Summer banged on the door, her metal claws scraping against the wood.
"Morty! Are you in there? Stop jerkin' off! I need to borrow your printer!"
She tapped her claws impatiently against the door. No response. Typical Morty. She raised her hand to knock again, this time ready to claw her way through, when the door swung open. Morty's exasperated face appeared on the other side, his black eyes glaring at her.
"Jeez, Summer! Can you not use the claws on the door? Rick just fixed the damn thing!" he groaned.
Summer held up her flash drive with a grin. "I just need to print out my pictures. Is that okay, little bro?"
He sighed heavily, stepping aside. "Sure, come on. Just make it quick, and no... slicing anything, alright?"
Summer sauntered in, retracting her claws with a snikt.
"What kind of greeting is that?" she teased as he shut the door behind her. "Is that any way to say good morning to your awesome sister?"
Morty rolled his eyes. "Like you're one to talk, Summer. You almost gave me a heart attack scratching on the door with those things."
Summer flexed her arm, the faint glint of adamantium showing beneath her skin. "Maybe if you stopped masturbating all day, your heart could handle a fucking knock on the door."
Morty's face tightened. "Okay, first of all, screw you. Second, those aren't normal hands, Summer. You almost stabbed me last time."
"You didn't think the claws were just for show, did ya?"
"No, no, I'm good. I've seen the demonstration."
Summer smirked. "Hey, it was an accident. You know I didn't mean to slice you." She popped a claw for emphasis. "You didn't believe I was stronger than you. I was defending my pride, little brother."
"Yeah, well, I learned my lesson." Morty shook his head. "Just... no slicing anything this time, okay?"
Summer shrugged. "No promises."
She plugged in her flash drive and sighed dramatically. "Stupid thing. My printer won't even work because I'm not using 'authentic' ink cartridges. Like, seriously? Who do they think I am, Elon Tusk? You know how expensive that crap is?"
Morty looked at her, confused. "Wait, your printer knows you're not using the right ink?"
"Yeah, it's got this stupid chip in it or something. Every time I try to print, it's like, 'Sorry, you need genuine overpriced cartridges to use this feature!' It's just black ink. How hard can it be?" Summer grumbled, frowning as the screen on his printer lit up.
Morty raised an eyebrow. "Why don't you just get the real ink?"
"Because it's highway robbery, Morty! They charge more for a tiny bottle of ink than you'd pay for, like, dinner for two at Shoney's! I'd rather fight an army of Ricks than pay that much for ink." Summer crossed her arms in frustration. "The knockoff brand works fine! It just won't let me print!"
Morty chuckled. "So you decided to terrorize me in the morning instead of fixing your own problem."
Summer raised an eyebrow. "Oh, please. Like you ever fix your own problems. You just bitch until Grandpa Rick fixes 'em for you."
"I-I don't do that every time."
"That's exactly what you do."
"Yeah, whatever. Just hurry up before you end up slicing something out of frustration."
"No promises, Morty. So can I use your laptop or not?" Summer smirked and grabbed the bottom of her shirt. "How about a trade, then? Tits for prints?"
Before Morty could react, she yanked her shirt up and gave her boobs a quick jiggle. His eyes went wide, his stare immediately dropping to her bra. The little pervert was adorable when he got flustered.
"Come on. That's worth a print job, right?"
"Fine, fine, you can use my printer..." Morty sighed, raising his hands in mock surrender, though Summer noticed he wasn't exactly trying to block his view.
"Thank you!" She pulled her shirt back down, still smirking. "And stop being so dramatic. You couldn't even see anything. I'm wearing a bra."
Morty gave her a deadpan look. "Summer, I-I don't think that even counts as a bra. That thing's basically an eye patch with straps."
Summer tugged at her neckline and glanced down. "Oh, shit. Forgot I had the 'Gettin' Lucky' one on. Laundry day."
Morty's eyebrow shot up. "Wait, you wear lingerie on laundry day?"
"Well, it's not like I'm wearing it on any other day lately." Summer rolled her eyes. "Besides, everything else was dirty. Unless you'd rather I skip the bra altogether? My, my, how scandalous..." She toyed with the hem of her top, enjoying how uncomfortable he was getting. "But if you want a view..."
"Please keep your bra on," Morty said flatly, even as his face turned red. "No one wants that."
Summer laughed. "Relax, Morty. You're such a prude sometimes."
"Spoilsport," she muttered.
