Be Careful What You Wish For
by ploxiet

To be honest, Mark was a bit of a loner. This is brought upon himself though as he fears that if he gets close to anyone, they might discover his secret fetish. You see, Mark loves female farts. There is just something about it that turns him on. Mark will watch videos, read stories and fantasize daily about girls farting. Mark has always wanted to experience this first hand but he has never had the chance. This all changed though when he moved to his new school and met Jess.

One day after school, Mark was walking through the hallways to leave the building after having stayed back in class to finish work. As he passes the door to the girl's bathroom he hears a grunt and a loud fart. Of course this immediately sparks his interest so he moves further down the hall and around a corner while keeping his eye on the door to see who walks out. After 10 long minutes the door finally opens and out walks one of the most beautiful looking girls he has ever laid eyes on. Jess has her long black hair tied back in a ponytail and is wearing a loose singlet top with yoga pants that comfortably hugs her ass and highlights the muscles in her legs. She walks off in the opposite direction to where Mark is hiding. He is too busy having his mind blown by imagining Jess farting to bother following her.

To Mark's disappointment he realizes that he isn't in any of her classes so the next day at school he makes sure to drop IT and pickup Biology so he could at least be in the same room as her.

The weeks pass by and Jess never once farts in class. Just as Mark is trying to think of how he can witness her in action, the teacher walks around the room and hands out the outlines for an assignment that needs to be done in pairs. The assignment is about the human body. The teacher says to make things more interesting, he is putting pairs of colored tokens into a bag in which the students draw one out each and you get partnered with whoever matches your color. The bag moves around the room and finally gets to Mark, he puts his hand in and shakes it around praying he is the same color as Jess. He takes his hand out and sees he is holding a bright orange token. The last student draws their token and everyone is instructed to find their match. Much to Mark's joy,
he had the same color as Jess.

Jess sits down next to Mark "Hey there, I'm Jess. What's your name?" She asks smiling.

"I'm Mark, nice to meet you." Mark replies while scrunching up his toes as he does when he is nervous.

"Are you new here this year? I don't think I've seen you before the start of term." Jess asks while sizing him up with her eyes.

"Yeah ahh... I am. My dad got a new job at the... umm... law firm so we had to move here with him." Marks awkwardly explains.

"Oh that's cool. So when are you free to do this assignment?" Jess asks while twiddling her thumbs.

"This afternoon!" Mark blurts out a little too quickly. "I mean, I'm free this afternoon. You can come around to my house. The house will be quiet because my parents aren't getting home until late tonight."

"Yeah that works. I will see you on the bus then" As Jess says this the bell for the end of class rings.

The rest of the day goes by as a blur for Mark because all he can think of how he will have Jess alone with him at his house in the afternoon. The final bell for the day rings and Mark quickly makes his way to the school bus. When he gets on, he spots Jess sitting towards the back with a spare seat next to her. He makes his way down and takes the seat. They talk awkwardly on the way home and Mark has to interrupt Jess to tell her they were at his house.

The two students get off the bus together and Mark leads Jess up the path to the house. When they get in, she follows him through to the kitchen.

"Would you like a chocolate milkshake?" Mark asks politely.

"Sure, that would be great thanks!" Jess replies smiling.

Mark swiftly prepares two chocolate milkshakes and gets Jess to follow him up to his room. Jess looks around the room at all the band posters and sketches that Mark has stuck to his walls. Mark pulls over two chairs to his pc and turns it on.

"You can start working if you want, I just need to go to the bathroom quickly." Mark says with a shy smile.

"Okay, that's fine." Jess replies with a little sigh.

As Mark leaves the room, Jess opens up Chrome. Jess is about to start typing in 'the anatomy of the human body' into Google when she has the idea to look at his browsing history. She hits 'Ctrl + H' and all of Mark's visited websites are displayed on the screen. Jess is reading down the list and sees all the normal social media sites, blogs and gaming pages, nothing out of the usual. Suddenly she gets to what Mark was viewing last night. Sites labelled 'Girl pins down guy and farts', 'BBW farts on small man' and 'Smell my farts'. This takes Jess by surprise but she starts laughing as an idea comes to her. Seeing though Brad is away on camp, she hasn't been able to share her gas with anyone. Now she has the perfect recipient.

