Chapter 5: Of Oversights

After several hours of sexual discovery and more, Kate appeared on her own doorstep, she felt refreshed and thankful for the latest shower she’d had at Cane’s apartment before heading back. Her hair had dried nicely as it clung the small of her back the tips ending in richly coiled curls. Even her Mohawk looked surprisingly pleased with itself, as she eyed herself once more, eyeing each piece of her clothing one last time, starting from her combat boots that had seen better days, her black lace thong, her fishnet stockings that had held surprisingly well used, short leather skirt that had been ridden up so many times that it was a miracle it was still in one piece and her favourite studded bra with a broken strap that she had somehow managed to fix with a safety pin and her black t-shirt that had survived the night’s escapades.

Walking through the quiet space of the apartment to her room, Kate couldn’t help but feel a sense of power and liberation. The night had changed her, had unlocked something deep within her that she had never knew existed. The thought of Cane, his expert hands, his commanding voice and his giving heart and body had her clenching her thighs together as she felt a phantom touch of his fingers against her skin.

But her body was demanding rest; she thanked herself for doing this on one of her days off, with tomorrow to recover. Next time she would have to pace herself, despite the shower and its pleasant sauna effect her body ached like it wanted to set her on fire for the abuse she had put it through. Fair credit to Cane, he had warned her that hard won experience tended to leave marks so she wouldn’t forget. Luckily he hadn’t left a single one on her despite losing themselves more times than she dared to count.

Sliding gratefully on her bed, she undressed completely and lay on her stomach. She took her sleeping pill with grateful ease and slept a dreamless sleep. Perry on the other hand had different ideas, as he’d watched footage sent to him via private email with a specific timestamp highlighted in the message. As he sifted through he came to the recorded part about the incestuous roleplay and thanked God himself Cane was on his side, as much of a biblical contradiction as that sounded like, when he thought about it with a slight chuckle.

As Kate arrived home, he watched her slide naked onto her sizeable stomach on the bed and take her pills. He waited cautiously for an hour, slipping in through the crawlspace as silently as he could, his sister still having the presence of mind to lock the door behind her. He let his nightvision adjust, the curtains were already drawn, the window closed shut so he didn’t have to worry about that and having discovered her sister had taken birth control as well as morning after pills for contraception the last time she had been unknowingly been raped, he’d searched her room beforehand and found both long term stashes, replacing them with convincing placebos before she arrived back from Cane’s.

After she left the apartment on her day off tomorrow he’d replace them with the real things, although Cane had advised him he could have just as much fun with sister’s unsuspecting body without the intention of impregnating her. Regardless he’d given Perry his head, telling him he did have a plan in store which would in fact facilitate his impregnating his sister but that he should always have his own backup instead, as Cane put his own ego aside and added all plans were fallible, even his own.

Perry had respected what Cane had asked knowing that the manipulation had to be carefully managed, especially with someone as fiery and independent as Kate. He waited patiently as the hour passed, listening to the soft, even breaths that signalled her deep sleep. He had watched her with a mix of admiration and envy, the way she had taken control, the power she had wielded over Cane. It had been exhilarating, and he couldn’t wait to see how this would unfold.

Naked as the day he was born he slipped up behind her. Her legs were already spread out behind her as he approached with no fear, only exhilaration. He placed both hands first on her left thigh, bending the knee under her raising her left hip higher into position before he did the same with her right one. Her sister none the wiser in her pill induced unconscious state, as he slapped her asscheeks lightly, watching how they quivered like loose jelly. The split of her open pussy gleaming like an open invitation as he looked at his own swollen penis, deciding once and for all if he was gonna’ enter her raw and commit to impregnating his only sister or not.

With a grin that would have looked sinister regardless the context, Perry decided to go for it. He lined up his cock with Kate’s pussy, feeling the warmth of her body radiating up to meet him. With one swift motion, he slid into her, his eyes rolling back in his head at the feeling of her tightness enveloping him. She was wet from her earlier activities with Cane, which made it easier for him to push deeper, filling her completely.

