Yor Briar’s Apartment
Blissful hums echoed from within the humble kitchen of a certain covert assassin’s apartment. The bright rays of sunshine glistened against Yor’s fair skin while she continued working on breakfast. It was only once every month that she was able to see her beloved, so she knew that she had to make the best of it while she had the time. “Mmm…I hope he enjoys these pancakes. He used to love them when he was a kid.” A small giggle escaped the assassin as she thought back to her childhood and remembered how innocent she used to be.
‘I can still remember my first kill like it was yesterday. That was the very first time I was able to use piano wire to garrote someone. Ahh…sweet memories.’ Yor was still basking in her past when two firm hands suddenly groped behind her apron. They wiggled eagerly against her chest, causing her to coo in pleasure, but otherwise barely moved as if accepting it like it was an everyday occurrence. Unflinching, she turned to the man standing behind her and happily greeted him with a beautiful smile. “Good morning, Yuri. Did you sleep well last night?”
Yuri, naked as the day he was born, happily nodded as he continued fondling his older sister’s breasts. “Of course, my darling sister! It’s been almost a month since I’ve been able to hold you in my arms and feel your sweet warmth. Oh, if only I could quit my job and simply stay by your side for all eternity, what a joyous day that would be!” He bemoaned while grinding his flaccid penis against his sibling’s slit. Like him, she was completely nude, save for the pale apron that was tied across her body. Such a gorgeous sight of seeing his beloved sister in her illustrious naked apron costume made his cock slowly begin to stiffen against her crotch.
“Yuri~!” Yor squealed, feeling her brother’s phallus twitch against her squelching folds. With each throb, she felt her pussy lips become wetter by the second. “…I can’t believe you’re still able to become erect after all we did last night. The couch, the dining room, the bath, the shower, the bedroom…you made love to me in all manner of rooms. Just where do you get such stamina?”
“For my love for you of course, Yor! I thought that was obvious! You’re my darling, sweet, beautiful sister, so it’s only natural that my body wants nothing more than to have sex with you!” Yuri answered, still grinding and pumping his hips against his sister’s behind. He felt her plump ass cheeks jiggle with every thrust of his, making him even hornier than before. All the while his sibling stood there, giggling, as she kept focus on the bubbling pancakes that were on the stove. “Yor, let’s have sex again. Right here!”
“Yuri…I’m making breakfast right now. If I don’t pay attention, then the pancakes will burn.”
“But I don’t care about the pancakes! I want to have sex with you! Pleeeeeeease?”
Yor pouted as she watched her younger sibling beg and plead. It wasn’t as if she didn’t want to, but it had been quite a while since she’d been able to make food for her sweet little brother. Once more, she tried to dissuade him, only to receive puppy-dog eyes in return. And like all the other times he had used such a cute expression on her, Yor could not give herself to say no to her little brother. “…Okay. But not too rough this time, Yuri, I mean it! And no anal either. My butt’s still sore from last night…”
Yuri, absolutely ecstatic, beamed and laid a passionate kiss onto his sister’s cheek. “You’re the best sister in the world! I love you, I love you, I love you!” Hearing her sweet-sounding giggles made his heart go aflutter and he could hardly contain himself anymore. Crouching to his knees, he was eyelevel with his sister’s cushiony tush and simply marveled at how splendidly supple and curvaceous it appeared. There was not a more perfect ass in all of Ostania…no, in all the world that surpassed Yor Briar’s.
Like always, he watched as his beautiful sister teased him by wiggling her butt in front of his face, nearly smacking him with her curvy cheeks. Yuri smacked his lips hungrily, drooling excessively as he lolled his tongue out of his mouth and dragged it across Yor’s plump butt. His sister shivered as he layered her ass with licks and kisses. After a few minutes of continuously repeating that, he then stuffed his face between her cheeks and began slurping up all the juices that were leaking from his sibling’s dripping slit.