She dropped into the chair at his desk and plugged her flash drive into the laptop. She dug through her files until she found the photos from Atlantis she needed to show off and hit print. The printer buzzed to life beside her, whirring and clicking as it dragged in the first sheet.
"So... how's Jessica?" Summer asked, leaning back in the chair while the printer did its thing. "Saw you guys outside the dining hall last night. Were you on a date? Did you two kiss?"
"Yeah... I think so," Morty mumbled, leaning against the desk, his face flushing a bit. "I mean, she's smart, funny... and she listens to me when I talk about all my, you know, geeky stuff. It's... it's nice. Honestly, I could just sit with her for hours, not even doing anything, just... holding hands. Our dates are pretty much perfect... almost."
"Almost?" Summer asked, raising an eyebrow.
Morty's smile faded a little. "Yeah, well... it would've been perfect if Rick's bullshit fucked over the whole date."
Summer snorted. "The Nimbus thing?"
"Yeah. Except while you were off getting that stupid shell, Jessica got dragged through the portal to a fucking Narnia dimension."
Summer looked over at him. "Really?"
"Yeah." Morty rubbed the back of his neck. "Those Narnia assholes froze her in this crystal thing. She couldn't move, but she was awake the whole time. And with how fast time works over there..." He shook his head. "I don't even know how long it felt like. Basically forever."
"Jesus."
"Then I finally get her out, everything's over, and I ask if she still wants to watch the movie."
Summer stared at him. "You still asked her?"
"What was I supposed to do? That was the whole fucking point of the night!"
A grin started pulling at Summer's mouth. "Okay. And?"
Morty looked away. "She gave me this whole speech about eternity and existence and all this cosmic shit, then said we should just be friends."
Summer was quiet for half a second.
"Don't."
Her grin widened.
"Summer."
"So Jessica spent eternity thinking about the universe and still came out of it not wanting to date you?"
"Fuck you, Summer."
She laughed. "Jesus, that's brutal."
"Yeah, well, apparently she's a time god now, so whatever."
Summer's laughter stopped. "Wait, what?"
"Some guy tried talking to her afterward, and she told him to fuck off because she was a time god."
Summer stared at him, then cracked up again.
"Oh, come on!"
"Sorry, Morty." She wasn't. "You finally get somewhere with Jessica and she fucking transcends you."
"I hate you."
"Yeah, yeah." Summer turned back toward the printer, still grinning.
Summer had stopped listening. Her attention drifted back to Morty's laptop. The browser was already open, and boredom got the better of her. She clicked into his history and started scrolling.
The first few titles told her pretty much everything she needed to know.
Cute Ginger Giving a Great Blowjob.
Good Morning Blowjob.
Amateur Blowjob Contest.
She bit her lip, trying to hold back a snicker. Guess she knew what Morty's kink was now.
The video opened on a young woman welcoming some guy into what was supposed to be a massage parlor. Summer was already starting to doubt how legitimate the place was, mostly because the masseuse was wearing a kimono short enough to count as a miniskirt and clearly didn't have a bra underneath it. Or panties, Summer realized when the woman bowed to her client.
Morty stopped talking and looked over at the laptop screen. His face quickly turned as red as the masseuse's lipstick.
"H-hey!" he stammered, trying to close his laptop. But she was faster and pulled it away. "Quit it! What are you watching?"
"You should know... I found it in your history. It looked interesting..."
He averted his eyes. "Why were you going through my history? I thought you were printing your pictures?"
"I got bored! And I just opened your browser... It's not like I wasn't expecting to find porn."
She glanced back at the screen. The masseuse was helping the customer out of his clothes and onto the massage table. Her dark brown eyes roamed over his muscled and tattooed body.
"Turn it off..." Morty pleaded.
"Oh, come on, don't be such a pussy. Watch it with me." Summer was genuinely curious now. What kind of lame porn did Morty watch when he was alone in his room after a breakup?
Morty blinked at her. "Watch it? With you?"
"Yeah, with me. What's the big deal?"
"Uh, well, let's see, it's porn, aaaaaand...it's porn."
"So?" Summer glanced at him. "You lived in the same house with me and Hemorrhage for three weeks in that post-apocalyptic shithole. Don't suddenly pretend you have boundaries."
"I didn't watch you guys have sex!"
Summer smirked. "No. Heard us, though."
Morty's face reddened. "That's not the same thing!"
"Close enough."
