Vanessa got up the next morning, and found herself staring at the ceiling for a few uninterrupted minutes.
Maddie knocked on her door, her muffled voice emerging from the other side. “V? You alright? Can I come in?”
Vanessa answered with an affirming grunt, and Maddie stepped inside. “Did you um– did you want to…talk?”
Vanessa sat up, weary from tossing and turning all night. “They um…they got bigger.” Her extra set of breasts had swollen even more, looking to have reached a B cup. “Any word from the app?”
“None yet, no… It’s weird, I haven’t heard anything since we got started. How are you feeling?”
“I got excited at the idea of changing like you but I’ve stayed up all night thinking about these– these things and… maybe I like them?”
“Oh. Wait– So you’re… you’re not worried?”
“Weirdly enough…I’m not. Let me get dressed and I’ll meet you in a sec.”
Vanessa got dressed for the day, she couldn’t help but wonder if she’d get as big as Maddie too. She looked in her full length mirror at her topless self. She tried to picture herself with giant, milky, beachball-sized breasts. Her logical side tried to remind her how inconvenient it was for Maddie, but she couldn’t deny how wet she was getting.

Maddie was patiently waiting for Vanessa in the other room. They hadn’t thought about buying a breast pump yet, the fun of the milking clouded their foresight. She definitely needed to be milked this morning, her swollen breasts were feeling– not sore, but whatever sensation it was it was pulsing through her. Not to mention her nipples could be seen through her shirt from across the room. “Hey Vanessa, could you–”
“Do you think I’m gonna start lactating as much as you?” she asked Maddie when she came out of her room. She walked into the kitchen and opened a cabinet, pulling a box of cereal out…along with a packet of toaster pastries, and a couple of granola bars.
“I uh– I dunno. I mean if you did, we would definitely need to reconsider getting some pumps. Could you–” Maddie felt a tug in her bra strap, her breasts were begging to be released.
“Yeah, true.” Vanessa said as she grabbed an apple off the counter on her way to the table. She poured the cereal into her bowl. “By the way, did you ever look into what we’re gonna do with your milk, much less mine?”
Maddie unclasped her bra and began to take off her shirt. “Um yeah, about that. Could you–”
“I mean I guess we have a couple of options,” Vanessa said, spooning more cereal into her mouth, swallowing, and taking a large bite out of the apple.
“Vanessa.” Maddie sat topless on the couch, waiting for Vanessa to look up. She began to lightly press against her own breasts, now they were definitely feeling sore.
“Yeah?” Vanessa continued to just mindlessly…graze.
“Cooould– Ahem.” Maddie cleared her throat, holding her hand up to her neck and looking puzzled. “Could you looOOOook at me, please?”
Vanessa’s head whipped towards Maddie at the sound. The two of them sat in silence and stared at each other. Vanessa, with her mouth full of apple pulp, broke the silence. “Did you… did you just.”
“No.” Maddie averted her eyes.
“Maddie.” Vanessa swallowed the apple pieces, wiping the juice from her chin. “What’s going on?”
Maddie looked up at her. “I don’t knoooow. My breasts feel different today and– could you just help mmmMMmme out, please?”
Vanessa practically scrambled up from the table and ran over to Maddie, bucket in hand. “Oh– yes, sorry. I didn’t mean to–”
“It’s fine.” Maddie interrupted her, leaning over the bucket and brushing her hair away.

Later, Vanessa was attempting to tie her shoes. “Are you going to be okay while I’m in classes today?”
Maddie did seem in a much better mood. “I think I will, yeah. I don’t feel so weird anymore. But I think I’m going to stay home all the same.”
“Unf–  that’s good.”
“What is it?”
“Just how do you deal with the sensitivity?” Vanessa complained, still hunched over tying her shoes. “I’m not going to get far if every time anything barely brushes up against my nipples they instantly harden and make me horny.”
“Now you know how I’ve been feeling!” Maddie said, feeling the delicious schadenfreude. “Trust me, you get used to it.”
“Yeah well I doubt that, I’ve got double the nipples to worry about.” Vanessa grumbled.
Maddie looked very curiously at her. “Are you going to be okay while you’re in classes today? You said it yourself, you have even more to deal with.”
