I knew the moment the cute little blond twink strolled into my storefront gym that I was going to have him, but by the way he shrank away from me and trembled a bit when I approached him, I also knew I would have to prepare for that moment well.

“Hi, I’m Rod.” I said pleasantly. “I run this place and act as personal trainer. And who are you and what are you interested in?”

I had hoped that he’d say right out that he wanted to be fucked by a horse-hung muscle stud like me, but he didn’t respond to that innuendo.

“Hi, Rod. I’m Craig. I’m tired of everyone thinking I’m too young to buy beer. I want to bulk up.”

“You mean something like this?” I said, and I pulled my gym T over my head. I could hear Craig gasp when he saw my massive, well-cut torso.

“Y-e-s-s,” he stammered out.

“Well, let’s see what we have to work with,” I said pleasantly. “Off with that T-shirt.”

He stripped his T off, and I could tell right off that he wouldn’t bulk up very much, although we could do something with those pecs and abs. But I also saw that I wouldn’t want him to bulk up too much. He was one beautiful twink. It set my cock to twitching just to see him.

But I told him that I could help him if he came in twice a week. And he did that for the next two months, during which time I unfolded my plan to have my cock pulsating inside his cute little bod. I gave him a lot of personal attention, telling him that I wanted him to go shirtless in his workouts so I could see what was being worked out and how well in the exercises and that I would go shirtless as well so he could see what muscles were being worked with the exercises. And I gave him plenty of muscle work to see during the workouts—all except for the one muscle I really wanted him to see. I took care of that by hitting the showers whenever he did and giving him a full display.

For the first couple of weeks he remained ultrasensitive to my touching him or even coming close, but I was persistent in needing to put my hands on him to show him how to do the exercises properly, and slowly but surely he let me touch him and, with time and confidence, to let my hands linger on the curves and folds of his torso and legs during the exercises. And he was lingering longer in the shower as well. One evening after two months of preparation, I began to slowly stroke out my cock while we were in the shower and I was sure he was ogling me sideways. His eyes bugged out and he dropped the soap. When he bent over to pick it up, I almost took him then, but I didn’t. Others were in the gym. I needed to wait a bit longer, and needed him to signal his willingness.

On his next visit, I decided to bring this to a new level. We were over in the corner of the room, away from the storefront picture window and everyone else working out
