Try to disobey and flee the scene

Dave stood there for a moment as he weighed his options. He could hear the sincerity in Rose's voice, and the certainty that her tone held as she spoke to him. He knew she wasn't lying and that was the worst part of the situation.

So he took his time and as he did he looked around the disgusting room. He saw her old clothes piled high in the corners of the room, and covered in stains. He saw jugs of soda now filled with a bright yellow liquid that he was pretty sure wasn't Mountain Dew. He saw all the signs of her filthy, disgusting, depraved lifestyle, and he cam to a decision.

"No, I'm not gonna fucking bow down before you. I don't care if mom says we're moving to the Fempire. I'm not gonna become the pet of my disgusting shut-in sister. So I'm not gonna kiss your filthy pussy, and I'm not gonna follow any of your stupid orders. If that means I have to find my own place to live then I'll speak with mom and figure out something on my own."

Dave spoke up as his voice grew louder and louder with each word. His anger at the situation bubbling over. His body turning around as he prepared to leave. His body seething with anger at the whole situation.

As he turned to leave he didn't hear her sigh out dejectedly, or the sound of her grabbing something off her table that was buried beneath piles of old cup noodles. What he did notice was the stinging sensation in his shoulder as his body went rigid and then limp. He could feel something imbedded in his arm as if he was shot, but as he fell to the ground he felt his consciousness begin to grow dark and fade. He found himself face down on her filthy stained carpet as he heard her speaking while standing over him.

"You just had to act like a defiant little toy didn't you. It's a good thing moms been showing me some of the Femcorp products she's been working on like this Boy catcher, but now I'm gonna have to punish you for being so rebellious."

Those were the last things he heard as he saw her feet walk up to him and his vision finally went dark.

*****************************************************************

Slowly Dave's mind returned from the darkness that had consumed it. Like a train coming out of a tunnel his consciousness slowly came back. He could suddenly feel the cold air biting at his skin and a weight on his chest. His arms and legs still felt like rocks at his sides, but carefully he opened his eyes once more.

The first thing he noticed is that he had been stripped sometime in his unconscious state. His skin was now bare as he laid there on the floor. Still in Rose's room but clearly having been moved during the process. He looked around and immediately saw Rose, half naked as well as she had her bare feet pushing down on his stomach. She sat beside him as she looked him over and kept him pinned with her legs. Not that he was in a state to move at the moment anyways.

"Well well, looks like you finally decided to wake up. Don't worry it hasn't been to long, and I haven't done anything to you yet. So how do you feel about me now?"

She asked the question as she showed her clear dominance over him. Her sweaty feet pushing into his stomach. Dave tried to open his mouth to speak. Wanting to curse her out, but his mouth didn't want to respond to him. His tongue was like lead. So instead he just stared her down with a hard glare.

"HMMmm, seems like you haven't reconciled your actions. Well no hair off me I'll just punish you like I had planned. Don't say I didn't give you an out."

She said this as she moved her foot down along his body. He could her sweaty sole brushing against his skin as she moved her legs lower and lower. Finally her foot arrived at its destination. Resting against the base of his dick that was semihard in what he hoped was a state of morning wood. She pressed her soles against his dick as she spoke up.

"Y'know you got a pretty nice cock here. It'd be gross to say that if you were still my brother, but since you're my slave now it's just gonna be my nice little meat dildo. Though I suppose that's beside the point as I do still have to give you your punishment before we can train you with the rewards."

As she said that she flexed her foot back before kicking him across his dick. Pain radiated through his numb body as he felt a flashbang of pain coming from his crotch. He was lucky she had just hit his dick, but the pain still pulsed in agony.

While he was stun locked by the agony shooting up through his body he didn't even notice as she got up and started to move towards him. His first senses returning as he saw a shadow looming over him. Her sweaty bare ass was hovering over him. The raw aura of her stick descending on him in waves. The stink so much worse than what he'd been smelling earlier.

"Alright bro, time for you to get acquainted with my ass."

She said as she lowered her bare bottom onto his head. Using his face as a seat cushion for her damp sweaty ass. She was not gentle either as she crashed into him with the force of someone landing on a chair and not a person.

