Busted by a trainer at the gym

"You're a filthy little fuck, aren't ya?" 

This is what I heard as I leaned over to grab a drink of water from the fountain near the locker room.

I turned around to see who this vaguely familiar voice was coming from. I was shocked to see Calvin staring back at me with a shit-eating grin on his face.

I work our regularly at a small personal training gym. Marcus has been my trainer for the past 5 years. He's taken me from Dad bod to a fit 50 year old. Calvin is a relatively new trainer at the gym but from the first time I saw him, I've had a hard time averting my eyes off him. 

I'm a white, Italian guy, about 5'8", 160 solid pounds. Hairy chest and from the waist down. Solid glutes and legs. What I lack in cock, I compensate for with a nice, round ass. Calvin is not the type I have ever been attracted to before. But something about his physique and the way he carries himself had me mesmerized. I'd watch him work alongside his clients, patting them, holding their form and sometimes stretching them after a workout and many times found myself getting ridiculously hard. He has incredible, muscled arms, a chiseled, but not overly big chest, washboard abs and an ass that rocked my world --  high and super firm.

I don't think I had ever even beat off thinking about a black guy and here was Calvin literally making me produce so much pre cum which I was often forced me to unstick my dick from from underwear several times during a workout.

"Shit -- I'm busted" I thought to myself while looking back at Calvin with a somewhat confused look on my face, "I'm not sure I'm following ya, bud?" "My name is Calvin," he said, extending his hand. "I could swear you were undressing me in your mind and imagining a lot of nasty shit...I know that look. I've given that look. You got it bad, bro."

My mind was in overdrive. Do I finally admit to another guy that I'm hot for him vs. my history of clandestine, relatively anonymous, past encounters with guys? Do I pass it off as a joke -- that has was totally mistaken? Calvin seemed too wise for that and looking him in the eye I saw a mixture of sexy and sympathy in his eyes -- a signal that made me feel OK revealing the truth. It took all the courage I had to admit that I did indeed imagine (on many occasions) his amazing ass sitting on my face while I licked and sucked on his hole. "It's alright bro" he said, putting me at ease. "I'm a dirty little fucker too and probably watching you as much as you been watching me. In fact, guys like you are my speciality...all burning and hot on the inside and waiting for someone to have the balls to pull it out of them." My head was spinning at this point, unsure what to say but my lips look over, spewing words before my brain had a chance to engage. "Guilty as charged" is what came out. Calvin's perfect-teeth smile only got wider. "My place is about :10 from here...let's grab a shower and head over.

I headed into the locker room, trembling as I removed my clothes. I wrapped a towel around my waist and headed into the shower expecting company, but I did not see Calvin -- I assumed he went back to the gym. As I showered, I practically beat off -- it was so hard to keep my hands off my dick, nipples and ass. My body was vibrating in antipication and fear. "What the fuck am I doing?" I said to myself. I stepped out of the shower and straight ahead was Calvin, pulling up his boxer briefs. There must be a special shower for trainers that I was not aware of. It was just enough to give me a glimpse of perhaps the most perfect ass I have ever seen. I also got a good look at the rest of his body which must be about 5% body fat because his abs were incredibly tight and pronounced. He turned, look at me and said "nice swol" referring to my post workout pumped chest. Calvin finished dressing -- his jeans-covered ass was a sight -- and headed out after quickly giving me directions to his place.

Still in disbelief, I got dressed, dried my hair and without a rational thought in my mind, drove to the address Calvin gave me.