“Yuri~! Your tongue feels so good!” Yor cried out, gripping the stove with such power that it nearly cracked from the pressure. ‘Brothers shouldn’t be doing this to their sisters, I know…but then why does it feel so good when Yuri does this to me.’ Her body convulsed, feeling the familiar sensation of an orgasm surge through her body. Whether it was because his tongue was that skilled, or the fact that it was her brother’s tongue that was wriggling inside her vagina, or simply the case of being both, she did not know. All that Yor knew was that she loved her brother with all her heart, and she knew that being able to explore her body, intimately and sexually, was what made Yuri the happiest.
‘It all started with simple kisses on the cheek every time he excelled at his tests. But as time went on and he got older, those innocent kisses became more lewd and vulgar. Kissing a man has always frightened me…but with Yuri…all of that embarrassment and fear melts away when his lips touch mine.’ Yor mewled, biting her index finger to keep her moans in check so as not to disturb the neighbors. While marriage and intimacy between cousins was legal in Ostania, it was the opposite when it came to direct siblings. Still, regardless of the taboo nature of their relationship, both of them didn’t care about the potential ramifications that it could bring upon their lives.
Pulling himself away from his sister’s butt, a strand of saliva connected Yuri’s tongue to Yor’s pussy lips. He then lapped it up before pushing himself back up and crashing his lips onto his sister’s. His tongue wrestled against hers while his hands vulgarly groped her massive tits from underneath her apron. The two moved away from the stove as their passion escalated, further deepening their taboo embrace with a perverted kiss. Their tongues lolled from outside their mouths, dripping saliva onto the ground as well as Yor’s pale apron. Yuri’s fingers rubbed against Yor’s increasingly stiffening nipples, pinching and pulling on them teasingly while he listened to his elder sister’s harmonious whimpers.
Unable to hold himself back any further, Yuri thrust himself into Yor, causing her to let out yet another pleasured squeal that nearly shattered all the glass in the apartment. Immediately upon entering her, he began humping her as fast as he could. He left one hand to continuously fondle his sister’s giant breast while using the other to squeeze a handful of her supple butt. His hands molded them both from inside his harsh grip, squeezing and rolling both her ass and tit as he repeatedly fucked her from behind. All the while, their incestuous kiss continued, never breaking once as the Briar siblings pressed themselves deeper onto the other.
“Yor…I love you. More than anyone in the world!”
“I know. I love you too, Yuri, with all my heart.”
With each declaration of love that Yuri repeated, Yor’s insides tightened against her younger brother’s erection. Feeling his muscular body pressed up against her back made her quiver with excitement and caused yet another orgasm to surge through her. She could feel his cock pulsate against her ribbed walls, nearly barreling towards the entrance of her womb. ‘Yuri was so relentless last night that we ended up using all the condoms. I can’t let him cum inside me, no matter how hard he pleads.’ Clenching her teeth as she convulsed, Yor began pushing her ass back in tandem with her brother’s thrusts, which made his cock delve deeper into her pussy. “Yuri, you’re pounding me so hard! Be gentler…”
“Sis, you’re the one who keeps making me go deeper! Plus, you’re so damned tight that I’m not going to last long at this rate!” Yuri yelled as he feverously railed his sister from behind. He then wrapped his arms around her waist, pulling her deeper into their embrace. His tongue slid against her cheek, teasing her lips, while he shoved it back down her throat. Yor’s moans reverberated within the kiss, which drove him even madder with lust and increased the speed of his thrusts. “Yor, I’m close! Please, let me cum inside you!”
“Yuri, mmmmmph, you can’t! You’re, ahhhhh, not wearing a condom, plus…” Yor stopped, trying her best to stifle her girlish squeals. ‘…It’s not a safe day.’ She finished inside her mind, unable to say it aloud to her sibling. Instead, she gave him the sternest look she could muster, even as his huge cock was ramming itself deeper inside her pussy. “…You came enough inside me last night with all those condoms. If you want to cum, it has to be outside.”
“Siiiiiiiiiis…”
“Yuri, I said no!”
“…Fine.” Yuri relented, much to his sister’s relief. “Can I at least cum in your mouth then?”
Yor smiled serenely from her brother’s question. “Of course! Did you just want me to suck you off, or would you also like to use my breasts too?”
