A few weeks have passed since my first day at this new school, and my experiences with Shauna have only gotten worse as the days go by. Not only has she continued to bully me with her awful gas, she also introduced me to an equally large friend of hers named Natasha, who enjoys doing the same thing to me.

“We’re gonna be working in exercise groups today! So find a partner to work out with!” the teacher said. This prompted the two girls to look directly at me smugly, as if they had some diabolical plan in mind. Which of course they did.

“Me and Natasha are going to be working together.” Shauna said to me, “But you’ll be working with us too!” I was quite confused by what she meant, but Natasha specified.

“We’re gonna need your “support” while we work out, so you’re coming with us!” she said in the most threatening way possible. I had no choice but to follow the two, as they dragged me to whatever torture device they would use first.

We arrived at a seated leg press machine, and at first I thought I knew what was coming up, but instead of laying my head on the seat as I expected, Shauna placed my head up against the footrest, keeping my head from moving by standing on my hair as she pushed herself back.

At first, I thought I was safe, but as she pulled herself forward, her massive ass creeping towards my face until there was nothing between us aside from a pair of thin sweatpants and dirty panties. She stayed in this position for a while, suffocating me underneath her massive weight, until she finally decided to push away.

RRRRRRRRRRRRRRRRPPPPPPPPPTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT!!!

As she pushed herself away from me, she released a huge fart right in my face, denying me any fresh air for the few seconds that my face was free. Once she reached the furthest end of the machine, she bent her legs, sending her backside hurling towards me until it made yet another impact with my face, once again smothering me with her mass.

BBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAAAAAAAALLLLL
LLLLLLLLLPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPTTTTTTTTTTTTTTTTTT!!

PPPPPPPPPPPPPRRRRRRRRRRRRRRRRRRRRRRRROOOOOOOOOOOOOOOOOOMMMMMMMMMMMMMM

PPPPPPPPPPPPPPPPPPPRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRFFFFFFFFFFFFFFFFLLLLLLLLLLLLLL
LLLLLLLLLLLLLLLBBBBBBBBBBBBBBBBBBBBBBBBBBBBPPPPPPPPPPPPPPPTTTTTTTTTT!

She continued this exercise for what felt like forever, but was probably not even a minute. Every push was accompanied by a fart, and each pull resulted in her massive weight covering my face.

“Switch!” the teacher yelled, which prompted Shauna to get off of the machine, and for Natasha grabbing me by the hair. “You’ve enjoyed your time with Shauna, but now it’s my turn.” My mind was filled with fear as my head was rested on the seat. I knew what was coming, and I felt nothing more than dread. Her massive backside hovered a few centimetres off of my face, and filled my entire view with darkness, and my nose filled with her stench.

BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAPPPPPPPPPPPPPPPPPPPPPPPTTTTTTTTTTTTTTTT!!!!

Before she sat down, she let out one of her massive farts. As I began to cry, I heard Shauna begin to laugh, only being followed by Natasha, who laughed hysterically as she slowly lowered her rear end onto my face. Beginning her workout.

Natasha’s workout was far harsher than Shauna’s. Shauna at the very least gave me some breathing room, whereas Shauna at least gave me some breathing room, Natasha continued to smother me until her workout was finished, meaning the only air I was given in those long minutes were her occasional farts.

BBBBBBBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRRMMMMMMMMMMMMMMMMMMMMMMMMB
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBPPPPPPPPPPPPPPPPPPPPPPPPPPPTTTTTTTTTTT!!

PPPPPPPPPPPPPPPPPPPPPRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAARRRRRRRRRRRRRRRRMMM
MMMMMMMMMMMMMMMMMMPPPPPPPPPPPPPPPPPBBBBBBBBBBBBBBBBBBBBBTTTT!!

FFFFFFFFFFFFFFFFFFRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAAAAAAAAMMMMMMMM
MMMMMMMMMMMMPPPPPPPPPPPPPPPPPTTTTTTTTTTTTTTTTTTTTTTTTTTT!!

I faintly heard the teacher shout “Switch” once again, and the girls carried me over to the next station. The station we arrived at was the barbell area, where the teacher assigned us to do “barbell squats”. Just the sound of such an exercise filled me with dread.

I saw Natasha pull up this padded bench, carefully laying me on it once she placed it under the barbell. Shauna seemed to completely understand Natasha’s plan, as she positioned her massive backside over my head. Before I could even think about running away, Natasha sat down on my chest, knocking the air out of my body.

“Aw, did I knock the air out of you?” Natasha said sarcastically, “Here, let me refill you!” She bent over forward, placing her backside directly below my nose.

PPPPPPPPPPRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAA
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT!!!

As I gagged, the two girls laughed at me as usual, but this time, they were joined by a few other girls who overheard my suffering.

“Hey, can we use that fart cushion sometime?” one of the two girls asked. I immediately began shaking my head in hopes that they would listen to me, but Shauna had another idea.

