Curious Boy's Vitamin D (Part 2)

That night again I left for bed agitated by the vision of Uncle Sergio under the shower, his image like a moving photo repeated in my head and my dick got so hard it started to hurt and that sensation of having to pee that wouldn't calm down even when I had spasms, a feverish heat and electricity running down my back. That tickle in my balls that felt so good and gave me so much pleasure

I spied on him for three days every time he entered the bathroom to shower, he was my new toy, nothing interested me anymore except getting to my secret adventure hour. We were alone in the house and no one could discover my bravery, only he; And I was very sure of my following and that he didn't suspect it.

On the fourth day, while he was soaping his dick which seemed thicker and fatter than usual, I could see how the caresses he gave himself to wash well took on a continuous and more violent rhythm, his face and muscles tensing as he applied more or less rhythm to the vaivén of his hand; my throat dried up and I felt my heart racing that was going to burst out of my chest.

Sometimes I saw him pull back the skin of his cock all the way back to the head of the cock which left it all outside the foreskin, his balls rose, his abdomen got hard and his eyes went blank at the same moment as a white liquid started to flow through his cock and dripped from his balls along with the water that fell on the floor. I heard him groan with muffled grunts that somehow infected me with their intensity.

I thought I was going to die when I felt like he finally peed on me. It was an enormous sensation of pleasure that wrapped my body in uncontrollable spasms that I couldn't dominate. It was the first time I saw a man doing himself a terrible and beautiful masturbation, even today as an adult the memory excites me so much that I masturbate with the image of Uncle Sergio massaging her cock in the shower.
