(Chapter 1)

"Ummphh," Anna grunted as she attempted to get her jeans to fit around her butt. "UMMMMPHHH!"

She winced in pain and began panting. She had to get these on somehow, even if it was just for one more day. She had class in 45 minutes! There was no time to shop for new clothing in that time.

Unfortunately, there seemed to be no way to get these jeans to stay on, either.

She exhaled and then sucked her enormous belly in as much as she could manage, causing for her face to turn very red. As she struggled to hold her breath, she made one last desperate attempt to get the pants around her waist. But it was no use. The harder she tried, the more exhausted she got, and she could even hear the jeans starting to tear apart.

Finally, she surrendered, and miserably pulled the pants off. Her jeans had lost the battle, and her big, soft, squishy bottom had claimed victory.

She placed her hands in her face and sighed. She figured there was no point in telling herself she was going to start that diet for real this time, or to make another piecrust promise (Mmmmm! Pie!) that she would hit the gym next week. She knew she wasn't going to do either, that she was instead going to keep pigging out at dinner, and that she was going to get even fatter than she already was.

On some level, she wanted to blame Elsa for this. After all, her sister hadn't exactly...encouraged her to lose a few pounds. But she hadn't told her to order both a pizza and specialty chicken from Domino's last night, either. God, why did they have to have such delicious and reasonably affordable deals? And why did she never let herself have leftovers?

Her belly made a loud gurgling sound, as though it were begging for Anna to give it more nourishment, but she was to ashamed of herself at the moment to obey its wishes. How was she going to get to class? That pair of jeans was the lost pair of pants she had which (barely) still fit her. She would have to call in sick to her professor, or claim that she had a funeral she had to go to, or whatever excuse she felt would be most likely to work.

Well, in a way, technically she was sick. Sick of herself.

"What's wrong, Anna?"

Anna had been so busy wallowing in her self-pity that she hadn't even seen her sister enter her bedroom. Elsa had always been more of a morning person than she was, and she looked completely professional as usual, wearing a casual yet stylish outfit and holding a cup of coffee in her hand. She looked like she could conquer the world if she wanted to. Anna, on the other hand, looked like Jabba the Hutt.

"I'm getting over the loss of a dear friend," said Anna morbidly, pointing at her deceased pair of jeans, now crumbled up on the floor with no hope of ever being worn by their owner ever again. "Also, I have nothing to wear to school now, so I'm pretty screwed."

"Surely you have some sweats or something in your closet," suggested Elsa.

Anna shook her head.

"I gave those to good will. After I spilled steak sauce on them. Twice."

"You worry too much, dear sister."

"I worry too much?" Anna placed her hand over her chest with mock outrage. "What about that time we went to Taco Bell and you spent the entire car ride home freaking out that you might accidentally cause a blizzard with your farts?"

"Touche, Anna. But I'm sure you'll be able to find something to wear if you think hard enough. When is your class?"

"In less than an hour."

"Oh," said Elsa. Her optimistic mood on the matter appeared to be going away now. "Well, that does complicate things a bit, doesn't it?"

"I'm ruined!" Anna lamented, placing her hands in the air, and unintentionally filling the room with the scent of her unshaven pits. "I'm going to fail the course now because I'm a disgusting slob!"

"Well, you aren't disgusting," said Elsa, giving Anna a light pat on the shoulder. "As for being a slob, well, there's nothing really wrong with that, is there?"

"I thought you were something of a neat freak. Heck, I think I even once caught you arranging the fucking cereal boxes in the cupboard in alphabetical order."

"That's beside the point," said Elsa, now circling around Anna, who was unsure if she was trying to come up with a solution to her problem or was just enjoying the sight of her younger sister wearing nothing but a thin t-shirt and panties.

Anna had a hunch it was probably the latter.

"Look, I'll tell you what," said Elsa, snapping her fingers together. "If you stand up and hold very still, I can try to make you a pair of jeans with my magic. But I can't promise anything. I've never attempted to make clothing for anyone other than myself before. I should add a disclaimer that I may end up freezing your lovely rear end instead, for which I apologize in advance."