“Sure! We’ll be happy to share him sometime! But for now he belongs to us.” Shauna said, completely ignoring my struggles.

“Begin!” the teacher shouted, and Shauna began to do her squats. Each time she bent down, her entire backside enveloped by face, and every time she got up, she released her usual farts, again depriving me of any fresh air. This lasted just as long as the previous exercises, and after that time passed, the teacher yelled switch once again, and I feared for the worse, knowing that whatever Natasha had in mind was likely ten times worse than Shauna’s workout.

Natasha began backing up, with her backside slowly approaching my face. And as she slid back, I noticed that her revealed buttcrack was getting more and more uncovered, as she apparently was sliding out of her trousers. By the time she reached my face, her entire butt had become bare, causing my entire head to easily be enveloped by her massive cheeks, with my nose being pressed right into her asshole.

BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
BBBBBBBBBBBRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
AAARRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPP
PPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPPTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTTT!!!!!

She of course took full advantage of this, letting out an impossibly massive fart directly into my nostrils. This stench was by far the worst thing I’ve ever smelt, to the point where I felt like my nose was melting off of my face. Of course, if that happened I would probably be better off than I actually was.

She rubbed herself back and forth on my face, smearing her ass sweat right into my face, even releasing a small silent fart just to mock me.

After a minute of her smearing herself onto me, she pulled her pants up and got off of me as

Shauna took her spot on my chest, beginning her exercise, which was pretty much the same as Shauna’s exercise, since I guess there wasn’t really much variety to squats.

After a few more exercises, each involving my face being pressed up against one of the two girls’ massive farting backside in some way, we headed towards the final exercise, the exercise bike. The seat was barely big enough to fit my head, and I quickly began to doubt that I would live through this exercise.

My head was placed down on the seat of the bike, facing upwards as Shauna lowered herself onto me.

Once she landed, I felt my skull getting crushed by her complete weight, as well as my face being shoved deeper and deeper into her buttcrack.

BBBBBRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRAAAAAAAAAAAAAA
AAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRRRRRRRPPPPP!!!

As she leaned forward to grab the handles, Shauna let out a moderately sized fart right onto my face. On the upside however, I was no longer being crushed by her complete weight, but on the downside, I now had her filthy buttcrack staring me right in the face, with its stench causing my eyes to water.

“Begin!” the teacher shouted once again, and right on cue Shauna began her peddling, grinding her massive globes onto my face, as well as squeezing out small but frequent farts directly into my nose.

PPPPPBBBTT.

PBBPTTTT.

PPPPPBBBFFF.

PPPPRRROOOTT.

PMMMMPPT.

“Switch!” the teacher yelled for the final time of the day, and while I began to dread whatever Natasha had in mind, the fact that this was almost over was the main thing on my mind.

“Man, my pants are all sweaty from all this exercise” Natasha said, stating what I already was well aware of. “I think I’ll be more comfortable with them off.” After hearing that I began to scream, only to be muffled by Shauna who was still sitting on my face.

PPPPPPPPPPPPPPPPPPPPPBBBBBBBBBAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAARPPPTTTTTT!!!

Shauna farted as she lifted herself off of me, and I noticed Natasha was completely bottomless. I wondered why the teacher would allow this, but that was the least of my concerns.

“Here I come!” Natasha said, spreading her cheeks as she descended towards my face, releasing a long silent fart once she was an inch above my nose.

Once she landed on my face, I felt even more pressure than before, only made worse by the fact that my face was now wedged between her completely unfiltered crack. To make matters even worse, her butthole was opened as she reached my face, meaning my nose was now trapped inside of it, forced to smell the toxic air trapped within her. Natasha definitely seemed to notice this, as I felt her shutter with ecstasy once my nose entered her rear.

Pppppppppppppppfffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffssssssssssssssssssssssssssssssssssssssstttt!!!

Natasha released a massive mostly silent fart right into my nose, filling it with even more of her toxic air. At this point I could only be thankful that gym class was almost over.

“Begin!” the teacher shouted, and I prepared myself for the worse, but there was no way I could predict what had in store.

“Hey Shauna, wanna see me use this thing with no hands?” Natasha said smugly.

“Sure!” Shauna replied with laughter knowing that unlike with her Natasha would continue to crush me with her entire weight.

“Begin!” the teacher shouted for the final time, and Natasha instantly began peddling, once again resulting in my face being grinded by two enormous globes, with their gooey flesh rubbing against me. She seemed to be out of gas for the moment, but that hardly made a difference as my face was already engulfed in her stench.

After a minute of my face getting grinded between the two toxic globes, I heard a faint whistle from the outside world. Natasha finally lifted herself off of me, and though her stench continued to fill the air around me, I decided to take a couple of deep breaths anyways, as I was pretty desperate after that traumatic workout.

Unfortunately, before I could get up to leave however, Shauna grabbed me by the arm and dragged me into the girls locker room...
