It was around 10in the morning when Angie opened her eyes, the sun was beaming in through the window and the room was warm. She stretched her arms and rolled onto her back "OH SHIT!" she thought as she nearly jumped out of bed. Her brother Mark was still laying in her bed next to her, she felt her body and she was wearing a nightgown. She lifted the covers slightly to see, yes, her brother was wearing boxers and a tee shirt. "ok, so nothing happened" she thought to herself. Marks eyes opened and he looked at his sister.

"oh crap! I was going to just lay here for a bit in case you woke up. I meant to go to my own room, I'm sorry Ang!"

"no, don't be sorry, that is really sweet of you. Thank you for staying with me and taking care of me. I hope you don't think less of me, or worse, I hope you aren't grossed out by me after last night...."

"I could never be grossed out, you're the sexiest, um, I mean you're the most beautiful girl I know. You're my sister I will always love you"

"You're sweet for saying that, but I see how you look at Jules, I know you think SHE is the sexiest" Ang said teasingly as Mark began to blush. "did I mention since mom and dad are away she's coming over tonight?"

"uh, no, you didn't mention that"

"Is that ok? Do you have plans?"

"No no, it's cool, I'll uh, be around. I think I'm gonna go get dressed and figure out what to do with the day"

Mark rolled out of bed and Ang could see his boner pushing against his boxers, it made her grin. Mark left the room and Ang rolled over to grab her phone to text Julia.

`hey Jules, what time do u think ur gonna come over'

`I'm thinking around 5, cool?'

`yea, sounds good I'll see ya then hun'

`ttyl'

-later that day-

It was just after 5 when Julia arrived at Angies place. The girls greeted each other with a hug and Angie took Julias coat and hung it up. Before heading to the to decided what they would have for dinner, the girls ran upstairs and changed into their PJ's. Angie always loved watching her friend change, Julia is about 5'3", she wasn't more than 110 lbs soaking wet, she has a tiny little waste, a firm ass to die for, and a decent C cup for her size. Once they were in their PJ's they headed back downstairs to the kitchen where they settled on a frozen pizza. Angie put the food in the oven and they went to the living room to watch some TV while the food cooked.

Angie flopped herself onto the big leather sectional and pulled a blanket up over herself, she was always cold. Julia curled up in the recliner next to the couch in the corner of the room.

"do your parents still get the hustler channel Ang?"

"yea, it's so funny they think I couldn't figure out the parental controls on the PVR haha, you wanna watch some?"

"Yea, you good with that?"

"Of course, it'll be entertaining while we wait for the food"

Jules flipped to the Hustler HD channel, on the screen was a girl on girl scene, Ang & Jules favorite.

"Nice, I love some nice girly porn" Ang said

As the girls watched they both became aroused, both girls felt themselves getting wet. Before long Julia's hand made its way under her PJ pants and started rubbing her clit through her panties. Angie saw her friends hand down her pants and this turned her on even more, she spread her legs under the blanket and pulled her PJ's and undies down to her knees. Ang always preferred insertion over clit stimulation and she quickly slipped two fingers into her moist twat. Julia giggled quietly as she saw what her friend was doing.

"shh, I'm trying to watch the porn" Ang said to her friend.

Giggling some more Julia let out a little, but audible fart.

"geeze, you're sure making it hard to concentrate over here!"

"Aw, am I distracting you, I'm soooo sorry" and they both giggled causing Julia to let out another fart.

Just then Mark walked into the room

"what's so funny in here?"

Both girls jumped, Ang had completely forgotten her brother was even home.

"MARK! what are you doing, geeze can't we get a little privacy?" both girls were blushing as Ang quickly changed the channel off of the porn.

"oh, so last night it was OK to have me help you but now you want privacy? So typical Ang...."

"Mark, I'm sorry, I didn't' mean it like that, you just... startled us. Hey we've got some pizza on, want to have some dinner with us?"

"ok, that would be cool. Hi Jules, how have you been?"

"I'm good, nice to see you again Mark"

"It's always good to see you too" Mark said a bit too quickly

"geeze do you two need a room? UGH, can we please eat?" And Ang popped up and headed for the kitchen. Mark and Julia looked at each other and smiled and both laughed a little at Ang's over reaction. Julia accidentally farted again with her laughter and immediately turned bright red....

