Brittney places her hand on your cheeks and pushes them into the side of your mouth.
What the hell?, you think to yourself. Your mouth is forced open and suddenly you can smell the distinct smell of urine. You try to close your mouth but it's no good, you just end up biting your cheek. You look her in the eyes, pleading her not to do this. She just blows back a kiss and then the piss starts to flow.
The taste isn't as bad as you thought it would be, and not nearly as bad as the smell. After a few seconds you have a good mouth full. Brittney tightens her mussels and cuts off the supply. "Swallow" She says simply. You do as she commands and she fills you up with another mouth full. After a couple of mouthfuls, she takes her hand away from your mouth. It's too late to resist, you continue to drink Brittney's piss.It actually tastes pretty nice you think. You start to wonder what her pussy tastes like.
The other girls watch speechless as you drink all of Brittney's waste. You can't believe how much there is. She fills you up, time and time again. All you can taste is her piss.
"You're a good slave Tom!" Brittney says. "You're so good, I'm going to let you lick my pussy when I've finished pissing". "Hell, If you drink your sister's piss, I might even give you a blow job!". She says locking eyes witht Tiffany.
"No way" Tiffany says, almost angry at the thought of it.
"Think about it, babe" Brittney replies, no longer pausing her piss and, instead, just letting it all out into your mough. "All the times he picks on you, all the times he tells you what to do, how to act! Things will be different after he drinks your piss in front of your friends! We'll remind him every time he says or does something bad to any of us. He'll always be our little piss slave!".
"OK" Tiffany resigns, "I'm not sure I can go though".
"At least try" Brittney responds.
Brittney, who has finished pissing now, lowers herself further down. You lap your tongue up and down her pussy, savouring the taste. She doesn't let you enjoy it for long; she stands up and moves aside. Before you know it, you're staring up at you're sister's hairy pussy. The smell is overpowering. You close your mouth and eyes tight, wishing the hairy monster away. How is a girl so young, so hairy? You've done some fucked up things today, you figure, but you're not going to let your sister piss in your mouth.
Then you feel Brittney, once again, touch your cock. Her hand holds your balls and then you feel a warm wet feeling engulf the head of your cock. Brittney is giving you a blow job! If feels like nothing you've ever felt before! You enjoy it for a few moments, then you remember what she said. You open your mouth for your sisters piss. It's going to happen, you figure. You've gone well past the point of no-return. You may as well enjoy the blow job.
It seems to take ages and you wonder if you'll ever get the smell of your sister's snatch out of your nose. Hopefully, you think, she won't be able to go. Then there is a little squirt of piss. The taste is horrible, nothing as nice as Brittney's piss that you had guzzled down earlier. The squirt is followed by another one, and then another.
The flood gates open as your sister unloads piss into your mouth. You fail to notice that Brittney has stopped sucking your cock or even that she has taken out her phone and is recording you drinking your own sisters piss. The other girls are in hysterics. Crystal starts taking off her pants, "I'm next!" she says.
"No, I'm next!" shouts Wendy in a childish tone. Ripping off all of her clothes.
"It's ok girls", Brittney says as she watches her phone capture you drinking your sister's waste. "You'll both get plenty of turns tonight and for a long time to come!".
"Anyway" your sister says "first I ....."
