Sergio was 30 years old, tall, with green eyes, wavy light brown hair, muscular without being a bodybuilder, with soft, very white skin, and completely hairless. He was very handsome, without being particularly masculine, he didn't have any tattoos, his gait and behavior were those of a "normal" man, common.

However, he hadn't always been that way. When he was 10-12 years old, he was a "chubby" kid, and when he was 12, he suffered some bullying at school. It didn't matter, but one day, and due to the trust he had with his father, he mentioned it to him, telling him that they called him "fat" at school. His father thought that his son was handling it without much trauma, without much problem, but a few days later, he spoke with a friend, and this friend advised him to take the boy to the local sports center's pool. He told him that he knew a monitor, José, who, in addition to teaching swimming and establishing progressive schemes, knew how to treat overweight kids, stimulate them, and help them psychologically as well.

And so it was. Sergio's father took his son personally to the sports center and spoke with the monitor, who gave him a very positive impression. Sergio started going to the pool three days a week. He soon felt very comfortable, and little by little, he began to take José as a reference, to admire him more and more, to feel him as a pattern to imitate. On his own decision, Sergio started going daily, and the trust between them increased day by day; they talked a lot. José was interested in Sergio's concerns, and one day, talking about how he was progressing, he suggested that Sergio should, in addition to swimming, do gymnastics, and that, to start, he wanted to give him personalized attention, for which it was better that he came later, an hour before closing when there were fewer people.

Sergio's body was changing very quickly, partly due to the exercises he did, but also because it coincided that he was already entering the "growth spurt" of adolescence. This made him feel better about himself and, at the same time, admire José even more. One day, already at closing time, they were both changing in the locker room, and Sergio, seeing the monitor completely naked, could see his cock. He was amazed and couldn't take his eyes off it.

José: "What's wrong, Sergio? You're paralyzed."

Sergio (red as a tomato): "It's that..."

José: "What is it? Tell me whatever it is, I'm your friend, not just your monitor."

Sergio (stammering): "It's that I saw your cock... it's very big... nothing like mine."

José (laughing): "Ah, that's it! Don't worry, yours will still grow."

Now Sergio was 14 years old and had been jerking off for about a year. When he did it, he focused on the physical pleasure he felt, not many concrete images came to his mind, but when they did, his idol appeared in them. And that day when he saw the monitor's cock, he jerked off thinking about...