"No, it's really not. And movie sex is usually fake. This is, you know..." He gestured awkwardly at the laptop. "Actually happening."
"Porn is even faker than wrestling." Summer leaned back in the chair, still watching him. "Come on. I'll give you a blowjob if you watch it with me... Please? How long can you resist?"
Morty stared at her.
Summer's smirk widened. "What? Suddenly you need time to think about it?"
He hesitated, and she could practically see whatever argument he had been preparing fall apart.
"Why do you even want to watch it, geez?" he finally asked.
Summer did her best to look innocent. "I want to check my technique. Or..." She let her hand brush lightly against his thigh, laughing when Morty immediately jerked back. "You could tell me what you think."
"Okay, fine, I'll watch it with you if you promise to not mess around."
"Promise."
Summer gave up the chair, and Morty sat down. She stayed behind him, resting her hands on his shoulders just as the guy onscreen rolled over on the massage table. The tiny towel covering him wasn't doing much to hide the massive erection underneath.
Summer stared at the lucky bitch for a second.
Hemorrhage and Ethan hadn't exactly been impressive in the size department, while this woman had somehow ended up with something nearly a foot long and was getting paid to be railed by it.
She started rubbing Morty's shoulders as her cunt grew warmer, both of them watching the screen.
"So..." Summer leaned a little closer, her mouth near his ear. "You really like blowjobs, huh?"
He was silent for a moment. Summer wished she could see his face. Judging by the back of his neck turning pink, though, she had a pretty good idea what it looked like.
"I mean, y-yeah," he said finally. "Don't all guys?"
"Not just guys." Summer smirked. "I like them too."
Morty turned his head and looked up at her, cheeks still flushed. "Wait, seriously?"
"Seriously. I love having a guy's cock in my mouth. Feeling it get hot and hard against my tongue, feeling him twitch between my lips when he's getting close..." Summer's mouth curled into a small, satisfied grin. "And when he finally cums and I get to swallow every last drop? Yeah. I fucking love that."
Her fingers slowly curled into a fist without her realizing it.
"There's just something about having his cock completely at my mercy. Like, he can act as tough as he wants, but once I've got him in my mouth, I'm the one controlling how fast he gets there, how hard he cums, whether I stop right before he loses it..." Her grin widened. "It's kind of a power trip."
For a second, Summer got lost in the memory of past hookups, the salty taste, drugs, the way a guy's whole body would tense right before he spurted jizz.
Then she realized how much detail she had just volunteered.
She cleared her throat.
"Anyway." Summer looked down at Morty. "What do you like about them? Besides, you know... the obvious."
"Me? It...geez...this is so embarrassing..."
"No, it's okay. Keep going. I'm curious."
On-screen, the masseuse slipped a hand beneath the towel, a wicked little grin spreading across her face. Summer glanced down without thinking.
Morty's jeans were tented hard, a thick ridge pressing along his thigh.
Jesus.
He'd probably look pretty good stretched out on a massage table with nothing but a towel over him. Her eyes lingered a second too long. Since when did he get so big down there? How much would he cum if someone really worked him over? She could have asked Jessica but that moron…
Summer blinked and dragged her attention back to the screen.
Okay. Nope.
She really shouldn't be thinking about her brother like that.
Morty took a breath. "I don't know. I guess it just feels more... sexy? Like, it's hot when a girl actually wants to do it. Not because she has to or because the guy asked, but because she's really into it." He shifted awkwardly in the chair. "It feels more intimate than just, you know... fucking. Is that weird?"
"No. Not at all." Summer shook her head. "I get it."
Morty glanced back at her.
"I mean, yeah. Obviously." Summer shrugged. "You've literally got a guy's dick between your lips and teeth. You can feel every little twitch, hear all the stupid noises he makes when he's trying not to cum so soon..." She smirked.
Morty stayed quiet, listening.
"Honestly, if it's just a one-night stand, I'd rather blow a guy than fuck him." Summer shrugged. "Less bullshit, less commitment, and I still get to watch him completely lose it."
"You know what I really like?" Summer said, still watching the screen. "Waking a guy up with a blowjob. Assuming he's into that shit, obviously. First thing he sees when he opens his eyes is me between his legs with his cock in my mouth."
Heat had settled between her thighs now, her panties already damp.
Morty swallowed. "That sounds... pretty amazing."
"Ever tried it with Jessica?"
Morty glanced away. "We just kissed last night before she got sucked into that dimension..."
