Chapter Text
Many soft, warm sensations filled Aubrey's mind as she became conscious. The quiet atmosphere of a lovely Saturday morning was soaked into the very air around her. No schedule to keep, no alarms insisting she wake up, no rush to get them out the door. Yet she was still awake early, her internal clock ticking right on time. What were her priorities today? She had a paper to work on later, not anything pressing. And a trip for groceries had to happen as they were running low on some necessities. Other than that…
The twenty-year-old college sophomore stretched out in all directions, the soft covers of her bed yielding to her movements. Her right hand encountered a familiar obstacle, something very warm and welcoming. His shirt was loose, easy to grab a handful of if the need arose.
She slowly twisted onto her side and found her bedmate still sound asleep. Since it had started, he'd spent more nights in her bed than his own. It was comforting to know that he still wanted to be near her after most of their long days. He used to be a little standoffish about spending too much time together. But now things were a bit different.
Aubrey gently moved in closer, sliding her body along the bed just enough to reach out and place a hand along her companion's stomach. He was breathing softly and steadily, face absolutely placid in his slumber. So cute. He was still deeply asleep, recuperating the excessive amounts of energy they'd expended last night. Fridays were their fun night when they knew the next day would be an easy one.
Aubrey closed her eyes and flittered back into a semi-conscious doze. Some amount of time passed but it could have been minutes or days from her perspective. New sensations jostled her back to reality, a lively rustling of the sheets and hands gently grabbing at her body.
Levi was quick to search for his bedmate once he woke. A long snuggle to start the day was never a bad thing. He pressed his smaller body to hers and yawned. The pair were not at all ready to get out of bed and could easily spend more time relaxing. Though Aubrey had a suspicion of what would come next.
Levi usually woke with a very specific need. Something the pair had gotten very used to in their time together. Most mornings, it had to be dismissed in favor of getting them ready and out the door. But today it was nice to lay back and let things play out.
Right on cue, Aubrey felt Levi's member stretch his shorts and rub against her abdomen. Cutely, he nuzzled into her more and slowly began rocking his hips. Smiling, Aubrey kissed his forehead. "Ah, you're raring to go… so early too… can't a girl get some rest around here?"
"But… but you said we could on the weekends?" Levi was bemused. Still not fully awake enough to catch Aubrey's playful tone.
"Oh, alright. Keep going like that, let's work up to it." Aubrey wrapped her arms around the smaller boy and pulled him into herself. The pair shifted around to find their ideal position while Levi kept gyrating his hips.
They were both remarkably worked up in short order, hands roaming freely under clothing to find all those lovely sensitive spots. Aubrey clenched her thighs and cooed over the rutting boy. Levi, for his part, was getting lost in the supple body of his older lover. He kept grinding his erection into her crotch and pressing his face into her soft chest.
"Mmmm, Aubrey… can we now? It's… I gotta… y-yeah." Levi babbled as his body clearly conveyed his need.
Aubrey twisted onto her back and lifted her legs into the air. She slowly peeled her shorts and panties up and off in one smooth motion. The garments quickly went flying off to the side. Levi watched, transfixed, even though he'd seen the spectacle many times before. Spreading her legs wide, Aubrey shot her best 'bedroom eyes' at the boy. "Come here and fill me up you little stud."
Levi hastily discarded his own shorts and scrambled to get on top of the girl. Lining himself up with her wet and welcoming hole was still a bit of a challenge but he'd gotten much better at it after quite a bit of practice. With some effort he managed to point the tip right to her entrance and slowly push forward. Aubrey gasped and grabbed at Levi's shirt as the cute boy penetrated her for the first time today.
"Holy fuck, you're so hard. Give it to me baby, give it to me fast and rough!" Aubrey pleaded with her young lover. Levi's only response was a long, high-pitched moan as he tensed his legs and began to thrust his hips. When they'd started out, his technique had been wild and unrefined. But now the young boy could keep a consistent, earth-shattering rhythm that sent his older lover to the moon. Aubrey was delightfully proud of his improvement.
The pair melded together on the bed, clinging to each other for dear life. All four hands were gripping some fabric or bit of soft skin. Levi favored the loosely covered breasts of his lover, grabbing and kneading them with fervor. Aubrey had become lost in the joys of their carnal pleasure, throwing her head back to shout as Levi continued to piston his member into her depths. The boy was all too far gone now for any words to reach him.
Holding his head between her ample breasts, Aubrey felt the moment when Levi passed his limit. His steady breaths turned into shaky panting, and she knew what would come next. Wanting him as deep as possible, the girl quickly wrapped her legs around the wiry frame of her young stud and held him in place. Not that Levi needed any extra motivation to bottom out inside her while his cock erupted its thick, hot load.
"FUCK YES, I love my little step-brother's cum!" Aubrey's voice quivered in a falsetto as she dug her nails into Levi's back, urging him to keep going. She needed to feel that forbidden baby batter squirm its way into her inner most sanctum. Thinking about what it could do there... Her body couldn't get enough. More and more and more and more…
Levi shuddered and pumped his last spurt into his big step-sister. The eleven-year-old boy was now thoroughly spent, at least for a few hours. Aubrey, on the other hand, had gotten close to her own orgasm but it had been just milliseconds away when Levi finished his own. Desperate, she moved a hand in between their bodies to rub at her clit.
Levi shook off his orgasmic stupor and squirmed. "S… sorry that was quick. I can definitely help you cum. If you want."
'Oh no, he's too cute.' Aubrey thought. She rubbed his cheek as he stared up at her with an embarrassed but still aroused look. In their time together, she had definitely come to understand that Levi was a sucker for making sure his partner was happy and satisfied. And she… well she wasn't going to let the opportunity go to waste. "That's totally okay. You were maybe a little overexcited. Why don't you put that tongue to good use, yeah?"
