Part 4: Rex fucks me -------------------- Leo nudged me awake the next morning, pushing my head down towards his groin "I need to pee" he told me as I slid down the bed and took his cock in my mouth ready to start my first full day being his urinal. After a few moments my mouth started to fill with his piss, strong and rank first thing in the morning but I was used to it now, so taking his cock in my hand & squeezing him slightly to ease the flow swallowing his piss down as he filled my mouth mouth again and again while I absently stroked my hardening cock until his bladder was drained. We got up, got dressed, had a bit of breakfast then Leo suggested we take Rex out for a walk in the nearby park. It was a warm sunny day so we heading out just wearing shorts & t-shirt with Rex on his lead bounding between us eagerly. Despite the weather the park was quite quiet, most people still stuck in work and unable to take advantage of the weather, so when Rex veered off the path into the undergrowth sniffing for a place to pee I couldn't resist and followed him. As Rex cocked his hind leg up against a tree I knelt down beside him to get a good look, placing my arm around his flank and rubbing his side as Rex started piss, his stream hitting the tree. My other hand started to rub his stomach and I was mesmerised watching Rex's piss streaming out of his sheath. I dangled my fingers into his piss stream, it was warm & I could smell the distinct odour of Rex's dog piss hitting my nose. I put my whole hand into the stream then brought it up to my face, getting a good strong whiff before placing my fingers in my mouth and licking my hand clean, an instant reminder of what Rex's piss tasted like and how different it was to Leo's came flooding back to me as my cock grew hard in my shorts. I took another sneaky taste of dog piss and then when Rex finished peeing I stood up but Leo pushed me further into the undergrowth "I've got to piss now if I'm not too hard after that little demonstration" he said "get back on your knees". I did as instructed, glancing around Leo's side to make sure there was no one on the path, as he pulled his semi-hard cock out of his shorts & pointed it at my face. I stared at his piss slit as it flared slightly then his piss hit me straight in the face. I opened my mouth quickly to swallow it before he soaked my t-shirt, gulping down a mouthful of Leo's piss before putting the tip of his cock into my mouth to drink as much of his piss as I could. I managed to swallow a lot of Leo's piss but still managed to soak the front of my top. After Leo had emptied his second bladder load of the day down my throat I stood up, pulling my top up to suck some of his piss off my t-shirt, now dark all down the front from the wet piss. The rest I let dry naturally as we continued our walk, not caring if anyone saw my top was wet, i doubt they could guess the source anyway and the smell of Leo's piss stayed with me the whole time. When we got back to Leo's place he filled Rex's bowl with water "Let's get him topped up for later, and I think I will do the same" Leo said, grabbing a couple of cans of soda out of the fridge. Later on Leo suggested we give Rex a bath to freshen him up, so we took Rex outside to the back garden where Leo had a hose attached and gave Rex a good wetting down with warm water. Leo handed me a sponge, taking one himself, and adding some dog shampoo to them we lathered Rex up all over. Rex was definitely enjoyed his wash and having completely soaped up his underbelly I massaged lather along his balls and sheath with my bare hands, paying special attention to the tip of his sheath, giving them a thorough massage and clean, then stepped back before Rex could get too amorous. When we finished Leo gave Rex a thorough hose down and we dried him down with a couple of towels. As evening fell, we were sat in the kitchen drinking lager when Rex started to get fidgety, moving towards the back door and sniffing before turning to us expectantly. "I think Rex is gonna want to pee soon" Leo said "And I'm probably not far behind. Let's finish these drinks then head upstairs to the bathroom if you're ready." I was more than ready, gulping down the last of my can in 2 swigs and smiling at Leo as I got up and grabbed his hand. We rushed upstairs, Leo calling out to Rex to follow. I was still wearing the t-shirt with Leo's dried piss, a large yellow stain on the front, so once in the bathroom I kicked off my trainers and shrugged off my shorts, my dick already hard in anticipation, but left my t-shirt on. Leo stripped off to just his socks, his dick, semi-hard, swinging heavily between his legs. Rex trotted in the bathroom and you could see he already knew what to expect as his cock was starting to poke out of his sheath, a good inch of pink & wet doggy cock showing through. Spotting the towel still against the wall from yesterday he started to bounce over but luckily Leo grabbed him by the collar as he went past, halting his progress. "I hope you're thirsty Chris, Rex looks like he's about to burst". With another glance between Rex's hind legs I grinned and went over to the wall, arranging the towel into a pillow and laying my head down on it, wiggling to get comfortable and arranging my t-shirt neatly ready to soak up any spills. Rex was anxious to get to me, straining against his collar, reaching up on his hind legs as he