Summer smirked at her obviously virgin brother. "Then you're missing out."
When was the last time she'd actually had a real cock in her mouth? Hemorrhage, probably, back in that post-apocalyptic shithole. What had that been, two months ago?
Fuck. Had it really been that long since she'd sucked a guy until he surrendered in her mouth, felt his cock twitch between her lips, and savored every last drop of seed?
No wonder she was getting so worked up.
The masseuse apparently felt the same way, judging by the relish with which she engulfed her customer's cock. Her full breasts spilled from her open kimono as her head bobbed steadily over his lap. Every few strokes, she pulled back just enough to drag her tongue along his shaft before taking him deep again.
Summer's hands had stopped massaging Morty altogether. She was just gripping his shoulders now, both of them watching their favourite fetish in anticipation.
Neither said a word as the masseuse pressed herself against the man's body, her lips stretched tightly around his long, hard shaft. Wet slurps, licks, and swallows filled the laptop speakers between his increasingly strained moans. She kept her eyes locked on his face the entire time, smiling around his cock whenever she managed to drag another sound out of him.
Summer's eyes kept slipping down to Morty's lap. There was no pretending he wasn't enjoying himself. The thick bulge in his jeans pressed hard against the denim, twitching faintly whenever something on the screen got to him.
Her mouth went dry.
Fuck, she wanted to see it.
She wanted to reach down, pull his zipper open, free his cock from those stupid jeans and feel the weight of it in her hand. Better yet, in her mouth. She could already imagine wrapping her lips around the head, tasting him, taking him deeper inch by inch while he squirmed under her hands and tried not to make those pathetic little Morty noises.
Her lips parted before she even realized she was doing it.
For one second, she could almost feel him there, hot and hard against her tongue, his cock twitching between her lips as she sucked him deeper. She wondered how long he'd last. How much he'd cum. Whether he'd warn her first or just lose control and spill straight into her guts.
Her cunt throbbed with a sudden pulse of horniness, already making her thighs wet.
Summer's grip tightened on his shoulder. Her other hand dropped between her thighs, grinding against herself through her pants. She rubbed her clit slowly at first, just enough to take the edge off while her eyes stayed fixed on the bulge in Morty's jeans.
It only made it worse.
Her panties were already soaked, and every small movement of her fingers drew another wet pulse from her cunt. She bit her lip and rubbed a little harder, still imagining what it would feel like to have his cock filling her mouth instead.
Before long, the guy couldn't hold out anymore. His hips jerked hard off the table as a rough groan tore out of him, but the masseuse didn't let up. She deep-throated him, her lips sealed tight around his cock as he came, swallowing every spurt without pulling away. Her throat gulped visibly as she swallowed his cum.
Summer's tongue tingled with vicarious pleasure. Her whole body smoldered with lust.
The masseuse finally released him from her mouth and beamed proudly at the camera, his semen still dripping from her lips.
The sight left Summer wanting more. She licked her lips, acutely aware that what she wanted was very close by.
Then the clip ended.
Only then did Summer realize she had been holding her breath. She exhaled slowly and broke the silence.
"Wow..." She swallowed. "That was pretty hot, don't you think?"
"Y-yeah..." Morty stammered.
Summer leaned over him and looked down. His cock strained furiously against his pants. A small whimper escaped her before she could stop it, and she swallowed hard.
God, that thing was tempting.
What she wouldn't give to unzip him right there, get his cock into her mouth, feel it throb against her tongue, and feel his whole body shake when he finally came. She wanted to swallow every drop, wanted to know exactly what he tasted like, how he sounded when he lost control, how hard he would grip the chair when she pushed him over the edge.
And she knew he would enjoy it too.
She would make damn sure of that…
"I just love her technique. The way she moves, the way she bobs her head... and she actually looks like she wants to be doing it." Summer smirked. "That's the kind of blowjob I like watching. Like the girl's been poisoned and the only antidote is cum, you know? Passion's the hottest part."
Morty coughed dryly. "Y-yeah. She was... pretty good."
Summer's eyes drifted to a banana sitting on his nightstand, probably stolen from the dining hall that morning.
An idea immediately occurred to her.
A bad one. Which, naturally, made it harder to resist.
"How would you like to see my technique?" she asked. "You can tell me what you think."
Morty turned around so fast his eyes went wide. "What?!"
Summer laughed and grabbed the banana. "Relax. Not for real."
