There were four shops Vera and Tess Bashear, who were sisters, hoped to visit at the mall that late spring afternoon, but after browsing through the second one and emerging empty-handed, they decided they'd had enough and needed to get home as quickly as possible. At least Vera did. She enfolded her arm in Tess's and led her toward the exit.
"It's like the planets are lining up all of a sudden for some celestial event and there'll be no stopping it," murmured Vera somewhat cryptically into her sister's ear. A few heads turned their way as they passed through the crowd, which was not unusual seeing how attractive they both were. Vera was 21 years old and Tess had just turned 18 a few months earlier. Both girls were medium height and on the petite side, both sported shoulder-length hair, Vera's blonde, Tess's chestnut, and both were perfectly shapely in all the right places. But those features were just icing on the cake compared to their gorgeous faces, which were the reason most of those heads were turning.
"I wish I knew what you were talking about," Tess responded. Suddenly Vera stopped walking, almost causing Tess to stumble, and turned to face the shop window they were in front of.
"Stand close," Vera whispered.
Tess positioned herself as close to Vera as she could without stepping on her. "This is a men's shoe store," she pointed out. "Why the fuck are we looking..." Then she stopped talking and leaned even closer into her sister's body. After a few seconds she spoke again softly, "Oh, fuck, Vera, that smell is amazing! Jeezus, are you shitting your panties?"
"Vera giggled and said, "No, but pretty fucking nearly. I've got a thong on so it would be all over the floor if I did."
"Want to go to the ladies' room?"
"Fuck no! This is why I want to leave. Let's go home so we can do something much more interesting than visit the ladies' room."
They made their way to Vera's car and got in. Immediately Vera let out a fart that rumbled on for several seconds and filled the car with its heavy acrid odor. This caused Tess to howl hysterically, "Shit, girl, you're just a disgusting bitch, aren't you!" She took a deep whiff and added, "Come on, slut, do it again!"

"What's wrong, girl?" Vera asked her sister. Both were lying naked on Vera's bed, Tess straddling her sister's tits. There were a couple of fluffy bath towels under Vera's upper body. "You told me as we got out of the car that you really had to pee. You begged me to hold off and let you go first. Well, I'm waiting."
"I know," Tess replied, looking down into Vera's face as she fingered her shaved pussy gently hoping it might stimulate her to urinate. "The urge just disappeared, I don't know why. Maybe we should go back out in the car again."
"Let me lick your pussy some more, that might help." Tess moved forward a few inches and lowered her pussy onto her sister's lips. Vera circled her tongue all around the opening to her pussy, nibbling the lips, before going deeper inside. She was very wet and tasted as familiar as ever -- a very slight hint of tangy saltiness, but hardly discernable.
"Ah, that feels so good, Vera, I love it. But hold still for a second, I think I feel something..." She dribbled a few drops of piss into Vera's mouth and then a steady flow began, not a torrent, but a gentle cascade of yellow nectar. The rate was just right for Vera to keep up with and swallow without choking. Having her sister pee on her, especially in her mouth, always gave her a tremendous thrill. She reached for her cunt with her right hand and touched herself, her finger plunging inside her drenched opening. After three swallows she let most of the rest dribble down her chin and across her cheeks, and when Tess stopped going for brief moments, she squirted mouthfuls onto her pussy and belly.
When the golden shower tapered off and they were thoroughly drenched, Tess said, "Can you still hold it a bit longer, Vee? Now that I've given you my champagne cocktail, I need to shit really bad. You don't mind, do you?"
"No, I don't mind, as long as there aren't any more disappearing urges," she answered.
"I'm sure that won't happen, I can feel it begin sliding down already."
"I hope it's a lot, a real lot," Vera declared.
"We'll just have to see, won't we."
She got to her knees and, facing backwards, arranged her rear end over Vera's tits while straddling her. Since Vera had introduced this fetish to Tess, with the help of their parents, shortly after Tess's 18th birthday, it was something both looked forward to engaging in together more than anything. The heights of sexual gratification they reached while covering each other in their shit and piss were incredible.
Tess massaged her sphincter with her finger tips and then strained a bit until a semi-soft log began to crackle from her ass and onto her sister's tits covering them. Another turd emerged and piled on top of the first. The odor of fresh shit made itself known and then exploded as Vera started to wipe the steaming heap of feces across her tits and belly to her pussy.
"How's that, Sis. Good?" Tess said, turning around.
"Mmm," Vera hummed joyfully. "Excellent job. It smells wonderful, too! Come on, get your hands in here."
Tess gazed down at Vera, her hands busy spreading her treasure all over herself with great pleasure. "That does look like a nice pile, if I say so myself." She buried her hands in the mess, aiming for Vera's tits, and smeared them lovingly with shit. When they were totally covered she bent down and licked each one, coating her tongue with several streaks of semi-bitter goodness. She sucked them harder, especially her nipples, until her mouth was half-filled with her fudge and then stretched her body onto Vera's and kissed her. Their tongues danced together, pushing the shit between their mouths. Before long much of the front of their bodies was smeared with poop.
"Well, we're off to a good start," noted Tess, admiring their handiwork. "Now, you can finally go after I made you wait so long."
Throwing her arms around her sister, Vera chimed, "It feels so wonderful, doesn't it, Tess? Don't you just love the feel of all that shit on your skin -- so dirty and nasty and wild! It just blows my mind!"
"Yeah," agreed Tess, sitting up again and palming her sister's nipples before smearing a handful of poop around her neck and shoulders. "I feel like I'm this totally disgusting slut and I love it absolutely. My insides go into fits and feel like they want to explode."
Vera smiled. "I always knew I was a filthy girl and glad you are, too. It's so much fun when we do this together."
Tess moved up to Vera's face and smeared a long glob on her forehead and even her ears, while Tess concentrated on coating her belly and pussy. "I guess we're a complete total one-hundred percent for sure scat family now, through and through. Daddy and Mom must be thrilled."
