Warning: Incest and Scat

---

It was raining out, and after the briefest of glimpses at the murky gray sky through the window, Jack decided that he wouldn't be leaving his room until his class that afternoon. He'd not yet been at college long enough for the novelty of laziness to wear off, and besides, he always woke with a painfully stiff cock, and there was no way he was heading to the co-ed bathroom with that poking out of his shorts.

He opened his phone, and began browsing for some viewing material that might help satisfy his morning urge. He was half-asleep still, and as he scrolled through the endless list of thumbnails, one caught his eye. It was a perfectly round, creamy white ass -- smooth and unblemished, reminiscent of a Renaissance painting, cheeks slightly spread to afford a tiny glimpse of a tight pink pussy.

He clicked it, and the picture came to life; that gorgeous ass bouncing up and down as its owner twerked, her ponytail bouncing along with it. As her cheeks moved, they spread ever so slightly, giving him flashes of her pussy and asshole, making his cock throb. He began massaging his cock as he watched, imagining that round ass pressed against his face, tasting the wetness of her pussy, breathing in her natural scent as he probed her holes with his tongue...

Jack could feel himself building to orgasm watching the ass clap on his screen. Two pale white, perfectly manicured hands reached around those beautifully smooth cheeks and pulled them apart, proudly displaying every inch of herself to the camera. Her asshole puckered once, twice, and then blasted a huge, long fart that rang loudly out of his phone's speaker. Cum exploded from his cock, his head flew back onto his pillow as he bit his lip with the force of it. It splattered all over his bare chest, and as he lay there, breathing heavily, gently pumping his cock for the last ounces of pleasure , he was vaguely aware that he could still hear farts through his phone speaker.

The headiness of his powerful orgasm began to wear off, and he reached for his phone to stop the video, on which the girl was still twerking, letting rip as her cheeks clapped. As he picked it up, though, he froze. On screen, shaking her ass, squeezing out violent farts and winking at the camera, was his sister. Despite his shock, his dick was already twitching again in excitement.

Sadie had always been beautiful. Growing up, they'd been as close as siblings could be; being only a year apart in age meant that they had always been best friends, and while Jack knew that his sister was attractive, he'd never been attracted to her.

As they'd gotten older, Sadie had undoubtedly begun to cut more of a womanly figure. With a naturally skinny waist and large hips, Sadie had the sort of hourglass figure that made all the girls jealous and all the boys crazy, and her shapely ass had always been the focus of Jack's friends' attention.

While her body might have changed, her face hadn't. Sadie still had the same huge, dark eyes that she'd always had, and her long, brown hair was always beautifully straight and meticulously brushed. Even knowing that everyone around him considered Sadie to be the sexiest girl in school, Jack had always seen her as his innocent sister, and never anything more.

That day in his dorm room, though, had been the beginning of Jack's biggest fetish - and also the beginning of his attraction to Sadie.

He'd missed her a lot when she'd left to go to college, and he felt a little lost at home without her. That last year at home for him, he'd looked forward to her visits, and now he couldn't wait to go home for the holidays to see her -- except after encountering her videos online, he found himself looking forward to it for all the wrong reasons.

Living alongside her again wasn't easy. Jack constantly caught himself staring at her ass, fantasizing about what she did when she was alone in her room, sniffing the air around her, and every time he'd have to excuse himself due to his growing erection, head to his room and watch one of her videos. It was awkward for him, but she seemed none the wiser.

That was, she did -- right up until she caught him. That morning, they'd been watching TV, and Sadie had let out a huge fart on the other side of the living room. Feeling his cock twinge with excitement, he'd had to quietly excuse himself. Not ten minutes later he was sat on his bed, his laptop next to him playing one of her videos, with his cock in his hand. Thinking she was safely downstairs, he'd not bothered to lock his bedroom door, and Sadie had burst in to ask him if he wanted to play video games. Seeing what he was doing -- and, more importantly, what was on his screen -- she turned bright red and ran out of the room.

After a couple of quiet, painfully awkward days of avoiding one another, Sadie had knocked at his door. She told him that she didn't want them to feel awkward around one another and had an idea for how to resolve the problem. When Jack hadn't known what to say, she told him that their parents were going out at the weekend, and they'd be able to continue the conversation properly then.

~

"So," Sadie said as the pair watched their parents pull out of the driveway, "you ready to talk about it?"

Jack blushed, still mortified that his sister had caught him masturbating over her videos, still painfully aware that the girl he grew up with had now seen his dick, in all its glory, rock-hard for her. "I guess," he replied.

Collapsing onto the sofa, Sadie began chewing her nails, as she always had when she was nervous.

"I started making videos just after I went to college," she blurted out. "A girl I knew was doing it, and she was making heaps of cash from horny dudes on the internet, so I figured I'd earn some spending money, you know?" She looked at him anxiously.

Jack, lost for words, just nodded his understanding. Sadie relaxed a little.

"Anyway, I did a couple, and this guy got in touch and asked me for a custom video. I figured he'd just want me to say his name a couple of times, maybe flash my feet or something, but he asked if I could fart into the camera for him." She was staring off into space, absently poking at a hole in her jeans. "I thought it was weird, but he was offering like a crazy amount of cash just for, like, a minute-long video. I thought 'why not, easy money', right?"

"Right," Jack said carefully. He didn't want to give anything away -- he was still a little ashamed that he'd developed the fetish at all.

"Well, I really liked it. The thought of farting on a guy's face, of him being desperate for my bodily functions, it's kinda... hot. Y'know?" She looked him dead in the eye, and he realized that she was asking more than just the question she'd spoken out loud.

"Yeah, I get you," Jack said, not daring to meet her gaze.

"Jack," Sadie said, "look at me. I'm your sister. Your best friend. Please don't judge me."

At this, Jack looked up at his sister, and all of his embarrassment began melting away. She really was attractive, he thought, as her big, puppy-dog eyes lured him into a false sense of security. He knew he was treading on thin ice.

"I get it," Jack replied. "I'd never thought about it before, either." Sadie looked at him, raising one eyebrow slightly. "Or you," he added hastily.

Sadie laughed. "But you think about it now?" she asked, grinning.

Jack couldn't stop himself from blushing, and he looked away as Sadie giggled.

"You might not want to answer, but that big bulge in your pants is telling me all I need to know," she said.

Jack looked at her, his discomfort plain in his eyes. "Sadie.. I-- We..."

"Shh," Sadie said, standing. "Follow me."

Jack followed her upstairs to her room. She gestured to the bed, and he perched awkwardly on the edge. Sadie rolled her eyes.

