The new gym urinal 5
The five minute break felt really short. I had to take a minute just to stop shaking. Another minute was spent begging David to lower the weights. My pleas were met with a slap in the face and a punch in the gut - his cruel way of saying no. I considered running - which would have been stupid, given my pathetic appearance - but as if he read my mind, David pulled out a pair of ankle cuffs and fastened them on my legs. A short chain connected them together. Now, I could only take very short steps.
"I found it fucking hot when you crawled on the floor like a worm. Now you can concentrate on doing only that from now on."
David was stroking his hard-on through his shorts, clearly enjoying this.
After my break, he made me do two more sets, with ten reps each. I failed both tasks, at 7 and 5 reps. I got whipped 7 times as punishment. My chest was on fire from the workout, and my back was as well from the lashes.
"I bet you need a piss after serving as an urinal today". He was right - I could really use a bathroom break. I nodded, hoping he would take me to the urinals. Instead, he pulled out a protein shaker from his bag.
"Piss right here bro." He held the cup in front of my locked dick. I obliged - the chastity cage prevented me from urinating quickly, forcing me to control my bladder flow. The cup slowly filled with my own piss. I felt relieved once I was done - the cup was about half full.
I grunted when I saw David take out protein powder from his bag, and dunked a scoop into the cup. After screwing the lid shut, he started to shake.
"Unflavoured. Wouldn't want to hide the taste, would we?"
Once he was done, he held the mixture in front of my face. Knowing I would be in for a whole world of pain if I refused, I obediently opened my mouth and started gulping my own recycled piss mixed with protein. The taste was even worse than plain piss - much stronger. The texture of protein powder didn't help.
"That's right bro, gotta make sure you get your daily intake. Water is going to be a luxury for you around me - any hydration you get should be filtered through other men." He said this while groping my pecs, making sure to tweak my clamped nipples.
Once I was done, David took the shaker away from me. He surprised me by taking a swig of the mixture himself. Maybe he was a bit of a piss pig himself. "Gross", he laughed.
David continued tormenting me with the workout routine he designed. My chest and my shoulders were on fire after the series of exercises. Each failed rep added a red welt onto my back and ass. If my form wasn't deemed perfect, David would force me to do that rep again, effectively meaning more lashes as I inevitably failed due to exhaustion. The fact that the weights were heavier didn't help.
The final exercise David wanted me to do were chest dips.
"Hang on, don't start yet. Let me get a dumbbell so that you can do weighted dips."
My captor returned with a 10-pound dumbbell. I got worried as he had an even worse cruel smirk on his face than usual.
My fears got confirmed as he ordered me to squat. The dumbbell was tied to my balls with a length of rope. I was then made to stand up. I was in agony as my balls were forced down low. David laughed, and gave my nuts a few playful taps.
"Come on bro, better start now, or I'll whip you in the balls."
I let out a scream of fear and pain, and I started doing the dips. David made sure I did them slowly, with good form. Each rep was harder than the previous one, as the pain increased exponentially. Looking down, I could see my balls pulled down from my caged package. I gritted my teeth as the humiliation of being abused for my friend's entertainment took over me.
After counting out ten reps, I collapsed on the floor, in agony because of my balls. I felt David stroke and fondle my balls as I laid heaving. A light squeeze made me yelp in pain. "Come on, up. Ten more." I shakily got up, too afraid of punishment despite the pain. I was so vulnerable that I had no choice but to obey.
My best friend was not done with me after my dip exercises. He ordered me to hold in a squatting position, legs spread apart, hands behind my head and looking straight forward. He shackled my hands to my metal collar. The weight around my balls made it impossible to stand up.
"Hold that position. If you don't, you'll be whipped again."
David then crouched behind me and started rubbing my caged crotch with his hand.
"I see you're still enjoying yourself. It's a shame all that precum is going to waste."
He put his hand in my jockstrap and collected a large amount of precum. I shuddered when I felt his raging hard-on press against my tight butt as he did so.
"I sadly forgot my lube at home. Thankfully, looks like my piss bucket and soon to be cum dumpster comes with its own lube dispenser."