“Yeah, look!” Vanessa stood up and twirled. She had finally tied her shoes and matched it with black and pink leggings and an extra extra large black hoodie that practically swallowed her. “You can hardly tell I have bigger tits, much less a whole other set!”
Maddie beamed at Vanessa and her careless optimism. “Yeah, I guess you’re right. I’ll see you later, yeah?”
“Yeah!” Vanessa rushed over to Maddie and gave her a gentle kiss. “Don’t change too much while I’m gone!” And with that, she headed out.

Sitting in her English class later that afternoon, Vanessa kept thinking about this morning with Maddie. Wondering what’s going in with Maddie now and what that could mean for her. She got lost in thought about how much bigger her four breasts would get, or how much bigger she would get all over. She was definitely feeling lustier… thoughts of pounding Maddie’s pussy with the strap-on she had in her nightstand, or Maddie pounding my pussy. Vanessa shivered, wrapping her arms around herself at the daydream of Maddie sporting a huge cock strapped to her hips. Vanessa was almost salivating as her mind wandered to images of Maddie fucking her each way from here to Tuesday, being suckled from…
Vanessa had admired Maddie’s bottom heavy figure before she got massive breasts, and now Vanessa was quickly catching up. Her ass filled the seat she was in, and she could feel her hips squeezed together by the arms of the interconnected chairs. She could practically feel herself swell all over as the seconds ticked away… Her weight began shifting around her body, shivers of sensation shooting from her backside. Her hands began to instinctively move to her ass, or whatever she could grab of her hips. They were getting so squeezable, as she pressed down on her plush flanks Vanessa could feel some resistance against her hands, she was definitely growing– right now!
“Vanessa?”
She looked up, startled. It was the professor, standing in front of the board and looking only at Vanessa because she was the only one left in the room besides him.
“Is everything alright? You seemed distracted.” He asked.
She faked a smile. “No problem! Everything’s fine!”
It was definitely a problem. Vanessa wiggled her way out of her chair to find that her butt was bigger and jigglier than it was just an hour ago, she had grown wider and fuller from the waist down.
“I’m having some concerns about your performance in class lately,” he said, stacking loose papers into slightly less loose stacks of paper. Vanessa wanted to protest but he wasn’t exactly wrong.
“I’m sorry, I--”
“Even though your work is fine and you’ve still been turning in your assignments, I can’t help but notice that your in-class participation has been nearly nonexistent lately.”.
Vanessa was so focused on how transparent her tights must be that she was squirming while standing. “I’m really sorry, I am. I’ll try harder,” she insisted.
“Just making sure you’ve still got your head in the right place.”
What I wouldn’t give to have my head between Maddie’s jugs right now. Vanessa realized she hadn’t answered and blurted out “I’ll try harder, you got it!”
The professor could tell he wasn’t keeping her attention and waved her away. “It’s alright, see you next class.”
Vanessa left power walking down the hall, her thighs rubbing together, sexual friction warming her all over. She couldn’t deny the satisfying weight of her new posterior. She wobbled unsteadily when turning around corners in the hallways. She could feel the weight of her plush, vast rump wobbling behind her. Her cheeks were flushed and she could feel the heat in her face rising. Vanessa couldn’t wait any longer, she saw the sign for the bathrooms and turned down the hallway.
As if it was a sign from the gods: Vanessa spotted a “family” restroom right across from the public women’s bathroom. Vanessa practically skipped the rest of the way to the door as she swung open the door and slammed it behind her. The room smelled so clean and fresh, another sign from the gods that every surface had been wiped down mere moments ago.
Vanessa threw her bag down, and caught a vision of herself in the mirror. The hoodie that swallowed her this morning had begun to fill out. There was still plenty of bagginess to it but you could definitely see that Vanessa was sporting a seriously large chest underneath. Vanessa threw off the hoodie and quickly shimmied out of her leggings, kicking the shoes away from her as well.
