PART 1

It was the beginning of summer break, I finally had 2 months off school where I didn't have to leave my room, or talk to anybody. It should've been the most relaxing part of the year for a NEET like me, but little did I know it was the start of a new, and horrible chapter of my life.

*BRRRRINGG* The bell rang off at 2:50, and that meant that the hottest, longest school day of the year was finally over. I quickly pushed my desk away from me and stood up out of my chair. I gathered my supplies off my desk, and hastily shovelled them into my bag. Before anyone else I was out the door, most normal kids stayed back and chatted with their friends a bit after school, but I didn't really have many friends, so getting out of school was all the better. I marched home in an especially good mood, and after treating myself to a Slurpee at the nearby 7-11, I arrived at home.

"Olly, is that you?" My older sister, Vanessa called out to me, as soon as the front door shut. "Yeah, I'm home... Where are Mom and Dad" Just as I asked I noticed a small note on the hall table, it said:

*"Oliver and Vanessa, Your Father and I are going to B.C. to visit an old friend of mine who is very ill, Because of her condition she could pass at any time, so we are going to stay with her for a full month to make up for lost time. Vanessa, you are old enough to look after yourself, but I worry about your brother, he seems to lack maturity and the ability to properly look after himself, so I ask that you cook for him, and makes sure he stays out of trouble. Have a good time on your own kids - Love, Mom and Dad"*

As I finished looking over the note, I half-listened to my sister repeating everything I had just read. "I can't fucking believe I have to babysit you, and of course, you had to teach Mom how to use facetime, she'll probably check up on us every ten minutes." Vanessa was loudly whining to herself as she often did, however, this time, her anger fizzled out much faster than usual, almost as if she figured out some benefit to watching me over the summer. "You know what, just cause you're here, doesn't mean I can't still have fun, I'm calling Katie over, I guess she'll be staying with us as well." Vanessa said, almost taunting me. It was like she knew I had a massive crush on Katie.

Katie, like my sister, was two years older than me, but she was way hotter than anyone in my grade, so I didn't really care. She had blonde hair, that was long and flowing, and it always looked so soft and clean, effortlessly bouncing off her shoulders as she strutted around. Her face was cute and round, she had bright green eyes, done up with gently coloured makeup to match her gentle face. Her face was cute as hell, but the thing I always noticed about her was her body. She exclusively wore dainty, muted summer dresses, and they really did suit her. As she walked the dresses would always cling to her body tightly, giving a clear outline of what was underneath. Her big, ample tits always looked like they were about to topple out of her dress, and on the other end was her even bigger, plump butt. Her ass was so perfect, I could always clearly see her two, juicy ass cheeks sway from side to side, brushing against the soft fabric of her dress with every step, almost hypnotising as they moved right to left.

My sister Vanessa was a polar opposite to Katie. While Katie was a cute, shy girly-girl, my sister Vanessa was as tomboyish as they get. It was rare to see her wear anything fancier than black leggings and a t-shirt. She had light brown hair kept in a messy ponytail, and her eyes were hazel. Her face was slightly more mature than Katie's, her bone structure was stronger, and along her cheeks were a few barely visible freckles that met at her nose. For quite some time, Vanessa has been quite the health freak, so she was very lean; and even though she is my sister, I have to admit that her boobs were quite small, especially compared to Katie's! Vanessa's ass, however, was, very, very nice. She spent most of her time at the gym, and I'd wager most of that time was spent doing squats. Her butt was similar in size to Katie's but they were quite different. While Katie's butt was very jiggly and soft, Vanessa's seemed to have much more firmness, as if they were almost all muscle. Her butt cheeks would squish against her thighs as she walked, firmly held up by her favorite tight black leggings.

Katie arrived shortly after my sister called her over. They greeted each other happily at the door as if they hadn't seen each other in years, and Vanessa was quick to lament watching me to Katie, embarrassing me in front of my crush. "Ugh, sorry that we probably won't be able to do much, my loser brother is too useless to fend for himself while my parents are gone, so now I have to play house and babysit him. But at least I don't need to be alone with him, now that you're here." Katie giggled and looked over at me sitting on the couch from the hallway, I tried to avoid eye contact, but I could see her grinning in the corner of my eye. She wore a light pink sundress this time, with a tight beige belt at her waist, accentuating her wide hips. Now I had to worry about hiding my boner as well.

