Fartface

PART 1

Asha was going to watch her favorite TV show when she saw Keitaro alone in the living room. It was a rare sight, seeing as he was usually out or in his room at this time of day. He was lazily sitting on the couch watching an anime, which he didn't seem to show much interest in. Asha was a bit irked about this as she knew he wasn't going to graciously let her change the channel. "Oh I know, it's the perfect moment to prod him into revealing the nature of his relationship with Nilüfer. Time for some embarrassing questions," she thought mischievously.

"Hey, little bro! how is that whole training with Nilüfer thing going?" she asked abruptly.

"W-what!? How do you know I train with Nilüfer?" He replied dumbfounded.

"Oh I just ran into her the other day and she mentioned something about training with you. So how is it going ?"
There was no need to ask really, the results were clearly visible. She already noticed he was bulkier and more muscular than before, it was quite a transformation.

"W-well it's going great! I mean she's big and strong and a great teacher, I'm learning a lot!"

"That's cool! Glad to hear it. So... are you two dating or anything ?" she inquired playfully.

"W-what ?! N-no we're not dating! W-why would you ask that ?" Keitaro started to sweat and his face turned red.

"Aww, it would have been so hilarious if you were! From bully to lover! That would have been the best love story ever! Just imagine the look on people's faces! Especially with the height difference between you two" Asha was laughing at the idea.

"What did you exactly talk about with Nilüfer ?" Keitaro asked angrily with a serious look on his face.

He seemed wounded by the height remark, "he looks so cute when he is flustered like that, like a fragile little puppy trying to look intimidating. Let's see how far I can push him !" she thought with a devilish grin.

"Oh, nothing really! We just chit-chatted, you know, girl's stuff. BUTT... she did mention that you guys ASSociated because you ASSpired to become stronger, she also said she was ASStounded by your ASSiduity. I can attest to that, you're starting to look ripped bro" Asha was trying to keep a straight face while making all these puns but she was giggling really hard inside.

Keitaro was furious, "Why you fucking bitch!! How do you know!?" He yelled at the top of his lungs and charged toward her.

Asha easily dodged his attack, "How fucking dare you call your sister a bitch! Mind your mouth, you little brat!" she shouted with a dark look on her face.

Keitaro tried to attack her again but she was much faster, she avoided his sloppy lunge and grabbed his hair with her hand. "Apologize now or else...!" she threatened.

"Screw you, bitch!" he replied defiantly.

Asha sighed loudly and, with uncanny strength, brought him to his knees while turning her back around, his head was now on a collision course with her butt. Keitaro's eyes widened in horror and he tried to pull away but his sister's grip was too strong, his face crashed into her soft, round butt cheeks with a loud smack. Her big ass was now totally engulfing his face and she could feel her tight jeans rub against his nose.

"I feel like you need another lesson in manners" she said mischievously.

"N-nooo! P-pu...lease, not... a-again!!" he mumbled desperately.

Suddenly, she farted loudly right into his face, forcing him to inhale her rancid gas. "You bring this on yourself, Kei. Now breathe in deeply and enjoy!" she said jeeringly. Asha was ruthless and she kept farting on Keitaro's face, her long and bassy farts echoed through the room. Keitaro started to look light-headed from all the methane he was unwillingly sniffing and started to feel nauseated.

Asha breathed a sigh of relief "I've been holding that for a while, it feels so good to finally let it out!" she exclaimed. Keitaro was wailing in misery as he was forced to endure the sickening smell of his sister's flatulent ass. After a few minutes, she finally let him go, and he collapsed to the ground, coughing and gagging.

"It's not over yet" she said threateningly. She had other plans for her little brother that evening, he had been brash, rude, and very disrespectful lately and he clearly needed to be taken down a notch.


PART 2

Keitaro was waiting in ambush for his sister to come into the living room. a moment before, she told him to get ready to watch “Campus Curfew Chaos” with her.
“That dumb fucking sitcom,” he muttered under his breath. He had no intention of watching it and no intention to follow her rules, but he was trapped, she locked him in and told him before leaving that she was going to get more comfortable and get a snack first and then come back. So, he was waiting behind the door, his back pressed against the wall and his eyes glued to the only entrance to the room. He heard a familiar sound in the background, the opening music to “Campus Curfew Chaos”.

“Ugh how can anyone watch this stupid shit?” he thought as he gritted his teeth. Distracted by that loud theme music, he didn't hear the door unlocking. Suddenly, the door opened wide and struck him in the face. His sister walked in at the same time, immediately noticed him and snapped, “What the hell are you doing there?”

He smirked a bit dazed, and pounced on her, "Round 2 Bitch!" he yelled as he grabbed her arm forcefully.

It was over in an instant, she reversed the hold and had him in a tight headlock in the blink of an eye. He went limp, defeated. "Grrr....How is she so quick and strong?" he thought to himself while she was grinding her fist into his scalp.

"You little SHIT! I already told you to NOT call me a bitch! Are you trying to get me MAD on purpose!?" she shouted, furious. "Oh, you're in for it now!" she snarled, "Get down on all fours right there!" she commanded as she let him go, pointing to the floor.

