chapter 3

Come Christmas Eve all was well between the two sisters. Trish - now going by Patty full time at her sister's insistence had moved in with Rhea and Donny the day after Rhea's birthday and had assimilated into her new role as "big sister" seamlessly. Patty paid board to her little sister and did most of the chores around the house except for the cooking of course. Rhea delighted in making sure her once slim sister continued to expand through her cooking, deliberately serving bigger portions for her and making sure there was always plenty of dessert.

"Ooh donuts for dessert?" Asked Donny

"Just the one, the rest are for Fatty Patty" replied Rhea "speak of the devil"

They were interrupted by the unmistakable creaking of the stairs as Patty made her way down them, the couple watched as her bloated figure descended, belly and second chin jiggling as she did.

"Hey sis, do you have any bigger trousers? These ones won't fasten"

"No Patty, those were the ones I tried wearing last year and you're much bigger than I was then. How much do you weigh now anyway?"

"189 lbs last time I checked" blushed Patty.

"Yeah much fatter" replied Rhea as she playfully slapped her sisters belly "don't worry, you can wear sweats to Mom and Dad's tomorrow and we'll go shopping for more fat girl clothes for you in the new year".

"Okay" sighed Patty "Ooh can I have a donut?"

"You can but don't spoil your appetite, I've got a big dinner coming your way."

The holidays weren't so kind to Patty's waistline. She managed to put on another 5lbs over Christmas week alone. This bought the necessity of the girl's shopping trip up in level with Patty needing clothes before she returned to work, the girls hit the New Year's sales.

As Rhea was driving the girls to the mall she couldn't help but glance at her larger sister, absent-mindedly munching on a package of cookies in the passenger seat. Her figure was largely hidden by the hoodie she seemed to live in now but you could still make out the outline of her plump belly and her spongy thighs were pressing against her sweats so much that you could see them jiggle after every bump.

"What are you looking at?" asked Patty through a mouthful of cookie, stirring Rhea from her thoughts.

"Oh nothing, I was just thinking that's all"

"About what?"

"Well I was just thinking, with the added weight you're starting to look like Granny" smiled Rhea

"Oh shut up" laughed Patty, launching the empty container at her sister.



Once the girls made their way to the mall they made their way through the throngs of consumers all out to get a bargain. They had decided that they should try and maximise their budget to get as many new clothes as possible, so designer labels were strictly off the table. They found a discount clothing store and got to work picking out a range of clothes both for the office and leisure.

The clothes weren't particularly stylish but they would suit the purpose. Rhea, being privy to the size of those trousers Patty had tried on Christmas Eve, purposefully picked out some smaller sizes just so she could enjoy the show.

When the girls retreated to the fitting rooms Rhea insisted on joining her sister while she tried on the clothes, getting an eyeful when Patty stripped to her underwear. It had been the first time Rhea had seen Patty in so little clothes since the summer.

Patty's belly now hung over her way too tight panties and had rolls that appeared as she twisted and turned, clumsily trying to get into the pants that Rhea had handed her.

"Dammit Rhea are you sure these are the right size?"

"What are they? Yeah a 12"

"Rhea! Come on, you know I couldn't fit into your 12's last time" blushed Patty

"Oh yeah, I forgot" sniggered Rhea "Try these, a size 14. Say you ever think you'd be a size 14?"

"No" said Patty flatly as she struggled into the pants "how do these look?"

"They're ok, a little tight though right?" replied Rhea as she stroked her hand over the expanse of flesh that bulged above the waistband of her sister's pants.

"You think I should go a size up?"

"Well I reckon you're a good couple of meals away from bursting the button right off those and I know you're sucking it in!"

"Okay" sighed Patty as she undid the pants and finally breathed out

"Well at least I know where most of my food budget is going" laughed Rhea as she slapped her sister's paunch. "I'll go and pick these up in a 16 and send someone in here to measure you for some new underwear. We should probably get you a girdle or something too, I don't want to have to keep coming back here shopping for fat girl clothes every week because you can't control your appetite."

"Yes okay" replied Patty, knowing there was no use arguing.

Rhea picked up a couple of pairs of the pants in a 16 as she said she would but also picked up a couple in size 18.

"My slim older sister in a size 18, I can't wait" laughed Rhea

Page BreakThe nine months between New Year's and the wedding were a hive of activity as would be expected.

Rhea had asked Patty to be her maid of honour, a position she had initially declined over fears she would look out of place in the wedding photos, a barb she had once thrown at her then larger sister but Rhea had managed to convince her and Patty threw herself into the role completely.

It was as if organising the get-togethers, bridal showers and of course the hen party, gave Patty a new lease on life, lifting her out of the funk she had been in. This however didn't seem to have had an effect on her now gargantuan appetite and she had continued to gain weight albeit at a slower rate but by the time the big day came around she was tipping the scales at 220lbs.

Of course this meant that she had to be refitted for her maid of honour dress but at least she didn't have to go alone, Rhea's continued active lifestyle meant that she had dropped further weight and need an alteration of her bridal gown. The formerly fat sister would become Mrs Rhea O'Hare at a slim 120lbs.

Patty stood at the front of the wedding party with her sister's bouquet in her hands clasped over her swollen belly that jutted out far past her breasts. Her makeup was done tastefully but there was no doubt Rhea had chosen the cut of the gaudy pink bridesmaid dresses to amplify the size of Patty's rear and thighs along with showing off her chunky, bare arms.

Months past and Patty would've been too embarrassed to stand up in front of everyone at the wedding but she felt reassured by the continued winks and lusty faces from her new boyfriend Mark who was in the gathering. They had met at Rhea's hen party months before and hit it off despite Patty getting flustered at the first male attention she had received in months. Mark made no bones about the fact he loved Patty's figure and helped her feel at ease with herself for the first time in what felt like forever. Mark didn't care if she gained weight, he just loved being around her and it really helped Patty put her experience with Garrett in the past.

The wedding went off without a hitch and the sisters shared a glance and a smile during the first dance, each knowing that this was the start of great things for both of them.

Before Rhea and Donny left for their Honeymoon the sisters sat down together and shared a slice of wedding cake.

"So, what's next for Mrs O'Hare?" asked Patty "Gonna let yourself go and get fat again like a proper newlywed?"

"Nah, you've got this big sister thing down to a tee" replied Rhea giving her sister a big hug, squeezing her back rolls as she did. "the best BIG sister a girl could ask for".
