The man looked upon the woman with a grin. Not only were the bars increasing their appetites, but they were altering their digestion, their chemical balance. Due to the weight they retained, they rarely needed to expel waste. And in their altered forms, the remaining waste was converted to sweat and gas emissions. Thus, they would never need to use a toilet again. Additionally, they now secreted unusually potent pheromones, ones that would stimulate those around them, bringing others into their fold and strengthening the bond between them.
As Sarah reached for the last piece of pizza, she felt another greasy hand on hers. Her eyes met Karyn's and they giggled momentarily at their little standoff. "That's all yours, cutie," her friend said with a wink and a low rumbling fart. Karyn had become the gassiest of the three, Sarah noted. Not that she minded. It was a sweet, pleasing scent that blended well with her natural earthy musk. It was soothing in fact, gave her a tingling sensation as she breathed it in. She looked at her friend's gigantic breasts hanging over the remains of her small girl's tee. Soon she would completely outgrow her clothes, and her gorgeous glistening body would forever be on display. Sarah blushed at the thought as she grabbed from a plate of savory croissants that had just materialized. She wasn't too far off herself, she thought. Her shirt was now riding above her massive gut, looking more like a bra. Her skirt was ready to snap off at any moment, and did nothing to hide her huge rippling ass. Before long she would need a chair for each cheek like her mother, unless they eventually opted to just sit on the ground.
She looked over at Karyn who was fishing some mashed potatoes from between the cavern of her breasts. She glanced up at Sarah mischievously. "Looks like I've made a mess," she said sucking it off her plump fingers. "Want to give me a hand?"
Sarah watched transfixed as Karyn then grabbed a pitcher of ice water and poured it over her chest, soaking the remains of her shirt and rolling down her gut that now hung down from the chair. "Maybe next time," she said with another wink. Sarah chewed into her ham and cheese croissant and let loose a fart of her own.
Susan sniffed the air approvingly, "Oh that was wonderful, darling," she said between bites of cheesecake. She was barely recognizable as the uptight fashion model she had been earlier that day, now a complacent 450 pound naked behemoth, covered in sweat and foodstuff.
"Thank you mother," she said and grabbed a handful of cheesecake. Her mother grunted and pushed the rest of it to her as she grabbed a fresh apple pie.
"Mom, doesn't Karyn have a great body?"
"Oh yes, dear. The two of you have grown into such beautiful young women. I'm so proud of you both." Susan punctuated her statement with a loud fart.
"Thanks Miss M," Karyn said, taking in the woman's form as she kept eating. "You're so much hotter than you were as a model."
"Oh thank you, Karyn, that's very nice of you." Had she been a model, Susan thought. There was some vague memory of that, perhaps.
"And I love looking at your breasts." Karyn was massaging her belly with one hand. "I bet they feel great to touch."
"Oh your friend is such the charmer," Susan turned to her daughter with a giggle. And another fart.
Without a thought, Sarah clutched a handful of her mother's rippling breast flesh. "Yeah they do feel nice. Even better than when I used to suck on 'em." Susan gave a fond smile to this, but kept eating.
"Better find out for sure," Karyn chuckled as her hand trailed to the under region of her stomach. Sarah immediately clamped her mouth down on her mother's plump brown nipple, teasing it with her tongue and teeth.
"Oh thank you, dear. That feels lovely." Susan began stroking her daughter's side, just as her shirt finally gave up the fight and snapped off her gut. Susan suddenly felt another piece of pie get shoved in her mouth, and a mouth latch onto her other breast. She moaned through bites as her free hand began to search for her dripping vagina underneath her apron of fat. That failing, she began grinding into the chair, clutching a breast of each girl. A chorus of carnal pleasure and flatulence filled the room as the man kept watching from the window, eagerly anticipating subsequent developments.