"Lay down," she said. "I think it's time you learned to give in to your instincts." She reached under the bed, producing four short lengths of dark rope. "Don't ask," she said.

Jack said nothing as she began tying his wrists to the bed posts, but his dick continued to grow in his shorts. As she finished with his wrists, Sadie noticed his excitement. "I'm going to do your ankles, too, okay?" she asked, although she didn't wait for a reply. As unsure as he was, Jack was too turned on to fight it, and let her tie his ankles down, too.

When she was done, she told him she'd be right back, and disappeared from the room. He was so nervous; it felt so *wrong*, but he couldn't deny the painful throb of his cock in his shorts as he began to think of exactly what she might do to him. The thought of his sister's ass, and of finally smelling the farts he'd been fantasizing about for months, steeled him against his own internal apprehension. He longed to grab his dick to massage away some of the building tension, but Sadie had tied him up pretty tight. His stomach lurched as he heard the door to her room, and in a brief moment of panic he imagined his parents had come home early, walking into Sadie's room to see him tied to the bed, his hard cock standing proud in his shorts, and he'd be unable to move as they looked at him in horror, unable to explain why he was there...

"Comfortable there, Jack?" Sadie said from the doorway.

He craned his head to see her, and watched as she closed the door. "Not really," he said. "My dick is throbbing."

"You'll live," she said, crossing the room. "After all, you beat off enough. Don't forget, we share a wall. I hear you hammering away at it night and day -- your headboard bounces off the wall." Looking down at him from her bedside, she smirked. She was dressed as though she was heading to the beach -- a pair of shorts that showed off the entire length of her legs, and a little of her ass for good measure, and a tight tank top that accentuated the fullness of her breasts, see-through enough for Jack to note she was wearing a pink bra.

"You like my outfit?" she asked as he gaped, finally allowing himself to study her body properly. "I know, it's a little tight. I grew out of these shorts years ago, but I wanted to make sure you got the full experience."

Jack nodded nervously, and she giggled. She laid a hand on his thigh, and his cock twitched painfully at her touch.

"Just going to make myself comfortable," Sadie said with a wink, gently squeezing his thigh. She climbed slowly onto the bed next to Jack, carefully and gracefully placing her knees either side of him. Painfully aware of how close his sister is to him, his cock fights against the fabric of his shorts, poking hard into the soft of Sadie's belly. She giggled. "Steady," she said, "we've not even started yet."

She wriggled herself back, using her ass to force Jack to lay flat. For the briefest of moments he felt her weight on his face, smelled the musky aroma of her through the seat of her shorts, and then she leaned forward, allowing him room to breathe.

"Ready?" she asked, gently shaking her butt just inches from his face. He nodded, and she edged even closer. He could feel the excitement building in him, battling with his nerves, and his cock strained harder against his shorts, stretching them tighter across his thighs.

He felt Sadie's body tense ever so slightly, then relax as a huge fart blasted from inside her shorts. It sounded exactly as it had in her videos, except this time it was real, warm and close, and he could practically taste it as it tickled his tongue. Unthinking, he recoiled, straining against the ropes at his wrists and ankles, but his cock twitched in approval. Sadie giggled on top of him, lowered her butt even closer to his face, hovering just above him, and ripped another.

"Sniff it," she said, stifling another laugh. "It's good, isn't it?"

Jack tried, but he gagged before he could breathe in, causing him to struggle even harder against his bindings. There was a part of him wishing that he hadn't gone along with it; but that part apparently had no control of his cock, because he was harder than he'd ever been in his life.

In response to his struggles, Sadie simply sat back onto her brother's face, cutting off his supply of fresh oxygen, wiggling her hips around. This close, the aroma of her farts mingled with that of her sweet pussy, and he could feel his throat attempting to retch against the lack of air.

After an eternity, Sadie lifted herself off of his face, just far enough that he could breathe. Expecting fresh air, Jack was disappointed by the slightly stale aroma of Sadie's lingering farts, but he gulped in mouthfuls regardless, her stench filling his aching lungs.

"Sniff it properly, this time, okay?" she said, her tone suddenly less playful. She let another one go, and Jack breathed it in as deeply as he could. As soon as it hit his throat, though, he gagged again, his retching causing the rope to cut painfully into his wrists. He felt certain that he was developing rope burn, and made a mental note to move as little as possible. She'd probably suffocate him if he struggled too much, anyway.

"That was much better!" Sadie exclaimed excitedly. Lifting herself a little, she slid her shorts down, and Jack was face to face with a pair of pink panties he'd only ever seen coming out of the dryer. She resumed her perch slightly lower on his face, putting her weight onto his closed mouth, neatly lining up her asshole with his nostrils. He gulped, having forgotten that the taste of her farts was still in his mouth, and gagged slightly. She giggled again. "I know you're enjoying it. You'll stop gagging soon, I'm sure."

She let out a couple of small, airy farts that went straight up his nostrils, and Jack didn't mind these as much. They still stank, but they weren't as overpowering as the last few, and he wondered if maybe she was right; maybe he was getting used to it. His cock was throbbing so hard that it shifted in his shorts, much to Sadie's delight. "I love the way your cock's ahead of your brain," she said playfully. "The rest of your body might fight against it, but your cock loves my farts!"

She let out another small puff of air, as though to prove her point, and Jack groaned from the pressure of his shorts against his cock -- which had apparently started leaking slightly, as he felt a little sticky. His head spun with the stench of the room, and his stomach was threatening to revolt, but his cock really was loving it.

"I think it's time to show you what you've been wanking over," Sadie said, looking over her shoulder at her brother with a grin. She reached back and pulled her panties down slightly, wriggling her hips to get them down. Her cheeks gently brushed his face as she did so, and a fresh wave of odors washed over him, causing his throat to convulse. His excitement allowed him to stifle his gag reflex. The fabric of her panties was tight against her juicy ass, and her cheeks jiggled delicately as she maneuvered her way out of them. Once they were down, she pulled at the waistband of his shorts, freeing his aching cock. She grabbed ahold of it, and it threatened to erupt, so intense was the relief of its freedom. Only the lingering stink in the room held Jack back.

"You like the view back there?" Sadie asked, wiggling her hips a little to highlight her point. Jack was no more than two inches away from his sister's wet pussy, but he couldn't take his eyes off her gorgeously puckered butthole. As much as he knew that he'd likely be subjected to more of her horrific farts, he was mesmerized by the hole before him, and he knew he wouldn't fight her on whatever she wanted to do.

"I'll take that as a yes," Sadie said, gently twerking, teasing Jack. His eyes followed her ass as it moved, and his head nodded ever so slightly as he did so. Gripping his cock tighter, she suddenly stopped. "Tell me you like it," she said.