Anna rolled her eyes. Elsa's "experiments" with her powers didn't usually work unless she really knew what she was doing (her attempt to make a water slide for the two of them out of ice one summer had resulted in both of them hurting their backs). But she didn't really have a choice at this point, not unless she wanted to be expelled from the school for indecent exposure of her derriere.

"Fine" she conceded, getting herself up from the floor. "But be careful!"

Elsa examined Anna for a moment, like an artist looking at a blank canvas she was about to splatter with paint. Then with a quick wave of her hand, she shot a gust of enchantment at her...which quickly consumed her shirt and her panties.

"Elsa!" Anna screamed, horrified. "You were supposed to make clothes, not destroy them!"

"I'm sorry, I'm sorry!" Elsa blurted out, waving her hand around again, but with nothing happening this time. "I guess I was thinking of something else!"

The young naked woman glared at her.

"How could you be thinking of that at a time like this?"

Elsa blushed, and clumsily scratched the back of her head.

"Well, you've been so busy with school, and it's been a very long time since we last...um...fooled around. And you just looked so adorable, so I guess I...must've...wanted to see you in your birthday suit."

Anna turned an even deeper shade of red than her sister.

"Look, sis. I'm flattered. I really am. But I can't very easily call my professor and tell him I'm skipping class to engage in some good old fashioned wholesome incest."

"Who says you'd have to call him?"

"What do you mean?"

Elsa was now rubbing her hands together, as though hatching a brilliant scheme to rob a bank or fuck her sister.

"Well, you haven't missed any classes so far this semester, right?"

Anna nodded. She hadn't.

"So...you could go ahead and use one of your absences today, correct?"

Anna nodded again. She supposed that she could.

"That still leaves me with the problem of having no pants, sis."

"Don't worry about that. You...you indulge me, and I promise I'll go to the store when we're done and buy you five pairs of pants."

Anna groaned. Once again, her sister had succeeded at coming up with a decent bribe.

"Very well," she said, holding her hand out to shake Elsa's. "We'll...we'll do it your way. But how come you always have so much money anyway?"

"Oh, you could say I have frozen assets," Elsa replied slyly.

"Well, just know that I don't want any dollar store jeans," Anna said as she went over to the door to lock it shut. "I don't know how you always find a way to talk me into these things."

"Maybe because it doesn't take much effort to coax you." Elsa's voice was cheeky and full of joy. She was clearly excited over what the morning was about to bring them. And although she wasn't going to say so out loud (she was still too annoyed for that), Anna had to admit that she was pretty happy about it, too.

She prayed that no one would ever find out about it.

(Chapter 2)

"Make sure all the curtains are closed," Anna whispered, stumblingly backing away from the windows. "I don't want for anyone to see us!"

"But it's such a pretty day outside," Elsa objected, but she complied and pulled them all shut in an efficient yet leisurely manner.

"You might not be saying that if we end up in jail tonight. Last I checked, incest wasn't exactly legal here."

"It's not like we're doing anyone any harm." Elsa was removing her top and unstrapping her silver bra, causing for her two round, smooth breasts to come out and greet Anna. Even in her rather peeved and somewhat anxious state, she could feel her mouth start to water as she looked at them. They were so radiant with beauty that she wondered if it was possible for Elsa to masturbate to pictures of herself. She was a living portrait of elegance.

Anna, meanwhile, figured that if she were ever to look at pictures of herself, she would feel like she was glancing over a BBW fetish website.

"You're getting right down to business, aren't ya?"

"Let's just say I've been 'in the mood' for a long time, sis." Elsa was already out of her pants and was delicately relieving herself of her panties. Her full bush immediately began to entice Anna, inviting her to do some unspeakable things with it.

She could feel her toes begin to curl just looking at it. She was amazed by how little time it was taking for her to become horny. Elsa was certainly a sight for sore eyes...a sight for sore eyes who happened to come from the same mother that she did.

God, this was wrong. This was so, so, so, so, so wrong. And that was one of the things that turned her on about it.

Giving Elsa's nude body a quick look was enough for Anna to tell that she had actually gained a little weight herself since they had last had sex, though she was by no means becoming chubby. On the contrary, the pounds she had added gave her flesh a pleasing form of pudge, just enough for Anna to picture herself giving little pinches to it should she decided to do so. Anna, on the other hand, had so much flab on her that she wondered if she could make a small purse out of her skin if she was willing to sacrifice some of it.

