tell exactly who was the biggest. Each girl had boobs the size of volleyballs, at least. Jessica was the most sensitive, which put her at a disadvantage in their breast grabbing war, and Gail and Bethany teamed up on her. The other two girls each worked a separate tit, grabbing, squeezing, jiggling Jessica's growing boobs. Jessica fell back to lay on the floor as the pleasure mounted, a damp spot appearing on the crotch of her jeans.

"It's too much, oh god, I'm gonna, I need, in gonna, ooohhhh, I need to..." Jessica didn't finish her sentence before she stuck her hand in her jeans to work her wet pussy. With all three sources of stimulation, Jessica came quickly and came hard. Her legs shook as she rode her orgasm to the end, her friends not stopping their work until it was clear Jessica was finished.

"Damn girl, the boys are gonna love you. Huge, super sensitive tits? You're a walking wet dream." Bethany teased.

"Shut up," Jessica demanded as she pulled her hand out of her pants. Their tits were still swelling, but each girl noticed around the same time that her boobs were feeling increasingly full. "My boobs feel... kinda uncomfortable. Like they're full of something besides boob."

"Yeah, me too. This is weird," Gail responded as their figure-dominating breasts visibly firmed up. "What the heck is going on?"

Bethany eyed the maternity bra. "I think... maybe we should get to a bathroom."

"Uhhh, alright. Sure." The trio marched into a bathroom, the nicest one in the house. Bethany invented in front of a claw foot rub, letting her basketball sized tits hang over the side.

"If I'm correct," she said as she started tugging on her nipples, trying to keep her train of thought as she discovered just how sensitive her nipples had become, "our boobs are full of milk because of that damn maternity bra." Seconds later, she was proven right, as a trickle of white liquid flowed out of her right nipple. The left one quickly followed suit. Her friends followed Bethany's example.

"I never... realized how-hmm-how big my nipples had gotten," Gail said between pleasured moans. "These things are huge, though, and with milk flowing through them..." she trailed off. Each girl enthusiastically milked herself, letting the milk flow into the bathtub. Gail and Bethany finished before Jessica did, and Gail leaned over to whisper something to Bethany, who grinned. Jessica didn't notice until the other two pulled her away from the tub by her arms and pushed her down onto the floor. Quickly, before Jessica could get up, Bethany and Gail latched onto Jessica's plump and leaking nipples.

Jessica couldn't put up a resistance as the pleasure from her tits skyrocketed. She smiled happily as her friends sucked the milk from her tits; it felt even better this time than the first time her friends had decided to gang up on her. This time, she came without having to do anything. Not satisfied with only one orgasm, Bethany and Gail kept suckling from her milky boobs as Jessica's legs spasmed with her unending orgasms. Jessica put her hands on the back of her friends' heads to keep them from stopping until she was dry. Gail and Bethany's stomachs filled with milk as Jessica came and came.

Finally, after what seemed like forever, Jessica's huge tits were empty, and she let her friends detach themselves.

"Huge, sensitive, and full of delicious milk. You're definitely a walking wet dream, Jess." Gail teased.

Jessica glared at her as they stood. "God, just how big did we get, anyway?" They each observed their own tits and each other's. Their torsos were obscured by breast, all the AI down to their hips. Their plump nipples rested a foot beyond their chest, big and stiff. And their boobs were wider even than Bethany's wide hips. Seeing each other from the back, breast flesh was clearly visible beyond their arms.

"So we're gonna need new bras..." Gail said.

The other two looked at her. "Let's make sure they're definitely not maternity bras, okay?"