"I like it," Jack replied mindlessly, staring intently at his sister's holes.

"You want to eat my ass, don't you?" she asked, spreading her cheeks wide, winking her hole at him, threatening to let out another fart.

Jack nodded rapidly, rendered dumb by the persistent throbbing of his cock.

"You will," Sadie said, looking back at him with a grin. "Not yet, though." She winked mischievously.

As Jack strained his neck to see if he could get closer, Sadie's stomach let out a quiet gurgle. She looked into his eyes, and raised her eyebrows. "Uh oh." She giggled, and moved her ass closer to his face, hovering just out of reach, spreading her cheeks as wide as she could.

She let out a massive, loud, rasping fart, one that smelled as though she'd been stewing it for some time, and Jack felt his cock twitch. Sadie giggled and ran her finger along the length of his shaft as she forced out another hot blast of gas, this time into his open mouth. Jack felt the hot air hit his throat, tasted the aroma of her dirty ass, but he didn't gag. His cock stood up even straighter, and Sadie grabbed hold of it.

"I knew you'd love it, you filthy fuck," she said, giggling. "It stinks so bad in here, I bet you'll taste it for days."

She let out another, this time smaller, and Jack found himself licking the air, hoping for a taste. He retched slightly as the rancid flavor hit his tongue, but his cock throbbed in delight, and Sadie leaned forward to kiss it gently.

"I love it when your cock does that," she said, stroking it gently. She squeezed again, her body tensing, and Jack braced himself for another wave of gas. None came.

He relaxed slightly, hearing it only as he laid back, then feeling the warm, wet splatter of it on his face.

The room went silent, and Sadie froze. As Jack realized in horror exactly what had happened, his cock once again throbbed with pleasure, and Sadie relaxed. He knew it should have made him sick, but it didn't smell any different than the farts he'd been inhaling, and knowing she'd embarrassed herself gave him a little power back. He stared at her sticky, dirtied asshole and wondered if she'd climb off of him, apologize awkwardly and untie him, but she made no move to do any of those things. Instead, still gripping his cock, she spoke.

"I think it's time for you to eat it now."

Jack had given up on fighting his urges now, and his cock wanted more, so when Sadie lowered her ass to his mouth he set about working it with his tongue, cleaning her hole. It tasted sweeter than he'd have expected, which was a welcome surprise after the onslaught of rancid farts, and he gratefully lapped away at the mess around his sister's asshole. She moaned gently, then let out a long, wet fart directly into his mouth. He felt it as it echoed its way into his lungs, and his cock twitched in Sadie's grip. Turned on and enjoying the taste of her dirty ass, Jack tried probing with his tongue, but before he could get it in Sadie began grinding against his face, rubbing herself all over him, the wetness of her pussy leaving its marks on his chin. She let out another fart, and Jack quickly put his mouth over her hole in time for a second, tasting the sour puff of gas against his tongue. He tried to thrust against Sadie's grip on his cock, allowing himself some small relief, and she responded by straining for another fart into Jack's mouth.

Jack felt the rumble move through her stomach on top of him, then the puckering of her ass, and then his mouth was suddenly filled with Sadie's hot waste, warm and soft and tasting every bit as foul as he'd have imagined. He gagged and retched, thrashing against his ties, and Sadie sat back on his face, pinning him down with her weight, trapping him there with a mouthful of her shit.

Out of the corner of his eye, he saw her reaching into her bedside drawer, rummaging for something. He couldn't see what, and all he could think about was the mass of shit in his mouth. His tongue was trying to force it down his throat so that he might stop tasting it, but his throat wouldn't let him swallow. It felt as though his body was desperately trying to work out what to do with his sister's waste, and, to his humiliation, his cock was as hard as ever while his big sister sat there, unfazed, on his face.

Sadie's hand came back into view, holding a small purple dildo.

"I'm going to move now, okay, Jack?" she said softly, grinning slightly. "If you do as I say, I'll make sure you get a reward. How does that sound?"

Jack couldn't speak through his mouthful of shit or the weight of his sister's ass, so he did his best to nod his assent. Sadie quickly climbed off to kneel at the side of the bed, gently inserting the dildo into Jack's mouth. He gagged freely as it pushed a little of Sadie's shit down his throat, but his body allowed him to take it down. "Good boy, Jack. Swallow it all for me, okay?"

She continued gently probing his mouth with the dildo, which was getting increasingly dirty. "You can stop once you've eaten it all, and once you've sucked this clean." Jack knew his quickest way out was to do as he was told, so he desperately fought his body's attempts to reject her waste and swallow it all, bit by bit, just as she told him.

"Open up, show me what's left," Sadie said. Jack did as he was told and she giggled. "That's so gross. You're so nasty, Jack." Before he could respond, she put the dildo back in his mouth, and started working the shit down his throat again.

Jack found that the easiest way to swallow the shit was actually to concentrate on sucking the dildo, so he worked it with his tongue and felt Sadie's mess slide down his throat as he sucked.

"You're really getting into this, aren't you?" Sadie said approvingly, then grabbed Jack's aching balls with her free hand, giving them a squeeze. "Nearly done," she said.

When Jack had swallowed the last of Sadie's shit, he stopped sucking, and Sadie pulled the dildo out. "All done?" she said.

"It's gone," Jack said, shuddering, bile rising in his throat.

Sadie reached up, looking at him with her innocent, hazel eyes, and ran her hand lovingly through his hair. "Time for your reward, then."

Climbing back onto the bed, she positioned herself above his aching, neglected cock. She spread her ass once more for him, showing him her messy, dirty hole. "You want to put your cock up there, don't you?" she said, wiggling her ass back and forth, shaking it for him, teasing him.

"Please..." he said, his cock burning with desperation.

"Okay," Sadie said. "But I want you tell me exactly what you want."

Jack hesitated. "I want... to fuck your ass?" he said, unsure of Sadie's intentions.

"Whose ass, Jack?" She said, grinning wickedly. "Whose ass do you want to fuck?"

"Yours," he said, feeling a little more confident. "I want to fuck your ass, Sadie."

"Tell me that you want to fuck your sister's ass," she said, slowly shaking it from side to side, hovering just above his rock-hard cock.

"I want to fuck my sister's ass," Jack said obediently.

"But it's all dirty," Sadie said, feigning sadness.

"I want it anyway," Jack said, thinking about how much of her shit he'd just swallowed. How much was inside of him right now, filling his stomach. "I want to fuck my sister's shitty ass." She grinned broadly, and gently lowered her ass to touch his cock.