Most probably there was still some of Cane’s leftover semen clinging to the walls of her womb, so to Perry’s reasoning any he added to it, would just seem like an oversight his sister could explain away as simple afteraffect of their earlier lovemaking. For now he focussed on his own pleasure, in his mind if he had regrets prior to climaxing in her he could always pull out.

Kate slept soundly, oblivious to the intrusion, her body still humming from the intense evening she’d shared with Cane. Perry’s cock slid in and out of her with ease, his movements careful not to disturb her slumber. He marvelled at the way she felt, the way her body responded to him despite being unconscious. It was as if she was made for this, for him, and he couldn’t help but feel a twisted sense of rightness, like he was meant to be doing this.

His own breathing grew ragged as he picked up the pace, his hands roaming over her curves, feeling every inch of her that he had dreamt of for so long. He knew he was taking a risk, but the thrill of the taboo act was too much to resist. His thoughts were a whirlwind of lust and power, his mind racing with the possibilities of what could come from this night.

His hips collided wildly with his sister’s huge ass from behind, as it rippled uncontrollably, her moans in sync with his deepening thrusts, his hands tightly squeezing her cheeks. The room was filled with the slap of skin on skin and the wet sound of his cock pumping in and out of her, mixing with her own juices. Her already taxed body quivering under the abuse, but his mind was set on his prize, he had to fill her up, mark her as his.

Her breathing grew more laboured, and her moans grew louder, even though she was still deeply asleep. The drug was working perfectly, allowing her body to react while keeping her mind blissfully unaware of the violation happening to her. He watched with satisfaction as her pussy began to tighten around him, her body gearing up for an orgasm that she would never remember.

Perry’s own climax was building, his cock pulsing inside her, as he felt the warmth of her body grip him tighter with each thrust. He knew he was close, and the thought of filling her with his cum, mixing with Cane’s, was almost too much to bear. He leaned down, whispering in her ear, “Cum for me, Kate,” his voice a twisted echo of the gentle encouragement Cane had given her earlier.

Her body responded, her hips bucking up to meet his, her pussy clenching around him. He could feel the orgasm building in her, even as she slept, her body an instrument of pleasure that he played like a maestro. With one final, powerful thrust, he released himself inside her, filling her with his seed. He watched with a sick fascination as her body responded, her muscles spasming around his cock, her juices mixing with his as she came with the equal amount of force, as when she was fully conscious, her body giving away what her mind couldn’t.

Sliding out of her, he stood back to admire his work. Kate’s body lay there, sprawled out on the bed, a picture of innocence despite the depraved act that had just occurred. He knew that when she woke up, she would have no memory of this, no clue that her own brother had claimed her in the darkest of ways, as milky strands of cum slowly slid out of her, onto the bed beneath her.

The only thing he didn’t expect was for her to move, as she slowly positioned herself on her back, saving him the arduous task and effort of moving such a tremendous weight. Her legs remained open, welcoming, and inviting as if she had been expecting him all along. He smirked to himself as he stepped closer, kneeling beside the bed. His cock was still rock hard, and the sight of his sister’s naked, vulnerable body only made him more eager to claim her again.

Once again he felt like a child in comparison to his sister’s girth, sinking his full bodyweight into her, his cock sliding along her thighs until it found her pussy, still pulsing and hungry for more. He pushed in, feeling the warmth and wetness of her juices mixing with his cum from moments before, creating a thick cocktail that he knew would be impossible to miss the next time she looked. He’d make sure to clean her up just enough so that she wouldn’t question it in the morning. As he sank his entire head into her pillow-like breast, he felt invincible, unstoppable and highly dangerous as the thrill of what he was doing powered his thrusts, feeling every part of her respond, as he let himself go.

Perry loved her breasts, huge but in proportion to her obese weight, as he sucked and stretched them with his mouth, his teeth grazed her hardened nipples that stood tall and proud even in her sleep. He watched her stomach jiggle with each thrust, mesmerizing like watching a bowl of gelatine wobble. The power he felt was overwhelming, his sister’s body was a playground and he was king. He knew this was wrong, but it was a wrong that felt so right.