"There's my yummy Anna," said Elsa happily, placing a finger over her mouth and giving it a tiny lick.

"Should I be worried when Thanksgiving comes around?" Anna asked with mock terror, placing a hand over her chest like she was going to faint. "I'm starting to think you might be fattening me up for reasons other than sex."

"No one needs to fatten you up, dear sister," Elsa purred, approaching Anna and placing her index finger inside her belly button. "You do plenty of that on your own."

Anna smiled, but felt slightly embarrassed at the same time. Her belly really had grown bigger in recent months. Sometimes she felt so full when she carried it in her arms that she wondered if she might be dangerously close to exploding. Yet it was never enough to get her to try to stay away from vending machines at school.

"Your body is a thing of magnificence, Elsa." Anna blushed and absentmindedly stroked the hair on the back of her neck. "When people look at you, they turn their heads to catch a glimpse of your ass as you walk by." She paused briefly to reach behind Elsa and give her left butt check a pinch. "When they look at me, they mutter words like 'heart attack any day now' and the like."

"I'll bet you many of them find you attractive, Anna," said Elsa, closing her eyes as Anna continued to give her bum little squeezes. "And if they don't, screw them! There's plenty of you to love, as far as I'm concerned."

"I'm not sure if my doctor would agree with you." Anna chuckled awkwardly. During her last visit to her physician, she had been warned about the weight she was gaining, and was told something about how it "wasn't normal" to get out of breath from walking from one end of a hallway to the other. She was so depressed from the trip that she went to Baskin/Robins afterwards to cheer herself up.

"There are plenty of fat doctors, Anna." Elsa was placing her arms around Anna's shoulders. She could feel a brief rush of her coolness flowing through her. She got chills whenever Elsa touched her this way...in more ways than one.

"Mmmhmmmm," went Anna. "If I'm not careful, I'll cum before we even get started."

Elsa leaned in to kiss Anna on the mouth. Anna responded on instinct and kissed her back, only now feeling bad that she had neglected to brush her teeth that morning. Elsa didn't seem to object to her breath, though, and continued to retaliate with her tongue, which Anna soon felt going into her throat. It slid around back and fourth, occasionally coming into contact with one of her yellowing teeth before releasing itself so Elsa's lips could make another sloppy interaction with Anna's. They both had their arms around each other now, pressing their bodies closer and closer together, and Anna's nipples crushed into Elsa's, causing them to tilt upwards.

"You've gotten even more cuddly," Elsa whispered. "I love my cuddly, hairy, massive sister. I love her so much."

Anna felt both flattered and humiliated by Elsa's comments about her weight. Yet she wanted her to go on with them.

"You know, the other day, I almost got my butt stuck in the door when trying to exit a restroom stall," Anna said in-between their smooches. "I think I may have to start using the handicapped toilets. They have wider entrances."

"Mmmhmmm, that would've been a hell of a thing to have to ask an ambulance for," Elsa breathed seductively. "'Hello, 9-11? Yeah, my big, fat, enormous bottom is stuck in a toilet stall. Please send help...and a plunger!'"

In spite of herself, Anna laughed at her sister's joke. But, then again, she was also enjoying what they were doing 'in spite of herself' as well.

"I suppose I should've known this is why you never did anything to stop me as I was getting plumper and plumper." She was licking Elsa's sweet, rosy cheeks in-between her sentences. "You were waiting for me to become ready for harvest."

"Oh, so now my pumpkin has finally figured out my filthy secret." Elsa was grinning at her, her eyes glinting with a dirty sort of passion. "I'm amazed you didn't ever catch me touching myself when I looked at you."

Anna raised an eyebrow.

"How long was that going on for?"

"Would you believe me if I said since we were teenagers?"

"Wait...no way. Really? I mean, you liked boy bands, Elsa. We both did."

"I would watch you from a crack in my door. I guess you never caught on because I usually did so when I was 'busy with homework' or something. You'd go to the fridge at night, your chubby bottom bouncing up and down as you did so. I'd slowly rub my snatch and pray to God you wouldn't hear me moaning."