"I'm going to get your dick so dirty," she said, guiding it in.

Sadie's ass was tight, but Jack knew he wasn't the first to have fucked it. She was enjoying it far too much for that. He watched as she worked herself up and down, slowly at first, her dirty hole smearing his dick with more shit with each passing second. The pleasure was immense, and Jack was afraid to let himself relax, all he wanted was to hold on, to keep this filthy, dirty encounter going for as long as possible.

"You going to cum, Jack?" Sadie asked, watching him over her shoulder as she rode his throbbing dick. "You going to cum in your sister's ass?"

Jack nodded, trying desperately to hold it in. The events of the past hour were swirling around his head, although there was no longer any revulsion in it; he had fully embraced his new kink. He told himself he'd have happily swallowed another mouthful of his sister's shit right then, if she'd asked.

"Open your eyes, Jack. Watch me. Watch me take my brother's dick up my shitty asshole." Sadie was going faster now, riding his cock with sheer pleasure, shit smearing itself further across her perfect ass with each thrust.

"I want you to cum, Jack. I want your cum inside my dirty ass," she was saying, riding, thrusting her weight up and down on his aching, throbbing dick.

Suddenly, Jack couldn't hold it any longer, and his pleasure erupted in the biggest orgasm he'd ever experienced. His whole body shook as his cock spurted more and more semen deep into his sister's ass, his head pounded and his vision grayed, and the last thing he saw before he passed out was Sadie sliding his shit-caked dick out of her ass, giggling at the mess she'd made.

Jack was fully unconscious. Sadie was covered in her own mess, with an ass full of her brother's cum, and a quick glance at the clock told her that they only had an hour before their parents were due home. She moved to the head of the bed, where she untied her brother's wrists from the bedposts, then did the same with his ankles. He relaxed, contentedly resting in his sister's filth, and she grinned one more time before turning and crossing the room. She took one last look into the camera she'd set up, and gave it a little wink before ending the recording. She knew that Jack would love watching this back with her next time they were both home from college.~

The following night was family movie night. Their parents took one couch, while Jack and Sadie sat together on another.

Before the movie had even really started, Sadie announced that she was cold, and left the room. She came back minutes later wrapped in a blanket, and sat down beside her brother.

"Are you cold, Jack?" she asked, ignoring the disinterested glance from their parents as she talked over the movie.

"A little," he said. She lifted the blanket enough for him to slide in beside her, revealing her almost-naked body underneath. She was wearing was Jack's favorite shirt, and a quick hike of her leg revealed that she wasn't wearing underwear.

Jack felt his dick spring to life, and grabbed a cushion for his lap. Risking an uneasy glance in his parents direction, he was satisfied that they were unaware of the situation. He reached across, feeling Sadie's welcomingly wet pussy, sliding his hand lower to slip a finger into her waiting asshole. She shifted her hips slightly to let him inside, never taking her eyes from the movie. He probed as deep as he could, just as she'd told him to earlier that day. She turned to look him in the eye, and raised her eyebrows playfully. He knew that was the signal to stop, and he did as he was told.

"Are you hungry, Jack?" she asked.

"Not really," he said. She narrowed her eyes at him in response, and gestured with her eyes to his finger.

He looked down, and it dawned on him what she was telling him to do. He raised the finger to his mouth, and sucked it clean, relishing the taste of his sister's shit once more. He stole one last guilty look over at their parents before reaching under the blanket for more.

Sadie's Sequel

After any other flight, Jack would have been tucked into the thick, soft blankets of his hotel bed with a box of takeout on his lap and some cheesy, no-budget show on low volume. But this time it was different - he had some important business to attend to. Mainly, the business of reuniting with his sister for a night of sordid and unexpected pleasure.

The club was stuffed full of bodies, a wall-to-wall sea of dancing, drinking, flirting, teasing, and everything in-between. With every beat of the music Jack felt as if his chest was close to exploding, a stew of nerves and excitement churning in his stomach.

It was important it was him seeking out Sadie instead of the other way round; he wasn’t even sure she would recognize him. His new hair style and the darker color had completely transformed his face and he looked older, the smattering of stylish stubble adding to this upgraded, distinguished look. All in the name of passing for someone, anyone, other than her own brother.

As Jack continued to wade through the crowd, a familiar figure could be seen swaying and dancing to the music in the very middle of the dance floor.

Sadie looked utterly gorgeous, somehow even more so than Jack remembered. She had lightened her dark brown hair, giving the now-sunkissed locks a delicate, beachy wave. Her breasts were dangerously close to spilling from the sequined crop top she wore, and beneath a playful black skirt flared away from her body, pulling in her already narrow waist and exaggerating her round, thick ass. Surrounding Sadie on all sides were girls her age, each one preened to perfection and showing equal amounts of skin.

As if sensing his presence, Sadie swiveled around, catching Jack’s eye from across the room. Her eyes immediately lit up in recognition and joy. Jack couldn’t help but smile; seeing his sister always set his nerves at ease.

Keeping Sadie in his peripheral, Jack integrated himself back into the crowd as just another dancing body growing hot from the press of skin and movement around him, lost among the music and alcohol.

“Girls - I’ve found one,” Sadie giggled, biting her lip, leaning in so as to be heard over the thrum of music.

“Who?” The girl to Sadie’s left, Rachel, replied as she scanned the crowd intently.

“Tall, dark hair, white t-shirt,” Sadie revealed, “like, three people behind Lola.”

Lola renounced any attempt at subtlety and turned on her heel, immediately latching onto the cute boy Sadie had her eye on. “Ooh, yeah, go for it, babe,” she urged.

Relief flooded through Sadie’s body: none of her friends had recognized Jack as her brother, seeing him as just another random stranger. Now there was nothing stopping her from carrying out every dirty thing she had planned to do to that unsuspecting boy.

Parting from her friends who filled her with words of encouragement, Sadie squeezed between a group of guys, making a bee-line for her brother. When she reached him they shared a joint, coy smile and she lifted herself onto her tippy-toes to whisper into Jack’s ear.

“Fancy seeing you here,” she purred, having to resist pulling him in for an overly-familiar hug, aware of her girlfriends' prying eyes burning into her back.

Jack grinned, bending to bring him mouth to Sadie’s ear in return, “I don’t know what you’re talking about; I have no idea who you are.”

A loud snort let Jack know what Sadie thought of his joke, but she bantered back nonetheless. “What’s your name then, stranger?”

“You can call me… Jason.”

The frown sounded in Sadie’s voice. “Wow, inventive.”

“I was thinking of Jason and the Argonauts,” Jack replied dejectedly.