"uhhh" she was at a loss for words, she was so embarrassed.

"it's cool, don't even worry about it, you should have seen my sis yesterday!"

"MARK! SHUT THE FUCK UP!" Ang yelled from the kitchen. Mark bit his lip showing he shouldn't have mentioned it and headed to the kitchen, Julia followed.

"here, let us help" Mark said as they all stood in the kitchen.

"grab some plates Mark, Jules can you get some drinks?"

"Sure what do you want? Diet Coke?"

"Ya sure"

"What about you Mark?"

"I have a better idea, I found out where Mom and Dad hide the keys to the liquor cabinet, who wants a real drink?"

"Really... so yesterday when you picked me up you were mad because you thought I was drinking, but tonight you want me to drink?.... that makes perfect sense bro"

"Well yesterday I thought you were hammered the way you were holding your stomach, I didn't know you just had to shit...."

"Mark, seriously, do you have to embarrass me in front of my friends all the time?"

"It's ok Ang, I already heard you left the party early, it sucks I couldn't go, my parents are so lame!"

"yea but he doesn't have to tell you all the details"

"OK OK, sorry sis, look do you want a drink or not?"

"yea I'll have a drink, can you pour me some wine?"

"me too" Julia chimes in.

The 3 of them sat down to eat dinner, it was awkward as no one was talking.

"so what were you girls just watching in there?"

"none of your business that's what Mark"

"Hey be nice to me or I'll tell Julia about last night!"

"Mark, you wouldn't!"

"oh but I would"

"We were watching lesbian porn, there are you happy Mark!"

"Lesbian porn? Are you two?..."

"no, geeze it's not like that, it's just what was on, we both like boys Mark"

"Well you can speak for yourself Ang haha, I like both!"

"Really? So do you think my sister is hot?"

"Mark, don't embarrass her!"

"I don't think I can embarrass her anymore than when she just farted in front of me..."

"it's true, it's OK Ang, yes I think you're sister is sexy. There"

"well this has gone sideways, why don't you go back upstairs now Mark. We're gonna go watch TV" and with that Ang stood up put her plate in the sink and went to the living room and laid down on the couch.

"well that didn't go very well, sorry I put you on the spot Jules"

"it's ok, shes just shy, I don't mind talking about sex" and she got up and headed to the living room leaving mark in the kitchen alone. He decided to head to his room and give them their privacy.

Jules stood at the entrance to the living room,

"so, do you wanna put hustler back on? I was kinda enjoying it"

"yea we can watch some more" This time instead of sitting on the chair she went and laid down on the couch with her friend cuddle up with her bum to Ang's crotch.

Ang flipped the TV back on and this time the scene was two girls, they were in a bathtub together but the tub was empty. One girl was sitting on the corner of the tub with her legs spread apart and the other girl was on her knees in the tub licking the other girls pussy. Julia immediately had her hand back down her pants this time under her undies. Ang could feel her friend rubbing her clit as her ass was moving and pushing on her own crotch/bladder. The girls couldn't believe what they saw next, the blonde girl that was on the corner of the tub started peeing all over the face of the petite brunette that was in the tub.

"holy shit! Is that really happening" Ang blurted out.

"wow... I had heard about this kinda stuff, but I've never seen it.

The blonde on the TV let out what seemed to be a never ending stream of piss onto the girls face. The girls were even more shocked when the brunette opened her mouth and started to drink the blonde girls piss. As the stream ended the girls switch places, the blonde girl started to eat out her friend and in another shocking twist the girls didn't see coming the blonde started licking the brunettes asshole.

"Wow people actually do that! I've seen lots of girls eat pussy but I've never seen a girl lick another girls bum hole! Have you Jules?"

"No... I wonder what that would taste like?"

"you do?"

"well, uh, I just mean, I know what girly juices taste like, but not a girls bum hole"

"You've gone down on another girl?"