She peeled it as she walked back over, then turned Morty's chair away from the desk and positioned the banana between his legs, letting her fingers "accidentally" brush the inside of his thigh.
He shuddered deliciously.
"Just hold it right here," she said, nudging his hand into place. "And watch."
"I, uh, don't think I should..."
Summer raised an eyebrow. "Why not?"
"Because this is incest!"
"So?" Her smile widened. "This isn't your dimension, Morty. I'm not exactly the Summer you grew up with," she interrupted, a teasing smile creeping onto her face. "I'm way more confident with what I want, and maybe I'm just exploring... life a little differently. You know?"
Morty scratched his head, trying to process her words. "So, like, you're saying it's okay for you to be all... flirty and stuff, but I can't? That seems a bit unfair."
"Not unfair," she corrected, leaning closer. "Just different. You're still my brother, and I'm still your sister. But here, maybe we're just allowed to be a little more... free, you know?"
"I...I guess that's alright..."
Summer licked her lips and smiled. It was a pretty shitty substitute for the real thing, she had to admit, but the look on Morty's face as she tucked her hair back and lowered her mouth over the fruit was real.
That astonished, almost disbelieving look. The way he stared at her like he couldn't quite believe someone was doing this for him. That was what Summer loved most about giving a blowjob. Even more than the control. More than that smug little rush she got when a guy finally emptied his balls in her mouth, and she knew she'd been the one to completely wreck him.
Morty's hand trembled as he tried to keep the banana still. Summer rested one hand on his thigh, her fingers inching almost imperceptibly higher with every bob of her head, closer and closer to the rigid shaft trapped inside his pants. Her fingernails grazed lightly along his inner thigh. With her other hand, she held his, steadying his grip on the banana.
If she closed her eyes, she could almost pretend she had a real, live cock to play with.
Summer took as much of the fruit into her mouth as she could, savoring the full sensation, imagining herself being a good little cumslut with an actual long, thick shaft sliding deep into her throat.
Morty's body trembled. She could feel the dampness between her thighs, her jeans already soaked through.
Fuck. She needed to feel the real thing. Her body craved cock.
Summer had hoped she could fool herself, satiate the hunger with a little play-acting, but it wasn't working. If anything, having Morty sitting there hard beneath her while she pretended to suck him was only making it worse.
It wouldn't hurt to just... touch him, would it?
Just one quick graze.
The pale, soft imitation between her lips suddenly wasn't enough. She wanted a real cock. She wanted to feel the hot meat rod in her palm, wanted to feel it pulse and throb, wanted to feel the powerful shudder running through it when its owner finally lost control and spilled his seed.
Her hand slid the last few inches up Morty's thigh until his erection was directly beneath her palm.
Morty gasped.
Summer sighed deeply through her nose. He was big. Big and hard and firm and hot, even through his pants. Her fingers curled around the thick bulge and squeezed gently.
She opened her eyes and looked up at him.
"Summer..." Morty choked out. "You should move your hand..."
"Like this?" Summer whispered, sliding her hand slowly back and forth along his shaft. That glorious feeling of the real thing filled her hand and her mind. It was perfection...
It was everything she had been trying not to imagine for the past several minutes.
"No, I mean you...shit... Shit, shit, shit...Fuck," he grunted, as his entire body suddenly tensed beneath her. His cock jerked hard against her palm, then spasmed again and again while Morty threw his head back and gritted his teeth, both hands digging into the cushion of the chair as his hips bucked helplessly into her grip.
Summer stopped moving and simply watched, fascinated, as a dark wet patch appeared over the head of his cock and slowly spread through the front of his jeans while he panted through the last few involuntary twitches.
For a second, she could only stare. Then curiosity got the better of her, and she dragged the tip of one finger lightly across the damp spot just to make sure she was seeing what she thought she was seeing. The moisture that clung to her fingertip was warm, sticky, and slightly slippery.
Cum.
"Oh my god, Morty!" Summer blurted, clapping her other hand over her mouth even though it did absolutely nothing to stop the laugh that escaped. "I didn't mean to make you... Jesus, Morty. Wow."
Just watching her blow a banana had been enough to make him blow his load. Fuck, that was flattering. What a shame he'd jizzed in his pants instead of in her mouth. All that wasted cum, unappreciated, untasted, unswallowed...
Summer stuck her fingertip into her mouth and savored his salty flavor, his own personal little treat that had ended up on her finger instead of where she really wanted it. But it was barely a taste, nowhere near enough. She ached for more.
