The porta-potties down at the construction site had to be one of the least romantic places on earth. They were hot, dirty and smelled like piss. But Juan insisted that they were the best place for our “meetings”.  He would text me a photo of his big brown cock and tell me get over there to help him out. I think knowing how dirty and embarrassed it made me feel to get bent over and fucked in the construction site shitter, made him enjoy it more. It sometimes seemed like Juan went out of his way to make sure that anyone within earshot would know he was pounding my ass hard, using long, hard strokes to get the plastic building rocking, while verbally calling me a dirty whore and a cunt. Most of the time, we were alone on the site, so it did not matter, but today, the site was open, so there were construction workers everywhere.

As I walked towards the row of little blue buildings, I noted all the men in tool belts going about their business. My cock was rock hard in my shorts and tenting them visibly. Juan had conditioned me, at this point, to get aroused whenever I got close to those smelly, little blue boxes. That foul stench of piss made my ass twitch with emptiness, knowing soon, it would be filled with thick dick.

As I opened the door, I saw Juan sitting there, grinning at me, his cock already fully hard. I squeezed in and immediately dropped to my knees and started sucking. Juan put his hands on the back of my head and started pounding my face. “Your training is coming along nicely, bitch.  I no longer need to tell you what to do, you just get to work.” I was somehow proud of the praise he had just given me. It felt good to know I was servicing him properly. As I was deep throating his meat, I noticed a breeze of “fresh” air in the stuffy little box. Out of the corner of my eye, I noted that someone had drilled a 3″ hole in the blue plastic side or the building. That was when my focus returned fully to the task at hand.  Juan started skull fucking me hard. Pounding my face into his crotch, full force, opening up my throat to take him “balls deep”.  He was also getting verbal, telling me to take it, and calling me a whore. In the back of my mind I was aware that any of the construction workers in the vicinity would know what was going on in this portable toilet. I was embarrassed and ashamed that I had sunk this low to get cock, but Juan had me under his control, and I knew I would do anything he asked. His cock felt that good as he used me. As these thoughts ran thru my head, Juan pushed his thick cock deep and started unloading. Normally Juan shoots a big load, but today it was enormous. I could not swallow fast enough and cum started dripping out of my mouth at the edges.  As he pulled that monster out of my face, part of his cum load splashed out covering my chin and the front of my tee shirt with spit and jizz. Wasting no time, he flipped me around and shoved his throat-slime covered cock into my ass. I screamed out at the force of the intrusion, again alerting anyone in the vicinity, as to what was going on.

Juan pressed his hand on my shoulders bending me over, so my face was smashed against the blue plastic wall. He adjusted my position until my mouth was at the hole drilled in the side of the box. Immediately a cock was shoved into my mouth.  The surprise of this action, allowed the anonymous man to get his dick deep into my throat before I could think to stop him. Juan kept fucking me hard, forcing me to stay pressed tight to the hole, unable to remove myself from the cock plunging into my mouth.

“Yeah, that’s the way, service his cock properly, like I trained you. Let him use you like a whore. Cause’ that’s what you are now…a whore. These guys are paying me to use you. It’s all part of the service. I not only provide and maintain these porta-potties, I provide and maintain glory hole sluts to service the work crew on weekends. You have been trained over the last few weeks to provide this service. You are now so cock hungry, you will take any dick offered to you.”

My mind was reeling at what Juan was saying.  He turned me into cum hungry whore. The cock in my mouth exploded.  I swallowed the strangers cum, and he pulled out. Another cock immediately took its place. My reflex action was to start sucking, to properly service the man and make him cum. Juan slowed his ass fucking, pumping in and out of me with long, deep strokes. This allowed him to continue using my ass while multiple men came and went in my mouth. 

“OK I think you understand what is expected of you. Just keep the cocks in the hole happy and satisfied.” With that he finished up and shot his load in my stretched out and fully open ass. As he was zipping up his pants, he patted me gently on the back of my head, the way you would pet a dog, that had learned a new trick.

“If your jaw starts to get tired, feel free to give it a rest. Just spin around and stick your ass against the hole.  These guys will be just as happy fucking your cunt as your face. They are working three shifts this weekend to get ahead of schedule, so you are going to be busy. I will be back Sunday night to let you out.  Your 48 hour shift as a glory hole cum bucket has just started.  Have fun!”

As he opened the door, a breeze of cool air filled the toilet. I think at that moment we both realized how hot the little plastic box had gotten.

“You are going to be swallowing a lot of salty jizz, working up a sweat and your new home really collects the heat from the sun. I suggest you stay hydrated. Since you are occupying the toilet, just tell the men in line you are feeling dry, and I am sure they will be happy to piss in your mouth to quench that thirst.”

As the door closed, I could hear Juan install a padlock on the outside, securing me inside.