“More like Friday the 13th Jason. But, whatever. Let’s introduce Jason to my friends,” Sadie gave Jack’s arm a warm squeeze, trailing down to grip his hand tight and led him back through the crowd.

Sadie’s friends continued to dance, obscured by the dark and the flashing lights, seeking out warm, male bodies of their own to flirt with. Sadie placed herself in front of Jack, reaching back to guide his hands onto her ass. Eagerly, Jack squeezed at her firm asscheeks, resisting the urge to slide his hands up under her skirt to feel her skin against his.

As their bodies swayed in tandem, Sadie’s head fell back onto Jack’s chest and her ass pressed firmly into his crotch. The temperature of the club rose dramatically, heat radiating off of Sadie’s gyrating, writhing body.

“It’s so hard to hold it in,” she breathed, barely audible over the thumping music, “every time I press back against you… if you could hear my stomach, you’d know what I meant…”

“D-do you wanna…?” Jack could barely bring himself to say it, his heart beating hard and fast, perfectly trapped against Sadie’s ass, the tension beginning to build between them.

“Feeling your dick between my asscheeks is making me horny… maybe I should treat you… it’s been so long, hasn’t it?”

“Too long,” Jack agreed, memories of their previous encounters flooding back and Jack’s cock began to twitch in interest from within his jeans.

At that moment the song changed and the room-shaking bass kicked in, hitting Jack right in the chest with each measured beat. There, Sadie pushed back firmly into Jack’s crotch and let out the first of several long, rumbling farts, able to match the beat of the music perfectly. They were strong enough to vibrate through her skirt and into Jack who gasped at the sensation, feeling concentrated warmth spread between them.

Too perfect was her timing that no one around them was aware of what was happening between them; Sadie let another fart loose, large enough to cause her body to shudder against him. Now, in a creeping wave the smell of Sadie’s farts began to seep upwards into Jack’s nose, a thick, eggy scent that coated the inside of his mouth as he breathed it in, his body reacting against it and causing his nose to wrinkle.

Around them, the others picked up on the smell, as pervasive as it was. The tight press of bodies shifted uncomfortably, trying to locate the source but as quickly as it arrived it was soon gone, lingering only on Jack’s tongue.

A final, smaller squeak caught against Jack’s body and with that Sadie turned and pulled Jack in for a kiss, hungry, both her hands pulling his head to her mouth and allowing her to slip her tongue in. The two kissed passionately, lips wet and ready, and the music changed. A popular song caused a surge to roar through the crowd, everyone pressing to get onto the dance floor, and Sadie saw her chance. Blindly, she grabbed at Jack’s hand and dragged him away from the crowd, fighting the tide of people trying to get on.

“Lucky bitch,” Rachel snickered, raising an eyebrow at Lola as Sadie and Jack disappeared from the group, “I wish I was getting some tonight.”

Bursting into a one-person restroom, Sadie had timed their escape perfectly - there was not a single other person in sight. The two crowded into a single cubicle and Sadie locked the door; the music was muffled and hollow-sounding, it was as if they had been transported into a completely different world.

“Sit on the floor in front of the toilet and lean your head back,” Sadie instructed him. There was an urgency in her voice, a spark of electricity that Jack couldn’t ignore; he hurried to the floor only half-aware of how sticky and moist it was, his attention taken up by the beautiful body in front of him.

As Jack let his head fall back he watched Sadie’s hands sneak up under her skirt and pull down a tiny black thong, bringing it down her thighs and to her feet.

“What happened back there was just a taster,” she teased him excitedly, “nothing compared to what’s about to happen - believe me.”

Inadvertently, a shudder ran through Jack’s body. Sadie lifted her skirt and there was her perfect, round ass, her skin looked so smooth, Jack wanted to bend in and worship her, wriggling deep in-between her cheeks. To tease him further, she shook her ass back and forth, transfixing Jack, as with each movement the little pink bud of her asshole revealed itself, a hidden treasure.

“I can’t believe how gassy I feel,” she told him.

“Y-yeah?”

“Oh, yeah. It’s been so long since I’ve felt this full, my tummy is almost rock solid. And now it’s all going to be used on you.”

Sadie unzipped her skirt a little, allowing it to rise up her body and putting her ass on full display. The sight was enough to make Jack’s mouth water, now his heart beating faster than a hummingbird’s wings.

“I can feel another fart coming,” Sadie’s voice wavered and Jack knew she was desperate, “it’s making my stomach hurt. This one is going to really, really stink. My asshole is already so sticky from those last ones.”

Hearing her say those words, Jack whimpered a little. It was so, so wrong. Here he was sitting on the floor of a club toilet with his head resting on a toilet seat eager for his sister to bring her asshole closer.

“I wonder what my friends would think, knowing that there’s a perfectly good toilet inches away from me but I’m going to use my brother’s mouth instead.”

“My mouth?” Jack echoed.

“Well, of course, Jack,” Sadie’s tone was playful and light, “you’re going to be my human toilet for the night. That’s why I invited you here, after all. Now, you be a good toilet and stop talking - it’s time to put you to work.”

Before Jack could voice any protests, or even get his head around what was about to happen, Sadie was squatting backwards.

“Open your mouth and keep it open. This is going to be so fucking hot…”

Sadie was grabbing an asscheek in each of her hands, offering Jack an unobscured view of her tight little asshole. She had been right before - it did look a little wet, with a tiny speck of brown on the rim.

And then she was on him, her asshole accurately placed right between Jack’s open lips. The weight of her asscheeks kept Jack from being able to move his head even a little, his nose clamped firmly between them, truly trapped. Instinctively, Jack’s hands rose to grip at Sadie’s thighs, hoping to take a bit of her weight, and happily took a handful of her in each hand.

Readjusting herself just a little, getting comfortable in her own time, Sadie was able to form an air-tight seal around Jack’s lips with her ass, confirming to herself that there would be no escape - for him, and for what she was about to reward him with.

Now, much closer, Jack could hear the angry gurgle in Sadie’s stomach. Long and rolling, the sounds were almost painful to hear - the sound of an unquantifiable amount of gas stored inside her tiny body.

Sadie must’ve known he heard it too because she said to Jack: “I’m not even going to apologize for how loud that was. This is going to be bad. You’re going to have to be on your best behavior, okay? It’s your job to make sure we don’t make too much noise and get caught, because if we do then we won’t get another chance at this. Understand?”

An attempt at a nod was made but Jack couldn’t seem to move his head in any direction, pinned as he was to the seat. He moaned, signaling his acknowledgement, and shuddered as he felt his lips vibrate against Sadie’s asshole.

“Good boy. Get your cock out, too, I want to see how much you’re enjoying being my little toilet slave.”

