It was also the very real, very shocked face of the same girl, peeking through the bathroom door and staring through the fogged glass of the shower.
"Holy shit," she whispered, before closing the door and quietly scampering away.
***
"There you are!" Beth called, thrusting an apron into Summer's hands. "Come on, you're helping me in the kitchen." She raised an eyebrow. "Did you check on your brother?"
"Y-yeah, I did," Summer stammered, still feeling a little disoriented from the weird conversation earlier. "He was still in the shower. I think, uh, he was tired after the flight... probably. But he should be outside in a few minutes?"
She had indeed checked on Morty, making sure he wasn't still trapped in his room. Dad was getting impatient, wanting to finally start decorating the house. Of course, it was already too late—only two days until Christmas—but in Jerry's mind, it wasn't really Christmas until the lights were up and flashing on the night of the holiday. Rick could decorate the house in under a minute but Jerry doesn't allow him about something about cheating.
"Ugh, seriously? Rick could get this whole house decorated in under a minute, but nooo, Jerry won't let him because it's 'cheating' or some crap. I swear, it's like he has this weird need to make everything harder than it has to be," Summer grumbled as she sorted through the kitchen supplies.
Mom and Dad are so paranoid about Rick ruining Christmas. I mean, sure, he could screw everything up, but it's just lights. How bad could it get? They're acting like if Rick so much as touches a lightbulb, we'll end up with, I don't know, a black hole in the living room or a time loop where it's always Christmas Eve.
As for Summer, she couldn't care less about all that. She'd had her own complaints—mostly about how Christmas preparations in their house always seemed to start way too late. The last few days before Christmas were always a blur of chaotic cooking and cleaning, and she wasn't exactly thrilled about it.
"Hmm," Beth said, squinting at her daughter as she sipped a coffee, clearly deep in thought. "Alright, just text Morty if Jerry asks about him again," she said, voice dripping with irritation. "I don't need you chasing after your brother when there's still a ton of stuff to do around here."
Without waiting for a response, Beth grabbed Summer by the arm and practically dragged her into the kitchen. Summer didn't resist; she just followed, her footsteps dragging slightly as they entered the kitchen, which was a chaotic whirlwind of flour, dough, and sizzling noises. The counter was covered in an explosion of flour dust, with dozens of flat, round pieces of dough arranged haphazardly. At the center of the mess was a large mixing bowl overflowing with a strange concoction of diced mushrooms, cabbage, and... something else.
"I'm sure you know the drill," Beth said with a dry smile, handing Summer a bizarre kitchen tool that looked like something you'd find in a mad scientist's lab—plastic, rigid, and far too complicated. "Don't overstuff it, or it'll explode or something. Just like dad's gadgets."
Summer barely grunted in response, rolling her eyes and taking the utensil. She bent over to the counter and scooped up the filling with the tiniest teaspoon she could find, placing it onto the dough, which felt somehow more dangerous than usual. She then pressed the handle, squeezing the dough into some sort of... cookies? No, definitely not a regular cookie. This was more like some alien hybrid of food and science experiment. She placed the completed dough into a bowl and stared down at it with a bemused expression.
Beth watched her from across the room, muttering under her breath about 'no more interdimensional cooking experiments with Rick'.
It was a boring and largely mindless chore. It wasn't long before she'd do it completely on autopilot, her head very much someplace else, as she processed the shocking revelation she had glimpsed only a few minutes prior.
Her brother really wanted her.
He had jacked off thinking about her.
He jacked off and came like she'd never heard any guy come while saying her name.
Her name! Summer!... His own sister from another dimension! But still his SISTER!
She gave out a quiet sigh, still in a state of disbelief. How long had she longed for something like this to happen? Too long, that much was certain. But today, maybe half an hour since he saw her again after many months, Morty was already noticing her in exactly the way she would like him to.
She was making serious headway with him, and she was doing it at an impressive pace. It was intoxicating to think that she was actively seducing her own sexy brother!
"You know, since Morty's finally back, it actually got me thinking," Beth said, a mischievous grin tugging at her lips. "It's been a while since I've seen any handsome young man walk through this door..."
"Huh?" Summer blinked, distracted and clearly not listening.
Beth raised an eyebrow, not letting her daughter off the hook. "Oh, don't act like you don't know what I'm talking about. I'm sure there are plenty of boys paying attention to you now—if they weren't already. I mean, I can think of two pretty obvious, pretty big reasons why..."