He complied and got in the position she asked for; he could tell she was really angry, it would be stupid to provoke her further.

She stood over him, her face still red with rage, and spoke in a cold and stern voice "Now we're going to watch my show, like we planned, and you're going to serve as my footrest, don't move and shush".

He obeyed, mumbling in agreement and he kept the pose as she sat down on the couch. He soon felt the weight of her feet on his back and his face grew hot with embarrassment. She began to watch her show and ignored him completely except for the occasional kick with the heel of her foot. He could hear her fiddling with her phone and laughing in between scenes. As he heard the phone clicking, he started to feel paranoid, wondering what she was doing, “What if she is taking pictures of me? maybe to blackmail me like Nilüfer... or just to humiliate me even more,” he thought in distress. After about half an hour, the show ended, she got her feet off of him and he let out a sigh of relief.

"Stay still! There's still an episode coming up, I just thought I'd sit on your back for a change... you know, to try you out as my chair," she said with a hearty laugh.

Feeling completely embarrassed and defeated, he stayed still and hoped that she wouldn't notice how red his face was.

She walked over close to him, turned around, and slowly plopped down on his back. He suddenly felt her weight on his back and briefly struggled to keep his posture. She was heavy but the intense training he was going through with Nilüfer was bearing fruits here, he was able to remain stable. She adjusted her position, making sure that her weight was evenly distributed, and then began to sway her hips back and forth. "Gotta say, you're very comfortable Kei," she said casually, and he couldn't help but blush at her words.

All of a sudden, all he could think about was her sister's ass. Visions of it flooded his mind; How big, round, and shapely it was; How it was pressing against his back; How it wiggled, almost massaging him, and he found himself getting aroused. He quickly tried to shake the thoughts from his head, but it was too late, a huge boner had already formed in his pants. "Dammit, it's my sis' butt!" he thought in panic, "What's wrong with me?!"

He was in a trance, he couldn't think straight, a torrent of lewd thoughts and images was running through his mind and he felt like his head was going to explode.

"What's the matter down there? Am I too heavy for you little bro? Awww..." she exclaimed as she patted his head gently with her hand.

"hnggghh..." he let out an involuntary moan as her hand made contact.

"Need a breather?" she asked with a giggle, and before he could say anything she grabbed his head and pulled it backward. At the same time, she leaned on her side so that her ass was pointing directly at his head, and then moaned loudly while releasing a huge fart right into his face. "Breathe THIS fartface! hahaha," she exclaimed, laughing hysterically.

She held his head up there for a few seconds to make sure the smell of her fart filled his nostrils and then she finally let go. "Phew! I feel better, this one has been brewing up all day!" she sighed.

"What the hell have you been eating?" Keitaro asked, still trying to catch his breath.

"Veggie burgers and beans! haha do you like the smell?" Asha replied with a satisfied grin on her face.

"Ugh, I think I'm gonna be sick," he muttered softly.

A few moments later, the second episode of "Campus Curfew Chaos" was over.

"You know what Kei, you're actually pretty strong now, I assumed you'd be too weak to handle my weight for this long but you did it!! You also took my fart like a champ, so that's a plus!" Asha said enthusiastically as she ruffled his hair.

Keitaro was speechless, he was still overpowered by that rotten stench.

She finally got up from his back, still laughing, and as she was going to pull him up into a hug, she noticed the huge bulge on his pants. "Ooh really ?!?" she exclaimed, her eyes widening with surprise. "I guess you weren't exactly hating this predicament then, eh Kei?" she said with a mischievous smirk.

Keitaro was too confused to say anything, his mind was still assailed by lewd thoughts and images and so he just stood there, blushing furiously. Asha looked at him with amusement, clearly enjoying every second of his embarrassment.

"Hmm... maybe you deserve a reward for being such a sturdy and comfortable chair-slash-footrest" she said, her voice suddenly turning sultry.


PART 3

Asha walked slowly around Keitaro and then stopped right before him, her eyes meeting his.

"Say, do you like my big ass, Kei?" she asked bluntly, her smirk widening.

He felt like he was about to faint. "I-I-I uh....," he stammered, he was trying to find the words to answer that but His brain crashed like a computer stuck in an infinite loop; he wanted to say yes because it was true, her ass was indeed very ample and attractive, but also, he felt it was wrong to say that to his sister.

"Would you like to really feel it?" she added, her smirk turning into a playful grin. "How about... I sit on your face? I bet you'd like that, wouldn't you?", she continued, while getting closer to his face, her eyes twinkling.

"A-Ash.... I-I... don't think it's a good idea," he managed to say, but his voice was weak and barely audible.

She backed away slightly and smiled at him. "It's okay, Kei," she said with a mischievous tone. "Nobody will know, this will be our little secret." She backed away further and winked at him. "Come on, I know you want to," she teased.

He stared at her in disbelief and shock, unsure of what to do. He shifted his gaze to the ground and tried to think of what to do, but his mind was still overwhelmed. His train of thought was suddenly derailed by his sister's laugh, as she squeezed his cheeks.

"Hahaha it was a prank, you little shit, lighten up." She exclaimed with a boisterous laugh.