The step-siblings both greatly enjoyed the act of cunnilingus. Aubrey for obvious reasons and Levi because he got to have the satisfaction of giving his big step-sister a powerful orgasm. As he slid down her body, Levi took the time to kiss and lick every bit of skin he could. Everything from her stomach down to her inner thighs. He maneuvered into a position to eat her out and settled into the act.
Aubrey was still surprised that her step-brother was totally fine with eating out a pussy that he'd just creampied. She hadn't really brought up the oddity of it to him, mainly out of fear that he would get self-conscious and stop. She had never met another guy who would do that, much less one who was a great lay with untold stamina and super adorable to boot.
Levi did, in fact, put his tongue to very good use. Though he was coming down from his sexual high, the boy put his all into eating out his big step-sister's well fucked pussy. This was one particular skill he excelled at, even since their first time together. Careful study and practice had honed his mouth and tongue into formidable sexual weapons that Aubrey could barely resist.
"Hohhoooo~! Just like that!" Aubrey got a death grip on Levi's hair and held him in place. It wouldn't be long until she was back at the peak of orgasm, might as well enjoy the view. She propped her head up with a pillow and lustfully gazed at the cute boy between her legs. Levi's eyes twinkled with affection and submission as he curled his tongue inside her. His arms were wrapped around the underside of her thighs to pull himself in.
Aubrey panted and heaved as she was eaten out, body twisting with pleasure. One of her hands moved to play with her breasts through her loose shirt. She tenderly rubbed around her hard nipples and pulled her shirt to accentuate the stiff buds. She knew Levi loved the look of her nipples through a thin shirt and she was more than happy to accommodate. The way he stared at her was intoxicating.
"Oh fuck, I'm gonna cum, keep going, keep going, keep going!" The final climax that both step-siblings had been working toward came with a prolonged cry from Aubrey. Her whole body shook as her face and chest blushed red. She used one hand to forcefully press her step-brother's head into her crotch while the other pinched her nipple. Levi rode through the climax by gently sucking at his step-sister's clit just like she'd taught him to do. She got off much harder with that specific stimulation.
Now both properly satisfied, the step-siblings readjusted on the bed to cuddle a bit more. The bed was now very warm, heated by their carnal lovemaking. Aubrey was happy to feel her step-brother's soft cock against her leg, this way she could easily tell if he got hard again for round two. The reality was, unfortunately, that both of them were out of it for the time being. They dozed for just a bit, lost in the post orgasmic glow of the morning.
Aubrey finally blinked hard and rubbed her eyes. "Alright, buddy. Time to get up for real. We've got stuff to do."
Levi made one last, big stretch and rolled to the edge of the bed. "Can we have pancakes for breakfast?"
"If you go get all the stuff ready in the kitchen. You know where it all is?" Aubrey was using some wipes from the bedside table to clean herself up. Creampie sex was fun, but not exactly convenient. They had little stashes of wipes all around the house.
"Yeah, I got it!" Levi hurriedly found his shorts and pulled them on before rushing out of the bedroom.
"Hey! Don't forget to clean yourself up!"
"Oh! Right. I'll do it."
Aubrey had firmly switched back into 'big step-sister mode'. Though, reminding her little step-brother to clean up after sex was not what she would have ever expected to use it for. Normally she would get him to do his homework or chores or read more books. He would definitely do what she told him to though, he was a good kid. She chuckled as she went to fetch her shorts and thought about how they had ended up like this.
It had started four months ago when Levi had been accepted into a prestigious private school. He had always had a talent for academics. The school was several hours away from their family home and neither of their parents had the ability to relocate quickly. It was, however, just across the city from the college Aubrey was attending. After a lot of back and forth, their parents had agreed to let the step-siblings live together in a comfortable 2-bedroom apartment. Aubrey was relieved to get out of the dorms and Levi was happy to go to his new school. The two of them had always had a pretty good relationship, only occasionally squabbling over silly things, so it seemed like a good fit. Aubrey had promised to be the mature figure in the house and make sure her step-brother was taken care of, even if that meant not getting to do all of the traditional fun college things. Having boys over to the house was strictly forbidden as a baseline rule. But it turned out that wasn't really a problem.
For Aubrey's part, she had always known she was a bit of a shotacon. Guys her age were nice, she'd already fucked a few of them. But young, cute, innocent boys really got her engine purring. She'd always relegated those desires to hentai and stories, fictional outlets where there was never any real risk. She had fantasized about her step-brother in the deepest and darkest moments of her depravity, but it hadn't been more than a passing thought in her lust-crazed mind.
Levi had only just started to explore his own sexual tastes but had quickly discovered his big step-sister's body made him feel things. He would steal long glances as often as possible and give her tight hugs. He even went so far as to steal a pair of panties from her room while she was at college. He still wasn't sure if she knew about that. He hadn't really meant anything serious by it, it was really just so he could jack off with them. Though the fantasy had taken root in his mind.
When each of them learned that they would be living alone together, many wild thoughts ran through their heads. A flurry of crazy hedonistic fantasies that only lasted a second. They were both too strait-laced to let it go much further.
That fell apart just a few days into the co-habitation when Aubrey accidentally walked in on Levi masturbating. She quickly slammed the door shut and loudly apologized, the image already permanently burned into her eyeballs. That incident led to more and more openness between the two, less boundaries on what happened in the house and when. Aubrey was maybe unconsciously being careless when Levi caught her in the same compromising position a few days later. Now that they were even, it became a much more common occurrence. One particular night, they achieved simultaneous screaming orgasms from adjoining rooms.
All of this came to a head one night when Levi asked to sleep with Aubry because he was lonely. She'd taken him into her bed, embraced him and helped him feel loved. What started out as step-sibling bonding ended with multiple incestuous creampies and a drastic shift in the nature of their relationship.