"well, no, not exactly, but I have licked my own fingers"

"oh.." there was silence again and they focused their attention back on the tv. The brunette girl now started to let her flow of pee go onto the blonde who was drinking it much faster than the brunette girl was. As the scene continued the brunette slipped down into the tub that now had both of their pee in it, she bent over and took a mouthful of the mixture of both girls pee and spit it into the other girls mouth.

"uhhhhhh fuck!" Jules cried out, she didn't even realize it but she had been vigorously stroking her slit through the whole scene and she let loose a fantastic orgasm. As her friend came Ang immediately followed with her own orgasm she bucked her crotch forward into her friends ass pressing on her bladder. She couldn't control it, the excitement and build up, the alcohol from dinner and then the pressure of hitting her friends ass, the flow of pee started and couldn't' be stopped. She started emptying her bladder through her PJ's onto the leather couch; Jules immediately felt the warmth and rolled over seeing the puddle of urine expanding and soaking into her own pj's.

"Oh shit, I can't stop, fuck I'm so so sorry... uhhhhhh fuck it won't stop coming' Julia watched as her friend emptied her bladder, paralysed with the shock of it all she couldn't move, her whole lower body was now soaked in her friends pee. Right then Mark burst into the room

"is everything ok down here?"

"yes, yes everything is OK Mark, I think you should go, your sister just had a bit of an accident but we will get it all cleaned up"

"Oh no, did she shit her pants again?"

"What?..."

"No Mark! Fuck why did you say that" And Ang began to cry

"Babe what's wrong? Don't cry we'll clean up the pee, what did Mark mean again?"

"Last night, I left the party not because I was drunk but I really really had to poop and I didn't want to do it at the party, it would have stunk and everyone would have made fun of me, so I got Mark to drive me home and I shit myself in the car" Her crying subsided now

Mark was still standing at the door, he didn't know what to do, his sister and best friend were now sitting up on the couch covered in his sister's pee.

"it's ok babes, these things happen, we'll get you cleaned up, get a change of clothes it's all good. I'm sorry I wasn't there to help you last night too"

"To help me? You wouldn't have wanted to see me all covered in poo, this is all so embarrassing, two accidents in two nights"

"no no, don't be embarrassed that was one of the hottest orgasms I've ever had!"

"What?" Mark said

"oh... um, we were just watching, I mean"

Mark hadn't noticed the TV but he looked up and saw the two girls washing each other with what appeared pee in the bottom of the tub. Jules couldn't help but notice her friends brother had a huge boner pushing against his track shorts.

"Ang, do you want Mark to help you again? Or can I help, what would you like"

"I don't know" she looked like she would cry again

"here why doesn't Mark take you up to the bathroom and I'll get you us a change of clothes ok?"

"Ok that works".

Mark took his sister up to the bathroom

"hey it's ok sis, don't even worry about it we're here for you"

Angie pulled her wet PJ pants off and Mark reached out to take them

"no you don't want to touch these they are soaked in my pee"

"it's ok, no worse than yesterday" he said with a gentle smile

"I suppose" and she handed him her soiled clothing.

Mark stepped outside and waited for Jules to return, as she came towards the bathroom he said

"hey Jules, if you want to go in and then strip off your clothes you can just hand them to me I'll wait out here and won't look in"

"it's ok if you do......"

Mark didn't know what to say he just stood there and waited, a moment later her arm was sticking out holding her wet pants and undies. Mark could feel his cock grow in his pants as he held his sister and friends pee soaked clothes. He took them downstairs and tossed them in the washer. Meanwhile upstairs....

"Hey Ang.... I was thinking, I mean you already peed all over me and we need to shower anyways.... I kinda have to pee, I mean if you think you'd want to. ugh never mind."

"if I'd want to what? Kneel down in the tub like those girls while you peed on me?"

"no, I mean that's not...."

"it's not? That's kinda disappointing"

"really? I mean I could, if you wanted"

"I want you to pee on me Julia, will you?"

Julia intentionally left the door open just a crack. Angie got in the tub first and plugged the drain, Jules noticed and smiled softly. Angie knelt down in the tub and Julia stepped in, it was a corner tub without jets, but it had a nice little area in the corner almost like a bench. Julia sat on the bench and spread her legs, Angie moved in closer to her friend.

"are you sure about this?"

