I crawled on top of her boobs, grabbed Nicky by the head, and pulled her into a fierce kiss. By the time we finished kissing both of us were breathless. That opened the floodgates and Nicky confessed she had feelings for me. I told her I had feelings for her. We both cried, then laughed, then things got real hot and heavy.

We kept making out for a bit until I moved back to Nicky's breast and started to suck on her nipples. Even though I had milked her earlier that day they were already full to the brim again. I sucked and gulped from her nipples till my belly was sticking out like I was pregnant.

When I said I couldn't take anymore Nicky knocked me on my back and then pinned me under her massive tits. She said she wasn't letting me up till I drank every last drop from her fat udders. Being weighed down by her massive juggs forced to drink her milk drove me wild.

Even though I was sure I was full I started to suck again. Every swallow made me hornier and hornier. She kept demanding I keep sucking harder or she was going to take more of the pills right there. I wrapped my arms around her giant tits and sucked for all I was worth.

Finally, once they were fully drained Nicky pulled away from me. I was shocked to see my belly. It was so huge, nearly the size of an armchair. Nicky started to rub my belly all over, calling me a good little milk slut. My belly was stretched so much it had become incredibly sensitive. I couldn't help but cum over and over from Nicky's caressing. It was incredible I never knew I could drink so much or cum so hard.

We repositioned so that Nicky could eat me out at the edge of the bed. Resting her boobs on the floor, my legs wrapped around her head, she licked my pussy all over. Every now and again she would slap my belly making me squeal in pleasure and cum all over her face. God, it was so hot I'm getting tingly just thinking about it.

I lost count of how many times I came last night, it was just incredible. I fell asleep nestled between Nicky's enormous boobs. I don't think I've ever had a more comfortable sleep. I can't wait till Nicky wakes up I swear I'm going to shower in her milk or maybe I'll take a bath. Mmm that's so hot knowing Nicky makes enough milk now I can bathe in it. She's like her own personal milk factory. I think I'm going to have to go wake her up myself.

Dear Diary,

So it turns out all that milk I drank went to all the right places. When I got up this morning to get a drink of Nicky's milk from the fridge, I nearly fainted when I saw myself in the mirror, my belly had shrunk down, but everything else had billowed out. I can't believe this is happening to me. I never thought in my life I would ever be able to live out one of my fantasies!

My ass is so fat that the only thing I can wear right now is my leggings. Even they're pretty tight too. My boobs are the size of volleyballs, my nipples are fatter, thicker, and way more sensitive. My hips are wider; I've got like this layer of chub all over now that just makes me look so hot. Even my pussy is fatter and more sensitive.

I've taken to bringing a lot of Nicky's bottled milk into my room with me. I love it, it just tastes so good. Plus, I mean if it keeps expanding my body even bigger who am I to complain. Speaking of which I'm going to drink everything I have here with me now. I want my belly swollen with milk again. It makes masturbating so much more fun.

I'm up to four dildos in my pussy and four in my asshole now. I need to be stretched more to get off. Maybe I'll use the empty bottles this time hehe that could be fun.

Dear Diary,

Oh my god! Last night Nicky and I did the hottest thing ever! Nicky was walking around the apartment naked since nothing fits her anymore. I jokingly said that her nipples were bigger than cocks. Because they were! Anyway, Nicky looked me dead in the eye and said "well then why not use them like a cock?"

I've never gone from zero to gushing wet so fast in all my life. We went at each other like two horny rabbits then. I pushed Nicky onto her back so she was buried under her waterbed titties. Then I got on top of Nicky's tit and showed her hard nipple to its new home.

When Nicky's warm pulsing nipple entered my pussy I nearly came. It was just so naughty, so perverse, I loved it. I started to thrust onto Nicky's nipple and with every thrust, I could feel her warm milk spraying into me. I watched as my belly swelled out bigger and bigger and bigger.

That only drove me on, I needed more. It took some doing, but I managed to get Nicky's other nipple into my ass. With both of her milk factories stuffed into my holes, I went to town. Nicky's nipples are bigger than anything I've ever ridden before.

As I rode Nicky's tits hard her nipples only swelled out bigger, getting harder inside me. They stretched me so much I was stuck on Nicky's nipples. I had no choice, but to keep thrusting and humping against her ocean of tits. Not that I minded, it was a dream. Every pump from her nipples made my belly bigger. The bigger my belly got I knew it meant the bigger I was going to get.

