"Hey there, Ronnie," Oscar greeted me, as I entered through the door. Just like two days ago, the gym was empty and the only ones present in the building were Oscar and me - complete and total privacy.
"Evening, coach! Here I am, ready for my training," I said, trying to hide the guilt in my face. Oscar raised an eyebrow as he saw my expression though. He seemed suspicious.
"Anything wrong, my boy?"
"No, coach, nothing at all," I felt terrible about lying to the man and tried to hide my shame by looking through my pockets frantically, "By the way... here's your underwear back, coach. Again, thanks a lot."
"As I said, don't mention it, boy," he chuckled as he took them from me, "I hope they were comfortable?"
"They fitted like a glove, coach."
He inspected the cloth for a bit with a bit of a confused look.
"Ronnie, did you wash these?"
"Erm... yeah, coach," I immediately started getting nervous and was hoping he wouldn't notice that I put them in the washer to get my cum out, "I kinda didn't want them to be damp from my sweat, you know."
His suspicious look didn't go away and it seemed like forever before Oscar responded to that.
"Well, thank you for taking care of it, Ronnie. Oh, by the way - I came up with an idea. Last time you misplaced your briefs somewhere in the locker room, right? So, for the future, I suggest we work out wearing a little... less."
It was my turn to raise an eyebrow.
"I'm sorry, coach?"
"No need to take any more sporting gear with, Ronnie. You just take you street clothes and leave them right here, on the desk - that way, there's less stuff that can get lost. It's much more natural for your body to exercise half-naked anyway! I'm sure you'll feel much more energetic if you let your skin breathe a little bit. And you don't have to worry about anyone seeing you, since it's after closing time..."
His hand slowly reached down to undo the knot on his workout shorts.
"I don't want you to feel weird," he assured me, "So I will do the same. What do you say, Ronnie?"
There was no saying "no" to him - not to Oscar. He knew what he was doing and no matter how strange it seemed to me, it wasn't up to me to question his methods. If he thought that it would be better for me to workout just in my underwear, then I was going to do it.
Plus, if he was going to do the same, maybe I could at least have some motivation to look at. You know, sort of like a goal I was headed to, sometime in distant future. Mere admiration, nothing more. And maybe just a little bit of curiosity...
"Sure thing, coach," I said with less hesitation in my voice, "Let's get to it!"
We both stripped down to our underwear on the spot. Oscar was wearing a bright red jockstrap showcasing his bulging meat in the front while uncovering his ass in the back. Very functional, I thought, maybe I should get a piece of underwear like that. Oscar definitely wore it well. His rock-hard muscles looked amazing with the jock, supported his giant bulge and really made the comparison between him and me stand out.
Fuck, if I knew this was coming, I'd wear something a little better than my baggy boxers...
We soon started and Oscar gave it to me hard once again. We went from one machine to another and there was no mercy. Oscar remembered the limits he found on me during our last lesson and was determined to push them. He kept telling me that if I was serious about getting better, I should always push more and more and never stop for the sake of being "good enough". At the same time, he said, it was important to appreciate the body I currently had, though - that I should stay both proud and motivated. He frequently groped on various muscle groups on my body as I was working out, examining them with his expert touch - making sure I was flexing correctly and that they were properly stretched.
"That's it, Ronnie, push and pull. Twelve more to go," he whispered right into my ear as he was behind me, his hands on my arms and his amazing body pushing against me, as I was struggling with the handles on one of the machines. I remembered the dream I had the night before and was praying not to let it give me a hardon... it would be very hard to disguise anything in these terrible boxers!
"I can tell what you have potential, Ronnie," he said to me, as his fingers were running against my muscles, which I was flexing to the max, "You have a good body type. You just need some exercise to get it all going. Before you know it, you'll be so jacked you won't recognize yourself in the mirror."
His words genuinely warmed me up inside and made me a little happier about myself but his distracting fingers made it really hard for me to keep my mind from slipping into indecent thoughts. Sweat started dropping from my forehead onto the towel I put below me as I tried to keep my focus on the weights and not Oscar's body. My dick was already semi-hard.
"Okay Ronnie, that was enough. Good job. Let's move on."
I got off of the machine and tried to do it carefully, as to not show the growing tent in my boxers. Oscar, of course, noticed almost immediately. His hands landed on my shoulders and gently turned me around to meet his smiling face.
"Ronnie?" he asked me, "What did I say about being ashamed of what happens to your body?"
I instantly went fully red in the face.
"You told me that it happens to everybody..."
"That's right, Ronnie," he said and then, to my surprise, his hand went for his own waistband and pulled down his jockstrap in one quick motion. I saw that Oscar's big, uncut tool was semi-hard - just like mine.
"It happens to me all the time," he said as his hand gently rubbed my shoulder, "Now, please, take off yours as well, too. I don't want you to feel like you have to hide anything from me."
I hesitated. I didn't really want to parade around my average cock, incomparable with this man's weapon. But coach's wish was an order... My thumb went under the waistband of the boxers and let them fall on the ground.
"There you go," he said, as he patted me on the shoulder, "Now there's no secrets. Come on, time for your last set. Let's do some bench presses."
