Here's a bigger smuttier version of this story. Hope you like the updates.  

Fiona had been spending the summer at her grandparent's beach house. Even though her grandparents weren’t there most of the time. They spent their time traveling in their giant campers across other states. Which suited Fiona simply fine, she was twenty-one, and having a beach house mostly to herself meant this was going to be a hell of a summer for her. She was gonna have friends over all the time. They would have fires, surf, BBQ, hot tub, party, the works. Though given today was a rainy weekday Fiona decided she would just have some fun poking around in her grandparents' attic. 

As she had picked through old boxes, she came across some clothes stuff from back in the 50’s it was wild. Being something of a fashion designer in her spare time, Fiona was geeking out a little at the stuff she found. She wanted to take the clothes downstairs to try them on to see how she could alter them for a more modern appeal. As she pulled out various garments, she eventually pulled out a large apron. “Oh sweet,” she said, pulling it up looking at it. The picture on the apron was of an exceptionally pregnant woman. Fiona was surprised that an image like this would be printed back then. The woman on the apron had giant breasts; it wasn’t very modest for something made in the ’50s. 

Oh well it didn’t matter, what mattered was Fiona needed an apron and this would do the job. Having people in meant baking and cooking and as far as Fiona could see there were no other aprons downstairs. The picture was a little odd but whatever, the less money spent the better. Picking up the apron Fiona put it on. As soon as she finished tying the knot in the string behind her a strange warmth washed over her body. Her modest B cups started to swell out bigger and bigger before her very eyes. 

“Oh my god! What’s happening!” Fiona moaned as her breasts continued to expand out bigger and bigger. Her once small perky boobs were now the size of plump juicy watermelons. She could see thick nipples poking out through both her shirt and her apron milk pouring from her long, thick new nipples. Fiona’s cheeks flush as this experience turns her on. She has no idea what’s happening, but it feels quite good. Moaning dropping to her knees, her now beach ball size breasts bounce up and down. 

Next joining into the mix is her belly, her once flat tummy swelling turning into a large dome. Catching a glimpse of herself in an old dusty mirror “oh my god I’m swelling up like I’m pregnant ohhhh I keep growing bigger,” she groaned rubbing her belly. It pushed well past the normal size of pregnancy and kept lurching bigger. Fiona’s belly expanded even bigger than her currently giant breasts. Her now beanbag chair-sized belly continued to swell rounder and rounder. Unable to take her eyes off the mirror, Fiona watched as her thigh’s swell plumper, her hips flared out and her ass grew plumper and juicier. 

“Ohhh my body! It’s getting fatter! It’s not stopping! Ahhhhh!” Fiona chewed her lip as her breasts started to leak milk. Lines formed in Fiona’s face, crows’ feet develop on her eyes, her cheeks grow plumper, her features softer. It was like looking into the future, Fiona watched as she turned into an older, impossibly pregnant version of herself. Her breasts and belly continued to swell and swell and swell until finally, the knot she had tied in the apron let go. Once the string was undone the effects of the apron stopped. 

Huffing and panting, Fiona shakily stood up, and her belly was massive, now almost the size of a small bed. Her breasts are as large as she was, they continued to leak milk like a fountain. Fiona was in shock as she looked over at her massive body. She could only think of one thing, “my goodness, I’m beautiful,” Fiona said, taking in her giant breasts and belly “I can’t believe my breasts are so massive and my belly it’s amazing! I never knew a person could get so big,” she said looking over her body, Fiona started to rub her breasts and belly, letting out a groan “Ohh they feel so good too,” she said as she continued to play with her swollen bits. 

Rubbing herself all over more and more, she brought herself closer to orgasm. Up in the attic of her grandparents, Fiona grew more and more aroused as she played with herself. Giving in to the sensation her expanded assets gifted her, it wasn’t long before Fiona came hard just from playing with her breasts and belly. As she came down, she groaned lustfully “ohhh wow I’ve never cum so hard before. I want more!” Looking around the attic some more Fiona dug up a reel of string tying off one end of the coil to the left apron string she unraveled the spool until the other end of the string was in her hand. There was so much string sitting on the floor, now hundreds of feet of string. Could she really get that big?  

Well, there was only one way to find out. Reaching back Fiona tied off the other apron string, the sensation of growth filled her again. Fiona let out another moan of pleasure as she started to grow much faster than before. It was as though the apron could sense how much space it had to fill now. She continued to grow and grow and grow and grow. Her belly, which had once been the size of a small bed, was now the size of a small car. She came over and over as her breasts ballooned before her eyes. “Ahhhh yes! Yes! Bigger! I want to be so much bigger!” The horny woman bellowed as she filled the attic with tits and belly. Slipping a hand down between her legs, Fiona was delighted to find herself rubbing a much plumper, more sensitive pussy than she ever had before.  

As she rubbed her fat mons she shuddered in pleasure “ohhh fuck! Everything on me is growing!” She moaned as her hips stretched out even wider, her ass cheeks expanded with more and more fat to give her a massive MILF booty “unnnnggghh fuck! Yes! More! More! Turn me into the biggest, sexiest MILF of all time!” Fiona cried out as she pleasured herself on the floor of her grandparents' attic. The more she played with herself the faster she seemed to balloon. Her breasts and belly were pushing against the roof of the house now. “Ahhhhh so big! So much pressure! Fuck yes! Milk my big fat mommy titties! Fuck more! More! My udders feel so good lactating! Mommy wants to be bigger!”  

Fiona gasped as the pressure from the roof vanished as her expanding blimps burst through the roof, launching it across the street. Giant flesh-colored globes rose out from the attic like balls of bread dough swelling and rising in the heat. “Ohhhh fuck! I never knew being a horny mommy could feel so good! Bigger! Mommy wants bigger!” She shouted, loving the fact that the more pregnant she became, the hornier and better she felt. The pile of string on the ground was pulled apart more and more as Fiona’s belly pushed out bigger than the house, she was in. Her nipples were almost the size of cars now as her breasts expanded fatter and fatter with milk until they were as big as her belly.  

She was getting so pregnant her body had turned the milk production up to eleven and her breasts were swelling bigger and bigger out of control. Milk was flooding the streets as her breasts filled and grew tighter with milk. “Ohh my udders are so tight! They feel so good! God Mommy needs to be milked like the slutty cow she is! Fuck Mommy’s big milky titties are turning her on so much!” Fiona ranted, egging on her arousal, and driving her even crazier with lust. She humped and thrust against her belly as it pushed higher and higher into the air. It continued to swell and grow until it was bigger than a 747 airplane. Even then it kept growing, pulling the long string tighter and tighter. It kept growing and growing and growing and growing her belly was so massive it could fill a football field and still it kept swelling bigger.  

“Ohhhh god it’s getting so massive! Ohhh maybe I shouldn’t have used that string, but it feels so good! Bigger! Please Bigger! Ohhhh god I just can’t stop cumming! Mommy is such a horny slut! I just want to keep cumming my brains out while I grow more and more pregnant!” Fiona kept crying for more until finally with a pop the string untied from the apron. Fiona lay there panting blissfully as her belly and breasts jutted up into the sky like three pink blimps. She decided she was going to have to cancel some plans. Fiona was going to have a quite different summer than she thought she was, and she was perfectly okay with that.  

The only thing that could have made this summer better was if she could have gotten even bigger. It was only then Fiona noticed a box out of the corner of her eye. It was her grandmother's knitting supplies. There were at least a dozen balls of yarn in there. She pulled the box over and started to tie the balls of yarn together “mama’s about to get a lot more pregnant,” she said smiling up at her massive belly. 

The End.
