Thanks to everyone again for your amazing support and responses! The tale continues...
I was awakened to a series of muffled girly giggles. "Wake up, Tommy," Leslee said, fixing me with a grin. "I've got a bladder full of piss, and you're going to drink up every drop of it, aren't you?" She was naked and kneeling beside me with her hands on her hips. Kathy and Marion were to my other side, underneath the covers still and giggling.
I somewhat blearily wiped my eyes and yawned. "Um, sure thing, Les," I said. I stretched my back and arms, kicked off the covers and laid back. "Come crawl up here and put your pussy on my mouth."
"You dirty fuck," she chuckled as she shuffled up and swung a leg over my head. "You like drinking my piss, don't you?" Her hairy red snatch was only inches from my mouth. Marion and Kathy maneuvered closer so they could see better, still giggling.
"Yeah, I love it, Les," I replied to her, opening my mouth in anticipation of her yellow stream. My cock was twitching and quickly coming to full erection.
"What do you love?" she asked me as she squatted over my face, her hands back on her hips. "Tell me!"
"I love drinking your piss, Les," I responded. My cock strained and throbbed as I said the words. My face was flushed with excitement and mild embarrassment. Marion and Kathy were only about a foot away to my left, I could hear them snickering and snorting as they watched.
"Say my full name," she snapped, "And use the word 'pee pee'. Now tell me again!"
I hesitated for a second. "...I love drinking your pee pee, Leslee," I said. Kathy and Marion both squealed in delight and mirth next to me. My face was burning a deep red now with embarrassment. My pulse was pounding in my cock as it surged to rigid hardness.
"I want to hear that one more time," Leslee teased me in a sing-song voice.
"I love drinking your pee pee, Leslee!" I affirmed louder this time. Kathy and Marion snickered and tried to suppress peals of laughter. I was incredibly turned on by this treatment. I felt ashamed and humiliated, but I was loving it! I couldn't wait for her to start evacuating her bladder so I could taste her piss. My mouth was watering, I was dying for it!
"Ok, I want to hear one more thing before I let it go," said Leslee. "I want to hear you ask me to piss into your mouth so you can drink it. Use the word 'pee' again, I like that. And you'd better be polite!"
"Please, Leslee," I begged her, "Please pee into my mouth so I can drink it!"
"Good boy!" she praised me. Threading her fingers into my hair, she lifted my head up and raised my mouth to her pussy. My two other sisters were giggling away like mad. I engulfed Leslee's labia and prepared to receive her golden offering. Her lips tasted of salt and the flavour instantly sent shivers through my body. "Ok, I want you to concentrate really hard here, I don't want you to spill a drop on my bed," she said as I locked my mouth onto her lower lips. My cock was twitching uncontrollably. "And one last thing," she said. "Smile, you're on kinky camera!"
With that, she unleashed a torrent of urine into my mouth. I frantically rolled my eyes over to my other sisters, and indeed, Kathy held a camera pointed directly at me! I panicked!! I tried to move, but Leslee had me by the hair with her snatch pushed into my mouth. Her urine tasted awful!! Unbelievably sour, overwhelmingly strong! I choked and gagged, my face grimacing in disgust and horror. I struggled as Kathy and Marion screamed in laughter. Leslee's stinking piss roared into my mouth. With superhuman effort I managed to choke down a mouthful. It was salty and acidic, bitter and foul. It kept coming like a geyser, squirting into my mouth and filling it. I resolved myself to overcome the terrible flavour and just swallow down every drop as quickly as I could. I opened my throat and chugged another mouthful down. Leslee's flow was constant and instantly my mouth was again full. I chugged and chugged, the vile liquid being guzzled directly from her bladder, through her pee-hole, into my gaping mouth and straight down my throat into my stomach.
As I began gulping down her piss, she relaxed her hold on my hair slightly. "Good boy," she crooned to me. "Good thirsty boy, drink up all my hot stinking piss. I've got a new name for you. I'm going to call you Piss Pot from now on," she mused.
I moaned in between gulps as my body went wild with chills. Once again this horrible, rancid, most disgusting taste I'd ever beheld became ambrosia. The nectar of the gods. The vile, volatile orange brew she was voiding into my mouth was transformed into a potion of ecstasy, the source of my life and my reason for being. I gulped down her pee with enthusiasm and force, sucking the piss right out of her cunt. It was paradise! The more sour and putrid her piss, the more joy it brought to me! God, I was going to come again!!!
I desperately sucked on her vulva with all my might as waves of rapture surged through my body. My hips thrust forward involuntarily as my entire abdomen was seized in a warm, crushing grip that squeezed the breath from me. I fairly screamed into Leslee's cunt as I ejaculated, desperately locking my lips onto her twat to form a seal so I wouldn't miss a single drop of her stream. Thankfully, it had slowed slightly by now.
"Shit, Tom's coming in his pants again!" gushed Marion. "Get that on film!!"
Spurt after spurt of thick, sticky semen blasted into my pyjama bottoms as I moaned with the intensity of my release. Leslee's flow of urine had slowed to a trickle. I still had my mouth in a death-grip around her vulva, sucking the last glorious drops of urine out of her with zest. "Fuck, you are a dirty fucking piss pot, aren't you?" growled Leslee. "Coming in your pants just from drinking down all my hot piss? Yeah, you dirty fucking dog. Get the last drops. Taste it. Savour it. Now lick my cunt. Make me come. Yeah, do it. Lick my cunt."
I didn't need any encouragement there. I continued sucking on her pussy for all I was worth, lapping and slurping up every drop of her piss, tasting every inch of her vagina, sliding my tongue all over the folds of her snatch and flicking over the hardness of her clit. It didn't take long before she grabbed my hair in both hands and began bucking on my face. "UUHHHNNNN!!" she groaned as she began to orgasm. She doubled over and ground her pussy onto my face as she thrust and twitched, cumming with intensity as her well-muscled torso convulsed in joy. "GOD, YEAH, SUCK MY CUNNNNNT!!!" she howled as came, gasping and gyrating with her eyes shut tight. Slowly she relaxed and collapsed forward, panting and moaning. "Oh my god," she breathed. "Oh, fuck. I've never come like that in my life. Oh my fucking god."