Embarrassed but willing, Jack released his grip on Sadie’s thighs to unzip his jeans and slip his cock out of the opening. He was still half-erect from her grinding and farting on him earlier, taking some maneuvering to free himself. He wished he could see Sadie’s reaction, but he could see nothing but her asscheeks above him.

“You’re doing so well, your face fits my ass perfectly,” Sadie wiggled her ass, somehow slipped slightly lower and for a moment Jack could no longer breathe through his nose.

His body seized, hands flying up to Sadie’s thighs once more, muffled howls breathing out onto Sadie’s asshole as he did so.

“Something wrong?” Sadie teased. Jack felt another shift in her weight and now stars were beginning to form in front of his eyes. The light caress of something along his cock caused him to start, bending his legs to plant his feet, needing now to struggle out from underneath his sister; it was too much, his chest was burning, all he needed was to-

And then he could breathe, Sadie had risen just a little in her intent to stroke his cock with her foot, freeing his nose. Jack gasped, adrenaline rushing through his body and causing his head to spin, and as he took in that first, life-giving breath, Sadie released a spluttery, explosive fart directly into Jack’s mouth. The smell of her asshole sucked directly into his body, meaty and warm and smelling of something unique to Sadie. It was all he could smell now, but he gulped it down nonetheless, scenting the element of sweetness in her, and the air was hot. It repulsed him, the wetness of the fart evident in the noise it made, but that didn’t stop him from trying to catch his breath, forced to take Sadie’s fart in the process.

“That was a big one, huh?” Sadie taunted Jack by dipping a little lower, cutting off his air again briefly, then leaning forward to free him. A small brief fart fell from her asshole as if by accident and this time it was accompanied by a small squirt of warm liquid shit that dripped directly into the back of Jack’s throat. He retched, and Sadie leaned back to force Jack’s head backwards into the seat. There was no option but for him to swallow it.

“Don’t disappoint me now,” Sadie murmured; she could feel a tremor in Jack’s hands as he fought the wave of nausea flooding his body, “this is what you’re here for, after all.”

Jack swallowed, finally, but the taste remained. It was similar to how her farts had tasted but somehow earthier and sour. Realizing he had eaten his sister’s shit only intensified the shake in his hands as he clutched at Sadie’s thighs in a helpless attempt to ground himself on something, anything.

As Jack struggled beneath her, Sadie’s eyes were latched onto her brother’s growing, twitching cock. As much as his mind fought to process what was happening, his body was responding keenly, almost seeking out the gentle grazing touch of Sadie’s foot once more. If Jack had thought to bring his hand between Sadie’s legs he would have found her soaking wet, utterly in bliss at having reduced her brother to her dirty toilet slave.

Eyes flickering shut in pleasure, Sadie moved Jack’s hand onto her stomach, pressing it lightly.

“Feel how bloated I am?”

Jack rubbed Sadie’s cute belly, feeling how distended it was, careful to keep his touch light. His wary touch caused Sadie to giggle.

“I haven’t used the bathroom in three days, all of that is stored up inside me; I’ve been saving it for your visit. I know my tummy feels big now, but trust me - by the end of the night it’s going to be nice and flat… so, where do you think all of this is going to go?”

If Jack had felt lightheaded before, what he felt now was double, triple the intensity. A series of quick, raunchy farts fell into Jack’s mouth and there was no time to process what was happening as now there was something solid touching his tongue, snaking into his throat. It was a long, moist shit, dropping - impossibly big - from Sadie’s tiny asshole. If he had been able to see it, there was no way Jack would have been able to comprehend how wide Sadie’s asshole was currently stretched, all of that slimy shit traveling directly into his gaping mouth.

“Don’t chew it, just take it,” Sadie commanded, her voice fluttery and light with the relief of finally expelling, “let it slide all the way down, whole. Your throat is my personal human sewage pipe and your face is the toilet seat.”

As more and more shit left Sadie and crushed itself into her brother, Jack couldn’t help but resume his squirming. It was too much, an unrelenting release, clogging his throat and even coating his teeth. His throat worked to keep from rejecting it, wanting to please her, wanting to do well. Her little sighs caused his cock to perk up in interest.

Remembering how hard he was, how aroused he felt, caused shame to prickle at Jack’s skin; the ache in his balls a constant reminder of how much control Sadie had over him.

“Come now, don’t choke.” Sadie couldn’t resist another giggle, spreading her legs a little wider to stop herself from being bucked off. “Did all of my shit clog my personal toilet?

I’d have thought you would do better than that, after all, there’s a reason why you’re beneath me. But, I guess you just need to be taught. I’m not getting up until you’ve swallowed all of my shit. We’re not even close to the end.”

Frustration with his own body was beginning to build and Sadie’s full weight was back on him, cutting off the air supply. Now it was a race against time. Jack’s throat worked furiously, his eyes watering, the shit in his mouth mixing with his saliva and becoming watery, mercifully easier to take, but somehow more pungent in the process. A small coil of fear that he would vomit started to tighten in his gut, only the thought of how disappointed his sister would be in him kept Jack moving, gagging the clumpy shit down in dejected, labored swallows. His vision was swimming in front of him, everything was Sadie’s ass, everything he could feel, taste, smell, see was his sister and the content of her bowels. One final gulp and his mouth was empty, somehow, finally, and in a desperate attempt to signal his success to Sadie he reached out his tongue, circling her asshole and scooping up the remnants of shit he found there.

Vision darkening, Jack’s rock hard cock strained away from his body, yearning to replace his tongue, wishing he could sink it into Sadie’s asshole lubricated with her own shit.

Finally, thankfully, Sadie rose and Jack was able to suck in a life-giving breath before she settled back down, lighter this time, but still keeping him in place. Head swimming, Sadie’s voice seemed distant, ethereal.

“Let’s finish up. This time, I don’t want you swallowing, okay? Keep it all in. You’ve done so well, don’t fuck it up now. I’ll tell you when you can swallow.”

With that, she relaxed her bowels once more, a fervent gurgle sounding from her stomach in happiness as the last of her shit slopped out of her asshole and into Jack’s awaiting mouth. It spread and puffed out his cheeks, filling them and stretching them outwards, more and more until Jack started to panic; surely it wouldn’t all fit?

And then she was done, standing in front of him, and for the first time Jack noticed the terrible strain on his neck from having been bent back for so long - it seared and ached in every attempt to straighten it.

