Coach Marko informed me that we would be doing a new kind of workout which focused on just one muscle of the body. As I approached our private workout space, I couldn’t help but wonder which muscle he’d be paying special attention to—and whether it was a metaphor or not.

After all, last time I talked to the Coach, I mentioned that the boys and I got together in the locker room and ended up having a circle jerk. Naturally, we compared cock sizes. We even compared how low our balls hung, before busting our thick loads onto the floor of the locker room showers. Although a positive experience, it left me wondering if my cock was enough. Am I thick enough for our Coaches? Am I able to get hard enough to pump our Coaches into pleasure? That’s why when Coach Marko called me, I jumped at the opportunity for his guiding hand.

Coach and I sat and I told him what’s been on my mind lately. He was understanding and quick to give positive feedback, telling me that my cock is perfect. I was hesitant to believe it—I had seen the other boys—but his tone was genuine enough that I was starting to believe him. I guess that pep talk gave me back my confidence.

He asked me if I wanted to try something. He pulled out a device I had only seen in porn videos I jerk off to late at night—a cock pump! I smiled and agreed immediately as I followed his directions. I pulled off my shorts and presented my already hardening cock for him to try his new device on.

My cock was so hard just from seeing the Coach that it could barely fit into the pump. As the device lowered on my dick, I could feel the blood rushing from my body to the base and finally to the cockhead where a sparkle of precum formed. I’ve never felt so hard before, my cock was throbbing so much I thought the cock pump would explode if he pumped any more air into it. The blood rushed from my brain down to my cock and now my only instinct was to get inside my coach’s hole.

After he removed the pump, I felt like I had the biggest cock on the team. And it ached—Coach Marko was going to take the hardest pounding of his life. As the big, beefy coach got up and stripped into his jock, all I could do was stare and lust for that hole of his.

He was tight. I filled every inch of his hole. I worried for a second that my cock was going to tear him in two, frankly. His face twisted with both pleasure and pain as I pumped into him with no thought, just pure carnal instinct. My head was in a haze as I thrusted into my Coach, pumping and pumping until the cum swirling in me could no longer be contained. I needed release. Now.

I pulled out and jerked myself over his hairy chest, blowing my load past his stomach in thick ropes. I used the rest of my cum to stroke over my cock, as if it were lube, and pushed back into him. I fucked him deeper, savoring each pump. I was in such a daze I think I even pumped another load into his hole, but I could barely keep track. What I do remember is that, as I pulled out of him, I had no more qualms about the size of my cock. I honestly think my cock will stay this hard until our next session together… and if not maybe we’ll just get the pump out again.
