Megan knew from the glint in her friend’s eye that this gift was a joke. They did that to each other sometimes, got each other things that they probably had no use for but were amusing in their own right. Taking the wrapped box from her friend, she said, “Thanks, Erica, I can’t wait to see what it is.”

Unwrapping and opening the box, Megan pulled out a black bra, something she could have used… if it wasn’t four sizes too big. Megan tried her hardest to laugh. Erica knows I’m insecure about having small boobs…

Megan looked up at her friend’s beaming face. “Well? Do you like it?” Erica asked.

“It’s… great, Erica, thanks.” She put the bra back in the box. “Look, I’ve gotta get home, I just remembered there’s something I have to do today. I’ll text you later.” With that, Megan left her friend’s house for her own.

At home, Megan held up the bra, examining it. “Why did she think getting me a DD cup bra would be funny? I couldn’t fill this thing out in a million years! And she knows that I’m sensitive about my boobs being small!” Still looking at the oversized bra, Megan was suddenly struck by the desire to try the bra on- despite knowing it was way too large for her small chest. She slipped her t shirt and lacy white bra off and pulled the straps of the new bra over her shoulders. Hooking the back, Megan observed herself in a mirror. I wish my boobs were this big. Or bigger… Oh well. I should probably put my clothes back on and stop fantasizing.

Megan felt her breasts start to tingle. She gazed down at her chest and gasped. Her former A cups were growing, slowly taking up more space in the bra. “Oh my god!” she nearly shouted. “The bra is making my tits grow? Is that even possible?”

Her breasts soon filled the bra cups. “This feels so good,” she said. Megan expected the growth to end when she filled the bra, but to her surprise and delight, her boobs kept swelling, beginning to flow over the tops of the bra cups. Soon, they were pushing out the sides and the bottom. I should try to get this off before it snaps. Reaching behind her, Megan tried to pull the band enough to get the clasp undone, but her burgeoning boobs were exerting too much force for her to get enough leverage. Instead, she pulled the straps off her shoulders and stuck her thumbs in between her ribs and the band and tried to push it down off her breasts. The band moved slowly at first, then quickly released its hold on her head-sized tits.

With the sudden release of pressure, her boobs bounded out into the open space, and Megan was shocked as milk shot out of sensitive nipples. I’m lactating too?! She was shocked again to discover that her boobs were still growing, even though the magic bra was hanging down around her waist. Megan quickly unclasped the loose bra and hurried to her bathroom, holding her breasts as she moved. She could feel them pushing more and more into her hands as she walked, her milk dripping slowly from her breasts into her hands.

Once inside the bathroom, Megan kneeled by the tub, letting her huge and still enlarging breasts hang over into it. As Megan’s tits approached the size of volleyballs, the release of milk increased from a slow drip to a steady flow. “Oh, god, fuck, this feels amazing,” Megan said, bringing her hands up to her breasts and using them to massage the milk out faster. Megan lost herself in the pleasure of milking herself, and her boobs kept growing larger and larger. She closed her eyes and felt her hands moving further away from her torso as her breasts steadily swelled, but she didn’t care. She was finally growing the huge boobs she wanted. Megan was originally unsure of how she felt about her new lactation, but the sensation of the milk flowing out of her thick nipples convinced her that it was something that she liked.

Megan’s mind cleared gradually as her lactation slowed and eventually stopped. She stood. Megan opened her eyes and looked down at her chest. She gasped. “I had no idea they had gotten so… huge!” Her breasts were now way beyond the volleyballs she had when she closed her eyes. Now, her huge tits were more akin to basketballs, hanging down to her hips and thrusting out a foot in front of her. They obscured her hips on either side as each was greater than a foot wide. Megan’s nipples had grown as well, the once small nubs having grown much thicker, too big to be proportionate even to her giant breasts. She pinched her shot glass sized nipples and could feel her breasts steadily filling with milk again.

“They’re so big… I love them. Wait until I tell Erica.”