Dave found himself engulfed by her sweaty greasy skin as it rubbed against him and bared down on him.

The foul stench quickly filled his senses and overwhelmed the feelings of pain he had from her force. His skin tingled as it came into contact with her disgusting sweaty slime. The soft squish of her cheeks barely registering in his mind as all signs of light disappeared.

She began to scoot her ass back and forth across his face. Rubbing her filth and stink into his pores. Meanwhile her objective was trying to line up her brown starred anus with his nose and mouth. He kept his lips sealed but he could feel her dark aura trying to reach him. Her odor invading the nose he couldn’t block and bringing tears to his eyes.

“Alright bitch boy. Open wide and start licking my shit hole clean. Otherwise I’m gonna keep kicking your dick until you learn how to treat me right.”

Her voice was mocking as she continued to grind down on him. With a shudder of hesitation he opened up his mouth and the foul air flowed into his body. A slight stinging sensation reverberated from his lungs as they came into contact with the foul air.

He wanted to take a moment to pause, but his dick was already throbbing in pain from the earlier kick. So with his body telling him not to he extended his tongue and began to lick at her cheeks in front of him. Her grease coming off in layers that filled his mouth with a taste worse than dirt. His mouth could only detect the flavor of her unwashed ass. Sweat, shit, And so much else covering his tongue.

He wanted to retch and gag but even pausing for a moment he felt her resting her sweaty foot on his cock as a warning. So he continued to lick away at her slimy asshole. The unwashed taste of her grime and body filling his mouth. His mind tried to blank out the sensations but the foulness overwhelmed him.

Almost as bad as the taste of her ass was the smell that was trapped around him. Her greasy unwashed stench mixed with the stink coming from her ass made a foul cocktail. What was worse was that he could feel her slick cunt dripping onto his chest as he continued his reluctant work.

"Mmmmm, You're working your tongue pretty well back there. Getting my shit hole all lubed up with your spit. With how well you're doing back there I'd almost believe you're enjoying yourself." She said as she let out a low laugh.

"Hhahaha. Though that's hardly the case yet. I have heard of a way to make sure you start to enjoy your new job as my ass worshipping stink slave. So lets start your training process." She said as she rested her filthy slimy foot and sock against his cock. Her foot squelching against the base of his dick, and as she felt his tongue entering her asshole once more, she started to slowly stroke her foot up and down.

A shiver ran through her body as she felt her insides being explored by his tongue. She then transferred her pleasure through her feet as she slowly began to stoke him off. Little by little against his will Dave's dick began to erect under the slow pressure of the foot job. His mind on blast between the foul ass above him and the soothing foot job pleasuring his lower head.

He tried to fight against it but her feet felt so soft and smooth against his dick. Her foot job being one of the few moments of peace he felt as her stank ass bore down upon him. He was desperate enough that he gave into her foul torture and continued his task. Taking the brief feeling of pleasure over the impending pain he'd felt before.

"MMmmmm, You're being such a good little pet down there. Do you like the feeling of my sweaty stinky feet? Do you get hard to your little sister rubbing her sweaty socks on your dick? Do you like licking away at my smelly asshole?"

Her questions were rhetorical as she rubbed her ass over his head once more. She felt his dick throbbing from her foot job. The dick being fully erect and standing up as her feet played with it.

"Ok looks like you're being a real good boy. Time for the next part of your training. You're probably not gonna like this bit, but it should be part of you're new duties. So do well and I'll make sure you feel nice afterwards"

She said this as she pushed her ass down on him harder. Completely smothering him and locking him away under her soft flesh. Her body began to shake and a great rumbling passed through her. Dave could feel her shivering in anticipation and came to the realization of what was about to happen too late.

PHHGHSHHAAATTTT

Her ass blasted him in the face with her rancid fart. The smell of sulfur flooded into his nose and mouth and the hot air blew past his skin. Just the feeling of the gas felt like a cloud of acid on his face. The strong stench was like nothing he'd felt before as it choked him out. His lungs were burning as all semblance of clean air was removed from the environment.