Aubrey had immediately felt incredibly guilty about her inability to keep her own desires in check. Levi was a bit too young to really understand why their union was forbidden, he was just a horny kid acting on his instincts. She should have been the one to stop it, but she couldn't bring herself to do it. Especially after that first time when her body reacted so powerfully to his young vitality and spirit. His dick was pretty enticing as well. She knew what the consequences of her actions would be and made very sure Levi knew as well, but ultimately couldn't give up the simple love she'd found with her little step-brother.
Getting out the last of the materials for their pancake breakfast, Levi arranged the ingredients on the counter and put the pan on the stove. He wasn't allowed to cook anything on his own yet, Aubrey had said she would teach him how to use the stove at some point, but their time together was usually a little occupied with over activities.
"Everything's ready!" He chirped when Aubrey walked into the small kitchen/dining area.
"Alright, let's get to work." The duo (mainly Aubrey) spent the next few minutes cooking their food. Two fairly large pancakes, extra fluffy, along with some strips of bacon that were always an annoyance to fry.
They sat down to eat and enjoy the slow morning. Most days they had to rush out to school and classes so only the weekends were calm. Levi hummed at his syrup covered delight and swung his feet under the table. Aubrey checked her phone while they ate, scrolling through some emails and social media until she thought to check on that particular forum.
After some very discrete searching, Aubrey had found an online forum for people who partake in all forms of incest. Most of the members seemed to be fairly genuine, though it really was impossible to tell. At least everyone was helpful and sympathetic to the situation the step-siblings found themselves in. A couple of people seemed to have almost the same relationship status, an older step-sibling keeping watch over a younger one. One particular person had really helped Aubrey out with advice at the beginning, they had been talking for a while now.
"Reading the forum again?" Levi kicked his foot against Aubrey's.
"Oh, yeah. How'd you know?"
"You get this really serious look on your face."
"Wow I'm that easy to read, huh? You done eating?"
"Yup. It was really good, thank you!"
"Alright then, why don't you put our plates in the sink to soak and then go get dressed to go shopping." Aubrey watched as her little step-brother scooted around the small kitchen, his lithe frame and toned muscles were great to just admire. Not for the first time she wondered how she'd gotten so lucky.
Levi liked it when his step-sister watched him. She thought he didn't notice but he definitely did. It felt good to be admired. Finally putting up all of the dishes, the young boy bounced over to give his big step-sister a hug. She readily opened her arms and embraced him. With her sitting down, their lips met at just about the perfect height. The step-siblings shared a passionate kiss, bodies pressed together and tongues lashing around in a slippery dance. Their hands wandered, Levi's smaller digits digging into Aubrey's sides while her own pulled his hips closer. The two were nearly lost in the moment of forbidden lust.
"Mhmm~ enough of that." Aubrey pulled away and pressed a hand to Levi's chest. "We've got things to go do. We can have more fun when we get back."
Levi groaned in complaint. He was just starting to get hard again. His stamina was very impressive, he could not only get it up multiple times a day, every day, but also kept pumping out thick, sizeable loads with every round. Such were the wonders of youth. It was a herculean task for Aubrey to get them separated once they got riled up so she knew to stop things before they got too heated.
"No buts mister. We get chores done, then we fuck. Come on, get moving." Aubrey was adamant to not waste the day away despite how damp her panties had gotten from just that little bit of love. Today would certainly be fun, and maybe a bit of innocent teasing while they were out could keep the mood going. Aubrey grinned as she watched her step-brother scamper away to get dressed in his room. Just as eager to eventually continue their fun, she moved back to her own room to do the same. The promise of a long, uninterrupted sex session could motivate both of them surprisingly well.
------x------
The small, grey car idled at a stoplight. Traffic was, thankfully, almost nonexistent today. The city streets were usually annoying to navigate but the drive on Saturday morning was much easier. Aubrey tapped the steering wheel and hummed along to the song on the radio. Levi was occupied on his phone, playing a fantasy strategy game. The duo had quickly gotten dressed after breakfast and were on their way to the supermarket. They had both calmed down since their shared kiss, now very much in the proper step-sibling headspace.
The first condition of their relationship that Aubrey had gotten Levi to understand was that absolutely no one could ever find out about it. This meant no sexual or even flirty antics outside the apartment. Though… they had found some creative ways to circumvent this rule.
Aubrey had chosen to wear a floral, yellow sundress for some fun. The weather was almost perfect for it, warm but not too humid. Levi had taken notice of the beautiful dress but kept his hands to himself. His eyes, however, wandered over to look at his big step-sister every few moments. He was occupied with his game but it didn't require that much focus. The boy's own wardrobe was much less fun, his go-to outfit was just shorts and a t-shirt. He didn't really know how to show off that well, but maybe thought that would be pushing it a bit too far.
Making a final turn, Aubrey pulled the car into a parking garage. She enjoyed having the car to get to classes and take Levi to extracurricular activities, but parking was a costly hassle in the city. This was to closest place to the supermarket that didn't charge the entire cost of their groceries for more than an hour's stay. Maneuvering into a parking space, the step-siblings swung the car doors open fully. It was nice to not be packed in between other cars, the garage was mostly empty.
"Ahhhhhhh." Aubrey stretched her arms up and arched her back as she got out of the car. The material of her dress tightened over her bra. It was half a natural motion and half a tactic to get Levi's attention. The boy tried his best not to stare, but he hadn't seen her in that particular dress too often. It suited her body very well. The light material flowed over her curves in all the right ways. Plus, the skirt was right at her knees, showing off her legs a bit.
Grabbing her purse, Aubrey led them out of the garage and down the street. It wasn't more than a three-minute walk, easy enough. But she still had Levi hold her hand to cross every street. He was a little peeved by the insinuation that he needed to be treated like a little kid. But the thought quickly left his mind once they got to the store.
They had a good routine for shopping here, Aubrey would push the cart along and Levi would find the items he knew to grab in each isle. They'd been doing this for several months now so it was getting to be an easy process.