He felt his climax approaching again, and he whispered “I’m going to fill you up sis,” his voice thick with lust. Kate’s body responded as if it had heard him, her hips rising to meet his, her pussy tightening around his cock. He could feel her pulsing around him, and it was all he could do to hold back his own release.

With one final, powerful thrust, Perry emptied himself into Kate, his cum spurting deep inside her. He watched as her stomach grew taut and then relaxed, taking in the evidence of his actions. He knew he had to be careful, he didn’t want to leave any evidence behind that could lead to questions, but the feeling of his cum mixing with her juices was too tempting to resist, letting it flow deep into her for now, as he parted her unresisting mouth with his tongue, kissing her like he always wanted to, feeling her own tongue respond, a reflex that had him smiling into the kiss, as she moaned into it, he couldn’t get enough, tangling his with hers longer, deeper, like he was claiming her from the inside out, as he began to swell deep inside her, his cock eager for another round.

Slipping out of her he knew just where to put it, as he raised her head with his hands to the tip of his penis, guiding it into her mouth, as he felt her instinctively suck on it, her eyes still closed, he smirked knowing the drug had made her a perfect plaything. He watched as her cheeks hollowed out with each suck, her eyes fluttered open briefly to reveal a glazed look, as if she was just waking from a deep sleep. But she didn’t push him away, she didn’t resist, she just kept sucking as if it was the most natural thing in the world for her to do.

No part of her resisted, as if her body was programmed to do exactly as he desired, even in her unconscious state. The thought was both terrifying and exhilarating to him. He watched as her plump lips formed a perfect “O” around his cock, her cheeks hollowing out with each bob of her head. It was like watching a porn star at work, except she was his sister, and she had no idea what was happening.

He stroked her hair gently, the silky strands sliding through his fingers as he lost himself in the sensation of her mouth on him. Her tongue swirled around his shaft, and he could feel the beginnings of another orgasm building. It was a heady feeling, this power over her, and he knew he had to be careful not to get carried away. But the temptation was too great, and he gave in, pushing her head down on him further, until he felt the tip of his cock touch the back of her throat.

It was truly a heady feeling, pardon the pun, as Perry’s cock slid into Kate’s mouth, her cheeks hollowing and filling as she sucked him off with the same enthusiasm she had for the ice cream she devoured as a child. He felt like a god, his sister’s body a mere vessel for his desires, her mind trapped in a chemically induced sleep that allowed him to play out his darkest fantasies without fear of repercussion. The power was intoxicating, and he knew he had to keep her under his control, to keep her coming back for more, to keep her his.

“Swallow everything when I cum”, he said, his voice a command that Kate’s sleep-addled mind couldn’t quite comprehend. Yet, as if under a spell her throat muscles tightened around his cock, preparing for the inevitable, as Perry’s grip on her hair tightened as he felt his climax approaching, his hips bucking wildly against her face. He watched with dark satisfaction as her eyes remained closed, her mouth working him with the same fierce hunger she had shown Cane earlier that night. It was a twisted mirror of their earlier scene, but the power dynamics had shifted dramatically.

He knew he was crossing a line, but the thrill of the taboo was too potent to resist. He could feel himself growing closer to the edge, his cock swelling with each suck and swirl of Kate’s skilled mouth. With one final grunt, he released his load into her mouth, watching as she took it all without protest, her throat working to swallow every drop. It was a sight that would be forever burned into his mind, a testament to the control he had over her.

As she sucked the last cloying strands from the head of his tender organ a thought struck him, maybe even the most important oversight in all this that even Cane hadn’t picked up on, as he slid out of her and took a step back off the bed, watching her for only a second before he said “Kate, I want you get off the bed and when I lay down on it, I want you to straddle me”, he instructed, not really believing it would work but taking a shot in the dark anyway.

Her response was sluggish under the sleeping pills effects as she stood up on the other side of her bed waiting for him to lie down before she could begin. His mind felt blown, he could now have it all, as he slowly got onto his sisters bed, lying down on his back.

The room was still, the only sound the faint rustle of fabric as Kate slid onto the bed, her body moving with the grace of a sleepwalker. She straddled him, her legs spread wide, and his cock stood erect, eager for the next round. He guided her hips, aligning her pussy with his cock, watching with anticipation as she sank down onto him, her body swallowing him whole.

