The new gym urinal 3
I whimpered, on my knees and handcuffed behind my back, as I looked up at David laughing sadistically and back down at my dog bowl filled with the piss-soaked food.
"I'd hurry up and eat it if I were you, or I'll be forcing your face in the bowl with my foot".
I felt the back of his foot behind my head.
"Or even worse, I'll stomp it into mush, and make you eat your food from my foot".
I groaned as I lowered my face into the bowl and started to eat my disgusting meal.
"Fuuuck" I heard David behind me moan and jerk his cock off. He was clearly getting off from degrading me like this.
The food mixed with the piss tasted gross, and the texture was worse. It wasn't as bad as I thought it would be, but maybe because I was getting used to the taste of piss from serving as a urinal pipe.
When my bowl had about half its contents left, David moved in front of me.
"You know what, it's great that you're so eager to please me, but I think you deserve more humiliation"
He lowered his bare foot into the dog bowl and started to break the rest of the food down. He then pulled a nearby chair towards him sat down, and ordered me to clean his feet. I was made to lap the rest of the food like this - making sure that his foot remained clean, even between the toes.
After that humiliating ordeal, David made sure I licked the inside of the bowl clean. I felt like a subhuman animal, a beast forced to eat disgusting gruel that had been trampled by his owner.
"I think you've earned a small break, bro. How about you serve as my footrest, and lick my balls for a bit? You better worship me and make me feel really good. If I get bored, I'll just hook you up to the urinal for the afternoon. I won't see you until our workout together tonight."
He extended his feet over my back. I was still handcuffed, so I had to balance with my feet and knees to not fall sideways. David pulled out his balls from his shorts. "Dig in".
I desperately lapped, sucked and fondled his balls with my mouth as he slowly jerked off. "Fuuuuck bro. Feels so good having my best friend drink my piss and service me. You're making me rock hard, bro."
And surely enough, his cock inflated to a full 8 inches. David kept jerking off, occasionally slapping my face with it as I kept worshipping him.
"I own you, bro. I've already got you hooked to my piss, I'll eventually turn you to a cum dump. Your dick isn't even yours now. I love the idea that I turned your dick into a caged nub."
He shoved his cock down my mouth, making me choke.
"Fuuuck sorry bro, couldn't resist. Was thinking of throat training you some other day, think of this as a preview".
He slid his cock up and down, making me wretch and choke each time.
He then abruptly slammed his hips into my face, impaling my throat with his entire length. He told me to hold his cock in. Tears ran down my reddening face as I uselessly gasped for air.

I let out a muffled wail as David took a picture with his phone.
"Fuuuck, that's it bro. Look at the camera... perfect. I'm going to jack off to those pictures of you, when I'm not using you like this."
I took in a second to realise how pathetic I looked. Collared and handcuffed, fed copious amounts of piss, and now suffocating on my best friend's cock. I made gagging noises as I slowly adjusted to his length down my throat.
"Bro, you have no idea how much water I drank in preparation for this. I figured that you would also like to drink my piss directly from my dick, and not through piping. Good slave boys like you drink piss wherever, whenever."
He started to piss down my throat in spite of my panicked, protesting wails. I couldn't even taste his urine as his cock was too far down my throat. I could only stare pleadingly at him and make pathetic gulping sounds as he recorded my abuse with his phone. I could feel my stomach slosh through all the liquid I drank.
David then slowly removed his cock from my mouth, allowing me to take a breath.
"Give it a kiss."
I grunted in defeat as I kissed the tip of his cock clean, too exhausted and humiliated to form words.
"I want to cum in you so bad, but I'll keep that for later today."
My captor let me rest for a little bit afterwards. He uncuffed me, letting me stretch my arms. I however remained collared and leashed, meaning I had to stay close to him. I was allowed to sit down and lean against a wall - David stayed on the nearby chair and played on his phone, occasionally playing with my nipples or stroking my hair.
I woke up suddenly - I figured I must have fell asleep during the break. I panicked as David had chained me back to my position during my sleep. I was on my knees facing the screen on the wall, with my arms and hands shackled, mouth pried open with the ring gag. The urethral sound was already fitted through my chastity cage.
"Wakey wakey, hope you were able to rest a bit before your afternoon shift."
I let out my usual pathetic grunts and tried resisting a bit - which was totally useless, but it made my permanently locked dick leak more. I felt my precum trickle through the sound and into the pipe.
"I figured you'd like some additions to make your service more enjoyable, bro. Enjoyable for me, obviously."
The first addition were a pair of clamps cruelly fastened onto my nipples. I cried out loud in pain as I felt the weight of them against my chest. The chain was fastened to another hook right in front of me - which forced me to keep an upright position.
"There you go. You were wriggling a bit too much last time and this ought to make you keep the same posture."
He gently tugged at the chain, which made me scream in pain.
"This better stay on, bro. If you pull it off, I'll be piercing your nipples with large rings and using that to chain you instead. Think about how hard those piercings would be to hide in public."
I wailed in agony as my sensitive nipples were tortured. The idea of nipple rings was fucked up and I seriously hoped that David couldn't see how aroused I was getting by his abuse, again.
The second addition was made to the mask I was forced to wear.
"I've been wearing the same underwear for a week now. Worked out everyday in them, even pissed and cummed a few times in it just for you, bro."
His crusty boxers were pressed against my face before he fastened the mask back onto me. I was forced to take each breath through them, filling my nostrils and my lungs with the potent smell of his sweat, piss and cum. Disgusting, but hot.
"I can tell you're turned on by this, by the way", he grinned. Fuck, fuck, fuck. "I'll think of other things to mess with you, bro. See ya later."
He gave my ass a few playful slaps before leaving me. Just as I heard him lock the door, my mouth was immediately flooded by the piss of an athlete using the urinals upstairs. I was back on my routine - and I started gulping the urine again, just as recycled piss flowed out of my cage. Just a pathetic piss tank.