"Hey, which one?" Levi held up two boxed casserole meals. Well, at least most of it was easy.
"Hmmm, they both seem good to me." Aubrey moved in to look at the boxes the boy was holding. She rested a hand on his shoulder and then slid it to his neck. She quickly pressed a fingernail to his soft skin and gently pulled it down. One of Levi's favorite sensations were those exact fingernails scratching down his back as he plowed into her. Aubrey had found it was an incredibly effective way to tease him in public. Her eyes never left the boxes of food.
"We're gonna need a few boxes, just get some of both." Aubrey ruffled his hair and went back to looking for other things. Levi stood still for a few moments, body tense from just that tiny stimulation. He wanted that again, but harder and longer. They just had to make it home. Just a little bit.
Aubrey had seen a few guys check her out as they walked around. It wasn't surprising and she was very aware of what kind of attention she could attract. Mostly they were respectful, only a handful of times she'd had to deal with a creep. One big advantage of going out with Levi was that he naturally disincentivized guys from approaching her, not many of them wanted to deal with a kid.
Levi was completely oblivious to this. He focused entirely on running and grabbing the right items to get them through the trip faster. Aubrey took some perverse pleasure in knowing that her little step-brother was too pure to realize that others might be jealous of his privilege as her lover. Lots of guys in this very store would give anything to use Aubrey in the ways Levi was going to when they got home.
They continued shopping without much issue, just some long touches and step-sibling-appropriate banter. Some of the staff here were familiar with them, another reason to be very careful. But their actions came off as more playful than incestuous. A very observant eye might have caught a glance that was just a bit too long or a light touch that lingered for more than a moment, but no one was even minding the duo. The store was relatively busy, lots of people went shopping on the weekends. But in a way that helped them slip unnoticed in the crowd of shoppers.
Finally getting in the checkout line, Levi stood next to his step-sister and leaned his head against her arm. They both wanted so much more, to grab and grind and thrust with all of their might. The sexual relief of the morning was just a distant memory now, more current needs were pressing them forward. They were, thankfully, able to keep those needs in check for the last leg of their trip.
Grabbing up all of their bags, the step-siblings headed back to the parking garage. The trip was uneventful, though Aubrey once again awkwardly had them hold hands to cross the streets. The grocery bags making it a bit cumbersome. Finally unloading everything into the trunk of the car, they both rushed to get the doors open.
"How fast can we get home?" Levi fidgeted in his seat with hands pressed into his lap.
"I will drive in the safest way possible." Aubrey breathed heavily. Her statement was as much directed at herself as Levi. "But we are getting there as soon as I can possibly get us there."
The drive went smoothly, if very tense for the two frustrated lovers. Aubrey had to put an extreme amount of effort into focusing on the road. She was grateful for the light traffic, even if she did know most of these roads pretty well by now. Levi closed his eyes for most of the trip and tried not to be a distraction. He'd managed to not pop a boner while they were in the store but his cock was getting harder and harder now.
Rounding the corner onto their street, Aubrey got a wicked idea. It was a straight shot to their apartment's parking garage. Hardly any other cars. A very sexually frustrated passenger…
"Hey, look here." Aubrey tapped her knee. Levi snapped to her instruction, unsure of what she intended. The older girl pinched a bit of her dress and pulled up, revealing more of her thigh. A quick brush of her hand left most of the material bunched up at her waist. It was just enough to be tantalizing.
"Ouhhhhah…uhuh." Levi openly stared at her legs, entranced by the daring display. Also now sporting a properly rock-solid boner. Aubrey just chuckled and kept her eyes on the road. Just a few more minutes.
After parking in their normal spot, Abrey readjusted her dress. Levi was already up and out of the car, waiting to get the bags.
"Carefully. Slowly." Aubrey knew she would have trouble heading her own warning. The pair had several bags of groceries slung across their arms but moved through the garage like overeager animals.
Finally, finally, the lock to their front door clicked open and allowed the desperate lovers back into the privacy of their own secret world. A deluge of bags was strewn onto the kitchen floor and then it was on.
Levi's much smaller body collided roughly with Aubrey's, the two of them feverishly kissing while tugging on articles of clothing. The height difference between them made everything a bit trickier. Levi's hands had instantly gone under his step-sister's skirt and were clumsily trying to remove her panties in a mad dash to get to her pussy. Aubrey was too busy working his belt loose to help.
Shorts now around his ankles, Levi pawed at Aubrey's ass while his tongue danced with hers. Their collective moans filled each other's mouths, barely leaving space to breathe. Their bodies demanded more, faster, harder, now. It was a lust crazed debacle of desperation. Never breaking their kiss, Aubrey shimmied out of her panties and lifted up his shirt.
Finally letting their mouths part, Aubrey fully pulled Levi's shirt off. She then dropped to her knees, hungry for that boy cock. They both tugged at Levi's underwear, unveiling his diamond-hard erection to the lustful gaze of his big step-sister. She shot her eyes up at him and gently kissed his tip. The boy shuddered but he needed more.
"OHH, fuck yes!" Levi groaned as Aubrey took his whole member into her mouth, swirling her tongue over the sensitive rod. He grabbed two fistfuls of her hair and pushed. Aubrey loved the feeling of him getting rough, his cock was just long enough to reach her throat without being unpleasant. She let him pump his hips a few times before she pulled back off his cock.
"If you're gonna fuck me, then do it right." Aubrey spun and bent over the table, hiking her dress up to her waist and spreading her ass cheeks. Levi immediately dove face first into her dripping wet snatch which caused the older girl to cry out. He wanted to fuck her, yes, but a ripe pussy in his face was too much of a temptation to not eat out. He only indulged for a few moments before leaving Aubrey to go fetch the stepstool.
Their height difference meant that Levi couldn't align himself if Aubrey was standing comfortably. They had quickly learned a small stepstool made all the difference and now kept one discreetly tucked in a corner of the kitchen. It was a bit of a hassle to go and fetch every time they wanted to fuck like this, but the result was well worth it.