"Mom!" Summer groaned, turning bright red as she tried to hide her embarrassment, focusing on the dumplings in front of her.
Beth chuckled, leaning forward. "Come on, dear, indulge your old mom. Last I heard, you were dating some boy, uh, Kenny, right?"
"Ugh, Kenny's old news," Summer quickly cut her off. "We weren't even anything serious."
"Oh, serious enough for you to sneak out and stalk him," Beth teased, a saucy smirk creeping onto her face. "I remember you using the invisibility belt to break into his house. Oh, and then you had Nancy help you... because you were, what, sniffing his clothes?"
Summer's eyes widened, and she instinctively pressed down harder on the dumplings, as if trying to crush the memory into oblivion.
"You knew!?" she gasped, mortified.
"Summer, sweetie, please," Beth sighed, tapping the counter. "I know Nancy well enough to tell when she's lying, and I also know I raised you well enough to care about, you know, protection... Which you do, right?"
"Y-yes, of course!" Summer stammered, her face practically glowing red. "I mean... geez! What do you want me to say?"
"Come on, Summer, just spill it," Beth said with a knowing smirk, crossing her arms as she leaned against the kitchen counter. "Who's on your mind? You're obviously distracted. Don't even try to tell me it's all about school or whatever. We both know that's not it."
Summer's cheeks flushed a deep red. She bit her lip, nervously trying to come up with something that would get her out of the conversation.
"I... I don't know, it's early still, and I'm not sure if it's going anywhere," she mumbled, avoiding her mom's gaze.
Beth raised an eyebrow, not buying it. "Oh, I see. So there is someone, huh?" she chuckled. "Does he know?"
"Uh, sort of...," Summer admitted, hesitating.
Beth grinned like she'd won some sort of victory. "A crush! Well, get on it then! If he's worth your time, you better go after him before someone else does."
Summer sighed heavily. "That's easy for you to say, Mom..."
Beth leaned in, a teasing glint in her eyes. "What? You can't get the boys to notice you?" she asked with a smirk, giving her daughter a pointed glance. Even under her thick apron, it was clear that Summer's figure was... well, attention-grabbing.
"BETH!" Summer squeaked, her face bright red.
"Oh, come on!" Beth rolled her eyes dramatically. "Look, I get it. You want a guy to appreciate you for who you are, but the truth is, there are few things more effective than showing off what you've got. And, honey, you've got it!"
Summer gasped, completely embarrassed. "I... I know! And I've been trying..."
Beth shrugged, her expression turning slightly more serious. "Well, try harder. Sometimes, you have to be a little more obvious. Maybe in-your-face obvious. If the guy's dense enough not to notice, there's no shame in being shameless. Just... don't tell your dad I said that."
Summer stared at her, a bit stunned. "Huh... Alright, Beth. I think I get it..."
"Great," Beth said, as she regarded her daughter with a warm smile. "Now, let's try to focus on this a bit more, shall we? I'm already ten pieces ahead of you!"
They both laughed. Afterward, Summer did indeed pay more attention to the all-important task of making Christmas dumplings. Her concentration didn't last long, however, and soon her mind started to wander again.
But this time, she wasn't just thinking how awesome it was that Morty started to see her in a brand new, evidently sexual light. While she was ecstatic she managed to put this kind of thoughts in his head -- and make him hastily jerk off in the shower no less -- the busty teen soon figured out that she could perhaps try and go even further.
Maybe, when it came to her cute little brother, Summer should be much more than just a little shameless...
***
The remainder of the day passed very quickly, overtaken by a flurry of holiday chores.
After the incident in the shower, Summer didn't see her brother much at all. He and Dad had been busy with various activities outside, including those hundreds of electric lights that eventually adorned all the corners of their house.
Having dealt with that, they also picked up the Christmas tree which Jerry had ordered weeks ago -- the only part of holiday preparations that, by necessity, he had to deal with quite early. They hauled it inside and set it on a tripod, then proceeded to decorate it with the assortment of dusted-off ornaments that spent the last eleven months tucked away in the basement.
Beth offered some input there, although she could barely afford to stray too far from the kitchen. Summer was basically stuck there, too, helping her mother throughout the entire day of cooking. She was slicing vegetables, and grating cheese, and beating egg whites, and mixing whichever ingredients needed to be mixed, and performing any other task her Beth had asked her to -- all while trying to keep her mind away from daydreaming about her brother. She did end up receiving a few more playful scolds from Beth but the woman seemed too preoccupied with all the preparations to find her daughter's distracted state concerning in any way.
