Theoretically most difficult part: a Bra.

Rebecca poured over her phone, typing away through google. There was, in fact, a kink shop in town that made custom bras. Their selection showed many, many, many options of normal bras. Granted, they did make big and small, and some of the options seems straight out of sci-fi. Like, built-in nipple vibrators? Adult nursing bras? Rebecca wished she had found this place years ago. But Like, she barely wore bras anyway, just for when she went out. Did they have a lace she liked. They did. If she didn't feel like a freak still, she'd be in heaven. They were even washable with no special instructions. Rebecca dialed the number.

"Hello, welcome to Sinful Bliss Boutique. Your Desire is Our Pleasure." a feminine voice came across the phone.

"Hey, I was looking at your custom bras online, and I was curious just how custom they come?" Rebecca asked, suddenly afraid to be fully honest about what was going on.

"We can do just about anything. What did you have in mind?" The speaker replied.

"Uh, well, what if it was for more than... two... boobs?" Rebecca asked, feeling the weight and ridiculousness of her situation.

"Oh yea, we got all sorts of prosthetics, you didn't find those on the site?"

"No. I-- uh, yes, yes I saw those, that's where I got the idea." Rebecca fumbled, "But no prosthetics."

"Oh, you got your own? Or you want to get a separate set up for the fake boobs?"

"No, look, I just need a bra for six boobs. And they're real, not fake." Rebecca blurted out, then burned with embarrassment.

"Look, this is a judgement free store, you don't need to get defensive about what you're into." the speaker sneered at her.

"I'm not! I just, look, I just need a bra for six boobs, that are real." Rebecca punctuated her sentence with a need to be validated.

"Bring your six real boobs down here for a fitting and I'll get you a discount. Ask for Lindsey." Lindsey said, then hung up the phone. Rebecca shot up in bed, suddenly able to ignore all the extra sensations she was feeling. She stomped down to her car and drove off. She pulled into a gas station and entered the store's address into her phone, pulled a probably illegal U-turn, and sped off.

She couldn't believe she was here. Rebecca looked up at the sign "Sinful Bliss Boutique" in a stylized cursive font, ending with the spade point of a devil's tail. Did she really need to do this? She did, she wasn't going to let Lindsey tell her she wasn't real, or whatever it was she had been doing on the phone. She looked down at herself. She sighed. She did need a bra for all that. All that that was her. She could feel that in all the excitement she had leaked slightly. Hopefully it would make for a better sell. Or maybe she'd have to show this Lindsey person?

Rebecca found herself suddenly inside the store. It seemed pretty empty. The front most shelves were stocked with items that were most presentable if someone walked by and looked in, but past that there were toys, books, lots of leather items, and lingerie of all kinds. Rebecca reeled herself in, she was on a mission to prove Lindsey wrong. She wormed her way along until she reached a hanging sign that read "Fitting Rooms" in that same devilish font from the sign outside. She looked around, there was a set of doors, and a bell. Rebecca rang the bell.

"Hello! How can I help you?" a familiar voice came from around a corner. Rebecca's brow furrowed and her head turned quickly towards the voice.

"Lindsey?" Rebecca said

"You... know me?" Lindsey said. She was shorter than Rebecca, significantly. Her curly brown hair was resting on her shoulders that framed a narrow face and brown eyes. Lindsey's eyes narrowed, looking over Rebecca in confusion. "You're the person that called about the custom bra?"

"Yes." Rebecca replied, feeling smug. Obviously, Lindsey saw how serious she had been now.

"So I guess you're already wearing the prosthetic?" Lindsey asks, getting a few measuring tools.

"No, like I said, they're real." Rebecca replied, putting her hands on her hips, "Do I need to prove it to you?" her voice cracked with exasperation.

"I already said you don't have to get defensive, but I guess if you want to, go ahead." Lindsey sighed, rubbing one of her temples for a moment, then crossing her arms. Rebecca stared at her for a moment, not sure exactly what to do. Was she going to flash her? She hooked the hem of her shirt under her lowest breast and lifted it, trying to make sure her nipple stayed covered, while showing her waist. Lindsey's eyes widened.

"Lemme see your neck." Lindsey said, stepping close to Rebecca. Rebecca tilted her head and Lindsey gasped, "They are real?" Lindsey blushed slightly.

"Like I had been saying. So I get that discount?" Rebecca smirked, finally vindicated.

"Y-yes, of course, I'm so sorry, ma'am. Let's get you sized right away." Lindsey stammered, grabbing a tablet and ushering Rebecca into a fitting room; it was a modest sized room ,meant for just two people, a tall mirror adorned one side, and a bench was on the other. "Uh, so let's see... uh, okay, I'll just note everything down and work it out later. Can you remove your shirt?" Rebecca did as requested, smiling as Lindsey's eyes darted between the six dark nipples. Lindsey paused, "Do they, are they all..."