"Get that fucking dick in me right now." Aubrey was rubbing her slick pussy as Levi finally stood in position. With some assistance, he lined up his throbbing tip with her entrance and rammed it home. Both step-siblings cried out in overwhelming ecstasy. Their backs arched and eyes screwed shut, embodiments of sexual bliss.
Acting on pure instinct, Levi began to move his hips. A slow stroke at first but quickly worked up to a proper ramming speed. His hands grabbed at his step-sister's hips, using them as leverage for harder thrusts. The delicious sounds of colliding flesh echoed in the room. Her body was his to use right now, to extract as much pleasure from as possible while inflicting that same pleasure upon her.
Aubrey had stopped thinking when her step-brother's cock penetrated her cunt. 'No thoughts, head empty' kind of pleasure resonated in her entire being. She was just able to keep her body steady, breasts mashed into the table. It was thankfully barren; they didn't keep anything on the table for this exact reason.
Levi grunted and kept up his relentless assault. He was determined to last a long time after the embarrassment of this morning. The hours of teasing he'd been subject to didn't help, but he managed to endure through sheer willpower. The lovers kept at it for what felt like an eternity. Cock and cunt afire with beautiful spasms of pleasure. Aubrey was now cognizant enough to wonder if her little step-brother would ever cum. Maybe he could go on like this forever.
That thought triggered her own orgasm, sending her into the stratosphere of pleasure as she screamed into her arm. Levi felt her clench around his cock and beamed in self-pride. Now ready to reach that peak himself, the boy let the full sensations of the moment wash over him and it only took a few more strokes to get him there.
"Auuubreey, I'm gonna cum in you!" Levi gave warning before his cock began to throb and pulse with huge waves of spunk. He shuddered and gripped her hips even harder, his small hands leaving telltale marks on her soft skin. Riding through his orgasm, the boy let out a long moan.
"Haaaaa~." Aubrey basked in the familiar feeling of her step-brother's virulent cum being pumped into the depths of her love tunnel. Maybe this time it would…. Possibly….
The exhausted step-siblings were locked in that position for a few moments, Aubrey splayed out on the table and Levi leaning forward on his step-sister's body. His small, boyish hands slowly loosened their grip on her hips and slid over her lovely ass. His cock now deflating, Levi gingerly pulled himself from the messy pussy of his older step-sister.
"Fuck. That was reeeeally good." Aubrey heaved with each breath. She bunched up her dress and pushed herself up off the table. "Could you unzip me?"
"Yeah, yeah." Levi had plopped into a seat at the table. He sluggishly moved over to pull the zipper on the back of Aubrey's dress. The older girl slipped out of the garment, letting it fall to the ground. Her bra came off in a flash and shoes were soon to follow. The now naked college student took another moment to steady her breath.
Levi stared openly, admiring the bountiful curves and supple skin of his lover. Though sexually exhausted, the boy did still crave physical affection. He moved in to hug her from behind, their naked bodies igniting with warmth at all of the skin contact. Levi nuzzled into her back. "You feel good."
"Ahh. You do too." Aubrey reached back and grabbed his shoulder. Now a bit alleviated from her sexual haze, she glanced around the room. "Oh shit, we need to put stuff in the fridge!"
Both step-siblings moved to sort through the bags of foodstuff and find what needed to be refrigerated. Aubrey opened the door and felt the cold air all over her body. She sorted everything inside while Levi rummaged for the things that needed to be put away. They quickly got that task done and then sorted the rest of the non-perishables.
"Here clean yourself up too." Aubrey handed her step-brother a pack of wipes as she was in the process of tidying up her own body. A proper shower would probably be in order for both of them but there wasn't a real rush. They would probably be dirty again in just a few hours.
"What are we gonna do for the rest of the day?" Levi casually asked as the two sorted the very last bits of food.
"I'm going to work on writing a paper for class. But you're free to do whatever you want."
"Yes!" Levi hopped away to his room, probably to boot up his gaming console. He was rarely allowed to play much during the weekdays, so weekends were also fun for that reason.
Aubrey watched as his naked form scurried from the room. She chuckled to herself and ran a hand over her chest. They were both sexually satisfied now but it was a fun guessing game to figure out which one of them would get worked up again first and initiate the next round. If previous weekends were anything to go by, they had at least two more good rounds left before the day was over.
"Levi!! Come pick up your clothes before you start that!" Aubrey exasperatedly swept his things into a pile on the floor. The boy was a bit lazy with cleaning up after himself, so it fell to Aubrey to make sure the apartment wasn't turning into a disaster area. Plus, a full set of each of their clothes on the dining room floor might have been a bit too suspicious to explain away if they had an unexpected guest.
The rest of the early afternoon was quiet. After putting on some casual clothes, Aubrey had started work on her paper and it was now almost complete. She was lounging on their small couch and taking a few moments to relax. A couple of nights ago she had sat Levi down on this very couch and ridden him hard. That had been fun… A small notification on her laptop pulled her out of her thoughts. She clicked onto the incest forum and found a message waiting.
It was from Polaris_34, the user she'd been communicating with quite a bit. He was apparently around her age and had a step-sister who was just a little older than Levi. Due to circumstances that he hadn't fully gone into, the two of them were on their own. That had led to their own relationship blossoming into a romantic and sexual one.
Aubrey, of course, took everything he said with a grain of salt but he seemed genuine and had been very helpful so far. He had given tips to switch from 'lover mode' to 'step-sibling mode' quickly and implored that they keep up their normal social lives outside of the house. Aubrey had unfortunately neglected a few friends and obligations in those first few nights with Levi. Moreso, he had also provided some good codewords that the step-siblings had taken to using. Signals to warn of a surprise visitor that had saved their lives on a few occasions.