“YOUR BREASTS! YOUR BREASTS, PLEASE!”
Giggling at how adorably excited her brother sounded, Yor nodded. “Very well, since you asked so politely.” She then slowly pushed Yuri off her and got to her knees in front of him. His cock throbbed mere inches away from her face, shadowing it from the immense girth of her sibling’s erection. “Wow…it always amazes me at how big you’ve grown, Yuri.” She tittered, earning a self-conscious fidget from her sibling. “Hee-hee, you’re so cute when you’re flustered.” Slowly, she pursed her lips and gently laid a small kiss on the tip of Yuri’s cock. Yor heard him grunt in surprise as a bead of pre-cum seeped out of his slit and drooped down towards her lips.
Yuri watched with bated breath as his sister’s mouth neared the white hanging strand, groaning as her warm breath wafted over his stimulated cock. He looked as her tongue peeked from her lips and slowly lapped it up, slurping the Cowper secretion into her mouth within an instant. After she gulped it down, humming approvingly while she did so, Yor gazed up at her brother’s large, throbbing penis with an amazed stare. “Sis…” Yuri moaned, prodding her face with his dick impatiently, eager to move on to the blowjob.
“Patience, Yuri.” Yor chided her sibling, unfurling her apron near the shoulders and allowing her huge breasts to flop out in the open. She giggled, noticing Yuri’s dick twitch excitedly at seeing her chest so close to him. Grabbing his penis, she began rubbing the tip against her left nipple, and cooed as she felt the hard cock thump against her erect nub. A few strands of pre-cum stained her teat after she pulled it away and moved it towards her mouth. Opening wide, she gently enveloped her brother’s stiff erection into her gaping mouth.
“YOR!” Yuri shouted, throwing his head back as he felt the gentle, loving suckles of his sister. He had to use all his willpower not to cum then and there, gripping the countertop excessively as he panted. His eyes stayed glued to Yor’s seductive, slow bobbing and shivered as her tongue slithered along his throbbing veins. There was no greater joy then having his beloved sister blow him, especially when she was clad in nothing but her adorable apron. Her sucks were leisured but methodical, hitting all his sweet spots that made it damn near impossible not to shoot his creamy load down her throat.
Closing her eyes, Yor allowed herself to indulge in the base pleasure of sucking her brother’s cock. She gripped his balls lightly with her palm, making carefully sure not to use any of her superhuman strength as she did so. Tenderly, she rolled them within her hand and could feel how plump and round they were. ‘All of Yuri’s adorable sperm must be swimming around in there, so eager to ejaculate into me. I shouldn’t keep him waiting too long, otherwise his penis might start to hurt by how hard it’s getting.’
Yor, popping his penis out from her mouth, then moved her cushiony tits towards her brother’s erection and sandwiched it inside. The tip of his cock peeked out from her cleavage, spurting a bit of pre-cum onto her chest, and felt Yuri’s body quiver against her. Tittering, she teasingly grinned upwards at her brother, asking, “Does that feel good, Yuri?” It didn’t take long for him to hastily nod his head, which made her titters escalate further. “Good. Let me know when you want to cum and I’ll let you do it inside my mouth. Or you can do it on my face or breasts if you prefer.”
“Yor…” Yuri tearfully called out to her, fighting back the flurry of emotions that were threatening to burst forth. “…YOU’RE THE BEST SISTER EVER!!!” He yelled as he began thrusting forward into her breasts. With each pump of his hips, Yor’s tits wobbled crazily in the air. Their soft, pillowy flesh entangled his penis within them and beckoned it further. Nothing in the world made him feel safer than wrapping his cock inside his sister’s breasts. It reminded him of all the times Yor would greet him with a warm, loving hug every time he came home from school. Even now, and the two were far older than they were from those distant memories, Yor still made him feel just as loved and needed and safe.
