It had been two months since I first agreed to be a human urinal at Jon's bar and had undergone a total transformation training session with Uncle Bob. I spent two days a month in full rubber and installed as a urinal at the bar. The sessions were always hot, with lots of piss and cum to keep me well fed.
Uncle Bob and Jon had seen to it that every day I "worked" the bar was packed with patrons. The fun just kept getting better and better.
Just before I was supposed to start my third month as the urinal, Uncle Bob called me up.
"Hey pup," Uncle Bob said when I answered the phone. "Come on by my place. I've got something for you."
Never being one to disappoint Uncle Bob, I readily agreed. "Sure thing, I'll be right over." I threw on some clothes and drove over to his house. My cock ached with anticipation of what he had in store for me. Uncle Bob rarely called me over unless it was for training or using my throat or ass.
I walked up to the door, knocked, and walked right in. Uncle Bob was seated on the couch, naked, his beautiful cock dangling between his legs. He turned to face me as I walked in.
"Glad to see you, pup," Uncle Bob said with a smile. He stopped me before I could drop to my knees and engulf his cock. "I have something special in mind for you today, pup."
I looked at him strangely.
"More training...this time we're taking your urinal and cum dump training to the next level."
I immediately became hard as a rock. Uncle Bob was never direct like this. He usually waited for me to service him and then would talk about new things for me to try out sexually.
"Yes Uncle Bob. What do you want to train me in next?" I asked, kneeling before him.
"We already know that you are our piss and cum dump, and you've come to be a urinal slave in the last few weeks. So we've decided to take your transformation one step further." Uncle Bob's cock was hard, but he was still denying it to me. It was glistening with precum and I longed to suck it and take its hard length down my willing throat.
Uncle Bob got up from the couch and walked over to a box that was sitting on the nearby table. He opened it up and started pulling out new toys and gear. There was a much larger butt plug, a new hood, and a few tubes. I had no idea what Uncle Bob had in mind, and that had my cock dripping.
"Strip out of your clothes, and put on your rubber suit, pup. We are going to transform you here and now."
Obediently, I stripped and changed, putting on the full rubber body suit. Once changed Uncle Bob stepped up to me, new hood in hand. "This rubber hood will engulf everything on your face. You'll have two little nose holes, and your mouth will be gagged open," he said as he slipped the hood over my head, I heard the buckles and locks on the back click shut. I was fully engulfed. I couldn't see anything, and hearing was difficult but not impossible.
It was odd, this whole set up, usually Uncle Bob would have me service him, but he was also asserting his dominance over me. This, more than the gear was turning me on.
Uncle Bob felt me all over before continuing. "Next, I am going to insert two breathing tubes in your nose, keeping your airway open at all times." I felt the tubes enter the hood and then shove up inside my nose. I started to protest, but it was futile. I could only moan through the open mouth gag of the hood. Once the tubes were in place, I was breathing through them normally, but couldn't control my inhalation at all. There was a slight whistling as the air moved in and out of the tubes. "Now I am going to insert an inflatable funnel gag in your mouth, and a feeding tube from your cock, and as a last touch, we are catheterizing you."
My cock jumped in the rubber suit. I couldn't believe what Uncle Bob was saying. He was slowly taking away my control over my bodily functions. I couldn't control my breathing, he was going to plug my ass with a massive butt plug, and this one I hoped would be a vibrator like the last one. Soon, I would lose control over my own bladder. I knew that the catheter would snake its way up my cock and deep inside my prostate and eventually up into my bladder. Once locked in place, I would have no control over my ability to urinate.
I felt the funnel gag slide inside my mouth. I moaned long and low as I felt the gag inflate. Uncle Bob had also slipped the feeding tube into my mouth, stringing it through the funnel gag and down my throat. I suddenly felt so stuffed, utterly helpless. Little did I know, the feeling was just beginning. Before he continued outfitting me, Uncle Bob moved me around the room. He helped me up into the playroom, I could tell by the feel of the floor under my feet. Uncle Bob assisted me as he placed me on a small elevated platform. Once there, he tied my hands behind my back and had me kneel down. As I knelt down, I felt something cold and firm against my vulnerable hole...the butt plug. It felt so big as it pushed against me, pushing inside me, splitting open my boy hole.
