[Contains Male and Female Weight Gain]

As fun as it had sounded for Jaune and Pyrrha to squeeze into their old swimsuits for their beach double date with Ruby and Weiss, the novelty was starting to wear off a little bit. When the beaches were closed last year, along with just about everything else, Jaune and Pyrrha decided that it was finally time for them to properly let themselves go and get as fat as they truly wanted. Needless to say, they were very successful and were dealing with the effects of it right now.

Jaune was sporting what was probably very close to a dad bod, despite probably being a decade or two too young for that. He was looking chunky all over, with a solid layer of fat covering everything, but the main focal point for his fat was his gut, which he and Pyrrha worked to make nice and round as it covered up the abs he used to have. It was hanging over the waistband of his dangerously tight white with yellow trim swimming shorts. His mighty thighs and his prominent posterior, made up of decent portions of both fat and muscle, were the main concern right now, as he was worried that moving the wrong way would lead to him splitting his shorts and embarrassing himself more than he was entirely comfortable with, and that was really saying something, considering that he and his girlfriend were exhibitionists enough to show off their newly fattened bodies in clothes that were far too small to comfortably contain them.

With Pyrrha, she was equally chunky all over, but she had not kept the level of muscle that Jaune had, meaning that all of her fat was a fair bit softer. From her jiggly thighs and arms to her flabby, rolling belly and bountiful bouncing breasts, every move she made, sometimes even a move as small as a deeper than average breath, would make at least something on her fattened body wobble like jelly. Her belly poured over the waistband of her maroon and gold bikini bottoms, while her blubbery behind swallowed the fabric between globular cheeks. Her breasts were barely covered by her matching bikini top, with them sneaking out above, to the sides and below the fabric while her nipples were almost popping out and making her indecent, something she would enjoy doing in front of Jaune more if not for the likely repercussions. The knots holding the stringy bikini were barely holding on, as they had to go around a lot more bod than they needed to when Pyrrha first got this bikini, making Pyrrha nervous about the possibility that they'd undo themselves.

Right now, as they waited for Ruby and Weiss to arrive at the beach, they were working on putting sunblock on each others' broad, soft backs. Pyrrha had already done Jaune's, likely enjoying massaging the sunblock into Jaune's back as much as Jaune enjoyed Pyrrha's thorough touch. Now, it was Jaune's turn to cover Pyrrha's back. He straddled her wide, womanly hips and leant forward to get to work. He tried to ignore the fact that his crotch was pressing against Pyrrha's plump and pillowy posterior, and that his fat gut was resting on the small of Pyrrha's back, but judging from the noises slipping from Pyrrha's lips, Pyrrha wasn't ignoring him.

"Hey, uh, Pyrrha, you might wanna dial it back a little until we get home," Jaune warned, doing his best to hide how much he was liking what he was hearing and feeling. Of course, his warm member pressing against his shorts and Pyrrha's backside was definitely betraying him.

"But I am dialing it back, you big handsome stud," Pyrrha purred, gripping her towel as her face went red.

"You know, sometimes I think that maybe we're a little too into this fetish," Jaune replied, a little quieter this time, in case anyone was listening in on the couple.

"We both know you won't be complaining about this tonight," Pyrrha teased. Now it was Jaune's turn to go red.

"Hoo, boy, you're not wrong," Jaune got out, through his flustered voice cracking. If they weren't so public right now, Jaune knew they wouldn't be waiting until tonight, or even at all.

Once Pyrrha's back was nicely covered in sun block, the pair lay on their fronts to catch some sun. With their extra fat, this definitely didn't feel the same as it used to. For Jaune, his firm and fat gut propped him up a bit, which took a bit of getting used to, while for Pyrrha, her soft belly and breasts spreading out as she rested her increased weight on them was an unusual, but still enjoyable sensation.

After a little while of enjoying the sun's rays and relaxing, a familiar couple of voices pricked up their ears.

"Aw beans. Weiss, I think we missed them," a younger voice said.

"Ruby, do you really think Jaune and Pyrrha would abandon us?" Weiss replied. Jaune and Pyrrha sat up and looked at the talking couple, who were likely not even ten meters away at this point. Even if they didn't recognise the other couple's voices, they would have immediately recognised their appearances, with the two young ladies as slim as ever and with Ruby's red and black board shorts and rash shirt and Weiss' one piece white swimsuit with extra frills around the hips being instantly recognisable. Jaune and Pyrrha shared a look of acknowledgement between themselves, the fact that their new sizes made them unrecognisable to their friends getting them excited. Pyrrha waved to the other couple while Jaune called out.

"Ruby! Weiss! We're over here!" Hearing their names, the other couple turned and saw Jaune and Pyrrha. Their eyes went wide with undeniable surprise.

"Jaune? Pyrrha?" Ruby exclaimed. "You two look..."

"Well. You look well," Weiss tactfully interrupted, before Ruby could stick her foot in her mouth.

"Thank you, Weiss. We did our best to relax while we were cooped up inside," Pyrrha said, leaning back and pushing her expanded breasts and belly out, putting them on full display.

"Er, that's... good to hear," Weiss replied, trying her best to avoid mentioning the elephants on the beach while Ruby set up a big beach umbrella, occasionally sneaking peeks at the corpulent couple. Of course, Jaune and Pyrrha knew that, as much as Weiss and Ruby were trying to hide it, they could see their gains as clear as day. Needless to say, they were liking the attention. All they had to do now was to keep it cool until they were home. After that, they were going to have a very fun night.