He tried to hold his breath but after a few moments he couldn't take the burning in his lungs and reluctantly took a breath of the noxious fumes. While he was suffering under her gas his dick was being mercilessly stroked and played with leaving his body completely confused.

"Wow, that was a really wet one. I'm glad it didn't come out solid. Now suck up all my gas, I don't want to smell a whiff of my farts. Or else this pleasure is gonna turn into pain for your dick."

She said this in her usual mocking tone, and not wanting to fight any longer Dave eventually relented and continued his previously given task of worshipping her ass.

His eyes stung and watered from the foul stench that clung to him. Tears streaked down his face and his body ached in pain. Fearing the pain however he continued on. His mouth open as he inhaled her ass gas and continued to worship her ass.

He did this in an almost dazed state as he tried to separate his mind form his body. He focused only on the slight pleasure his dick was receiving and not on what his upper body was up to. It was the only way he was able to stay semi sane in the putrid hellhole he'd been thrown into.

He focused all his will onto his dick as he felt it twitching and throbbing under her pleasure. He felt every bit of her damp feet as they rubbed up and down on the shaft. Her toes lightly gripping and playing with the tip. Focusing all his will on the pleasure magnified it and slowly he felt the pleasure building up deep inside of him. From there it was only a few short moments before his shameful orgasm occured.

His dick throbbed and spasmed briefly before a wave of warm cum blasted out of it. The cum shot out and covered Rosa's feet in the thick gooey substance. It was the biggest shot that Dave had ever created as her feet and legs were covered in the thick substance. His already weak body felt exhausted after the shot. Meanwhile Rosa just stared in shock as the cream ran down her feet. It felt oddly satisfying to her to have him orgasm to her feet and ass.

"Wow, looks like you're really enjoying yourself down there. How does it feel knowing you just got off to you little sisters ass and feet? Do you like my feet on your pathetic little dick? Is my smelly ass so alluring that you just can't help yourself?"

He was stunned by the situation as his body felt the afterglow of the orgasm. His mind not even processing what Rose was saying above him. His body going limp as he rested in the swampy area he was trapped in. The remaining cum slowly oozing out of his dick and pooling on his stomach.

“Alright big boy. You’ve been doing well so far. I guess I can change your training to be a bit more rewarding. Plus seeing you blow your load like that has really woken something up in me.”

Rose said this as she leaned forward. Her ass lifting slightly off of his face as he felt his first breath of fresh air hitting him. She leaned forward until his dick was right in front of her face. Taking in a deep breath of his dicks smell before sticking out her tongue and taking a taste of his cum for herself.

Dave moaned again as his still sensitive cock was stimulated by her tongue running up and down its length. She tasted his dick as she took in the musky flavor of his cum and the sour taste of her foot sweat coating the length. She reveled in the strange taste as it filled her mouth. She leaned in even deeper and began to suck on the tip of the cock. Taking more and more of the cock. Running her tongue up and down and into all the crevices as she absorbed the flavor. Finally she pulled back after sucking the cock clean of cum. A trail of saliva connecting her mouth to the dick.

“Mmmmm, not a bad flavor boy toy. I hope you liked that part because I have some more fun stuff planned for us.”

She said that as she rubbed her hands over the sensitive dick. It slowly rises back up to semi erection under her playful touch. Dave shivered at all the little touches as he felt all of his pleasure growing once more. His mind utterly shattered by the constant back and forth of filth and pleasure.

She slowly rolled her body off of him. Finally freeing him from being under her sweaty ass. Her pussy being noticeably moist and glistening as she felt her own sexual excitements.

She shook her hips above his face and showed off her horny pussy as she got off him. Her body teasing him with the stunning visuals of her aching crotch. While his dick was hardening once more under her playful fingers as they drew him back to full erection.

With her body off of him he could feel some of his strength returning. The effects of the stunner seemed to have somewhat worn off as he could now feel his body more acutely the weight that had rested on top of him was removed. He knew that if he really struggled he could probably escape, but he also knew that she was still stronger then him in his current state, and she held his manhood in her grasp.

So when she swung around and planted her sweaty feet and damp socks right in his face he didn't resist. He was suddenly plunged back into a new smelly world as the stink of her feet rose up to meet him.

