Pepper and Perilla were a pair of orange cats, brother and sister, who were really enjoying sharing a room together back at Pepper's family's home! When he moved back in with his family after going out in the world a bit, he and his sister got to share their mom's old big bedroom together, and it was working out really well for the two. What was fit for a mom and dad also seemed to be just as nice for a brother and sister...

"The shower's all yours, Pepper..." Perilla smiled, as the chubby orange cat walked into their master bedroom in just a towel. Pepper's cheeks blushed as red as his eyes as he looked at his sister, dripping wet in almost no clothing at all!

"Thanks," he replied calmly, trying not to get too giddy over seeing her like this. With both of them in their twenties, they were pretty calm and casual, they'd seen it all by now, so Perilla wasn't even really that shy about changing clothes around her brother. It's not like she did it right in front of him face-to-face! The chubby cat girl picked out her shirt for the day, and dropped her towel, giving Pepper a view of her backside and butt. He couldn't help but whisper to himself, "Meowza..."

It was nice to have a relaxed approach to nudity as adults sharing a bedroom together! But... an ass was an ass, and Pepper enjoyed seeing hers, even if it was his sister's! Or... maybe he liked seeing it even more because it was his sister's. It wasn't really something for her brother to be looking at... but there it was. It was hard not to observe and enjoy! Just plump orange kitty cheeks, and knowing his sister's kitty was on the other side of that... well, it was hard not to feel a little frisky!

Perilla slipped on her white shirt, but due to her recent shower... it was a little wet. Pepper sure noticed as she turned around. Bits of her shirt were a little transparent... especially two little spots up in front of her chest! Those circular areas looked just a bit darker than the rest of her shirt... and she seemed to notice Pepper staring at them. She looked down to see what he was seeing, and noticed that, not only were her nipples a little more visible at the moment... they were also starting to poke out too! It felt weird, knowing that even when she was clothed, her brother could see her breasts in some detail. She looked back up at him, and noticed him still smiling and staring right at them, with a slight look of wonder.

"Pepperrrr..." Perilla called out to him, hoping to snap him out of his trance. The brother cat realized what he was doing and snapped up! 

"Oh! I shooould go shower too..." He tugged his shirt down over his lap, grabbing a towel as he turned to the bathroom door. He wasn't going to mention anything about what he was just doing and move on! Though, he did feel a little funny today... so he went ahead and tossed off his shirt while his back was facing his sister. Nothing wrong with her seeing a little male backside! ...Well, except, now she also had a view of what Pepper was enjoying earlier. She could see her brother's naked buttcheeks! And sure, they often all just wore shirts, but it usually covered up most of this stuff, and it sure felt different from when they were completely nude, with their butts and bits all out completely!

At the least, Perilla was glad she wasn't the only one on show today. Maybe Pepper even did that to help even things out and make his sister feel less embarrassed, or maybe her accidentally being on show was helping make him feel a bit more comfortable with their situation too! It was going to be pretty difficult for the pair to share a bedroom together and not end up seeing a bit of male or female nudity.

Surely their mom knew that was a possibility! The cost of coming back home to live with family, and share a room with your sister, might be him seeing his sister's genitals now and then, or his sister seeing his! When they made this arrangement, their mom was probably just glad two siblings were willing to share a room together. Did it cross her mind how they might have to deal with dressing together, showering within proximity of each other? Were they ever sharing the same bed with how their schedules worked, sleeping together? And if so, did they mind? Luckily a lot of those unspoken questions never really came up, and instead of being a problem, they were things the two siblings seemed to sort of enjoy...

As Pepper slipped into the shower, his thoughts slid to his sister, what he'd just seen of her, and what else he might be able to see of her sometime... he couldn't help but feel excited, and get a little touchy as he enjoyed thinking of the female family member in just the other room! Masturbating to his sister when she was so close by was a little fun... he hoped she'd be flattered if she knew, rather than upset or weirded out!

