Very carefully

"Why are you taking your clothes off?" Cathy asked her sister as Nicole casually peeled off her outfit in the middle of the kitchen. Nicole's boobs seemed impossibly large, as did her butt. Sometimes Cathy wondered if she was even related to her super-curvy mother and sister, but then she remembered the long hours she'd put in at the gym and on dieting to get rid of the family "junk in the trunk", whereas Nicole and her mom spent their days cooking and eating.

"Well if I'm going to be the bowl I'll probably get messy!" Nicole said simply.

Cathy sighed. Cooking in female butts seemed so gross to her, even if they were perfectly clean through the wonders of modern enemas, and she did have to admit that the food tasted great when it had been stored in a lady's butt all day then prepared in one too. She sometimes put her own salads up her ass for a few hours to make them somewhat palatable. But that didn't mean she celebrated anal cooking with glee the way her shameless mother and sister did. Even among women this was nothing to be proud of.

Nicole was totally nude now, having a very light mocha skin tone and being shaved bare everywhere, at least. "I'll put the chicken in," their mother Susan said, taking a Bowel Bowl out of the drawer of kitchen gadgets. An essential tool for modern cooking, Susan inserted the Bowel Bowl tool in her daugher's anus gently, then delicately pressed it into Nicole's rectum.

"Does that hurt, honey?"

"No, feels fine mom!" Nicole was doubled over now with her butt in the air shamelessly. "Turn it on!"

Susan pressed the button and the automatic tool began to expand. It worked something like a butt plug without the plug, expanding to open up a woman's rectum to be used as a food prep bowl. Susan widened her daughter's anal ring to a moderate size, although it looked rather obscene to Cathy as she stared into her sister's bowels. Anal cooking wasn't for the faint of heart, but Nicole and Susan were wusses and seemed fine with it. Maybe Cathy was the weird one in this crazy world, she thought to herself as she looked away from her sister's gaping asshole.

Susan, who was naked under her apron, casually reached between her cheeks and pulled out her buttplug, the ordinary sort women use to keep food in their rectums these days. Then she sat on her daughter's ass and let the contents of her butt flow into Nicole, all those vegetables that had been inside their mother's ass all day. Susan wiggled and grunted, then when gravity wasn't enough she reached up her butt casually to scrape the last few out into her daughter's gaping butthole.

"Okay Cathy, add the chicken!" Susan said cheerfully.

Cathy grimaced. She slide her panties down and stepped out of them, then lifted her skirt just a little, not feeling like flashing her mother with her pussy. She reached between her butt cheeks and removed her food storage plug, then quickly sat on Nicole's ass the way her mother had. At least this butt chair was big and comfortable, Cathy thought to herself wryly.

Cathy felt the diced chicken cubes tumble out of her rectum into her sister's. She'd diced them this morning as there was no way she'd walk around all day with a whole chicken breast up her butt, although her mom probably would. She wiggled a bit to hopefully empty her rectum then stood up.

"That doesn't look like all of it," Susan said, shamelessly looking into her other daughter's gaping bowels where chicken chunks were atop the vegetables.

"Well it is," Cathy said defensively, "One pound of chicken. I did my part."

"I think there's more, let me check," Susan said cheerfully.

"Mom!" Cathy complained.

Susan dashed her hand with cooking spray. "Come on, this won't hurt a bit young lady, we have to have all our tasty chicken!"

Cathy sighed, but there was no going against her mother when she was in chef mode. Cathy leaned over the kitchen table and pulled up her skirt. She felt her mother's fingers penetrating her rectum, and then Susan was fisting her daughter's ass, looking for the last pieces of chicken. At least her mother knew how to do this without it hurting. Cathy tried to stay calm as her mother fisted her ass casually and Susan hummed pleasantly to herself. Finally she felt her mother's little hand pulling out of her rectum. "Look at all this chicken!" Susan said, having a handful from Cathy's butt.

"She was holding back on us!" Nicole teased.

"Shut up!" Cathy whined at her little sister.

Susan put the last of the chicken in then added the rest of the ingredients, mixing everything together for stir fry in her youngest daughter's gaping rectum with a wooden spoon. Cathy looked into her sister's bowels and saw the tasty mesh of ingredients filling up almost to the brim. Chicken, carrots, broccoli, peppers, ginger and garlic, now mixed with a soy sauce, Cathy had to admit it looked delicious in her sister's anal cavity.

Susan spooned the mixture in her daughter's butt bowl, then removed the bowl maker and sealed her daughter up with a special plug that would, combined with Nicole's body heat, cook their dinner inside the girl's ample rectum. They sat the table for a salad course, Nicole remaining shamelessly naked. The girl was shy around boys still, but with women she was very free.

"These salads were up my butt all day yesterday," their mother bragged.

"That's why they taste so good!" Nicole said, and their mother smiled.

Cathy took a bite of lettuce, knowing it had been in her mother's rectum. "Yeah, tastes good mom," she said sincerely.

They made chitchat over salads then the timer in Nicole's butt cooker went off.

"I'm done!" she said gleefully, her big boobs bouncing up and down. Cathy rolled her eyes.

Nicole squatted on the kitchen floor and pushed out piping out stir fry onto each lady's plate. Cathy watched as the chicken and veggies in sauce strained through her sister's anus and landed on her plate. Susan plugged her daughter's ass in case they wanted to go for seconds.

The ladies sat down and began eating. Cathy gobbled up stir fry prepared in her sister's anal cavity. Each chunk of chicken and bite of vegetable had been in her sister's bowels, cooked there in her sister's big butt. And it was delicious, Cathy had to admit. She couldn't get enough food from her sister's ass, even if it was so embarassing and silly.

"Anyone want what's left in my butt?" Nicole said eventually. Cathy looked down at her completely cleaned plate.