I wailed in defeat as David slicked his cock with my precum. He spat onto my hole and slowly pushed his rod inside me. I screamed on the top of my lungs. I was in pain from the forced squat position I had to hold and from the sudden intrusion. The utter humiliation of being penetrated with the help of my own precum. Yet every part of me loved it. Feeling utterly owned and violated by my best friend in an empty gym.
David slowly made it to the hilt - I could feel his hips against my ass. I gasped as I tried adjusting to the girth of my best friend and owner's cock. He hadn't prepared me for this at all, meaning that I was extremely tight.
I was then brutally fucked in that position. He slammed his hips up and down into me, making sure I feel his entire length. The room was filled with sounds of sex - my animalistic shouts and groans along the occasional "FUCK" when he used extra force to push into me, as well as the obscenities David was yelling at me. The utter degradation of being called his bitch, his hole, his cocksleeve, his urinal, his fleshlight, and being made to thank him for the hard fuck and for using me like a piece of meat turned both of us on. He slapped my ass and made me beg into becoming his property.
I tried squeezing my sphincter to try to get an anal orgasm. I knew that David would likely not unlock me in the close future - meaning this was the best chance I had for an orgasm myself. I had no confidence of succeeding, however. My friend repeatedly hitting my prostate gave me some hope. Every time it got hit by his cock, I would let out an involuntary groan and leak even more precum.
David would sometimes pause to collect the precum that had pooled into my jock from the assault on my prostate to relube his cock, and would then continue ramming it deep into me. He would roughly rub under my balls to stimulate production. "Glad we found a use for your locked nub, apart from draining men's piss. Really cool that my faggot can produce lube for me." He would also hook his fingers inside my cheek, causing me to drool all over my chin and his hand. That also served as lube, to his amusement. This caused a vicious circle, as the ridicule and abuse would make me even more desperate and horny, making me leak even more.
"That's right faggot, squeeze that tight hole!"
He slapped my balls with his hand, which made me scream and almost pass out. The shock made me tighten my sphincter - with a roar, David shot his load deep inside me. I could feel ropes of cum hitting deep inside me.
"Wow bro, that was maybe the best orgasm I had in a while. First one of many, I hope."
He slowly slid his cock out of me. I wasn't left empty for long as he immediately shoved a plug in my hole.
"Gotta make sure you absorb all my cum. Real shame you're trapped in chastity, by the way."
He pushed me to the floor. I just laid there, spent.
"Crawl. All the way to the locker room."
I obeyed. Hands shackled behind my back, legs still cuffed together, plug lodged deep in my ass. The humiliating predicament, as well as my state of exhaustion, meant that I was heavily panting through the ordeal. Every pause I took was met with a firm slap on the ass or on the back - the welts from the whip were incredibly painful. I managed to grit my teeth through the pain the first times, but further hits made me yelp.
I finally made it to the locker room. I was a mess - I was still coated in piss and sweat, and a few drops of David's cum had slowly started leaking out of my ass.
"Congrats. I reckon the workout must've made you very hungry."
David pulled out a tupperware containing chicken, rice and vegetables, the same meal I had for lunch.
"Since you were pretty obedient, I won't piss in it this time bro."
He pulled out a dog bowl and a water bottle.
"Figure you'd still be thirsty though."
He laid the bowl in front of me and poured the contents of the bottle into it. I whimpered as I figured from the color that it wasn't just water - likely a mix of water and piss.
"Right, that's that done. Reckon it's time for you to go to sleep."
I looked at him, confused. Following his gaze, realisation dawned on me and I started to panic. David grabbed me by the hair and stuffed my mouth with his sweaty, piss-soaked underwear, silencing my pleas. He taped the gag into place, making me unable to spit it out.
"That's right. You're going in that locker. I'll lock you in for the night and free you before the gym opens. Don't worry about air, there are small holes in the locker doors."
He dragged me to an open locker, barely large enough for my size. I feebly protested, but David was far stronger than me.
I was pushed inside the locker. I was then placed in a sitting position, legs and arms cuffed together.
"Good night bro. Hope you sleep well, you have a long day ahead of you."
I let out muffled yells as he blew me a kiss, and slammed the door shut. I heard the click of a lock, and David leaving the gym.