“Keep your mouth closed, no swallowing.” Sadie reiterated. Reaching for some toilet paper, Sadie wiped Jack’s mouth tenderly, catching any errant stains, before turning her attention to herself, cleaning up and stepping back into her thong. “I know it seems like a waste,” Sadie sighed, throwing the used tissue into the toilet behind him, “but there’ll be plenty of time for you to lick me clean, don’t you worry.”

Now it was Jack’s stomach’s turn to roll and gurgle and splutter. What he had swallowed previously had finally hit his stomach and it wasn’t happy, wanting to reject it. With his mouth full, Jack had no choice but to force down the retches that rose and fight the nausea; he didn’t want to think about the consequences otherwise.

Wobbling, Jack made it to his feet, his mouth stuffed like an animal storing nuts for the winter. Sadie, her hands tantalizingly soft and warm, tucked Jack’s throbbing cock back into his pants and re-zipped his jeans, giving him a little tap for prosperity. Then, wordlessly, she led him back out into the club.

The crowd was beginning to thin, enough time had passed that the best tunes had been and gone, and now half the dance floor was empty. Sadie’s friends were where they had left them, now joined by a few boys who lingered around them expectantly.

Sadie caught Rachel’s eye. Her friend waved at her in excitement, knowing she was going to hear all about it in the morning. Sadie mouthed something about leaving and Rachel pulled an exaggerated sad face, before leaning over to Lola to communicate the message. The two of them waved goodbye to the pair from across the dance floor.

Once Sadie and Jack waved back Sadie whispered out of the corner of her mouth, “You had better not get any shit on me,” before kissing him briskly over his clamped lips, putting on a little show for her friends. Jack had to clamp his teeth shut to keep from anything spilling out, the acidity now burning the back of his throat and nose.

Finally, it was time to leave, and Sadie slipped her arm through Jack’s, savoring his touch. As soon as they were out of sight, Sadie gave Jack a little nudge and a squeeze, and he knew it was time to swallow. As he did, his whole body convulsed violently, as unnatural as it felt to swallow such a substance down.

“Go on, you can do it,” Sadie urged, her tone soothing. His eyes watering, Jack managed to cough down the last of it, not losing any of the taste in his mouth, and Sadie rewarded him with a hug.

But, even the hug was a ploy. Her arms around his waist squeezed just enough to cause his stomachache to intensify, a splutter rising in his mouth.

“That’s not fair,” he muttered, feeling the ache in his jaw from Sadie’s weight previously.

“Let a girl have her fun, eh?” Sadie chided him jokily. Her hand shot out for a taxi, and Jack realized that the night had only just begun.

~

“Wait here, I’ve got a surprise for you!”

Lying on his back on Sadie’s soft, plush bed with his legs hanging off the end, Jack allowed himself to relax momentarily. The whole taxi ride back, Sadie had her thigh on his lap, shifting it into his stomach with every bump and turn in the road. Torturous.

Sadie’s room wasn’t how he had expected it. Growing up she never tidied, often getting into trouble with their mom for having one too many clothes thrown all over the floor.

Here, Sadie had taken a little pride in her surroundings. Art and plants hung from the walls, scented candles danced lit in each corner, and fairy lights circled the room creating an intimate vibe. Jack could’ve happily spent the night soaking in Sadie’s presence in this room, but he knew she wasn’t done with him just yet.

Outside the door Jack could hear the tinkling sound of Sadie’s adorable giggle mixed in with another sound, a different giggle from someone he didn’t recognize. It was getting closer and Jack peered up just in time to see Sadie return, followed immediately after by a gorgeous, young Latina.

“Jason, this is Camila. Camila, meet Jason.”

A pink flush rose on Camila’s cheeks, “So lovely to meet you, Jason.” Her voice was laced with sex, breathy and well-spoken. Her dark eyes glistened in the light of the candles, and Jack couldn’t help but feel as if she was undressing him with her eyes as he lay in front of her.

“Camila’s my roommate. She’s the one who got me started filming those fetish videos for money. I would never have known it was a thing before she mentioned it.”

“You don’t have to thank me,” Camila shrugged casually, “although 20% of your paycheck wouldn’t hurt.”

Sadie giggled and nudged Camila playfully with her shoulder. “I’ve got you something better than that. I know you’ve always wanted to fuck a guy while he was being used as a toilet…”

With a tilt of her head Sadie made her intent clear and Camila didn’t need any further prompting. Suddenly, they were on him. Camila scrambled at Jack’s pants to fish out his cock, her little pink tongue darting out to wet her lips, excitement igniting in her eyes.

Meanwhile, Sadie was undressing behind him, losing her skirt and thong completely this time. Jack didn’t know where to look, everything was happening so quickly.

Camila had freed his cock from his boxers which now started to swell, his pent-up frustration from earlier surging back with full force. With Jack’s legs hanging off the end of the bed it made her easy to stand and squat, grinding her ass back and over Jack’s growing erection. Her ass was so full and smooth, her beautiful skin almost shining in the light. The sensation of her rocking back and forth, of her asshole puckering and fluttering along his shaft, was unbelievable.

Now completely naked, Sadie lifted her thigh over Jack’s face so she could straddle it once more, sitting on her knees with Jack directly between her cheeks. Peering over her shoulder, Camila giggled at the sight, obviously impatient for what was to come, savoring the sensation of Jack’s hardening cock along her asshole.

“Are you ready for Round Two?” Sadie asked, but it was a rhetorical question with Jack rendered unable to reply, her ass squishing his mouth. “I’ve still got a lot left to give you, so get ready. You better start sucking.”

Above his lips, Jack felt his sister’s asshole pucker and stretch. A few silent farts were released, they ghosted over Jack’s lips gently in little short spurts, the smell reminiscent of the taste he had in his mouth. Then, she was shitting, dropping the long length straight down into his throat, a gasp escaping her at the pleasure of the release.

Camila took this as a sign and reached around herself to take Jack’s now fully-erect cock and sink down onto it, taking his entire length into her awaiting pussy. Jack couldn’t help but moan, causing him to gurgle on the shit in his mouth, as he felt Camila’s soaking wet pussy take him in, inch by inch, indulging herself on his length.

Distracted momentarily by Camila, Jack suddenly realized that Sadie was still filling him with her shit, refusing to lift off of his face. It was more shit than Jack could have ever thought possible. His already aching stomach protested with agonizing cramps - the feeling of being impossibly full - and yet there seemed to be no end. Even though he was doing his best to swallow, his body was starting to betray him, his lips cramping and his throat burning and his attention was being snatched back by Camila every time she sunk down onto him.

