I don't know how he knew. I've never said anything to him nor to anyone lese, and I don't think that I have ever done anything that could reveal my crush on him. I suppose he figured it out by the way I looked at him.
He's my gym teacher. He's in his 40s, a tall, well-built man with a hairy, muscular body, brown hair, and intelligent blue eyes. He's a tough guy, always asking a lot of his classes. I used to admire him when I was younger. Recently, I had begun to wonder what it would be like to have sex with him.
He had been hard on us this lesson, forcing us to run, climb ropes, jump; we were all exhausted by the time he told us to hit the showers. The pass had been tougher for me than for the others, I think. I'm no jock. I'm short and slim, and even though I'm 18, I know I look younger, with my "petite" appearance. While the others went to the showers, I just sat there and tried to catch my breath, and by the time I had gotten out of my sweaty clothes, the others were already getting dressed. I went into the shower and sighed of relief when the warm water ran over my tired muscles. For a moment, I just stood and stretched under the running water. I heard the others leaving, and there was a moment of silence before I heard the door open and close. Apparently, someone had forgotten something and come back to get it.
I jumped when I felt a hand on my shoulder, and I turned around. It was Mike, my gym teacher. He was naked. My eyes wandered over his hairy chest down to his thick, semi-erect dick, and as I realized that I looked at it, I quickly looked up again, into his eyes.
-Do you want me to rub your back, Anthony? he said.
-Uhm... I said, not sure if he was kidding or not.
-Turn around, he said, and I did as I was told.
His big hands were hard against my skin as he put soap over my back and washed it off.
-You've been looking at me in class, haven't you, Anthony? he said.
He held shampoo in his left hand and began to rub it into my hair. I didn't know what to say, so I just stood there, quiet, enjoying the feeling of his hands touching me.
