On the plane with Paul

Martha had been in Britain on business and was looking forward to getting home to the States. She was annoyed that her company hadn't paid for her to travel business class, but she settled into her seat in economy and strapped in for take-off. Her seat was the middle of a row of three. To her right sat a pretty young woman whose first action upon sitting down was to take a selfie and post it to Instagram. The seat to her left was vacant for a while, until a geeky looking man boarded and found his way to that seat.

With the doors locked and the safety demonstration completed, the plane was taxiing to the runway when the girl to Martha's right decided to strike up a conversation.

"Hi, I'm Barbara," she started chirpily, "but my friends call me Barbie. I'm an influencer."

Martha couldn't help but roll her eyes, but if her business career had taught her anything about networking, it was that any contact was a potentially useful contact, so she **** a smile and introduced herself.

"Hello over there," called Barbie to Paul. "I'm..."

"I heard," said Paul with a smile, "I'm Paul and I'm a scientist."

"Lovely to meet you, Paul," beamed Barbie.

"So, what field of science do you work in?" enquired Martha.

"Mainly biology, pharmaceuticals, that kind of thing," replied Paul, squeezing out what must have been his tenth fart since he boarded the plane, pleased that the engine noise was hiding the sound for the most part and that so far nobody had noticed - or at least, commented on - the smell. Gaining in confidence, he pushed the next one out. It was loud. Loud enough for Martha to hear.

"Oh, er, pardon me," he apologised.

Martha nodded politely - until the stench hit her nostrils.

"God, what have you been eating?!" she asked.

"Ewwww" exclaimed Barbie as she too detected the pong. Paul just grinned and watched the pair of them closely.

At this point, the plane reached the runway and took off. Martha felt the familiar sensation of the plane leaving the ground, and shuffled in her seat a little as something felt a bit uncomfortable. She had been sure to wear loose, comfortable clothing for the flight but her top was now feeling a bit tight.

Paul farted again, and Martha smelt it almost instantly, but this time she found the odour surprisingly pleasant. So pleasant, in fact, that it sent a wave of pleasure through her body, a tingling sensation that ran down her back, making her nipples hard on the way past and lingering in her vagina. She took another, deeper, breath, and felt the same sensation again.

"Mmmm, Paul, what have you been eating?" asked Barbie to Martha's right, beaming over at the windy man to her left. Paul didn't answer, but instead just farted again, watching the two women to his right. Barbie was wearing a crop top which had been fairly tight against her chest to begin with, but now the fabric was positively stretching as her boobs proceeded to grow in size, already approaching nearly double their original volume. He noticed that Martha leaned slightly towards him to breathe in as much of his fart as she could.

This time the wave of pleasure that coursed through her body **** her to let out a little whimper as her pussy pulsed rhythmically, leaking fluid onto her panties. She looked over at Barbie's crotch and saw a wet patch on her pink shorts. Barbie unashamedly put her hand on there and gave a little rub, making herself moan in pleasure. Martha looked up at Barbie's face and their eyes met, looking deeply at each other.

"Has anyone told you you're beautiful, Martha?" asked Barbie, and leaned towards her. Martha didn't have time to think, her body just seemed to respond of its own accord, leaning in so that their lips met and parted. As they kissed, Martha's pussy exploded in a gush of pleasure and she had to break away, gasping wide-eyed and open-mouthed at what was happening to her body. Her hand grasped at her now massive tits in astonishment at how big they were, but the contact with her nipples immediately sent another orgasm through her body and she, too, found herself grasping her pussy, fingering herself through her wet clothes.

She looked over at Paul and she felt as if she had never seen a more beautiful person in all the world. In that moment, finding a way to get his dick into her pussy seemed more important than anything. And then she felt a pressure in her bowels, a strong urge to fart, the pressure building by the second, and so fart she did. The vibrations sent more waves or pleasure through her pussy and she came for the third time in two minutes.

A voice inside her head was telling her this wasn't normal, this wasn't right. She had to find out what was going on. All this started with Paul's farts so he must know something about it. She had to ask him.

"I, I need to ask you," she started, blushing as their eyes met, the question forming in her mind. But a different question tumbled out of her mouth. "Do you like my titties? I'm growing them for you. Would you like to see them? Perhaps I could wrap them around your big, hard cock?"

"They're lovely titties, Martha," replied Paul. "Let's have a little feel of them," and he reached over to fondle Martha's breasts as Barbie farted and came loudly.

"Excuse me, miss," interrupted the air stewardess who had come over to see what the commotion was all about, "you really can't be doing that here, you'll disturb all the other p... what is that smell? It's disgu... it's dis... oh, it's gorgeous!"

"It is, isn't it," replied Barbie, "and it's coming from my tight little ass."

"Oh, I... I need to investigate further, we can't have odours filling the cabin," said the stewardess, kneeling down and pulling Barbies legs open. She pushed her face into Barbie's wet shorts as Barbie farted again, holding the stewardess's head in place as she breathed deeply and then started licking the outside of Barbie's shorts.

"I'm sorry, miss, I need to investigate more thoroughly," she said, and moved to pull Barbies shorts down. Barbie helped her, exposing her sopping wet pussy, which the stewardess eagerly set to work on licking out.
