Ahhhhhh!" Levi shuddered as he fired his first cumshot of the day into his sister's loving mouth.
Aubrey swallowed his load and then swirled her tongue over his shaft to clean it up. They were in a hurry, already a few minutes behind schedule. They had to leave fast if they wanted to have any chance of making it to Levi's school on time.
"Okay, you got your blowjob. Now pull your pants up and get moving!" Aubrey clapped along with her command. This wasn't their normal morning routine, far from it. They had agreed to keep mornings as normal as possible for a smooth transition to school or college. But occasionally things slipped up.
"T- thanks." Levi dreamily followed his sister's orders. He'd been so backed up and ready to pop that he begged for a quick blowjob. Aubrey normally chided him for being so needy but today was an exception. They'd gotten home very late last night from a school function, some new club member orientation that Levi had to attend. Exhausted, the siblings hadn't indulged in their normal fun.
"Yeah, yeah. Just go finish getting ready." Aubrey could still taste her little brother's spunk on her tongue. She considered washing it out, that wouldn't take too much time. But it could also be a fun little hidden reminder of her lover. She licked her lips and moved to pack up her bag.
The duo was fully packed up for the day and ready to head out the door in just a few minutes. Levi's uniform pants were still fairly fresh and didn't show signs of what had transpired. Aubrey's knees were a bit red but that would wear off quickly. They had to go, now!
Driving through the city in morning traffic was annoying but something that Aubrey had come to accept as normal. Just like most of their morning routine. She thought back to what she and her brother had done a few minutes ago. The delicate perversion they took part in. Most of their days were finally falling into a regular schedule now, easy to predict and manage. That little bump had been fun and if they were late, well that wasn't all too big of an issue.
**********
Aubrey let out a long sigh but her breath caught at the end of it. Levi had finished up his little treat and was now eagerly sucking at her nipple. She maneuvered the can of whipped cream around to cover her other breast with some of the light, sweet delicacy. Levi quickly switched his attention across her chest and began lapping away at the new topping of cream. The siblings were both completely naked in Levi's room.
This rather interesting idea had come from an online guide on 'how to spice up your sex life'. Aubrey had been skeptical of it at first but was now thoroughly enjoying her little brother's eager ministrations. They'd been at it for about 10 minutes now and had gone over almost every inch of Aubrey's body. Thighs, stomach, arms, breasts, neck, ass, crotch. The can of whipped cream was getting a bit empty.
Running a hand through his hair, Aubrey pulled Leiv's face to her own and kissed him. "Okay, my turn to eat you up."
Swapping positions, Levi happily laid back with his stiff member jutting upward. Aubrey wanted to give him the same treatment, small dollops of cream all over with long, passionate licks to clean it up. She adored his body, so small and cute.
About halfway through that process, she noticed Levi had discretely stated jacking off. She smirked and put the last bit of whipped cream onto his cock head, slurping the sweet treat into her mouth. That quickly escalated into two rounds of incestuous sex, both punctuated with a deep creampie.
Sweaty, sticky, and exhausted, the lovers cuddled up. Aubrey could feel her brother's loads oozing deep inside her as he nuzzled up to her, looking so adorable. Maybe they could try the chocolate syrup next time.
**********
"Aubrey! Look!" Levi bounded up to his sister's car after school with a paper in his hand. It was a test with a sharp 94% written at the top in red pen. "That brings me back up to an A in science!"
"Nice job, dude! I knew you could do it!" Aubrey gave her brother a side hug as he settled into his seat.
"So that means I can get my reward tonight, right?"
"Only ever one thing on your mind, huh?" She teased him as they pulled away from the school.
Later that night, Levi sat on his bed in just a pair of underwear. His cock was already hard and eager. The anticipation was killing him. Aubrey was in her own room, digging through some clothing storage to find a particular garment.
Finally, a light knock came at the boy's door and Aubrey let herself in. She was wearing a deep purple bikini, a skimpy little two-piece swimsuit that she'd gotten a while back. She'd worn it a few times to the beach or around pools, but to her knowledge Levi had only ever seen her in it once. Which was why she was surprised that he requested it as part of his reward.
Levi still vividly remembered the one summer afternoon he'd gotten a good eyeful of his big sister in that bikini. It was one of his fondest memories of her body from before they got together. And now he was finally going to get to do what he'd imagined doing all that time ago.
"How do you want me?" Aubrey sauntered over to the bed and leaned down to look her little brother in the eyes. Her pose also greatly accentuated her cleavage.
Levi made no attempt to hide where his eyes were looking. "On your back. Prop yourself up with some pillows."