Anna wasn't sure what shocked her more: the news that her sister had been masturbating to her for years, or hearing Elsa of all people use the word "snatch."

"I suppose I should be in awe at how good you are at keeping secrets," said Anna, uncertain as to what else she should say right now.

"Well, I was raised to do so," said Elsa. There was the slightest hint of sadness in her voice as she said that, though it was brief. "So...um...you wanna do it in my bed?"

"Your bed? Elsa, you do want to have a bed to sleep in tonight, right? I might crush it to bits!"

"Which would be extremely hot, so you know," answered Elsa slyly. "My own sister, so heavy that she destroyed my bed. It's a pretty amusing thought, I must say."

"You might not think that if you're stuck sleeping on the couch."

"It's worth it, trust me. Shall we go over there then?"

Anna cautiously nodded.

"Just so you know, I'm not paying for a new bed for you." Giggling, they both went to Elsa's room to continue the fun.

(Chapter 3)

"Jesus, Anna, are you exhausted already?"

Anna had her fist on her chest, huffing and puffing and struggling to catch her breath. She was close to wheezing and could feel herself growing red.

"The walk to your room was longer than I thought it would be."

"Do you wanna take a break before we continue?" Elsa's voice was concerned, but Anna wondered if seeing her giant sister close to passing out after walking twenty feet or so was also exciting her on some level.

"I'm...I'm good, I think." She looked around. Elsa's room was so much neater than hers was, although she supposed that shouldn't surprise her. At the very least, her sister had no empty pizza boxes on the floor.

"Your room is nice," she murmured. "I could probably learn a thing or two from you. I don't see any 2-liter bottles of Pepsi anywhere."

"You know, you are allowed to put those in the fridge, instead of under your desk." Elsa had laid herself down on top of her blankets, which smelled as though they had just been cleaned. "I enjoy a cold glass of soda every now and again myself, hard to believe as that may be."

"Well, when I'm binge-studying, I tend to down an entire bottle in one night. It's for...stress and shit."

"How does that account for all the soda that goes missing during summer break?"

"I...um...plead the fifth."

She looked at her sister, spread out across her bed like icing on a cake (Mmmmm! Cake!), her nipples like cherries, her pussy like an eclair filled with Boston cream.

"I could eat you up," she whispered. "After all, I haven't had my breakfast yet."

"I won't try to run away." Elsa's voice was becoming breathless again. "Come on over and help yourself."

Anna got on all fours, her belly drooping to the floor as she did so, and crawled over to Elsa's bed. Incestuous desire was starting to take over, so much so that she hardly felt humiliated when the mattress let out a terrible creek of agony as her gigantic body located itself next to her delighted sister. Without saying anything, Elsa climbed on top of her, and began kissing her heavily freckled breasts.

"So big," she cooed as saliva evacuated itself from her lips. "So plump, so juicy. Mommy Anna, do you mind if I have a little drink?"

"Mommy Anna?" She felt like she had mentally spat out a sip of water she was drinking after her sister said those words. "Elsa, um, I don't have any milk...even though I know I look pregnant."

But Elsa didn't answer, and placed her mouth on Anna's right nipple, giving it a massage with her tongue before slightly grinding on it with her front teeth. Anna could feel her toes begin to curl with unexpected force. Elsa went on to suck, harder and harder, her slurps becoming more and more audible, not to mention wetter. Anna tilted her head back, as Elsa moved on to her left nipple to repeat the same procedure.

"Fuck, Elsa, how long have you craved this for?"

Elsa took a break from her job to look up at Anna.

"Would you believe me if I said since we were teenagers?"

"Jesus, again?" Another mental spit of water. "Fuck, Elsa, I had no idea. How old exactly were you when you began...um..."

Elsa rested her head on Anna's titanic stomach, closing her eyes with satisfaction as it slowly rose and fell with each breath her sister took.

"Well, I think I was around...14? I guess that means you would've been around 11 or 12, which I know must sound horrible. I was watching you outside. You were fat back then as well, although not quite to the extent you are today. Anyway, you were bent over, wearing pants which didn't fit you, because mom and dad bought you small sizes in the hopes you'd lose weight."

"Wait, what?" A third spitting of water took place in her mind. "They always told me the stores were out of the bigger sizes!"