The message read: 'Hey, I told my step-sister about our conversations and she seems interested in chatting with you. Would you be up to that?' Aubrey was more than curious, getting a better picture of these people's lives would be very informative. Levi hadn't really expressed any interest in the forum or the people on it beyond just casual questions.
She typed up her reply that yes, she would be more than happy to, then closed her laptop. Polaris usually took a while to respond. Just then Levi wandered back into the room. He had changed into a soft grey shirt and shorts that were meant for relaxing. "Auuubreeey, I'm hungry."
"Mm, I kinda am too. What do you want to eat?" Before Aubrey could get up, her little step-brother knelt in front of the couch and leaned over to rest his head in her lap. Gently setting her laptop aside, Aubrey smiled and rubbed his hair. "You're way too cute. Keep that up and we might have to postpone lunch for other things."
Levi turned his head and rubbed his face into her crotch. This caused Aubrey to tense and clench her thighs together. But he only hummed and then quickly stood up. "Maybe after, I'm really hungry."
The boy skipped over to the kitchen and began skimming through the options in the fridge. Aubrey huffed indignantly, the nerve of this boy to act all affectionate and then up and walk away! He was just a kid after all. But she would get him back for that. At precisely the moment he would least expect it.
Eager to see what kind of fun their after-lunch activities would entail; Aubrey followed her step-brother over to the kitchen to start cooking.

"What are you in the mood for today?" Aubrey typed away at her laptop, brining up a few sites to peruse. A cable connected it to the TV in Levi's room, projecting the screen for a better view. It had been a few hours since the two had eaten lunch, the day was starting to wane but that wasn't too much to worry about. It was the weekend after all.
"Mmmm, anything really." Levi plopped onto his bed and happily sighed.
"Alright, let's find something interesting then." Aubrey scrolled through the lists of videos, curious to see what her little step-brother would gravitate toward.
"Oh, that one, bottom right!" Levi pointed out a particular video of a busty woman in fancy black lingerie on a bed. Aubrey checked the preview and found it was satisfactory to her tastes as well.
Aubrey had known her step-brother was watching porn even before their sexual relationship blossomed. He had been pretty protective of his tablet and always had it locked away. She saw direct evidence after walking in on him that first time. After getting comfortable with their new boundaries, Aubrey had taken it upon herself to teach her little step-brother where to find the good stuff. She'd been around the internet long enough to have a few tricks.
Their tastes didn't always align, but lots of simple amateur videos were good enough to get them in the mood. They also shared some inclinations to certain kinks, though it was much harder to find good quality videos for them. Aubrey found it amusing to go through literal porn with her kid step-brother and trade opinions on camera angles, lighting, vocalizations, outfits, and positions. The two of them had started a few playlists of their favorites as well.
The two of them rarely fucked while watching, instead masturbating each other to optimize the viewing experience. Aubrey had a vibrator that she had given Levi some instructions on how to use effectively. This was basically the only time the toy got used anymore. They'd been planning on buying a fleshlight to try out but hadn't gotten around to it yet.
Aubrey clicked play on the video and noted how long it was. Twelve and a half minutes, perfect. She casually dropped her shorts before joining Levi on the bed. The duo snuggled together and propped their heads up with pillows as the woman in the video started showing off. "I'm thinking we do something special for this one. Get naked and then put your hands under your butt."
"Uh, okay." Levi was a bit confused but happily complied with his step-sisters' instructions. He flipped his shirt off, tugged his shorts and underwear down and then pushed his hands underneath his body. His cock was semi-hard already but it was getting stiffer with each beat of his heart.
Breathing into his ear, Aubrey gave Levi instructions while running the tip of her finger over his growing length. "Keep watching the video. Don't move your hands, no matter what. Just relax."
Pulling away for just a moment, Aubrey reached for the bottle of lube she'd brought with her. The stuff was quite good, very slick and easy to manage. It had been part of her 'necessities' purchase binge when sex became a part of their daily lives. The bottle was running low now, they liked to have these mutual masturbation sessions every few days.
Popping the cap, Aubrey let a small bit squirt into her right hand to feel it. Nice and slippery but also quite cold. She continued to coat her palm and fingers in the lube, rubbing them together to get the substance to a nicer temperature. Discarding the bottle to the side, she pressed herself up against Levi and gently worked her slick hand over his erection. She made sure it was entirely coated in the lube before gently tightening her grip around the base.
Levi groaned in satisfaction as his big step-sister made her first slow stroke up his cock. He wasn't sure why she wanted his hands hidden, they normally played with each other at the same time. This was nice but odd. Oh well, he trusted her so it must be for a reason.
The video continued playing, both step-siblings kept their eyes on it as much as possible. The woman was now completely naked, having slowly stripped out of her lingerie and spent a while playing with herself. A man appeared in frame and joined her on the large bed. He was already naked and sporting a nice-looking stiff cock. The two of them were evidently passionate about each other, making out tenderly while their bodies pressed together.
"Good choice. They look really into it." Aubrey commented as her hand reached the tip of Levi's cock. She twisted her wrist to get even more stimulation around his sensitive head and then pulled back down the shaft, agonizingly slowly. She took the time to really appreciate his tool. This cock had been inside her so often that she'd gotten used to its shape and size. She also knew exactly where his most sensitive spots were and how to exploit them.
"Ahaahhhh, yeah…they look… good." Levi wasn't used to this kind of treatment. His hips trembled and bucked on instinct, eager to get Aubrey to move her hand faster.
"Uh-uh, no moving. Just watch." Aubrey smiled. She was laying on her side but managed to get her other hand to press down on Levi's hip. This was going to be fun. Her little game continued for the next few minutes. Levi was such a good boy, eyes fixed on the screen and body completely unmoving. His breathing was fast and shallow but otherwise he was able to keep himself in check.
As the people in the video changed positions, Aubrey finished a full stroke and stopped her hand at the base of her step-brothers' cock. She squeezed ever so gently but did not start another stroke.