"If you seriously think I'm gonna cook for you, then you must be even stupider than you look. Katie, what are you in the mood for?" Vanessa's tone changed immediately as she turned to ask Katie her preference for food. "Hmm, they opened that new Taco Bell up near your place... how bout that?" Vanessa's eyes widened with joy upon hearing Katie's idea. "Yes! You read my mind, I could kill for some Mexican food right now. Hey, loser, what do you want, you better decide fast or you're gonna starve tonight." I hated taco bell, but I didn't want to go without dinner. "Uhhh, Do they have fries?" The two laughed audibly in the hallway. "That's all you want? Cheaper for me. We'll be back in 20 minutes, get off your ass and do something useful, set the table, can you handle that?" I didn't bother replying.

Time flew by as I delicately arranged Katie's place setting to impress her. I haphazardly tossed a fork and paper plate in the general direction of my sister's spot, and I didn't grab myself anything but a plate. Right on time they got back home. "Wow, thanks little bro! I didn't realise you cared for me this much, it's a shame Katie doesn't get this same treatment, what a rude dinner host." Vanessa knew the effort wasn't put in for her, but Katie didn't catch onto her sarcasm, and she seemed legitimately insulted. I stuttered too much to even speak as I tried to defend myself, and Vanessa offered Katie the nice place setting, twisting my kind gesture into her own.

I was silent as I slowly chewed away at my insultingly small order of french fries, which had clearly been picked at already by my sister in the car. The other side of the table was bizarrely silent, but upon closer inspection, the two girls were just distracted by eating; their large orders quickly caught me off guard. Vanessa had a massive burrito, and her own gigantic order of fries, smothered in cheese, Katie had two burritos,and the two shared a huge quesadilla. Once they finished they both laughed at how little I ate. "Jeez, I guess that's why you're so short, maybe if you ate a little more you wouldn't be so pathetic" Katie was steadily giggling to herself the whole time, even when Vanessa let up on the insults. I tried to turn it around and I quickly retorted with my own, lame insult. "Yea.. w-well maybe if you didn't eat so much you wouldn't be such a fatass" they both went silent, I had forgotten how sensitive my sister was about her fitness. The rest of the night Vanessa was in a shitty mood, and the house was silent until night time. I clicked around online for a bit, then got to bed early at 10 o'clock.

"Shhhhh, shut the fuck up Katie." I was woken up by soft whispering and giggling in my room, I was too tired to react so I just turned over onto my back and tried to close my eyes. Suddenly I felt my bed sink to both sides as if two people had just sat on either side of my bed. I opened my eyes and saw Katie lying right next to me in bed, I tried to sit up, but a hand pushed me back down. "Shh, go back to sleep Olly~" It was Vanessa on the other side of me lying down. I tried to figure out what was happening but before I could get my barrings, my thick, heavy blanket was pulled over my face. I quickly struggled, but now both girls were holding me down, and due to their size in comparison to mine, I was hopeless to escape. I looked to the side, and saw Vanessa shifting onto her side, her tight, leggings-clad ass facing me. I looked over to my left and noticed Katie doing the same, her heavenly, thick ass, less than a foot away from my face, protruding against her cute dress. I asked what was happening, and in response, the girls started to count back from five. "five...four......three........two...............one!"

As they both hit one I heard a massive rumble from my right, and felt a thick, nauseating wind wash over my face from both sides. Did they just fart? As soon as I asked myself, the question was answered by the humid eggy fog entering my nostrils. The smell was so thick and disgusting that I began to gag, I tried to claw my way out of the blanket but the girls each grabbed one of my arms and pulled them over their thighs. As I lied on my back, with my arms stretched out to either side, forced to breathe in the toxic farts these two teenage girls had released, I really started to regret my decision to insult Vanessa. "Eww, Vanessa.. that one sounded gross.." Katie giggled to my sister. "Not as gross as yours, Katie. Was that a silent but deadly one?" Vanessa asked, intrigued. "Hee hee, it sure was.. the perfect kind of gas for a dutch oven~" Just as Katie said that, her stomach growled violently. "Ohhh... this one feels wet..." Katie groaned in discomfort. "Here, I have an idea.." Vanessa said.