"Fuck, really? Sorry. I...um...I thought you knew." She placed her finger in Anna's belly button and gently twirled it around. "Anyway, you were bent over, and...um...well, I saw your butt crack. It was covered in adorable ginger freckles. I...um...took some binoculars out and looked through them so I could get a better look. My free hand went down into my skirt. It was an intense sensation I had never experienced before. I...I found myself rubbing myself harder and harder...until finally I felt something sticky on my fingers. At first, I thought I had peed myself, but..."

"I see..."

Anna wasn't sure what she could say beyond that right now. This was all a lot to take in, like a Golden Corral buffet just before closing time.

"Well, as time went on, and you grew up and became a young woman, I...I fell more and more in love with you. I didn't tell anyone, of course. Bad enough for my parents I had snow powers. Can you imagine what they would've said if I had admitted I wanted to marry you?"

Anna could feel herself sweating profusely now. This conversation was making her more than a little uncomfortable, but it seemed to be something Elsa needed to get off her (naked) chest.

"I guess you were disappointed when I lost some weight before gaining it all back again?"

Elsa shrugged.

"I was a little. But I knew mom and dad were practically forcing you to exercise at that point. Cutting down on your desserts. That sort of thing. But a lot of good it did, right?" She gave Anna's tummy a firm and playful poke.

"Yeah, they'd probably be rolling in their graves if they could see how I turned out...well, at least they would be if they were actually in their graves, instead of somewhere at the bottom of the ocean."

"On bad days, I kinda like to think they got eaten by sharks." She looked down at the palms of her hands sadly. "I mean, I'm sorry, I know that's a disgusting thing to say, especially about my own mother and father, but..."

Anna sat herself up just enough to give Elsa's hair a tender pat.

"It's okay, sis. I understand things weren't exactly...simple between you and them."

Elsa nodded.

"Do...do you want to keep going with this? I mean I worry I've kinda ruined the 'sexy' mood now with all of my talking."

Anna took Elsa's head and pulled it close to hers. Her sister's smile returned, seemingly reassured by the gesture, her lips colliding with Anna's and finding comfort there.

"I love you," Elsa's hushed voice repeated between each kiss. "I love you...I love you...I love you..."

"The feeling is mutual, honey," said Anna, rubbing her sister's bare shoulders. "But you're still going to owe my everything you promised when this is over."

"I know, I know," said Elsa slyly, her mood clearly improving now. "But first, let me get a good look at your ass. I have a new trick I've been meaning to try."

(Chapter 4)

Uncertain of what Elsa had in mind but quivering with anticipation to find out, Anna turned herself onto her immense gut, sticking her mammoth basement up towards her sister.

"There you are, beautiful." Anna could feel Elsa's hands kneading her backside like a kitten on a willing lap. "It's been too long since you and I have seen each other."

"Are you...talking to my ass, sister?"

She could hear Elsa chuckle.

"Maybe I am. After all, it is very good company." She rested her head on it like it was a pillow...if said pillow was the size of a beanbag cushion and smelled like a compost heap.

"Mmmmhmmmm. I could fall asleep here."

"Um...I wouldn't do that if I were you," said Anna, turning back as best as she could as she could manage from her position to glance at her sibling. "The forecast this morning calls for wind and thunder if you follow my meaning."

"I'm not worried," moaned Elsa, who was caressing her ass as though it were a beloved child. "I'm with my baby, and that's all that matters." She gave her butt cheeks a firm clasp with both her hands. Anna could feel her lightly sharp fingernails going over her various squishy rolls of fat, taking the time every now and again to give them a short but notable pinch. The sting of each of these ever-so-tiny scratches gave her an almost indescribably perfect combination of displeasure and arousal.

"Is your 'surprise' a spanking, Elsa?" Anna braced herself, crossing her fingers that the answer to her question would be yes. Her caboose would certainly give her sister plenty of "material" to work with.

"No, my bad girl. It's something far more...daring than a spanking. Are you ready for it?"

Anna could feel her heartbeat racing now, but managed a slow nod.