It was well into the evening when Summer was finally released from her culinary servitude. She retired to the bedroom and peeled off her clothes, yawning as she pondered whether to jump in bed and turn in early. Her legs felt stiff and her arms were quite tired. She didn't even think much of Morty at this point, the seduction of her brother seemingly postponed until later.
Yawning again, she stretched her arms overhead and spied her own reflection in the mirror. She saw a slightly frazzled but still gorgeous, astonishingly voluptuous girl, flaunting her body in a sexy ensemble of red lace lingerie. Her magnificent breasts were pushed up by both the bra and the lift of her arms, forming a luscious valley of mouth-watering cleavage.
She stopped in her tracks, tiredness leaving her in an instant, as she blinked a few times and looked at herself more closely. She followed the curved line of her bust and hips, shifting her weight coquettishly, smiling and giggling and feeling more confident and sexy than ever. She admired her delectably curvaceous body, harboring no more doubts that Morty would find it anything but completely mesmerizing.
Then, a sudden inspiration struck the burgeoning temptress. Rather amusingly, it hearkened back to Beth's earlier advice. Feeling naughty and more than a little frisky, she grabbed her phone and pointed it at the mirror. She snapped several raunchy selfies, in various seductive poses that did a good job of highlighting her impressive bosom.
But she wasn't totally pleased with any of them. They were hot, obviously, but didn't have quite the impact she was going for. And since there would be no second chances, Summer knew she couldn't settle for anything less than perfect.
She had to do it right.
"Jesus, I can't believe I'm about to..." her whisper trailed off, and she sighed. "Ah, fuck it! Why not?"
From the depths of one of her less-used cabinets, she dug up a rather embarrassing contraption. It was a selfie stick: a metal rod about three feet long, with a clamp to affix your phone which you could then point at yourself and snap a self-indulgent photo. She crawled on the bed and used a heavy pillow to keep the stick in place, protruding just above the headboard, then placed her phone at the other end and pointed it at the mattress.
She then lay underneath, positioning her body so it fit in the camera frame. With a deep breath, she started the recording.
At first, she was nervous. She didn't dare to say anything. Instead, she bit her lip and forced herself to smile at the camera, letting out a long, breathy sigh. Moving up over the flat tummy, her hand reached to caress her round boob, rubbing the embossed material of the crimson lace bra. It dipped further up, one or two fingers running over the flawless skin of a teasingly exposed cleavage, side to side, venturing even into the dark and mysterious canyon between the two glorious mounds.
Slightly more bold now, Summer pushed the same breast towards her chin. She purred as its top outline became clearly visible; a smooth indentation in her pale skin, betraying the volume of the large sphere, firm and shapely, but also pliant and perfectly squeezable.
She did the same thing with the other luscious globe, separately from the first. Meanwhile, her other hand was gradually straying past her navel, toying with the lacy hem of her red panties. The thin rubber band slapped her flesh as it rebounded, eliciting a husky moan and ending up just a little below where it used to be. She ran a finger over the frilly lace, feeling the tactile sensation of its myriad tiny bumps and holes.
She was taking it in. Playing with it. Hesitating.
Her heart beat faster now, breaths becoming shallow and hasty. She finally dug underneath and reached the forbidden place, deep between her legs and past the smooth stretch of pubic skin. She let out a lustful whimper, as her fingers made contact with the hot and musky treasure. The engorged nub pulsed eagerly in the gentle pinch of her fingers, making her sigh in pleasure as she squeezed and caressed it softly. She instinctively synchronized the touches with the rising tempo of her breathing, and each time she exhaled the breath would cover an airy expression of her growing arousal.
She was really turned on now. Moisture leaked out of her glistening pussy, soaking into the scarlet panties. Their color ran dark enough that the growing wet patch remained difficult to notice, but she felt it with her fingers, as she did the soaked labia. One, two... They went into her sopping wet depths, and she had to bite her lip again not to groan in raw, primal joy.
Instead, she gasped. This unexpected jolt of pleasure clued her in to the fact that she'd been masturbating. Many thoughts ran through her mind, and many feelings came and went. Embarrassment was among the first but it too had gone rather quickly. The one feeling that remained was the same roaring arousal, along with a firm conviction to put it to a better use.
Even better than making a hot video for her brother, that is.
