Well, if she insists...

"Uh, I guess," Jessica said awkwardly.

"Thanks," Molly said, walking over and laying down on the floor where Jessica had just pooped.

"She's learning to eat shit properly, don't stare," Julia said to her sister as they got comfortable on the couch and watched the rest of the movie.

But the pretty young woman was eating Jessica's poop off the floor. Jessica couldn't not look. Julia scooped up a chunk of turd and pushed it into her mouth. Jessica could hear the older woman chewing her shit noisily. She scooped piece after piece of Jessica's shit into her mouth, retching occasionally, but managing to keep it down. There was something especially obscene about how Molly shoveled each bite of shit into her mouth, like she was eating popcorn. Jessica wondered if Molly even liked this or was just trying to fit in too and participate in the latest big trend for women. But she sure seemed enthusiastic as she **** down the pile of shit just as the movie was ending, then licked the last of the feces off the floor.

The women stood up and turned on the lights after the movie was over. Molly had a poop mustache and Jessica still had her own shit smeared over her face. Molly grabbed her tummy. "Oof, I ate that too fast," she said, going to the kitchen sink and casually puking up the feces she'd just ate.

"You've got a lot to learn about shit eating," Julia teased.

Molly leaned naked over the sink, heaving as the shit-vomit trickled out of her mouth and nose. "Shut up," she managed to say eventually, but was giggling at her misfortune. It was no big deal, just something she needed to get over with more practice. Cool girls these days could eat shit like it was candy and keep it down easily.

Molly washed her face off and turned to find her friend Julia licking the shit off her little sister's face. That was so hot. She watched excitedly as the sisters made out and Julia ate more and more of the shit-paste, until Jessica's face was clear of feces.

"I didn't know you guys lezzed with each other," Molly said warmly. Having lesbian sex with one's sister was also a cool fad, one that disgusted Jessica originally but after doing it a few times she had to admit to herself that she actually did find it pleasurable.

"Yeah of course, my sister isn't a total square," Julia said, hugging Jessica naked, pressing her tits against her 18-year-old sister's. The three girls wandered into Julia's bedroom and Molly lay against the bed's backboard, spreading her legs to masturbate as Jessica lay on her back with her sister atop her, making out passionately. She felt her sister's tongue probing her mouth and moaned softly.

Julia spun around and positioned her shaved pussy above her sister's mouth. They'd only been having sex for a few months but Jessica had gotten used to the kinky lesbian sex that was the norm lately, so she gave her sister's pisshole a casual lick then opened her mouth wide. Julia moaned softly and started to urinate into her sister's mouth. This was a standard part of every lesbian hookup these days but she was glad her sister was growing up and open to it.

Molly watched as big sister peed into little sister's mouth, filling it like a bowl with the golden liquid. "So hot," Molly said. She rubbed her own clit in slow circles as she started masturbating the lesbian ****.

Julia made herself stop pissing and heard Jessica gulping down the urine. Her sister was always such a prude with new kinks but now she was dyking out with her sister and drinking piss without much hesitation, she figured Jessica would be eating shit too in no time. It would be so hot to watch her sexy sister chewing shit and eating it.

Julia started licking her sister's pussy as she peed into her mouth. She loved the taboo of lesbian ****, having had sex with her mother and grandmother now, perversities she couldn't wait to see her little sister attempt. She pressed her tongue deep inside her sister's vaginal opening and unleashed the last of her piss into Jessica's mouth.

Jessica swallowed the last drops of her sister's urine then licked Julia's pisshole clean. Swallowing pee was easy compared to playing with shit, she even halfway liked it now. Julia then wasted no time pressing her pussy against her sister's face and Jessica started licking her clit. Julia returned the favor as the sisters locked into an incestuous 69.

"Yeah lick each other's clitties!" Molly said, masturbating shamelessly as she watched the show.

Jessica sucked on her big sister's swollen clit and shoved a finger deep inside Julia's vaginal opening.

"Fist me!" Julia screamed, then went back to licking Jessica's clit. Her big sister was so wet that Jessica could push in a second and third finger with ease. As she formed a fist it was harder to push it into Julia's bald cunt, but it still went into the hot hole without feeling like she was hurting her sister. Julia screamed in pleasure as she felt her sister's hand slide inside her. Jessica sucked hard on big sister's clit and Julia's body started to shake over her as she had a powerful orgasm.

Julia moaned into Jessica's clit then sucked it hard, bringing off her own sister with a skilled tongue. She collapsed naked on her sister as the two women rode out their orgasms with their hot bodies rubbing together.

Molly came too with a rapid flick of her fingers and the three women lay in bed for a while.

Eventually Jessica got up and squatted over her sister's tits, and the girls watched as she a turd started to poke out of her butthole. It came out slowly and just kept coming until its huge eight-inch length was revealed when it plopped onto the 18-year-olds boobs. Julia gasped in pleasure then presented her butthole to Molly, who casually gave her friend a filthy rimbjob, licking off all the shit and swallowing it down easily.

Jessica watched in mild embarrassment at the much more adventurous lesbianism and her nostrils were flooded with the disgusting smell of her sister's shit. After Jessica just let the smelly turd sit there on her breasts, Julia picked up her own turd casually. She played with her shit so easily now, Jessica noted.

"Want to try?" Julia said hopefully, dangling the turd hopefully over her little sister's lips, brushing it against them teasingly.

Jessica turned her head away. She hadn't even had the shots to make it safe to eat a lady's shit.

Julia frowned in disappointment, then raised the turd up to her pretty face and took a bit of her own shit, chewing it casually with her mouth wide-open as she munched the nasty paste.

"Stuff the rest up me," Molly said, casually spreading her legs, "I want to practice on it later."

Julia shrugged and pressed the turd against her friend's vaginal opening, the crammed the feces inside her friend like this was the most ordinary thing in the world. Jessica knew girls played with scat like this these days, but it was still shocking to see a pretty girl let her friend fill her pussy with shit.

"This is how big girls play with shit," Molly said to Jessica, and the girl felt hurt slightly.

The women made out for a while and Jessica smelled the shit on the others' breath, but wasn't offended. Then Molly went home and it was time for the sisters to get ready for bed. But before she went to sleep, Jessica got out her phone and made a doctor's appointment. She wasn't feeling sick, though, the appointment was to get her shots so she could start eating shit like a good modern woman.