Morty was still looking down at his lap. His face was pink, his eyes squeezed shut, and a single tear slipped from one eye.
"Are you okay?" Summer asked.
"God, this is humiliating," he murmured. "I'm so sorry, Summer. You should go..."
Summer hugged him around the waist. "Morty, it's my fault. I'm sorry. I was the one who... you know. I didn't think you'd go off..." She glanced down at the stain in his pants. "But that was one hell of a hair trigger. Isn't Jessica... taking care of this?"
Morty sighed bitterly. "Not really... Even before the whole time-god thing, we'd only held hands. Whenever things started getting more physical, she'd pull back, so I stopped." He looked away. "And now she doesn't seem interested in any of that stuff at all. I don't know if it's because of everything that happened to her or what, but it's giving me major blue balls."
"I can, uh, see that..." Summer glanced pointedly at the stain in his pants. "Have you ever actually talked to her about any of this? You two sound like a great couple. It'd suck to let something like this ruin things."
"I guess I just don't know how to bring it up, and she is the only girl who doesn't mind Rick and our weird shit. I've spent forever trying to get somewhere with Jessica, and now that I finally did, she went through all that time-god shit. I don't want her thinking I only care about getting laid. She's perfect in every other way. Just not when it comes to my dick... It's driving me crazy. I keep fantasizing about just going down to a massage parlor and getting a happy ending for my sanity's sake."
Summer raised an eyebrow. "So you've basically been giving yourself blue balls over Jessica for months? Morty, that's fucking sad." She gave his waist a small squeeze. "And, hey... I am sorry about this."
"It's fine. Just really fucking embarrassing." Morty looked down at himself again. "Can we please keep it between us?"
"Obviously. And relax, accidents happen. I had a guy come once while he was putting the condom on."
Morty looked up at her. "Seriously?"
"Yeah. We laughed about it, waited until he could get it up again, then I had him lick my asshole anyway." Summer shrugged. "Honestly, I thought it was flattering. Kind of a turn-on knowing I got him that worked up."
"So, uh, what were you thinking about? When did that happen?"
Morty laughed nervously. "Isn't it obvious?"
"Jessica sucking your dick?"
"No."
Summer tilted her head. "That porn chick sucking your dick?"
"N-no..."
Her grin widened.
"Me sucking your dick?"
Morty went completely silent.
That was answer enough.
Summer bit the inside of her cheek, trying not to look too pleased with herself as another terrible idea slipped into her head. She should probably leave it alone. Morty was her little brother, who also happened to be a creep who masturbated all over the house, and right now he was still hopelessly hung up on Jessica.
On the other hand, they were both horny as hell; Morty had just admitted without admitting it that he'd been fantasizing about her, and he was apparently considering paying some random masseuse to do exactly what Summer suddenly couldn't stop thinking about doing herself.
"So, uh...after last night's disaster, how about I give you a special... compensation? Our little secret? No more blue balls for you."
"We can't, Summer. Jessica..."
Summer unzipped his jeans and reached in. The entrancing aroma of arousal and semen poured out. His moist, sticky manhood was still deflated.
"Jessica's not here, and she does not know what she missed. If she's not going to enjoy your cock, she can't complain when someone else does. Besides, you and I are family, right? Just think of it as a sister helping out her brother. This is just a...favor between us," she explained.
"A family-friendly blowjob, plus it's kinky."
Summer pulled him free and studied the soft, vulnerable cock resting in her hand. Even deep in his refractory period, it was still impressive, thick and heavy against her palm, with a soft pink head. He looked delicious.
"I don't think that's a good idea," Morty replied without much conviction.
"Why not? I know you'll enjoy it. It's just like a back rub. But lower down, and with my mouth. If you change your mind, just say so, and I'll stop. What do you say?"
His chest rose and fell as he debated himself. She wished she could hear what he was thinking. Would he say yes? Would he say no? Would he chicken out? His eyes looked scared. She extended her tongue and caressed the head of his cock for a bit of extra encouragement. He shuddered.
"Sure," he gasped.
She blinked. "Really? Fuck it, let's do this."
She took a breath, closed her eyes, parted her lips, and engulfed his cock, gently suckling the soft organ. It was hard to believe something so limp and vulnerable could grow into the thick, massive cock that had been threatening to burst out of his pants only minutes ago.