She pushed me onto my side, holding my arms behind my back with one hand, and the back of my head with the other, beneath the covers. "Katie, stick your butt out, I want him to feel this one." "Mmm, I like the way you think Vanessa~" Katie replied, as she deeply arched her back, pushing her perfect, juicy butt inches from my face, forcing her sundress deep into her ass crack, accentuating her plump butt cheeks even more. "Any last words, little bro?" Vanessa said, giggling. I pleaded desperately, but as I was trying to speak, she rammed my face into Katie's ass. With ease, my nose was swallowed, deep inside Katie's crack. "Hehehe~ Your brother's nose is tickling me~" Katie giggled, as she began to start bouncing her ass up and down, rubbing her cheeks against my face. s my nose sank deeper into her crack, I smelled her cute perfume, mixed with the still lingering scent of eggs from her earlier fart. She perked her butt up, and the fabric of her dress pulled the tip of my nose up as well, lining my wide open nostrils up with her asshole. One last time her stomach gurgled, so violently that the sound alone made me gag. "Urghhh... here it comes. Goodnight Olly~" Katie strained as the loud, bubbly fart exploded out from between her butt cheeks. The massive, wet fart caused her ass cheeks to flutter against my face, as the thick, deadly gas pumped straight into my nose. Each breath I took felt warmer than the last, and more heavily seasoned with Katie's nasty fart. I realised again that I was trapped in a dutch oven, and that I would find no relief from this horrid odour.

"Ahhhh... yummy~" Katie moaned in relief, as she continued to massage her scent into my nose. I struggled as hard as I could, and then, when I thought it couldn't get any worse, I felt a strong, warm push against the back of my head. "My turn!" Vanessa exclaimed as she pushed her ass against the back of my head, absorbing it between her cheeks. Immediately, with no warning, she ripped a thick, beefy fart against my head. In seconds I was completely overwhelmed. The mixture of the gas from both Katie and my sister trapped under this blanket was enough to make me regret ever upsetting Vanessa. The scent was so thick and unrelenting that I stopped struggling completely, all I could do was cry. "Aww, he's given up already? I guess Mexican food does that to me.." Katie said mockingly, as she and Vanessa laughed.

After I had sucked their wet, eggy gas unwillingly into my nostrils for what felt like an eternity, they stood up and pulled the blanket off of me. "Ewwwwww! That smells sooo raunchy. We really gassed your brother good.", Katie teased, "Mhmm, we sure did.", Vanessa agreed, "But this is not the last of it Oliver. Think of this as your initiation. Starting tomorrow, you have a very important job around here. You're going to be our personal fart slave until mom and dad are back. So you should get some rest, it's wakey wakey at 6am for you, little bro... or should I say, slave. And be prepared to sniff some bad gas, Katie and I are gonna eat a big breakfast, just for you~" I didn't know what to say, and I was still in complete disbelief. Just as my room began to air out Vanessa and Katie left my room. On her way out Katie smirked at me, as she traced her finger all the way up her ass crack, before shutting the door. Starting tomorrow, I was all theirs.

PART 2

"Wake up!" I heard in a shrill girly voice. "You have five seconds to wake up Slave, or else...!" I slowly started to wake up, just in time to prevent whatever "or else" meant. "Im up, Im up.. what do you want Vanessa?" I rubbed my eyes and sat up slowly, as they adjusted to the light I noticed Vanessa and Katie standing above me. "Oh, Katie! You're here too!? Why are you guys in my bedroom?!" Vanessa and Katie turned to each other and smiled. Vanessa said, "Gee, that's a pretty rude way to greet your Mistresses... did you already forget what happened last night?" The awful memories of the night before began to flood back in quickly. "So that wasn't a bad dream then..." I nervously laugh to myself, attempting to cut the tension in the room. "If you think playing dumb will coax any mercy out of us, then you're dead wrong, right Katie?" Katie nodded sweetly to my sister then shot me a troubling, sinister grin. I was really starting to see through her cute, kind facade.

