Guy I work with at my new job is really cool. We have a laugh and he's great at teaching me how to do everything. We have a lot of long shifts together away from the other guys and from the first day he was so casual it didn't seem weird at all that he'd be telling me how something works while his protective work pants really didn't fit his body, but it didn't stop him working fast and precise. There would be times when his back was to me and his pants had slid way down so that I could count the spots and hairs on each of his butt cheeks. He didn't seem bothered at all and while I was paranoid the others would see it, it quickly became pure bliss to be around him. I stopped worrying about if my own pants were up tight and felt so protected when the roles reversed, him behind me as I felt my pants barely cover the bottom of my ass. He didn't say anything, when I turned back around he was totally chill but quietly holding a bump in his crotch. His underwear always bunched up in a way that meant they didn't cover anything important and his body was so big and strong his cheeks were pretty much fully out.
Now and then we'd move up close to each other that my bulge would slide between his bare cheeks or his mine. Again it was so natural and chill, some kind of mutual respect between us.
A couple days in we were more comfortable with each other. Burping, farting with no shame, even enjoying them properly like you're alone. Even as his sweaty tangled up pants pulled across his cheeks, he would even begin to fart while I was behind him and I could see his cheeks part and his hole begin to open before he pushed it out. An instinct told me to put my lips straight over his hole. But I was too mesmerized watching it happen. Seeing and hearing his fart followed by a smell that made my dick harden and my mouth water.
I didn't shove my mouth in yet but I got my nose holes right up against the wet juice of his hole. Neither of us had ever had someone appreciate their bodies like this before. I was shy at first but since we started having lunch beers the farts quickly came.
i dunno how we got any work done but even that was like clockwork, the two of us. We were like two parts of a machine, and while one part worked the other maintained it, observed it, assisted. Everything we'd done had managed to occur in an unspoken way without interrupting work. But I knew giving my tongue to his hole would be different.
Sometimes a fart would be extra wet so I would lick it just to clean it, or move the juice with my fingers to my own hole. My tongue wanted to go inside but I wasn't sure what that led to. The sweat of the job made both our holes easy to slip into.
I worshipped his cheeks when my face came into his crack to pleasure or clean him. We stopped wearing underwear altogether since we swapped them to use as face cloths after work one day, so now when we worked together we were commando with the jeans barely covering our dicks and none of our asses. Since we worked in the rain a lot and our pants were soaked anyway, we cut down time away from site by pissing straight in our pants. It would mostly end up to the ground and just add to the amazing smell of both of us combined.
Eventually he was bent over right in front of my face and he let out a fart so sloppy I could tell my tongue would slide straight into his hole. It just happened, and I could feel and taste the expanse of everything in his ass. More sweet farts, salty juice and some bitter gravel. Just having my tongue in his hole made my own hole gape in sympathy. I was totally at home in all the smells and juices that came with him.
He finally moaned and dropped his tool as I gave him everything my mouth could right there. From that first day with just a hint and a tease but something mesmerizing. I wrenched my dick from my piss-stained pants, rubbed it in all the juices of his crack, and slid it gently into his hole.
It was like a hug that not just felt good, but tasted and smelled it too. As soon as my dick was inside him and began to move in and out, his hole gaped even more spluttering dirty juices all over. My dick throbbed and so did his asshole around it and they did this in turns like kisses.