"W-wait, that was a joke?!" He exclaimed, his face turning red.

Asha nodded and said flatly "Yup, I was only kidding. Come on now, let's go grab some snacks and let's watch another movie. Your choice this time". she turned around and started walking towards the kitchen.

At that moment, Keitaro couldn't help but fix his gaze on his sister's thick butt swaying from side to side with her confident strides, and he couldn't resist admiring it. Suddenly, the words just flew out of his mouth "hmm I do like your big ass, sis".

".... Fuck did I just say that out loud?", he thought panicked as his face went even redder than it was already.

Asha stopped walking and slowly turned towards him, her eyes wide. She crossed her arms, grinned, and said softly. "Finally, some honesty... Now say what you really want,".

He gulped, his heart was beating faster. He looked into her eyes, she was smiling from ear to ear, it was clear what she wanted to hear.

"P-Please... sit on my face," he said, his voice barely above a whisper.

"I can't hear you," she said in an irritating singsong voice while making an exaggerated hand gesture in front of her ear.

He felt a sudden rush of courage come over him and he spoke louder "I said, please sit on my face."

Asha's smile never faded, then she said in a seductive voice. "Beg for it".

"Please, sis, please sit on my face, I'm begging you." he said in a pleading voice, his eyes never leaving hers.

She slowly walked towards him with an excessive sway of her hips, and when she was close enough, she whispered "I didn't know you were such a pervert, little bro", her breath tickling his face. "Now put your head right there, my butt needs a good cushion," she said, pointing at the sofa.

He obeyed immediately, sat on the floor, and rested his head on the sofa while his heart was pounding in his chest. She turned around, bend over, and stayed balanced in that pose for a few seconds. He held his breath and waited, his vision was now almost filled with Asha's massive butt covered in tight yoga pants. The anticipation was killing him, he desperately wanted to feel her weight on his face. Everything suddenly seemed to slow down and then she plopped down forcefully on his head, the power of the impact made a satisfying smack sound and her butt cheeks were now covering his entire face like a mask. He gasped, her weight felt calming and exciting at the same time, he felt her tight ass muscles pressing against his face, her scent was overwhelming.

Asha rocked her butt back and forth, rubbing it against his face, and Keitaro felt like he was in another dimension, he felt as if his head was fusing into her derrière. He was trapped in pure bliss, almost unable to think. She let out a satisfied laugh and said "Hahaha, havin' fun down there? I gotta say, it's pretty enjoyable over here". He could barely answer, all he could do was moan in pleasure.

Under her ass, he lost all sense of time, it felt like this lasted for an hour. He was often gasping for air but fortunately, she periodically lifted her butt off just enough to let him breathe.

"You're still due for that reward for being such a good little chair, Kei," she said casually, "It's getting hot in here, I'm going to take my pants off and sit back on your face again". Asha quickly stood up and peeled her tight yoga pants down her body, revealing her intricate sexy white panties. Then she unceremoniously sat down on his face once again.
"Wait... what the fuck are those panties, there's no way she's wearing them for comfort... did she plan this whole thing and wear them for me?", he thought to himself as he inhaled her scent.

But he quickly forgot about it as he felt her warmth engulf his face again. She proceeded to bounce her butt up and down, her panties teasingly rubbing against his nose. "Now, take your little dick out and jerk off while you inhale my butt," she ordered in a commanding voice.
He was too eager to release all that pent-up sexual tension so he quickly complied and started jerking off, feeling immense pleasure as his sister's luscious ass rebounded repeatedly on his face.

"Hmmm... you're bigger down there than I thought, Kei," she exclaimed in a teasing manner. "Ok listen, you have 5 minutes to cum, after that, I'm gonna get off and you better be done or else...".

Keitaro was exhilarated, his sister's butt was so tight, hot, and fragrant, and he felt himself getting closer to orgasm. However, maybe it was stage fright or maybe it was her bouncing up and down on his face that threw him off, but it was hard to let completely go and finish. He tried his best to focus on the pleasure but the time was ticking and he was getting more and more nervous. Finally, after what seemed like an eternity, she stopped bouncing on his face and instead took a different seating position, the pressure increased greatly on his head and the aroma got more intense. This did the trick, he moaned loudly into her butt as he managed to cum. That orgasm was probably the most intense he's ever had and sent him straight to a state of unadulterated bliss.

"You're 3 minutes too late, little bro," Asha declared in a disappointed tone. He felt her butt cheeks tightening around his face and she grunted like she was trying to squeeze his head with her ass; suddenly, he got blasted in the face with a huge fart, the smell quickly filled his nostrils and he almost gagged.

Asha giggled "Hahaha I bet you're starting to enjoy my farts now, aren't ya? That's gotta be like the fourth one you got intimate with today". She finally stood up and let out a satisfied sigh. "Well, that was fun, but now I got things to do, so clean this up and scram." She said casually as she pointed to the cum on the floor. Before she left for the kitchen, she smacked her ass cheek a few times while winking at him and then pulled her pants back on.

Keitaro hadn't moved yet, his head was still resting on the sofa. He felt euphoric, ashamed and utterly bewildered.