The siblings positioned themselves with Aubrey reclining back and Levi mounting her abdomen. His underwear had long been discarded and his throbbing cock poked at her breasts. Grabbing the now very close to empty bottle of lube, Levi generously coated his member and then squirted a bit into Aubrey's cleavage. Pulling up on her bikini top a little, he could just manage to slide his rock-hard erection between her pillowy tits.
It took some working and repositioning, but soon Levi was dreamily thrusting between his big sister's lube covered breasts. Aubrey laid back and used her hands to press her tits together, mashing the slippery flesh even tighter around her brother's stiff rod. She wasn't getting a lot out of this… but he certainly seemed to be having fun.
Levi panted along with each frantic thrust of his hips. His hands gripped the headboard of the bed. He was getting too worked up but he couldn't help himself. The fantasy was finally real and he knew this would be a big load. His eyes were locked to where his cock was enveloped into Aubrey's bosom. The sight of his rod disappearing into her welcoming canal while framed by that tiny bikini was intoxicating.
Knowing he was on edge, Aubrey tried to push him along. "Gonna cum big boy? Gonna blow a nice big load all over your big sister's chest?"
Levi cried out and gave one last hard shove before his cock erupted with one of his biggest loads of cum ever. The first few shots blasted through Aubrey's cleavage and hit her neck and chest. She squealed in surprise but kept massaging her tits around his pulsing member. Levi pumped another shot directly between those tits before pulling out and spraying his last few ropes over the bikini top. He jacked his spent cock until every drop of cum had leaked out. He stared at his hard work, a masterpiece of boy cum, delicate fabric and bountiful tit flesh.
"I love you." The boy happily mused as he slid off his sister's body.
"Love you too buddy." Aubrey wasn't the biggest fan of having cum all over her body, but she took the load like a champ if it meant Levi did his best in school. This was the first time she had used a sexual reward for such a purpose. It seemed to have worked fairly well. Maybe the promise of giving her a facial would incentivize him to do well on semester exams.
**********
"Hey, did you think about what I said the other day?" Aubrey posed the question to Levi. The lovers were cuddled up on their small couch, both wearing comfortable sleepwear. They had fucked just an hour earlier, before dinner. While they were bound to get worked up again eventually, for now the siblings just enjoyed the other's embrace while they watched a show on Aubrey's laptop.
"Yeah. It seems… interesting, I guess. Could be lots of fun."
The topic of discussion was that Polaris_34 had mentioned that he and his sister would be traveling to Aubrey and Levi's city next month. Neither party had ever mentioned where they lived, so the event was purely coincidental. The couples had, however, discussed the desire to see each other in action. Trading pictures or videos seemed far too dangerous so not much ever came of it.
Aubrey had voice chatted with both Polaris and his sister, Levi having joined in for a little while too. She was fairly convinced they were the real deal and felt comfortable enough to propose a meet-up, but only if her brother was totally willing as well. The specific details of what they would be doing were still something that needed to be discussed fully.
"It's really a tough spot. I would like to meet them but at the same time it is a bit of a risk." Aubrey pondered out loud.
"I think they're cool. And it might be the only time we get to do anything like this. At least talking about it with them would be good." Levi nuzzled against his sister's shoulder.
"Okay. I'll see what I can set up." Aubrey rubbed her brother's hair and they continued their show.
**********
"Mhmm!! Slower." Aubrey growled at her little brother. She tightly gripped the sheets of her bed while he knelt behind her upturned ass. His very well lubricated dick was buried halfway into her anus.
This wasn't the first time she had done anal but it was the first time in a while. Maybe a bit more practice with a properly sized toy should have been done. Aubrey regretted her lack of preparation for this one.
"This was your idea." Levi held still while his sister adjusted to his invading member. His small hands were gently gripping her hips and caressing her skin.
"Yeah, cause' I know it feels good once I get used to it." She let out a long breath and relaxed. "Okay, push some more."
After a few more slow inches, Levi was finally rooted all the way inside his big sister's tight ass. It was an oddly different yet familiar sensation from what he was used to. Keeping himself from thrusting was a bit of a challenge. The siblings were locked together, connected in their forbidden union and unable to move for a bit.
"Can I…?" Levi prompted.
"Very small strokes. Slowly." Aubrey was starting to get the feel of this again. She thought she knew exactly how big her little brothers dick was, but it felt so much bigger right now.
Levi gingerly rocked his hips just the slightest bit. This elicited a moan from Aubrey whose face was pressed into the bed. Still a bit unsure, the young boy started to repeat that motion. Soon he was pumping at a very moderate pace, leaving plenty of time for his sister to voice any concerns.