So I just kept riding harder and harder. Both of us were screaming in pleasure as we came over and over from our bizarre sexual romp. Nicky just kept yelling for me to milk her tits harder, fuck her blimp titties, all kinds of sexy lewd things that just riled me up more and more.

I don't know how long we fucked for all I know is I kept going till my belly was bigger than me and I passed out. When I woke up this morning I had slid off of Nicky's nipples. She must have passed out too. So when her nipples grew soft I came loose.

Milk is now constantly flowing from Nicky's breasts. There is no way to stop it, she just keeps making more and more of it. Once I checked to make sure Nicky was okay. Which she was, she was asleep on the floor. I took me and my bloated belly back to my room for some well-earned rest.

Nicky's tits are filling most of the living room now. If she keeps getting bigger like this she's soon not going to fit in the apartment. We're going to have to figure something out soon.

Marua

Marua laid down her pen, closing her diary she put it back into her dresser drawer. She looked down at her belly and smiled. It was still full, nothing compared to how big it had gotten last night, but still, she looked well past the terms of pregnancy. Resting on top of her belly were her plump breasts. Once again the milk had done its magic making her breasts, ass, hips, thighs, nipples, and pussy all fuller.

Marua caressed her plump supple body as her hands roamed and she let out a moan of pleasure. She had always loved being touched before, now it was like an aphrodisiac. Even the slightest brush of one of her more sensitive parts had her loins frothing. One of her hands drifted down between her legs to rub her already drenched pussy.

"Marua!" Nicky called from the living room. Marua closed her eyes, chewing her lip, she kept rubbing her pussy. Nicky could wait a minute long enough for Marua to get out one quick orgasm. "Marua! Marua, get out here! Something is happening!" Nicky called louder.

Marua sighed and hopped off the bed "coming," she called back as she made her way down the hallway. The first thing that came into view was Nicky's gargantuan breasts still taking up most of the space in the living room. Did they always take up this much space? Marua thought to herself.

"Marua they keep getting bigger! They're just growing more and more!" Nicky said as she rubbed her breasts. A loud moan escaped her lips as milk geysered from her nipples, soaking the room.

Looking at her sister puzzled Marua said "Nicky I know they're getting bigger." She looked back at Nicky's gigantic udders only to realize what Nicky had meant. They were getting bigger right now. Marua watched as Nicky's bosoms pushed out fatter and fatter in front of her. Inching its way closer to her. Filling every last inch of the room with creamy white breast flesh.

Moving closer to her sister, Marua clutched Nicky's shoulder: "Nicky, what did you do?" she said as she looked at her sister in the eye.

Nicky chewed her lip as her breasts made another large swell out. They were pinned against the floor and ceiling now. Cracks were starting to form around them as they continued to get bigger and heavier with milk. "There were only ten pills left," Nicky started before letting out another loud moan of pleasure as her breast pushed out again.

The cracks spread as more and more pressure was applied to the floor, ceiling, and now the walls of the living room. "So I thought what the hell. I'm already taking four a day," she lifted the empty pill bottle to emphasize her point. "Let's just take the rest now, get it done and over with," she tossed the empty bottle aside "one last hurray you know?"

Nicky shuddered and gasped as her breasts lurched out fatter and fatter. The sounds of walls crumbling came from all around them as Nicky's breasts continued their rampant growth. Bursting through the walls and ceiling, her tits continued to fill the apartment and push out into others.

Nicky started to rub her breasts feverishly, moaning louder and louder "ahhhhhh Maura they keep growing faster! It feels so good! I want more!"

Marua looked down at her sister's flushed face awash in pleasure and couldn't help but grow even more aroused herself. Nicky's breasts growing out of control with no way to stop them and it was Nicky's own fault. Marua couldn't have wished for a sexier narrative. The only thing that would have made it better was if it was happening to her.

Over the past few months, the one thing Nicky never disclosed was where she got the pills from. Despite Marua's best efforts. There was nothing else Marua could do now but enjoy the show. Getting down on the floor next to her sister she stuck a hand down her shorts and started to rub her pussy.

She moaned loudly as she soaked her shorts with pussy juice. Marua used her free hand to bring Nicky's head over into a kiss. Nicky groaned into her sister's mouth as the two kissed passionately. The building rumbled around them as Nicky's udders continued to swell and swell and swell.