tried to get free and I looked over between his legs at his protruding cock swinging between his legs, hungrily. Leo relaxed his grip on Rex's collar and he broke free, bounding over to where I lay. Rex gave my face a quick sniff then moved his snout down my torso to my groin, giving my throbbing cock a quick lick, then with his hind quarters right in front of my face he cocked his one leg and I stared up at his pink cock jutting out of the sheath, a drop of liquid already forming at the tip. Knowing what to expect I opened my mouth wide just as Rex started to piss, his doggy piss stream hitting me square in the face requiring me to make only the slightest adjustment for it to go straight in my mouth. I let my mouth fill up with Rex's dog piss till I could feel it running out of my mouth and down the side of my face, getting a good strong smell of his doggy pee before i closed my mouth and swallowed, savouring the more bitter and sour taste dogs piss had. Glancing between Rex's fore and hind legs I looked straight into Leo's eyes as he knelt down the other side of Rex, moving in for a good close view of me drinking his dogs salty piss. Greedily I opened my mouth again and let it fill up with dog piss before gulping it down as Rex's piss ran down my neck. Getting another mouthful I brought my hands up to my face, swallowing Rex's piss as I rubbed the continuing stream into my face and through my hair, rubbing down my neck until my head was completely soaked in dog piss. Moving one arm under Rex's belly, I grabbed around his back to pull myself up so my mouth was at the tip of his cock, now about 2 inches protruding from his sheath. My open mouth filled with more of Rex's piss and as I swallowed, the excess pouring all down the front of my t-shirt. Pulling myself up a little more, I took the tip of his dog's cock in my mouth, swallowing as fast as I could as Rex pissed straight into my mouth allowing me to gulp down another few mouthful's. Opening my mouth and moving my head back just a touch i rested Rex's dangling cock on my tongue and let dog piss flow into my mouth until it was gushing out either side of my mouth again, giving Leo a good view of my mouth full of Rex's yellow piss, then closed my mouth around the tip and swallowed fast. Rex's stream was finally starting to ebb so I lay my head back on the towel, letting the stream dribble into my mouth, drinking the last drops until it came to a stop. As it stopped I leant up, taking Rex's cock in my mouth and started to suck up and down on what of his cock was poking out of the sheath. Straight away I could feel my mouth getting fuller, requiring me to pull back a little more with each stroke as Rex's cock eased out of his sheath growing rapidly whilst I sucked on his cock until about 8" of thick dog cock was sticking out and I glided my mouth up and down on it, wet with my saliva and dog pre-cum. I reached up and took hold of the base of Rex's cock, near the balls and could feel his knot starting to form in my fist. As I looked up at the tip of his cock, it was jerking slightly and a little bit of pre-cum was oozing out in time to each throb. I took Rex's cock inside my mouth again, sucking up the pre-cum as I did. Now with Rex's cock fully extended and his knot starting to form Rex started driving his cock into my mouth, much rougher than last time & I was gagging with each thrust but unable to manoeuvre to avoid choking so was frantically attempting to push Rex off me a bit. Leo noticed my predicament and pulled Rex back slightly, hugging the dog to his lap. "It seems Rex is really horny tonight, I think the last couple of days, and all the attention he has been getting has got him going, we could let him calm down for 5 minutes rather than have him choke you, or maybe you should just let him fuck you like he obviously wants to and let him get it out of his system!" Leo said half jokingly. I looked up at Leo, then sat up. "What about his claws? I don't want to be scratched to death. "I have hard floors throughout so have to keep his claws short to avoid scratches." Leo explained. "You will be fine I promise." Looking at Leo kneeling with Rex pulled into his lap, holding the dog affectionately I made my decision then got onto my knees, offering my ass up towards Rex. Rex needed no instruction and jumped on my back, his fore legs hanging just over my shoulder and I could feel his cock prodding around near my ass, the tip leaking pre-cum over my ass cheeks and ring, lubricated it, as Rex tried to find the spot to enter me. Leo spat into his hand, and pushing Rex's cock out of the way slightly he rubbed his spit over my asshole, inserting a finger to lubricate me inside, then he grabbed Rex's cock and pointed it straight at my hole. I could feel wetness building around the opening as pre-cum kept dribbling out of the tip of Rex's cock then Leo aimed it straight at the entrance and I felt Rex's cock start to enter my ass as Leo moved his hand away. Rex's cock was big, not as big as Leo's but I felt it slide into my ass a good 6" until his knot hit the entrance to my hole as I gasped. Rex's hips seemed to be on auto pilot as he started to thrust back and forth into my ass at a hundred knots as he panted by my left ear, each time his knot hit my ass it would open me up a little bit more and more of his dog cock slid inside me. Leo knelt by my head, waving his cock at my