Vanessa and Katie dragged me out of bed and to the Kitchen. I knew they were much stronger than me due to the height and weight difference, so I didn't bother struggling. Unfortunately, the dead weight strategy didn't do me very well either, and with ease, they pulled me by the arms down the hall. "Well, what the hell are you waiting for?" Vanessa asked rudely after dropping me in front of the stove. "What do you mean?" Vanessa grunted loudly in irritation. "Make us breakfast, dumbass!" I had never so much as microwaved myself leftover food, let alone cooked anything. "Do you need me to spell it out for you? Stand up, and start cooking. Katie, what are you in the mood for, eggs?" Katie's face lit up. "Mhmm! And don't forget the bacon, Oliver- I mean slave!" Katie giggled to herself over her mistake, it was actually really adorable, ignoring what she had done to me the night before. Vanessa slammed the carton of eggs, and the pack of bacon on the counter in front of me. "I don't even care, just make all 12. Use most of the bacon too, I'm fucking starving." I was flustered, not wanting to screw this up, because screwing this up would mean more punishment from them. I quickly remembered seeing my mom boil some eggs once, it seemed easy enough. I put a full pot of water on the stove top and tossed the bacon on the griddle while it boiled.

I brought the food to the kitchen table and set it down. "Vanessa! Katie! The foods ready!" I called into the next room, Vanessa practically sprinted into the kitchen. "Fuck I'm hungry. And you refer to us as Mistress Vanessa, and Mistress Katie, but I'm sure you'll get the hang of it." My sister seemed in a much better mood with breakfast in front of her. As the two began eating, my stomach growled loudly. "Uhh, could I have some too, Mistress Vanessa?" "Pfft, at least you asked politely, but no, you can't. Just make yourself something else." Mom and Dad hadn't gone grocery shopping before they left. There wasn't much other than bread left to eat. As I brought my single piece of toasted bread back to the table, I noticed that Vanessa and Katie had already finished eating. "Boy, i was hungry. Look Katie, we finished everything." Vanessa said, surprised. "Mhmm, we sure did," Katie replied in her soft, bubbly voice. Vanessa turned, and quickly noticed my meager breakfast. "Hmph, is that all your having? At least season it a bit." Vanessa said grabbing my plate. She stood up and placed the plate down in front of her on the table, patting her slightly bloated, but still toned stomach. I was baffled at what she could've been doing, but I soon realised what was about to happen.

To my dismay, Vanessa turned and pointed her big, round butt towards my plate. She slowly wiggled her ass out of her pajamas to reveal a tiny black thong, completely consumed by her huge ass cheeks. She clutched her stomach as she took a seat on top of my toast. "Mmmm, this one's gonna be good" She let out a sigh of relief as she ripped a wet, bubbly fart onto my breakfast. After the nauseating fart ended, she massaged her ass into the piece of toast, stood up, and patted the crumbs off of her sizeable, firm butt cheeks. She pulled up her pants and sat back down like nothing happened. "Bon Appetit, slave!" She said proudly, pushing the plate towards me. I looked down in horror at my defiled breakfast, as I looked back up I met eyes with Katie and Vanessa smiling at me, expectantly. They were waiting for me to eat it. Out of fear for what would happen if I disobeyed them, I reluctantly brought the hot piece of bread to my mouth. I couldn't tell if the warmth was still from the toaster, or if it was from my sister's big ass, I prayed it was the former. As the bread crunched into my mouth, I immediately gagged. I didn't think it would be, but Vanessa's fart was still very potent as if the bread was saturated with her gas. I closed my eyes, and tried my best to finish the piece of toast quickly, every bite tasting more like my sister's nasty fart than the last.