"yes, I was covered in my own poo yesterday, this can't be worse, but do it before I change my mind"

"Ok if you're ready"

Jules spread her pussy lips apart and a small stream gently trickled out and down between her bum cheeks. The girls giggled.

"This is harder than it looks, it's hard to pee in front of someone let alone ON my best friend"

Julia relaxed and immediately a stronger flow of urine burst from her young tight twat, the flow cascaded across her friends face and into her hair. The both moaned loudly as the flow continued to coat Angies young face and body. The golden arc continued and Angie surprised herself by opening her mouth. Without consciousness she was furiously fingering her twat, ramming her fingers in and out.

"Oh Ang, it's so fucking hot watching you drink my pee"

`ugggggggghhhhhhhh!!!!!!!!!!!!!' Angie groaned.

Mark was back upstairs now.

"Are you girls alright in there?" he said tapping on the door. As the door wasn't latched the door opened; Marks jaw just about hit the floor as he saw the sight of his sister being peed on by her friend. The girls looked at Mark as he stood there in wonder, his boner was evident through his sweatpants. Neither girl missed a beat as Julia continued the stream over Angies face.

"Are you going to join us Mark, or just stand there?" Jules said "we can see that you want to" nodding in the general direction of his crotch.

Mark peeled off his shirt and dropped his pants to the ground exposing his throbbing cock.

"come over here and I'll give you a BJ while I pee on your sister" Mark hopped stepped into the tub, standing over his sister with his legs apart. Julias stream was slowing as she leaned forward and took Marks cock into her mouth. She sucked the head of his knob and wrapped her tongue around it so that it was nice and slippery. With the stream of pee subsided Angie leaned in and began to lick her best friends glistening twat while her friend sucked on her brothers knob.

"Mark, will you pee on me, will you pee on me and your sister?"

"I would do anything for you girls"

"Anything Mark?" whispered Julia

"yes, ANYthing"

Mark stepped out of the tub and Julia slid into it, with both girls now on their knees looking up at him Mark could not believe he was about to pee on the two young girls, one being his sister. Mark managed to relax enough that a stream of pee started to flow. First he hit Julia right in the chin, wasting no time she opened her mouth and let him fill it with his warm golden liquid. Her mouth quickly filled with his warm pee and she gulped down as much as she could, the excess spilling out of her mouth down her chin and running down over her firm young breasts. Next Mark looked down at his begging sister.....

"are you sure Ang, I mean, once we go here... I mean we can't go back"

"I'm sure Mark, do it"

With that Mark let out his stream hitting his sister in the nose, she laughed as the pee splashed off of her. Mark continued to empty his bladder on his sister, he soaked her hair and face and finished his stream onto her breasts. Mark got back into the tub and they all shifted around so that Mark was standing with his back to the wall, Julia was now on her knees facing Mark and Ang laid on her back in the piss filled tub with her face between her friends legs. Julia softly took Marks throbbing cock into her mouth as Angie began to lick her twat. Angies hair was now completely soaked in urine from laying on her back and the aroma filled the room. Mark was too turned on by the thought of his sister eating out this other beautiful young teen.

"I can't hold out much longer Jules"

"Then let it go, I'm ready for you"

With that Mark exploded into her mouth, she gulped and sucked up as much of his spunk as she could. She shivered as Angie continued to work her tongue into her clit. With her mouth full of her friends brothers spunk she couldn't hold out any longer, she too began to shake as the orgasm ripped through her body. Her juices now squirting endlessly onto her friends face, Jules was in heaven. Angie lapped up as much of her friends' liquid as she could savoring the taste of her friends most intimate juices.

As her orgasm subsided she turned herself around and shifted with Ang so that she could collapsed in the tub with her head on her friends supple breasts. Mark sat on the corner of the tub his knees weak.

"Wow girls, that was, unexpected"

"oh Mark, you know you've wanted Jules forever"

"well, it wasn't just her that made this a night I'll never forget" this made Angie blush.

"Let's shower off and all go to bed, what do you think? Ang are we gonna bunk up together?"

"I have a better idea, my parents have a king size bed, what if we ALL slept there together?"

To Be Continued.
