Those were Evelyn's rugby days. Lily normally arrived home two hours before Evelyn and got dinner ready. Now, that was Julia's time. The first day was Thursday. As directed, Lily waited on the steps outside her school. Julia arrived from cheerleading practice around four. Lily gathered her belongings and hurried to her. "Hiya," Julia said. "Hi." "We gotta move fast. My house is in the opposite direction. Wanna run?" "Sure." They jogged half a mile to Julia's home. Neither of her parents' cars were in the building lot. Good. Her parents were due back until after Lily would leave, but every now and then one stayed home. "Here we are." Julia fetched her keys. "Are you looking forward to this?" "No." Julia stared at her, then remembered. "Ohh, right. You're not allowed to lie to me. That's okay. I'm here to make you enjoy this stuff. We're gonna have fun." She opened the door and ushered Lily in. "I'm not going to do any of that master-slave punishing stuff. I'm not into that." "But," Julia said as they headed upstairs, "You still need to obey my orders. Evelyn wants me to report back for every session. She wants to know if you're disobeying me. Cool?" "Cool." In her bedroom, Julia rolled her carpet aside and fetched a plastic tarp, which Lily helped her lay out over the floor. Once done, Julia closed the door and sat in the middle of the tarp. "Join me," she said. Lily set her book bag aside and sat before Julia. "So. Today I thought we'd just talk. Maybe we'll do something dirty later if we're up to it. That sound cool?" "Yeah," Lily replied. "Good. So, what's the grossest stuff you can handle?" "I sometimes clean people's cocks after they do me in the ass. That's usually the most I ever do." "That's all? What's the grossest thing you've ever done?" "A couple months ago, I was fisting a woman's ass. My hand got covered in her poop, and she made me lick it clean with her. I threw up. Evelyn caned me pretty hard when we got home." "Does she cane you a lot?" "Yeah, but that time was really hard. I've tried a couple more times since then, but I always throw up. We haven't tried for a while. Evelyn sort of dropped it. " "Then I come along and convince her you should do this more. You probably hate me, don't you?" "I don't hate you. I want to be able to do to this." "Really? Why?" "Evelyn wants me to be able to do that kind of stuff. She hasn't booked any more shows with that other woman because she doesn't want that woman upstaging us again." "This woman eats poop too?" "Yeah. She's better at it." "And she took a fist up her ass? Who is she? She sounds like my kind of girl." "I'm not allowed to tell you. Sorry." "That's fine. Do you think I'll get to meet her sometime?" "Maybe." "Does this woman know that Evelyn gave you to me to train?" "I think so. This woman kept offering to train me herself, but Evelyn doesn't want that. It's a pride thing. Evelyn said she was instead going to sell me to the sickest pervert she could find to break me of my squeamishness. She'd buy me back after he'd force fed me unspeakable amounts of poop and I could eat it on my own.." "That sounds fucking hot." Lily smiled. "I guess you're going to be the pervert." "I wonder why she doesn't train you herself. I'm not going to be nearly as strict with you as she would be." "She doesn't likes doing this kind of stuff herself. She mostly wants me to do it so she can give me to more depraved clients. And so this other woman doesn't upstage me again. I was really surprised when she pooped for you." "I'm glad she did. I think the sight of her pooping is hot. I would honestly love nothing else than for her to use me as her toilet every day." "Really?" asked Lily. "You'd want that?" "Have you _seen_ your sister? You're lucky you get to be her slave." "Yeah, but isn't it still gross?" "Gross? Yeah. But that's kind of what makes it hot. It's taboo, and dirty. Everybody likes that to some level. People like anal sex, or panty sniffing, or having sex when they're all sweaty. I'm just like that, but a thousand times more about the dirtiness. I'll do things that are gross just because they're gross, and it'll turn me on. Once I ate poop out of a toilet without knowing who's it was. "Really?" "Yeah. Couple years ago my parents took me to the skating rink. I went to the bathroom and found out that the toilet was broken, but several people had peed in it, and at the bottom was a half-dissolved lump of poop. I stood there for, like, an hour until I worked up the nerve to reach into the toilet and take the poop out. I licked and sucked it. It was so mushy that it dribbled down my arm." "And you didn't throw up?" "Oh, I threw up all over the place. I made the bathroom waaay messier." "But you still enjoyed it?" "God, yes! Even as I threw up I was rubbing myself. And I've masturbated so many times thinking back on it." "Why?" "Because I'm a sick puppy, that's why." "And that's what you want me to become?" "Well, my goal is to help you embrace the dirtiness of sex, and maybe help you appreciate your sister more. You think you can do that?" "Yeah. Think so. I was kind of hoping you'd help me with other clients too.' "Really? You want that?" "It'll make Evelyn happier." "Wow. Aren't you the dedicated sister. All the more fun for me." Julia hopped onto all fours. "Let's do something sexy. Shall we?" Lily nodded. "Still feeling nervous?" Again Lily nodded. Julia leaned forward and kissed her. Their tongues played in each other's mouths as Julia pushed Lily onto her back and climbed on top of her. She peeled off the top of her cheerleading uniform, unclasped her bra, then lowered onto Lily. Entwined with each other, Julia pulled Lily's clothes off one by one until the girl was naked beneath