"Huh? Whaaa…?" Levi panted and squirmed.
"Oh, just taking my time. Doesn't that look fun though?" Aubrey nodded toward the TV. The couple were now fucking hard, every thrust accompanied by a satisfying clap of bare flesh. "Just going all out, hammering away, not a care in the world. It would feel so good, wouldn't it?"
Now whimpering, Levi desperately wanted to move his hands. More so, he wanted to fuck Aubrey hard and fast. He needed to cum and soon. His body was just way to wound up, it needed release in any form. He stealthily nudged one of his hands and tried to hump up.
"Hey, I told you not to move." Aubrey sternly scolded the younger boy. She then softly whispered in his ear; "Be a good little boy and I'll make it worth the wait."
Levi's only response was a long, drawn-out moan as he pressed his head back into the pillow. He knew his step-sister could be a bit bossy, but this was on a whole other level. His body was on the verge of losing control and she was still calmly lying beside him and moving her hand at a snail's pace.
This exquisite torture continued for the remainder of the video, which ended in a lovely cum shot across the woman's abdomen. Levi whined and nearly came from the sight, his cock aching for more stimulation as he approached his orgasm. Aubrey had other ideas. She snapped her hand open and pulled away from the twitching rod. She stared, enraptured, as the tip leaked precum and spasmed, so close yet so far. It was beautiful.
Levi clenched his fists underneath himself and grit his teeth. He'd never experienced anything like this, his mind was numb from the high of getting so close to orgasm and having it ripped away. The pleasure was mixed with a hollowness that needed to be filled. It felt like… maybe the next high would be even better.
"I think this is a good lesson in why you don't leave people hanging. Why it's good to finish what you start." Aubrey poked at the base of her step-brother's cock, causing it to wobble. She knew it was a bit of a harsh lesson for what he'd done earlier, but oh was it so much fun.
"Mhm! Yes, yeah, yeaaaaaaaahhhhh! Please!" Levi babbled and muttered while still keeping his hands restrained.
'Alright he's had enough. I hope he shoots a giant load for me.' Aubrey was just about to give her step-brother exactly what he wanted when a loud buzz interrupted them. It was coming from Aubrey's phone on the nightstand. One glance and Aubrey jumped up to grab at the device.
"Shit, it's Mom. Don't. Move." She fumbled with the phone in her left hand while pointing at her whimpering little step-brother with her lube covered right hand. Fortunately, the porn video had stopped playing and was silent. Steadying her anxious heart, Aubrey answered the call.
"Hi Mom!"
"Yeah, we're doing good."
"Oh, not much. We did some shopping and then just kinda relaxed."
"Mhm, yeah it's been a busy week and it's nice to have a free day."
"Levi?" The step-siblings locked eyes. "He's taking a shower right now, but I can tell him to call you when he's done."
"I'm watching some shows, probably going to shower as well once he's done. Then we'll start dinner."
"Yeah, it's a real exciting life."
"Okay, yeah. Yaehyeahyeahyeahyeah. Yes, I get it." Aubrey slipped back onto the bed and very slowly settled in beside her naked step-brother.
"Alright. Love you too Mom. Bye." She carefully clicked the end call button and chucked the device off the side of the bed.
"God, she really has the worst timing." Aubrey breathed a sigh of relief. "I promise that was not part of the plan."
"Mhm." Levi nodded and shook his hips; cock still rock hard and aching for relief.
"Ah-ha. Well then…" Aubrey hovered her lubed up hand over her step-brother's needy cock. In one fell swoop she gripped the engorged member and began to pump it fast and hard, milking it for all it was worth.
Levi cried out and almost instantly was brought back to the verge of orgasm. Aubrey locked her eyes on his adorable face, writhing in pleasure, and kissed his cheek. She continued her fast and hard strokes, giving him exactly what he'd craved a few minutes ago.
Both step-siblings shuddered as Levi finally reached his tipping point and began spewing ivory ropes of cum all over himself. The shots got all over his chest and stomach, a smattering of savory delight. Overwhelmed, the young boy simply went lax and let his big step-sister rub even more spunk from his spent phallus.
"Such a very good boy." Aubrey once again kissed her little step-brother and then repositioned to lick all over his body, slurping up his cum like a delicacy. It wasn't quite the same as a creampie but the more of his baby batter she could get into her body, the better. After tongue cleaning his smooth skin, Aubrey grabbed them some wipes to clean up with and then cuddled with her favorite boy toy.
She held him close and whispered sweet words into his ear about how good he had been and how proud she was. She asked if he felt okay and if he needed anything. Levi was still processing the new experience but generally felt pretty good about it. It felt bad at first but the high that came after lasted so much longer.
"I'm glad you feel that way. You looked so good when you were right on the edge. So desperate and cute." Aubrey toyed with her step-brother's soft cock, then ran her fingers along his abdomen.
"It was weird, it felt bad and good sort of all at once. But you haven't gotten off yet! Should I…" Levi slid a hand between his step-sister's legs.
"Ah, as much as I would love that, you've got to call Mom back and then definitely take a real shower." Aubrey patted his stomach. "Thank you for being considerate though."
"Okay." Levi disentangled himself from his step-sister's body and lazily swung over the side of the bed. He stood and stretched; his legs were feeling weak from the powerful orgasm. The boy meandered to the door and looked back. "Can we shower together?"
They had tried this very idea before and found the tiny shower of their apartment wasn't great to accommodate two people. But it did make for some wet and slippery fun. Aubrey pondered the request. "Ehhhh… go call Mom and I'll think about it."
They did end up showering together. Glistening wet skin grinding and slipping in every way as the two pressed together. The small confines of the shower made it very difficult to properly get clean but that didn't stop the step-siblings from trying. Levi was constantly distracted with Aubrey's slippery breasts, kneading the pliant flesh and rubbing his face between the orbs. Occasionally pinching or sucking her hard nipples. She, in turn, moaned loudly while scratching his back and rubbed her thigh into his crotch.