‘One day I’m going to find a way to marry you, Yor. I promise.’ Yuri thought as he sped up his wild humps. As he firmly held Yor’s massive rack within his hands, the tip of his penis rubbed up against his sister’s pink lips, staining them with more of his precum. After a few more rams, she allowed his cock reentry into her mouth, and he threw his head back once again from how wonderful and tight her mouth felt. “Keep sucking, Yor! Please don’t stop! I want to cum inside your mouth! I want you to swallow all my semen down your throat! I want you to taste how much I love you!”
Yor couldn’t help but giggle at how cute her brother sounded as his voice became more high-pitched as he approached his impending orgasm. ‘Society might deem me a terrible sister for allowing my brother to pursue such a taboo relationship with me…but I can’t help but accept his strange love. Yuri…I love you. More than anyone in the world.’ Readying herself for what would no doubt be an explosive ejaculation, her eyes widened as she felt a torrent of sperm come spurting into her mouth. It was so much that her cheeks puffed from all the semen that was filling her. A few bits of semeny spittle leaked out of her lips, but she managed to keep the majority of her brother’s cum inside her mouth.
With each bout of semen, a loud and throaty gulp echoed from within the kitchen. Both her mouth and her tits were quickly becoming marked with her brother’s semeny stains, utterly drenching them with white, stodgy streaks. Yuri continued thrusting his hips forward, hellbent on keeping the euphoric feeling of ejaculating inside his sister’s mouth. “Yor…keep sucking. Don’t stop until I’m all soft and flaccid.” He moaned, feeling her respond with incoherent garbles that reverberated onto his softening erection. Still, just like he asked, his sister complied and continued sucking even as his cock became softer inside her mouth.
Yuri leant forward, pressing his forehead against the wooden shelf above the counter. He allowed himself to relax and revel in Yor’s gentle, maternal suckling. After today, he would have to go back to his secret job in the State Security Service, which meant he would be away from his beloved sister. It hurt him every time he had to leave her, but he knew deep down that it was necessary. For without his contributions towards the SSS, the world would no doubt devolve into chaos and war would once again break out between Ostania and Westalis. All that mattered to him was protecting Yor from any potential danger that could surmount due to the violence of war and if he had to spend large bouts of time away from her to do it…then so be it.
As he heard the last loud gulp come from his sister, Yuri pulled his wilted penis out from Yor’s mouth. “Yor…kiss me, please.”
“Geez, you’re as spoiled as ever, Yuri.”
Even as she outwardly complained to him, Yor still leapt up to her feet and pursed her lips towards him. Slowly the two pressed their lips together, which quickly devolved into another passionate and crude kiss. Yuri wrapped his arms around his sister’s back, slapping his hands clear across her shapely ass, and kept them there as he continuously fondled them. This went on for a time, neither breaking away, until the need for oxygen came and the two had no choice but to do so. They both then pressed their foreheads onto each other, staring deep into their shared, crimson-colored eyes, and smiled.
“Yuri…”
“Yor…”
As another declaration of love was on the sibling’s tips of their tongues, black clouds of smoke floated onto their faces, making them cough excessively from the awful smelling fumes. Yor turned towards the stove and saw a raging fire bursting from where she had left the pancakes. “NOOOOOOOOOOOOOOOOOOOOO! MY PRECIOUS PANCAKES!” Yor screamed as she began using her apron to try to quell the flames, which unintentionally only managed to make them bigger. “YURI, HELP!”
“DON’T WORRY, SIS! I KNOW WHAT TO DO!”
“YURI, NO! DON’T USE YOUR HANDS! QUICK, GRAB THAT GLASS OF WATER AND THROW IT ON THE FIRE!”
“OKAY!”
And as he did just that, it only made the flames even bigger and spread across the stove and countertop.
“…That wasn’t water, was it?
Yor grabbed the glass, ignoring the flames, and tasted the remaining liquid inside. “…Oh, that was alcohol.”
“Oh…” Yuri nodded, also ignoring the flames that were slowly reaching the two. “…Should we run?”
“Yes, we should.” Yor nodded as well.
And that was how Yor burned down her first apartment (minus all the other times she had done so for assassination reasons) and was forced to move into her brother’s until she found a new place.