"Mhm," she purred, withdrawing the hand that was in her panties and giving out a sultry giggle. "Whoops," she added seductively, bringing it back up and laying it on her sizeable chest.
It was time for the final act. Summer cupped both her breasts now, mashing them together and creating a jaw-dropping valley between the two enormous pillows. She brought them almost to her chin, giving the camera a smoking hot look, then held them like that for a long second and winked. Once released, they slid down with a luscious jiggle, threatening to spill out of their meager lacy confines and expose the full splendor of the girl's incredible bosom.
One last smile and she stopped the recording, falling on the mattress and panting from excitement and also the lingering arousal. Still supine on the bed, she unhooked the phone from its harness and began tapping on it furiously, licking her lips and rubbing her thighs together.
Summer: Hey bro! I'm still waiting for your opinion!
She sent the message to Morty, then switched back to the video she had just made. She watched it from start to finish, and she found that it only increased her already surging horniness. If there was any embarrassment left, about what she had set out to do, it couldn't possibly get through the thick cocoon of lust that enveloped the eager blonde.
To further pass the time she decided to edit the video, cutting out the few seconds at the beginning and a short sequence right before the end. While she was doing this, fiddling with the camera app, his reply finally came.
Morty: About what?
Summer: Whether or not I've got the right assets, of course ;)
It felt deliciously naughty to send this response; a shiver ran down her spine when she tapped the button. Indeed, she felt bold enough that she figured she needed to clarify -- to make it absolutely, unquestionably clear which territory she was threading.
Summer: To be a content creator like your ex!
She started watching the video once again, and she was more and more tempted to reenact what she was seeing. Her pussy throbbed with unquenched need, begging her to finish the abruptly ended session of shameless self-pleasure.
Morty: Wow! Are you serious?
She giggled as she typed the response, but another text came before she sent it.
Morty: I'm not gonna answer that!
Here it goes, she thought, taking a very deep breath and readying her thumbs.
Summer: Why not? Did you forget how I looked already?
Quickly now, before he can respond...
Summer: Maybe you need some reference material?
Tap the paperclip icon and select the video...
Summer: Here, how about you take a look at this? ;)
Press the button and... that's it; Summer finally exhaled. It took a few more seconds still, of her staring at the rapidly filling blue bar before the deal was truly sealed.
She had just sent this racy, practically obscene video to her brother.
***
One door down from hers, Morty lounged on a small sofa in his bedroom. He was holding the remote and mindlessly flipping through the hundreds of TV channels, undecided whether or not he wanted to actually watch anything.
He felt pretty beat, after the ordeal with house decorations and the Christmas tree, but not nearly enough to simply crash on the bed and sleep. He took another shower and changed into a yellow shirt and boxers, both quite snug on his nicely built frame. Morty was no athlete, but he wasn't ignorant of the benefits of regular workouts after being in intergalactic conflicts. Many ladies would agree he was very attractive, including his ex-girlfriend Jessica, but the young man wasn't currently interested in mingling with her or anyone else of the opposite sex.
That was the stance he'd say he maintained. Until today, it might've even been true. What changed it -- of all possible things that could've changed it -- was coming home and meeting his older sister Summer.
"Calm down, you idiot," he scolded himself. "You're pathetic!"
It hadn't been too difficult when he still toiled with Jerry. He'd been helping the old man make this Christmas as special as any other, and that kept his mind sufficiently occupied. But now that he was idle again, the inappropriate thoughts came back very quickly. They didn't want to leave him.
"It's your sister..."
And quite frankly, he wasn't sure if he wanted them to leave him.
"But seriously... What was it with all that crap about Jessica?"
It was a question he posed to the quiet and empty room. He didn't expect an answer. But to his surprise, the answer did come -- in the form of a blinking light on his phone.
He read her message, and his eyes went wide like saucers.
Throughout the whole exchange that followed, his body barely moved. He sank into the sofa and stared at the dancing dots, typing the texts quickly and practically without thinking. He was still guided by a lingering sense of propriety, of what should and should not happen between a guy and his sister, but there was only so much that even a decent man like him could take.
There was only so much he could do when his sister sent him a video like this.
"No fucking way!"
He watched it once, and his jaw dropped on the floor. He watched it again, and his cock had visibly tented his boxers. He watched it one more time, and he was fully erect and pulsing, as he seriously contemplated jacking off to the hot, scantily clad body of his stunning young sister.