The version of Vanessa that stood there was impressive to her. She turned and admired every new ounce of flesh as she punched, squeezed, and groped herself. Her breasts had definitely grown heavy, the bottom set now nearly matched in size. She brought her hands to her hips and stuck a little pin-up pose. She was mesmerized at how soft she was all over, even her tummy. It wasn’t exactly sticking out, but she could squeeze it and when she jumped it jiggled along with the rest of her. She wondered aloud, “It’s like my body has shifted to grow into a more suitably… bovine size!” Vanessa processed what just came out of her mouth, but she wasn’t scared. She loved her new body, and couldn’t hide her smile as she thought about enjoying it more. Vanessa propped one of her feet on the sink and started to touch herself as she groped her ass, caressing her pillow-like cheeks before giving one of them a slap. Vanessa spanked herself harder and harder, watching the force of her pain and pleasure ripple up and over her hips and down her thighs. The crease at her hips was deep, and all she could imagine was being grabbed there and getting railed. A red hand-shaped mark began to form, and she could feel heat rush to her bottom. She switched feet, striking another pose over the sink. She ran her hands over her chest, grabbing her top left breast. Her other hand stayed busy slipping in circles around her clit. What she wouldn’t give to feel filled right now. She imagined Maddie entering her with a massive cock; Vanessa started to yelp as she clamped her hand over her mouth. Her busy fingers moved wildly until she felt the immense wave of pleasure wash over her. Vanessa –flushed pink and skin glistening from a light sweat– gathered her clothes as she caught her breath. As she got dressed, the tightness of her clothes really sank in. Even after bringing herself to orgasm, she still couldn’t stop looking at herself. She put the hoodie back on over her amazing chest, and as she turned to leave she gave her ass a slap on the way out.

The moment she got home, Maddie nearly pounced on Vanessa. She kissed her hungrily as she started tearing off her clothes. Vanessa seemed surprised but definitely didn’t protest as she helped Maddie out of her clothes too. Within seconds, both girls were naked.
“Whoa, Vanessa!” Maddie’s eyes grew wide as she took Vanessa by the hands and gestured to spin around slowly. “Your ass is nearly as big as mmmmine!” Maddie cleared her throat nervously as the bestial sounds came out of her again, but Maddie shook the worry away as she embraced Vanessa.
“Please...” Maddie whimpered as she hurriedly kissed Vanessa.
“Do you need to be milked or do you need to cum?” Vanessa asked, taking one of Maddie’s gigantic breasts in her hand and pulling at her nipple, causing a bead of milk to form.
“Mmmm... both?”
Vanessa chuckled at the desperation in Maddie’s voice. She pushed Maddie onto the couch. “Wait there. I have a surprise for you.” Vanessa disappeared into her room as Maddie whimpered in frustration. When she returned, Maddie saw that she was sporting a purple silicon dick, connected to a harness that was lashed around her fat hips.
“You got a strapon?” Maddie said, trying not to sound too eager, lest Vanessa decided to tease her even more. She hadn’t cum in nearly four hours now and she was getting very very desperate.
Vanessa smiled. “Mmhmm. This new little friend came in the mail and I’ve been waiting to fuck you all day.”
Maddie laid back, her breasts wobbling towards her face, practically eclipsing all but her eyes. Vanessa climbed on top of her, spread her legs and got between them. She brought her fingers down to Maddie’s pussy to find that, unsurprisingly, she was already wet.
“Ready?” She asked, positioning the dildo at her beckoning slit. Maddie nodded, and Vanessa plunged her cock inside, making Maddie scream in response.
“Oh fuck... so goOOOood...” Maddie managed to get out in between moans and panting breaths as Vanessa fucked her. Maddie’s eyes shot open in fear, she looked up to Vanessa with an apology ready to go when Vanessa pressed a finger against her lips.
“Shhhhh baby. I like it when you… moo.” Slowly working the purple cock in and out of her, Vanessa hunched over as she took one of Maddie’s breasts in her hand and brought it up to her mouth. She began sucking on Maddie’s nipple and her milk immediately started flowing into her mouth.
Maddie’s head rolled back along with her eyes as she moaned again. “MMmmm fuck, Vanessa!”
Vanessa brought a milky, wet hand to Maddie’s lips, startling her. Droplets of milk had covered her hand while trying to drink and fuck Maddie simultaneously. Maddie took the cue and began sucking the milk off of Vanessa’s fingers, starting by wrapping her pillowy lips around Vanessa’s thumb. She locked eyes with Vanessa, and saw a smile crawl across her face. Maddie unlatched from Vanessa’s thumb, panting. “What are you plotting?”
Vanessa took back her hand and gripped Maddie’s hips, thrusting deep inside her. “Moo for me.”