Aubrey had a small hope that she could rouse Levi into another round while they were showering but the young boy wasn't fully recovered yet. Though he greatly appreciated the rare pleasure of showering with his big step-sister. The duo finally got rinsed for the last time and hopped out of the shower. Levi handed his step-sister her towel and began to dry himself off as well.
"I think we're just having leftovers for a quick dinner. Could you get the table set and stuff out of the fridge? I'll be out in a sec." Aubrey smiled at her little helper. He was quick to dry off and rushed out of the room. She would take a bit longer to get her hair dry.
The step-siblings had a quiet meal with a bit of flirty touching. In private they could rarely keep their hands off of each other for more than a few minutes. Aubrey especially was still worked up from their fun and hadn't gotten off in hours. Once they had eaten and put up their dishes, she decided to fix her situation.
"Oh no, where do you think you're going young man?" She grabbed Levi by the shirt as he walked past her. "I think you owe me an orgasm."
"Oh. Sure!" Levi happily chirped. He slid into his step-sister's embrace and the two kissed. Aubrey hunched down to reach his lips, fawning over his body with predatory intent.
"Go lay on my bed." The command sent Levi skipping over to Aubrey's room with her following close behind. The college girl took perverse pleasure in anticipating what she was about to do.
She watched as her little step-brother hopped onto the bed and stared at her with innocent eyes. So beautiful and delicate. Hooking her thumbs into her shorts and panties, she pulled both down in one smooth motion. Almost in a trance, she kissed his lips and then mounted his head. They had perfected this holy act over many sessions. The angle, weight distribution, time to breathe, all of it was honed to the highest pleasure inducing degree.
Aubrey lovingly sat down on Levi's face and moaned as the young boy used his tongue to assault her dripping wet pussy. She screwed her eyes shut and gripped onto the headboard of the bed. God, his technique was incredible. She forced herself to glance down at her little step-brother munching away. His arms were wrapped around her thighs, eagerly pulling her down more. She loved feeling those small hands pull at her body.
Already properly excited from the day's activities, Aubrey knew she wouldn't last under the skilled oral treatment of her little step-brother. Rather than prolong it, she played into the desire and let her hips move freely. She ground her soaking wet cunt into his face and used a hand to pinch her own nipples.
"Oooohhhhh, yes, I'm gonna cum so hard. Just like that baby." Just as Aubrey was getting close Levi tapped her hip twice, the signal he needed a breather. Aubrey quickly lifted her hips, a bit embarrassed she had forgotten to let him breathe.
Levi panted for a second and then pulled down hard on his big step-sister's divine body. "I'm good, I'm good! Go all the way."
Emboldened by his words, Aubrey rode his face hard. She bucked and trembled as his tongue lashed around her pussy, firing up her neurons to reach that pivotal moment. She glanced down once more to see Levi staring back up at her, sweet eyes full of lust and adoration. Finally pushed over the edge, the college girl squealed as her orgasm overtook her. Levi knew to focus on her clit once again, as best he could. He was happy to feel her full weight, now even more so that she was pressing into him and clamping her thighs around his head.
The spectacle lasted just long enough for Levi to tap for another breath. Through her bliss-induced haze, Aubrey knew well enough to let up for her step-brother's sake. She felt him scoot out from under her and moved a hand to her pussy, just enough stimulation to keep the pleasure going a bit longer.
"That was fun!" Levi quipped. His face was a mess of his step-sisters' pussy juices.
"Yeah…" Aubrey collapsed onto her bed and sighed contently.
The step-siblings cleaned themselves up and then snuggled in bed. It had been a long day and tomorrow promised to be just as eventful. No concrete plans but more than enough time to figure it out. They had to take advantage of the weekend while it lasted. Finally getting ready to sleep, the duo curled up in each other's embrace. Warm bodies pressed together to ward off the coldness of the night. The world outside could be heard in small bursts of traffic and wind but everything in their small universe was still. At least… mostly.
"Um, Aubrey."
"Hmhhh...?" She could already feel her step-brother's hard cock gently grinding against her hip.
"Could we, ya know. One more?"
"You have way too much energy. Nnnnnhh. Fine, you better make it quick."
Levi lazily humped his way to depositing another thick load inside his step-sister. Aubrey, though tired, was happy to have one final injection of her step-brother's seed. The exhausted pair then finally gave in and fell asleep, bodies tangled together in wholesome incestuous love.

Chapter Text
"Ahhhhhh!" Levi shuddered as he fired his first cumshot of the day into his step-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 step-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 step-siblings hadn't indulged in their normal fun.
"Yeah, yeah. Just go finish getting ready." Aubrey could still taste her little step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-sister's shoulder.
"Okay. I'll see what I can set up." Aubrey rubbed her step-brother's hair and they continued their show.
**********
"Mhmm!! Slower." Aubrey growled at her little step-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 step-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 step-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 step-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 step-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 step-sister to voice any concerns.
"Okay. Faster." Muscles finally relaxed; Aubrey was really starting to enjoy the filling sensations of her step-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 step-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 step-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 step-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 step-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 step-siblings enraptured in their own carnal desires. Levi treated his step-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 step-brother came in her ass. Her own fingers were flashing in and out of her cunt, taking her to an inevitable conclusion.
Both step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-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 step-brother splayed out on the bed with the strapon still inside him.
After recovering and cleaning up, Levi lavished his big step-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 step-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 step-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 step-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 step-brother was dishing out.
"I wanna knock you up so bad! Breed my big step-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 step-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 step-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 step-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 step-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 step-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 step-brother's words. "Roleplaying. Roleplaying breeding. That was amazing, but it was just for fun."
"Mhm." Levi extracted himself from his step-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 step-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.