Jess hears the toilet flush so she quickly closes the history and searches about the human body. Mark comes back in and they get to work.

After 5 minutes of working, Jess raises her leg a little and lets out a small 'BRRPT'. Mark hears it and turns to face Jess trying to appear as though he is disgusted but he sees that she is just typing away as though nothing happened. Mark starts to smell the air and tries to subtly adjust his pants with his hand to make up room for the mild erection he was getting. Unluckily for Mark, he is spotted by Jess.

"Are you trying to smell my fart? Oh my god! Are you hard right now?" Jess shouts at Mark.

"I ahh... err... umm... ahh..." Mark is lost for words.

"Hahaha don't worry, I'm just teasing!" Jess is almost in tears. "I saw your browsing history. Look Mark, I fart a lot and I was wondering if you wanted to smell my gas from the source." Jess says with a sly grin.

"Ahh.... Really? I mean, yeah sure. This is just so unexpected. I thought you would have been grossed out." Mark says blushing.

"Nah this is my little secret. Just lie down on your bed, close your eyes and relax." Jess instructs while pointing to his bed.

Mark doesn't waste any time in lying down on his bed, closing his eyes and getting comfortable. Jess reaches into her school bag and pulls out her handy torture kit for situations just like this. It includes things like handcuffs, duct tape and super effective laxatives. Jess takes out the cuffs and tape. She climbs onto the bed and takes hold of Mark's arms. She moves them above his head and cuffs his wrists together. Mark opens his eyes and sees what has happened.

"What the hell are you doing?" Marks yells out angrily, trying to lift Jess off him but failing miserably as she is taller and much stronger than him.

"Shh shh, just relax. It will all be over soon." Jess calmly while she gets the duct tape and places it over Mark's mouth.

"Ok Mark. I will give you a close look at the female body and you can experience the magic of the digestive system. Oh and milk doesn't agree with me, I probably should have said no to that milkshake." Jess explains all this while stripping off her clothes.

Mark is looking at Jess with both fear and admiration. There are a million thoughts rushing through his head as he stares at her now naked form in front of him. Jess squats herself above Mark's face. Her anus is a few centimeters from his nose which twitches as it gets a faint smell of previous farts and small specks of dried shit. He stares at the hole as it starts to pulsate. It looks like it's breathing when suddenly it opens wide and a strong wind is forced out with a loud 'BBBBRRRRRPPPPPPTTTTTTTT'. The smell hits Mark instantly and it makes him start to gag. He is so confused right now, after all these years spent admiring females farting, he never expected the real thing to be so horrible. His dreams have been shattered. Jess releases a 7 second SBD that snaps him back into reality. His eyes are starting to water as the smell of old dairy products intensifies.

Jess's legs are starting to get sore from squatting so she sits down her full weight in a reverse face-sitting position on Mark. She can feel his nose pushing against her anus. Jess feels a big one coming and starts to push hard to get it out. A truly terrible 15 second monster is unleashed directly into his nose. His whole body is shaking, he throws up in his mouth a little and tears are rolling down his face. A strong mix of egg, dairy and shit is all Mark is breathing. Jess holds her position for another 30 seconds and then moves off. Mark's nostrils start flaring as he desperately tries to inhale even the smallest amount of non-tainted air. As he is doing this though, Jess takes it upon herself to be even more cruel by quickly moving back on his face and letting out another 5 second 'PFFFFFFFFFFFTTTTTTT' as he is breathing deeply. He receives the full power of the fart and Jess turns her body around so her crotch is now covering his nose. With the smell of her farts trapped in the small space and with no air getting to him from being trapped inside her womanhood, Mark quickly passes out.

Jess gets off Mark and puts on her clothes. She takes off the cuffs and tape and places them in her bag. Jess makes sure to save the work they had done and then leaves to go home.

Mark's mum gets home and walks into his room after there was no response from knocking. She is hit with a strong smell that has been lingering in the air from when Jess was farting. Mark is still just lying on his bed either passed out or sleeping now so his mum opens a window to get some fresh air in and leaves the room.

The next morning at school Mark is on the way to his locker. When he is standing in front of it, he notices a foul smell coming through the slits on the front. He opens the door and on the middle shelf is a plate with a pile of actual shit on it with a note signed by Jess saying "Tell anyone about our fun and you will think that was pleasant experience once I'm through with punishing you."
