Shelby quenches her thirst for knowledge (and something else)

Shelby drove out of the school parking lot with Wei in the parking lot. She felt a strange kinship for this girl as both had conservative reputations and got strong grades, so they were "good girls" but both had just drank a belly full of urine then had their mouths **** by bully boys.

"Are you okay?" Wei asked considerately. The girl had a plain face, slightly pale, and long, jet black hair that was very straight.

"Sure," Shelby said, "I could have gotten out if I really wanted."

"Me too," Wei said. Shelby smiled in understanding.

"Have you had all your urine for today?" Shelby asked casually. Most girls at their high school drank urine for the health effects these days and it was fun to discuss the habit with a like-minded woman.

"Yes, thanks to that session," Wei said, "I'm also loaded up for tomorrow."

"But won't it get cold?" Shelby asked, driving to the highway that lead to the suburbs where both of them lived with their families. Cold urine lost nearly all of its nutritional value, everybody knew that.

"I keep it warm inside my body," Wei said, "It's called canteening."

"Canteening?" Shelby asked, "But where do you put it?"

"Inside me," Wei said awkwardly, "There are certain places."

"Oh!" Shelby said, blushing. "You let guys pee inside you?"

Wei blushed now, and Shelby liked that her friend was as shy as she was with this sort of thing. "Yes, it's degrading, but I don't have a brother and I don't want to drink my dad's urine. So I have to go ask my neighbor for enough to drink on the weekends, he's our age, but he always wants to do degrading things to me in exchange."

"I see," Shelby said, "Suddenly I'm glad I just have to let my annoying brother pee in my mouth to get my supply on Saturday and Sunday."

Wei smiled. "It's rough, this lifestyle... but it's worth it. I've lost 15 pounds."

"And your skin is beautiful," Shelby said, "And your hair even more so."

Wei beamed at the compliment, obviously taking pride in her appearance. "You look great too," she said to the class president. "I was letting guys pee in me before you came. That bathroom's full of perverts who like peeing in a girl's holes."

Shelby blushed but found herself aroused by the lengths Wei would go to for her urine. "Doesn't it leak out though?" she asked.

"No," Wei said, "I use special plugs. Turns me into a very nice bladder. I can hold almost 2 liters, I'll just drink some piss from strangers at the mall tomorrow and get my quota for the weekend."

"Whoa," Shelby said, amazed that such a shy girl would do these things for piss. But it was the way the world was heading, if she thought about. Shelby herself was doing things she never thought she would before, even letting her brother use her mouth as a urinal without batting an eyelash. "That's really cool Wei. I admire your commitment to this!"

Wei smiled and they made chitchat about their shared classes and the status of their college applications.

Eventually they got to Wei's subdivision, which wasn't too far from Shelby's, and parked in front of her house.

"Do you have enough urine for tonight?" Wei asked. Shelby had whined about how her brother wouldn't be available.

"Let me check," Shelby said, whipping out her phone and looking at the tracking app. "Shit, only 1950ml," Shelby said, realizing she was a few sips short. "I guess I could stop somewhere on the way home..." she said reluctantly. She'd never resorted to going in a public men's bathroom for a drink, but she knew many women did these days.

"No need," Wei said, "You can drink from me if you like. The plugs are very cool, you can attach a straw for convenient drinking. If you don't mind drinking urine that's been in my body."

Shelby shivered. The idea of drinking urine that had been peed into Wei's holes and stored there behind a plug was so sick, but she also found it arousing in a way. "Uh I guess," she said, "If you don't mind. It's a lot to ask."

"It's no problem, I owe you for the ride anyway," Wei said with a cheerful smile, "Would you like to drink from my vagina, or ass?"

Shelby shivered again, very arroused now. "V-vagina," she said.

"Don't worry," Wei said, "It's just something we have to do these days as women. I'd never go back to how ugly I was before I started the urine diet."

"Me either," Shelby admitted.

Wei fished around in her backpack and produced a long, somewhat fat and totally clear plastic straw, then reached up her skirt. The Chinese girl gasped as she touched between her legs to attach the straw. Shelby couldn't help looking to see a strange black apparatus protruding slightly from the girl's vaginal opening, her waxed-smooth labia skin so beautifully pale.

Shelby took the straw and inserted it in her lips, then started to suck. She watched yellow fluid begin its long journey trough the snaking straw. She was sucking urine out of Wei's vagina, this was so wild. She noticed there was a flow meter set to 0ml, and gave a powerful suck. Pleasingly hot urine from an unknown boy at school landed on her tongue, Shelby tasted the glorious fluid then swallowed. The piss stayed perfectly hot inside Wei's vagina, it was full of all its wonderful nourishment.

Shelby sucked more urine out of her friend's vagina, hesitantly making herself stop when the flow meter read 52ml. She swished the nasty pee around in her mouth then swallowed as Wei watched. Wei grabbed the straw and had a sip herself, casually drinking from her own vagina, then blew out into the straw to put the rest of the urine back up inside her rather than leave any in the straw. Then she reached and detached the straw.

"God that feels good," Wei said, blushing, "It's like fucking myself with urine when I push it back in."

"Whoa," Shelby said, feeling wet with arousal. God, this was supposed to be a nasty but necessary diet, not a kinky turn-on, Shelby chided herself.

Wei kept blushing. "Well thanks for the ride," she said. She leaned in and kissed Shelby on the lips, and both girls smelled urine on the other's breaths.

"No problem," Shelby said, "Come over sometime. You can drink my brother's pee and we can, you know, explore. If you want."

"I'd like that, Shelby," Wei said with a smile, "Well, goodbye for now."

Shelby watched as the perverted but respectable girl walked with a bounce in her step as she went into her house.

Shelby looked at her app. 2002ml of urine consumed today... but she was still thirsty.