“Now ride me, until we both cum. I want you to roleplay like you did with Cane, like you want to fuck and dominate your baby brother more than anything”, he said knowing it was the ultimate test and now his only fantasy. Kate’s eyes fluttered open, the glaze of the sleeping pill not quite letting her focus, but the command in his voice resonated through the fog in her mind. She began to rock her hips, her pussy enveloping him completely, her movements becoming slow and methodical as if her body was on autopilot.

She leaned in close whispering with a sultry yet dominating tone he had never heard her use except in the recorded videos with Cane “You want this, don’t you, baby brother?” she asked, her voice a siren’s song in the dark room. Perry’s heart raced, the reality of the situation setting in, as Kate began to move her hips in a slow, deliberate rhythm, grinding down on him, her pussy tight and wet, her massive breasts bouncing with each motion.

He nodded his voice a strangled moan as he watched his sister take charge of their twisted play. “Yes, Kate,” he murmured, his hands reaching up to cup her breasts, feeling the weight of them in his palms, his thumbs circling her erect nipples. “I want it all.”

Kate leaned in closer, her breath hot against his ear. “Then beg for it,” she purred, her hips never stopping their sensual dance. “Beg for your big sister’s pussy.”

Perry’s eyes widened, his body responding to the twisted role reversal. “Please, Kate,” he whispered, his voice shaking with a mix of fear and excitement. “Please ride me, make me feel good.”

“Harder”, she replied ‘beg me harder, make me believe this is all you ever wanted”, she said, her voice a seductive growl that sent shivers down his spine.

Perry swallowed hard, his heart racing as he felt the weight of the situation. “Kate, I need you,” he groaned, his voice thick with desire. “Please, let me feel your power, let me worship you.”

“Good answer”, was all she said before leaning down to kiss him, her tongue pushing past his teeth as her hips began to pick up speed. The drugs had her moving with a mechanical grace, her body a perfect instrument of pleasure for him to use, as he grabbed her ass and squeezed the inviting flesh, kneading it like dough as she began to bounce faster on his cock.

She was amazing, breathtaking, as she sat on top of him, her massive body moving in a way that could only be described as erotic poetry. The way her breasts swayed in rhythm with her hips, the way her stomach rolled like waves in the ocean with each bounce, the way her asscheeks slapped against his thighs in a tempo that was music to his ears. It was like watching a dream, except he was a part of it, and it was real.

He couldn’t believe neither of them had thought of this before with verbal commands. It was both so simple yet elegantly disguised in her sleeping, pill addled state.

Perry watched Kate’s large breasts sway as she rode him, his hands firmly planted on her wide hips to keep her steady as she bounced. The sensation was overwhelming, her warmth and wetness enveloping him completely, her weight pressing down on him, and he felt himself getting lost in the moment.

“Oh my God Kate, you’re so amazing”, he said wondering if she would respond as he felt himself getting closer to climax, her pussy tightening around him with every thrust, her moans grew louder and he could feel her walls pulsing as if she was trying to milk him dry. “I’m gonna cum again”, he warned her, his voice strained with pleasure.

“Do it”, she murmured, her voice a sleepy command that sent him over the edge. He felt his cock throb and swell, his cum spurting into her, filling her up once more. Kate’s body responded with another orgasm, her pussy clenching around him, her breath hitching in her throat, as she exploded over him in a torrent of lust and natural essence, the brunt of it hitting his stomach and hips, the rest coating him in a sticky sheen of their combined releases that filmed his upper thighs.

As Kate’s rhythm slowed down and eventually came to a halt, she leaned down again and whispered something else in his ear, something that made his heart skip a beat. “I want you to fill me up, baby brother,” she said, her voice still thick with sleep but the words clear and deliberate. “I want you to make me pregnant and I want it now”, she commanded as she changed positions, lying on her back, her massive thighs spread wide open. “Or I could get someone more worthy to do the job for you”, she added with a smirk, her voice carrying a hint of the Kate he knew was there, despite the haze of the pills.