She could hear Elsa taking a deep breath behind her, followed by the sound of her rubbing her palms together and muttering something to herself which Anna could not make out. She then felt Elsa's delicate hands stretching her gross cheeks apart, exposing her hairy, pungent anus. She could sense her lips moving closer to it. Was she going to lick it like she had the last time they made love? No, that wouldn't be "something different" as Elsa had promised.

She closed her eyes, waiting...then she felt it. A slow, long gust of cool air blowing into her butthole. It was her sister's breath. She had apparently learned how to use her powers through her mouth. Anna wanted to come up with words to describe the sensation, words that justified the feeling of euphoria she was going through right now. She could feel the individual hairs inside her ass being blown, was able to savour the soothing breeze that went through her like a backwards fart.

"Oh, God, sister! OH, GOD!"

"Do you like it?"

Like it? Anna felt like she was being fucked by a goddess. Maybe she was.

"Please...keep...going..." Her words were pants. She was gonna cum soon. It was quickly becoming too overwhelming to contain her load.

She heard her sister's faint blow, felt it enter her, felt it cleanse her. Oh, fuck, this was it. She felt bad in a way for how fast it was taking her. She was gonna...

"TURN ME OVER, ELSA!"

With surprisingly little effort given how much bigger Anna was than her, Elsa flipped Anna onto her back. Anna was rubbing her pussy with animalistic force now...and then she squirted in a way she never knew was possible. The white pudding ejaculated from her like water out of a toy gun. It splashed into her sister's face, then the second spray came. It sprinkled itself on Elsa's breasts and tummy. She was smiling at Anna, like an artist who was satisfied after finally finishing a painting.

"Did I do good?"

Anna nodded...then felt a sensitivity between her legs of another sort, the kind she usually felt for whatever reason right after masturbating.

"Ummm...I have to pee, Elsa. Bad."

"Be my guest."

Anna slowly began to get up. The walk to the bathroom already seemed like a very long hike...but then Elsa placed a hand on your chest.

"I never gave you permission to leave my chambers."

"But Elsa, where will I...?"

Elsa laid herself down next to Anna, grinning at her with a twisted look of lust.

"Oh..." Anna was fidgeting with the urge to urinate now. "Are...are you sure?"

"Would I be looking at you this way if I weren't?"

Anna looked at her sister. She did enjoy seeing her happy. In fact, she loved it more than almost anything in the world (well, except maybe for chocolate cake).

"God, something must be wrong with me." She laid herself back down, consenting to Elsa's desires. "But you may have to buy me a shirt or two as well once we're done with this."

(Chapter 5)

"Sooo...how do you want to do this?" Anna shifted her thighs around, certain that her bladder would erupt any second. "And hurry, because I think my dam is about to burst!"

Elsa curled up snugly next to Anna, wrapping her arms around her shoulders.

"Just...do it."

"Fuck, you mean here? On your bed?"

Elsa purred.

"You don't see any toilets in this room, do you?"

Anna hesitated, but her waterfall of urine wasn't going to wait. After carefully pulling her legs apart, she did what she had to do. Pee gushed out of her and trickled down her legs, onto Elsa's blankets, and onto Elsa herself. She balked a bit as she watched her tinkle flow out of her. It smelled very strong and was an extremely unpleasant shade of yellow (Anna didn't always drink enough water). But Elsa didn't seem to mind. She was whispering small cries of sexual joy to herself, as though she were rooting for Anna's increasingly soggy puddle of piss to finish some sort of obscure marathon.

"That was...fuck." She was soaked with her own sweat and her sister's urine now. "That was...thank you, Anna."

"I'm sorry I didn't have still more to give you," said Anna, the last tiny drips of pee dripping from her pubic hair. "Maybe I should make an effort to drink plenty on days when we have sex."

Elsa breathlessly muttered something in agreement. She removed her arms from around her sibling's shoulders and climbed on top of Anna, raising her white bush above her sizable tummy.

"I have a confession to make, dear sister. I'm finding I have to go myself."

Anna's eyes widened.

"Shit, sis, I wasn't expecting for..."

Elsa placed a finger in front of Anna's lips.

"Shhhhhhh."