"Yup, all six of them." Rebecca haughtily, she lifted one of her uppers one and a middle one and squeezed them both, releasing a gentle spray from both of them. Lindsey blushed a little more.

"O-okay, uh, let's get started." Lindsey composed herself, and started measuring, Rebecca cooed softly as the cool measuring tape met her skin. "That pair's an F, that pair is also an F, and damn, all six are F's." Lindsey said, setting aside the measuring tape. "Alright, uh, we'll get some drafts made and sent to you."

"Oh, can I get in the nursing features? I plan on doing a lot of milking in the future." Rebecca said, cupping a breast and rubbing another.

"Of course." Lindsey said, typing in some info on her tablet. She handed the tablet to Rebecca, who entered contact information and some other details for the order. "Is there anything else?"

"Yes, I was curious if I could go ahead and give you a tip?" Rebecca asked, tilting her head slightly and shaking her shoulders gently.

"No, you can't tip me directly-- unless you mean... milk?" Lindsey dared to ask.

"Straight from the tap, if you want it." Rebecca smiled. She **** herself to hold it as she worried she had flown to close to the sun. Lindsey's eyes flicked to each of the six milky udders in front of her.

"Yes. I'll drink some." Lindsey said softly, without making eye contact with Rebecca. Rebecca stepped over to her, Lindsey's face suddenly in the middle of all her boobs. Lindsey took a step back and sat in the bench, then beckoned Rebecca closer. Rebecca moved in, pressing her boobs around Lindsey's face. Rebecca let out a soft gasp as Lindsey started drinking from one. Her mouth felt heavenly. It felt right, to Rebecca, she should be having people drink from her breasts. Rebecca gasped again as Lindsey took a second seat into her mouth. Rebecca's pussy started leaking juices and darkening her leggings as Lindsey somehow fit a third nipple in. Finally, Rebecca's legs visible quivered as Lindsey stuffed a fourth nipple into her mouth, greedily gulping down Rebecca's sweet, creamy milk.

Rebecca's hands latched into her last free breasts, the top pair, and began playing with her nipples: squeezing, pinching, pulling, and milking them. She let out a few low moans while doing this as she fought to contain how she was feeling so she didn't alert anyone else in the store. She bit her lip, she could feel herself climbing to orgasm. If she didn't cum here, she'd definitely have to when she got home.

Suddenly, she felt a pair of hands on her groin. Lindsey's hands began rubbing her pussy, quickly finding her clit. Rebecca had to brace herself against the wall, putting her arms over Lindsey and leaning into her. Her upper tits steadily streamed milk out as Lindsey was able to drink more faster from the lower four from the increased pressure.

"L-Lindsey, I'm going to cum soon i-if you keep that up." Rebecca moaned. Lindsey maybe tried to not her head? The Rebecca's boobs moved right after the said that felt like Lindsey tried nodding her head with four tits in her mouth. Either way, Lindsey kept doing what she was doing, and just as suddenly as this all had started, Rebecca came.

A deluge of juices ran down her legs, and milk sprayed from her top pair of boobs, which Lindsey reached up to milk. This milked Rebecca's orgasm for much longer than it would normally go on for, and ended up emptying all six of her boobs. Shakily, she sat down on the bench with a soft squelch beside Lindsey, both were panting. Rebecca looked over at her, and her eyes went wide. Lindsey's stomach was bulging out from her shirt, and it looked like she had opened her pants to give it more room. Rebecca's mind reeled that Lindsey had drank so much milk.

"All that was from me?" Rebecca breathed, running a hand over Lindsey's belly, which wobbled at her touch

"Yea, your milk is really good." Lindsey replied, "I couldn't get enough."

"I seem to make a lot, so I might need your help again to milk me." Rebecca giggled. Her eyes were taking Lindsey in, at least what she could see from right next to her, and she narrowed her gaze. She swore Lindsey was relatively flat, and skinny, but as she looked at her now, she looked softer, her legs thicker, her uniform tighter, and her breasts now round orbs straining against her uniform top. Rebecca didn't know what to think, really. She concluded her milk must've done it, but to act so fast? Already? And there was so much more in her belly, her big would she get?

"Well, uh, I need to get home, and get cleaned up. That fingering you did left quite a mess." Rebecca said, slowly getting up, legs slightly shaking. Lindsey just sleepily nodded, and giggled. Rebecca threw her shirt back on, grabbed her things, and made quickly for her car. Once there, she slowly settled inside, as she was still riding out the last aftershocks, and checked the time. She still had five hours until stream, plenty of time to get ready. She drove home quickly and showered. She found that having to get in and around each boob was a little more work than she liked, but that's just how it was going to be. While trying her hair, she considered what to do next, if anything, with the four hours she had until stream.