Perilla on the other hand... wasn't much different! As Pepper got in the shower, the door was cracked open just a bit, with Perilla on the other side. She listened in, which, sure it was a little weird for the chubby nerdy feline to be doing... but curiosity got to the cat! She wondered if her brother would be enjoying himself while thinking of her in there... though, even if he wasn't, she might be enjoying herself imagining it if he did... She kept her paw busy between her chubby sisterly thighs, rubbing and touching herself while thinking of her naked brother in the shower. It only got better when she heard him breathing louder, and making some strange little noises in there, almost as if he was giving some part of his body a really intense scrub...

"He's definitely doing it..." she growled to herself. It was just sort of obvious when someone in the room next to you was fapping, especially in a shower with a bit of echo and water sounds to give it away! "And it was just moments after looking at me..." she looked down at herself, rubbing over her shirt where her nipples were, almost thanking them for doing a good job exciting her brother! And touching them helped excite her too. Perilla huffed quietly as she dug deeper into herself, picturing her brother in the shower, fantasizing about opening the door and joining him. 

"W-wait, that'd be dumb, I just took a shower!" She laughed to herself. M-maybe he wouldn't notice? No way, it'd be the first thing he'd say! He was a very observant cat. Though, she hoped he wasn't observant enough to hear her fapping! ...Maybe, if he was masturbating, and heard her masturbating as well... maybe she could guarantee that he was more likely to fap to her? Maybe they'd know they were fapping together! Or would that cross the line? Would he tell her to stop? Maybe it'd turn him off if he heard his sister masturbating, and he couldn't enjoy doing it to... whatever he was thinking of in there.

"Mmmff...!" She went ahead and did it anyway! And... she heard Pepper pause in the shower. His loud "scrubbing" session stopped all of a sudden. She made another little embarrassed whimpery noise, as if she knew she was being too loud while playing with herself...

Suddenly, Pepper's shower noises picked up! Like he was trying to bathe himself in a rush! Perilla was thrilled. She was SO sure Pepper was in there masturbating to her. So, she kept going too, rubbing and groping her body, feeling herself all over, her chubby breasts and belly bouncing around, even thinking of how it would feel if it was her own brother doing this to her instead. She purred and groaned, not caring as much about making noise, and not sure Pepper could really hear it anyway. She didn't wanna go on too long and get caught though! ...Not by Pepper OR their mother. She pushed herself to the edge and let out one more feminine moan as she slumped against the door. "Rrrrrreoowww!"

Perilla accidentally leaned against the door too much, and shut it closed with a bit of a bang! M-maybe it muffled her orgasming moans a little? As she panted, out of breath, resting against the door with her inner thighs all sticky, she heard a few moans from her brother on the other side of the door too!! Her jaw dropped, it sounded like he was doing the same exact thing!! She couldn't be too sure, but... maybe her sexual sounds got to her brother's ears after all. She gave a big toothy smile just thinking that it had to be the case... she was really happy about it! She hoped he enjoyed himself as much as she enjoyed herself too...

The older sister pictured her brother was resting naked in the shower too, both of them catching a sexual breather with just the door between them. She thought it seemed cute, imagining him all tuckered out like that, figuring out how to clean up any cum left in the shower that he released while thinking of his sister... she even thought it might be fun to open the door and just see how he was doing. Though, she didn't want to cross the line or anything. She'd just enjoy what they might have just had together...

After a few minutes, she got up and straightened up her outfit. She looked down and saw her crotch, which was all clean and smooth just a bit ago, was now quite roughed up, with odd bits of fur sticking together between all the wetness she left behind! She went to go get her towel, and rubbed around her crotch and inner thighs, cleaning everything up and straightening out her fur so no one would notice. She had one foot on the bed so she could more easily rub and clean her chubby thighs. This did leave her pussy completely exposed and visible. It would be a real shame if Pepper opened the bathroom door and saw that!

She looked down at her chubby, sisterly slit, and gently rubbed the towel over it with relief. Everything was looking fine and normal again! No way Pepper or her family would know what their sister was just up to...

Creeeeeeak...

The bathroom door slowly opened, and a very flustered brother cautiously walked out. He wasn't sure what to expect outside the bathroom door! His sister was looking pretty normal, but... he did notic her with a towel being held right up against her crotch.