Elsa hadn't been exaggerating when she said she had to go. A steady stream of pee flowed from her, dribbling down Anna's stomach like "lava" from a volcano at a science fair. It felt so warm on Anna's flesh, and she was shocked by how much she liked the feeling as it oozed into her belly button and crept into her crotch. God, only Elsa could make peeing beautiful and graceful. She was amazing like that.

"I think I'm gonna cum again if you keep this going," Anna gasped, fully aware that she must stink even more than usual now but sensing that her sister loved that. "Who knew that being used as a human toilet could be so fucking hot?"

"Try searching 'golden showers' on the internet, Anna. You'll find I'm not the first person to try this."

She gleefully winked at Anna and bent over to kiss her on her moist lips. The sisters' consensual lust for each other became dominant over them, and Anna soon had herself on top of Elsa, her round, fat breasts dangling over her face. She could feel her nipples making contact with Elsa's vaguely wet nostrils, could relish Elsa's tongue as it gave her boobs a random dab. She pressed her bush against Elsa's and grinded into it, their vaginas connecting in sexual unity that demanded them both to have an orgasm. They both let out a cry as their juices spurted out, with Elsa's gooey gift entering Anna's open lips. Anna gritted her teeth together as she felt in enter her. She normally had to use a turkey baster to get that kind of impact in her personal cave.

"Who says only men and women can do missionary, huh?" Elsa chuckled at Anna's joke, and they both laid there for a moment before saying anything else, bathed in their pee, their cum, and their nakedness.

Finally, Elsa broke the silence.

"I know what you should do now."

"What? Besides send you to Sears so I can walk out of the apartment again, that is."

"You should step on the scale."

"What? Elsa, please, I haven't done that since the first time we fucked."

"Exactly, sis." She stroked on Anna's cheek. "What better way to celebrate this amazing morning than by finding how much you've gained since then?"

"Last time I weighed 289," Anna sighed. "Though, on the bright side, I did make 289 dollars as a result."

"Does that mean you want me to pay again?"

"Is that an offer?"

"It might be."

Anna took a deep breath.

"Very well. But then you go straight to the store. I sadly don't think I'd be able to show up for my night class naked."

(Chapter 6)

The girls made their way into the bathroom, both stinking of urine which lazily dripped off of their soaked bodies as they walked. Anna was quickly becoming fatigued by the brief journey, stopping twice to place a hand over her chest and collect herself. Even though she was a young woman, her immense weight caused for her heavy breasts to already start sagging a little, and they bobbed along obediently with each step she took.

"So...the whole pee thing...that was..."

Elsa cleared her throat a bit.

"I'm sorry, Anna. I know I threw that at you out of nowhere, but it's something I had been dying to do for ages. Were you...um...okay with it?"

"I'm shocked by how okay with it I was. But you never really struck me as the kinky sort. Like, at all."

"You came twice, so I must've done something right this morning."

Anna smiled at her, relieved that they had finally arrived at the bathroom. Oh, how she hated walking!

"I'm quickly learning a lot about what I enjoy from you. But when exactly did you find out you...well, liked pee?"

"I guess it was years ago." She sat herself down on the toilet, pulled a small razor out of a bag she kept near it, and began shaving her delicately beautiful legs (Anna looked down at her own legs, which were so hairy that they looked like they could use a lawnmower at this point). "I mean, I've never told you this, but when I was younger, I...kinda used to be a bedwetter."

"You're joking."

"No. And I stayed one for a long time. I think it may have been from being nervous, I don't know. But God, I was terrified of anyone ever finding out. I mean, I would wash my own clothing and everything, even when mom told me she could do it herself. However, in spite of my best efforts, eventually mom discovered my secret, and..."

She winced as she gave herself a small cut with her razor. A tiny stream of blood began flowing from her right kneecap.

"It's okay, Elsa, you don't have to keep telling the story if you don't want to..."

"I'm...I'm fine," she muttered as she took some toilet paper and began wiping the blood off her leg with it. "Let's just say that mom wasn't amused. She said that if I couldn't control my bladder, then there would be no chance of me ever being able to control my powers. And then she told father. After that, doctors were brought to my room. I was lectured about how this shouldn't be happening. Warned about what other girls my age would say if they found out. I was twelve at the time."