"Okay. Faster." Muscles finally relaxed; Aubrey was really starting to enjoy the filling sensations of her brother's cock. It was a very nice size, hit all the right spots. She moaned in pure pleasure, ready for some rougher treatment.
Levi, though, was scared of going too fast. He sped up his hips just a tiny bit and pulled back for a longer stroke. The new experience was nice, the sensations were fun and driving him to stay rock hard. But he kept himself from pumping as hard as he could for several strokes.
"Hey. I'm loosened up now. You can go as hard as you want." Aubrey glanced back at her little brother, balls deep in her ass and quivering. She moved a hand to rub her needy, wet pussy and play with her aching clit.
"O...okay. Just let me know if you wanna stop." Levi focused to let go of his restraint and pulled back, letting his full force slam back into the tight hole he was fucking.
"Oh god fucking shit." Aubrey cursed. "Keep going! Don't you dare stop!"
Levi happily complied, pistoning in and out of her clenching asshole with wild youthful energy. Soon he was ramming her butt with all of his boyish strength, their skin colliding in rhythmic slaps. This felt great for him, maybe even more fun than a normal fuck. Aubrey continued to vigorously rub and finger her empty cunt, needing to feel even more full. She let out a long, low moan as her brother kept up his assault.
"Pull my hair and slap my ass." Aubrey was really getting into a mood now.
Never having done anything so remotely domineering, Levi hesitated for a moment but then complied with his sister's command. He reached forward to bunch up her flowing hair and held the reigns tightly in his left hand. On a particularly powerful stroke he paused to line up a hard smack against Aubrey's round, pert ass. Levi had never felt so powerful, so primal and in control. The young boy was newly intoxicated on this fresh high of dominance. Another well placed hit landed on Aubrey's other cheek a moment later.
Aubrey was happy to let her little brother feel in control if it meant she got fucked like a proper whore. Her back arched low from the relentless pounding of her ass and firm pull on her hair. She smirked as she heard Levi grunt in time with his thrusts. The smaller boy repositioned his feet and got a better angle for his wild frenzy of a pounding.
The animalistic fuck session went on and on, the siblings enraptured in their own carnal desires. Levi treated his sister like a living toy, boy-handling her body to his own whims while she took his assault and made it into her own pleasure.
Not even bothering to warn her, Levi slammed his body onto her own as he reached the peak of orgasm. His cock twitched and swelled as it shot copious amounts of thick seed into her rectum. Aubrey's eyes rolled back in her head as her little brother came in her ass. Her own fingers were flashing in and out of her cunt, taking her to an inevitable conclusion.
Both siblings cried out in ecstasy from their joint pleasures. Aubrey collapsed forward onto the bed and Levi fell atop her. Panting hard and fast, they took a few minutes to recover. Levi was the first to pull away and slip his softening cock from its sheath. He collapsed next to his big sister on the bed. Both of them knew anal would be added to their list of favorite activities.
**********
"AUBREY!" Levi clenched his fists around a bed sheet.
"Sorry, sorry! This is new for me too."
The duo was in a very similar position to their first anal adventure, but this time the roles were a bit different. Very soon after their introduction to anal sex, Levi had sheepishly expressed interest in finding out what that felt like on the receiving end. Aubrey encouraged the idea and introduced him to what a strapon was. He was instantly smitten with the concept, begging his sister to get one.
They'd started with a training set of butt plugs, slowly getting him used to relaxing his muscles. That had taken a few weeks of slow practice to get down. Aubrey had found some perverse pleasure in riding the small boy whenever he was plugged.
This time was their first test of the strapon. Aubrey had specifically purchased a modular one that could accommodate a variety of phalluses. The one half-way inside her brother at the moment was only about three inches long and quite thin. She knew he needed to start small, even after all the loosening up. There was a larger toy waiting in her closet for the right time.
Levi took a deep breath, steadying himself. He knew well enough to not tense his muscles but it was a struggle not to. He did greatly enjoy his sisters loving hands caressing over his ass and hips. His stiff cock hung between his legs, unused but ready to go.
"Play with yourself a little. That'll help." Aubrey focused on gently sliding her newfound manhood slowly and steadily. She was actually finding it quite liberating, being the one in control of such a tool. Her hip movements were not quite as natural and instinctual as her brother's but she was getting the hang of it.
Levi moved a hand underneath himself and began slowly jerking his cock. This was all so new and strange but he trusted his big sister to be gentle. She'd trusted him in the same way after all.
Just another inch into his ass, the plastic cock hit a sweet spot. Levi had never felt such an intense orgasm build up in mere seconds. He cried out as his hand went wild on his cock. In just a few moments he was already going to cum.