Perry’s mind raced. He hadn’t expected this, but the thought of losing control over Kate’s body, the thought of someone else claiming her in the way he had just done, was suddenly unbearable. He quickly moved into position, his cock already beginning to harden again at the thought of what he was about to do. He slid into her with ease, feeling the warmth of their combined juices coating his length.

“Come on, show your sis you mean it, show me you want it more than Cane more than anyone else”, Kate coaxed like a siren luring a sailor to his doom, her voice a mix of sleepy drawl and seductive command. “Prove you can give as hard as you can get”, she commanded “or find me someone who can”, she taunted, her eyes still glazed over but her smile playful yet serious.

This pushed him over the edge, his desire to claim Kate fully igniting as he took her words as a challenge, thrusting deep into her one more time, his body moving with a newfound urgency. “You’re mine,” he growled, his hands gripping her hips tightly. “Only I get to fill you up, only I get to make you pregnant.”

“Maybe”, she said in a cooing, babying voice “if you have the stones”, she smiled hazily, her eyes still not focusing on him, yet her words were so clear it was like she was fully aware.

Her words fuelled his desire, and he began to pound into her with everything he had, his cock sliding in and out of her soaked pussy with a wet squelching sound that echoed through the room. He felt her walls tighten around him, her body begging for release, and he knew he had to give it to her.

With each thrust, he could feel himself getting closer to the edge, his balls tightening with the promise of another orgasm. He watched as Kate’s eyes fluttered open once more, a sly smile playing on her lips as she felt him growing inside her. “That’s it,” she murmured, her voice barely above a whisper. “Claim me.”

Perry’s grip on her hips tightened, his movements becoming more frantic as he approached climax. He knew he had to make this count, had to leave no doubt in Kate’s mind that she belonged to him. He thrust into her one final time, burying himself to the hilt before releasing his seed, feeling it fill her up with the same intensity as before.

Her body quivered beneath him, her eyes squeezing shut as she let out a guttural moan, her orgasm crashing over her like a wave. He watched in awe as she writhed in pleasure, her body taking everything he had to give. It was a powerful moment, one that cemented their twisted bond in a way nothing else could.

As Kate’s breathing slowed, Perry leaned down to kiss her, tasting the sweetness of their combined releases on her lips. He whispered “now I want you to act as you normally would if you found me using your sleeping pills as a way to fuck your unconscious body. I want you to resist but to be too weak to fight me off”, he instructed, enjoying the power play.

She responded almost instantly, her eyes snapping open and a look of shock and horror crossing her face. “Perry, what the fuck?” she slurred, trying to push him away, but her arms felt like lead weights, her body too weak to resist “it’s okay, Kate,” he whispered soothingly, pressing his hand against her chest to keep her in place. “It’s just us. I know you want this.” He could see the confusion in her eyes, the beginnings of understanding, and fear. But the drugs had her in their thrall, and she couldn’t do anything but lie there and take it.

Her feeble protests grew weaker as he continued to thrust into her, his body moving in a rhythm that was both familiar and alien. The weight of his chest pressing into her breasts, her soft moans muffled by his mouth as he kissed her deeply, her tongue sluggishly responding to his. He felt a twisted sense of triumph, knowing he had her exactly where he wanted her.

“I want you to get ontop of me Kate and ride your little brother until he cums inside of you again”, he said with a dark glint in his eyes. Kate’s drug-induced haze made her movements slow, but she complied, straddling him once more, her massive breasts hanging like ripe fruit, ready to be plucked. Her pussy was still wet and welcoming, the scent of their combined arousal heavy in the air.

The horror written on her face was a stark contrast to the way her body responded to his touch, her pussy still clenching around him, her hips moving in a slow, almost lazy, rhythm. It was a dance of power and submission, a ballet of manipulation and desire that played out in the dim light of Kate’s bedroom. Perry felt a twisted thrill at her compliance, his cock hardening even more as he watched her struggle to resist.