"Alright big bro, one last test for you. If you pass I'll give you your real reward and you will fully become my little play thing." She said this in a more sultry voice as she lorded over him. He could see her reaching up and grabbing a strange metal rod off her computer desk.

"Fail me and we'll have to do even more punishments and training. Now it seems you've dirtied my feet with your filthy cum. Lick them clean for me pet." She continued her verbal tirade as she lifted her feet up and showed the drops of cum clinging to the fabric of her socks.

Dave feared answering her as he saw the intimidating rod in her hands. He knew that if he tried to defy her now that he'd be in a world of pain. Seeing his silence as agreement she moved and smooshed her feet right into his face. The sweaty damp cloth smearing a line of sweat on his face. With a heavy feeling in his heart Dave gave in. He knew he couldn't show much more reluctance as he stuck out his tongue and it grazed against the damp fabric.

As his tongue made contact with the fabric his tastebuds were once more assaulted by the foul flavor of her sweat and filth. This one lacked the overpowering taste of filth that her asshole had, but instead was a more salty, almost gamey flavor of her foot sweat soaked into the fabric of her socks and marinated in it.

His nose was attacked by the cheesy smell of her foot odor as he tried to push back the tears and stinging in his eyes. He tried to only breath in through his mouth in an attempt to filter out the retched stench. Of course that only made his lungs and tastebuds burn even more as her smell invaded his body.

He couldn't take too much of this so instead he focused on the task ahead of him. He had been ordered to clean the cum out of her socks. So with a goal in mind he moved forward and found the drops of cum staining the already dirty socks. His tongue moving towards the splash even if he'd never imagined eating his own cum. Of course he had never imagined most of the things he'd been made to do today.

He licked up the first dollop of cum from her sock and felt it resting on his tongue. The taste of his own cum flooding his mouth with a salty and creamy taste that wasn't what he had expected. It certainly wasn't good, but it was nowhere near as bad as he'd imagined. It was almost a breath of fresh air compared to the taste already covering his mouth.

He tried to make quick work of the rest of the cum. He really didn't want to be doing this any longer than he had to. So doing his best to ignore the foul tastes and scents around him he quickly found each droplet of cum that had splashed onto her feet and licked it up. It carried with it the sour taste of her dirty socks, but was still better than being smothered under her filthy asshole.

When he finished he finally looked up and saw Rose gazing down on him with a smug look of Triumph plastered on her face.

"Alright, good boy. Looks like you've done all the tasks that little sis has assigned for you. So it's time for both of us to get our rewards. Ya see, I'm gonna take this big ol meat dildo for a real test drive. Give us both a shot of pleasure."

She said teasingly as she once more moved her body. Swinging her legs and hips around until she was sitting on his stomach. Her legs and bare bottom straddling his midsection. Dave could only look on in horror and arousement as she leaned in into him and slid her ass backwards until it was touching his dick. She just grinned back playfully as she had this lustful horny look in her eyes.

Finally she was laying on top of him. Her hot skin touching his as his dick twitched from all the constant play. With so much of their skin touching it sent ripples of arousal through both of them. Rose was slowly giving into the raw feelings while Dave just shut his eyes and tried to turn off his horny thoughts.

He tried to flood his thoughts of their childhood together and other reminders that it was his sister that was laying on top of him. Unfortunately his body wasn't listening as he could feel heat rising in his core. His body wanted this, it wanted to reproduce, and his will was finally broken when he felt her hot slick ass jiggling against his dick as she playfully teased him.

She took her hands and grabbed his dick. Rubbing his erection across her soft jiggling ass so that he could feel how soft and plush she was. She ran his dick along her slit and the warm wet entrance felt so inviting to him as it called for his dick to enter. His cock was throbbing and pulsing with each movement as she continued to tease and play with him.

"Alright, looks like we're about ready to start, but however should we do this." She said sarcastically as she lifted herself off of him. She positioned herself to be right over his dick as though she could just drop down and swallow it with her insides. "Here we go."