It didn't take long for her efforts to have the desired effect. His penis slowly began swelling inside her mouth, stirring back to life despite his refractory period, and Summer silently thanked evolution for such a delightful design. The feeling of him growing between her lips was incredible.
She wanted him rock hard again. She wanted him writhing beneath her mouth, wanted to feel him throb against her tongue and finally cum inside her. She craved it, the anticipation already building into an avalanche of pleasure waiting to be released from her pussy.
Summer kept sucking as one hand wandered over his thigh, her fingernails grazing lightly along the sensitive skin before her fingers brushed against his balls. They tightened instinctively at her touch while his cock gave another heavy throb inside her mouth. She waited for Morty to tell her to stop, to say she was taking things too far, but he never did.
She looked up at him instead and found his eyes fixed on her, confused and overwhelmed. Was he surprised that his sister was actually doing this for him? Glad that she was? Ashamed that he was letting her? Terrified that their parents or Rick would somehow find out? Summer couldn't tell, and right then she didn't particularly care. She had his cock in her mouth. That was enough.
By now he was fully hard again, his smooth, firm shaft filling her mouth perfectly, and Summer luxuriated in the sensation of having him there, as though her lips and tongue existed solely to pleasure him, to work him toward another orgasm and swallow every bit of the salty cream when he finally lost control.
She drew a careful breath through her nose and slowly worked her way farther down his length, taking him deeper and deeper until her lips brushed against his pubic hair and the head of his cock pressed against the back of her throat.
She savored the sensation for a few seconds, a sheath for his sword, a hole for his cock to rest in, while his body trembled above her.
For one stupidly aroused moment, Summer wished she could stay kneeling there all day, keeping his cock between her lips and sucking him off every time he grew hard again, his own personal little fellatrix slave. Nothing got her going quite like giving head, worshipping a man's cock, pleasuring him, and stimulating his most private and intimate organ.
She eased back just enough to breathe, the head of his cock sliding past her lips before she swallowed him down again. His shaft dragged over her tongue, his scent filling her nose as his cock pulsed and throbbed inside her mouth, every beat of his heart transmitted directly against her lips and tongue.
Morty gave a strained grunt. "Oh, jeez... I'm gonna cum."
Summer immediately wrapped her arms around his waist and pulled him deeper into her mouth, unwilling to waste a single drop this time as she eagerly waited for him to climax.
She didn't have to wait long.
His cock spasmed inside Summer's mouth, and the sensation finally pushed her over the edge. She quivered between his thighs as cum gushed over her tongue, nearly overwhelming her, her own orgasm ripping through her at the same time. Pleasure spread through her limbs until her head went hazy and she lost track of everything except the cock pulsing in her mouth.
Morty put a hand on the back of her head and held her there as he spurted more cum into her, encouraging her to swallow, not that she needed any encouragement. Summer eagerly swallowed down every last drop of scrumptious semen, gulping again and again as each mouthful slid down into her tummy.
She kept sucking until there was nothing left to coax out of him. By the time Summer's own shuddering finally subsided, both of them were breathing hard. She reluctantly let his softening cock slip from her mouth and sat back between his thighs while Morty sagged against the chair, jaw hanging open in exhausted satisfaction.
Somewhere in the back of Summer's mind, her conscience pointed out that sucking off her brother had probably been a huge fucking mistake. Unfortunately, her libido was still celebrating far too loudly for her to care much.
"So..." Summer licked the last traces of cum from her lips. "What did you think of my technique?"
"Amazing..." Morty mumbled dreamily. "Incredible. I really needed that."
"I'll say. I was worried I was gonna drown for a second." Summer smirked. "That would've been one hell of an embarrassing obituary."
Morty gave a tired laugh. "Glad you didn't choke. I, uh... probably wouldn't kiss you right now, though. No offense."
"None taken. It's an acquired taste." Summer ran her tongue over her lips once more. "Delicious, though."
Morty smiled despite himself. "So, uh, Summer... would you mind if we made this a regular... thing?"
Summer raised an eyebrow. "Morty, are you asking me to come to your room and suck your cock whenever you need to cum?"
"Well..."
"Gladly." She had to admit that agreeing to blow her little brother on demand made her feel a little like a cum slut. Okay, a lot like one. Even so, the thought only warmed her all over again and made her want to go back to her room, lock the door, and drain the batteries of her vibrator.
Besides, it couldn't hurt, right? It was nothing more than a blowjob.
