Chapter Text
Phineas had gone to a Yo-Yo convention but unfortunately Ferb had to go to a British Four-Flags barbecue in honor of Guy Fawkes Day. Technically, that had been Friday, and it was now Saturday, but there was no way around it, without being in two places at once, and Phineas had neither a Time-Turner nor a Byzantium Worm that an online friend, Leonard the Wizard, had mentioned.
Of course, Time-Turners didn’t work in real life. This wasn’t Harry Potter. Phineas kind of had a celeb crush on the girl playing Hermione in the new TV show. She had rocked that first season.
Anyhow, he went into the living room where Stacy Hirano was seated on the couch.
“Where’s Candace?” Phineas asked.
“Waiting for her,” Stacy said. She was such an adorable Japanese chick. In some ways, it was like Phineas had a real life anime girl that he saw…many days of the year. He wasn’t sure he should tell her that, though. She might find it silly.
But she was cute, darling, sweet…and definitely fun to be around, or at least in theory. Of course, thinking that about your sister’s friend could be weird, but…to be frank, Phineas hadn’t spent much time with Stacy at all, and certainly not without Ferb around.
“Might if I sit here?” he asked.
“Not at all,” Stacy said.
Phineas hopped onto the couch.
He showed Stacy a fun game called Hippo Solitaire he had gotten addicted to on her phone.
She was having fun engaging with that, lassoing hippos as a spoonbill in the game, when she felt something major in her butt…
“Something wrong, Stacy?”
“Um, I kind of need the bathroom.”
“Well, by all means, go.”
Stacy got up and made a couple of steps, when she fell back on the couch where the arm was.
“What is it?”
“I can’t make it,” Stacy said. “About…to poop…in panties.”
“That can’t be good,” Phineas said.
“Yeah, it’ll be awful and Candace might hate me for it.”
“That would stink,” Phineas said.
“Yes, exactly, that’s why she’d hate me.”
“Well, maybe I can help.”
“How is that?” Stacy said, squeezing the arm of the sofa. She groaned, it felt like if she didn’t unclench her butt in seven seconds, a tsunami of feces would pour out of her.”
“You can use me as a toilet,” Phineas suggested.
“What?”
“Yeah, I can just lie on the couch and you sit over my mouth.”
“That sounds…super weird.”
Stacy’s phone dinged, she picked it up. “Oh no, Candace says she’ll be here in eight minutes!”
“It’s the only way, sit on me!”
Stacy knew Phineas was right, she had to just jump in and not worry about it, so her skirt and panties went down…
With butt over Phineas’ open mouth, she let loose the strands of scat.
Her butt made noises as it emitted these strands.
They smelled…and tasted…horrendous. But Phineas felt so lucky he had gotten to have a girl use him as a toilet, absolutely fabulous!
It actually tasted worse than he fantasized about. But that made him excited regardless. The only thing that would make this better would be if Stacy forced him to take it, but he knew that portion of the fantasy was so unlikely to see actualized.
So Stacy kept dumping in him, filling most of his mouth.
It was only when she no longer needed to release any gross brown matter that she registered the feel of his triangular nose against her posterior. It felt…kind of nice.
“Sorry about this, Phineas,” she said, sheepishly.
He ate through the poop in his mouth and swallowed the last of it, she was about to move off…
“Wait, you can’t meet with Candace without wiping your booty!”
“You’re right, should go grab some toilet paper.”
She went into Candace’s bathroom but came back shortly, agitated.
“What is it?” Phineas inquired, sitting up now.
“There’s no toilet paper in there! Now feeding you was a waste, she’ll still smell me!”
“Relax,” Phineas said. He actually was bugged by her calling what she had just done to him a “waste.” “I have a way to clean you out.”
“How?”
“Let me be your toilet paper.”
“What?” she asked, blinking.
“My tongue can clean you out.”
“I can’t ask you to do that.”
“It’s no big deal,” he said.
“Okay, if you’re sure…”
And once more, her beautiful tan booty sailed toward his face…
And his tongue entered her, scraping wet poop flecks away.
He kept cleaning her out until they heard Candace’s car pull in the driveway.
“Yikes,” Stacy said. She pulled her panties and skirt up.
She couldn’t say that having Phineas’ tongue in her bothered her. In fact, it felt quite nice, but she felt a bit spooked that he felt the need to do that, and hoped he wasn’t going to be agitated around her now that had been done.
Candace opened the door. “Stacy, if you’d please go grab the other bag from my car.”
“Sure,” Stacy said, going out to take it, Candace carried a huge Wingstop sized bag, loaded with stuff, toward her bedroom. She had tossed her car keys at Stacy on the Japanese girl’s way out so she could lock her car up.
“Sorry about having to do that to you, Phineas,” she said, when she came back in.
“Don’t apologize for it, was an experience,” he said.
“A stinky experience,” she said, wrinkling her nose.
“Yo, Stacy, you back yet? We needed to unpack these.”
“Coming!” Stacy called, heading toward the stairs and going up.
She had no clue that Phineas was eager to repeat that experience and fathoming a method to convince her it’d be all right to do that in him again…