“MMmm what? Are– are you sure?”
“Positive, my love.” Vanessa continued to thrust into Maddie, gyrating her wiggling hips and building up speed.
“MMMmmm…ooo.”
“Come on, Maddie.”
“MMmmmMMMooooo.”
“That’s it!”
“MMMmmmMMOOOO!!”
With how loud Maddie was mooing, it didn’t surprise Vanessa when seconds later she was cumming. Underneath her, Maddie was panting, out of breath.
“You wanna stop?” Vanessa asked. Maddie nodded and Vanessa pulled out and took the harness off. She waited for Maddie to catch her breath.
“Well, you still have another tit to empty,” she said, playfully grabbing at the full one. “And you still haven’t cum.”
Vanessa took that as the cue to assume the ‘position’ that the two of them figured out fairly recently over the course of Maddie’s transformation. She got up and grabbed an empty bowl as Maddie climbed off the couch and knelt in front of it. Vanessa positioned the bowl under Maddie as she sat down in front of Maddie and spread her legs.
Maddie immediately buried her face in Vanessa’s pussy, quickly finding her clit with her tongue. Vanessa grabbed Maddie’s head with both hands and wove her fingers into Maddie’s hair. Maddie’s hands meanwhile grabbed her own breast and started milking herself into the bowl below, making herself moan onto Vanessa’s clit, which in turn made Vanessa moan too.
This continued, with Maddie milking herself and tonguing Vanessa’s pussy while Vanessa couldn’t help but enjoy herself and the view. Maddie had gotten far better at eating pussy with the amount of practice she’d been getting, and it didn’t take long before Vanessa was gripping Maddie’s head tightly and cumming.
Maddie sat up and wiped her mouth off with the back of her hand. “That was quick.” she said with a wink.
“Mmhmm,” moaned Vanessa, still recovering from the orgasm. “Well that tongue of yours is very talented.”
Maddie picked the bowl up and walked into the kitchen to pour it into a bottle. Once her legs felt steady, Vanessa started putting her clothes back on.
“Hey V, can we talk about something?” Maddie walked back into the living room and sat down on the couch, still naked.
“Sure, what’s up?”
“You, girl! When you left this morning you could fit into your leggings and hide your chest. Now… I don’t think those leggings would stand a chance! Did your breasts grow at all?”
“I don’t think mine have grown at all today, what do you think?” Vanessa gestured to her breasts, which were nowhere near the size of Maddie’s.
Maddie reached out a hand and grabbed one of them. “Hmm... I don’t know.” Maddie grabbed two handfuls of Vanessa’s hips and gave them a playful shake. “But you’re clearly catching up to me in other ways!”
Vanessa laughed it off and gave Maddie a peck on the forehead, and headed for the kitchen. “I’m getting a snack, you horny beast.”
Once there, she cupped her breasts, inspecting them as best she could through her hoodie. They definitely weren’t growing as fast as Maddie’s and there wasn’t any milk yet, but four? Four breasts and no milk? She tried her best to feel grateful about this, as Maddie had struggled quite a bit during those first few days of growth. Maybe next I’ll sprout a tail and some horns before the milk comes in! Vanessa felt a stirring just as this thought crossed her mind, and it once again didn’t scare her. “Hmph!” She shrugged it off and put some popcorn in the microwave. As it popped, she crunched into another apple. She yelped as she felt a smack on her butt, and Maddie passed her in the kitchen.
“Well excuse me, ma’am.” Maddie winked at Vanessa as she opened the fridge. As soon as she saw the bottles of milk, which occupied the entire bottom shelf of the fridge, she spun around to Maddie. “I found something to do with my milk!” She said excitedly. Maddie looked intrigued. “There’s this service that we can do for expecting parents that need breast milk! You just register with the hospital, it’s perfect.” Maddie pulled out her phone to find the website.
Vanessa beamed at her. “Wow, that does sound perfect. So we just ship the milk to them?”
“Well I called them and they’d want us to come in with a sample so that they know it's not just like… repackaged cow’s milk.” Both girls chuckled.
“Well that sounds more than convenient,” Maddie said, scrolling through the website on her phone. “I’m in.”
Vanessa excitedly took the phone from Maddie and opened up the calendar app. “Hospital Visit - Breast Milk” she entered for Saturday.