Anna hated herself for having no idea what to say. She just absentmindedly fondled the rolls of fat on her stomach, which was something she did a lot in these situations for some reason. It was a terrible and gross habit, but with a belly like hers, it was hard not to play with it every now and again.

"Anyway, I was forced to start wearing Depends. I had no say on the matter. At first, I was profoundly embarrassed about it, as I guess anyone would be. But as I became a teenager, I found having them...strangely liberating. I mean, there was something disgustingly freeing about being able to pee at the dinner table without anyone knowing I was doing it, you know? Eventually, around the time I began having 'feelings' for you, I got a similar amount of pleasure out of pissing myself."

She coughed into her hand, before blowing a soft cooling breeze on her open wound.

"Oh, God, Anna, I feel ashamed even telling you that..."

"No, Elsa, I'm the one who should be ashamed," said Anna, scratching her naked butt. "I mean, I had no idea you were going through something like that when we were growing up! There must've been so many times I came across as insensitive towards you without even knowing it."

She brushed her greasy pig tails to the back of her shoulders. She knew she had to try to lighten the mood in some way.

"Still, my dignified sister Elsa had a diaper fetish? That is pretty big news to me, I must say."

"Well, once I stopped needing the Depends, it became a lot more taxing to...indulge myself. Because mother insisted on washing all of my clothing herself after she found out about my accidents. You're going to hate me for saying this, but shortly after she and father died, I began peeing myself in my nightgown somewhat regularly. I knew they could no longer judge me for such things anymore."

She took a deep breath through her nostrils, then shifted her somewhat grim facial expression to a smile.

"So...Anna, you still have to get on the scale for me."

"Damn," said Anna, feeling butterflies starting to give birth within her stomach. "I guess a deal is a deal, even if it's one I was maybe too easily talked into making."

Feeling brave, terrified, and almost indescribably humiliated, Anna stood her filthy feet up onto the scale. She wondered if it would die of a broken heart under her weight.

"What does it say, Elsa? I can't see even if I lift my belly up."

But Elsa was grinning with what appeared to be sheer delight. Anna wasn't sure if that was a good sign.

"Well, Anna, you've done it. You now weigh 300 pounds. Well, 305 pounds to be precise."

She seemed to be a lot happier about the news than Anna was.

"Wow, um, maybe I really should go on that diet my doctor has been scolding me on..."

She could sense her cheeks turning pink, illogically wishing that the number was an even 300 pounds. Weighing five pounds more than that made her feel much more obese for some reason. It also made her long for a cinnamon bun (or three) in order to lift her spirits up.

"Now we know why your old pants had no chance of surviving," Elsa said soothingly into her ear as she stroked her neck. "But you'll feel better once you get your rewards, even if I have to buy your jeans in size XXXXXXL now."

Anna scratched one of her chins, contemplating what Elsa had just said.

"Do you think that will be big enough?"

Elsa burst out laughing.

"Maybe it would be easier for you to consider becoming a nudist? I wouldn't have any complaints about that."

"Oh, ha, ha, ha," went Anna, laying herself down on the floor. It was sticky and smelled strongly of cleaner, but all she wanted to do right now was take a morning nap...and she didn't feel like walking all the way to her bed to do so.

"Would you like me to get you a blanket?"

"No, thanks." The 305-pound woman yawned. "But when I wake up, you'd better have what you owe me."

"I'll head out as soon as I get dressed." Elsa was now staring at Anna intently, and looked as though she was debating whether or not she should say something.

"What is it?"

"Oh, Anna, this morning..." Elsa's voice was unsteady. Elsa's voice was almost never unsteady. What was going on?

"This morning was...well, amazing. I don't know how else to describe it. And…I love you, Anna. I love you so, so deeply. I...I know it's fucked up. I know I'm probably going to Hell for it. But Anna, I..."

Anna was starting to get concerned now.

"Elsa, is everything okay?"

"No, Anna, it isn't. Or, rather, it is. But...um...we'd have to work it out. I mean, it wouldn't be easy, and I'm not sure how we could pull it off. But Anna..."

She now got down to her knees, which still reeked of urine which was now drying up.

"Anna, will you...marry me?"

A/N I seriously recommend ElsaIsLove's fanfiction and DevitantArt Accounnt of the same name if you liked this chapter.