Aubrey had known male prostate orgasms could be powerful but she hadn't been sure if her brother would react strongly. Seems like he did. She barely had time to process what was happening before he tensed up and began shooting his cum into the bedsheets beneath him. Aubrey cooed over his orgasmic form and gently scratched his back. She wanted to give another thrust but knew it was probably best to let him ride it out. Overstimulation could be for another day.
"Good boy~. Looks like we found your happy button, huh?" She giggled as she watched her brother splayed out on the bed with the strapon still inside him.
After recovering and cleaning up, Levi lavished his big sister with the best cunnilingus he could muster. She took her time with it and made him bring her to the edge several times before finishing. Such a good, obedient boy. The siblings went to sleep that night with a newfound sense of adventure. Minds swirling with new pleasures to discover.
**********
"I need you to be serious for a bit." Aubrey stared into her brother's eyes.
"Okay. What about?" Levi fidgeted in his seat. The two were sitting at the dining table, something they rarely ever did unless it was for a meal.
"I have… a new thing I'd like for us to try. But it's more… personal? Serious? Basically, you're going to have to be very mature about it. You've heard of roleplay, yes?"
"Oh, yeah. Like pretending to do things." Levi relaxed a bit.
"Yes, like that. There's a scenario I would like for us to try out and maybe mix into some other things." Aubrey was the one getting nervous now. She had always been thinking about it, ever since that very first time Levi had shot his seed inside her. She'd never quite trusted herself to broach the subject until now. Levi was mature enough to handle it and it would be perfect for heightening their sexual pleasures.
"Umm, well. So. You have to realize that this is all fantasy, okay? All for fun and no matter what we say in the moment, it's just for that moment. Alright?"
"Yeah, sounds good."
Aubrey took a deep breath. "You know I'm on birth control. We've been over that. There's no chance of you getting me… pregnant." She paused. "But… I think… it would be very fun to pretend that you could. It's sort of a kink I've had for a long time. It doesn't have to be a lot, or not at all if you don't want too."
Levi cocked his head. "So, like, just talking about it while we fuck? Pretending like it could happen?"
"Yes! Yes, just simple stuff. It doesn't have to be too intense."
A few minutes later Aubrey was on her back in her own bed, legs folded up to her sides. Levi's small body was enough to hold her in that mating press as his diamond hard cock ravaged her soaking wet cunt. Loud moans and grunts came from both siblings as their skin clapped together in powerful shockwaves.
"Fuck a baby into me! God fuck! Knock me up with your little boy cum!" Aubrey squealed as she took the rough pounding her brother was dishing out.
"I wanna knock you up so bad! Breed my big sister nice and full." Levi was having fun playing along. He wasn't completely sold on the breeding kink yet but it sure made Aubrey go wild. And that made the sex feel fantastic.
The siblings locked lips, hungrily devouring the others essence while they continued to pound away. Aubrey dug her nails along Levi's back, marking her territory. This little stud of a boy, her own brother, was going to impregnate her with his potent spunk. The thought catapulted her need to new heights.
"Give it to me. I need it, fuck I need it so bad. Blow your load deep in my fertile little pussy." She mewled into Levi's ear as he powered his hips up and down. Finally ready to blow, the young boy focused his willpower to deposit a huge load straight into his sister.
"Get! Fucking! Pregnant!" Each word accompanied a powerful thrust until Levi was balls deep inside Aubrey and his cock erupted with jets of cum. Both of them howled with utter ecstasy, arms wrapped around each other and bodies grinding for even more contact.
The cooldown took longer than their normal sessions. Levi felt his spunk oozing around inside his sister and secretly hoped that it really did work. That would be really cool. Aubrey slid her legs into a more comfortable position and kissed her brother's head. "That was the best. Like… wow. I can't… even… wow."
"Yeah. Me too." Levi kissed her breast and propped himself up on his arms. "I could definitely go for breeding you more."
Aubrey shuddered at her brother's words. "Roleplaying. Roleplaying breeding. That was amazing, but it was just for fun."
"Mhm." Levi extracted himself from his sister's messy cunt. Rolling onto the bed beside her, he looked lovingly into her eyes.
"Agh, you are way too cute." Aubrey rolled onto her side to gaze back at him.
The siblings spent the rest of the day 'roleplaying'. Levi completely emptied his balls from the continuous stream of orgasms. He tapped out after their fifth round, something the young boy rarely ever did. Aubrey felt like she had taken gallons of cum right into her womb. This was definitely the ultimate test of her birth control. She was completely exhausted but beyond satisfied.
The duo had opened up so many doors for future exploration. Their relationship was at a new level. It was the happiest either of them had ever been.