Her last words echoed out as she slammed herself down. Her body opening up and swallowing him whole. His dick being buried deep inside of her with one simple movement. However she hadn't taken him into her pussy. Instead as she'd dropped down she'd slid forward just a smidge, taking his dick into her asshole.

"AHHHhhhhhh"

They both moaned out together as their bodies connected. Their screams of pleasure mixing together into a strange symphony. Their bodies no connected by a single point as they both lost their virginities together. The sudden feeling of heat and pleasure flowing through them both as if building up in their cores for a while. The only reason they didn't both immediately orgasm was the play the two had already been doing.

With their bodies connected both lay there perfectly still for a moment as the feelings of lust burned their ways through their bodies. Finally Rose lifted her hips slightly letting the cock exit her warm asshole before pushing and dropping back down. Shoving the dick even deeper inside as she let out another small breathy moan.

Dave was shocked as the warm feeling around his dick. The feeling like a tight moist gripped hug just for his cock as her warm insides coiled around him. His body started to move on autopilot and as Rose lifted herself once more Dave thrust his pelvis forward. His dick sliding even further inside herself.

Rose Meanwhile was shocked at the feeling of having a cock in her ass. She'd played with a dildo plenty of times before, but the feeling of warmth that spread out from his cock was something she hadn't expected. She also wasn't prepared for the pulse and throbbing coming off him as it stretched herself out even further. Having his burning hot cock inside her felt like she was taking a massive satisfying dump.

It was a strange form of pleasure, but at the same time her body was craving the touch sensation. Her pussy was tingling and she could feel the build up of pressure. She could herself building up to a massive orgasm like nothing she'd ever felt before. She now had the perfect little dildo pet and she was gonna use it.

With that their movements picked up as the both started to bounce and thrust into each other. Their bodies craving the pleasure as they picked up the pace and started to slam into each other. They both felt the rising pressure and the build up to their own respective orgasms. They stared at each other with wild looks on their faces. The only sound being the rhythmic slapping of their flesh against each other.

CLAP CLAP CLAP

"Uh, C'mon and fill up my tight little asshole with your cum bro. Give me a shot of your juice and prove to me that your my good little pet. If you do maybe next time you'll get to feel my pussy gripping you instead."

She said as her voice was breathy and winded. He could immediately tell that she was getting tire, not normally used to this level of physical exhaustion. But still she continued to slam her hips into as she tried to milk his dick into her waiting asshole.

Dave wanted to hold out but his body wouldn't obey him anymore. He was moving on its own as it smashed deeper and deeper into her warm tight embrace. He could feel the pressure building up and he tried to mentally hold back, but thrust by thrust cracks began to form in his mental dam.

After several minutes of exhausting riding Rose felt a shudder go through her body before her body shook violently. The biggest orgasm she had ever experienced was wracking its way through her body. Her body convulsed and her pussy opened up before unleashing a spray of her juices. Most of it splashed harmlessly on his chest, but a few drops of the sweet nectar landed on his lips.

"OOOOOOAAAAAAHHHH"

She let out a loud moan followed moments later by a moan of his own. With her body shaking and convulsing Dave felt her asshole grip onto his dick even harder. It was so stimulating that he could no longer hold back and the dam over his own orgasm broke.

His body shook one time before he felt the sensation of cum rising up his cock like hot magma. He felt the sensation of his cum being pulled upwards into her ass as he unleashed a spray of hot semen inside her. His dick pumping more and more of the juice as his voice mixed with hers.

With this happening something in his mind broke, and Dave realized that there was no more going back. He was now his sisters slave and plaything, and this was now going to be the rest of his life.

As their orgasms finished they collapsed into one another. Rose lying limp across Dave's chest as she drifted off to sleep. His softening dick still inside her and keeping the warm cum trapped in her ass. She was beyond exhausted and all that was left was to drift off to sleep.

Dave felt somewhat similarly. He could finally feel his entire body once more. The stun effect having ended somewhere in the midst of their rutting. However now his body was too tired, sore, and exhausted to move. His entire body felt tinges of light pain and all he could do was lie there. So he did the only thing he could do. Take some solace in her warm sleeping body on top of him and drift off to sleep himself.