After I finished my horrible "breakfast" Vanessa and Katie surprisingly didn't bother me too much, in fact, they left the house altogether to go on a jog. I was happy to finally be alone, and safe from their torture. I went up to my room and browsed 4chan for a while, but even though they were gone for a few hours, time seemed to fly by. "Weeeeeeereee Hooooooome!" Vanessa called out, teasingly. I heard them kick off their shoes, and quickly run to my room. My door flung open, and there stood My sister and Katie. Katie was wearing a pale pink tank top that exposed her soft, flat stomach, and a pair of sporty-looking short shorts. From the angle she was standing at, it was clear that the shorts were too small for her, as they rode up, and wedgied deep in her ass crack. Vanessa, as usual, was wearing what seemed to be her only pair of pants, black leggings, with a baggy t-shirt, tied up to the side with an elastic. "Sorry we kept you waiting, but now we can give you our full attention.." Vanessa slowly walked up to me and grabbed me by my hair. In one swift motion, she turned her ass to face me and dug my nose deep between her ass cheeks. "Mmm, smells good in there huh? It's still all sweaty from jogging, but I'm sure you don't mind one bit." As my face slid deeper into her crack, it felt increasingly damp against my cheeks, and the sour smell of ass crack sweat reached my nose.

"Mmmph! Mmpmmph!!" I tried to scream, but the sound was quickly muffled between my sister's firm ass cheeks. "Huh? What's that? Are you saying *please Vanessa, please let me sniff more of your tasty farts*? Because that's what I think I heard." As soon as I heard her stomach gurgle I quickly began to struggle. "Katie, hold him in there, please. I want him to get a good whiff of this one." I felt Katie grab both of my arms and pull them behind my back. With her other hand, she grabbed the base of my head and angled my face upward. She was holding me so tightly that I knew struggling would be pointless. As soon as Katie secured me into position, Vanessa stuck her butt out against my nose, and arched her back in, forcing my nostrils up against her asshole. "There, he's right where I want him to be..." Vanessa said, before grunting and pushing out a searing hot fart, directly into my nose. "Ughh, do you smell that? Must be that yummy breakfast you cooked for us little bro, hee hee" It definitely was. The thick, hot wind smelt so potently of eggs that it almost made me vomit in my mouth. "Ohhh... I feel a hot one brewing in my gut..." As soon as Vanessa said that, she began sliding off her leggings. In the blink of an eye, my nose was pressed firmly against my sisters gooey thong. I felt her massage my face with her clammy, warm ass cheeks, coating my cheeks in her sweat. As suddenly as she took off her pants, another steamy fart was blowing against my face. It seemed as if her thong string was splitting the air flow just perfectly so that each of my nostrils was getting its own thick stream of gas pumped into it.

Even as I tried to free my face, I was almost motionless. Katie had such a strong grip on me that I had no choice other than taking a deep breath of my sister's hot, eggy fart. "Ahhh, finally giving up, slave? That's a good boy... take nice, deep breaths..." even if I didn't want to, all I could do was obey my big sister's command, and surely enough, I sniffed up every last bubble of her thick, warm fart. "Hee hee, good job. I'll let you out for a little while now." Katie let go of me, and I slowly freed my nose from the sweaty prison my sister's ass had become. "Did it smell good in there?" I looked up at Vanessa, almost in tears from how bad it smelt between her butt cheeks. Her tone turned more serious. "Did it smell good in there?" I reluctantly nodded. "Hee hee, thought so. Anyway, it's only fair Katie gets a turn now, right?" I was horrified to hear this, my sisters gas smelt just as awful as Katies, but there was something even more humiliating about being forced to smell the farts of a girl I had such an obvious crush on. "Oh.. um.. I'm actually not feeling too gassy right now.." Vanessa's smile became slightly less exaggerated, she was disappointed. "Aww, it's fine Katie, we've got tons of time for you to gas up our slave, maybe you just need some time to digest" Katie agreed, and gave me a cute smile. Was she being merciful? I was ecstatic, maybe she felt compassion for me, or maybe she had a crush on me too?