mouth "I hope your still thirsty Chris because I haven't had a pee since lunchtime". I nodded at him, taking the head of his hard cock into my mouth, wrapping my lips around it. Leo started to piss straight into my mouth and I swallowed hungrily, as I pushed my ass back and upwards to meet Rex's frantic thrusting until all of a sudden I felt Rex's knot slide right past my sphincter and my ass closed around his knot. My ass was finally full of dog cock and now Rex's dick was fully inside me, his knot seeming to swell even bigger, filling my ass more than I thought possible. Rex was thrusting frantically and it was like being fisted as his knot pulled against my entrance from the inside, stretching me wide open as my ass massaged the knot that couldn't quite escape, before he thrust back in. I was still greedily swallowing Leo's piss and he pulled his cock out of my mouth, sending the stream over the back of my head, soaking my hair before aiming straight at my face. I opened my mouth letting it fill with Leo's piss, looking up into his eyes as I closed my mouth around his cock head again and swallowing more of his piss down my throat. Rex's hips were banging against my ass at a much faster pace than when Leo had fisted me and the entrance to my ass was aching from the assault I was getting. Then Rex's panting seemed to slow slightly but increased in intensity in my ear as he tried to drive as much of his dog cock inside my ass as he could, his thrusts getting longer in and out each way, then suddenly I felt Rex shuddering, his thrusts so fast they seemed to blend into one massive shake as his cock drove further inside me and I could feel my insides expanding as his cock swelled and Rex started to pump his dog jizz into my guts as I drained the last of Leo's piss down my throat and into my stomach, sucking desperately at the drips that indicated he was almost dry. Rex's thrusts slowed almost to a stop as he emptied the contents of his doggy balls deep, then his panting came to a stop. As I sucked on Leo's cock, Rex licked my ear but was still lying on top of me, breathing slow and heavy and I could feel him trying to get off me but his knot was still locked inside the entrance to my ass. I wondered if we would be stuck here for a while but the fisting Leo had given me yesterday had made sure my ass could stretch wide open and slowly but surely I could feel the knot easing past my ring as it decreased slighty in size & my ass stretched open, until, with a plop, his cock slid out of my ass. Rex scrambled off my back and stood beside me and I glanced at his cock, coated with sticky dog cum. I leaned over, hugging his back as I pulling his hind quarters toward my mouth and, wrapping my lips around his cock, took it into my mouth, cleaning it of all the dog cum clinging to it and sucking his cock into my mouth, as I felt his cock slowly start to slid back inside his sheath as I did. I savoured what little I could of his dog cum since most was still inside my ass, but Leo, reading my mind, slid 2 fingers in my upturned ass before withdrawing them and offering them to my face. His fingers were coated with dog cum and I sucked them clean, relishing the taste of Rex's cum in my mouth. Rex, now spent, padded off to the corner of the room and lay down as Leo came up behind me, kneeling in front of my ass and poked around my hole with his cock before sliding it up my ass brutally, right to the hilt, until his groin and balls slapped against my ass cheeks, the dog cum acting as lube, he then withdrew and moved round so his cock as pointing at my face. I took his cock in my mouth and cleaned all the dog cum off it before he moved back round to my ass, sliding his cock inside me before once more pulling out to let me lick him clean again. Leo did this a few times so I could suck as much dog cum off his cock as possible then started to finger my ass in earnest. Already wide open from when Rex tore his knot out of my ass earlier, it didn't take Leo long before, having slide 1, 2 then 3 fingers inside me in quick succession, had pushed all 4 fingers up until his hand caught at the thumb, then he rotated his hand from side to side, opening my ring more as I groaned appreciatively. Leo withdrew his hand slightly then, making his hand smaller, started to ease his whole hand into my ass, stopping just before the widest part of his fist. I moved my head down towards the floor putting my elbows on the ground and stuck my ass straight up to meet Leo's hand, my t-shirt sliding down my back towards my shoulders. I grabbed the front of my sopping wet t-shirt, stained yellow from 3 loads of piss, and pushed it into my face to savour the smell of Leo's piss mixed with Rex's, dog & boy's piss together then rammed a wad of the cloth into my mouth to suck out the liquid as Leo gave a final push and his hand slipped right into my ass, my ring closing around his wrist possessively. Leo eased his hand further in, my ass channel well lubed with dog cum easing the way as I groaned through my t-shirt and pushed my ass back as far as I could to meet his arm. I could feel him sliding further inside me bit by bit until his forearm was about half way inside my ass, then Leo clenched his fist and started to pull his arm back out until his fist met with my sphincter and came to a stop, his fist still clenched Leo started to push his arm back up my ass until it could go