“Come here babe, let me feed off your nipples they’ll be lactating in a few months, so I’ll need to practice”, he teased cruelly, his words a mix of excitement and malice as he watched her confusion grow. Kate’s mind was racing, trying to piece together what was happening, but the pills held her in their grip, leaving her body open to his whims. “And don’t worry, It’ll be my baby you’ll be carrying, not Cane’s, he’s too sweet on you to ever do this”, he said as he sank his face into her swaying breast, burying it fully into her cleavage, as his hips continued to thrust simultaneously.

Her mind was foggy but the words stung, a spark of anger igniting in Kate’s chest. She knew she had to fight this, had to get away, but her body seemed to have a mind of its own. It was as if she was watching herself from a distance, unable to control the actions her body took. The idea of being used by her brother was too much to bear, but the pleasure was undeniable. The conflict raged within her, the haze of the drugs making it difficult to process the situation fully, as her hips slammed over and over again onto his waiting dick and her body catered to his every whim as if she were some cum hungry slut in a hypnotic thrall.

Her breasts swayed with motion, and she felt a strange sense of power in the way he worshipped them, his mouth moving from one to the other, his teeth grazing her sensitive nipples, sending shockwaves of pleasure straight to her clit. It was a perverse kind of power, one she never knew she could hold over someone, especially not her brother. But here she was, dominating him even in her compromised state.

Perry looked up at her, his eyes dark with lust and something else, something Kate couldn’t quite put her finger on. “Tell me how I’m making you feel Kate, tell me everything”, he demanded, his hands now reaching up to grip her breasts, his fingers digging into the soft flesh...

“I-I don’t know,” Kate murmured, her voice strained. She could feel the fog of the sleeping pills starting to lift, but the sensations of his cock inside her and his teeth on her nipples were too intense to ignore. “It feels good, but...”

Perry didn’t let her finish, instead, he took control of her body once more, his hands moving to her hips to guide her movements. “Just focus on the pleasure,” he said his voice low and soothing. “Let go of everything else.”

And Kate did. She closed her eyes and let her body take over, riding him with a newfound intensity, her walls clamping down around him, milking him for all he was worth. The feeling was indescribable, a mix of pleasure and pain that sent her spiralling closer to the edge. Her moans grew louder, filling the room with the sound of their incestuous union.

Perry watched her, his eyes dark with desire as he felt her pussy tighten around him. He knew he had her exactly where he wanted her, and the thought of her carrying his child only served to drive him deeper into her. “That’s it, Kate,” he murmured, his voice thick with lust. “Let’s make a baby.”

Her eyes snapped open at the mention of a baby, the reality of the situation crashing down on her like a ton of bricks. Despite the fog of the sleeping pills, she felt a surge of anger and disgust at the thought of her brother impregnating her. But the drug had its hold on her, and she couldn’t fight the pleasure that his words brought.

“Please, stop,” Kate managed to say, her voice barely above a whisper. But her body was betraying her, responding to his touch like it was programmed to do so. The anger grew within her, mixing with the arousal and creating a volatile cocktail of emotions.

Perry’s eyes narrowed, his smile turning predatory. “You’re mine, Kate,” he said, his grip on her hips tightening. “And I’ll do whatever I want with you.” He slammed into her one more time, her body jolting with the force of it.

Kate whimpered, trying to push him away, but her limbs felt like they were made of jelly. The anger grew, fuelling her need to fight back, but the pleasure was too intense, too all-consuming. Her pussy clenched around him, and she could feel another orgasm building. “No,” she whispered, tears pricking at the corners of her eyes.

Perry leaned up, grabbing her face with both hands, forcing her to look at him. “You love it,” he said, his voice a mix of challenge and triumph. “You love the way I make you feel.” He kissed her hard, his tongue invading her mouth as he continued to fuck her with a brutal rhythm that she couldn’t resist.

Kate’s eyes fluttered shut again, the pleasure overwhelming her. She didn’t want to admit it, but her body was responding to him, her orgasm building with every thrust. The fear and anger melded with the pleasure, creating a maelstrom of sensation that she couldn’t escape. She felt his cock swell inside her, and she knew he was close to cumming again.

“I’m going to cum inside you,” Perry growled, his hips bucking up to meet her every downward movement. “You’re going to take it all, Kate. You’re going to be mine.”