"Well come on then, let's go watch tv. You come too, in case Katie starts feeling gassy." The three of us began making our way to the television, but our journey was interrupted by the buzzing of Vanessa's phone. "Shit! It's mom. Keep a close eye on him, Katie. My mom can stay on the phone forever sometimes." Vanessa ran off to her room, likely assuring our parents that everything was ok here, and keeping everything her and Katie had done to me a secret. "Well then, I guess we'll have some time without her now, thank god. Oh, and hey, thanks for earlier by the way." I said, hoping to get a conversation going with Katie, but she didn't reply, she was too busy analysing our hall closet. "Uh, is there something in there, Katie?" Suddenly, Katie grabbed me by the shoulder, and forced me to the back of the closet, shutting the door behind her. "It's Mistress Katie to you, slave. Now get on your knees." I was in shock, I stood there and looked at Katie, extremely confused. "Are you stupid or something...? I said to get. on. your. knees. I won't say it again." She said much more firmly, placing her hand on my shoulder. I obeyed and brought myself to a kneeling position. "Good, I can finally let loose. I've been holding these in all day. Your cooking certainly didn't help.. hee hee." She said, looking down at me over her shoulder, bouncing her soft, jiggly butt up and down in front of my face, forcing her short shorts to ride up even more. "I-i don't understand, why didn't you just do this when Vanessa asked you to earlier...?" she giggled. "Oh, well... I wanted to get a little more... personal with my torture. I wasn't sure your sister would be comfortable with this, but I'm sure she'll come around to it." She quickly dug her wedgie out from her crack, and then slid off her shorts. She spread her cheeks wide apart, exposing her fully bare ass hole to me. "Open wide, slave."

I was absolutely mortified. I just sat there staring at her asshole, as she grew impatient. She let go of her cheeks, and they clapped together, sealing her asshole off between the two massive butt cheeks. Katie turned around and looked down at me, smiling sweetly as she placed her finger gently on my chin, pushing it down, and softly forcing my mouth wide open. Soon her ass was right back in front of me, she grabbed both of my arms and pulled them in front of her around her thighs. "I hope your hungry, slave." She giggled as she slowly began to take a seat on my wide open mouth. She sat proudly on my face, her weight keeping my mouth held open, while her cheeks swallowed up my the rest of my face. I felt her asshole pulsing against my tongue as she bounced playfully up and down. "Mmmm... before the 'main course' how about you give me a little clean up down there, as a little appetiser..." I couldn't close my mouth, I couldn't move my arms, I was nothing but her seat, so I obeyed her. "Ohhhhh...." She began to moan loudly as my tongue poked against her asshole. "Deeperrrr.... stick it in deeper slave..." Once more I did as she commanded and I slid my tongue right into her asshole. The horrid, sweaty taste made me cringe, but I continued licking to appease my torturer. "Ouuuuuuu...that feels good.... You deserve a nice, big treat..." I pulled my tongue back into my mouth, close behind it followed a sickening hot wind. The thick, humid breeze quickly coated my tongue in the gross flavour of Katie's gas. "Wow... It's one thing to have to sniff a silent but deadly one... but having it pumped right into your mouth... It's delicious isn't slave? I bet, I've been cooking it up all day, just for you slave. Now swallow, you have to make room for the rest of my gas... and believe me, I've got more than enough gas to fill your little tummy up with. I really hope you like eggs..." And with that began an unrelenting stream of Katie's deadly gas flowing into my mouth.

At least an hour and a half later Katie stood up off of my mouth. "Ahhhh, it feels soo good to unload, even better when it's into a little losers mouth hee hee." we exited the closet, and a few minutes later Vanessa emerged from her room. She came into the tv room and sat next to me. "Ugh... what the fuck Oliver... your breath smells like eggs or something.. that's fucking nasty." Katie broke into laughter. "Hehe, anyway, I just got some excellent news from mom and dad..." Katie looked excited. "Really, what it is it?" Vanessa stood up and pointed her butt at my face. "Mom and dad won't be coming back until the end of summer!" Katie cheered happily, while Vanessa continued to shake her butt in front of my face teasingly. "You know what that means slave. You're all ours for two whole months.