It was impossible, Jack started to writhe and wriggle, but the weight of the two girls on top of him held him in place, a toy in their game. A burning sensation shot through his face and Jack realized with a start that a sliver of shit was beginning to leak out of his nose, so packed was his mouth that there was nowhere else for it to go. Camila was picking up speed, the smell of Sadie’s shit thick in the air, her hips rolling, gasping in pleasure, each movement inadvertently shaking Jack and causing his already abused stomach to tighten and seize.

Sadie shifted slightly and Jack managed a quick breath just as Camila slammed back into him and his toes curled and it was all too much, Camila’s pussy was flexing and twitching around him while Sadie’s shit inundated his mouth and he was cumming, now, deep inside of Camila, unable to even warn her with his mouth so full.

For a moment, Jack wondered if he had blacked out, as when he was able to process what was happening his mouth was empty and Camila was standing looking down at him with a wide grin on her face revealing a perfect set of teeth. A thick strand of white cum was dripping out of her pussy and her dark eyes were wild with arousal. Sadie was in the process of climbing off the bed, looking extremely pleased with herself.

“Camila,” Sadie said, a twinkle in her eye, “swap places with me.”

Camila glanced back down at Jack’s softening member, an almost imperceivable pout forming on her face. With a certain reluctance to her movements, Camila crawled onto the bed to throw her thigh over Jack’s face while Sadie sank to her knees in front of Jack.

In an absurd moment, Jack was suddenly wracked with nerves; he had only ever been abused by his sister’s asshole before, and now here was a beautiful woman presenting to him her little opening, her strong thighs bracketing either side of his head in a graceful display of dominance.

But there was no time to feel any discomfort. A light touch on his cock caused him to jerk in surprise - there was something hot and wet, the tickle of a breath between his legs, that caused his erection to twitch in interest. Then Sadie’s mouth was there and it was eager, relentless, immediately taking in Jack’s whole length, plunging it deep into her throat with a hungry moan. It felt as if her hands were everywhere; stroking his thighs, cupping and gently tugging his balls, gripping the base of his shaft to steady it as her lips worked up and down. The wet slide of her tongue against the underside of his cock caused his breath to transform into deep gulps for air.

Jack was stunned, happily so, experiencing his sister skillfully work his cock for the first time. He almost wished he could watch, but that would mean missing out the weight of Camila’s ass on his face.

“Are you ready, Camila? Make sure he’s breathing them all in.” Sadie said.

“Oh, I will.” Camila settled in readily. “I’m going to gas this boy’s brains out.”

In quick succession, Camila let out a series of loud, bass farts, her first of the night and ripe in smell. They blasted directly into Jack’s nose, causing him to cough and splutter in surprise. This made the girls burst into a round of giggles - Sadie’s giggle vibrating against his cock.

“Sadie, I think I need to shit, too,” Camila’s voice was full of excitement at the prospect, causing Jack’s cock to surge with blood; unable now to stop his body reacting in such a way. “Do it!” Sadie exclaimed. “Give it to him good.”

Obediently, Jack let his mouth fall open and Camila’s asshole dropped lower until it was sealed over Jack’s lips. Almost instantly her asshole opened and her shit started to make its way into Jack; her load was coarse and thick, enough to make Jack whimper in response, in fear, wanting to change his mind but being unable, still pinned down as he was.

A cold sweat broke out over Jack’s body as the taste of Camila’s shit washed around his mouth, struggling to keep it down, each swallow more difficult than the last. His thighs and hands tensed and released, dry heaves shaking his entire body.

“I have an idea…” something in Sadie’s voice caused panic to skitter across Jack’s skin, “Make sure you’ve got him tight, Camila. I don’t want him going anywhere.”

Sadie’s mouth and hands were gone from Jack’s cock, the cold air sticking to the wetness that pooled around his balls. He was so painfully hard, now, and the loss of contact was teetering on cruelty. Her hands were everywhere and nowhere, until Jack could feel a definite weight sitting on his bloated, rumbling belly.

“Mmmpf!” Jack squealed, unable to help himself, his mouth and teeth saturated in Camila’s shit and he was horrifically close to vomiting. But, there was no stopping his sister. Sadie started to bounce her ass directly onto Jack’s stomach, up and down again and again, crushing it downwards with lethal accuracy.

Jack’s moans only got louder, more panicked, lost in Camila's asshole and muffled by her asscheeks. His stomach was bubbling, seizing, the pressure building to dangerous heights. She had to stop, she needed to stop, or it was going to be too late.

Sadie bounced harder and harder, little giggles exploding from her lips, joyous and evil and playful and cruel all in one. In one final movement, Sadie lifted herself higher than before and let herself come crashing down, ass connecting with Jack's stomach, and there was no stopping it. All of the contents of Jack's stomach came spurting out, a violent stream of shit from throughout the night oozed from his body and coated his face, ran from his nose, dripped down his neck. It covered Camila’s ass. The smell was horrific, mixed with bile it was unbelievably acidic and sour, burning Jack’s nostrils with every raggedy breath he took. Tears wetted his eyes, his stomach churning with the smell and sending out another pump of vomit directly onto the bed.

At the sight, Sadie was enthused. Swiftly, she shifted back down Jack’s body and gripped at his aching cock, guiding it straight into her tight, needy pussy. Her moans were instantaneous; she had been wanting this all night and it showed. The need with which his sister was riding his cock had Jack immediately back on edge.

Not to be outdone, Camila let loose a bubbly, repulsive fart, forcing it through the liquid shit and vomit coating her ass and into Jack’s mouth, the gust spraying little droplets of shit all over the bed, her thighs, Jack’s face.

Jack let out a howl, body tensing, his sister’s pussy unbelievably good as he came once more, and Sadie couldn't take it either. She gripped at Jack's thighs as she shook and shivered, pleasure like she had never felt before shooting heat through her veins. They both gasped for breath, for Jack the room spanned in every direction.

After a moment of recovery, the two girls peeled themselves away from the spent Jack, whose body was plastered on the bed, looking as if he would never leave. Camila was pointing at something and Sadie couldn’t help but smirk with a mixture of surprise and confusion as she followed Camila's finger to see Jack was still hard, so much so that his cock stood straight out from his body.

“That deserves a reward, I think,” Sadie murmured cryptically, turning and spreading her asscheeks one last time. Jack could only watch as a fat, sloppy shit came out of her asshole, curling with startling accuracy around the sides of his erect cock, inching up its sides until his cock had disappeared and only a mound of shit remained. It was so hot, so slick, that cum leaked from the tip of his dick and down the sides of the tower.

“I can’t wait to do this again,” Camila jumped a little from foot to foot in anticipation of what was to come.

“We’ve got all of spring break left together, “ Sadie noted contently, “so it’s a good thing we’ve got our own personal toilet with us.”