her. She made a trail of kisses down Lily's body to her pussy, and slipped her tongue inside Lily's slit. Lily writhed in pleasure. Julia didn't let up until Lily was whimpering. Stopping, she climbed up and hugged Lily close. Their breasts pressed together. "Feeling better?" Lily nodded against her shoulder. "Then how about we step things up. Let's play the game: _who's going to eat who's poop_." "I'm going to eat yours?" "Wrong!" Confused, Lily frowned. "What?" asked Julia. "You thought I was going to throw you into the deep end? I'm here to show you how to _enjoy_ it. So we're starting off slow." She smiled. "And maaaybe I'm doing this whole thing just because I want to have fun with you." Lily smiled. Julia rolled onto her back and motioned to Lily to get over her. Lily knelt over Julia's face, positioned so she could look Julia in the eyes. Julia licked Lily's asshole like a dog. Lily looked unsure of herself. "Yes?" asked Julia. "I um... I have to pee first." "Oh right." Julia fastened her mouth over Lily's urethra. It took Lily nearly a minute before she could relax enough to let loose. When it came, the stream was a gentle dribble which Julia easily drank down. When she finished, Julia refastened her mouth to Lily's anus. For nearly two minute, all Lily did was flex her sphincter in and out. "I can't," said Lily. "But you do have to, right? I told you save up." "I do. I'm just embarrassed." "Don't be. You're just like your sister: beautiful and sexy with looks most girls would kill for. I can't believe how lucky I am that I found you two girls. Millions of men and women who would pay money to be where I am. They'd watch you pooping for their porn. Take your time. The whole reason we're here is to help get you comfortable with all this." Lily was blushing. "Does it help when I do this?" Julia ran her tongue along Lily's rim, then stabbed into her hole. "No." "Okay. I'll stop. Just take your time." And Lily did. It took her nearly five minutes of her anus pushing in and out before finally it widened. A single nugget of poop fell into Julia's waiting mouth, and then the anus closed back up. Julia mashed the piece with her tongue, allowing the flavor to fill her mouth. She lifted her own butt off the floor to pull off her cheerleading skirt, then rubbed herself as she enjoyed the morsel. With her mouth still coated, she looked up at Lily. "Any more." Lily nodded and scrunched up her face. Her expression was adorable. Watching Lily, Julia nearly missed Lily's hole opening back up. She opened her mouth just in time for a torrent to pour out. An enormous length of creamy shit poured out of Lily, overflowing Julia's mouth instantly. Lily's bladder released again and piss shot into Julia's eyes and soaked her hair. Julia squealed. Lily immediately clamped her bladder and colon. "Oh my God! I'm sorry." She clambered off Julia. Julia propped up on her elbows and blinked the urine out of her eyes. The shit that had piled on top of her mouth fell onto her breasts. With her mouth stuffed, she spent a minute slowly chewing the mass and swallowing it down bit by bit. She finally swallowed the last in her mouth. "That was unexpected." She swiped her finger along her cheeks to collect any remaining shit. "I am so sorry." "No biggie. I'll just jump in the shower after we're done, but you're going to have to work on your pelvic floor. You know what I mean?" Lily shook her head. "Your muscles. You have no control over them. And not just getting over nervousness. You need to learn how to poop while holding your bladder." "Is that even possible?" "Yeah. It's two different sets of muscles. I can do it. And your clients will like it if you can to. I'll teach you some exercises you can do on your own time. Otherwise, we're done for today." Julia picked a piece of shit from her breasts and popped it in her mouth. "That's it?" "Yeah. I'm not going to make you do anything else... unless you want to." Hesitating, Lily nodded. "Then why don't you come give me a kiss." Lily crawled forward, bringing her mouth inches from Julia's. She paused at the smell of Julia's breath, but slowly, she closed the distance. Their lips met. Any reservations Lily had melted away. They kissed passionately. Julia entwined her hands in Lily's hair. They pulled away breathless and stared into each other's eyes. "I would keep you for myself," said Julia, "if you weren't already your sister's" Lily smiled. Her gaze went from Julia to the mound of shit on her breasts. Julia followed her gaze. She picked up a piece and popped it in her mouth, then stared at Lily with daring eyes. Lily kissed her again. After entwining their tongues, Julia pushed the lump into Lily's mouth. Lily recoiled, but only briefly. She pressed her lips back and returned the lump to Julia, who chewed and swallowed it. Lily kissed a line down Julia's chin and neck to the pile remaining on her breast. She lapped up another clump and pressed her mouth again to Julia's. They passed this one back and forth, letting it dissolve. Julia smeared the remainder of the pile over her chest. When Lily lowered down again, she licked Julia's breasts clean of the shit. Whenever she succeeded in cleaning one boob, she'd move to the other, and Julia would resmear the clean one with her dirty hand. Back and forth Lily went, until finally she gagged. She tried to continue, but Julia stopped her. She pulled Lily to the ground and interlocked legs with her. They ground their cunts together until both girls shuddered in orgasm. Afterward, they lay breathless on the plastic tarp. "How do you feel?" asked Julia. "Sick to my stomach," said Lily. "But still a little turned on." "A perfect way to end it. Let's clean up and get you home.