no further, but still I pushed against his arm, trying to get just that little bit more of his arm inside me and Leo held firm, both of us straining against each other, the feeling of fullness overwhelming until he almost reached his elbow. Then Leo slowly started to ease his arm back out until he reached my ring, but didn't stop, slowly pulling his clenched fist past my hole, almost dragging me back into him until his hand came out of my ass as I gave a deep low groan. Leo slid his hand in and out of my ass a few times as I reached with one hand to grasp my cock, squeezing hard, whilst the other hand rubbed my piss stained t-shirt against my face and open mouth. Pulling his hand out of my ass again Leo reached over, lying across my back, and brought his hand towards my face, it was slick with dog cum & my ass juice and I opened my mouth as he stuck one of his fingers in for me to suck clean, at the same time his other hand was poking around my ass as he eased that one past my ring and started to push it into my ass. As Leo filled my ass with his other hand I greedily licked and sucked at his fingers of the first, sticking my tongue between them to slurp at the mess on them, tangy ass juice and bitter dog cum mixed together to form a glorious cocktail. Leo stuck all four fingers in my mouth as he pulled my head back while pushing his other hand forward as I squeezed my cock violently, rubbing his hand all over my mouth until I had sucked off all the mess, he leant back, and with his one hand still inside my ass started to push his cock into me as well, until his balls were against his wrist. With his hand resting against the inside of my ass ring Leo started to pump his cock into my ass, his cock head sliding past his palm as he fucked me and wanked himself inside me, harder and harder until I heard him groan and fall onto my back breathing heavily, his cock jerking inside me against his hand as he spilled his cum into my gut. Spent, Leo pulled his cock out of my ass and with his hand still inside me, flipped me over onto my back. Shuffling round he dangled his cock over my face and I reached up on my elbow to take his oily slick cock in my mouth, sucking it clean of cum, then Leo slowly pulled his hand out of my ass and my ring closed behind it, suddenly empty as he stuck a finger in my mouth. I was squeezing my cock hard and slowly moving my hand up and down the length while i cleaned Leo's other hand of Leo's cum, still able to detect the scent and taste of Rex's dog cum mixed in with it all as I sucked each finger, wrapping my lips around them tightly as he pulled each one out of my mouth. Leo took his original hand in a fist and started to push it against my ass as I slurped and sucked on the other one, picking up pace as I frantically jerked my cock. As Leo's fist stretched my ring to it's maximum and his hand started to slide in again I started to cum, great big spurts shooting over my stomach & chest as my ring sucked Leo's hand back inside me. Having emptied my balls, I lay there panting for a little while, Leo's one hand still in my ass, idly sucking the fingers of his other before Leo removed it from my mouth and pressed down on my stomach to steady me as he eased his fist out of my hole. He took that hand back up to my mouth so I could give it a good clean as I looked into his eyes adoringly, a lazy smile on my lips, then scooping up the cum from my stomach, he licked it off his hand before moving down to give me a deep kiss, my cum now mingling in my mouth with the taste of Leo's cum, Leo's piss and Rex's piss & cum. My mouth must have been foul but Leo didn't seem to care as he tongued me deeply, falling on top of me so we were both lying on the floor, hugging tightly and kissing until me both ran out of breath. Exhausted, we both showered and washed each other down, then we hit the sack and I was fast asleep before I knew it. My time as Leo's personal urinal was coming to an end at least for now, but when we woke up the next morning with Leo's piss hard on sticking in my back as he hugged me to him, I swivelled round and kissed him deeply despite our morning breath and asked him huskily if he had any parting gift for me before I had to head off. Sitting up Leo swung out of bed, pulling me up and practically frog marched me into the bathroom where I dutifully got down on my knees so Leo could slowly feed me his rank morning piss as I tugged furiously at my dick til I shot my wad over his calf. Then taking his cock in my mouth I drained the last of his piss before sucking his cock until he came all over my face. Still rubbing my own cock lazily I sucked his cock clean then started to scoop his load off my face and into my mouth until I had eaten every last drop of his cum. I gave my face a quick wash and tidied my hair but declined a shower or to brush my teeth cause I wanted Leo's scent on my body and the taste of his piss & cum in my mouth for a little while longer. Then grabbing my stuff he gave me one last long lingering kiss before I headed off, Leo promising to call me next week when he was free. With a bounce in my step I headed off to the train station, happy knowing I was Leo's personal urinal, happy to be his personal urinal for as long as he wanted me and looking forward to getting home and having a good wank with something big up my ass while I could still taste all his piss & cum in my mouth.