"...Sorry about the door!" Perilla squeaked, in her nerdy little voice, a little lower and huffier than usual after what she was just up to.

"Oh, it's fine..." Pepper just stood in place, this time his eyes were locked on his sister's towel being held right up against her vulva! She was just barely covering it up! Or... maybe cleaning it up? ...Pepper had to wonder, was she cleaning it after the shower, just rubbing for fun, or... were those sounds he heard outside the shower really just his sister moaning and pleasuring herself? Maybe this was her cleaning away any evidence... he couldn't say for sure! Not like her wet towel would give away any answers.

Perilla just followed his eyes down to her little slit again. It was a little odd to be caught rubbing it, even for possibly clean reasons, right in front of him! And... if she took her hand off it, she'd just be... revealing her chubby pussy to her brother. ...She wanted to! It'd be nice to! She could picture a big smile forming on her brother's face as she just moved the towel away and showed him her chubby lower lips. He'd love it! Maybe then he'd take off his towel and show her what he had too! They'd soak it all in for a moment before seeing if they wanted to go even further together... Right? Well, she thought so anyway. Maybe they would!

But... well, as horny as she was, she was also a little shy sometimes, and it was hard to be a bold little nerd some days. So, she just took her leg off the bed and turned her back to Pepper as she gave herself a few more rubs, all before tossing her towel.

Pepper didn't want things to feel any weirder! So he just turned, took off his own towel, and fetched his own shirt in the drawers nearby! Perilla looked back, and enjoyed the same little view she gave her brother earlier. It was kind of nice having a nude guy in her bedroom! She liked the thought of that... and well, even if it was her brother, she probably liked it more because it was him! 

One other nice thing with her brothers was, when they're nakie from behind, she could still see their plump and fuzzy little cat balls jiggling around between their thighs. It was nice to see a little something, anyway!

"Hey Perilla..." Pepper spoke in a deeper, serious voice than usual.

"Yes Pepper?" the nerdy cat girl gasped, wondering what he wanted.

He turned around, all dressed in his red and yellow top, holding a towel in front of his crotch in the same way Perilla was a moment ago! He even stood his leg on the bed, quite on display in front of her (well, aside from his towel covering up the goods, anyway.)

"Pepper!!" Perilla growled, seeing her brother was teasing her about the naughty towel touching she was doing a few minutes ago. "I-I was just...!"

Pepper smirked, and spoke up so she didn't have to make up some excuse. "I've got something we can both enjoy doing together..."

Perilla felt a pit in her stomach. Was he... was he talking about them fapping together??

"Pepper!" Perilla whined, yet, she wasn't bold enough to admit anything out loud! Her teasy brother's toothy grin grew as he dropped his towel in front of her.

Perilla's mouth dropped open. Right inbetween his legs, her bottomless brother, all spread out, without any pants or underwear on... somehow, he fit a copy of one of their favorite games right in front of his crotch. That towel dropped to reveal a VIDEO GAME they could enjoy playing together! ...Definitely different from what Perilla had in mind.

"...Oh brother..." she sighed, feeling teased by her naughty and playful sibling. She looked at what game he propped up in front of his penis. "Sure, let's go roll around in Lordran together~"

Pepper chuckled, and tugged his shirt down to cover his lap, before picking up the game, and grabbing his sister's paw so they could go play together. 

Perilla couldn't help but wonder, were they ever going to talk about what happened? Were they both aware? Was it what she thought? Well, until she wasn't too shy, and until her brother was done teasing her, she might not know for certain...

As they walked out of the room, Pepper cheered, "Praise the sun, but don't forget about the moon~" HONK! Perilla felt her younger brother grab her ass, squeezing his sister's plump butt cheek out in the open!

"Pepper!" She turned to yell at him, only to get a surprise kiss on the cheek, before watching him dash downstairs. It sure stopped her in her tracks! But, she was starting to realize how fun it was going to be, having her teasy, silly little brother living at home with her again. 
"Oh Pepper~"