Crashing through floor after floor of the apartment building, everything started to crash down around them. "Ohhh fuck keep growing Nicky!" Marua cried out encouraging her sister. "Bigger, fatter, milkier tits! Don't let those blimps stop!" She shouted as milk pooled around them from all of the milk that had poured out of Nicky's tits.

Nicky looked like she was drunk. She was going through so much pleasure "ahhhhh! Yes! Fatter! Fatter! Fatter! I don't want my fat tits to ever stop! Ohhh there's so much pressure!" Nicky's behemoth bosoms continued to swell and billow out bigger and bigger like rising dough. It was only a few moments before her breasts had outgrown their apartment building and were pushing out into the streets.

Nicky screeched in delight as her tits slammed into other surrounding buildings. The friction from the brick and mortar was enough to make her cum over and over nonstop. "Yes! More! More! I don't ever want to stop cumming!" Nicky pleaded as her tits rolled over the tops of the buildings around them.

One by one, the building caved under Nicky's massive tits. Like a tidal wave of pale white flesh, her unstoppable mammaries spread across the city. Covering block after block in milk then tits. Marua watched Nicky lose herself to the increasing pleasure. She envied her sister so much right now. She wanted the same for herself.

"Bigger Nicky," Marua said to her sister, "you have to keep getting bigger and bigger and bigger." She stroked her sister's face lovingly "I love you so much, you're everything I always wanted to be. Keep going. For me." Marua kissed her sister again.

Nicky pulled away from the kiss: "Marua, I'm still getting bigger, but my boobs they're getting so tight," Nicky said as she rubbed her breasts.

Marua did the same. The once supple, yielding flesh was no longer soft, it was firm, tight even "you're making more milk than your nipples can spray out," Marua said as she looked up at the wall of flesh in front of her "what if you pop?"

"Unnnghhhh I don't know," Nicky said as she groaned loudly in pleasure "ahhhh the tighter they get the better it feels! Ohhhh fuck! I can't stop cumming!" Nicky quivered, bucked, and thrashed as her orgasms grew more powerful "but ahhhh I'm going to pop if this keeps going!"

Nicky shouted and moaned louder "unnnghh so tight! It feels too good! Ahhhh I don't care if I pop! I just want to cum my brains out! More! More! More! Tighter! Tighter!" Nicky's breasts started to vibrate as they were stuffed to their limits.

Her now city-dwarfing breasts were shaking all over Nicky screamed in pleasure as it felt like she was going through an everlasting orgasm. Finally, with a massive boom, everything went black for Maura.

Maura bolted upright as she woke "Nicky!" She screeched, clamoring to her feet, looking desperately for her sister. "No! No, no, no, no! This can't be!" Marua said as she looked around frantically for any sign of Nicky.

Then she heard it, laughter, and it sounded like Nicky. Marua ran towards the laughter "oh please be her, please be her, please be her," Marua begged tears streaming from her eyes. Relief washed over her as her eyes laid on her sister.

Nicky's massive breasts were all gone now. In their place was a modest pair of B cups. Maura would have lamented the loss of her sister's massive breasts. If it wasn't for the fact she was ecstatic to see her sister was still alive. "Nicky!" Marua sobbed as she ran to her sister sitting on the ground. Maura dropped to her knees and hugged her sister tightly crying "you're okay!"

Nicky returned the hug, holding her sobbing sister tenderly. She brought Marua's chin up and kissed her "yeah, I'm okay." Nicky smiled at her sister "that was amazing!" she exclaimed, "I, no, we have got to do that again!" Nicky looked around at the wreckage around her "ahhh well maybe we need to get a new place to live first."

Nicky blushed "and ahhh oh shit I'm going to need to get a job now aren't I?" She looked Marua in the eye "those pills cost money, and besides it is well past time I started chipping in," she squeezed Marua's shoulder "if we're going to be living together from now on."

Marua was dumbfounded she was not expecting this from her sister at all. Marua was trying to find something to say when Nicky kissed her again "I'm sorry I've been such a sponge; can you forgive me?"

Marua looked at her sister, she looked sincere in what she was saying. Marua giggled "I'll forgive you if you let me get bigger than you next time," she grinned devilishly.

Nicky grinned back "there's no way you're getting bigger than me," she met her sister's eye. After a moment the two of them started to laugh and hugged each other. All while sitting in the milk-covered mess that was now the city. Both couldn't wait till next time.

The End.
